9. Operation
9.1 Initial Setup
By default, this charger will be set to the user settings when first connecting an 11-18 V load. To alter the
parameters, press START/ENTER and change the value with INC/DEC. Store the value by pressing
START/ENTER once.
Starting screen
This screen displays the nominal voltage of the lithium battery. There are
three kinds of lithium batteries: Li-Fe (3.3 V), Li-Io (3.6 V) and Li-poly
(3.7 V). This is very important for the correct setup as a wrong value may
damage the battery during the charging process.
This charger automatically recognizes the battery type. However, a deeply
discharged battery can be perceived incorrectly. To prevent errors and
damage, please set the term time
– at about 10 minutes or even more for
larger batteries – so the charger will recognize the battery correctly. If in
doubt, leave the term time to the default setting.
Display of the trigger voltage for automatic charge termination of NiMH and
NiCd batteries. The effective value ranges from 5 to 20 mV per cell. If the
trigger voltage is set higher, there is a danger of overcharging the battery; if
it set lower, there is a possibility of premature termination. Please refer to
the battery’s specificat ions (NiCd default: 12 mV, NiMH default: 7 mV).
An optional feature is the temperature cut-off option using a temperature
probe contacting the surface of the battery. If this option is on, set the
maximum temperature at which the charger should allow the battery to
reach during charging. Once a battery reaches this temperature during
charging, the process will stop to protect the battery.
The battery warms after each charging/discharging cycle. The programme
will insert a time delay after each charging/discharging cycle to allow the
battery to cool down before beginning the next cycle. The valid value ranges
from 0 to 60 minutes.
When the charging process starts, the integrated safety timer starts running
simultaneously. If an error is detected or the termination circuit cannot
detect whether the battery is fully charged or not, the charger is
programmed to prevent overcharging.
