When The
Suction
Pressure
Transducer Is
Used
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.

Suction Pressure
Note:
1.) If Unit Has Dehumidification
Option And Copeland Digital
Compressor
, Wire
Suction Pressure Transducer
Is Not Used
Directly
To VCM-X Expansion Module As Shown.
Caution:
1.) The Schraeder Port Used For Installation
Of The Suction Pressure Transducer Should
Be Located In A Vertical Portion Of The
Suction Line To Prevent Refrigerant Oil
From Accumulating In The Sensor.
Note:
1.) If Unit Has Dehumidification Option
And Copeland Digital Compressor Is Used,
Wire Suction Pressure Transducer To
Copeland Controller As Shown On
Following Page.
2.) AO3 Output Voltage Must Be
Configured For 1.5 - 5 VDC Operation
When You Are Setting Up The VCM-X
Controller Operating Parameters For A
Copeland Digital Compressor.
