7 Trouble-shooting

7.1 Fault Icon codes

When the DuraStation™ controller experiences an alarm or fault it will display a fault code on the display.
Alarms and faults are classified into three different categories:
Hard faults – These problems are generally considered to be caused by an issue within the station,
therefore the AC power must be cycled in order to clear these faults.
Soft faults – These problems are generally considered to be caused by an issue with the vehicle,
therefore the vehicle must be disconnected in order to clear these faults. If not, explore potential
problems within the station (e.g. ground fault caused by damaged charge cord or wiring problem with
the station).
Alarms – These codes can clear automatically if the condition causing the alarm goes away (e.g.
undervoltage).

7.2 Hard Faults

Code 111 – Pilot out of range at startup
This fault indicates that the controller has measured an illegal voltage on the pilot interface during the
power-up self-test sequence. Check the wiring and confirm that the pilot is correctly wired to
connector J7. The pilot line should be connected to J7-1 and chassis ground to J7-2.
Codes 112, 113
These faults are no longer used ... should they occur please contact GE technical support.
Code 114 – Contactor welded
This fault can be set during power-up self-test if AC voltage is not detected at the J11 pin 5 input to
the controller. The fault can also be set if the contactor does not open when commanded by the
controller to do so, or if the normally-closed auxiliary switch does not operate correctly. It is
suggested to check for wiring or aux switch problems first as contactor weld is very uncommon.
Code 115 – Controller Non-Volatile Memory (NVM) corrupt
This fault would be set during the controller's power-up self-test sequence, indicating that the non-
volatile memory used to store charging state information was corrupt. If cycling power several times
does not clear the fault, the charge control board will need to be replaced.
Code 121 – Temperature sensor reading out of range
This fault would be set during the controller's power-up self-test sequence, indicating that the on-
board temperature sensor is defective. If cycling power several times does not clear the fault, the
charge control board will need to be replaced.
Code 122 – Invalid MAC address
This fault would be set during the controller's power-up self-test sequence, indicating that the
Ethernet port on the charge control board has an invalid MAC address. If cycling power several
times does not clear the fault, the charge control board will need to be replaced.
Code 124 – Communication Controller Failure
If cycling power several times does not clear the fault, the communication control board (a.k.a. SBC)
will need to be replaced.
