Gdc Current Leakage Detector; H - Welded Contactor Detector - Circontrol Wallbox eNext Series Installation Manual

Wallbox eNext Series Installation Manual
G
This protection is performed in two different ways depending on the Charge Point power supply.
• Single-phase power supply: The detector sends a signal to the Charge Point main PCB
which stops the charge transaction by opening the inner relays. This error is notified by 6
blinking red lights.
In order to restart the charge transaction, unplug the EV. When the beacon lights turn back
to green, it is possible to start another charge transaction.
• Three-phase power supply: The detector sends a signal to a trip coil that trips the electric
protections. Meanwhile, the Charge Point stops the charge transaction and notifies the
error by 6 blinking red lights.
In order to restart the charge transaction, unplug the EV.
When the EV is unplugged, the Charge Point shows 6 blinking red lights until the current
leak detector is automatically reset. After that, it shows 3 blinking red lights, meaning that
no voltage is detected in the power circuit.
In order to fully restore the Charge Point, rearm the electric protections. The beacon lights
turn back to green and it is possible to start another charge transaction.
If protections are installed outside the Charge Point, they shall include a trip coil and its signal
shall be connected to the Charge Point as shown in the next section.
H
This device detects if a contact is welded and protects the Charge Point.
This protection is performed by sending a signal to a trip coil that trips the electric protections
and the Charge Point stops the charge transaction. After that, the Charge Point shows 12 blinking
red lights. In order to solve this error, please contact with technical support.
If protections are placed inside the Charge Point, no
further actions are required to enable this feature.
If protections are installed
outside the Charge Point,
they shall include a trip
coil and its signal shall be
connected to the Charge
Point as shown besides.
