Operating Instructions:
Display of the residual charging time:
A flashing pilot lamp
"Battery Full"
allows conclusions concerning the progress of the charging phase U1 (full charging).
Directly after the charging phase I (approx. 75 % for lead, approx. 90 % for LiFePO4), the pilot lamp will only be flashing
momentarily. With progressing charging time, flashing will change more and more to permanent lighting, until the pilot
lamp will be lighting most of the time and will only stop lighting for a short moment, shortly before 100 % full charge is
reached.
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 full charge (LED "Battery Full" is lighting
permanently
),
the battery should be subject to an
occasional full charging cycle of 24 hours
for equalization of the charge.
Overvoltage Protection:
The unit protects itself 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, delay 20 s.
Automatic charging is resumed, if the battery voltage drops to nominal level.
Overvoltage Limitation:
Charging voltage limitation to max. 15.0 V during all charging modes to protect sensitive consumers.
Overload / Overheating Protection Charger:
The charger is equipped with a double electronic protection against overload and protects itself against adverse
installation conditions (e. g. insufficient ventilation, excessive ambient temperatures) by gradual reduction of the
charging capacity.
Lifetime of the battery: Partially discharged lead 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 or lower temperatures.
Voltage Measurement:
Measurement of the voltage is to be effected at the battery and never at the charger (loss at
the charging cable).
Option:
Several Batteries at Main Charging Port I (Master):
Parallel charging of two or several batteries of the same voltage (12 V) is admissible. The batteries are to be "paralleled",
i. e. the "+" connections have to be coupled and should be connected to the "+" connection of the charger. The minus (-)
connections have to be coupled in the same way.
The total capacity (total Ah) should not exceed the indicated maximum
battery capacity (depending on the case of application).
According to the battery manufacturers,
permanent
parallel operation is admissible in case of two or several batteries of
the same voltage, same type, same capacity, and of about the same age (history) in cross connection.
