How the HMI works
The Human Machine Interface of the Wallbox eM4 Twin informs the user about the current status of the wallbox or
the two charge points. Visual feedback is provided by an LED ring with different colour and movement patterns. The
wallbox also emits sound signals for selected functions.
The following table shows the HMI signal and its corresponding functional status:
Boot process active
When the Wallbox eM4 Twin is connected to the elec-
tricity grid or restarted during setup, it starts the boot
process: The LEDs light up green, blue, white and red
for 5 seconds.
Configuration required
If the wallbox has not yet been set up via the
ABL Con-
figuration App
during first use or if the setup is cur-
rently being performed, the LED circle pulsates white.
Completing the configuration
Once the setup has been completed in the
ABL Config-
uration App
and transferred to the wallbox, the LEDs
light up white one after the other in a clockwise direc-
tion until finally the entire LED ring is lit up white con-
tinuously for a short moment.
Ready for charging
In normal operation, the status indicator pulsates green
to indicate readiness for charging. The right half of the
status indicator is assigned to the right-hand charge
point, the left half to the left-hand charge point.

Vehicle connected and recognised
If a vehicle has been connected and recognised, the
half that corresponds to the charge point lights up static
green.

Authorisation required
If the charging operation has to be enabled using an
RFID card, a blue chase light is shown dynamically on
the status indicator.
For the right-hand charge point, the chase light turns
anti-clockwise (see illustration).
For the left-hand charge point, the chase light turns
clockwise.
