Mermaid REFRIGERATION/FREEZER Compressor Non-Start, Compressor Speed Too Low, Fan Protection

Page 6

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.
