Not In Remote; Modes Active - Deif GPC-3 Designers Reference Handbook

GPC-3 DRH 4189340587 UK
The value "Setp" can be changed by pressing the up or down arrow. When GOV is underlined, the governor
set point will be changed, and vice versa when the AVR is underlined. When changing the "Setp" value, an
offset will be added to or subtracted from the nominal value. The "Reg." value is the output value from the
regulator. If the genset is running in fixed P/Q, the active or reactive nominal power set point value will be
changed. In fixed frequency/voltage, the nominal frequency or voltage set point will be changed and also dis-
played. When the "Back" button is activated, the regulation set point returns to nominal.
AVR set point manipulation requires option D1.
Regarding AOP setup, refer to "Help" in the PC utility software.

4.16.2 Not in remote

This function can be used for indication, or to raise an alarm in case the system is not in remote. The function
is set up in menu 6370.

4.16.3 Modes active

The GPC-3 is designed to control the generator before, during and after synchronising. However, in rare ca-
ses it may become necessary to deactivate the regulation after the synchronising. This can be the case, for
example if other load sharing equipment is installed or if an external power factor controller is installed. Adjust
this in menu 2500.
The regulation will always be active when the circuit breaker is open. It is only possible to stop
the regulation when the circuit breaker is closed.
Principle
The diagrams below show that the regulation is active until the circuit breaker closes (during synchronising).
When the circuit breaker closes, the regulation will only be active for the selected controller, the governor, the
automatic voltage regulator or none of them.
