Battery voltage
This setting allows you to set the battery voltage for the selected battery type.
It is not possible to set just any voltage; the increment size depends on the rated
voltage of an individual cell of the respective battery type. For example, if the rated
voltage of a cell in a LiPo battery is 3.7 V, the voltage can only be adjusted in incre-
ments of 3.7 V (3.7 V, 7.4 V, 11.1 V etc.).
Charging current
Here, set the desired charging current. This must be selected according to the battery used.
The actual charging current flowing during the charging process depends on the
battery type and the number of cells. The max. charging power is 60 W.
Discharging current
Here, set the desired discharging current. This must be selected according to the battery used.
The actual discharging current flowing during the discharging process depends on
the battery type and the number of cells. The maximum discharging power is 10 W.
Discharge voltage per cell at the end of the discharging cycle
Here, you can set the voltage per cell at which the discharging process is ended.
Warning!
Never set the voltage too low. In the case of lithium batteries, this can lead to deep
discharge and permanent damage to the battery. Always note the battery manufac-
turer’s instructions.
Charging end voltage per cell
Here, you can set the voltage per cell at which the charging process for lithium batteries is
ended.
Warning!
Never set the voltage too high. In the case of lithium batteries, the battery may catch
fire or explode. Always note the battery manufacturer’s instructions.
Trickle charging current ‘TRICKLE’ (NiMH and NiCd batteries only)
Set the trickle charging current here. If a NiMH or NiCd battery is fully charged, it loses part of
its capacity again through self-discharge.
The trickle charging current (short charging pulses rather than a continuous charging current)
ensures that the battery remains fully charged. This also prevents crystal formation in the
battery.
The trickle charging current can be set between 5 and 300 mA. The preset is 100 mA.
Delay time for delta U detection ‘PEAK DELAY’ (NiMH and NiCd batteries only)
The charger ends the charging cycle for NiMH and NiCd batteries using the delta U method.
Here, set how long the charger should continue charging after the delta U detection. You can
switch this function on or off or set a recharging time in a range of 1 to 5 minutes.
Saving settings
To save the set values, select the ‘SAVE PROGRAM’ setting function, then briefly press the
ENTER START
button
(6)
. Otherwise, all settings will be lost.
The charger displays a message (‘SAVE...’) and beeps to indicate that the settings have been
saved.
Programme memory, loading battery data ‘BATT MEMORY’
• In the charger’s main menu, use the
STATUS INC +
and
ST
A
TUS DEC -
buttons
(7)
and
(8)
to select the ‘BATT MEMORY’ function.
•
Confirm the selection with the
ENTER START
button
(6)
. The memory number flashes
on the display.
• Use the
STATUS INC +
and
ST
A
TUS DEC -
buttons to select one of the 10 memories. If
the memory already contains data, the bottom row of the display shows the battery type and
number of cells as well the charging and discharging current in succession. If the memory
slot is empty, ‘ENTER SET’ is displayed in the bottom row.
• Load the battery data from the selected memory by holding down the
ENTER START
button for more than 3 seconds. The message ‘ENTER CHARGE LOAD.....’ appears on
the LC display, the data are then loaded and the desired charging/discharging programme
can be started
• Press and hold the
ENTER START
button
(6)
for more than 3 seconds to start the
programme.
If you press and hold the
ENTER START
button
(6)
for more than 3 seconds when
the memory is empty, the charger starts selection/setting mode in which you can set
and save battery programmes.
LiPo battery measurement function ‘BATT METER’
The charger can display the current voltages of the cells in a lithium battery. With the LiPo
battery measurement function, you can display the highest voltage, the lowest voltage and the
voltage of each cell.
Make sure to connect the balancer connectors to use the function.
To activate the display, proceed as follows:
In the charger’s main menu, use the
STATUS INC +
and
STATUS DEC -
buttons
(7)
and
(8)
to select the battery
measurement function ‘BATT METER’.
Confirm the selection with the
ENTER START
button
(6)
. The voltage is then displayed.
The LC display
(10)
displays the following values.
- Individual voltages of the cells 1 - 4
- Total voltage (‘MAIN’), maximum cell voltage (‘H’) and
minimum cell voltage (‘L’).
System settings
The system settings of the charger summarise various basic settings. In the as-delivered
condition, these are preset with the most common values. You may need to change the values
depending on the battery that you wish to charge/discharge. The following setting functions are
displayed on the LC display
(10)
in sequence. Individual parameter values can be modified as
required. Proceed as follows:
Select the system setting
‘SYSTEM SET’
in the main
menu.
Press the
STATUS INC +
and
STATUSDEC -
buttons
(7)
and
(8)
to switch between the setting variables.
If you want to modify a setting, press the
ENTER START
button
(6)
. The setting is activated. The activated
setting flashes.
Press the
STATUS INC +
and
STATUS DEC - (7)
and
(8)
buttons to modify the current setting.
Press the
ENTER START
button
(6)
to save a modified
setting.
Repeat this procedure for all adjustable setting variables
in the menu.
The setting variables are as follows:
Safety timer
To prevent a faulty battery from being overcharged, you can set a max. charging time (safety
duration) which must not be exceeded during charging. As soon as a charging process starts,
the internal safety timer starts as well. If the charger cannot detect whether the battery is fully
charged for whatever reason (e.g. with delta U detection), the charging process is terminated
automatically after a set time if the safety timer is activated. This protects the battery from
overcharging.
The safety timer can be switched on or off. You can also modify the duration of the safety timer.
Do not select a time that is too short, otherwise the battery will not charge fully
before the time has elapsed.
Determining the safety duration for NiMH and NiCd batteries
Calculate the time for the safety timer as in the following examples:
Divide the battery capacity value by the charging current and then by a factor of 11.9.
battery capacity / charging current / 11.9
Factor 11.9 is used to ensure that the battery can be charged to 140% capacity
before the preset time elapses (i.e. guarantee that the battery will be fully charged).
Examples
Battery capacity
Charging current
Safety time
2000 mAh
2.0 A
2000/2.0=1000)/11.9 = 84 minutes
3300 mAh
3.0 A
3300/3.0=1100)/11.9 = 92 minutes
1000 mAh
1.2 A
1000/1.2=833)/11.9 = 70 minutes
Capacity limitation with automatic shut-off at maximum charging capacity ‘Capacity
Cut-Off’
This safety function determines the maximum capacity to which the charger should charge
the battery. The charging process is automatically ended when a certain battery capacity is
reached. If the deltapack voltage is not detected or the time set on the safety timer has elapsed,
this function stops the charging process as soon as the set capacity value is reached.
This safety function can be switched on or off. You can also configure the capacity.
Do not select a capacity that is too low, otherwise the battery will not be fully charged.
Shut-off in case of excess temperature ‘Temp Cut-Off’
Here, set the temperature at which charging is interrupted by the charger. You can set shut-off
temperatures in a range of 50°C to 122°C.
Setting the temperature unit ‘Temperature Unit’
Here, set the desired temperature unit for the temperature value display. Celsius and Fahrenheit
are available for selection.
