2 AUTHORIZED USE
Non-authorized use of the positioner Type 8692 and the
process controller Type 8693 can be dangerous to people,
nearby equipment and the environment.
Thedeviceisdesignedtobemountedonpneumaticactuators
ofprocessvalvesforthecontrolofmedia.
▶Inapotentiallyexplosivearea,Type8692and8693maybeused
onlyinaccordancewiththespecicationontheseparateEx
ratingplate.Fortheuse,observetheATEXmanualwithsafety
instructionsfortheExarea.
▶DeviceswithoutaseparateExratingplatemaynotbeusedin
apotentiallyexplosivearea.
▶Donotexposethedevicetodirectsunlight.

•Localsafetyregulations–theoperatorisresponsibleforobserving
theseregulations,alsoinrelationtotheinstallationpersonnel.
Risk of injury from high pressure in the system/device.
▶Beforeworkingonthesystemordevice,switchothepres-
sureandvent/drainlines.
Risk of electric shock!
▶Beforereachingintothedeviceortheequipment,switcho
thepowersupplyandsecuretopreventreactivation.
▶Observeapplicableaccidentpreventionandsafetyregula-
tionsforelectricalequipment.
General hazardous situations.
Topreventinjuries:
▶Ensurethatthesystemcannotbeactivatedunintentionally.
▶Thedevicemustonlybeoperatedwheninaperfectcondi-
tionandinconsiderationoftheoperatinginstructions.
▶Installationandmaintenanceworkmaybecarriedoutonly
byauthorizedtechnicianswiththeappropriatetools.
▶Afteraninterruptionintheelectricalorpneumaticsupply,
ensurethattheprocessisrestartedinadenedorcontrolled
manner.
▶Thegeneralrulesoftechnologymustbeobservedforappli-
cationplanningandoperationofthedevice.

DANGER!
Risk of injury from high pressure in the system/device.
▶Beforeworkingonthesystemordevice,switchothepres-
sureandvent/drainlines.
Observe the following for the proper functioning of the
device:
▶Theinstallationmustnotcausebackpressuretobuild
up.
▶Tomaketheconnection,selectahosewithsucient
cross section.
▶Designtheexhaustairlineinsuchawaythatnowater
orotherliquidcangetintothedevicethroughthe
exhaustairport(3or3.1).
Exhaust air concept:
▶IncompliancewiththedegreeofprotectionIP67,an
exhaustairlinemustbeinstalledinthedryarea.
▶Alwaysmaintainanappliedcontrolpressureofat
least0.5...1barabovethepressurewhichisrequired
tomovethepneumaticactuatortoitsendposition.
Thisensuresthatthecontrolbehaviorisnotnegatively
aectedintheupperstrokerangeonaccountoftoo
littlepressuredierence.
▶Duringoperation,keeptheuctuationsofthecontrol
pressureaslowaspossible(max.±10%).
Ifuctuationsaregreater,thecontrolparametersmea-
suredwiththeX.TUNEfunctionarenotoptimum.
