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.
