Installation of the Unit:
The charger can be installed
near Battery I
(short charging cables) at any location being clean and being protected
from humidity and dust. Despite the charger's high efficiency, heat is produced, which is brought out of the casing
by means of the built-in fan.
Ensure sufficient
ventilation
in the
environment of the unit,
so that the heat can be carried-off. Protect the unit
from aggressive battery gas.
The unit can be installed in any position. However, the
vent holes
of the casing should never be covered to ensure
the full charging capacity (
minimum distance:
10 cm
).
Ensure a solid and vibration reducing installation using
rubber bushings
on an even and hard mounting surface.
Battery Connection and Battery Settings for Start-up:
Observe the connection plan! Observe the cable cross-section and length, as well as the polarization, and insert the
fuses near the battery.
First connect the charger
(it is short circuit-proof), and after that the battery (it is not short circuit-proof).
1.
Connect 1 battery to the large terminals „ - “ und „ + “ observing the correct polarity.
2.
Set the
charging program
for the battery type (technology): See
Table
1.
Insert the mains plug (unit rear), and the automatic charging process starts.
Option:
Several Batteries at Main output Battery I:
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 of the batteries 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, type, capacity, as well as of the same age (history) in cross connection.
Option: Temperature Sensor
(Temperature Sensor, Order No. 2001 is required):
The temperature sensor controls
battery temperature I
and the temperature-dependent correction of the charging
voltage. It is connected to the unit terminals
„ T T “
(any polarity).
Installation:
The
thermal contact
of sensor and
battery I
(inside temperature)
should be well
. Thus, it should be screwed to the
negative pole of the battery. It is also possible to fasten it at the centre of the battery's casing sidewall. Ensure that
the installation place is not influenced by any source of heat (motor unit, exhaust, heater etc.).
Effect:
The temperature-dependent charging voltage of the battery will be adapted automatically to the battery
temperature (
also refer to
„Charging Voltage Rates of Battery I and Temperature Compensation“).
The temperature sensor measures the battery temperature. In case of low temperatures (winter operation), the
charging voltage will be increased in order to improve and accelerate the full charging of the weak battery. Sensitive
consumers are protected by a limitation of the voltage in case of very low outside temperatures.
In case of summery temperatures, the charging voltage is reduced to minimize the stress (gassing) of the battery and
to extend the lifetime of gas-tight batteries.
Battery Protection
(see Characteristic Lines "charging voltage and temperature compensation"):
At high temperatures of the battery (depending on type, for example 54 °C or 58 °C) the charging current will be
reduced to 50 % as a precaution. If the temperature of the battery rises still further, few ° C higher a complete
disconnection is issued by the safety switch.
LED "Main Charging" will be flashing.
All previous data of
charging will be recorded. The automatic charging will continued if the temperatures is fallen below the above
temperatures. The charging process is also blocked at battery temperatures
below – 40 °C.
The charger recognizes automatically a missing sensor, cable break or short-circuit of the sensor lines,
as well as unreasonable measuring values! In that case, it will switch to the usual nominal voltage rates
of 20 °C / 25 °C being recommended by the battery manufacturers.
