Should the connection of the clamps be swapped, the LED “reverse connection” lights up 5.
Disconnect
Disconnect the appliance from the mains supply.
Remove the “-” pole clamp (black) 15 from the “-” pole of the battery.
Remove the “+” pole clamp (red) 14 from the “+” pole of the battery.
Measuring Standby/Battery Voltage
After connection to the grid, the appliance is on Standby. The standby display 6 lights up. When the clamps are
connected, the battery voltage is shown in the LCD.The segments of the condition display 8 are empty. If the voltage
is below 3.8V or above 15V, the battery will not be charged. The display briefly shows the error message “Err”. The
appliance goes on standby.
6V battery:
If the voltage range of the battery is measured asbetween 3.7-7.3V, only programme1 can be
selected.
12V batteries:
If a battery is recognized in the critical voltage range of between 7.3-10.5V, the appliance checks
whether a fully charged 6V battery, or a discharged 12V battery is present. After pressing the programme selection
button 10 to select a programme, the appliance carries out a control measurement for about 90 sec.
The display shows:
If after about 90 sec. between 7.3-7.5V are detected, the 12V battery is defective. The appliance goes on standby.
Revitalizing
If after about 90 sec. voltage between 7.5-10.5V is detected a 12V battery is present. Charging starts with a pulse
charge for revitalizing. The voltage display 9 flashes. Once 10.5V are reached, the charger switches to the other charge
steps. Revitalizing is the same for all the 12V charge program
Program selection
NOTES
: If a battery is detected in the voltage range of between 3.7-7.3V, theprogramm 2-3-4 can not be selected. The
charging process takes place automatically. Depending on the selected program, the characteristic charge curve is
monitored for voltage, time and temperature. Included are the diagnostics program, revitalizing mode and retention
charge. (See principle representation program 3 Fig. C)

Program 1 “6V” (7.3V/0.8A)
For charging 6V batteries with a capacity of less than 14Ah.
Press the program selection button 10, to select program 1. The symbol “6V” is displayed on the LCD. During charging,
the charge display 7 flashes and shows the progress of the charge procedure (1-4 bars). When the battery is fully
charged, the condition display 8 shows 4 bars. The flashing stops and the charger automatically switches to float
charge.
Program 2 “12V” (14.4V/0.8A)
For charging 12V batteries with a capacity of less than 14Ah.
Press the program selection button 10, to select program 2. The symbol
is displayed on the LCD. During charging,
the charge display 7 flashes and shows the progress of the charge procedure (1-4 bars). When the battery is fully
charged, the condition display 8 shows 4 bars. The flashing stops and the charger automatically switches to float
