..3. Operation
7. Switch the battery charger on. After this
the red LED must light continuously (Fig. 2,
Pos. 2).
8. Use the potentiometer to set the battery
charging current to the required value.
!
When setting the battery charging current
make sure that the manufacturer's speci-
fications are adhered to.
9. Monitor the charging current on the display
(Fig. 2, Pos. 1). When in operation the yel-
low LED lights up (Fig. 2, Pos. 4).
i
If the green LED (Fig. 2, Pos. 3) lights up,
the battery voltage is 2.3 V per cell or 2.4
V per cell (depending upon the battery
temperature setting). If the battery is in
perfect working order this means that the
battery is charged to approx. 60 % and is
ready for starting.
!
Batteries have to be tested before per-
forming any trickle charge process. Only
fully intact batteries should continue to be
charged or trickle charged. Set the battery
temperature two-way switch to „hot batte-
ry" for battery continuous charge, trickle
charge or floating-mode operation.
10. The battery is fully charged, when the green
LED lights and when the battery charging
current display indicates that only a small
charging current is being registered. When
the charging process is over switch off the
battery charger.
11. Disconnect the crocodile clips from the
battery (remove the blue negative one
first).

3.4 Charging exhaustive discharge batteries
In this operating mode, you can charge:

very cold batteries

12 V batteries that have an open-circuit
voltage between 1 V and 8 V

24 V batteries that have an open-circuit vol-
tage between 2 V and 16 V, in other words
exhaustive discharge batteries
!
In each case only one exhaustive discharge
battery may be charged. Switch off all consu-
mers in the vehicle when charging exhaustive
discharge batteries.
1. Switch the battery charger off (Fig. 1,
Pos. 9).
2. Unscrew the cell plugs on standard batte-
ries before starting the charging process.
3. Connect the crocodile clip-on terminals
to the proper battery terminals (Fig. 1,
Pos. 1). The red-colored clip goes to the
positive terminal (+) and the blue one to
the negative terminal (-).
4. Set the two-way switch for „cold and hot
batteries" to the correct position (Fig. 2,
Pos. 6). Note that only the battery tempe-
rature is to be evaluated.
5. Turn the potentiometer for setting the
battery charging current (Fig. 2, Pos. 8)
to the left-hand maximum limit (lowest
charging current).
6. Set the two-way switch (Fig. 2, Pos. 5) to
the specified battery nominal voltage for
the battery to be charged.
