INFO
If an analogue input is configured, the Modbus value for the external offset will reflect the analogue input value. The
Modbus external offset cannot be configured until the analogue input for the external offset is cleared.
AVR parameters
You can configure the governor common settings under
Configure > Parameters > Regulators > AVR general configuration
.
INFO
To see these parameters, you must assign an AVR output function.
External offset
These parameters allow analogue inputs to determine the genset's voltage, reactive power or cos phi set point.
