DIN Rail Motor Control: DIN-2MC2

Introduction

The DIN-2MC2 is a 2-channel motor control module designed to provide control of bidirectional motors for drapes, shades, projection screens, lifts, skylights, and gates. Each channel supports up/down or open/close control of a conventional three-wire bidirectional type motor up to 1/2 HP at voltages up to 240 Volts. Built-in timing and interlock logic make it easy to program the DIN-2MC2 for failsafe operation.

Features and Functions

• Dual-channel bidirectional motor control
• Supports 120 to 240 Volt 50/60 Hz
- Override input
• Cresnet ^® communications
- Setup via front panel or software
• Programmable functionality via DIN-AP2
- 6M wide DIN rail mounting

Override Input

An override input is provided to allow an external contact closure to momentarily override the control system program and set each channel output to its override preset state. States can be set and saved locally from the front panel, or remotely via software.

DIN Rail Installation

The DIN-2MC2 is designed to snap onto a standard DIN rail for installation in a wall mount enclosure. Wiring connections are made using screw terminals positioned along the top and bottom, clearly accessible from the front for easy installation and servicing. All setup controls and indicators are positioned on the center front panel. When installed in an enclosure utilizing 45 mm cutouts, the DIN-2MC2's front panel stays accessible while the connections are concealed.

Cresnet®

The DIN-2MC2 communicates with a DIN-AP2 2-Series Automation Processor, or other Crestron ^® 2-Series control system, via the Cresnet control network. A pair of Cresnet ports is provided on the DIN-2MC2 allowing for easy daisy-chaining of several DIN Rail Series automation control modules.

Earliest Version Software Requirements for the PC

NOTE: Crestron recommends that you use the latest software to take advantage of the most recently released features. The latest software is available from the Crestron website.

Crestron has developed an assortment of Windows ^® -based software tools to develop a Cresnet system. You can create a program to control the DIN-2MC2 using the Crestron programming tools Crestron SystemBuilder ^™ , D3 Pro ^® or SIMPL Windows. Customers whose focus is on lighting systems may prefer to use the D3 Pro software since it is designed especially for creating lighting and environmental system control applications. Customers already familiar with SIMPL Windows who are including a lighting system as part of an overall control system project may prefer to continue using SIMPL Windows. For the minimum recommended software versions, visit the Version Tracker page of the Crestron website (www.crestron.com/versiontracker).

Programming with Crestron SystemBuilder

Crestron SystemBuilder is the easiest method of programming but does not offer as much flexibility as SIMPL Windows. For additional details, download SystemBuilder from the Crestron website and examine the extensive help file.

Programming with D3 Pro

Crestron's D3 Pro lighting software provides all the tools necessary to create a complete Crestron lighting system for residential applications. The lighting system includes the control system logic program, touchpanel projects and keypad programming, documentation and real-time lighting adjustment capabilities.

As with all Crestron software, D3 Pro provides extensive right-click and drag-and-drop functionality in addition to convenient keyboard shortcuts for frequently used functions and commands.

Programming is organized into six system Views of the lighting system, each providing a moveable toolbox of devices such as interfaces, fixtures and control modules. You can add a device to your system simply by selecting it from one of the toolboxes and dragging it to a room. The available toolboxes differ depending on the View but all Views include a "General" toolbox that allows you to add areas and rooms at any time.

Programming with SIMPL Windows

NOTE: While SIMPL Windows can be used to program the DIN-2MC2, it is recommended to use SystemBuilder for configuring a system.

SIMPL Windows is Crestron's premier software for programming Crestron control systems. It is organized into two separate but equally important “Managers”.

Configuration Manager

Configuration Manager is the view where programmers “build” a Crestron control system by selecting hardware from the Device Library.

1. To incorporate the DIN-2MC2 into the system, drag the DIN-2MC2 from the Lighting | Lighting (DIN-Rail Series) folder of the Device Library and drop it in the System Views.

Locating the DIN-2MC2 in the Device Library

1. The system tree of the control system displays the device in the appropriate slot with a default Net ID as shown in the following illustration.

C2Net Device, Slot 5

1. Additional DIN-2MC2 devices are assigned different Net ID numbers as they are added.

2. If necessary, double click a device to open the "Device Settings" window and change the Net ID, as shown in the following figure.

"Device Settings: Crestron DIN-2MC2" Window

1. The ID code specified in the SIMPL Windows program must match the Net ID of each unit. Refer to “Identity Code” on page 9.

Program Manager

Program Manager is the view where programmers “program” a Crestron control system by assigning signals to symbols.

The symbol can be viewed by double clicking on the icon or dragging it into Detail View. Each signal in the symbol is described in the SIMPL Windows help file (F1).

Example Program

An example program for the DIN-2MC2 is available from the Crestron website (www.crestron.com/exampleprograms).

Uploading and Upgrading

Crestron recommends using the latest programming software and that each device contains the latest firmware to take advantage of the most recently released features. However, before attempting to upload or upgrade it is necessary to establish communication. Once communication has been established, files (for example, programs or firmware) can be transferred to the control system (and/or device). Finally, program checks can be performed (such as changing the device ID or creating an IP table) to ensure proper functioning.

Establishing Communication

Use Crestron Toolbox for communicating with the DIN-2MC2; refer to the Crestron Toolbox help file for details. There is a single method of communication: indirect communication.

Indirect Communication

graph LR
    A["PC Running Crestron Toolbox"] <-->|Serial, Ethernet or USB| B["Control System"]
    B <-->|Cresnet| C["DIN-2MC2"]

DIN-2MC2 connects to control system via Cresnet:

1. Establish communication between the PC and the control system as described in the latest version of the 2-Series Control Systems Reference Guide (Doc. 6256) which is available for download from the Crestron website (www.crestron.com/manuals).
2. Use the Address Book in Crestron Toolbox to create an entry for the DIN-2MC2 using the expected communication protocol (indirect). Select the Cresnet ID of the DIN-2MC2 and the address book entry of the control system that is connected to the DIN-2MC2.
3. Display the DIN-2MC2's "System Info" window (click the icon); communications are confirmed when the device information is displayed.

Programs and Firmware

Program or firmware files may be distributed from programmers to installers or from Crestron to dealers. Firmware upgrades are available from the Crestron website as new features are developed after product releases. One has the option to upload programs via the programming software or to upload and upgrade via the Crestron Toolbox. For details on uploading and upgrading, refer to the SIMPL Windows help file or the Crestron Toolbox help file.

SIMPL Windows

If a SIMPL Windows program is provided, it can be uploaded to the control system using SIMPL Windows or Crestron Toolbox.

Firmware

Check the Crestron website to find the latest firmware. (New users may be required to register to obtain access to certain areas of the site, including the FTP site.)

Upgrade DIN-2MC2 firmware via Crestron Toolbox.

1. Establish communication with the DIN-2MC2 and display the "System Info" window.
2. Select Functions | Firmware... to upgrade the DIN-2MC2 firmware.

Program Checks

Using Crestron Toolbox, display the network device tree (Tools | Network Device Tree) to show all network devices connected to the control system. Right-click on the DIN-2MC2 to display actions that can be performed on the DIN-2MC2

Operation

NET ID

Use the NET ID buttons to change the Net ID of the DIN-2MC2. For more information on setting the Net ID, refer to “Identity Code” on page 9.

Manual Control

Each of the DIN-2MC2 outputs can be in one of three states: OPEN, CLOSE, or STOP. When an output is in the OPEN state, the OPEN LED illuminates. When an output is in the CLOSE state, the CLOSE LED illuminates. When an output is in the STOP state, neither of the output LEDs illuminate.

The state of each output can be manually controlled from the buttons on the front panel.

If an output is in the STOP state, press and release the OPEN or CLOSE button to activate the OPEN or CLOSE state. The corresponding LED illuminates to indicate the state of the output. The LED stays lit until the programmable “max time” parameter is reached. Additionally, the NET ID display briefly indicates the state of the output (“OP” for open, “CL” for close).

If an output is in the OPEN or CLOSE state, pressing the OPEN or CLOSE button places the output in the STOP state. Neither of the LEDs illuminate. However, the NET ID display briefly indicates the state of the output (“St” for stop).

An output left in the OPEN or CLOSE state reverts to the STOP state after a programmable timeout.

NOTE: The control system program may change the state of the output if the Override mode is not enabled.

Override Mode

The Override mode overrides the control system program and sets the motor outputs to the saved override settings. For instructions on saving override settings, refer to “Save Override Settings” on page 21.

To enable the Override mode, press and release the OVR button. The OVR LED flashes slowly.

NOTE: If the Override mode was enabled from an external device (i.e., a contact closure is present on the OVERRIDE terminals), the OVR LED flashes quickly. Pressing the OVR button has no effect.

To disable the Override mode, press the OVR button again. The OVR LED extinguishes and the motor outputs go to their STOP states.

NOTE: If override settings have not been saved, the factory default setting is for the motor outputs to remain unaffected when the Override mode is enabled.

Save Override Settings

The state of each output can be saved as an override setting which can be automatically recalled when the Override mode is enabled.

NOTE: The control system program has a setting that can prevent locally saving the override settings. If this setting is enabled, the display shows “Er” when trying to save the override settings. For more information, refer to the SIMPL Windows help file.

To save the state of an output as an override setting:

1. Press the OPEN or CLOSE control button to activate the desired function on one or both motor outputs. To leave an output unaffected by the Override mode, leave the output in the STOP state.
2. Press and hold the OVR button for three seconds. The OVR LED blinks to indicate new override settings have been stored. Motor outputs that were “closing” are set to go to the “Full Close” position when the Override mode is enabled. Motor outputs that were “opening” are set to go to the “Full Open” position when the Override mode is enabled. Motor outputs that were “stopped” are unaffected when the Override mode is enabled.

Reset

To reboot the DIN-2MC2, press the RESET button. The motor outputs are set to the state currently specified by the control system program. If the control system does not provide a setting, the outputs are set to the last-known state.

Check Network Wiring

Use the Right Wire

In order to ensure optimum performance over the full range of your installation topology, Crestron Certified Wire and only Crestron Certified Wire may be used. Failure to do so may incur additional charges if support is required to identify performance deficiencies because of using improper wire.

Calculate Power

CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to do so could cause equipment damage or void the Crestron warranty.

CAUTION: Provide sufficient power to the system. Insufficient power can lead to unpredictable results or damage to the equipment. Please use the Crestron Power Calculator to help calculate how much power is needed for the system (www.crestron.com/calculators).

When calculating the length of wire for a particular Cresnet run, the wire gauge and the Cresnet power usage of each network unit to be connected must be taken into consideration. Use Crestron Certified Wire only. If Cresnet units are to be daisy-chained on the run, the Cresnet power usage of each network unit to be daisy-chained must be added together to determine the Cresnet power usage of the entire chain. If the unit is home-run from a Crestron system power supply network port, the Cresnet power usage of that unit is the Cresnet power usage of the entire

run. The wire gauge and the Cresnet power usage of the run should be used in the following equation to calculate the cable length value on the equation's left side.

Cable Length Equation

$$ L < \frac {4 0 , 0 0 0}{R \times P} \quad \boxed { \begin{array}{l} \text {Where: L = Length of run (or chain) in feet} \ R = 6 \text {Ohms (Crestron Certified Wire: 0.75 mm} ^ {2} (1 8 \mathrm{AWG})) \ P = \text {Cresnet power usage of entire run (or chain)} \end{array} } $$

Make sure the cable length value is less than the value calculated on the right side of the equation. For example, a Cresnet run using 0.75 mm^2 (18 AWG) Crestron Certified Wire and drawing 20 watts should not have a length of run more than 101 meters (333 feet). Cresnet-HP wire cannot be used.

NOTE: All Crestron certified Cresnet wiring must consist of two twisted pairs. One twisted pair is the +24V conductor and the GND conductor and the other twisted pair is the Y conductor and the Z conductor.

Strip and Tin Wire

When daisy-chaining Cresnet units, strip the ends of the wires carefully to avoid nicking the conductors. Twist together the ends of the wires that share a pin on the network connector and tin the twisted connection. Apply solder only to the ends of the twisted wires. Avoid tinning too far up the wires or the end becomes brittle. Insert the tinned connection into the Cresnet connector and tighten the retaining screw. Repeat the procedure for the other three conductors.

Add Hubs

Use of a Cresnet Hub/Repeater (DIN-HUB) is advised whenever the number of Cresnet devices on a network exceeds 20 or when the combined total length of Cresnet cable exceeds 914 meters (3000 feet).
