alockablecover,andhas2positions;VFDandBYPASS.Ifthemodeswitchchangespositionwhilethe
motorisrunning,themotorwillstopandrestartinthenewmode
VFD MODE
Thisisthenormalmodeofoperation.ThecontrollerwillusetheVFDastheprimarystartingmeans,and
automaticallyswitchtothebypassstartingmeansincaseofaVFDalarm.Oncethecontrollerhasauto-
maticallyswitchedtothebypassstartingmeans,itwillremaininthisstateuntiltheVFDalarmsare
manuallyreset.
Note: When the motor is driven by the VFD, it may run at minimum speed when the system
pressure is above the set point pressure.
BYPASS MODE
Ifrequired,thebypassstartingmeanscanbemanuallyselectedusingthemodeswitch.
METHODS OF STARTING
AUTOMATIC START
Thecontrollerwillstartautomaticallyonlowpressuredetectionbythepressuresensorwhenthepres-
suredropsbelowthecut-inthreshold.
MANUAL START
Themotorcanbestartedbypressingthemanualstartpushbutton,regardlessofthesystempressure.
REMOTE MANUAL START
Themotorcanbestartedfromaremotelocationbymomentarilyclosingacontactofamanualpush-
button.
REMOTE AUTOMATIC START, DELUGE VALVE START
Themotorcanbestartedfromaremotelocationbymomentarilyopeningacontactconnectedtoan
automaticdevice.
EMERGENCY START
Themotorcanbestartedmanuallybyusingtheemergencyhandle.Thishandlecanbemaintainedina
closedposition.
Important: to avoid damaging the contactor, it is recommended to start the motor in this
manner:
1. Shutdownthemainpowerbyusingthemaindisconnectmeans,
2. Pulltheemergencystarthandleandlockitinclosedposition,
3. Turnthepowerbackonbyusingthemaindisconnectmeans.

V2024.02 14
SEQUENTIAL START
Incaseofamultiplepumpapplication,itmaybenecessarytodelaytheautomaticstartingofeach
motortopreventsimultaneousstartingofallmotors.
TEST START
Themotorcanbestartedintestmodemanuallybypressingtheruntestpushbutton,orautomatically
byusingtheperiodictestfeature.
METHODS OF STOPPING
MANUAL STOP
Manualstopisdonebypressingtheprioritystoppushbutton.Notethatpressingthestoppushbutton
willpreventthemotorfromrestartingaslongasthebuttonispressed,plusatwoseconddelay.This
actionhaspriorityoveranyactivedemand,butthemotorwillrestartautomaticallyoncethebuttonis
releasedifthereisany.
AUTOMATIC STOP
This function is never activated by default and must be authorized by the authority having
jurisdiction prior to activating.
Automaticstopispossibleonlyafteranautomaticstart.Whenthisfunctionisenabled,themotoris
automaticallystopped10minutesaftertherestorationofthepressuregiventhatnootherruncauseis
present.The10minutesdelayisadjustable.
EMERGENCY STOP
Theemergencystopisalwayspossibleinanystartingconditionandisdonebyusingthemaindis-
connectingmeanslocatedonthedoor.

TRANSFER SWITCH OPERATION SEQUENCE
Thetransfer-switchshallbesuppliedeitherbyasecondutilityorbyanon-sitestandbygeneratorcom-
plyingwiththerequirementsofaLevel1,Type10,ClassXsystemofNFPA110,meaningitshallsupply
powertothefirepumpcontrollerwithin10seconds.
Additionally,thefirepumpcontrollershallbefullyoperationalandreadytostartwithin10seconds
aftertheapplicationofpower.Thosetworequirementscombinedmeansthatthetotaltimeframe
betweenanormalpowerlossandathecontrollerbeingreadytostartonthealternatepower,if
providedbyagenerator,shallbeatmost20seconds.
TRANSFER TO ALTERNATE POWER SOURCE
Whenthenormalpowersourceisoutsideacceptableparametersforatleastthreeseconds,agenerator
startcommandisissued.Thethreeseconddelaycanbeadjustedtohelpmeetthe10secondsrequire-
mentofthegenerator,but doing so increases the risk of nuisance starting of the generatorincaseof
powerbrownouts.Specialconsiderationmustbetakenbeforeeditingthisvalue.
Oncethealternatepoweriswithinacceptableparametersforatleastanotherthreeseconds,thetrans-
fertothealternatepowersourceisinitiated.
RE-TRANSFER TO NORMAL POWER SOURCE
The transfer switch will stay in alternate position, if the motor is running, for as long as the
alternate power source is within acceptable parameters. The re-transfer sequence is enabled
if the motor is not running.
Whenthenormalpowersourceiswithinacceptableparametersforatleastfiveminutes,there-transfer
tothenormalpowersourceisinitiated.Acool-downperiodoffiveminutesmaintainsthegeneratorrun-
ningafterwhichitsstartcommandwillberemoved.
TEST TRANSFER SEQUENCE
Afulltransfersequencecanbeexecutedbymeansofpressingthetransfer-switchtestmembranebut-
ton.
MANUAL OPERATION
Thetransfer-switchisdesignedtobekeptinautomaticmodeatalltimes.Incertainemergencysitu-
ationsrequiringit,thetransfer-switchcanbemanuallyoperated.
Thereis180°betweentheNormalposition(I)andtheAlternateposition(II).Tooperatemanuallythe
