LED indicators

Status indications

A	B	C	D	E	F	G
H	I	J	K	L	M	N

Ref	Description	Meaning	Troubleshooting
A	White LEDs rolling from the bottom to the top	EVC 2 is booting up.	Normal behaviour – no action needed.
B	White LEDs rolling from the top to the bottom	EVC 2 is Reserved (OCPP only).	Normal behaviour – no action needed.
C	White pulsing LEDs	EVC 2 is in standby mode and waiting for action.	Normal behaviour – no action needed.
D	Yellow LEDs on	EVC 2 is not charging, simplified charging sequence is required.	Open installer menu via the app and select to allow simplified charging sequence.
E	Blue LEDs lights up from the middle	EVC 2 do not require permission, it is waiting for EV to initiate charging process (go to state C).	Normal behaviour – no action needed.
F	Blue LEDs pulsing	Permission to charge is not granted. EVC 2 requires authorisation.	Authorise yourself with app or NFC card.
G	Blue LEDs rolldown from up to down	Wait for scheduled time. No dynamic power – DLB/DLM/Solar enabled and no sufficient power. EVSE (charger) suspended. Reserved charge (OCPP only).	Go to settings via the app and select schedule time section to check for set graphs Wait for more available power or increase amperage limits via settings (if your grid allows it) Available power is less than 6 A. Provide more power or wait for more to generate. Other user has already reserved this charging station or RemoteStartTransaction command was received (OCPP only)
H	Four middle blue LEDs pulsing	EVC 2 waiting to add new NFC card.	Normal behaviour – no action needed.
I	Green LEDs pulsing	Initialisation of charging.	Normal behaviour – no action needed.
J	Green LEDs rolling upwards from the bottom	EVC 2 is in charging process.	Normal behaviour – no action needed.
K	Green LEDs on	EVC 2 finished charging.	Normal behaviour – no action needed.
L	Purple LEDs on	EVC 2 requires ventilation (charging is done in state D).	Open installer menu via the app and select that charging location is ventilated. To select that charger must be installed in ventilated location.
M	Red four middle LEDs	NFC/RFID card declined from the server.	Check if NFC/RFID card is in a server cards whitelist.
N	Green four middle LEDs	NFC/RFID card accepted from the server.	Normal behaviour – no action needed.

Red LED indications (errors)

A	B	C	D	E	F	G	H

Ref	Description	Meaning	Troubleshooting
A	First LED lit up in red	Input voltage error. Causes: Overvoltage Undervoltage Wrong wiring	Check if input wiring is connected correctly; Measure input voltage; Check installer menu settings if supply voltage and voltage tolerance is in accordance with the measured input voltage.
B	Second LED lit up in red	Output voltage/current error. Causes: Overvoltage Undervoltage Output current	Disconnect charging cable from the EV and check if the issue remains. Reboot charger and try to connect EV again.
C	Third LED lit up in red	Current leakage detected.	Disconnect the cable from the EV and check if the error persists. If the error is cleared, try to start charging. If the error occurs once again, try following steps: Check if charging cable is fully plugged into socket and/or EV; Check if the inside of both the socket and the plug has no foreign materials inside (is clean). Check visually if the cable is not damaged. Check if the boards are not covered in dust and/or other materials.
D	Fourth LED lit up in red	Connectivity error. Causes: Cable lock PP fail Car diode	Check if the charging cable is connected correctly from the charger side (socket version) and from the EV side; Try to reconnect charging cable to the EV and EVSE (charger) (if it is socket version). Listen if you can hear a clicking sound from the EVC 2 when you plug the cable to EV. Charger should lock cable plug. If you can’t hear, try to unplug cable (from EVSE (charger) side) while it is plugged from EV side. If it is possible to unplug, report this problem via VIP helpdesk or your sales manager. If none of these steps helps, measure the voltage between PE and PP and check if it is in accordance to the standard.
E	Fifth LED lit up in red	Temperature error. Causes: Temperature reached 85 °C	Check the temperature inside the app > Device info. If temperature is higher than 85 °C wait while charger cools down.
F	Sixth LED lit up in red	Internal errors. Causes: −12 V	Restart EVC 2
G	All LEDs pulsing red	Faulty connection to EV. Causes: CP fail	Try reconnect charging cable from the EV side. There might be control pilot communication problem which can occur with different EV models.
H	First LED lit up in orange	Warning. Problems with energy meter: Unrecognised Badly set Communication problems Other problems: Temperature Current D state	Go to the live data section and see what is the main problem. Check connected wires via EVC 2 and energy meter inputs; Check if the energy meter is compatible; Check temperature.

If the issue persists, report it via VIP Helpdesk or your sales manager. Please provide as much information as possible (photos, videos, etc.), as this helps solve it faster.

Warnings

Warning message	Meaning	Troubleshooting
Simple CP detected	Connected EV uses Simplified charging sequence. Charging power is limited to 1 Phase 10 A;	Connected EV uses Simplified charging sequence. Charging power is limited. In installer menu option „Simplified charging sequence“ must be turned ON.
Temperature warning	Temperature higher than warning limit, current throttling is present.	Charging will continue at a reduced rate.
Ventilation required	EV requiring ventilation	Check if Charging location is sufficiently ventilated.
RTC time lost	EVSE (charger) date and time lost	Check EVSE (charger) RTC coin battery (CR1220).
Simplified CP denied	Simplified CP detected and not allowed	Connected EV uses Simplified charging sequence. Simplified CP charging is disabled in Installer menu.
D state denied	EV requiring ventilation but charging location is not ventilated	EV requiring ventilation, but Charging location is specified as not ventilated in Installer menu.
Sensors not calibrated	Sensors were not calibrated during HW configuration	Contact support.
Energy meter comm error	Energy meter communication error	Check RS485 connection with external meter. Inspect cable. Check if meter is working. Make sure devices are configured properly.
NFC init error	NFC initialisation error	Reboot charger and check if the issue remains.
Low battery voltage	Low battery voltage EVSE (charger) (RTC)	Check EVSE (charger) RTC coin battery (CR1220).
Emeter wrong type	Energy meter configuration mismatch	Connected Energy meter and configured Energy meter type in Installer menu are different.
E-meter unidentified	Energy meter type unidentified	Unknown device detected. Check if the energy meter is compatible.
Main Board boot fail	Main board is failing to boot	Reboot charger and check if the issue remains - contact support.

These warning LEDs show that there is an active warning in the charger. This warning indication will work with other indications. If the issue persists, report it via VIP Helpdesk or your sales manager. Please provide as much information as possible (photos, videos, etc.), as this helps solve it faster.
