CHARGING

1. Connect the charger to the battery.

2. Connect the charger to the wall socket. The power lamp will indicate that the mains

cable is connected to the wall socket. The error lamp will indicate if the battery clamps

are incorrectly connected. The reverse polarity protection will ensure that the battery

or charger will not be damaged.

3. Press the MODE-button to select charging program.

4. Follow the indication lamps through the charging process.

The battery is ready to start the engine when is lit.

The battery is fully charged when is lit.

5. Stop charging at any time by disconnecting the mains cable from the wall socket.

CHARGING PROGRAMS

Settings are made by pressing the MODE-button. After about two seconds the charger

activates the selected program. The selected program will be restarted next time the

charger is connected.

The table explains the diﬀerent Charging Programs:

Program Battery

Size (Ah) Explanation Temp range

NORMAL 8–250Ah

Normal battery program

28,8V/4A. Use for WET batteries,

Ca/Ca, MF and for most GEL batteries

+5°C–+50°C

(41ºF–122ºF)

AGM

8–250Ah

AGM battery program 29,4V/4A

Use for AGM batteries.

-20°C–+5°C

(-4ºF–41ºF)

RECOND 8–250Ah

Recond program 31.4V/1.0A

Use to return energy to the empty

WET and Ca/Ca batteries. Recond

your battery once per year and after

deep dischare to maximise lifetime and

capacity. The Recond program adds the

Recond step to the normal battery

program. Frequent use of the Recond

program may cause water loss in the

batteries and reduce service life of

electronics. Contact your vehicle and

battery supplier for advice.

-20°C–+50°C

(-4ºF–122ºF)

ERROR LAMP

If the error lamp is lit, check the following:

1. Is the chargers positive lead connected to the

batterys positive pole?

2. Is the charger connected to a 24V battery?

3. The clamps are short circuited?

4. Has charging been interrupted in or ?

Restart the charger by pressing the MODE-button. If charging

is still being interrupted, the battery...

...is seriosly sulphated and may need to be replaced.

...can not accept charge and may need to be replaced.

...can not keep charge and may need to be replaced.

STEP 1 DESULPHATION

Detects sulphated batteries. Pulsing current and voltage, removes sulphate from the lead

plates of the battery restoring the battery capacity.

STEP 2 SOFT START

Tests if the battery can accept charge. This step prevents that charging proceeds with a

defect battery.

STEP 3 BULK

Charging with maximum current until approximately 80% battery capacity.

STEP 4 ABSORPTION

Charging with declining current to maximize up to 100% battery capacity.

STEP 5 ANALYSE

Tests if the battery can hold charge. Batteries that can not hold charge may need to be replaced.

STEP 6 RECOND

Choose the Recond program to add the Recond step to the charging process. During the Recond step

voltage increases to create controlled gasing in the battery. Gasing mixes the battery acid and gives

back energy to the battery.

STEP 7 FLOAT

Maintaining the battery voltage at maximum level by providing a constant voltage charge.

STEP 8 PULSE

Maintaining the battery at 95–100% capacity. The charger monitors the battery voltage and gives a

pulse when necessary to keep the battery fully charged.
