C: Compressor Non-Start:
If the compressor does not start, the Module will stop the starting process, & attempt a re-
start every 60 seconds.
D: Compressor Speed Too Low:
If the compressor speed falls below 1900 RPM the Module will stop the compressor.
E: Fan Protection:
If the current draw across the fan terminals exceeds 0.7 amps 12v dc, the compressor will
be stopped & a re-start attempted every 60 seconds.
F: Module Overheat:
If the heat sink on the module exceeds a preset temperature, the compressor will be
stopped & will be re-started when normal operating temperatures are resumed.
G: 4 Alarm Indicator:
A LED may be installed across the + & D terminals of the Module to indicate a failure
condition as follows:
LCD will “Blink” up to 5 times every 5 seconds.
1 Blink; Supply voltage low, below 10.4v (22.8)
2 Blinks; Excessive load on fan terminals, above 1.0 amps
3 Blinks; Compressor non-start – Refrigerant pressure too high
4 Blinks; Compressor speed below 1850 RPM
5 Blinks; Module heat-sink temp too high. Re-sets on cool-down. IE: Module too hot.
NOTE ONE
After power is applied to the Module there may be a delay of up to 60 seconds before the
compressor starts
