Code 154 – Pilot transition violation
This alarm indicates that the charge controller has detected a transition from State A (12V) to State C
(6V) on the vehicle Pilot circuit input (J7). Unless it is specifically configured to allow the State A to
State C transition (bypassing State B) by enabling non-SAE 1772 compliant mode charging in the
configuration tool, the charge controller will issue this alarm. The alarm will clear automatically when
the Pilot is returned to State A.
Code 155 – Pilot 0V feedback
This alarm indicates that the charge controller has detected a zero volts on the vehicle Pilot circuit
input. The charge controller itself does not have the capability to take the pilot to zero volts, therefore
check for problems in the wiring to J7. If necessary measure the resistance of the pilot conductor (J7
pin 1) to chassis ground (J7 pin 2). Remember problems could be on the vehicle side as well. This
alarm will clear automatically when the short circuit condition is removed.
Code 211 – Overvoltage
This alarm indicates that the charge controller has detected AC line voltage in excess of 270 Vac. This
alarm will only set when charging or trying to charge. It will not set during standby operation or when
the vehicle is still connected after charging completed. When the overvoltage alarm sets, the alarm
condition will persist for a minimum of one minute, after which time the alarm will clear when voltage
drops to 265 Vac or below.
Code 212 – Undervoltage
This alarm indicates that the charge controller has detected AC line voltage below 170 Vac. This
alarm will only set when charging or trying to charge. It will not set during standby operation or when
the vehicle is still connected after charging completed. When the undervoltage alarm sets, the alarm
condition will persist for a minimum of one minute, after which time the alarm will clear when voltage
rises to 177 Vac or above.
Code 213 – Smart meter charge disable
This alarm is not applicable to NEMA WattStation Pedestal.
Code 214 – Open ground detected
This alarm indicates that the charge controller has detected a line side open ground condition. The
alarm condition will persist for a minimum of one minute, after which time the alarm condition will
clear if the ground continuity is restored.
Important!
Please note that WattStation Pedestal will not operate correctly on isolated, ungrounded power
sources. The ground monitor feature functions by introducing very small leakage currents from
line (L1) to ground, and then checks for the presence of those currents. On isolated, ungrounded
power sources, those leakage currents won’t flow reliably.
In such case, the ground monitor feature
can be disabled by applying a wire jumper at input J14A (contact GE Post Sale Service).
