Parameter
Range
Default Notes
To set this parameter, start with
AVR output offset
= 0 %. Change the offset value in
small increments to fine tune the voltage output of the genset. When you reach the
desired genset voltage output, the offset is tuned.
6.6.3 AVR relay regulation parameters
You can configure relay outputs on the controller to regulate the AVR. You can also set a number of parameters for the AVR relay
regulation function.
Wiring example
Regulators > AVR > Control > AVR increase
Regulators > AVR > Control > AVR decrease
G
Outputs
You must assign these outputs under
Configure > Input/output
. Select the hardware module, then select a digital output to
configure.

Function
I/O
Type
Details
Regulators > AVR > Control >
AVR increase
Digital output
Variable-length
pulse
The controller activates this output to send a signal to the
AVR to increase the voltage or reactive power.
Regulators > AVR > Control >
AVR decrease
Digital output
Variable-length
pulse
The controller activates this output to send a signal to the
AVR to decrease the voltage or reactive power.
Parameters
INFO
To see these parameters, you must assign the functions to digital outputs.
Configure the AVR regulation parameters for automatic regulation under
Configure > Parameters > Regulators > AVR relay
configuration > Automatic configuration
.
These parameters adjust the controller's relay control output.

Default Notes
Period time
50 ms to
15 s
500 ms
You can make the AVR response faster by decreasing the
Period time
. However, if the rest
of the system is slow anyway, then decreasing the
Period time
will provide no additional
benefits.
