If the regulator is in an alarm state, there will be a yellow indicator next to the corresponding condition causing the
alarmandthestatusindicatorintheheaderwilldisplayayellow“Alarm”state.Iftheregulatorisinafaultstate,
there will be a red indicator next to the corresponding condition causing the fault and the status indicator in the
headerwilldisplayared“Fault”state.Iftheregulatorisinarunstate,therewillbeagreenindicatornexttoall

state. If a given alarm or fault condition is disabled (for example Generator Voltage Imbalance in AVR1 regulation
mode), that condition will display a gray indicator.
Configuration Tab
In this panel there are four tabbed sub panels: Operating Modes (default), Set Points, Protection Settings and CAN
Bus Configuration.
Operating Modes Sub Panel
This panel contains a pull-down menu for selecting Generator Frame Size and radio buttons to change the
configuration of the following settings:
 •RegulationMode(AVR3,FCRorAVR1)
 •CurrentSensingPhases(ThreePhaseorSinglePhase)
 •Excitation(ExcitationOfforExcitationOn)
AVR3 Regulation Mode corresponds to Automatic Voltage Regulation for three-phase generator voltage
sensing.
AVR1 Regulating Mode corresponds to Automatic Voltage Regulation for single phase generator voltage
sensing.
FCR Regulation Mode corresponds to Field Current Regulation. In this mode the regulator will maintain a fixed
level of field current.
Three Phase Current Sensing activates metering of all three phase currents. This sensing mode should only be
selected when using three current transformers.
Single Phase Current Sensing activates metering of phase-B current. This sensing mode should only be
selected when using one current transformer in phase-B. Currents for phases A and C will not be metered.
Excitation Off deactivates excitation to the generator exciter field. The status indicator in the header will display
agray“Off”state.Thisstateisrecommendedformakingadjustmentstotheusersettings.
Excitation Onactivatesexcitationtothegeneratorexcitereld.Iftheregulatorwaspreviously“Off,”selectingthis
state will initiate a new soft start ramp.
Generator Frame Size selects stability settings for the chosen frame size. Settings are displayed with gray num-
bers in the panel. Selecting the appropriate frame size chooses proportional, integral and derivative gain values.
Thesegainvaluesarenoteditable.Foreditablecustomgains,GeneratorFrameSize“CUST”shouldbeselected.
Choosing“CUST”willcopythegainsfromthepreviousframesize.Thegrayedgainswillthenbecomeactivefor
editing. Saving to EEPROM will store the edited gains to the user settings.
