What does the state of the fault light on my PhaseAdept module mean?
There are four states your Fault light on your PhaseAdept module can show:
Off- No Fault
Solid- Inrush current threshold exceeded or short circuit detected
Slow blink (1 per second)- Voltage threshold exceeded
Fast blink (1 per half second)- temperature threshold exceeded
Note: Slow blink and fast blink state were incorrectly stated as slow Temp and Fast Voltage in the CEM3
If you are experiencing a fault some things to try would be:
Solid- Check wiring for short circuits and determine if inrush current is excessive
Slow blink (1 per second)- Make sure you are not using magnetic loads
Fast blink (1 per half second)- Make sure airflow in the rack is good and the module is free of debris
PhaseAdept Modules Protect Themselves
In event of a short circuit, the PhaseAdept Dimmer module shuts down to prevent damage. The module allows inrush current for one cycle and will shut down if current at the inrush current threshold persists for more than one cycle or if current exceeds the inrush current threshold. *Variants of PhaseAdept Modules have different inrush current thresholds.
The module also shuts down in the presence of voltage spikes caused by a magnetic load. To recover from this state, turn the circuit breaker off and back on again, change the phase switch to forward, or set the control level to zero and then set the control level to another value.
