On the first page of the system menu, push the button "SAFETY OPTION", another setting menu appears.
"TIM.": 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-recognition), the charging will be terminated automatically after
the end of the time set here if the safety timer is on. This protects the battery from overloading. The safety timer can
be switched on ("ON") or off ("OFF") by pushing the button "TIM"; the time for the safety timer can also be changed
with the buttons "-" and "+".
Do not set the time too short, since the rechargeable battery cannot be fully charged then because the
safety timer will cancel charging prematurely.
Calculate the time for the safety timer as follows (examples):
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.
"CAP.": This safety function of the charger terminates charging automatically when a certain capacity has been "load-
ed" into the battery. The safety function can be switched on ("ON") or off ("OFF") by pushing the button "CAP"; the
capacity can also be changed with the buttons "-" and "+".
However, do not set a capacity which is too low; otherwise the rechargeable battery cannot be fully
charged.
"TEM. CUT": The charger can automatically cancel charging/discharging if the rechargeable battery exceeds the
temperature set here. Set the temperature with the button "+" or "-".
To use this function, an external temperature sensor is required (not enclosed, can be ordered as an ac-
cessory). It must be connected to the respective socket of the respective charge/discharge channel of the
charger.

"BACK": This button returns you to the previous setting menu.
