voltage
After connection to the grid, the appliance is on
STANDBY. The standby display

lights up. When
the clamps are connected, the battery voltage is
shown in the LCD (voltage display
9
). The segments
of the condition display

are empty.
If the voltage is below 3.8 V or above
15 V, the battery will not be charged. The
display briefly shows the error message
„Err“. The appliance goes on standby.

6 V battery
If the voltage range of the battery is measured as
between 3.7–7.3 V, only programme 1 can be se-
lected.
12 V batteries:
If a battery is recognised in the critical voltage
range of between 7.3–10.5 V, the appliance checks
whether a fully charged 6 V battery, or a discharged
12 V battery is present. After pressing the programme
selection button
10
to select a programme, the ap-
pliance carries out a control measurement for about
90 sec.
The display shows:

If after about 90 sec. between 7.3–7.5 V are detected,
the 12 V battery is defective.
The appliance goes on standby.
Revitalising
If after about 90 sec. between 7.5–10.5 V are de-
tected, a 12 V battery is present.
Charging starts with a pulse charge for revitalising.
The voltage display

flashes. Once 10.5 V are
reached, the appliance switches to the other charge
steps.
Revitalising is the same for all the 12 V charge pro-
grammes.
Programme selection
NOTES:
If a battery is detected in the voltage range of be-
tween 3.7–7.3 V, the programmes 2–3–4 can be
selected.
The charging process takes place automatically.
Depending on the selected programme, the char-
acteristic charge curve is monitored for voltage,
time and temperature. Included are the diagnostics
programme, revitalising mode and retention charge.
