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 bat-
tery is guaranteed to be fully charged then), before the safety timer trips.
Automatic deactivation at specic charging capacity
This safety function of the charger terminates charging automatically when a certain capacity has been "loaded" into
the battery.
The safety function can be switched on ("ON") or off ("OFF") and the capacity can be set.
However, do not set a capacity which is too low; otherwise the rechargeable battery cannot be fully charged.
Switching the key conrmation/warning sounds on/off
With the option "Key Beep", conrmation beep for each push of a button is switched on ("ON") or off ("OFF").
The function "Buzzer" switches the signal sound for various functions/warning messages on ("ON") or off ("OFF").
Monitoring of the input voltage
This function monitors the voltage at the charger input. This is sensible when a 12 V car lead battery is used for
power supply.
If the voltage drops below the set value, charging is terminated to prevent deep discharge of the car lead battery.
