Flow Options

Flow Options establishes flow limits to aid in the detection of possible flow problems.

1. Flow Options

Setup Flow Options WED 5:43:40 PM |Limits |Monitoring| Monthly Limit 9999999 Main Line Limit 0500 Unscheduled Limit 0000 Flow Check Delay (m) 2

Limits

Monthly Limit: The number, in total gallons, that the irrigation system should not exceed per month. If it does, the DX3 controller will either generate an alert (and keep watering) or simply stop watering until a new month begins. Watering can also be resumed by increasing the monthly limit.

Main Line Limit: The number, in gallons per minute, the flow of the main line shall not exceed. If the calculated flow ever does exceed this number, an alert will be triggered condemning all irrigation until cleared. The number should be set to a value higher than the flow if all simultaneous stations (six) are “on” but lower than if there is a main line break.

Unscheduled Limit: During periods of no programmed irrigation activity or no manually activated irrigation, the flow in a system should be zero. The Unscheduled Limit number, then, is the number in gallons per minute set to trip an alert if flow is detected during these times of inactivity, condemning all automatic irrigation until cleared.

Unscheduled flow conditions may be due to broken water lines, defective valves, faulty solenoids, and/or more.

Flow Check Delay: When a valve is activated, the initial flow rate may be significantly higher than the valve's “steady” state. This could be due to drainage of water lines, waiting for pump water, or other. The initial high flow rate could therefore trigger many unwanted and premature alerts. This Flow Check Delay delays the calculation of flow for a period of two to nine minutes to allow the flow to stabilize.

To set this number accurately, observe which station takes the longest time for its GPM rate to stabilize. Round this time period to the next minute and use that rounded value as the Flow Check Delay value

Press or to get to "Monitoring" Flow Options.

Monitoring Flow

Once the station flow limits have been established, the flow limit checking (upper and lower limits) may be enabled or disabled. When upper limits have been enabled, all station upper limits will be enforced on an individual station basis. When lower limits have been enabled, all station lower limits will be enforced on an individual station basis.

Setup Flow Options WED 5:43:40 PM |Limits |Monitoring| Enable Max Flow Limit Enable Min Flow Limit

The default is disabled, meaning no limit checking is performed. However, the GPM flow and total monthly flow are still calculated. Monthly limit, main line limit, unscheduled flow, and flow check delay are always enforced regardless of the flow limit monitoring settings.

To Enable Max and/or Min Flow Limit Monitoring:

1) to switch between the check boxes.
2) to turn on or off desired option.

Learn Flow/Current

For the DX3 controller to issue meaningful alerts when there is a flow or current problem, the proper flow and current rates must be “learned” by the system. The Learn Flow/Current command therefore teaches the DX3 system the nominal (ideal) current and flow settings to each valve and station. One would typically activate the Learn command for either a new system or when a when a new flow meter has been installed.

Setup Learn Flow/Current WED 5:43:40 PM |Current % |Flow % | % of Nominal Current: Upper Limit %: 0.05 Lower Limit %: 0.05 Learn Flow/Current Setup Learn Flow/Current WED 5:43:40 PM |Current % |Flow % | % of Nominal Flow: Upper Limit %: 0.05 Lower Limit %: 0.05 Learn Flow/Current Start Now All Satellites □ Delay Learn Until □ 09:12AM 02/10/17 Include Current □ Include Flow □ Status: Off Flow: 0 (GPM) Cur: 0.01

The Learn Flow/Current command consists of three screens:

Current %'s: Setup the Nominal Current limits. Use the Control Dial to switch between and adjust the Upper and Lower Limit fields. Recommended value for Upper Limit and Lower Limit is 30% for both.

Flow %'s: Setup the Nominal Flow limits. Use the Control Dial to switch between and adjust the Upper and Lower Limit fields. Recommended value for Upper Limit and Lower Limit is 20% for both.

Use the Control Dial to activate the Learn Flow/Current command, triggering the 3rd screen above.

If the “All Satellites” check box is checked, the learn function will be performed on the submaster and all connected satellites.

On the 3rd screen, two things:

If your new system does not have a flow meter installed, be sure the Include Flow checkbox is blank.

If you are running the Learn Flow/Current command due to a new flow meter being installed, be sure the Include Current checkbox is blank.

Omit by Date

The DX3 allows up to 48 days to be excluded from irrigation per year.

5) to set desired option.
6) Repeat steps 1 - 4 for all days to omit.

Press out to get to the next group of Omit Days.

Communication

Submaster

If the Submaster option is active, that means the DX3 controller has a direct link to the Central computer. The controller can communicate with the Central in any one of six methods:

Setup Communication WED 5:43:40 PM Submaster |ENET |WiFi |M7/8 |Cell Submaster Submaster Com: Raveon M8 Submaster Address: 240 Cloud Connect: Off Raveon M8 Ethernet Wifi Other Digi Cell Raveon M7 Serial Off Ethernet Wi-Fi Cellular

• Raveon M8 (UHF radio)
- Ethernet
- Wifi
- Serial
• Digi Cellular
- Other

The Submaster Address can be any number between 0 and 999. If you were to have more than one DX3 controller as a Submaster attached to any one Central computer, be sure they have different Submaster addresses.

Use the Control Dial to activate, select a communication method, and assign an address for these fields.

Press off to get to "Ethernet" screen.

Cloud Connect

Cloud connect provides a method for remotely accessing the irrigation control. The user has an option of using cloud connect via Ethernet, Cellular or WiFi.

Cloud connect is mandatory for cellular communication to the Central and optional for WiFi or Ethernet communication to the Central.

Ethernet

If the Ethernet or Wifi communication method is selected in the previous screen, it might be necessary to configure the DX3's TCP/IP settings.

If your network uses Dynamic Host Configuration Protocol (DHCP) to dynamically assign IP addresses, then simply leave DHCP Client set to YES.

If, however, your networked devices require static IP addresses, change DHCP Client field to NO and, using the Control Dial, enter the appropriate IP address information. Contact your network administrator for the correct configuration information.

Setup Communication WED 5:43:40 PM Submaster ENET WiFi M7/8 Cell Laguna Port: 10001 (Requires reboot) DHCP Client: YES

LAGUNA Port defaults to 10001. If separate WLAN ports are desired, they must use a unique LAGUNA Port (a rare-use case).

WiFi

The WiFi menu is used to select the wireless network to connect to (SSID). Enter the network password (KEY) and select the password encryption type (Encryption).

The controller does not have the ability to scan for available WiFi networks; the WiFi network name must be entered in manually (case sensitive).

When inputting SSID or KEY, a user can select uppercase, lowercase, numbers or characters by scrolling the wheel.

Current Checks

The DX3 controller allows the operator to limit and view the controller's output current (Amps) usage. Much like established flow limits aid in the detection of problems with the system, establishing current limits aids in detection of field wiring problems associated with any station. Monitoring features include:

• Display of the total, instantaneous current on a per station basis

• Automatic termination of station output and reporting of station status when the preset maximum current is exceeded

• Automatic termination of station output and reporting of station status when current stays below the pre-set minimum

- Review of station status reports via the Warning/Alarm display

• Automatic current limit setup.

Setup Current Checks WED 5:43:40 PM Enable Max Current Limit Enable Min Current Limit

For a complete explanation on current monitoring, please see Appendix C: Current Monitor.

To Enable Max and/or Min Current Limit Checking:

to switch between the check boxes.

2) to turn on or off desired option.

Current limits can be set manually (Stations-->Current) or "learned" (Setup-->Page 2-->Learn Flow/Current).

Firmware Update

Rain Master continually strives to enhance the performance and functionality of its controllers. Occasionally, a firmware update might be necessary for your controller.

Firmware Update WED 5:43:40 PM Firmware update complete

Steps

1. Download the latest firmware driver from Rain Master's website. Copy file to root drive on a USB drive in folder labeled "FirmwareUpdate". Be sure your DX3 controller is on.

2. Accessing the TM from the bottom, insert the USB thumb drive with the latest firmware update on it into the USB slot.

3. The controller will beep and let you know it has detected a USB thumb drive.

4. Navigate to Setup-->Page 2-->Firmware Update.

1. The DX3 will update the firmware. Once complete, the DX3 will display reset.

2. Remove the USB thumb drive.

An instructional video on how to update firmware is located on the Rain Master website, www.rainmaster.com.

FLOW MAX

FLOW MAX is software that allows the DX3 to intelligently share resources and manage operations for satellites using a single point of connection. The shared resources may include common pumps, master valves, and/or flow meters.

A FLOW MAX system is comprised of a number of DX3 controllers (typically 3 to 5) with the first controller set up as the submaster. The remaining satellites are set up as slaves.

Setup FLOWMAX WED 5:43:40 PM FLOWMAX Participant (Submaster always Flow Max Part) Devices Connected to this Clock: Pumps: Master Valves: 1 2 3 Flow Sensors: 1 2 3

FLOW MAX provides a means to detect station flow limits and main line breaks within design and programming parameters. All controllers participating within a FLOW MAX system must be programmed as participants from each of their respective control panels.

In order for flow volumetric totals to be tracked/logged at the controller and in Laguna central software, the selection must be made under "Devices connected to this Clock" for the flow sensor point of connection.

Please see Appendix D: Setting Up a FLOW MAX System for a complete explanation on FLOW MAX and setting up a FLOW MAX system.

Station Count

It is possible to manually change the station count. The station count variable dictates how many stations participate in the Learn Current/Flow events.

Station Count WED 5:43:40 PM Station Count 048

Master Valves & Pumps

This screen allows the operator to setup up current limits for the master valves and pumps that can be connected to the DX3 controller.

The master valve can be set as either Normally Closed (N.CL.) or Normally Open (N.OP.)

It is also possible to have the DX3 controller "learn" the different current settings for the MV or pump installed.

Connection

Used to distinguish between a 2-Wire or conventional MV / Pump.

Program Decoder

This screen allows the operator to program any decoder plugged into the Programmer port of the 2-wire card for the DX3 controller.

1. Connect the desired decoder. The DX3 will read the current address and the type of decoder (station, flow, or moisture) and display that information.

Program Decoder WED 5:43:40 PM Current Address 001 New Address 002 Is Address Valid YES Decoder Type Moisture Port ① of 3

1. In the New Address field, change the value to desired address. Push Control Dial to enter.

2. Be sure to mark the decoder with its new address.

A station decoder address is its station number.

A station decoder cannot use the same state address/number as a conventional station.

Valid station decoder/address range is 1 - 200.

Fixed address ranges are used for MVs / Pumps.

Master Valves 1 - 3 and Pumps 1 - 2 use the following fixed addresses:

$$ \mathrm{MV1} = 2 0 1 $$

$$ \text { Pump } 1 = 2 0 4 $$

$$ \mathrm{MV} 2 = 2 0 2 $$

$$ \text { Pump } 2 = 2 0 5 $$

$$ \mathrm{MV} 3 = 2 0 3 $$

Moisture decoders are addressed 1 - 16 based on the irrigation program to which they are assigned to monitor. For example, moisture decoder 2 will monitor irrigation program 2.

Flow decoders are addressed 1 - 3 based on the flow sensor number. For example, flow decoder 3 will be assigned to flow meter 3.

For more information on 2-wire decoders, see Appendix D.

Chapter 5: Program Entry

The DX3 controller allows the user to program irrigation schedules for up to sixteen programs. For an irrigation program to be considered valid, it must contain:

• at least one start time
  • at least one active irrigation day
  • at least one station assigned to the program
  • and a run time assigned to each station

Start Times

The DX3 controller is capable of handling 12 start times per program. The Start Time is defined as the precise time of day that a given irrigation or auxiliary program begins.

Program 1 Start Times WED 5:43:40 PM 1-6 7-12 Start Time 1 Start Time 4 06:15AM --:--AM Start Time 2 Start Time 5 08:00PM --:--AM Start Time 3 Start Time 6 --:--AM --:--AM

The procedure to set Start Times was covered in Chapter 3: Quick Start.

Water Days

The DX3 controller offers three modes with which to create an irrigation schedule.

• 14-day: Create an irrigation schedule over a two-week water cycle.
• 31-day: Create an irrigation schedule over a 31-day water cycle.
- Interval: Create an irrigation schedule with a specified number of days between irrigation.

Program 1 Watering Days WED 5:43:40 PM Schedule Type: 14-DAY Sun Mon Tue Wed Thu Fri Sat Apply: Alternate Reverse All None 14-DAY 31-DAY INTERVAL

Using the Control Dial, operators can individually assign active irrigation days within the 14-day or 31-day time frame. Operators can also select Alternate or Reverse for quick assignment of irrigation days.

The procedure to set Water Days was covered in Chapter 3: Quick Start.

Run Times

The DX3 controller allows the user to individually set a run time for each station.

Program 1 Run Times ED 5:43:40 PM |1-6|7-12|13-18|19-24|25-30|> Station 1 Station 4 00:10 00:10 Station 2 Station 5 00:10 00:10 Station 3 Station 6 00:10 00:10

The procedure to set Run Times was covered in Chapter 3: Quick Start.

Quick Stations

Quick Stations allow the user to quickly enter a run time for a range of stations instead of individually assigning them as done in chapter 3.

This is handy for stations that share similar vegetation type and sun exposure.

Program Hold

A Program Hold can be set, suspending all irrigation activity for that program only for the specified number of days or until manually canceled.

Actively setting a Program Hold for a program will cancel all activity for that program, including non-irrigation activity (see OPT INs next page).

Program 1 Hold 5:43:40 PM Hold Duration 05 (Days) Cancel Hold

To set a Program Hold for all irrigation programs, do so from the Main Menu screen utilizing the Rain Hold feature.

The procedure to set a Program Hold was covered in Chapter 3: Quick Start.

To Cancel a Program Hold

1) so that the Cancel Program Hold field is highlighted (see above).
2) to cancel.

OPT INs

OPT INs essentially tells the DX3 controller to include a Pump or Master Valve in irrigation operation.

Program 1 OPT INs WED 5:43:40 PM Page1 Page 2 Pumps: Master Valves: 1 3 MV/P Start Delay(sec) 010 Inter-Station Delay Yes ISD Delay(sec) MV/P Inter-Station Off Program 1 OPT INs WED 5:43:40 PM Page1 Page 2 Run Time Format HH:MM Irrigation Program Yes Omit by Date No Overlap Protection No Continuous Cycle No Cycle Delay(m) Over-Water Limit Warning Moisture Sensing Yes

Pumps: Check the physical connections on the main DX3 board to determine what numbers to opt in for installed pump/s (if any).

Master Valves: Check the physical connections on the main DX3 board to determine what numbers to opt in for installed master valves/s (if any).

MV/P Start Delay (sec): This is the amount of time, in seconds, that the Master Valve and Pump will wait after a Program's start time before operating. The reason for this is to make sure irrigation channels are open before water starts being pumped and flowing. A pump can be damaged if it begins pumping with no outlet for the water.

Inter-Station Delay: Yes or No. This is the delay between when one station ends irrigation and the next in the program begins. Setting a delay between stations helps to avoid water hammer.

ISD Delay (sec): This is the length of the Inter-Station Delay in seconds.

MV/P Inter-Station: Off or On. Allows a user to select if a MV/Pump is activated in-between station activations in a program. If an operator has opted to use an Inter-Station Delay of thirty seconds, for example, then he/she might want the pump and master valve to stop working during that delay.

Irrigation Program: Yes or No. Defines if the program is a program that runs irrigation (sprinklers, sprays, rotors, etc.) or a non-irrigation program used to control non-irrigation items (lighting, fountain, etc.).

Rain Hold events will only suspend operation of irrigation programs and not non-irrigation programs. Non-irrigation programs will also not be effected by Flow related alarms such as: Main Line Limit, Unscheduled Flow, Monthly

Water Limit, or station flow alarms.

Omit by Date: Yes or No.

If set to Yes, the specified program will not irrigate on days set under the Omit by Date/s command, under Setup-->Omit by Date.

If set to No, any and all Omit by Date/s will be ignored.

Overlap Protection: Yes or No. Overlap protection prevents programs from running on top of each other. This is handy to prevent too many stations from activating at once and also to prevent two programs activating the same station at the same time.

Continuous Cycle: Yes or No. Continuous Cycle runs an irrigation program over and over again during a user-defined Cycle Start and End time. The Cycle Delay is how long the cycle waits, in minutes, before starting again. It is similar to setting Cycle and Soak for an individual station, but for an entire program.

If Continuous Cycle is turned on for a program, it is necessary to go back to the program's Start Times and define the Cycle Start and Cycle End times.

Program 1 Start Times WED 5:43:40 PM Cycle Start / End 06:30AM 06:30PM

A twelve hour water window defined during which Program 1 will run over and over.

Over-Water Limit: Warning or Stop. If the monthly irrigation limit is exceeded, this option determines if the DX3 controller generates an alert or stops watering completely.

Moisture Sensing: Yes or No. Moisture sensing enables data logging and collection of moisture data. A moisture sensor (soil sensor) must be wired properly to the controller. Moisture sensor 1-16 have a 1:1 correspondence with programs 1-16. Only one moisture sensor can be used per program.

Establishment Programs

Programs 15E and 16E are designated establishment programs that expire after a user defined duration. Establishment programs are used for growing seed, when frequent watering is needed at first but not after maturity.

Establishment programs are setup the same as a traditional program, except the establishment start and end dates must be defined.

% Adjust

Setting the % Adjust Value field affects irrigation only for that specific program. For example, if you set a % Adjust value of 50% for Program 1, run times that are set to 20 minutes will only run for ten. Program 2 run times will be unaffected.

Program 1 % Adjust WED 5:43:40 PM % Adjust Value 50

If you set the \% Adjust value to 150\% for Program 2, run times set for 20 minutes will now run for 30. Program 1 run times will be unaffected.

The procedure to set % Adjust was covered in Chapter 3: Quick Start.

Backup Programs 10 & 11

Programs 10 and 11 are utilized as backup irrigation programs when using Laguna central software Advanced Irrigation Management (AIM) or Advanced ET generated Independent Station Control (ISC) algorithms. If an ISC fails to download from central to the controller for more than 24 hours, the controller will run the backup programs irrigation schedules.

It is strongly recommended to utilize Backup programs when using AIM or Advanced ET generated ISCs in order to maintain any Master Valve or Pump association to a station.

Programs 10 & 11 serve as conventional programs if not using AIM or Advanced ET generated ISCs.

Chapter 6: Stations

The Stations command allows the user to:

• define minimal, nominal, and maximum flow and current amounts for every station in a system
• set parameters for Cycle and Soak to reduce water runoff.

Flow

This screen allows the operator to manually set the minimal, nominal, and maximum flow amounts for every station in a system.

Stations WED 5:43:40 PM |Flow |Current |Cycle & Soak Station 002 Minimal Flow 008 Nominal Flow 0010 Maximum Flow 0012 Learn Flow

The operator can manually set the minimal, nominal, and maximum settings for each station, or simply check the Learn Flow checkbox at the bottom of the screen. When the Learn Flow/Current command (chapter 5) is activated, the fields for those stations will be filled in automatically.

Current

This screen allows the operator to manually set the minimal, nominal, and maximum current amounts for every station in a system.

Stations WED 5:43:40 PM |Flow|Current|Cycle & Soak Station Minimum Current 1.00 Nominal Current 1.05 Maximum Current 1.1 Learn Current

The operator can manually set the minimal, nominal, and maximum settings for each station, or simply check the Learn Current checkbox at the bottom of the screen. When the Learn Flow/Current command (chapter 5) is activated, the fields for those stations will be filled in automatically.

Cycle & Soak

Cycle and Soak was developed as a method to ensure the soil absorbs as much of the irrigation water as possible, minimizing water run-off.

Stations WED 5:43:40 PM |Flow|Current|Cycle & Soak Station 002 Cycle & Soak (H:M) Cycle Time (Max) 05:00 Soak Time (Min) 10:00

Imagine the run time for station 2 is fifteen minutes. However, station 2 irrigates a slope with a walkway at the bottom. If the station irrigates for fifteen minutes straight, most of that water will simply run off the hill and onto the hardscape and be lost. Cycle and Soak is a way to eliminate or drastically reduce that waste.

Cycle Time (Max) - This is how long the station will run in "chunks" towards the overall run time. If station 2 run time is 15 minutes, then, according to the settings above, station 2 will irrigate for 5 minute "chunks" until that run time is met.

Soak Time (Min) - Between those irrigation cycles is the soak time in which no irrigation takes place. Water is allowed to absorb into the soil. After the specified “soak” time, irrigation will resume for another Cycle Time or until the station run time is met.

Soak time may be longer than the minimum time specified.

A DX3 will execute irrigation for other stations in a program during a soak time, instead of waiting idle, in order to optimize a user's water window.

Steps

1) to select the desired station. to set.
2) Turn on Cycle & Soak for that station by

Chapter 8: Alerts

The DX3 series controller automatically alerts the operator when problems occur or certain conditions arise. The controller may trigger an alert in response to over 11 different conditions. Each condition is date/time stamped and includes additional information which may be helpful in troubleshooting the problem. Up to 15 alerts may be saved in the controller at one time. The user may delete alerts at any time.

(0) Active Programs (0) Active Stations (2) Alerts A: Power reset 24 (GPM) Expected 0

Some alerts, such as a main line limit violation, require immediate attention as all irrigation activity is condemned until the alarm is cleared.

Most alerts, due to the controller's programming, do not necessitate immediate operator attention. For example, consider a station with a broken head (FLOW UPPER LIMIT warning). Upon detection of this failure, the DX3 controller will:

1. Turn the failed station off.
2. Mark the station as condemned (will not water again until the alarm/warning is cleared).
3. Advance to the next scheduled station in the program.
4. Report the failed station as a warning.

Upon review of the alert, maintenance personnel would repair the problem and then clear the alert at the controller. (Clearing the alert re-enables all irrigation at the station).

Any time an alert is triggered, the DX3 screen displays the alert type.

Anaylzing an Alert

Alerts can be accessed for analysis from the Main Menu.

Alerts and Corrective Action

For all alerts, upon resolution of the specific problem, be sure to CLEAR all alerts at the controller.

Reset

This alert is triggered when the DX3 controller detects AC input power.

Clear the alert at the Setup-->Alerts screen.

High Temperature

This alert is triggered when the main board temperature sensor exceeds a threshold value.

Station Communication Error

This alert is triggered when communication fails between the TM and the specific station output board terminal.

Master Valve High Current

The controller expects a certain current delivered to the Master Valve to trigger operation. If the measured current is greater than the expected current, within the preset tolerances, a High Current alert will be triggered.

Flow Lower Limit and Flow Upper Limit

The Flow Lower Limit and Flow Upper Limit alerts are triggered when the measured flow is either less than or greater than the expected flow, + or - preset tolerances. Both alerts display the station number (Stn:) which was on at the time of the limit violation, the Master Valve (MV1) and/or the Pump, the GPM reading (12) as measured by the flow meter, and the limit value set for the station. Upon detection, the controller automatically terminates irrigation on the station and advances to the next station in the program. Condemned stations will not irrigate again until the warning has been cleared.

Flow Lower Limit alert may be caused by:

• A malfunctioning valve
• Incorrectly established individual station limits
• Large variations in static water pressure
- Improper regulation
- Line impediments

Flow Upper Limit alert may be caused by:

• Stuck valve (from previous station)
- Broken pipes/heads
- Unreasonable or inaccurate individual station limits
• Large variations in system water pressure

Flow Alert Troubleshooting

1. If station limits are suspected, manually turn each station on and observe the

nominal GPM readings.

1. Compare the GPM reading with the limit setting to insure that adequate margin exits (typical: 50% below nominal).

Water Limit

The controller has exceeded its monthly watering allocation (set in the Setup-->Flow-->Flow Options screen). If the program has been set up to stop watering, no further irrigation will occur until day one of the next month. If the program has been set to provide an alert only, and the alert is cleared, then this alert will reappear (though watering continues).

Corrective Action

The Monthly Limit can be increased.

Max Station Limit

This alert is triggered when the controller has attempted, either through manual operation or scheduled operation, to activate more than sixteen stations at one time.

Corrective Action

1. Try to locate the "overstacked" schedule program.

2. If the alert was triggered by an overstacked manual operation, for example setting too many simultaenous stations to execute at once, there is nothing to be done other than not to exceed the simultaneous station limit again.

Start Delay Overlap Protection

This alert is triggered when the DX3 attempts to start a second program when the first program is still active and Overlap Protection (under Program-->OPT INs) is active for that first program.

Start Block Max Stations

This alert is triggered when the DX3 controller attempts to operate more than the number of maximum stations at one time.

Start Block Program Running

This alert is triggered when the operator has programmed the DX3 controller to start a program that is already running. For example, Program 1 starts at 6am every morning and runs for three hours. At 8am, the operator attempts to manually run Program 1 from the Manual menu. An alert is generated.

Satellite Offline / Online

This alert is triggered when the satellite loses / reestablishes contact with the submaster.

Hardware (HW) Communication Failure

Set on submaster to indicate it lost communication with a satellite not configured for Flow Max.

FlowMax (FM) Communication Failure

Set on submaster to indicate it lost communication with a satellite configured for Flow Max.

FlowMax Stop Water

This alert is triggered when the controller is in a stop watering state.

FlowMax Multiple Flow Meters

This alert is triggered when the specified flow meter is defined on more than one controller in the Flow Max group. DX3 will add flows together for multiply defined flow meters.

FlowMax Multiple Pumps

This alert is triggered when more than one controller in the flow max group has the specified pump defined. DX3 will operate all multiply defined pumps in tandem.

FlowMax Multiple Master Valves

This alert is triggered when more than one controller in the flow max group has the specified master defined. DX3 will operate all multiply defined masters in tandem.

Current Upper / Lower Limit

This alert is triggered when actual current was above maximum current or below the minimum current allowed.

Main Flow Limit

This alert is triggered when flow exceeded main line flow limit.

Unscheduled Flow Limit

This alert is triggered when flow exceeded unscheduled flow limit.

Station Short Circuit

This alert is triggered when decoder reports short circuit.

Auto Limits Aborted

This alert is triggered when auto limits process was terminated before completion.

FlowMax Communication Restored

Flow Max configured satellite triggers this alert when it has established or restored communication with the Submaster.

FlowMax Station Advance

This alert is triggered when the satellite is a FLOWMAX participant and received station advance from a FLOWMAX related alarm.

Power ON

This alert is triggered when the controller resets and restarts after a power disruption.

Daily / Hourly Rain Limit

This alert is triggered when rain exceeded daily / hourly rain limit.

Wind Exit / Enter Contition

This alert is triggered when wind was below / above limit for prescribed time, wind shutdown is ended / started.

Upload Request

User has indicated they wish controller settings to be uploaded by the central.

Clear All Alerts

Clearing this alert will clear all alerts, and all underlying flags that may have been orphaned if alerts were overwritten.

Station Open Circuit

This alert is triggered when decoder reports open circuit.

Station Over Current

This alert is triggered when decoder reports over current.

Decoder Ports Exceeded

This alert is triggered when decoder reports too many ports on.

Decoder No AC Voltage

This alert is triggered when decoder reports no AC voltage.

MV Current Upper Limit

Indicates Master Valve current draw exceeded the maximum allowed. Alert will display the measured current and maximum limit.

MV Current Lower Limit

Indicates Master Valve current draw was below the minimum allowed. Alert will display the measured current and minimum limit.

Pump Current Upper Limit

Indicates Pump current draw exceeded the maximum allowed. Alert will display the measured current and maximum limit.

Pump Current Lower Limit

Indicates Pump current draw was below the minimum allowed. Alert will display the measured current and minimum limit.

FLOW MAX Lower Limit (Submaster Only)

Indicates actual flow was below minimum flow allowed. Alert will display measured flow and lower limit.

FLOW MAX Upper Limit (Submaster Only)

Indicates actual flow was above maximum flow allowed. Alert will display measured flow and upper limit.

Chapter 9: Rain Hold

There are several ways in which a DX3 can be placed in Rain Hold. This chapter will focus on a globally set Rain Hold. For a local program level Rain Hold, please refer to Chapter 6, Program Hold. A global Rain Hold can be set manually via Main Menu -> Rain Hold. When activated, Irrigation Rain Hold will suspend irrigation activity for the specified number of days (or until canceled).

Additionally, a Rain Hold can be set via a tipping bucket rain sensor, rain switch sensor, freeze switch sensor and/or Laguna central software. A sensor related Rain Hold event will be displayed at the bottom of the screen. For connecting sensors to a DX3 controller, see Appendix B.

Irrigation Rain Hold WED 5:43:40 PM Set 00 Day(s) Set Until Canceled Cancel Hold Hold Status: not set Sensor Related Rain Off: No sensor related holds exist

Non-irrigation programs (such as lighting or for a fountain), are NOT placed on a Rain Hold with this command).

To Place a Rain Hold for a specified number of days:

1) Enter Set Day(s) field.

2) Change to desired number of days.

3) Set value.

4) When done, press T R.

Chapter 12: Troubleshooting

This chapter describes the resources available to troubleshoot field wiring problems, broken heads, pipes and mainlines, AC power problems, monitoring of water usage, and more.

In order to take full advantage of all the capabilities of the DX3 controller as a maintenance tool, refer to the following manual sections for operational information and proper setup:

• Flow Monitoring: See Appendix B: Flow Meters
• Broken field wiring, short circuits, and faulty valve solenoids: See Appendix C: Current Monitor

Communications Wiring Issues (Satellite to Satellite)

All alerts are systematically retrieved and recorded by the Central Control Computer. Central software has reporting tools to comprehensively sort, organizer and filter alerts by various parameters.

DX3 satellite groups use a daisy chain configuration, that will result in failed communication to all downstream devices at the point of failure. Here is an example:

A FLOWMAX group is hardwired together consisting of four satellites

Submaster_001-00 <-> Satellite_001-01 <-> Satellite_001-02 <-> Satellite_001_03

If the communication line is severed between satellite 001-01 and 001-02, all satellites downstream of 001-01 lose communication with the submaster. In this case, that would be Satellite_001-02 and Satellite_001-03. This would result in alerts at the submaster for loss of communication with the given satellites and an alert at satellites 001-02 and 001-03 for loss of communication with the submaster.

Submaster

If the submaster loses communications with one of its hardwired satellites, a hardwire (HW) communications failure is detected (below). An entry is made in the submaster's alert list.

Alerts WED 5:43:40 PM Alert #:001 of 003 Type: W:HW Comm Failure Recorded: 06/25/17 17:42 P/MV: --- Stn: --- Limit: Satellite 2 Press 'A' to Clear Alert

Satellite

When a satellite loses hardwire communication, it is "off-line". When communication is re-established, it is "on-line" (see Alert below). When a satellite becomes off-line or on-line, an entry is logged in the satellite's alert list.

Alert #:001 of 004 Type: A:Power ON Recorded: 06/25/17 17:41 P/MV: --- Stn: --- Limit: 2:28 m:s off Press 'A' to Clear Alert

Communication Wiring Issues (Satellite to Station):

For both conventional and 2-wire decoder stations, if a satellite cannot communicate with a given station, a specific alert will be generated.

Alert #:001 of 003 Type: Comm Alert Stn 70 Recorded: 06/25/18 17:42 P/MV: --- Stn: --- Limit: --- Press 'A' to Clear Alert

For conventional stations, verify the cable connection to the output board responsible for that station. Verify the output board has the proper power and status LEDs illuminated. Under the "Review -> About" menu, verify the Opt. FW for the given output board is displayed. If the cable connection is good but the power/status LEDs are not illuminated correctly, or the Opt. FW cannot be read, contact a Rain Master service representative.

For 2-wire decoder stations, verify the cable connection to the 2-wire output board. Verify the 2-wire output board has the proper power and status LEDs illuminated. Verify the field wiring connection to the 2-wire output board. In the field, check the field wiring and connections to the given station.

Diagnostics

The DX3 controller utilizes several advanced tools for communication troubleshooting. These tools are used by RMIS service personnel to diagnose and correct field communication problems. These tools are detailed in Chapter 7: Reports and Diagnostics.

Multiple Stations Do Not Water

(Many station lights on)

Short Circuit Shutdown 86

Automatic Program Does Not Start 87

Flow Sensor Reading Always Zero 89

Multiple Stations Do Not Water

(Many station lights on)

Station LED for the suspect zone turns on, and other station LEDs turn on.

If a zone does not water but that station's red LED light turns on as well as other various LEDs for other stations, the field "common" wire for those stations is not connected (floating) to the controller. Check the field wiring common connection at the controller and at the field junction where they may be tied together. Check for continuity of the common line from the controller to the field valve.

The following schematic diagram illustrates a sample wiring configuration of four solenoids connected to station outputs:

Controller Station Output Board

10 9 Co 8 7 6 5 4 3 2 1 Co

The solenoids connected to station outputs 1, 4, and 7 share one common line return to the station output board. Station #9 is shown as a normal operating station, which is connected independently from the other stations (not sharing the common connection).

If the common line is broken or open (as shown by the cross marks), current does not flow and the solenoid is not energized. This condition is possible whenever groups of field valve wiring configurations are tied together to one common return line.

In the example above, if station 1, 4 or 7 are activated, the station LEDs for 1, 4 and 7 will all illuminate but the solenoids will not energize.

Note: Station 9 LED will not be illuminated and solenoid will not be energized because station 9 does not share a common with station 1, 4 or 7.

Short Circuit Shutdown

A short circuit shutdown event is generated when the total cumulative current draw of all conventional outputs (stations, MV's and Pumps) measured by the MV/Sensor board exceeds 2.75Amps. An alarm will be generated and the MV/Sensor board will sever the common connection to all conventional outputs, preventing them from energizing. The severed common connection can be quickly diagnosed by the illumination of the shutdown LED (reads 'OFF' on main board cover).

1 2 3 1 2 MV PUMP OFF 24VAC 12V 5V 3.5V COMMON - - - 24

Once the alarm is cleared, the MV/Sensor board will reset the common connection.

Note: In the event of a short circuit shutdown, no station LEDs will illuminate if activated. If a MV or Pump is activated, all MV and Pump LEDs will illuminate in the same manner as station outputs sharing a common connection will, as described in the previous section.

Control Devices

(Rain Sensors, Freeze sensors, Etc.)

Many commercial sensor devices available in today's market take advantage of the common ground configuration to control watering operations. Devices such as rain sensors, freeze sensors, moisture sensors, etc. employ a control system which interrupts the common ground line of watering stations to control the shutdown of stations.

These devices have inherent limitations:

1. They exhibit "contact bounce" or jitter when the on/off threshold is reached. This may have adverse affects on pump systems.
2. Since they interrupt common lines, non-irrigation programs such as lighting programs are also affected.
3. It may be difficult to identify/interrupt the "common" wire if multiple commons come in from the field.

DX3 flow features/capabilities include:

• Display of instantaneous flow rate in gallons per minute (GPM) for all three meters as well as total (Flow #1 + Flow #2 + Flow #3). Flow rates are updated every ten seconds.

• Display of monthly flow accumulations in gallons for all three flow meters as well as total (Flow #1 + Flow #2 + Flow #3). Flow accumulation in gallons is updated every minute.
  • Automatic termination of watering based upon flow limit violations:

• Main line flow rate for controller (GPM)
  • Maximum flow rate per station (GPM)
  • Minimum flow rate per station (GPM)
  • Maximum flow accumulation per month (gallons)
  • Unscheduled flow rate for controller (GPM)

- Automatic condemnation and reporting of stations violating flow limits. Alert information is provided in Chapter 8: Alerts.

• Automatic establishment of station upper and lower flow limits (Learn mode).

Flow Sensor Installation Instructions

The plastic cover of the DX3 main board shows all inputs and terminal polarity. To install a Irritrol or Rain Master flow meter:

Flow Sensor Overview

To establish flow limit checking either on a controller or individual station basis, verify the following:

• Flow meter is installed properly.
• Correct Offset and K values are entered.
• Station Upper Limits have been established. See "Max Flow Limit".
• Station Lower Limits have been established. See "Min Flow Limit".
• Main line flow limits have been established. See "Main Flow".

• Total Monthly Flow has been set. See "Flow Options".

- Unscheduled Flow Limit has been defined. See "Unscheduled Flow Limit".

- Upper and lower limit checking is enabled. See "Enable/Disable Limit Checking".

- The appropriate flow limit check delay has been established. See "Delay Limit".

- Selection of at least one of the three flow meters. See "Setup -> FLOWMAX, devices connected to this clock."

If all above steps are completed, typical accuracy values of flow sensor readings are approximately within 1%.

Flow Sensor Offset and K Values

Each flow meter installation must include entry of the "offset" value and "K" values for proper calibration of the meter. The DX3 controller supports the complete line of Rain Master and Irritrol-branded flow sensor (DI & CST). Flow Sensors may be either conventional and/or decoder type. The controller can only have 3 in total.

Flow Limit Checking

To perform limit checking, the controller computes a Gallon-Per-Minute (GPM) flow rate based upon the total gallons used in the previous 60 seconds.

Limit checks are performed on the following:

• Station upper limit
• Station lower limit
• Main flow limit
  • Total monthly flow limit
• Unscheduled flow limit

Station limits can be automatically established by the controller or manually entered.

Station Limit

It is possible to enter a station flow limit by manuall entering the station limit, as described in Chapter 7 or 11, or have the controller automatically set the limit during a "learn" process as described in Chapter 5. Ensure the flow check delay is set to a high enough value to allow for adequate hydraulic settling time for the flow meter readings to stabilize before obtaining the nominal flow rate.

The controller compares the flowmeter reading to the station limit. If the meter value is larger than the station upper limit, a high flow alert is raised. If the meter value is smaller than the station lower limit, a low flow alert is raised.

The suggested upper limit flow rate should be set to the nominal flow rate for the station +20%. The suggested lower limit flow rate should be set to the nominal flow rate for the station -20%.

If water pressure varies greatly, upper station limits should be increased.

Main Flow Limits

Enter the Main Flow Limit, as described in the Main Flow procedure in Chapter 5. The controller compares the flow meter reading to controller/main line station limit. If the meter value is greater than the limit, an alert is generated.

The system default value for controller/main line limits is 500 GPM.

The Main Flow upper limit should be set higher than the total of all simultaneously "on" stations. However, this limit should be lower than the anticipated flow rate from a main line break.

In Flow Max systems, the total water consumption of all participating controllers is calculated into the Main Flow limit.

Total Monthly Flow Limit

Enter a maximum monthly flow limit, as described in Chapter 4. The controller compares the accumulated monthly flow to maximum monthly flow limit. If the accumulated flow is greater than the limit, an alert is generated.

The system default value for maximum monthly total is 9,999,999.

If the monthly limit is exceeded, there are two options available, STOP and WARNING. See Chapter 5: Program Entry for details on selecting each option.

If the STOP option is selected, the problem is reported in the alert list and watering stops.

Watering is restarted when:

• the limit is changed to a larger value
• the program option is changed to Warning
- a new month begins

If the WARNING option is selected, an alert is reported in the alert list and watering continues.

Unscheduled Flow Limit

Unscheduled Flow Limit is defined as any water flow that is not programmed or under the control of the controller. If a water flow is greater than the limit, the flow check delay has been met, and no stations are on, the controller will shut down the water supply until the condition is corrected.

Unscheduled Flow conditions may be due to broken water lines, defective valves, faulty solenoids, etc.

The Unscheduled Flow procedure is given in the Controller Setup section of Chapter 4. The default limit is 0 GPM.

Enabling and Disabling Flow Limit Checking

Once the station limits have been established, the flow limit checking (upper and lower limits) may be enabled or disabled. When upper limits have been enabled, all station upper limits will be enforced. When lower limits have been enabled, all station lower limits will be enforced. See Chapter 4 for the steps to enable or disable station flow limit checking.

When limits are disabled, no limit checking is performed. However, the GPM flow, total monthly flow readings, the Monthly Limit, Main Line Limit, and unscheduled limits are all unaffected.

Delaying Flow Rate Limit Checking (Flow Check Delay)

Due to drainage of water lines, the initial flow rate for a station may be much higher than the station steady state condition. To prevent erroneous station fault detections, the controller delays a period of time after a station is turned on before making flow rate limit checks. This delay may be set from 2 to 6 minutes.

The system default for delay of limit checking is two (2) minutes.

To establish the proper delay, monitor the GPM flow rate for each station in the irrigation program(s).

Observe which station takes the longest time for its GPM rate to "settle." Round this time period to the next minute and use this rounded value as the flow rate limit check delay.

Limit Checking with Two or More Flow Meters

When two flow meters are used, you may select which meter is used for limit checking. Alternately, you may check the total flow from both meters. Do this by:

1. Under Setup --> Flow --> Flow Sensors, the Include in Total Flow setting must be set to YES for both meters.

In order for flow values to be tracked, the "Devices Connected To this Clock" option must be selected under the Setup -> FLOWMAX.

Flow Limit Violations

When a Flow Limit Violation is Detected

Upon detection of a flow limit violation, DX3 performs the following actions:

1. Terminate irrigation

- For a faulty station, immediate termination of irrigation for that station. The program will automatically advance to the next station in the program.

- If a main line fault is detected, immediate termination of all irrigation programs. The Normally Open (N.O.) Master Valve terminal is energized with 24 VAC. Any and all future automatic irrigation will not occur until this warning is cleared from the controller.

- If the monthly watering allocation has been exceeded, immediate termination of all irrigation on a per program basis occurs.

- If an unscheduled flow condition is detected, the Normally Open (N.O.) Master Valve terminal is energized with 24 VAC. Any and all future automatic irrigation will not occur until this warning is cleared from the controller.

1. Entry of the problem in the Warning/Report list.

2. All faulty stations are added to a "condemned" station list. No watering will occur until the problem is corrected.

To remove a station from the condemned list, delete the corresponding alert.

Examples

Overflow in Controller/Main Line Break

Assume the maximum controller flow rate is 500 GPM. A main line break occurs while attempting to water station 7. The break results in a flow of 510 GPM. The following alert is displayed, as well as the station number and GPM reading:

(0) Active Programs (0) Active Stations (1) Alerts A: Main Line Limit Exceeded 0 (GPM) Remote: 0~

If we were then to drill down into the alert, we could see more information about this condition. All irrigation is suspended until the alert is cleared. In addition, Normally Open Master Valves are energized.

Alert #:001 of 004 Type: A:Main Line Limit Exceeded Recorded: 08/09/17 13:33 P/MV: P1 M1 Stn: 1,2,3 Limit: 510 gpm Alarm Number: 5 Press 'A' to Clear Alert

The 'Limit' number above is the actual flow value at the moment the alarm was triggered.

This situation may also be caused by a valve that fails to close.

Station Overflow

Assume station 2 has an upper limit of 300 GPM. A broken line occurs, resulting in a 400 GPM flow. Resulting action in this example will be the generation of a High Flow alarm, station 2 will be condemned from any current or future irrigation, and the alarm is cleared.

Alert #:002 of 004 Type: A:Maximum Flow Recorded: 08/09/17 13:33 P/MV: P1 M1 Stn: 3 Limit: 50 actual: 65 gpm Press 'A' to Clear Alert

Station Under Flow

Assume station 2 has a lower limit of 100 GPM. The line to station 2 is clogged, resulting in a flow reading of 53 GPM. Resulting action in this example will be the generation of a Low Flow alarm and station 2 will be condemned from any current or future irrigation and the alarm is cleared

Alert #:002 of 004 Type: A:Minimum Flow Recorded: 08/09/17 13:33 P/MV: P1 M1 Stn: 3 Limit: 100 actual: 53 gpm Press 'A' to Clear Alert

Monthly Water Limit Exceeded

The controller has exceeded its monthly watering allocation. This problem cannot be cleared from the report until the water limit is set to a higher value or until a new month begins. Irrigation will continue uninterrupted for non-irrigation programs or irrigation programs that have selected the "Warning" option for monthly limit (see Setup menu, chapter 5). Irrigation programs that have selected the "Stop" option, however, will be suspended until the alarm is cleared.

Alert #:002 of 004 Type: A:Monthly Limit Exceeded Recorded: 08/09/17 13:33 P/MV: M1 Stn: --- Limit: 482 gpm Press 'A' to Clear Alert

Multiple Stations with Non-Overlap Protection

The DX3 controller allows the user the capability of turning "on" several stations simultaneously. When flow meters are used in this environment, the individual station limits are summed and compared to the total flow rate. Therefore, you must set up limits for each station to insure that flow limit checks are performed properly.

Example:

Assume the upper limit for station 1 is 80 GPM and the upper limit for station 2 is 50 GPM. If both stations are on, the controller adds these limits. A problem is reported if the flow exceeds the total of 130 GPM (80 GPM + 50 GPM).

Appendix C: Current Alarms Within a Conventionally Wired DX3 System

Note: This document pertains to Rain Master DX3 submasters, DX3 FLOWMAX groups and mixed DX3 and DX2 FLOWMAX groups activating conventional station types. This document presents scenarios on how a DX3 system measures and responds to current related alarms. For details on how pure DX2 FLOMAX groups measure and respond to current related alarms, please refer to the DX2 user manual.

Overview: A DX3 controller has the capability to measure master valve (Mx), pump (Px) and station (Sx) current and compare against minimum and maximum limits. A user can globally enable/disable current limit checking for a controller via Laguna or the controller setup menu.

If current limit checking is enabled and the current measured for an output is below the minimum or above the maximum, an alarm is generated, and the output is condemned from future irrigation until the user clears the associated alarm. If multiple outputs are ON during the violation, irrigation is suspended (valves are deactivated, and program runtimes continue to decrement), a diagnostic process is started to determine the offending station(s) and alert(s) are generated for each output in violation, condemning them from future irrigation until the user clears the associated alarms. A diagnostic will only be ran once for a given group of stations and start time (not working as of 7/27/18). After the diagnostic process has completed automatic irrigation operations are resumed, but manual operations are terminated.

Each over/under current alarm for a MV, Pump or station will contain the timestamp of the violation, the measured current and the limit value compared against.

Unlike DX2, a DX3 will perform limit checking on Master Valves and pumps if current limit checking is enabled and condemn if necessary.

All station, Master Valve and Pump related over/under current condemnations (alerts) must be cleared for a given output, otherwise no activation will occur. A DX3 controller will block a program from starting if it utilizes a condemned Master Valve or Pump. Manual operations will activate any output that is not condemned.

Current alarms are only generated at the satellite activating the output, all other FLOWMAX participants will be unaware of the alarm and will attempt to run their automatic programs.

All satellites will report measured current and compared limit for each under/over violation. Laguna will report the measured value, satellite compared limit and Laguna max, min and nominal limits for station violations, but only the measured value and satellite compared limit for MV's and Pumps.

Current Alarm Formats as Reported by Laguna:

1139 - Actual current is above maximum allowed current: MVx: actual current exceeded allowed current
1141 - Actual current is above maximum allowed current: Px: actual current exceeded allowed current
1120 - Actual current is above maximum allowed current: Sx: actual current exceeded allowed current ,
1005 (DX2) - Station Current too high: Sx: Station electrical current too high ,
1004 (DX2) - Station Current too low: Sx: Station electrical current too low ,
1140 - Actual current is below minimum allowed current: MVx: actual current below minimum allowed current
1142 - Actual current is below minimum allowed current: Px: actual current below minimum allowed current
1121 - Actual current is below minimum allowed current: Sx: actual current below minimum allowed current ,

Example Scenarios:

Result 1 - DX3 submaster 001-00 suspends irrigation (valves are deactivated, and program runtimes continue to decrement) and starts diagnostic process.

DX3 submaster 001-00 activates M1, verifies current is in range, and deactivates M1.

DX3 submaster 001-00 activates P1, verifies current is in range, and deactivates P1.

DX3 submaster 001-00 activates S1, verifies current is above maximum allowed, and deactivates S1. DX3 submaster 001-00 raises alarm 1120 "Station Maximum Current" and condemns S1.

DX3 submaster 001-00 resumes automatic irrigation operation of program 1, for none condemned stations. Manual or automatic operations will not activate S1 until alarm is cleared.

Scenario 2 - DX3 submaster 001-00 begins automatic irrigation operation of program 1, by activating MV1, Pump1 then station 1. After station 1 is activated the measured current exceeds the maximum allowed current.

DX3 submaster 001-00 activates P1, verifies current is in range, and deactivates P1.

DX3 submaster 001-00 activates S1, verifies current is in range, and deactivates S1.

Appendix D: Setting Up a FLOW MAX System

Flow Max is a unique feature specifically designed to manage multiple DX3 controllers which share a common water source. Flow Max systems intelligently share resources and manage operations for satellites utilizing a single point of connection (POC). The shared resources may include up to two common pumps, up to three Flow Meters, and up to three Master Valves.

Figure D-1: Flow Max Hardwire Configuration illustrates a typical installation.

The Flow Max feature is not applicable for controllers which have exclusive use of its water source (as in, one point of connection (POC) per controller). Please refer to Appendix B: Flow Meters whenever flow and flow control is required for a single controller installation.

Flow Max utilizes the intelligence of DX3 field satellite controllers to provide the following features:

• Operation of shared Master Valves, Pump or Flow Meters across controllers without the need for peripheral relays or complex wiring.
• Shared devices may be wired in the conventional fashion to the nearest controller.
• Dynamic adjustment/validation of station flow limits as stations turn on and off anywhere in the system.
  • Detection of system main line breaks.
  • Detection of system unscheduled flow.
• Ability to read the flow GPM rates at any of the Flow Max participant

controllers.

- Automatic establishment of flow limits and current limits for all the controllers in the system.

- Automatic system protection for the shared pump in partial power outages or communication failures.

- Automatic generation of diagnostic system warning messages at each Flow Max unit.

• Dynamic real time monitor shows system status at all times.

Overview

A Flow Max system is comprised of a number of identical DX3 controllers (typically 3 to 5) with the first controller set up as the submaster and the remaining units set up as satellites.

Controllers that share any Pump, Master Valve or Flow Sensor are defined as Flow Max participants. As Flow Max participants, the DX3 controllers must be part of a serial hardwire configuration. Controllers that are not Flow Max participants may reside on the hardwire link but must be defined as nonparticipants.

The serial hardwire configuration requires a communications cable (EV-CAB-COM).

Flow Max provides a means to detect station flow limits and main line breaks within design and programming limitations.

All controllers participating within a Flow Max system must be programmed as Flow Max participants from each of their respective control panels.

Submaster

The Submaster controller in the Flow Max group is the watchdog for the entire group. It monitors all participant device operations such as pumps and master valves. It also issues corrective action for flow violations, maintains the communication link status with the Central, and accumulates all flow related data. The Submaster allows the user to review all pertinent shared device information from its control panel. The user can also monitor real time activity such as measured flow, upper and lower limit changes as stations transition, as well as flow delay status.

The Submaster allows flow limits and current limits for each station of all participant controllers to be established automatically from one location.

Devices

The devices in a Flow Max system are defined as follows:

• Master Valves 1, 2, and 3
- Pumps 1 and 2
• Flow Meters 1, 2, and 3

Flow Max allows any participant controller to utilize a shared device. When a Flow Max participant program reaches its "Start Time," the Submaster initiates a command to turn the device on. The device will remain on provided there is at least one program running that has been set up to share the use of the device.

Shared devices may be connected to any Flow Max participant controller. Each device connection is made to one and only one controller. All other participant controllers that share the use of the device must be programmed at the respective controller to select the appropriate option.

The Master Valve, Pump, and Flow Meter devices are physically connected to the respective controller Master Valve Power Board. Flow Meter installation instructions are included with the optional Flow Sensor kit.

Flow Sensors

Flow sensor operation must include the calibration factors of "K" and "Offset" values for accurate calculations. These values are required to compensate for the differences between pipe size and flow sensor used. Complete tables on K and Offset values are given in Appendix B: Flow Meters.

The satellite controllers that are physically connected to flow sensors must have the "K" and "OFFSET" values for the particular flow sensor programmed.

Each point of connection for a MV, Pump or Flow Sensor must be defined at the controller it's connected too. The selection is made under menu Setup -> FLOWmax, "devices connected to this clock".

Setup FLOWMAX WED 5:43:40 PM FLOWMAX Participant (Submaster always Flow Max Partic) Devices Connected to this Clock: Pumps: Master Valves: 1 2 3 Flow Sensors: 1 2 3

Flow Check Delay

The Flow Check Delay provides a specified amount of time before any limit comparisons or corrective action is taken by the system. This allows water lines and pressures to stabilize after station turn on and turn off transitions.

The system has the default flow check delay of two minutes.

When a station turns on, flow measurement begins immediately; however, the limits will not be checked or reacted upon until the first reading after the flow check delay has completed. Keep in mind, that the more station transitions that occur within the group of Flow Max participants, the more limits will go un-checked.

Main Line Limits

For any number of controllers within a Flow Max group, there will only be one Main Flow Limit. Remember that the main flow limit must be higher than an expected flow under normal operation yet low enough to react when a main break line occurs.

Main Line Limit settings must be made at the submaster for a FLOWMAX group, regardless of where the point of connection is. Each participating controller in the FLOWMAX group will be held to submaster Main Line Limit settings. (Same for

Unscheduled flow.) Main Line Limit settings set at satellites in a FLOWMAX group will be ignored.

Flow Max Limitations

Although the number of controllers in a Flow Max system is not limited, the higher the number of participants, the less control there is to detect problems.

Assume a total of five controllers in a Flow Max group with all five controller programs running simultaneously. Each of the five programs operating has stations that under normal conditions use 100 Gallons Per Minute to irrigate. Each station allows for a 10% Upper Limit Tolerance. With a 10% tolerance, a station normally using 100 GPM would be allowed a maximum flow of 110 GPM before causing an alarm. With five stations operating under the same conditions, Flow Max, which sums all limits, will allow a maximum flow of 550 GPM before causing an alarm for a station upper limit violation. This means that a broken head would require a 50 GPM measurable difference before causing an alarm, not a 10 GPM difference, which would be the case if only one station had been operating.

Under the conditions above, normal operating flow would be 500 GPM with station limits allowing up to 550 GPM. The main flow limit must be higher than 550 GPM. The question is, does a main line break yield more than 550 GPM? That's where programming and scheduling can accommodate the ability to keep the main limit within an amount detectable by a real break.

Physical Configuration

The Hardwire Link provides the communication among all controllers of a standard irrigation system and/or a Flow Max system. All units are connected in a series configuration using direct burial EV-CAB-COM twin axial cable (sold separately). The Hardwire Link provides reliable communication among the controllers at distances up to several thousand feet.

Figure D-1: Flow Max Hardwire Configuration illustrates a typical wiring configuration for a 3 controller system.

System configurations that include the Central Control Computer will require the submaster controller to operate with either a wireless communication board (radio, cellular, WiFi), a direct serial connection, or and Ethernet connection.

Figure D-3: Detailed Master Valve and Station Connections

Master Valve/Pump Configuration

The Master Valve or Pump may be physically connected to any controller of the system, which is then shared by the remaining controller units. Any given valve/pump may be physically connected to only one controller.

The Master Valve Power Board supplies the power and control for the Master Valves and Pump. Every controller is equipped with this board assembly, providing the ability to connect any given valve/pump to any controller. Connections are made to the screw terminals as depicted in Figure E-3. One wire of the valve/pump connects to its associated terminal and the other (common) wire connects to the COM terminal.

Flow Max Setup Procedure

The following section details the programming required in order to setup a Flow Max configuration. Programming must be performed at all controllers that will be part of the Flow Max system.

A typical Flow Max setup includes the following:

Submaster:

• Submaster Address Entry
• Participant Selection / Devices Connected to this Clock
• Include in Total Flow
• Flow Meter K and Offset Values (if connected to this satellite)
  • Station Number and Valve/Pump Assignments
  • Unscheduled Flow Limits
• Main Line Limit
  • Monthly Limit
• Flow Limit Checking

Satellite (Non-Participant):

• Non-participant selection

Satellite (Participant):

• Participant selection /Devices Connected to this Clock
• Include in Total Flow
• Flow Meter K and Offset Values (if connected to this satellite)

This procedure utilizes the configuration depicted in Figure D-1: Hardwire

Configuration with a submaster address of 1-0. The figure illustrates a system consisting of three controllers, a Pump, one Master Valve and one 2-inch Flow Sensor. The Pump is physically connected to the submaster. The Master Valve and Flow Sensor are physically connected to satellite with the address 1-1. Table 1: Flow Max Sample Worksheet lists the parameters for each controller.

Submaster Setup Procedure

1. Check the FLOW MAX Participant checkbox.
2. Using the Control Dial, select the devices which are connected to this Clock. This includes up to two pumps, three master valves, and three flow sensors. For this example, select Pump 1.

Selections made here will allow flow tracking and statistical gathering for reporting and diagnostics.

This completes the Submaster Setup procedure from the satellite.

Flow Max Flow Limits

In a Flow max system, the settings that reside in the Submaster (regardless of point of connection) will control Main Line Limit, Unscheduled Flow Limit, Flow Check Delay, Monthly Limit, and Flow Checking Enabled. The total GPM for all participating controllers is calculated into the overall Main Line Flow Limit value. The Main Line Flow Limit is entered at the submaster controller only. For any number of controllers within a Flow Max group, there will only be one Main Line Flow Limit.

Remember that the Main Line Flow Limit must be higher than an expected flow under normal operation yet low enough to react when a main break occurs.

Set the Main Line Flow Limits

1. At the submaster controller, go to Setup-->Flow-->Flow Options.
2. Use the Control Dial to enter the appropriate Main Line Limit value.

Remeber to have the Monthly Limit, Flow Check Delay, and Flow Checking enabled.

Satellite Controllers

The remaining two Satellite Controllers in Figure D-1 may be configured to either of the two following options:

• Non-participant Satellite - NOT part of the Flow Max system.

- Participant Satellite - Part of the FlowMax system utilizing one or more shared devices.

For a Non-participant Satellite

1. At the non-participant satellite, go to Setup-->Flow Max.

2. Be sure FLOW MAX Participant is unchecked.

This step does not apply to our sample procedure.

For a Participant Satellite, not directly connected to shared device/s (Figure D-1, Satellite 1-2)

1. At the participant satellite, go to Setup-->Flow Max.

2. Be sure FLOW MAX Participant is checked.

3. Entering K and Offset values is not required for this satellite.

Participant Satellite, directly connected to shared device/s (Figure D-1, Satellite 1-1)

1. At the participant satellite, go to Setup-->Flow Max.

2. Be sure FLOW MAX Participant is checked.

3. Select the devices that are connected to this clock. In this example, that would be Master Valve 1 and Flow Sensor 1.

4. Go to Setup-->Flow-->Flow Sensors. Enter K and OFFSET values.

Setup Flow Sensors WED 5:43:40 PM Sensor 1 | Sensor 2 | Sensor 3 Sensor 1 Type FS-B100 Sensor Name ? K Factor 00109 Offset 0027 Include In Total Flow YES Connection Type Decoder

For further information on K VALUE and OFFSET, refer to Appendix B: Flow Meters.

1. Be sure Include in Total Flow is set to YES.

Repeat the programming steps above for any remaining satellites as necessary (as in, not part of this example).

Once all the participants have been programmed with the Flow Max configuration data:

- Program each satellite with the desired irrigation program(s).

Insure the program(s) have been set up properly for usage of a Master Valve and/or Pump.

- Flow limits must be established for all stations in the system. Flow limits can be established using the Learn Flow/Current feature.

This completes the Setup procedure for the satellite controllers.

Flow Max Diagnostic Tools

Real Time Flow Monitor

A Real Time Flow Monitor is available at the submaster controller of a Flow Max system. This tool provides a wealth of information about the operational status of the system. The real time monitor can be started and run in the background as the system is running.

Procedure

Go to Reports-->Water Usage-->Flow Rates.

Water Usage WED 5:43:40 PM |Water Use Flow Rates| Local Remote Total Flow 1 0 0 0 Flow 2 0 0 0 Flow 3 0 0 0 TOTAL 0 0 0 Min Flow 0 0 0 Expected 0 0 0 Max Flow 0 0 0

The Flow Rates screen updates continuously and displays:

• Flow from Flow Sensors.
• Total Flow
• The dynamic flow upper limit (UL), changes whenever stations at any controller transition On or Off
• The dynamic flow lower limit (L), changes whenever stations at any controller transition On or Off
• The status of whether the submaster is in Flow Delay (FD) mode. If “FD” appears on the second line of the display this indicates that flow delay is in effect, hence limits are not being checked. The absence of "FD" from the display means that the measured flow is being checked against the displayed limits.

The Real Time Flow Monitor is a useful tool for verifying that the proper flow delay has been programmed for the system. Flow readings should stabilize a minimum of 20 to 30 seconds prior to the "FD" removal from the display. This should provide adequate margin when programming this parameter.

In addition to the submaster capabilities, each participant controller of the Flow Max system can display the measured flow. Flow is monitored at the Flow Max participant using the same key sequence as at the submaster.

Review Flow Max Physical Configuration

The Flow Max physical configuration can be reviewed after it has been entered into all Flow Max participants. The review capability is available at the submaster only.

Devices

From the Setup menu:

Reports & Diagnostics --> Diagnostics -->

to Communication screen --> FLOW MAX Comm --> to Devices

This screen shows all the devices attached to the Flow Max submaster and satellites, as well as flow measurements and whether or not the device (MV or pump) is On of Off.

Comm

The Comm screen displays communication information as well as the amount of time since the last successful communication.

Status

The Status screen displays the alert condition settings that will stop irrigation activity, such as a mainflow violation, unscheduled flow, etc.

FLOW MAX Comm WED 5:43:40 PM Comm Devices Status Stop Water Reasons Mainline Flow Violation No Unscheduled Flow No Flow Max Comm Error No Stop Water from Submaster No Auto-Learn No Monthly Water Limit Yes

This completes the Flow Max REVIEW ALL procedure.

Flow Max Warnings and Exception Conditions

All warnings referenced in this section are described fully in Chapter 8: Alerts. Please refer to that section for details. Most exception conditions result in warnings being generated at the submaster as well as each Flow Max participant.

Different information however will appear at different controller locations depending upon the circumstances.

Flow Max Lower Limit Violation

The submaster has determined that the measured flow from the flow meter(s) is less than the expected flow. All station run times associated with the (low) flow reading will be terminated. Programs automatically advance to their next scheduled station.

Flow Max Upper Limit Violation

The submaster has determined that the measured flow from the flow meters(s) is greater than the expected flow. All station run times associated with the (high) flow reading will be terminated. Programs automatically advance to their next scheduled station.

Flow Max Communications Failure

The hardwire data communications between the submaster and one or more satellites has been lost or interrupted. This may be indicative of a failure of the communications cable which runs to/from each satellite in a Flow Max configuration. All irrigation is terminated.

Flow Max Main Flow

The main line limit for the Flow Max system has been exceeded. All irrigation is terminated and all future scheduled irrigation will be inhibited.

Flow Max Unscheduled Flow

Flow was detected but no controllers within the system had any stations which were turned on. The normally open master valve will be energized and all future scheduled irrigation will be inhibited.

Appendix E: Hardwired Communication Troubleshooting

Rain Master® DX3 controllers are capable of communication between controllers to allow sharing of flow devices, Master Valves, pumps, as well as communication to Laguna central software. Controllers share communication via a hardwired connection. The hardwired communication is made via the EV-CAB-COMM cable due to its specific direct burial and communication properties. Each controller is wired in a daisy-chain configuration with the submaster being the starting point and the last controller being the ending point. Controller-to-controller connections are made via the "DX3 COMM BOARD" as seen below in figure D-2.

    L --> N["SATELLITE ADDRESS 1-2"]
    L --> O["To "IN" port"]

DX3 COMM BOARD: The DX3-COM-BOARD is seen below in figures 1 and 2. The board has LED indications for 5V and 12V power, and data traffic via the R (Receive), T (Transmit), and D (Direction) LED's. The board has designated inputs for communication coming "IN" from a upstream controller and "OUT" to a downstream controller. Each "IN" and "OUT" port has a polarity indication, "+" or "-" as well.

Normal Operating Behavior:

Indication LEDs

The indication LED's can be used to quickly diagnose normal operating behavior of a hardwired connected DX3 controller group. The 12V and 5V indication LED's should have constant solid illumination. The R, T, and D LED's will pulse illumination in a semi constant repeated pattern. Under normal operating conditions this sequence will repeat approx. every 1-2 seconds.

The T or R LED should pulse rapidly, if they stay solidly illuminated for longer than approx. 5 seconds, this is not typical behavior and the connections, field wiring and/or hardware should be inspected.

The D LED should pulse rapidly, like the T or R LED, but will hold it's illuminated state slightly longer. If the D LED stays solidly illuminated for longer than approx. 5 seconds, this is not typical behavior and the connections, field wiring and/or hardware should be inspected.

Note: The T, R, or D LEDs will be illuminated for the longest period of time when Laguna central software is communicating to a controller group.

Alerts

Under normal operating conditions a controller group should not experience HW communication related alerts. Generation of any of the alerts below in Table 1, is a sign of a problem, and connections, field wiring and/or hardware should be inspected.

Alarm Name Laguna	Code	Description Data
Satellite Offline 1112	Satellite lost	communication with submaster	- Time stamp of the violation
Satellite Online 1113	Satellite established	communication with submaster	- Time stamp of the violation
HW Communication Failure	1114 Submaster lost	communication with satellite	- Satellite(s) address of communication loss- Time stamp of the violation

Please note, if maintenance is being performed on a controller or a controller is powered down in a group, this will result in generation of communication related alerts.

Communication with Laguna Central Software

Communication with central software should be robust, especially for submasters communicating to Laguna via an Ethernet LAN connection. Wireless communication to Laguna from the submaster will be subject to errors and retries, especially compared to Ethernet LAN. Bottom line, no one controller in a hardwired group should experience an excess of communication failures compared to the other controllers in the group. If a specific controller in a controller group fails more, in comparison to the others, this is not normal operational behavior and connections, field wiring and/or hardware should be inspected.

Diagnostic View

The DX3 controller provides a useful diagnostic screen to triage and gauge controller-to-controller communication health. The diagnostic screen can be accessed by navigating to, Main Menu -> Reports & Diagnostics -> FLOWMAX and is shown below in figure 3.

FLOW MAX Comm WED 5:43:40 PM Comm | Devices | Status Good Packets 024033 Bad Packets 000017 Retry Packets 000000 Lost Sats 000000 My Address 1-0 Max Address 1-5 Min Flow Max 1-0 Last Comm 27 mins ago

Initiate a large communication (Statistics Upload or Program Upload/Download all Satellites) from Laguna Central Software to the suspect controller and monitor the diagnostic screen for 'Bad Packets' and 'Retry Packets'. If 'Bad Packets' and/or 'Retry Packets' are being generated as a result of the central communication, this is not normal operational behavior, and connections, field wiring and/or hardware should be inspected.

Controller Address Generation

Under normal operating conditions all downstream controllers wired to the submaster should be provided an address by the submaster. For Example, if the submaster uses address 001-00, the next controller downstream will be given address 001-01 and it will be displayed on the UI. Each successive downstream controller will be incremented by 1 (001-02, 001-03 ....). If any downstream controller reverts to its default address of 239-239, this is not normal operational behavior, and connections, field wiring and/or hardware should be inspected.

Inspecting Field Wiring:

Field wiring problem causes vary, but all typically result in a few types of failures, such as additional resistance, open circuit, short circuit and/or ground leakage.

Typical causes for these failures are a severed wire, poor/defective wire splice, defective wire insulator, water ingress or installation of the incorrect/poor quality underground communication cable. To test for these faults, try the following:

Test 1

Run a new communication cable above ground to the suspect controller. Exercise large communication to the controller from Laguna and monitor the controller communication diagnostic screen, communication board indication LEDs and generation of communication alerts.

Failure to observe normal operating behavior is indicative of a bad hardware module or inter hardware ribbon connectors (not a field wiring issue).

Test 2

Power down the suspect controller, upstream controller and downstream controller. Disconnect the communication cable from the suspect control. Connect the "IN" positive and negative wires together. Connect the "OUT" positive and negative wires together.

Disconnect the "OUT" communication cables from the upstream controller and probe resistance with multi-meter. Disconnect the "IN" communication cables from the downstream controller and probe resistance with multi-meter.

The resistance value probed for the "IN" and "OUT" lines should be proportional to the total field wire length run. EV-CAB-COMM has a resistance of 0.0333 Ohms/Meter. If the total wire length (up and back), is 250 meters, this should yield a resistance value of approx. 8 ohms (0.0333 ohm/meter * 250 meters = 8 ohms).

A higher than expected resistance value is indicative of poor splices or incorrect/poor quality cable.

An extremely high or open circuit value is indicative of a severed wire.

A lower than expected resistance value is indicative of a shorted wire.

Test 3

Power down the suspect controller, upstream controller and downstream controller. Disconnect the communication cable from the suspect controller, for both the "IN" and "OUT" connections.

Using a multi meter, make a resistance measurement between the disconnected "IN +" field wire and the enclosure chassis. Repeat the resistance measurement for the "IN - ", "OUT + , and "OUT - " with respect to the chassis.

The resistance values measured can range depending on the communication type, enclosure type and EV-CAB-COMM wire shield grounding. Valid Approx. measurement values for this test are:

OUT- ≈ 3.1K ohm, Mega ohms or Open Circuit

OUT_+ ≈ 3.2 ~K ohm

IN- ≈ 3.1K ohm, Mega ohms or Open Circuit

IN_+ ≈ 3.2Kohm

A lower than expected resistance value for any of the measurements in Test 3, are indicative of a ground leak or short in the communication wire. Additionally, resistance values greater than 4K ohm but less than 1Mega ohm are suspect of ground leaks.

Test 4

Power down the suspect controller, upstream controller and downstream controller. Disconnect the communication cable from the suspect controller, for both the "IN" and "OUT" connections.

Using a multi meter, make a resistance measurement between the disconnected "IN +" and "IN -" field wire. Repeat the resistance measurement for the "OUT +" and "OUT -" field wire.

The resistance value for the two measurements should be approx. 255 ohms.

A lower than expected resistance value are indicative of a ground leak short in the communication wire.

A higher than expected resistance value is indicative of poor splices or incorrect/poor quality cable.

An extremely high or open circuit value is indicative of a severed wire.

Test 5

Swap DX3-COM-BOARD, Timer Module (aka TM), and Interfacing cable between TM and COM board with known good hardware for both the suspect controller and upstream controller. Disconnect the communication cable "OUT" connections, if any, of the suspect controller.

Exercise large communication to the controller from Laguna and monitor the controller communication diagnostic screen, communication board indication LEDs, and generation of communication alerts.

Failure to observe normal operating behavior is indicative of a field wiring issue.

Glossary

Alert / Alarm

An irrigation related "event" reported by the controller which requires operator notification and/or action.

Central Control Mode

Central Control Mode indicates that two way communications have been established between the DX3 controller and the Central Control PC. This means that programming data can be downloaded and uploaded, and that the Central Control PC can control all functions remotely. Central Control Mode can be entered in two ways:

1. If a controller has been setup as a submaster and a valid address has been entered.
2. If the controller is physically connected as a satellite and has established two-way communications with its submaster.

Condemned Station

A station that shut down due to operational defects or exceeded limits. The condemned station will not operate again until the defects are corrected and warnings are cleared.

Continuous Cycle

A watering program that will run continuously within a user defined water window. After the first cycle, a specified soak time is enforced before the program starts again.

Controller

A microprocessor based solid state programmable apparatus that automatically

controls and manages irrigation valves, pumps, flow sensors and other peripheral devices. The term is used interchangeably with "satellite".

Controller Address

California Proposition 65 Warning Information What is this warning?

Sometimes you will see a product for sale that has a label with a warning along the lines of the following:

WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov.

The warnings is required by California labeling law Proposition 65 (or Prop 65 for short), which is meant to notify individuals in California of exposures to Prop 65-listed chemicals. Prop 65 does not ban the sale of any products containing these chemicals; it only requires warnings. Moreover, a Prop 65 warning does not mean a product is in violation of any product-safety standards or requirements. In fact, the California government has clarified that a Prop 65 warning “is not the same as a regulatory decision that a product is ‘safe’ or ‘unsafe’.”

See https://oag.ca.gov/prop65/faqs-view-all.

What is Prop 65?

Prop 65 is broad law that applies to any company operating in California, selling products in California, or manufacturing products that may be sold in or brought into California. It mandates that the Governor of California maintain and publish a list of chemicals that are known to cause cancer, birth defects and/or other reproductive harm. The list, which must be updated annually, includes a wide variety of chemicals that can be found in many everyday items. The purpose of Prop 65 is to ensure that people are informed about exposure to these chemicals.

Prop 65 also requires warnings to be placed on any product, product packaging, or literature accompanying a product that contains or may contain any of the hundreds of chemicals that the State of California considers harmful. Many of the chemicals listed under Prop 65 have been routinely used in everyday products for years without documented harm.

A Prop 65 warning generally means one of two things: (1) a business has evaluated the exposure and has concluded that it exceeds the “no significant risk level”; or (2) a business has chosen to provide a warning simply based on its knowledge or understanding about the presence of a listed chemical without attempting to evaluate the exposure.

Does this law apply everywhere?

Prop 65 warnings are only required under California law. Prop 65 warnings are seen throughout California in a wide range of settings -- in restaurants, grocery stores, hotels, schools, hospitals, and on a wide variety of products. In addition, some Internet and mail order retailers have chosen to provide Prop 65 warnings on their websites or in catalogs for all their products and for all consumers. Prop 65 standards are among the most stringent standards in place anywhere and are often far more stringent than federal standards.

How do the California warnings compare to federal limits?

It should be noted that California product label warning requirements are not usually the same as federal safety requirements. This causes a variance between warnings on products sold in California and what is required elsewhere in the U.S.A and other parts of the world. This can explain why sometimes you may see a Prop 65 warning on a product sold in California but no warning on the same product sold elsewhere. The products are not different but Prop 65 warnings are required for sales in California.

Additionally, there are various substances that require a Prop 65 warning at levels that are far more stringent than federal action limits. One example is lead. The Prop 65 standard for warnings for lead is 0.5 micrograms per day, which is far more stringent than federal and international standards for lead.

Why don't all similar products carry the warning?

There could be a variety of reasons. If a company has been involved in a Prop 65 lawsuit, and if that company reaches a settlement, that settlement may require Prop 65 warnings for products.

Other companies that are not involved in the settlement, although they may nonetheless sell similar products, may not provide a warning on their product. Because of inconsistent Prop 65 enforcement, this sometimes explains why you will see certain products in the market with warnings, and virtually identical products without warnings. Other companies may elect not to provide warnings because, in their assessment, they conclude that they are not required to do so under Prop 65 standards. A lack of warnings for a product does not necessarily mean that the product is free of the same substances at similar levels.

Why does Rain Master include this warning?

Rain Master believes the best practice is to provide consumers with as much information as possible so they can make informed decisions about the products they purchase and use.

Rain Master has chosen to provide warnings in certain cases based on its knowledge about the presence of one or more listed chemicals without attempting to evaluate the level of exposure, as not all of the listed chemicals provide exposure limit requirements. With[Brand Name]'s products, the exposure may be negligible or well within the "no significant risk" range.

However, out of an abundance of caution, Rain Master has elected to provide the Prop 65 warnings. Moreover, if Rain Master does not provide these warnings, it can be sued by the State of California or by private parties who seek to enforce Prop 65 and subject to substantial penalties.
