3. General and operaonal descripon

Therelayisforevaluangsensors,includingsafetycontactmats,safetycontactstripsandsafetybumpers

formakingsafepinchandshearpoints.

Two separate signalling circuits can be connected to the relay, each controlling a switching output. The

quiescentcurrentmonitorofthesensorisenabledbyanintegratedterminatorinthesensor.

Therelaymonitorsthesetwosignallingcircuitspermanentlyforacvaonorbreaking(cablebreak).Ifthe

expectedquiescentcurrentisowing,theoutputrelaysareoperatedandtheswitchcontactsareclosed.If

thesensorisacvatedorthesensorcircuitisbroken,therelayswitchcontactsopen.

TherelayisdesignedinaccordancewithENISO13849-1:2015forCategory3.TocomplywithCategory3

therelayismanufacturedredundantandwithtwomutuallyacvangforciblyguidedsafetyrelays.

ThemonitoringstateofthesensorandtheoperangvoltagesuppliedareshownbyLEDs.

Intheeventofafaultalarm,allsafetyoutputsareinacve.

Theunitcan beusedina household environment as wellasan industrialenvironmentup to

analtudeof2000mabovemeansealevel.Theunitmustnotbeoperatedinareaswithmajor

temperature changes.

4. Intended use

Therelayisabletofullitssafetytaskonlyifitisusedforthepurposeitwasdesignedfor.

Appropriateulisaonoftherelayisuseasaprotecvedeviceincombinaonwithsafetycontactmats,

safetybumpersandsafetycontactstripsof8.2kΩresistancetoquiescentcurrentmonitoring.

Anyulisaonbeyondthis does notconstuteappropriateintendeduse. The manufactureraccepts no

liability for damage arising from inappropriate use.

Useinspecialapplicaonsrequirestheapprovalofthemanufacturer.

Theuseofthesafetyrelayatheightsabove2000mabovesealevelorinpotenallyexplosiveareasisnot

8.1 Supply voltage

The supply voltage is to be connected to the terminal pair 8 924VAC/DC.Thesupplywiringtotherelaymust

beprotectedbyasuitablecircuitbreaker.Thesupplyvoltagemustmeettherequirementsforlowvoltage

8.2 Sensor connecon

Connect the sensor for Channel 1 to the terminal pair 3 11. Connect the sensor for Channel 2 to the terminal

pair 3 10.

Ifachannelisnotused,itmustbeedwithan8.2kΩresistance.

8.3 Connecng mulple sensors per sensor circuit

ASO sensors must not be connected in parallel.

One or more sensors can be connected to sensor input. For this purpose, the individual sensors are connec-

tedinseriesaccordingtogure1.

Safety edges SENTIR edge:

UptoveSENTIRedgemaybeconnectedinseries.ThemaximumtotallengthotheSENTIRedgeshall

8.4 Connecng control circuits

The control circuit to be monitored for Channel 1 is to be connected to the terminal pair 4, 5and the corre-

sponding control circuit for Channel 2 is to be connected to the terminal pair 6, 7.

Thecontrolcircuitsmustbeprotectedbyacorrespondingcircuitbreakerdependingontheratedcurrentor

theratedcurrentinthecontrolcircuitsmustbelimitedtothemaximumvaluebyothermeans.

Therelaycontactmayonlyswitchextralowvoltages(30V).Theswitchingoflowvoltages(230V)

is not permissible.

9. Commissioning and performance tesng

Aeralltheelectricalcontactshavebeenconnectedandthesupplyvoltageswitchedon,theplant/machinery

mustbetestedforproperfunconing.

Followingsuccessfulcommissioningthesafetyoutputs4, 5and 6, 7areacvated(relaycontacts“closed”).

Acvangtheannunciatorresultsinopeningtherelaycontacts.

Thesafetysystemmustbetestedbyqualiedstaatappropriateintervals.Thetesngmustbecomprehen-

siblydocumentedatallmes.Therequirementsoftheplant/machinerymanufacturermustbeobserved

and adhered to.

10. Error diagnosis

Ifthewiringandconnecngupofthesupplyvoltageiscorrect,onlythegreenLEDPowershouldlightup.Ifthe

redLEDlightsupthereisafaultinthesystem,whichcanbeisolatedwiththeaidoftheLED.

* Ifthefaultisnotinthewiring,thefunconingoftheelectronicsmaybecheckedbyngan8.2kΩ

resistancetotheannunciatorinputontherelay.Iftheelectronicsthenworkproperly,theannunciator

mustbetestedwithanohmmeter.Forthistheconneconbetweentheannunciatorandtherelaymust

bedisconnectedandconnectedtoanohmmeter.Withaninacvatedannunciatortheresistanceshould

be8.2kΩ±500Ω.Iftheannunciatorisacvated,theresistanceshouldnotexceed500Ω.

11. Decommissioning and disposal
