CONTROL LAMPS & ERROR DEXCRIPTIONS
The control lamps on the top of the charger indicate different operating and error statuses:
Orange LEDs indicate the selected charger function
Green LEDs indicate that the battery has finished charging
The red LED indicates an error

CHARGING PROCESS

Batteries are charged fully automatically, monitored by a micro-processor with a three-stage IU1oU2 charge
characteristic for optimum and gentle treatment of the batteries. After connecting the battery to the PWC, the
charging parameters for the battery can be adjusted by selecting the type of battery (standard or gel/AGM).
Charging with constant current (I-phase, orange LED lights up)
The maximum charging current is used to charge the battery, depending on its charged status, so as to store as much energy as
quickly as possible in the battery. If a battery that has been totally discharged is attached to the charger, the charger will start
charging with reduced energy to avoid damaging the battery. Once the main charging voltage has been reached (14.4 (28.8) to
14.7 (29.4) V, depending on the type of battery) the charger switches to the next charging phase.
Charging with constant voltage (U1-phase, orange LED lights up)
The battery becomes fully charged in this phase. Voltage is maintained at 14.4 (28.8) V (when set to gel/AGM) or 14.7 (29.4) V
(when set to standard). As the charge increases, the current continuously decreases and approaches a lower limit that depends
on the type and size of the battery. As soon as it drops below this value or exceeds the set minimum charging period the charger
switches to phase 3.
Maintenance charging with reduced voltage (U2-phase, green LED lights up)
The charging voltage is reduced to 13.6 (27.2) V (when set to gel/AGM) or 13.8 (25.6) V (when set to standard) in
order to maintain the charge for an unlimited period of time, whereby the physically induced self-discharge is
compensated and the battery is maintained in a fully charged state until it is disconnected.
