DXM2 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.
