todetectpressureloss inthe systeminduetime.
The unitmustonlybeusedwithinthescopeof itstechnicaldata. Appropriateusealso
includescompliancewiththeconditionsthe manufacturerhasspecified for

1.3Safetyinformation
Thismanualdescribesthe function,applicationand safetyconsiderationsofthis
product.Thismanualmustbereadandunderstoodbeforeanyattempt ismade
toinstall oroperatetheproduct, otherwisedamagetotheproductorunsafe
conditionsmayoccur.
Thisdevicecomplies withpart15 oftheFCC Rules andwithRSS-210 ofIndustry
Canada.Operation issubjecttothefollowing twoconditions.
(1)thisdevice may notcause harmfulinterference,and
(2)thisdevice mustacceptanyinterference received, includinginterference that
may cause undesiredoperation.
1. The radiolinkestablished bythe systemcan experiencetemporary orpermanent
interferencethrough external influences. Asaresult, the statesof the sensorsarenot
updated at the receiverforthe duration ofthe interference.The interferenceisonly
reported bythe receiverafterthe watchdog timehaslapsed. Ensurethat such
interferencescannot causeanydamage.Adjust the watchdog timetoatimesuitablefor
yourprocess.
The customarystandardsforsensorsystemsmust be observed.
Installation and commissioning mayonlybe performed byqualified staff trained for
electricalsystem.

2. Inthe 824 MHzrange,the systemdoesnot complywiththe EMCregulation for
interferenceimmunitytoincomingradiowaves. Lossesofradiotelegramsmayoccurin
thisrange.
Disturbancesbecomemorelikelyifthe antenna isfurtherthan 25 cmawayfromthe
receiver.The applicationmust thereforebe tested eachtimebeforebeing integrated.
3. Theradio switchreceiver mustnotbeusedin combinationwithdevices thatare
directlyorindirectlyusedtosafeguardthehealthorlifeofpersons,ordevices
which,wheninoperation, couldcause danger topersons, animalsorproperty!
Thisisdueto theradio switch receiver’sclassificationas “Class 2Equipment” in
accordance with ETSIEN301 489-3V1.4.1(2202-08)“Specificconditionsfor
short-rangedevices (SRD)”.
4. Whenthe chuckisinoperation, sudden surgesinpressuremayoccurinthe piston area
of the chuck.Ifthe switching pressureset isexceeded due tothesepressure
fluctuations,then the systemsendsthisinformation.Thus, avery short “PressureIO”
message mayariseduring the clamping process.
5. Even if theairsupplyisswitched off,theremaystillbe pressurepresent at the pressure
switchifthe chuck wasnot bled.Itisimperativethatthe pressurechamberbe bled
beforethe pressureswitchisdisassembled.The chuckmust be opened forthis
purpose.
The timebetween evaluabletelegramsmust be at least 50ms.
6. The RSS R1/P1receiver/transmitterhasbeen built according tothe currentstateof the
art and isoperationallysafe.The unit canonlyposehazardsif, forexample:
-the unit isused, assembled ormaintained inappropriately.
-the unit isused forpurposesotherthan thoseforwhichitisintended.
-the ECMachine Directive,the accident prevention regulations, the VDEguidelines,
orthe safetyinformationand assemblynotesarenot observed.
7. Allpersonsresponsibleforassembly,commissioning and maintenanceof the unitare
obliged tohaveread and understood allthe operating instructions,inparticularthe
Safety chapter.Werecommend thatthe customerhavethisconfirmed inwriting
8. The installation and deinstallation,connection and commissioningofthe unitmayonly
be performedbyauthorized, appropriatelytrained personnel.
9. Modesofoperation and work methodsthat adverselyaffectthe function and/orthe
operationalsafetyofthe unit aretobe refrained from.
10. The RSS R1/P1receiver/transmittermayonlybe used tocontrol chuckswithinthe
scope ofitstechnical data.Anyuseoutside thisscope isdeemedtobe inappropriate.
The manufacturerassumesno liabilityforanyinjuryordamage resulting fromsuch
inappropriateuse.
11. Always disconnectthepower supplylines duringassembly, conversion,
maintenance and adjustmentwork.
12. Additionalholes,threadsorattachmentswhich are notsuppliedas accessories
bySCHUNK may onlybeapplied after obtainingthepriorconsentofSCHUNK.
