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.
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.
Voltage for delta U detection ‘NiMH Sensitivity’/‘NiCd Sensitivity’ (NiMH and NiCd bat-
teries only)
Here, set the voltage at which the delta U charging method detects a fully charged battery. If
the value is too high, the charger may fail to recognise that the battery is fully charged. In that
case, the charging duration safety timer or the capacity limitation circuit will usually respond
(if set correctly). Voltages can be set between 3 mV and 15 mV. The default setting is 4 mV.
If the value is too low, the charger switches off before the battery is fully charged.
Change the voltage step-by-step and monitor the charging process. Due to the large
variety of different batteries, it is not possible to recommend an optimal setting.
Delay time for delta U detection ‘PEAK DELAY’ (NiMH only)
The charger ends the charging process for NiMH batteries using the delta U method. Here, set
how long the charger should continue charging after the delta U detection.
Switching button confirmation/warning tones on/off ‘Key Beep’
Use the ‘Key Beep’ function to enable (‘ON’) or disable (‘OFF’) button confirmation tones to
confirm operations and settings. Use the ‘Buzzer’ function to enable (‘ON’) or disable (‘OFF’)
function/warning messages.
Displaying the firmware version ‘Version’
The charger’s current firmware is shown at the bottom right of the LC display.
Loading factory settings ‘LOAD FACTORY SET’
This functions allows you to restore factory settings.
Press and hold the
ENTER START
button
(6)
for longer than 3 seconds. ‘COMPLETED’
appears on the LC display
(10)
. The charger then restarts and loads the main menu.
Note that all previously configured settings will be restored to the factory defaults.
The data in the 10 battery profile memories will also be deleted.
Additional process information
You can fetch information on the charging and/or discharging process during the charging
process or on the LC display.
• Press the
STATUS DEC -
button
(8)
to display the various settings on the LC display
(10)
.
If no button is pressed for a few seconds, the charger returns to the normal display.
• Press the
STATUS INC +
button
(7)
to display and monitor the voltage of individual cells
if you have connected a balancer cable for charging lithium batteries. Briefly press the
ENTER START
button
(6)
so that the charger returns to the normal display.
This display shows the final voltage applied to the battery at
the end of charging.
This display shows the internal temperature of the device and
the battery temperature (if an external temperature sensor is
connected).
This displays indicates whether the safety timer is on (‘ON’).
The duration of the set time is also displayed in minutes.
The display indicates that maximum capacity limitation is
switched on or off, plus shows the set maximum shut-off
value.
A balancer cable is connected to the battery. The charger can
verify the cell voltage of individual cells in the battery pack.
Warning and error messages on the LC display
The charger monitors its functions and displays warning messages. Warning tones are also
sounded.
REVERSE POLARITY
The polarity of the battery connections is incorrect.
CONNECTION BREAK
The connection to the battery has been interrupted, e.g. if the
battery was disconnected during charging.
CONNECT ERROR
CHECK MAIN PORT
The battery was connected with reverse polarity.
BALANCE CONNECT
ERROR
The balancer terminal on the battery was not connected
properly or was connected with reverse polarity.
INT.TEMP.TOO HI
The internal charger temperature is too high.
EXT.TEMP.TOO HI
The temperature measured by the external temperature
sensor (not included, available separately) is too high.
OVER CHARGE
CAPACITY LIMIT
The preset capacity limit (see section 16) was exceeded.
OVER TIME LIMIT
The preset time limit for the charging process was exceeded.
BATTERY WAS FULL
The connected battery is fully charged. If necessary, check
the setting for the number of cells.
Care and cleaning
Never use aggressive detergents, rubbing alcohol or other chemical solutions,
as these may damage the housing or stop the product from functioning properly.
• Disconnect the product from the mains before each cleaning. Disconnect the plug from the
mains power socket.
• Use a dry, lint-free cloth to clean the product.
• To prevent scratch marks, do not press too hard on the surface of the enclosure or LC
display when cleaning.
Disposal
a) Product
Electronic devices are recyclable waste and must not be placed in household waste.
At the end of its service life, dispose of the product according to the relevant statu-
tory regulations.
Remove any inserted (rechargeable) batteries and dispose of them separately from
the product.
b) (Rechargeable) batteries
As the end user, you are required by law (Battery Ordinance) to return all used
(rechargeable) batteries. Disposing of them in household waste is prohibited.
(Rechargeable) batteries containing hazardous substances are labeled with this
symbol to indicate that disposal in domestic waste is forbidden. The abbreviations
for the heavy metals involved are: Cd = Cadmium, Hg = Mercury, Pb = Lead (name
on (rechargeable) batteries, e.g. below the waste bin icon on the left).
Used (rechargeable) batteries can be returned to collection points in your municipal-
ity, our stores or wherever (rechargeable) batteries are sold.
You thus fulfil your statutory obligations and contribute to environmental protection.
