Soft Faults - GE DuraStation Operation And Maintenance

DuraStation™ EV Charger User Manual
Code 125 – Charge 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 (the 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. The 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. It is
possible to disable the pilot diode test using the local configuration tool (see section 4.2.4). Note that
GE recommends disabling simplified charging if the diode test is disabled.
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.
Code 142 – Fan required to charge
The SAE J1772 standard has an accommodation for electric vehicles which have batteries that
Potentially outgas during charging. These vehicles will take the pilot to State D (i.e. 3V) instead of the
normal State C (6V) to indicate they are ready for charge.
If used indoors, facility ventilation is required to charge these types of vehicles. It is possible to allow
State D charging using the local configuration tool (see section 4.2.4). The charging plug must be
removed from the EV socket in order to clear this fault.
