5.8.2 Funktion of the VCS
The output current of the generator is measured via a shunt with an output voltage of 60mV for
the rated current.
Factors concerning current measurement:
• The generator will shutdown if a cable break in the measurement wire from the shunt to the
VCS is detected.
• A short circuit of the measuring wires or polarity reversal is not recognised and considered as
if no current is present. This will cause the VCS functioning for restricting current not to work.
Therefore any functions for current restriction must be checked and a secondary protection
against excessive current installed.
• A screened or twisted cable must be used for measuring current. One side must be grounded
if an unscreened cable is used. The cable used for measurement must not be longer than 3
meters.
The current regulation threshold can be finely-adjusted using the potentiometer on the rear
side of the VCS (+5% / -24%).
The potentiometer should be sealed before the VCS is supplied to the customer.
5.8.3 Checking the voltage regulation
Reconnect terminal 50 to the starter motor and start the generator. Monitor the battery voltage
and check that the generator regulates the voltage within the adjusted range. Ensure that the
generator regulates the voltage exactly when switching the load on and off .

ging voltage.
Turning clockwise will increase the char-
ging voltage.
