Only inclined incident light in the front and by the socket on the charging station (not indication green/red/blue)

Cause of error
CCU does not deliver 12 V to the indicator LED at the top of the charging station.

Action 1
Check that the CCU has voltage (24 V). Indicated by flashing diodes (green/yellow/red) in the upper left corner of the CCU (next to the quick connector for the supply):

• If LEDs do not flash, check that the power supply delivers 24 V. If it has voltage but does not light, replace the CCU.
• If all LEDs are solid, the CCU must be replaced with a new one.

Action 2
Check that the 4-way quick connector from the CCU to the top card is correctly connected at the bottom right of the CCU.

Cause of error  
Alt. 1: Control fuse switched off at bottom of charging station
Alt. 2: 24V power supply switched off (Green LED [DC OK] on power supply off).

Action 1
Make sure the control fuse (1-pin 10A) is switched on.

Action 2
Make sure the power supply receives 220V AC at the L & N ports.

Action 3
Disconnect the red/black cabling from "+/-" ports on the power supply. 
 

Action 4
If the power supply jump starts, it has detected an earth fault from the DC-powered component (controllers, top card, router/switch, etc.) in the charging station.

If [DC OK] remains off, replace the power supply.
