Faults are classified into three different categories
Hard Faults – AC power must be cycled in order to clear these faults. If the first power cycle
does not clear the fault please cycle the power again and the fault should clear if the condition
causing the fault has been resolved
Soft Faults – The vehicle must be disconnected in order to clear these faults.
Alarms – These can clear automatically if the condition causing the alarm goes away.

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 pilot is correctly
wired to connector J7. The pilot line should be connected to J7-1 and chassis ground to J7-2.
Code 112 – Invalid configuration
This fault indicates that the 8-position DIP switch (S6) on the WattStation charge control board
is set incorrectly. The charge control board is used in several GE electric vehicle charging
station products, and these settings are used to configure it to operate properly per product.
For the NEMA Networked Wallmount WattStation TM the switch settings should be, from left to
right:
Position 1 2 3 4 5 6 7 8
Setting Closed Closed Closed Open Closed Closed Closed Closed
Code 113 – No socket detected on proximity input
This fault is not applicable to NEMA Networked Wallmount WattStation.
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
normally-closed auxiliary feedback of the contactor. 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
contact does not operate correctly. It is suggested to check for the wiring problems first as a
contactor weld should be a rare event.
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.
