Safety notes are marked with this symbol in the main instructions. Please
read these notes carefully before work begins!
Adjustment work at the system must only be done by skilled electricians.
General Information
When central battery systems are supplied without battery or the type of battery
is unknown the tripple charge-voltage is set up with the factory default of 245V
(means 2.27V/Z).
According to the type of battery the tripple charge-voltage must be fitted at face.
Adjust the tripple charge-voltage as follows:
1. Press and hold the service pin (1) of the BCM for several seconds until the
green LEDs flash alternately. The control unit display is now controlled by
the BCM.
Make sure that no charge fault exists beforehand as otherwise the
ST 20 E activates an error display.
2. The voltage „U=“ (2), now shown in the display of the ST 20 E control
unit, is the float charge voltage to be set. The current displayed, „I=+“ (3),
represents the number of located CMs on the CCB bus, 1A = 1CM.
3. Now set the float charge voltage with the „ISO Test+“ and „ISO Test-“
buttons (4) according to battery manufacturer specifications.
Caution!
The float charge voltage is always set to the corresponding value at a tempe-
rature of 20° C.
4. To save the voltage, press and hold the service button (1) again until the
green LEDs stop flashing. Setting mode is terminated automatically after
one minute if the Iso Test buttons are no longer pressed.
