AGC
Please notice that the set point of the mains power export can be adjusted to 0
kW. This means that the gen-set will be parallel to the mains but no power
import or export.
Semi-auto description
When the generator breaker is closed and the mains breaker is opened, the unit will use the
nominal frequency as setpoint for the speed governor. If AVR control (option D1) is selected the
nominal voltage is used as setpoint.
When the generator is paralleled to the mains, it will be controlled according to the mains power
export setpoint. If AVR control (option D1) is selected, the setpoint is the adjusted power factor
(6550 Fixed power setpoint).
See general semi-auto mode description on page 19.
Test mode description
See general test mode description valid for all gen-set modes on page 20.
Manual mode description
See general manual mode description valid for all gen-set modes on page 21.
Block mode description
See general block mode description valid for all gen-set modes on page 21.
General semi-auto mode description
The unit can be operated in semi-automatic mode. Semi-auto means that the unit will not initiate
any sequences automatically, as is the case with the auto mode. It will only initiate sequences, if
external signals are given.
An external signal may be given in three ways:
1. Push-buttons on the display are used
2. Digital inputs are used
3. Modbus command.
The standard AGC is only equipped with a limited number of digital inputs,
please refer to page 95 in this document and the data sheet for additional
information about availability.
