NiCd / NiMH charge termination delay
At the start of the charge process the unit initiates a delay time

which suppresses automatic charge termination during this

(delay) period. This means: during this delay period the charge
voltage is not monitored, and the battery is charged for at
+
-
least the set length of time! The charge termination delay is

only effective n the NiCd and NiMH charge programs.
Warning: if you connect an already fully charged battery with the purpose of topping it up, it will be
charged for at least the delay time you have selected, and could then get very hot.
Caution - explosion hazard!
NiCd / NiMH safety timer

designed to prevent catastrophic overcharging of the battery
on charge if the pack proves to be faulty, or if the "battery full"

detection circuit malfunctions. The value you set for the safety
INC
DEC
timer must be generous enough to allow a full charge of the
battery. As a practical guide we recommend a time which is about 30% longer than the expected charge
period; naturally, this varies according to the charge current you have set. Example: 1.8 Ah battery,
charge current 3.6 A -> charge time = 1.8 Ah / 3.6 A - 0.5 hours = 30 min +30% = safety timer = 40 min.

The maximum charge current can be set using the INC /

The charge process is terminated according to the values
set by the user for „NiCd Delta-Peak Termination Voltage",
„Charge Termination Delay" and „Safety Timer".

This is particularly useful if you always
use the same charge current, as it avoids
the necessity to select the value sepa-

rately each time you use the charger.
In any case we recommend that you set
a "starting point" value of 2.5 A, as this
avoids the need to run through the enti-
re range every time you start using the
charger.
Car battery low voltage cut-off
If the charger is connected to a car battery which is not

it is safe to discharge it to a lower level.
The charger allows you to set an alternative value of 10.5 V,
which enables you to exploit the maximum capacity of the car

battery without deep-discharging it excessively.

The unit does not store the alternative setting, so you must

reset it (if required) every time you start using the charger.
Button click / buzzer settings
The purpose of this sub-menu is to adjust the settings for the audible sounder.
Button click:
Every time you press a button you will hear a "click" sound to confirm your action. This
sound can be switched on (EIN) or off (AUS).
Buzzer:
When the screen displays a warning, "completed" or an error message etc., the inte-
gral buzzer sounds at the same time to alert you. In this program point you can select
buzzer off (AUS), or the length (10 sec. or no time limt) of the audible warning.
