Adjusting the charger float voltage
1.
The power supply must be at its nominal operating temperature. This normally requires the power
supply to be on for at least two hours with rated load and the housing fitted.
2.
Connect the charged battery. A battery that is not fully charged causes an error in setting the
charger voltage!
3.
Adjust the voltage at the battery terminals, if required, using the PO4 potentiometer referring to the
table below.
Warning! Destruction of device possible!
Ensure that only the PO4 potentiometer is adjusted...
1.
After having measured the temperature
2.
If the battery voltage deviates by >200mV from the nominal value, then adjust PO4 accordingly.
External NTC resistor (Art. No. 010693)
When using an
external NTC resistor
, NTC1, mounted on the printed circuit board, must be
removed
(pulled out).
The external NTC must be attached to the battery in an appropriate manner (e.g. with double-sided
adhesive tape).
Solder its leads to the pins of ST4.
Note:
An external NTC resistor is recommenced.
If the battery is located in a separate enclosure, then an external NTC resistor must be used.
