MANUAL DO UTILIZADOR

•

Do not modify the chargers, and in particular their safety systems.

•

Check regularly all internal electrical connections. Make sure that cables and terminals have not been damaged by

overheating due to bad contacts ; remove dust (in particular from contactor and moving parts).

•

Before cleaning the charger, disconnect it from mains and battery.

•

Battery chargers do not need any special maintenance, apart from the usual cleaning which has to be performed

regularly depending on the installation site.

•

The unit must not be used by unskilled or unqualified personnel, children or people with reduced physical and mental

abilities.

B) CONNECTION TO MAINS

The charger three-phase is pre-set for a three-phase mains supply of 400V AC. Should the charger be set for a three-

phase mains supply of 230V AC, perform voltage adjustments on the terminal board, retap taps on the auxiliary

transformer, and install the suitable mains fuses. The single-phase version is preset for operating at 230V AC.

In case of connection to a power supply protected by Automatic Circuit Breaker, use only SWITCHES with D or K curve

Make sure to earth the charger properly.

C) ADJUSTMENT TO MAINS VOLTAGE

Check mains voltage and adjust it, if required, by means of the adjusting terminal board on the transformer.

D) CONNECTION TO BATTERY

We advise the use of bipolar standard connectors which do not allow reverse polarity on battery.

Check cable connection in the connector contacts.

E) E) DESCRIPTION OF A CYCLE OF CHARGE

Since the charger is equipped with autostart, the charging process will automatically start a few seconds after

connection (provided that the charger has detected mains presence).

The charging process stops automatically when the battery has been fully charged.

The charging process begins only if battery voltage falls within the range foreseen for that charger.

If charging time exceeds the security timer (7 hours for a WOWa charger and 11h for a Pulse charger) before reaching

gassing voltage, the charging process is automatically interrupted by a safety timer.

Another safety timer will interrupt the charging process if the overall charging time exceeds 15 hours.

If a power failure takes place during the charging process, all data concerning the current charging process are

stored. On power-fail restart the charging process is resumed from the point reached before interruption.

EQUALIZING CHARGE

If battery charger remains connected to battery when the charge is over, an automatic equalizing charge will begin

after 16 hours. The battery charger calculates battery capacity making use of the average capacity calculated in the

last 7 charging cycles duly completed.

During the equalizing charge the green LED will blink.

If battery remains connected to charger for a long time, a floating cycle will be performed every 7 days in the same

way as equalizing is performed.

F) F) LED's and DISPLAY INDICATIONS

All significant charging data are displayed on a backlit display: Cell Voltage, Charging Current, Restored Capacity (Ah),

Charging Time and Failure Messages, if any.

In addition three LED's indicate the charge state.
