Indicator Lamps:
„Battery Full“
Battery (Batteries) fully charged
, green:
If it is lighting: Battery (batteries) has (have) been charged to 100 %, Float charge, conservation of charge U2,
finished.
If it is flashing: Main charging process is effected in the Absorb charge charging phase U1, indication of
charging state of approx. 80 % (short flashing), gradual increase to 100 % (long flashing).
Off:
Main charging process, Bulk charge, is still being executed in the phase I.
„Main Charging“
Main charging,
yellow:
If it is lighting: Main charging process is Bulk- or Absorb charge, in the phase I or the charging phase U1.
Off:
Float charge, conservation of charge U2.
If it is flashing: 1. Disconnection of the battery protection: battery “A” temperature < -40 ° C or temperature
rise (depending on type, e.g. 57 ° C or 63 ° C), automatic reset in case of slight cooling off
or
2. External battery overvoltage > 15.50 V (> 31.0 V) after 20 seconds
automatic reset < 12.75 V (< 25.5 V) after 30 seconds
„Current“
Charging Current,
red:
The lighting intensity of the LED „Current“ (Charging Current) will be
reduced or increased depending on the
supplied charging current
.
„Battery I“, yellow:
If it is lighting: Control and charging of main battery „I“.
Off:
Output is blocked (safety switch)
„Battery II“, yellow:
If it is lighting: Control and charging of auxiliary battery „II“.
Off:
Output is blocked (safety switch)
„Power “
Mains,
red:
If it is lighting: Mains supply is available and charger is ready for operation.
If it is flashing: 1. Disconnection of safety timer, duration of the charging phase I was too long, too many
consumers, battery defective (short-circuit of the cells). Reset is only possible by
withdrawing the mains plug.
2. Internal unit failure (overheating), automatic reset after cooling down.
3. Wrong polarization of battery (+ and - are mixed up).
Operating Instructions:
Interruption of the Charging Process:
In case of a power failure or withdrawal of the mains plug during the charging process, the charging process
will be interrupted. The connected batteries
will not be discharged
by the charger. Thus, the charging process
can be interrupted at any time.
In case of frequent interruptions, particularly before reaching the full charge (LED „Battery Full“ is lighting
permanently
), the battery should be subject to an
occasional full charging cycle of 24 hours
for equalisation
of the charge.
Lifetime of the battery: Partially Discharged Batteries:
In contrast to other battery types, batteries on lead basis
do not have any
harmful memory effect.
Consequently: In case of doubt, partially discharged batteries are to be
charged fully
as soon as possible.
Store only fully charged batteries
and recharge them periodically, particularly in case of used (older) batteries
and higher temperatures.
Lifetime of the battery: Recharge totally discharged batteries immediately:
Sulphation
of the battery plates due to total discharge is to be prevented by
immediate charging
, particularly
in case of low and high ambient temperatures. If the grade of sulphation is not too intensive, the battery can
recover part of the battery capacity after
several charging/discharging cycles
.
Lifetime of the battery:
Keep batteries cool; choose an appropriate location for installation.
Overvoltage Protection:
12 V chargers are protected against connection of excessive battery voltage rates or
will be switched-off in case of defective additional charging systems (solar systems, generators or similar
systems), switching threshold 15.5 V (31 V), delay 20 s.
Overvoltage Limitation:
Sensitive consumer loads are protected by means of a limitation of the charging voltage to max. 15 V (30 V)
during all modes of charging.
Overload / Overheating Protection Charger:
The charger is equipped with a double electronic protection against overload. The unit is equipped with an
automatic protection against adverse installation conditions (e. g. insufficient ventilation, excessive ambient
temperatures) by gradual reduction of the charging capacity.
Voltage Measurement:
Measurement of the voltage is to be effected at the battery and not at the charger (loss
at the charging cables).
