during the fan motor runs.
Error Decision
Conditions
When overcurrent is detected (Detecting overcurrent 4 times will shut down the system).
When the fan revolutions fall below a given level for a period of 6 seconds while in fan motor
rotation mode (Detecting shortage of revolutions will shut down the system).
