Operation / Maintenance
q
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).
q
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.
q
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
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.
q
Overheating protection
If the appliance becomes too hot during charging,
the power output is automatically reduced. This
protects the appliance from damage.
q
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”).
