Regeneration mode (16 V BOOST)

Note: This mode is only suitable for 12 V batteries.

Note: In this mode, the batteries have to be charged

fully!

Suitable for the regeneration of completely flat

batteries with a capacity of more than 14 Ah in normal

conditions.

The LED for the regeneration mode U lights

up. As soon as the integrated switch is thrown,

the LED for the regeneration mode U flashes.

The process starts with an amperage of 16.5 A

(±0.25 V) / 1.5 A (±10 %).

Note: If the battery is nearly completely flat, the

LED for the regeneration mode U could flash for

up to 3 hours. During this time, constant amper-

age of 1500 mA will flow into the battery in order

to restore the battery's capacity. After a maximum

of 4 hours, the regeneration mode switches itself

off. If the battery has still not been fully charged,

the charger will switch to normal charging mode

(mode 1 - 4).

Impulse charging

As soon as the charger starts the charging process,

it automatically recognises the battery voltage. It

changes over to impulse charging when the battery

voltage is in the area of 4.5 V / 14 V to 10.5 V / 21 V.

This impulse charging continues until the battery

voltage rises to more than 10.5 V / 21 V; after that

the charger changes back to the charging mode

selected before. This process is able to regenerate

most flat, used or overcharged batteries so that

they can be re-used.

Charger protection function

As soon as an abnormal situation such as a short-

circuit, regeneration process of more than 7 hours,

charging process of more than 41 hours, battery

voltage less than 4.5 V (with 12-V batteries) or 16 V

(with 24-V batteries), open electric circuit or reversed

polarity occurs, the charger switches over to STANDBY

Operation / Maintenance

mode. If you do not input any other setting, the system

will remain on STANDBY. With reversed polarity, the

LED

"Error" Q will light up. This way, the sparks

that often arise during the connection process are

avoided.

Overheating protection

If the appliance becomes too hot during charging,

the power output is automatically reduced. This

protects the appliance from damage.

Memory function

Note: The memory function is not active in mainte-

nance and regeneration mode.

The charger has a memory function. As soon as the

charger has been connected to the mains supply, it

automatically switches to the mode of operation last

used. Due to the variety of different batteries and

conditions, we recommend you check the mode of

operation carefully and make any manual adjustments

if necessary (See "Selecting mode of operation").
