◦ Two regulation digital outputs (AVR increase and AVR decrease).
◦ One regulation analogue output (AO or PWM, AVR output [%]).
• If an analogue AVR regulation output is used, the slope of the output curve must be positive.
◦ That is, there must be a lower AVR output % for a lower voltage or current, and a higher AVR output % for a higher voltage or
current.
• No AVR regulation outputs on any other hardware modules.
• A Manual AVR increase digital input on the GAM3.2.
• A Manual AVR decrease digital input on the GAM3.2.
• The Regulators > AVR > Modes > Stand-alone mode digital input on the GAM3.2.
Configure the parameters under Configure > Parameters > Regulators > AVR general configuration > Stand-alone
configuration error.

6.8 Regulation alarms
6.8.1 GOV regulation error
This alarm shows when there is an error with the governor controlled regulation.
The alarm is based on the difference between the measured value and the required set point, as a percentage of the set point. The
larger the set point, the more the measured value is allowed to differ from the set point.
The alarm activates if the measured value is outside of the permitted range for longer than the delay.
INFO
This alarm is not activated when the genset frequency swings in and out of the permitted range above and below the set
point. This is because this alarm only activates when the measured value is constantly above the upper limit, or constantly
below the lower limit for the entire delay period.
Configure the parameters under Configure > Parameters > Regulators > GOV monitoring > Regulation error.
INFO
Do not set the alarm set point lower than the deadband percentage for relay regulation. Doing so might activate the alarm
in an area where regulation is not possible.
