POSSIBLE CAUSE

Defective control fuse.

•Check control fuse for open circuit, replace fuse, if necessary.

Defective control.

•Replace controller unit.

Note: Repeated “charging/discharging” the capacitors during troubleshooting will cause status code 51. Also “do not” connect any loads to the load side of the line contactor.
