7. ALARMS & ERRORS
7.1 FREQUENCY MONITORING AND ERROR DETECTION
The FCAx3 dynamically measures the frequency of the mains supply and reacts accordingly. If the mains supply frequency is
too low or too high, the FCAx3 will then disconnect the compressor and indicate an error signal through the LEDs. The FCAx3
can auto-recover once the frequency is within acceptable limits.

Note: The above illustration assumes that the Mains voltage RMS value is good and there is cooling demand, hence the
compressor comes on after the intelligent time delay is over.
7.2 REGULATION PROBE (PROBE#1) ERROR DETECTION
The FCAx3 will report an error code through the LEDs indicating a sensor fault if it happens. Depending on customer
preferences the FCAx3 will either:
Scenario One: Detect the fault and disconnect the compressor until the problem is resolved and then the system resumes
normal operation.
