Modulating Cooling Device
The Modulating Cooling Device signal can be confi gured for either a
0-10 VDC, 2-10 VDC, or 1.5-5.0 VDC output signal when programming
the controller. The output signal can also be confi gured for either Direct
Acting or Reverse Acting operation as required by your application. This
signal output would normally be connected to a Modulating Chilled
Water Valve or Copeland Digital Scroll™ Compressor Controller.
See Figure 29 below for detailed wiring of the Modulating Cooling
Device when using a Chilled Water Valve. When this output is used
with a Copeland Digital Scroll™ Compressor, the Suction Line Pressure
Transducer must be wired to the Copeland Digital Scroll™ Compressor
Controller instead of the VCM-X E-BUS Controller, and the Modulat-
ing Cooling Output signal must be confi gured for a 1.5 to 5.0 VDC
output signal. For Copeland Digital Scroll™ Compressor wiring details,
see Figure 19, page 22.
Warning: It is very important to be certain that all wiring is
correct as shown in the wiring diagram below. Failure to observe the
correct polarity could result in damage to the Modulating Cooling
Device or the VCM-X Expansion Module.

WARNING!!
Observe Polarity! All boards must be wired with GND-to-GND and 24VAC-to-24VAC. Failure to
observe polarity will result in damage to one or more of the boards. Expansion Modules must
be wired in such a way that the expansion modules and the controller are always powered
together. Loss of power to the expansion module will cause the controller to become
inoperative until power is restored to the expansion module.

(Configurable)
Note:
1.) The Modulating Cooling
Device Used Must Be Capable Of
Accepting Either A 0-10 VDC, 2-
10 VDC, Or 1.5-5.0 VDC Input.
The Modulating Cooling Output
Voltage Is User- Configurable For
These Voltages. This Voltage
Output Must Be Configured When
You Are Setting Up The VCM-X
Controller’(s) Operating
Parameters.
2.) The Modulating Cooling
Device Used On The VCM-X
Controller Must Have (1) Relay
Output Configured In Order To
Enable The Modulating Cooling
Device's Sequence. This Relay
Output Must Be Configured When
Setting Up The VCM-X Controller
