Manualoperaonrequiresthepresenceoftwomomentarypushbuons,oneforeachofthe
twonaturalvenlaonzones,withthreecontacts:common,openandclose(seediagram4
onpage50).
Themanualcommandsaredisabledifanemergency,weather,thermostatorCO2signalhas
beenacvated.Thecontrolunitcanbeconguredsothatthemanualcommandsworkonan
impulsebasis(bypushingthebuonandreleasingitwithin1second),or“deadman”basis
(thecommandremainsacveforaslongasthebuonishelddown).Tochoosethetypeof
operaon,seetheparagraph8.2“INITIALCONFIGURATION”.

Anopeningcommandsenttotheactuatorbymanualcommands,doesnotresultinanytype
ofsignal.
Theopencommandceases:
a.Whenthemaximumstrokemeof180secondsisreached(impulseoperaon)orwhenthe
manualbuonisreleased(personpresentoperaon).
b.Whentheresetbuonispushed(thedrivestops).
c.Impulseoperaon:thedrivestopswhentheclosebuonispushedandreleasedwithin1second.
d.Whenanemergencyofweathereventoccurs(dependingonthesituaon,thedrivechangesdireconorexecutesemergency
opening/closing).
TheEMERGENCYINTERLOCKstatusisacvatedbysupplying24Vdc+/-25%externalvoltage
totheAUX1input(forexample,comingfromthemotoroutputofanothercontrolunitC-SV)
anditissignalledbyaflashingredLED.ItworksonlyifthecontrolunitisconguredinINTER-
LOCKSLAVEmode(seedip-switchconguraonpar.8.2)andifthecontrolunitisnotalready
inemergencystatus.
ThecontrolunitentersintheEMERGENCYINTERLOCKstatus2secondsaertheenablingof
AUX1inputanditremainsinthisstatusunlaRESETcommandisgiven;thecontrolunitgoes
into standby mode.
WhenthecontrolunitisinEMERGENCYINTERLOCKstatus,itgivesaclosingcommandtothemotorsanditignoresanyemergency
command(seediagram10onpage53).

Theresetcommandcanbeacvatedusingtheemergencypushbuonor(duringinstallaon
/maintenance/tesng)directlyonthecontrolunit’selectronicboard.Thiscontrolworks
onlywhenthepushbuonisreleased.
Resengallowsthecontrolunittoexittheemergencysituaon,providedtheeventthat
gaverisetothealarmhasceased.Duringtheresetphase(about1second)allthreeLEDs(red,
yellowandgreen)stayon,makingitpossibletovisuallycheckthattheyareactuallyworking.
Inthefactorysengs,thedoublepressingoftheRESETbuoncommandsthewindowsto
close(seesecon8.2).
TheEM CL inputisused to sendanemergencyclosingcommand. This isusedinsome
countriestosuocateflamesandfacilitatetheFireBrigade’sacons,oncethebuildinghas
been evacuated.
It must be terminated with a 10 kOhm resistor.
Whenused,itmustbeconnectedtooneormoremanualcontrolpoints(normallyopen
contacts)inparallelwithoneanother,eachwitha1kOhmresistorinserieswithit.
Ashort-circuitorbreakinthecableisindicatedasafaultonthecontrolunit,anddoesnotinfluencetheotherfuncons.
