Sul mio, che è apparentemente uguale, quando carica il rosso 0 è acceso fisso.

Comunque, poiché mi fido poco della AI cercando si trova:

**The unit has the following displays**

LED Power- on

The device is connected to the mains

LED 0 - on

The battery is connected up, the device is in the main charging mode.

LED 0 - flashes:

Unit is de-sulphating mode with de-sulphating loops. If de-sulphating succeeds and current flow is enforced through the battery, the main charge mode continues. If de-sulphating fails, the charge is interrupted and "error" appears.

LED 1/3 - on

Device in main charging mode. Charging current has fallen to 1/3 of the initial value.

LED 2/3 - on

Device in main charging mode. Charging current has fallen to 2/3 of the initial value.

LED 3/3 - on

Battery fully charged. Maintenance charging now takes place. The unit can remain connected up. The battery is maintained by so-called "driving simulation cycles".

LED Error - on

Short-circuit at the charging terminals, battery connected to the wrong poles.

LED Error - flashes

Battery error, charge interrupted. The unit haas recongnised a wrong battery, e.g. 6V or 24V battery, battery is sulphated and revival failed or cell short-circuit.
