Soft Faults - GE WattStation Installation And User Manual

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.

7.3 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.
Note: The GF protection circuit is also verified during the controller's power-up self-test
sequence. If the GF self-test fails at this time, the fault will behave like a hard fault, and cycling
AC power will be required to clear the fault. If the problem persists, verify that the GF CT (with
the black and white body) leads (red and black) are connected to J10 and the self-test wire
loop leads (same color) are connected to J19. Polarity of these leads does not matter.
Code 133 – Overcurrent trip
The charge controller performs a secondary overload protection feature to prevent the
internal fuses or upstream branch feeder breaker from tripping in the case of a defective
vehicle. This fault indicates that the controller has detected an overcurrent condition and
tripped. The charging plug must be removed from the EV socket in order to clear this fault.
With power removed, the fuses should also be checked as some high level fault conditions are
too fast for this secondary protection to prevent the fuses from blowing.
Code 134 – Pilot diode test failed
The SAE J1772 standard requires a diode to be present in the vehicle's pilot circuit. Prior to
every charge cycle, the charge controller checks for the presence of this diode, and if it is not
there will issue this fault. The charging plug must be removed from the EV socket in order to
clear this fault.
Code 135 – Contactor won't close
Every time the charge controller attempts to close the contactor, it checks immediately
afterwards for the auxiliary feedback on J11 pin 5 to change state. If the contactor auxiliary
feedback does not change state, this fault will be issued. The charging plug must be removed
from the EV socket in order to clear this fault.
