AMBER indicates that the vehicle is charging. While charging, the VFD will display the amount of
charging time elapsed and total energy drawn.
Disconnect from Vehicle:
The EVSE can be disconnected from the vehicle at any time.
• Press and hold the button on top of the EVSE handle and pull the EVSE handle away from the
vehicle inlet socket. The VFD will prompt to replace the handle to the EVSE holder.
• Replace the EVSE handle on the holder by pressing and holding the button the EVSE handle.
Release the button when the EVSE handle is fully connected to the EVSE holder.
• The EVSE status indicator will return to SOLID GREEN once the EVSE handle has been removed
from the vehicle inlet and replaced to EVSE holder.
Faults:
When the status indicator has turned RED, the EVSE is indicating a fault. There are four types of faults
that can occur:
1. Ground Fault
2. Contactor closed when not charging Fault
3. Self-Test Fault
4. Overvoltage/Undervoltage Faults
5. Overload fault
Ground fault:
The EVSE can detect the presence of ground faults with a threshold of 15 – 20 mA during the charging
cycle. Once a ground fault is detected, the EVSE will stop charging the vehicle and the status indicator
will indicate RED. If the EVSE continues to detect ground faults and the vehicle remains plugged in,
the EVSE will attempt to restart charging after 15 minutes. If 4 such attempts to restart charging have
occurred, the EVSE will lockout the station. The lockout will prevent any vehicle from being charged
until the plug has been disconnected from the vehicle. It is highly recommended that service
personnel examine the EV (electric vehicle) and/or the EVSE cable to determine the cause of the
multiple faults before re-energizing.
If a ground fault is present immediately after the EVSE begins charging, the EVSE will stop charging
and immediately lockout the station. The lockout will prevent any vehicle from being charged until
the plug has been disconnected from the vehicle.
Contactor closed when not charging Fault:
The EVSE internally monitors itself to ensure that the EVSE is only supplying power to the EVSE handle
when it is in a charging cycle. If the EVSE is supplying power to the EVSE handle in a non-charge cycle
(status indicator is GREEN or FLASHING GREEN), the EVSE will lockout and the status indicator will
indicate RED. The lockout will prevent any vehicle from being charged until power has been cycled on
the EVSE.
Self-Test Fault:
