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 first 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.
