ALARM CODES
LED
Neutral and Voltage terminal connections are incorrect.
Voltage terminal connections are in counter-clockwise direction
Voltage terminal connections are wrong
Current transformer connections for phase 1 are wrong or fist capacitor step is defected
Current transformer connections for phase 2 are wrong or first capacitor step is defected
Current transformer connections for phase 3 are wrong or first capacitor step is defected
Excessive harmonic exists in the system
Voltage value of the system is increased
Compensation Error
Compensation Error
Defected 1st capacitor step or loads are too variable.
