8 Trouble shooting
8.1 Fault Icon flash codes
Faults and alarms will cause the LED ring to illuminate red (unless configured to another color using the
configuration tool) and the red fault icon will flash one or more fault codes. All codes are three (3) digits and
no digit is more than 5. The minimum possible code is 111 and the maximum possible code is 555. There
may be more than one flashing code and in that case they will just alternate. For example, codes 123 and
231 would flash as follows:
Blink – pause – Blink-Blink – pause – Blink-Blink-Blink – long pause,
Blink-Blink – pause – Blink-Blink-Blink – pause – Blink – long pause,
Blink – pause – Blink-Blink – pause – Blink-Blink-Blink – long pause,
Blink-Blink – pause – Blink-Blink-Blink – pause – Blink – long pause, and so on.
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.
8.2 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 WattStation
Pedestal 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 WattStation Pedestal.
