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.

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 will need to
be replaced.


Code 125 – Controller fault
This fault indicates that the charge control board is failing a self-test needed to insure it’s integrity at
performing safety functions, such as RAM test or ROM test. If cycling power several times does not
clear the fault, the charge control board will need to be replaced.

Soft faults

Code 131 – Ground Fault (GF) maximum retry per charge cycle exceeded
This fault indicates that the controller has detected more than 4 ground faults in a charge cycle
meaning that the number of allowed retries has been exceeded. The charging plug must be removed
from the electric vehicle (EV) socket in order to clear this fault.

Code 132 – Ground Fault (GF) self-test failed
The controller’s GF protection circuit is verified every time a vehicle is connected. This fault indicates
that the self-test has failed. The charging plug must be removed from the EV socket in order to clear
this fault.
