Faults
gives an overview of possible fault codes. Conditions such as overvoltages can trip faults and alarms. It is
important to distinguish between faults and alarms to determine the proper corrective actions. When the regenerative unit
detects a fault, the ALM indicator LED lights, the fault code appears on the digital operator, and the fault contact
MA-MB-MC triggers. An alarm is present if the ALM LED blinks and the fault code on the digital operator flashes.

<1> Displayed as CPF00 when occurring at regenerative unit power up. When one of the faults occurs after successfully starting the regenerative
unit, the display will show CPF01. Displayed as CPF20 when occurring at regenerative unit power up. When one of the faults occurs after
successfully starting the regenerative unit, the display will show CPF21.
