Last verified

First safe check

Check the app for the meter status and note whether the installation uses a MID meter at all.

What does Orange halo (blinking) mean?

A blinking orange halo indicates that communication between the charger and the connected MID-certified meter has failed. The charger cannot obtain the measured values it needs, so charging is not recommended until the link is restored.

Which models use this code?

Verified for

  • Wallbox — Pulsar Plus

Most likely causes

01

MID meter wiring or termination problem

Manufacturer documented

The data connection to the meter is open or incorrect.

02

Meter configuration mismatch

Possible

The meter settings in the configuration do not match the installed hardware.

Safe checks you can perform

  1. 1

    Note the app status

    Record what the app shows for the meter so an installer can act on it.

  2. 2

    Do not open the meter or charger

    Meter wiring sits on the supply side and must only be worked on by a qualified electrician.

These steps stay outside the enclosure. Never open high-voltage equipment, bypass safety devices or work on live wiring.

When to stop troubleshooting

Stop and contact a qualified technician if the fault returns immediately, the device smells burnt, visible wiring damage exists, the enclosure is hot to the touch, or the manufacturer specifies professional service.

Can a reset clear this fault?

Reset behaviour is not documented for this code. Use only the manufacturer-approved restart sequence described in the device manual, and treat a code that returns immediately as an unresolved fault rather than a reset problem.
