Diagnostic Features
The LED on the CXM board advises the technician of 
the current status of the CXM control. The LED can 
display either the current CXM mode or the last fault in 
memory if in test mode. If there is no fault in memory, 
the LED will fl ash Code 1 (when in test mode). 
CXM Control Start-up Operation
The control will not operate until all inputs and safety 
controls are checked for normal conditions. The 
compressor will have a 5 minute anti-short cycle delay 
at power-up. The fi rst time after power-up that there is a 
call for compressor, the compressor will follow a 5 to 80 
second random start delay. After the random start delay 
and anti-short cycle delay, the compressor relay will 
be energized. On all subsequent compressor calls, the 
random start delay is omitted.
