FAULT VFD Gateway; Check VFG
Module and Power.
VFD COMMUNICATIONS 170Loss of DPI Comm with
FAULT VFD Gateway; Check VFG to
VFD Comm.
PRIMARY CAUSE
Check sensor resistance or voltage drop.
Check for proper wiring.
Check for excessive starts.
Check Comp Discharge Alert setting in SETUP1
screen.
Check humidity sensor wiring on CCM connec-
tors J3 and J5. CCM switch SW2-1 must be in
"OFF" position.
Check Humidity Sensor Input in Controls Test.
The communication between the VFD Gateway
