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 au-
tomatically 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 (10 to
720 minutes).
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 bat-
tery is guaranteed to be fully charged then), before the safety timer trips.
Automatic deactivation if the input voltage is too low
If the charger is operated at a car battery, this safety function prevents a
deep discharge of the car battery.
Set the voltage (10.0 V to 15.0 V) where the charger is to interrupt charging.
Switching the key confirmation sounds/warning sounds on/off
With the option "Key beep", confirmation beep for each push of a button is
switched on ("ON") or off ("OFF").
The function "Buzzer" switches the signal sound for various functions/warn-
ing messages on ("ON") or off ("OFF").
Switch the dimming function for the backlighting on/off
You can set a duration here (1 to 10 minutes), after which the display bright-
ness will reduce if no button is pushed.
At setting "Always OFF", the display brightness will not be reduced.
