This means that the generator AVR must have a voltage droop of 3-4% (voltage dropping 3-4% from no load
to full reactive load when the Multi-line 2 has no control). In order to ensure equal VAr sharing on parallel
running generators, all generators must have the same voltage droop setting.

6.4 Voltage range

6.4.1 Voltage range

When using the analogue interfacing, the resistor installed across the output terminals is selected to obtain
the necessary speed range. The voltage range must be defined similar to the speed range for the governor.
The voltage range must be wide enough for the voltage droop and for the full loading of the genset. A typical
value is +/-10% * U . The necessary control signal level is often specified depending on the AVR type.

6.5 Terminals

6.5.1 Terminals
The AVR can either be prepared for analogue interfacing or digital interfacing. When analogue interfacing is
used, a +/-25 mA or 0-20 mA signal from the Multi-line 2 is applied. This signal can be converted to the nec-
essary voltage level. When the digital interfacing is used, two relays are used as increase/decrease outputs.
The AGC 200 series has no analogue outputs. If analogue outputs are needed, the IOM 200 series external
interface unit must be used.
The terminals must be identified depending on the necessary interfacing. Some general examples are shown
in the illustrations in the chapter "Governor check".
