Set the voltage for Delta-U-recognition (for NiMH or NiCd only)
The charger uses the delta-U charging procedure for NiMH and NiCd re-
chargeable batteries to see if the rechargeable battery is fully charged.
Instead of the internal default settings, the voltage value can be specied
manually (in mV per cell).
If the value is set too high, the charger may not recognise that the rechargeable battery is fully charged.
The protection circuit for the charge duration or the maximum capacity usually trips here (if set correctly).
If the value is set too low, the charge will switch off too early and the rechargeable battery will not be fully
charged.
Change the voltage in steps and check the charging process. Due to the many different rechargeable bat-
teries, it is not possible to suggest a perfect value.
Switch the overtemperature protection on/off and set a temperature threshold
The charger offers a connection for a temperature sensor (not enclosed, can
be ordered separately).
If the overtemperature protection is on ("ON"), the charger will interrupt charg-
ing and discharging.
Set the desired temperature at which the charger is supposed to switch off.
If no temperature sensor is connected, switch off the overtemperature protection ("OFF").
Switch the safety timer on/off and set the duration
If charging 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 charge process is terminated auto-
matically after a set time if the safety timer is on. This protects the battery
from overloading.
The safety timer can be switched on ("ON") or off ("OFF"); the time for the safety timer can also be changed.
Do not set the time too short, since the rechargeable battery cannot be fully charged then because the
safety timer will cancel charging.
Some calculation examples for the duration:
Battery capacity Charging current Timer 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
The factor 11.9 is used to permit charging 140% of the rechargeable battery capacity (the rechargeable
battery is guaranteed to be fully charged then), before the safety timer trips.
