Basic safety instructions
General hazardous situations.
Topreventinjury,ensure:
▶Inthepotentiallyexplosion-riskareathepositionerType8696
maybeusedonlyaccordingtothespecicationontheseparate
approvalsticker.Foruseobservetheadditionalinstructions
enclosedwiththedevicetogetherwithsafetyinstructionsfor
theexplosion-riskarea.
▶Deviceswithoutaseparateapprovalstickermaynotbeused
inapotentiallyexplosivearea.
▶Installationandrepairworkmaybecarriedoutbyauthorized
technicians only and with the appropriate tools.
▶Afteraninterruptioninthepowersupplyorpneumatic
supply,ensurethattheprocessisrestartedinadenedor
controlled manner.
▶Thedevicemaybeoperatedonlywheninperfectcondition
andinconsiderationoftheoperatinginstructions.
▶Thegeneralrulesoftechnologyapplytoapplicationplanning
andoperationofthedevice.
Topreventdamagetopropertyofthedevice,ensure:
▶Donotfeedanyaggressiveorammablemediaintothepilot
air port.
▶Donotfeedanyliquidsintothepilotairport.
▶When unscrewing and screwing in the body casing or the
transparentcap,donotholdtheactuatoroftheprocessvalve
buttheconnectionhousingofType8696.
▶Donotputanyloadsonthehousing(e.g.byplacingobjects
on it or standing on it).
▶Donotmakeanyexternalmodicationstothedevice

NOTE!
Electrostatic sensitive components / modules.
The device contains electronic components which react sen-
sitively to electrostatic discharge (ESD). Contact with electro-
statically charged persons or objects is hazardous to these
components.Intheworstcasescenario,theywillbedestroyed
immediatelyorwillfailafterstart-up.
▶ObservetherequirementsinaccordancewithEN61340-5-1to

7.2 Installation of the positioner on process
valves of series 2103 and 23xx
NOTE!
When mounting on process valves with a welded body,
follow the installation instructions in the operating instruc-
tions for the process valve.
Whenthepositionerisbeinginstalled,thecolletsofthe
pilotairportsmustnotbettedtotheactuator.
NOTE!
Damaged printed circuit board or malfunction.
▶Ensurethatthepuckissituatedatontheguiderail.
→Align the puck and the positioner until
1. thepuckcanbeinsertedintotheguiderailofthe
positioner (see “Fig.6”) and
2. theconnectionpiecesofthepositionercanbeinserted
intothepilotairportsoftheactuator(seealso“Fig.7”).

NOTE!
Too high torque when screwing in the fastening screw does
not ensure protection class IP65 / IP67.
▶Thefasteningscrewsmaybetightenedtoamaximum
torqueof1.5Nmonly.
→Attachthepositionertotheactuatorusingthetwosidefas-

DANGER!
Risk of injury from high pressure in the equipment/device.
▶Beforeworkingonequipmentordevice,switchothepressure
anddeaerate/drainlines.
Procedure:
→Connect the control medium to the pilot air port (1)
(3–7bar;instrumentair,freeofoil,wateranddust).
→Attach the exhaust airline or a silencer to the exhaust air port
(3)
(see “Fig.8:Pneumaticconnection”).
Keeptheadjacentsupplypressurealways atleast0.5–
1barabovethepressurewhichisrequiredtomovethe
actuator to its end position. This ensures that the control
behaviorisnotextremelynegativelyaectedintheupper
strokerangeonaccountoftoolittlepressuredierence.
During operation keep the uctuations of the pressure
supplyaslowaspossible(max.±10%).Ifuctuationsare
greater, the control parameters measured with the X.TUNE
functionarenotoptimum.
Importantinformationfortheproblem-freefunctioningof
thedevice:
▶Theinstallationmustnotcausebackpressuretobuild
up.
▶Select a hose for the connection with an adequate
cross-section.
▶Theexhaustairlinemustbedesignedinsuchawaythat
nowaterorotherliquidcangetintothedevicethrough
the exhaust air port.

10.1 Safety instructions
WARNING!
Risk of injury from improper operation.
Improper operation may result in injuries as well as damage to
thedeviceandtheareaaroundit.
▶Beforestart-up,ensurethattheoperatingpersonnelare
familiarwithandcompletelyunderstandthecontentsofthe
operating instructions.
▶Observethesafetyinstructionsandintendeduse.
▶Only adequately trained personnel may operate the equip-
ment/thedevice.
10.2 Automatic adjustment X.TUNE
To adjust the positioner to local conditions, the X.TUNE
functionmustberunfollowinginstallation.
WARNING!
Danger due to the valve position changing when the X.TUNE
function is running.
When the X.TUNE is running under operating pressure, there is
anacuteriskofinjury.
▶NeverrunX.TUNE while a process is running.
▶Takeappropriatemeasurestopreventtheequipmentfrom
beingaccidentallyactuated.

NOTE!
Avoid maladjustment of the controller due to an incorrect
pilot pressure or applied operating medium pressure.
▶Run X.TUNE wheneverthepilotpressure(=pneumaticaux-
iliaryenergy)isavailableduringsubsequentoperation.
•RuntheX.TUNEfunctionpreferablywithoutoperatingmedium
pressuretoexcludeinterferencecausedbyowforces.
To run X.TUNE,thepositionermustbeintheAUTOMATIC
operatingstatus(DIPswitch4=OFF).
NOTE!
Breakage of the pneumatic connection pieces due to rota-
tional impact.
▶When unscrewing and screwing in the transparent cap, do
notholdtheactuatoroftheprocessvalvebuttheconnection
