DIN Rail Motor Control
Installation and Operation Guide
The Crestron 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 to1/2 HP at voltages up to 240 Volts. Built-in
timing and interlock logic make it easy to program the DIN-2MC2 for failsafe operation.

WARNING: To avoid fire, shock, or death, turn off the power at the circuit breaker or
fuse and test that the power is off before wiring!
CAUTION: This equipment is for indoor use only. Mount in a well-ventilated area. The
ambient temperature must be 0º to 40 ºC (32º to 104 ºF). The relative humidity must be
10% to 90% (noncondensing).
NOTE: Install and use this prodct in accordance with appropriate electrical codes and
NOTE: A licensed electrician should install this product.
NOTE: When installing in an enclosure, group high-voltage devices separately from
low-voltage devices.
Install the DIN-2MC2
The DIN-2MC2 installs on a DIN rail.
1. Use a flat object (e.g., a flat-head screwdriver) to pull the DIN rail release
2. With the top of the unit tilted down, place the DIN-2MC2 against the bottom of the
DIN rail.
3. Tilt the top of the DIN-2MC2 toward the DIN rail until it is secure on the top edge of
the rail. Push the DIN rail release upward to lock the DIN-2MC2 into place.

Make the necessary connections as shown below. Apply power after all connections
have been made. When making connections to the DIN-2MC2, use Crestron power
supplies for Crestron equipment.
WARNING: Prior to connecting the device, turn off the power at the circuit breaker.
Failure to do so may result in serious personal injury or damage to the device. Restore
the power after all the connections have been made.
CAUTION: Connecting this device to the wrong type of load or short-circuiting the
load can cause severe product damage. Test each load to identify a short-circuit
condition prior to wiring the load to the module.
NOTE: Cresnet® HP wire cannot be used.
NOTE: Strip the ends of the wires approximately 1/4 in (6 mm). Use care to avoid
nicking the conductors. Twist together the ends of the wires that share a connection.
Apply solder only to the ends of the twisted wires. Avoid tinning too far up the wires or
the end becomes brittle.
NOTE: High-voltage connections accept 2.5 mm2 (12 AWG) wire. Wire should be
stripped to 8 mm (1/3 in). Tighten terminal blocks to 0.5 Nm (5 in-lbs).
NOTE: Each channel of the DIN-2MC2 may be fed from a separate circuit breaker or a
single, shared breaker.
NOTE: Use copper wire only. For high-voltage connections, use wire rated for at least
75 ºC (167 ºF).
NOTE: Ensure the unit is properly grounded by connecting the chassis ground lug to
an earth ground (building steel).

Remove the DIN-2MC2
To remove the DIN-2MC2 from the DIN rail, use a flat object (e.g., a flat-head
screwdriver) to pull the DIN rail release and tilt the bottom of the DIN-2MC2 away from
the DIN rail.
NOTE: Certain third-party DIN cabinets provide space for an informational label
between each DIN rail row. Crestron’s Engraver software (version 4.0 or later) can
generate appropriate labels for all Crestron DIN rail products.

The Net ID of the DIN-2MC2 has been factory set to 85. The Net IDs of all devices in the
same system must be unique. The Net ID can be changed from the front panel of the
DIN-2MC2 or from a personal computer via Crestron Toolbox™ software.
Set the Net ID using the front panel.
1. Press the SETUP button to enter Setup mode. The SETUP LED illuminates.
2. Press the left and right buttons under the NET ID display to change the Net ID.
NOTE: The DIN-2MC2 leaves Setup mode after 10 seconds of inactivity and
reverts to the previously set Net ID.
3. When the desired Net ID displays, press the SETUP button to exit Setup mode. The
SETUP LED extinguishes.
NOTE: If an invalid Net ID is set (i.e., 00, 02, FF), “Er” shows on the NET ID
display, and the DIN-2MC2 reverts to the previously set Net ID.
A small Net ID label is provided on the DIN-2MC2 to document the unit’s Net ID in the
case where power is not available. Apply a mark over the digits that correspond to the
assigned Net ID.
NET ID Label (“3C” Shown)
NOTE: Before using the DIN-2MC2, ensure the device is using the latest firmware.
Check for the latest firmware for the DIN-2MC2 at Load
the firmware onto the device using Crestron Toolbox.
The DIN-2MC2 can be controlled via its front panel as well as from a control system. The
following local controls are available.
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.
The following table provides corrective actions for possible trouble situations. If further
assistance is required, please contact a Crestron customer service representative.

NOTE: The control system program may change the state of the output if the Override
mode is not enabled.
Establish Override Mode Levels
Override mode disables the control system program and sets all of the output states to
the stored override values. The state of each output can be saved as an override setting,
which can be automatically recalled when Override mode is enabled.
NOTE: The control system program has a setting that can prevent locally saving the
override state. If this setting is enabled, the display shows “Er” when trying to save
override states. For more information, refer to the SIMPL Windows help file.
To save the motor state as an override setting, press the OPEN or CLOSE button to
activate the desired function on one or both motor outputs and then press and hold the
OVR button for three seconds. The OVR LED blinks to indicate the new override setting
has been stored. Motor outputs that were closing are set to go to the full close position
and motor outputs that were opening are set to go to the full open position when
Override mode is enabled.
Toggle Override Mode
To enable Override mode, press the OVR button. The OVR LED flashes slowly. Override
mode can also be toggled via a remote contact closure attached to the OVERRIDE port.
NOTE: If Override mode was enabled from an external device (i.e., a contact closure
connected to the OVERRIDE port), the OVR LED will flash quickly when the local OVR
button is pressed. Pressing the local OVR button has no effect when Override mode
was toggled via the remote connection.
To disable Override mode, press the OVR button again. The OVR LED extinguishes and
the outputs return to the states set by the control system program.
NOTE: If override levels have not been saved, the factory default override level is
Reboot the DIN-2MC2
To reboot the DIN-2MC2, press the RESET button. The outputs will be set to the states
currently specified by the control system program. If the control system does not provide
any values, the outputs will be set to the previously set values.
