Frequently Asked Questions - WS-PRO2 RAIN BIRD

How do I orient the wind sensor to true north?

Determine magnetic declination for your location using an online calculator (e.g., NOAA). Align the wind sensor arrow with true south (northern hemisphere) or adjust according to declination. See Appendix B in the manual.

What is the recommended maintenance schedule for the rain gauge?

Inspect and clean the rain gauge screen and funnel weekly. Remove debris and ensure the tipping mechanism is level. Use the bubble level inside the gauge.

Can I use a cellular modem with the WS-PRO2?

Yes, a cellular modem accessory kit is available. It supports modems like CELL210 and RV50. A separate antenna and cellular service plan are required. Refer to the manual for installation and power considerations.

How often should I replace the desiccant packs in the enclosure?

Replace desiccant when the internal humidity sensor exceeds 50% RH. At a minimum, replace annually, but more frequent changes may be needed in humid environments. Use two packs per enclosure.

What should I do if the data logger shows no response?

Check battery voltage (9.6-16 VDC on 12V and G terminals). Ensure the PS150 power switch is ON. Verify ribbon cable connections and cycle power. If using a communication peripheral, check connections and configuration at both ends.

How do I clean the pyranometer (solar radiation sensor)?

Check monthly for level and contamination. Gently clean with a blast of dry air, a soft camel hair brush, or clean water if needed. Do not scratch the sensor surface. Avoid using solvents.

What is the proper procedure for grounding the weather station?

Drive a ground rod near the concrete foundation. Connect a 4 AWG ground wire from the rod to the pole ground lug. Also connect the enclosure ground (10 AWG) to the lightning rod clamp. See Appendix A for detailed grounding designs.

Can I use the station with a Wi-Fi connection?

Yes, an NL241 Wi-Fi accessory kit is available. It installs inside the enclosure and uses an external omnidirectional antenna. AC power or a larger battery (PS24) is recommended for reliable operation.

How do I replace the RH chip in the temperature/humidity sensor?

Unscrew the protective cap, hold the plastic sides of the chip, and unplug it. Rinse the new chip with distilled water (if needed), then plug it in and screw the cap back on. Handle the chip carefully to avoid scratching.

What is the expected lifespan of the internal lithium battery in the data logger?

Approximately 10 years at room temperature when not powered externally. When the station is powered most of the time, it lasts much longer. Replace when voltage drops to about 2.7 V. Factory replacement is recommended.

1. Introduction

The Rain Bird WS-PRO2 Weather Station, when used in conjunction with the Rain Bird Cirrus, Nimbus II, or Stratus II Central Control system, provides the irrigation professional with a powerful tool to aid in the growing of lush, healthy, green turf grass, while conserving important resources, such as water, power, etc.

Rain Bird SmartWeather software interrogates the WS-PRO2 weather station to retrieve information that has been gathered on a daily basis of the climatic conditions that affect the irrigation application for the area.

The SmartWeather software subjects the climatic information that it gathers to a version of the modified Penman Equation. The Penman Equation has been proven through over 35 years of university research to be one of the most reliable predictors of turf grass water use requirements.

The weather station monitors the following climatic conditions:

• Rainfall
  • Wind speed and direction
• Air temperature
• Relative humidity
• Solar radiation

The standard WS-PRO2 configuration includes sensors to monitor these conditions, a data logger to capture this data, a modem to communicate the information to the SmartWeather software located on the central control computer, and a power supply.

2. Precautions

• READ AND UNDERSTAND the Safety section at the back of this manual.
• DANGER: If any part of the weather station comes in contact with power lines, you could be killed. Contact local utilities for the location of buried utility lines before digging or driving ground rods.
• Avoid dangerous electrical accidents when using the AC power option by locating the transformer remotely and burying a low voltage line to the station. The low voltage will carry up to 152 m (500 ft) on an 18 AWG power cable.
• Carefully handle the WS-PRO2 components during transport, installation, and cleaning.
• Leave the 034B wind vane in the protective cardboard sleeve until it's ready to be installed.
• Ensure to remove the yellow cap from the RH and temperature sensor, the red or green cap from the pyranometer, and the rubber band from the tipping bucket mechanism. Save the caps for shipping or storing the sensors.
• When connecting cables to the enclosure panel, ensure that each plug is completely seated on the connector and the locking ring is turned a quarter revolution clockwise. Failure to seat the plug completely could cause corrosion and water damage to both the enclosure and the cable.
• WARNING: Misuse of the lithium battery in the data logger or installing this lithium battery improperly can cause severe injury. It is a fire, explosion, and severe burn hazard! Do not recharge, disassemble, heat above 100 °C (212 °F), solder directly to the cell, incinerate, nor expose contents to water. Lithium batteries need to be disposed of properly. Refer to Data logger module (p. 69) for more information.

5. Siting and exposure

DANGER:

If any part of the weather station comes in contact with power lines, you could be killed. Contact local utilities for the location of buried utility lines before digging or driving ground rods.

Selecting an appropriate site for the weather station is critical to obtain accurate meteorological data. In general, the site should be representative of the general area of interest, and away from the influence of obstructions such as buildings and trees.

The weather station should not be located where sprinkler irrigation water will strike sensors or instrument enclosure.

Some general guidelines for site selection are listed below, which were condensed from EPA (1988), WMO (1983), and AASC (1985) publications. See References (p. 79).

5.1 Wind speed and direction

Wind sensors should be located over open, level terrain, and at a distance of at least ten times (EPA) the height of any nearby building, tree, or other obstruction (FIGURE 5-1 (p. 10)).

FIGURE 5-1. Effect of structure on wind flow

5.2 Temperature and relative humidity

Sensors should be located over an open, level area at least 9 m (29.5 ft) (EPA) in diameter. The surface should be covered by short grass, or where grass does not grow, the natural earth surface. Sensors should be located at a distance of at least four times the height of any nearby obstruction and at least 30 m (98.43 ft) (EPA) from large paved areas. Sensors should be protected from thermal radiation and adequately ventilated.

Situations to avoid include:

• large industrial heat sources
- rooftops
- steep slopes
- sheltered hollows
- high vegetation
- shaded areas
- swamps
- areas where snow drifts occur
- low places holding standing water after rains

5.3 Solar radiation

Pyranometers should be located to avoid shadows on the sensor at any time. Mounting it on the southernmost (northern hemisphere) portion of the weather station will minimize the chance of shading from other weather station structures. Reflective surfaces and sources of artificial radiation should be avoided.

(3) 16 mm (5/8 in) anchor L-bolts
(9) 16 mm (5/8 in) nuts
(1) anchor template

The pole attaches to a user-supplied concrete foundation constructed as shown in FIGURE 6-1 (p.13).

FIGURE 6-1. WS-PRO2 pole base installation

1. Construct the concrete form with 5 cm x 10 cm (2 in x 4 in) lumber and 16p nails.
2. Assemble the template and anchor bolts. For each bolt, place two nuts below and one nut above the template.
3. Clear an area large enough to set the form at the desired elevation.
4. Dig a hole 0.6 m x 0.6 m x 0.6 m (2 ft x 2 ft x 2 ft). Lighter soils may require a deeper hole.
5. About 50 cm (20 in) below the top of the hole, gouge a small cavity in one wall of the hole. The cavity should be about 10 cm (4 in) deep and just large enough in diameter to insert one end of the conduit. Make certain the cavity points in the direction from which power and communications cables will come. For example, the cavity will point towards a valve box if one is being used.
6. Center the form over the hole. Adjacent to the form, drive four stakes into the soil. Secure the leveled form to the stakes with the 8p nails.
7. Cap the ends of the conduit with duct tape.
8. Position the conduit then wire into place by securing the wire to nails in the form.
9. Fill the hole and form with approximately 0.5 m (0.5 yards) of concrete. Screed the concrete level with the top of the form.

10. Center the template assembly over the conduit and press into the concrete.

11. Put 2-by-4 spacers between the template and the top of the form. The bottom of the bolt threads should be about 1 cm (0.5 in) above the concrete (FIGURE 6-2 (p. 14)). The template must be level in two dimensions.

FIGURE 6-2. Cut-away view shows anchor bolt and conduit placement in cement pad

6. Cut and save a 23 cm (9 in) piece of 10 AWG ground wire, which will be used to attach the enclosure ground to the lightning rod assembly.

7. Thread the communications cable, power cable with connector ends of cable out the top of pole, and grounding wire through the pole and conduit. Electrical fish tape will help. Leave approximately 1 m (2 ft) of the supplied power and communications cable hanging out of the top of the pole. Secure all wiring so it doesn't slip back down through the pole.

NOTE:

Solar panel and radio frequency (RF) options will not have power or communications cables.

1. Place the white pole cap over the pole end.

2. Raise the pole on a still day.

3. Place a washer on top of the two nuts on each foundation bolt.

4. Taking care not to damage cables between the pole and conduit, raise the pole and lower it onto the conduit and mounting bolts.

5. Install a washer and nut on each bolt and hand tighten. Check plumb of the pole by placing a level on the north and east sides of the lower pole section.

6. Adjust the topmost of the two lower nuts (leveling nut) on each bolt as necessary.

7. When plumb is established, lock the leveling nut in place by tightening the lowest nut against it.

8. Tighten the three top nuts with the wrench.

6.6.6 107 or 108 soil temperature sensor (optional)

The 107 and 108 temperature sensors have a -C Cable Termination option that allows them to connect to the WS-PRO2. With this option, the cable terminates in a connector that attaches to the WS-PRO2. This is equivalent to the -LC version available for some sensors.

NOTE:

Rain Bird recommends routing the cable of the optional soil sensors in conduit, especially if the soil is rocky or rodents are present. The cables for these sensors do NOT have an armored outer jacket. The jacket is waterproof but NOT cut proof.

1. Bury the conduit from the weather station to the soil temperature site.
2. Route the sensor cable through the conduit.
3. Bury the end of the sensor so it is in contact with the soil surface to be measured. See sensor manual for complete instructions.
4. Plug this sensor into one of three possible connectors on the WS-PRO2 enclosure. Check the programming software for correct station connection. Ensure that the plug is completely seated on the connector and the locking ring is turned a quarter revolution clockwise.

6.6.7 Sensor connections

Each sensor cable plug attaches to a unique bulkhead connector (FIGURE 6-6 (p. 20) and FIGURE 6-21 (p. 34)). The labeling of the sensor cables match the labeling on the back of the enclosure. For more information, refer to Sensor schematics (p. 73).

CAUTION:

Each plug must be completely seated on to the connector and the locking ring turned a quarter revolution clockwise. Failure to seat the plug completely could cause corrosion and water damage to both the enclosure and the cable.

NOTE:

Notice how the sensor caps are slid between the connector and the one above in FIGURE 6-21 (p. 34). This will keep the caps out of the way of the connector cover.

FIGURE 6-21. Connecting sensor cabling to enclosure

6.6.8 Sensor verification and clock set

1. Contact Rain Bird if needed to assist with SmartWeather software setting changes necessary to activate soil temperature.

a. The station can be accessed directly using a CR1000KD keypad display at the weather station. Plug the keypad into the extra plug coming off the 9-pin CS I/O connector.

b. A laptop can be used to connect directly to the RS-232 port at the station using a standard 9-pin serial cable. Do NOT use a null modem cable.

6.7 Communications peripherals

Communications kits ordered with the enclosure are pre-mounted and pre-wired; no further connections inside the enclosure are necessary. Follow the external installation procedures in later sections to make the external connections.

If you received a telecommunications kit separate from the enclosure, follow the "Internal Installation" procedures outlined in later sections. Schematics for the phone and short haul modems are in Communications modems schematics (p. 78).

Default settings for the data logger in the WS-PRO2 station:

• PakBus address 1
  • RS-232 Port: Autobaud (300 to 115,200 bps)
  • ME: Autobaud
  • SDC7 or SDC8: 115,200 bps

6.7.1 Direct connect to WS-PRO2 station

The WS-PRO2 station does not require an interface device for direct RS-232 communications. The inside of the enclosure has a RS-232 and CS I/O port available for communications (see FIGURE 6-22 (p. 36)). Most standard communications options use the CS I/O port leaving the RS-232 port free for direct communications with a laptop or desktop computer using a standard RS-232 serial cable. The data logger used in the WS-PRO2 station can communicate with more than one device at a time allowing troubleshooting to be done in the field with a laptop computer while remote communications devices are accessing the station.

NOTE:

Use Device Configuration Utility and connect directly to the station to change the data logger configuration. Device Configuration Utility can be obtained, at no charge, from

www.campbellsci.com/downloads

3. Route the user-supplied cable from the remote splice to the surge protector. Connect it and the 1.5 m (5 ft) patch cable to the surge protector.

6.7.4 Radio

Radios enable wireless communications between a data logger and computer. Maximum range is 0.8 to 21 km (0.5 to 13 miles). This is determined by radio model, antennas used, line of site, and interference. Radio communications using the SmartWeather alarm systems require an SC932A RS-232 DCE Interface and a field power cable. The SC932A is connected between the radio RS-232 port and the WS-PRO2 CS I/O port. For the field power cable, the barrel plug connects to the radio and the two-conductor pigtail connects to the 12V and G terminals of the WS-PRO2. This section provides instructions for RF407, RF412, RF422, RF451 and most radios offered by Campbell Scientific.

NOTE:

AC power is recommended when using radios with the station. A 10-watt solar panel can be used but days without sunlight and winter months with little sunlight should be considered. The WS-PRO2 station comes with a 7 amp-hour battery that is NOT designed to handle deep discharge. Discharging the battery below 11 VDC may require battery replacement. Below are some examples of power calculations. Battery current consumption is based on discharging the 7 amp-hour battery to 80% capacity (5.6 amp-hours). Discharging the battery past this value could result in damaging the battery.

6.7.4.1 Example radio configuration and power usage

Configuration of base radio at the computer:

• Multi-Point Master
  • RS-232 @ 9600 bps
  • Network ID: 1234
• Frequency Key: 5
  • 1 Watt Output (Transmit Power: 10)

Weather station radio:

• Multi-Point Slave
  • Communication with Data logger via CS I/O SDC7
  • Network ID: 1234
• Frequency Key: 5
  • 1 Watt Output (Transmit Power: 10)
• Low Power Mode: 2

See your spread spectrum radio manual for changing radio settings.

Power usage example:

Polling the station once an hour and staying on line with the station for one minute consumes approximately 0.388 amps over a 24-hour period. If the station were to lose power, it could run for around 14 days (346 hours) before damaging the battery. A station with a 10-watt panel would need at least one hour of sunlight every day to keep the battery charged.

6.7.4.2 Internal installation of the radio

NOTE:

If the WS-PRO2 was ordered with a radio kit, skip this section and go directly to External installation of the radio (p. 44).

The following components are provided in the radio kit for installation inside the WS-PRO2 enclosure:

FIGURE 6-32. Mount antenna saddle bracket

NOTE:

Only rotate enclosure if needed to allow aiming of the Yagi antenna to the base antenna. Keep solar radiation sensor towards the south as much as possible. Rotate wind sensor to realign as needed.

1. Use the following procedure to install the Yagi antenna for the radio. Installation of the omnidirectional antenna is similar (FIGURE 6-35 (p. 49)).

NOTE:

Mounting hardware that comes in the box with the Yagi antenna will not be used.

a. Slide the back of the Yagi antenna into the saddle bracket.
b. If the Yagi antenna at the station is communicating with an omnidirectional antenna at the base, align the tines on the Yagi antenna so they are vertical (FIGURE 6-33 (p. 48)). If two Yagi antennas are used at both ends of communications, align the tines the same. If interference is a concern, align the tines on the two Yagi antennas horizontally instead of vertically. This will put the signal out of phase with other antennas that are aligned vertically.

c. Tighten the nuts on saddle bracket to hold the antenna firmly in place.

CAUTION:

Do NOT over tighten the nuts on the saddle bracket or damage to the antenna may occur.

(1) adjustable angle antenna mounting bracket
(1) 8-450 x 53 mm (5/16-18 x 2 1/4 in) stainless steel U-bolt
(1) CM230 saddle bracket
(4) silicon bronze 8-450 mm (5/16-18 in) nuts
(4) 8 mm (5/16 in) stainless steel washers
(4) 8 mm (5/16 in) stainless steel lock washers
(4) black UV-resistant wire ties

1. Fasten the mounting hardware onto the WS-PRO2 pole by following steps 1 through 8 in External installation of the radio (p. 44).
2. Slide the back of the antenna into the saddle bracket and tighten its nuts to hold the antenna firmly in place.

CAUTION:

Do NOT over tighten the nuts on the saddle bracket or damage to the antenna may occur.

1. If using the Yagi antenna, aim the antenna at the cellular pole. You may have to flip the adjustable angle bracket over to get the antenna and saddle bracket to point correctly in the vertical direction.
2. Adjust the antenna cable at the BNC connector so the cable cover fits over all the sensor cables and the antenna cable. You may have to gently bend the antenna cable to put a 90° bend by the BNC connector end of the cable. Take the cover off when you're done.
3. Use one of the black wire ties to strap the antenna cable to the bundle of sensor cables.
4. Tighten up the wire ties holding the antenna cable to the wire tie mount at the top of the enclosure.
5. Take one black wire tie and strap the antenna cable to the antenna. Leave a little slack on the cable between the wire tie and the antenna connector so as not to stress the connector/cable connection.
6. Wire tie the antenna cable to the pole. Clean up the wire ties and put the cable cover back on.

6.7.6 NL241 Wi-Fi accessory kit

The wireless network link kit includes hardware for installing a Wi-Fi network link into an WS-PRO2 weather station. The Wi-Fi modem accessory kit and antenna are ordered separately.

6.7.6.1 Antenna

Rain Bird recommends the 2.4 GHz 5.8 dBd omnidirectional antenna with the NL241 Wi-Fi modem in an WS-PRO2 station. This antenna provides a 5.8 dBd gain.

The Wi-Fi kit provides the hardware needed to mount the antenna to the WS-PRO2 pole.

6.7.6.2 Power considerations

Rain Bird recommends using either AC power or a 10-watt solar panel and the PS24 power supply. Refer to PS24 24 Ah power supply with 10 x 12 inch enclosure (p. 91) for mounting options and information on the PS24.

6.7.6.3 Internal installation of Wi-Fi modem

6.10 Battery installation

FIGURE 6-44. PS150 with lid open

1. Move the PS150 power switch to the OFF position (FIGURE 6-44 (p. 61)).
2. Remove the cover from the PS150 by sliding the latch up at one end of the cover and sliding the cover down and out (FIGURE 6-44 (p. 61)).
3. Install the battery according to the diagram (FIGURE 6-44 (p. 61)).
4. Plug the battery wire into the connector.
5. Put the cover back on the PS150 and latch it in place.

NOTE:

Do not switch the power supply ON until AC or solar power has been connected to the back of the enclosure.

The green charge light on the PS150 will flash when charging voltage is present. The charge light is not affected by the switch. Switching on the power supply without a charging voltage will run the battery down.

FIGURE 6-45 (p. 62) shows factory wiring between the PS150 and the enclosure.

FIGURE 6-45. PS150 to WS-PRO2 enclosure wiring

6.11 Restraining cables

1. Loosely wire tie power, communications, and grounding cable to the wire tie harness at the top of the back of the station (FIGURE 6-46 (p. 62)). Do NOT clip back the wire tie at this time.

FIGURE 6-46. Cabling strapped to wire tie harness

1. Replace the connector cover. The tab at the top of the connector cover slides into the opening on the back of the crossarm. Ensure that all cables and connector caps are under the cover before tightening the Phillips screw at the bottom of the cover. Make sure that all cables coming out of the top right of the connector cover are not being pinched.

FIGURE 6-47. Connector cover in place

1. Tighten the wire ties holding the cables to the wire tie harness and clip off excess ties (FIGURE 6-47 (p. 63)).

6.12 Sealing and desiccating the enclosure

The WS-PRO2 enclosure is supplied with two desiccant packs. The desiccant maintains a low humidity in the enclosure to minimize the chance of condensation on the instrumentation. Desiccant should be changed when the internal enclosure humidity sensor measures 50% or higher. Install the desiccant as shown in FIGURE 6-48 (p. 64). Keep unused desiccant tightly sealed in an airtight container.

NOTE:

Place the desiccant into the enclosure after all other weather station installation steps have been completed.

1. Take the desiccant packs out of the plastic bag.
2. Strap the packs into the desiccant holder inside the lid of the enclosure using the two Velcro straps.
3. Close the enclosure hasp securely. A padlock may be used on the latch for extra security.

FIGURE 6-48. Desiccant installation

6.13 WS-PRO2 software

A variety of different software packages are available to work with the WS-PRO2 station. Contact Rain Bird as needed for support.

7. Maintenance and troubleshooting

NOTE:

All factory repairs and recalibrations require a returned material authorization (RMA) and completion of the "Declaration of Hazardous Material and Decontamination" form. Refer to the Assistance page at the end of this manual for more information.

7.1 Maintenance

Proper maintenance of the WS-PRO2 components is essential to obtain accurate data. Equipment must be in good operating condition, which requires a program of regular inspection and maintenance. Routine and simple maintenance can be accomplished by the person in charge of the weather station. More difficult maintenance such as sensor calibration, sensor performance testing, and sensor component replacement, generally requires a skilled technician, or that the instrument be sent to Campbell Scientific or the manufacturer. Refer to the Assistance page at the end of this document for the procedure of returning components to Campbell Scientific.

A station log should be maintained for each weather station that includes serial numbers, dates that the site was visited, and maintenance that was performed.

7.1.1 Pole maintenance

Periodically check the pole for structural damage, proper alignment, and for level/plumb.

7.1.2 Power supply maintenance

Rechargeable power supplies should be connected to an AC transformer or unregulated solar panel at all times. The PS150 green charge light will flash when voltage to the charging circuitry is present. The charge indicating light runs independent of the power switch. Be aware of battery voltage that consistently decreases over time, which indicates a failure in the charging circuitry. Short Cut and VisualWeather automatically program the weather station to measure battery voltage.

Occasionally clean the glass on the solar panel to improve its efficiency. Use warm mildly soapy water and a clean cloth. Rinse with clean water.

7.1.3 Desiccant

Humidity is monitored inside the WS-PRO2 enclosure using the Elan HM2000 RH sensor that is incorporated in the enclosure. Change the desiccant packs when the enclosure RH exceeds 50%. The enclosure RH sensor should be changed approximately every five years.

Desiccant packs may be ordered in quantity of 20 individually sealed packs at a time or by the individual pack.

7.1.4 Sensor maintenance

Perform sensor maintenance at regular intervals, depending on the desired accuracy and the conditions of use. A suggested maintenance schedule is outlined below. WS-PRO2 maintenance log (p. 103) provides an example of a maintenance log file for one year of station use.

1 week

- Check the rain gauge screen and funnel for debris and level.

1 month

- Check the solar radiation sensor (pyranometer) for level and contamination. Gently clean with blast of dry air, soft camel hair brush, or clean water if needed.

CAUTION:

Handle the pyranometer carefully when cleaning. Be careful not to scratch the surface of the sensor.

• Do a visual/audio inspection of the 034B-ET anemometer at low wind speeds. Worn bearings can cause the wind cups to spin in an uneven manner and/or make a grinding sound.
• Check the WindSonic1-ET for contamination. If needed, gently clean the WindSonic1 with a cloth and mild detergent.

CAUTION:

When cleaning the WindSonic1, do not use solvents and avoid scratching the sensor.

3 months

- Clean the radiation shield by removing the two knurled thumb screws holding it to the crossarm. Gently pull the sensor out of the shield. Clean the radiation shield using warm mildly soapy water. Rinse with clean water and allow the shield to dry before putting it back on the crossarm.

- If necessary, clean the white filter element on the end of the temp/RH sensor. To clean the filter, unscrew it from the end of the sensor and put it in a cup of CLEAN DISTILLED WATER. Use no soap. Agitate the filter in the cup of water. Remove the filter and allow to air dry before putting it back on the end of the sensor.

6 months

- Replace the anemometer bearings and reed switch on the 034B-ET if operating under harsh conditions, such as constant high winds, blowing dust, and/or salt spray contamination. Return the sensor to Campbell Scientific for bearing and reed switch replacement (see Assistance page).

1 year

- Replace the wind speed (anemometer) bearings on the 034B-ET. Return the sensor to Campbell Scientific for bearing replacement (see Assistance page).

- Replace reed switch the 034B-ET if needed. Return the sensor to Campbell Scientific for bearing replacement (see Assistance page).

- Check calibration of the HMP60-ETS Temp/RH sensor, which tends to drift up over time giving readings higher than 100%. Replace RH chip if necessary (refer to FIGURE 7-1 (p. 68) and Procedure for removing RH chip (p. 69)).

NOTE:

WS-PRO2 stations began shipping January 2014 with an updated radiation shield with knurled thumb screws, using the HMP60 ETS Temp/RH sensor. All information in this document is also pertinent for the HMP50-ET, HMP60-ET, and HMP60 ETR sensors.

- Replace desiccant in enclosure housing as needed.

FIGURE 7-1. Exploded view of the temperature and RH sensor (adapter not shown)

2 years

• Replace vane potentiometer of the 034B-ET if needed (refer to www.campbellsci.com/order/034b-et for part number and price). To send the sensor to Campbell Scientific for potentiometer replacement, refer to the Assistance page.
• Replace enclosure gasket if necessary. Refer to the Assistance page if sending the enclosure to Campbell Scientific for gasket replacement. Refer to www.campbellsci.com/p10505 to replace gasket in the field.

3 years

- Send the solar radiation sensor (pyranometer) to Campbell Scientific for calibration (refer to the Assistance page). Sensor cannot be calibrated in the field. (Some users recommend calibrating this sensor on a yearly basis.)

4 to 5 years

• Check sensor cables (as well as all other cables) for cracking, deterioration, proper routing, and strain relief. Replace as required.
• Check enclosure relative humidity sensor. To check this sensor, take the lid off the enclosure during routine desiccant replacement and leave it off for 5 to 10 minutes before

putting in new desiccant. While the lid is off the enclosure, compare the internal enclosure humidity to the air humidity. Replace if >10% off.

7.1.4.1 Procedure for removing RH chip

1. Unscrew the protective cap (see FIGURE 7-1 (p. 68)).
2. Hold the plastic sides of the RH chip and unplug it.

CAUTION:

To prevent scratching, avoid touching the silver chip, and handle the RH chip with care.

1. Rinse off the RH chip with distilled water or dispose of the old RH chip.
2. Hold the sides of the rinsed or new chip and plug it in.
3. Screw on the protective cap.

7.1.5 Data logger module

The data logger module contains a lithium battery that operates the clock and SRAM when the module is not powered. The data logger does not draw power from the lithium battery while it is powered by a 12 VDC supply. In an WS-PRO2 stored at room temperature, the lithium battery should last approximately 10 years (less at temperature extremes). Where the WS-PRO2 is powered most or all of the time, the lithium cell should last much longer.

While powered from an external source, the module measures the voltage of the lithium battery daily. This voltage is displayed in the status table. A new battery will have approximately 3.6 volts. The data logger Status Table has a "Lithium Battery" field. This field shows lithium battery voltage.

Send the WS-PRO2 enclosure to Campbell Scientific to have Campbell Scientific replace the battery when voltage is approximately 2.7 V (see Assistance page). If the lithium cell is removed or allowed to discharge below the safe level, the WS-PRO2 will still operate correctly while powered. Without the lithium battery, the clock will reset and data will be lost when power is removed.

CAUTION:

Campbell Scientific recommends factory replacement of the lithium battery. Misuse of the lithium battery in the data logger or installing this lithium battery improperly can cause severe injury. It is a fire, explosion, and severe burn hazard! Do not recharge, disassemble, heat above 100 °C (212 °F), solder directly to the cell, incinerate, nor expose contents to water. Lithium batteries need to be disposed of properly.

Table 7-1 (p. 70) lists the specifications of the battery.

Table 7-1: Data logger lithium battery specifications

7.2.1 No response using the CR1000KD keypad

Check keypad response after each of the following steps.

1. Make sure the battery has been installed and the PS150 power switch is set to ON (Battery installation (p. 61)).
2. Use a voltmeter to measure the voltage on the 12V and G terminals (FIGURE 6-45 (p. 62)); the voltage must be from 9.6 to 16 VDC.
3. Use a voltmeter to measure the voltage on the 5V and G terminals (FIGURE 6-45 (p. 62)); the voltage must be from 4.9 to 5.1 VDC.
4. Disconnect the Temp/RH sensor from the back of the enclosure.
5. Disconnect the 9-pin ribbon cable from any communications option used with the station so that only the keypad is attached to the 9-pin plug in the lower right corner of the enclosure.
6. Cycle the power to the data logger by switching the PS150 power supply to OFF then to ON, or by disconnecting and reconnecting the battery plug. The keypad should power up and the Campbell Scientific logo and text should appear on the display.
7. Call Rain Bird GSP if still no response.

7.2.2 No response from data logger when using a communications peripheral

At the data logger:

1. Make sure the battery has been installed and the power switch set to ON (Battery installation (p. 61)).
2. Use a voltmeter to measure the voltage on the 12V and G terminals (FIGURE 6-45 (p. 62)); the voltage must be between 9.6 and 16 VDC.
3. Use a voltmeter to measure the voltage on the 5V and G terminals (FIGURE 6-45 (p. 62)); the voltage must be between 4.9 and 5.1 VDC.
4. Make sure the data logger is connected to the communications peripheral, and the communications peripheral is properly installed and configured (Communications peripherals (p. 35)).

At the computer:

1. Make sure calling software is properly configured (SmartWeather, Maxicom, IQ, etc.).
2. Check the cable(s) between the serial port and the modem. If cables have not been purchased through Campbell Scientific, check for the following configuration using an ohm meter:

9-pin to 25-pin serial cable
Computer end	Modem end
2	3
3	2
4	20
5	7

1. Make sure the communications device at the computer is properly configured and cabled (Communications peripherals (p. 35)).

2. Call Rain Bird GSP if still no response.

7.2.3 NAN, ±INF, or unreasonable results displayed in a variable or stored in a data table

1. Make sure the battery voltage is between 9.6 and 16 VDC.
2. Verify sensors are plugged into the correct sensor connector and the locking ring is securely in place (see FIGURE 6-21 (p. 34)).
3. Check connectors for any corrosion on pins.
4. Inspect the sensor for damage and/or contamination. If damaged, contact Rain Bird GSP for repair or purchase of a replacement sensor.

7.2.4 WindSonic1-ET diagnostic codes

The WindSonic outputs a diagnostic code (Table 7-2 (p. 72)) with each wind direction and speed measurement. A data logger program can be written that filters out all data when the diagnostic is not 0. The programs can also report the number of good samples that were used in computing the on-line statistics. If the total number of good samples is less than 98% of the expected samples, the WindSonic may be in need of repair.

Table 7-2: WindSonic Diagnostic Codes

Appendix A. Grounding recommendations

A.1 Grounding system installation

To prevent lightning damage to your equipment, Rain Bird recommends installing a grounding system for the equipment (including controllers, weather stations, and central control systems). The grounding system discharges lightning-induced electrical current into the earth rather than allow the surge to pass through power wires or field wires to your equipment's electronic components.

A.1.1 Ground resistance

Ground resistance occurs when grounding system components, or the soil itself, oppose the flow of electricity into the earth. Ground resistance is measured in units called "ohms" (Ω). The higher the ground resistance (higher ohm readings), the less chance the surge will be shunted to ground rather than to the equipment's electronic components.

FIGURE A-1 (p. 81) shows points where grounding systems can develop resistance. To decrease ground resistance, Rain Bird recommends irrigating the soil around the grounding system. Each grounding system should have a dedicated irrigation zone with sprinkler heads and its own watering program to maintain soil moisture around the grounding system.

A properly installed grounding system should maintain a maximum ground resistance of 10 ohms or less. If you are unable to reach a resistance of 10 ohms or less, you can decrease resistance by surrounding the grounding rods or plates with ground enhancement material, such as POWER SET from Paige Electric Corporation (pn 1820058), or GEM from ERICO (pn GEM-25A).

If ground resistance still measures higher than 10 ohms, you can extend the ground rod length as described in "Ground Rod Stacking," or use additional grounding rods, as shown in grounding system design "Y" (Alternate).

A.1.2 Installation requirement

The following requirements apply to all grounding system designs (design Y and the "Grounding Plate" design). All grounding rods or plates must be connected together below grade with #6 AWG or larger solid bare copper wire.

Install the connecting wire in as straight a line as possible. If you must make a turn or bend in the wire, make the turn in a sweeping curve with a minimum radius of eight inches and a minimum included angle of 90^ .

To minimize resistance, the copper wire must be pre-welded to the grounding rods/plates, or welded to the rods/plates using an exothermic welding process at the site.

Make sure all welds are secure before burying the grounding rods. Rods and plates with welded joints do not need periodic visual inspection and can be fully buried (no valve box required). Measure the ground resistance around the grounding system after installation, and once every year after that.

NOTE:

The ground wire from the equipment to the grounding system should be as short as possible and have no bends, kinks, or coils in the wire.

Inspect the grounding system's clamped connections to the equipment (not the welded grounding system connections) once a year to make sure they are secure and corrosion-free.

FIGURE A-1. Grounding systems can develop resistance at many points

A.1.3 Ground rod stacking

Threaded couplers (shown in FIGURE A-2 (p. 82)) are ground rod splices. If a single grounding rod fails to produce 10-ohm ground resistance (maximum), threaded couplers can be used to "stack" grounding rods.

NOTE:

Use threaded couplers made of the same material as your grounding rods.

Stacking ground rods increases the total effective rod length, decreasing ground resistance. Joining the rods together with threaded couplers forms a secure connection so the grounding rods can be assembled quickly and easily.

FIGURE A-2. Stacking grounding rods with threaded couplers can help decrease ground resistance

A.2 Grounding system designs

A.2.1 Design "Y"

Design "Y" (shown in FIGURE A-3 (p. 83) and FIGURE A-4 (p. 83)) consists of three, 5/8"-diameter x 8-foot-long, copper-clad grounding rods. Install the rods in a radial 1200 star ("Y") configuration. Each rod must be installed in a true vertical position, at least 16 feet from the equipment.

NOTE:

Appendix B. Determining True North and wind sensor orientation

The orientation of the WindSonic "North Arrow Markers" is found by reading a magnetic compass and applying the site-specific correction for magnetic declination; where the magnetic declination is the number of degrees between True North and Magnetic North. Magnetic declination for a specific site can be obtained from a USGS map, local airport, or through a NOAA web calculator (Online magnetic declination calculator (p. 89)). A general map showing magnetic declination for the Conterminous United States is shown in FIGURE B-1 (p. 87).

FIGURE B-1. Magnetic declination for the conterminous United States (2015)

Declination angles east of True North are considered negative, and are subtracted from 360 degrees to get True North as shown FIGURE B-2 (p. 88) (0° and 360° are the same point on a compass). Declination angles west of True North are considered positive, and are added to 0 degrees to get True North as shown in FIGURE B-3 (p. 88).

For example, the declination for Longmont, CO (10 June 2006) is 9.67°, thus True North is 360° – 9.67°, or 350.33° as read on a compass. Likewise, the declination for McHenry, IL (10 June 2006) is -2.68°, and True North is 0° – (-2.68°), or 2.68° as read on a compass.

FIGURE B-2. A declination angle east of True North (positive) is subtracted from 360 (0) degrees to find True North

FIGURE B-3. A declination angle west of True North (negative) is subtracted from 0 (360) degrees to find True North

B.1 Online magnetic declination calculator

The magnetic declination calculator web calculator published by NOAA's Geophysical Data Center is available at: www.ngdc.noaa.gov/geomag/calculators/magcalc.shtml. This web page calculates declination based on the latitude and longitude. You can look up your site's latitude and longitude by entering the Zip Code or the Country and City, and then clicking the Get & Add Lat/Lon button (FIGURE B-4 (p. 89)).

Magnetic Declination Estimated Value

Declination is calculated using the most recent World Magnetic Model (WMM) or the International Geomagnetic Reference Field (IGRF) model. For 1590 to 1900 the calculator is based on the gufm1 model. A smooth transition from gufm1 to IGRF was imposed from 1890 to 1900. Declination results are typically accurate to 30 minutes of arc, but environmental factors can cause magnetic field disturbances.

Appendix C. PS24 24 Ah power supply with 10 x 12 inch enclosure

The PS24 Power Supply is typically used when a solar-powered WS-PRO2 transmits data using a wireless communications option. However, the PS24 can be used for any situation where a larger capacity battery is desirable.

C.1 PS24 components

The PS24 consists of a 24 Ah rechargeable battery in a 25 x 30 cm (10 x 12 in) environmental enclosure (FIGURE C-1 (p. 92) through FIGURE C-3 (p. 93)). Typically, the PS24 is ordered without a charging regulator and the PS100 or PS150 is moved from the station enclosure to the PS24 enclosure to serve as the charging regulator.

The battery should be recharged using AC power or solar power. An SP10 10-W solar panel, SP20 20-W solar panel, or wall charger is typically used to recharge the battery. The environmental enclosure is mounted to the WS-PRO2 pole using the mounting kit with hanger.

FIGURE C-3. Enclosure supply kit

C.2 PS24 installation

CAUTION:

The PS24 is purposely shipped without the battery mounted in its bracket. Do not install the battery until instructed to do so.

1. Place the top enclosure bracket on the pole at approximately 10 m (3 ft) above the bottom of the pole. The bracket should be installed with the hook side up, and facing north.
2. Slide the strut clamps into the bracket as shown in FIGURE C-4 (p. 94). Tighten the clamp so that it doesn't move.

CAUTION:

Do not over tighten the clamp!

FIGURE C-4. Strut clamps in brackets

1. Place the bottom strut clamp and bracket approximately 3 ~m (1 ft) below the top clamp. This clamp is installed with the hook side down. The bracket might have to be moved a little to accept the enclosure bracketing, so don't tighten the bracket yet. FIGURE C-5 (p. 94) shows the top and bottom brackets correctly positioned on the WS-PRO2 pole.

FIGURE C-6. Top clamp hook side up

1. The bottom enclosure bracket should slide between the top lip of the bottom strut mount bracket and the notch directly below. Move the bottom bracket if necessary, then bolt the bottom bracket down (see FIGURE C-7 (p. 96)).

CAUTION:

Do NOT over tighten the bottom bracket.

FIGURE C-7. Enclosure mounted on WS-PRO2 pole

1. The bottom enclosure bracket has a small metal locking mechanism. Push up on the small Phillips screw underneath the mechanism and slide it to the left. Once in place, put a small wire tie in the hole to the right of the locking mechanism (FIGURE C-8 (p. 97)).

NOTE:

To remove the enclosure from the bracketing, cut off the wire tie, slide the lock to the right, and lift the entire enclosure off the bracketing.

FIGURE C-9. Fully mounted solar panel

1. Place a blanket or box over the solar panel to prevent any voltage output.

2. Route the solar panel cable and power cable coming from the main WS-PRO2 enclosure into the conduit at the bottom of the PS24 enclosure.

TIP:

Leave a loop of all cables under the PS24 enclosure to act as a drip line. Cut both cables to whatever length you need. It doesn't hurt to leave a loop of cable inside the enclosure.

1. If this is a station retrofit, remove the PS100 or PS150 from the weather station enclosure and install it into the PS24 enclosure. Unplug the 7 Ah battery from the PS100 or PS150 and remove the battery from the battery compartment. The 7 Ah battery will not be used in the configuration.

2. Wire the charging source (solar panel or AC source) into the two CHG terminals on the CH150 or CHARGE terminals on the PS100 and PS150 (Table C-1 (p. 99)).

Table C-1: Solar panel or AC connections
Solar panel or AC wire color	Power supply connection terminal
Red CHG or CHARGE
Black CHG or CHARGE

NOTE:

Polarity makes no difference. Connect one wire per CHG terminal block.

1. If the charging source is a solar panel, remove the blanket or box from the solar panel once it's wired into the CH150, PS100 or PS150 regulator.

NOTE:

The charging LED (steady red on the PS100, or flashing green on the CH150 and PS150) indicates that the charging source (solar panel or AC) is providing a charging voltage to the battery. The battery will be charged regardless of the toggle switch position. The switch on the regulator controls the voltage going to the terminal blocks marked +12V on the PS100 and 12V on the CH150 and PS150.

FIGURE C-10. Procedure for installing and connecting battery

NOTE:

The power cable that carries the regulated 12 VDC power from the regulator in the external enclosure to the WS-PRO2 station enclosure has a two-pin connector on one end and tinned wires on the other.

1. Toggle the power switch on the regulator (CH100, PS100, CH150, or PS150) to the OFF position.
2. Wire the power cable to the regulator (Table C-2 (p. 101)).

Table C-2: Power cable-to-regulator connection
Wire color Regulator connection terminal
Red 12V or +12V
Black G

1. Plug the two-pin connector into the POWER connector on the back of the station.

2. Plug the connector on the BP24 24 Ah battery wiring harness into the only battery connector on the CH150 or PS150 (located adjacent to the charge ports) or into the Battery – Internal connector on the PS100 or the INT connector on the CH100.

NOTE:

Since the power coming into the enclosure is regulated power coming from the external enclosure, the wiring inside the WS-PRO2 station enclosure needs to be different than the standard wiring.

1. If this is a retrofit, inside of the ET station enclosure, wires come through the enclosure wall from the POWER connector on the back of the station that used to be wired into the charge ports of the PS100 or PS150. You have three options:

a. If you received a new POWER connector with your kit, remove the old POWER connector by removing the plastic nut on the back of the station that holds the POWER connector in place. Remove the old connector and replace it with the new one, placing the foam washer inside the enclosure. Tighten the plastic nut. Plug the plastic plug of the new POWER connector into the 12V port.
b. If you're working with the original POWER connector, connect the black wire of the POWER connector to the ground connector on the gray terminal strip, and the red wire to the 12V connector on the terminal strip. The wire and plug previously used with the PS100 or PS150 can be discarded
c. If you're experienced with electrical work, butt splice the wires of the POWER connector onto the wires from the harness assembly removed from the 7 amp hour battery (red to red and black to black). Plug the plastic plug into the 12V terminal.

1. An extra loop of ground wire was sent with the station. Use it to ground the enclosure to the grounding rod system. The external ground lug is mounted on the bottom left corner of the PS24 enclosure.

2. Move the switch to the ON position, and test the station.

3. After everything checks out, find the gray duct putty that was included in the enclosure supply kit. Seal the cable-entry conduit by placing putty on the inside and outside of it. Push the putty down into the cable entries.

CAUTION:

The enclosure needs to be sealed up tight, so don't be stingy with the putty.

1. Put both bags of desiccant inside of the enclosure.

2. Stick the humidity indicator card on a wall inside of the enclosure.

CAUTION:

Pink on the humidity indicator card means it's time to change the desiccant. Change the desiccant at least every year. However, it's often wise to change the desiccant every six months.

1. Close the lids on the external enclosure and the WS-PRO2 enclosure.
