System Settings - VOLTCRAFT 2267184 Bedienungsanleitung

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 STATUS DEC - buttons (7) and
(8) to select the 'BATT MEMORY' function.
• Confirm the selection with the ENTER START
on the display.
• Use the STATUS INC + and STATUS 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
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
(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:
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
2000 mAh 2.0 A
3300 mAh 3.0 A
1000 mAh 1.2 A
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.
Displaying the battery and charger temperature 'Ext. Int. Temp'
This functions displays the external battery temperature and the internal charger temperature.
The external temperature can only be displayed if an external temperature sensor is
connected to the charger (not included, available as an accessory). This tempera-
ture sensor is attached to the battery.
button
Pause length between charging/discharging 'Rest Time'
A battery heats up during charging (depending on the charging current). In charging/
discharging cyclical operation, the charger can pause between charging and discharging to
allow the battery to cool down before the next discharging process. Enter the length of the
pause between charging and discharging to give the battery sufficient time to cool down before
the next process is started. You can set pause lengths of between 1 and 60 minutes.
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.
Safety time
2000/2.0=1000)/11.9 = 84 minutes
3300/3.0=1100)/11.9 = 92 minutes
1000/1.2=833)/11.9 = 70 minutes
