Thissectionprovidesanoverviewofthecomponentsandfunctionsofthecontroller'ssupportforACand
DCgenerators.
AgeneratorisaspecializedtypeofACorDCsourcewhichcanautomaticallycontrolthestartingand
stoppingofageneratorwiththeuseofarelay,basedonstartandstopconditionsspecified.
Bycustomizingthestartandstopconditions,theusercanadjustthegeneratorcontrolfortheirspecific
situation.Forexample,startandstopconditionscanbeaddedwhichrunthegeneratorbasedona
scheduleinordertoexercisethegenerator.
ThegeneratorhasabuiltinandconfigurableMinimum Runtime toprotectthegeneratorfromshort

generatortorunfortheminimumruntimebeforeitcommandsthegeneratortostop.
ThegeneratorensuresstableoperationwithitsconfigurableEquation Stability Delay.Forexample,
whileastartconditionmaybecometrue,theCall to Start willevaluatealltheenabledstartconditions
forthelengthoftheEquation Stability Delay beforeitbecomestrue.Thismeansthatifachangein
thedependentstartorstopconditionsisnotstablefortheconfiguredtime,itwillnotaffectthegenerator
control.Thiseffectivelyfiltersoutsensornoiseandfurtherprotectsthegeneratorfromfrequentandshort
startupcycles.
Severalstatisticsareavailabletogiveinsightintothehistoricalbehaviorofthegenerator.Bydefault,the

Intheeventofhardwaremalfunctionormisconfigurations,severalalarmsaresuppliedwiththegenerator

14.1. Create an AC generator
To create an AC generator:
1. IfanACsourcesystemdoesnotalreadyexist,createitatSystems > Add or Remove Systems
andlaunchtheCreate System wizard.SelecttheAC Source System fromthedropdownlistand
finishthewizard.
2. GotoSystems > AC Source System > Inventory.
3. IntheAC Sources table,selectAdd AC Source.TheAdd AC Source wizardwilllaunch.
4. SettheName andthenselectNext.
5. SelectGenerator fromtheAC Source Type dropdownlist.SelectNext.
6. SelectthePhase foryourAC Source.SelectNext.
7. OntheAlarms page,selectwhethertheACInputFailalarmshouldbeenabledforthissource.
SelectYes orNo.
