3 BASIC SAFETY INSTRUCTIONS
Thesesafetyinstructionsdonotconsideranycontingenciesorinci-
dents which occur during installation, operation and maintenance.
Theoperatorisresponsibleforobservingthelocation-specicsafety
regulations,alsowithreferencetothepersonnel.
DANGER
Risk of injury from high pressure and discharge of medium.
▶Beforeworkingonthedeviceorsystem,switchothepres-
sure.Ventordrainlines.
Risk of injury from electric shock.
▶Beforeworkingonthedeviceorsystem,switchothepower
supply. Secure against reactivation.
▶Observeapplicableaccidentpreventionandsafetyregulati-
onsforelectricalequipment.
To prevent injury, ensure the following:
▶Secure device or system to prevent unintentional activation.
▶Onlytrainedtechniciansmayperforminstallationandmain-
tenance work.
▶Performinstallationandmaintenancewithsuitabletoolsonly.
▶Do not make any changes to the device and do not subject it
to mechanical stress.
▶Operatethedeviceonlyinperfectstateandinconsideration
oftheoperatinginstructions.
▶Observethegeneralrulesoftechnology.
▶Install the device according to the regulations applicable in
the respective country.

General information
▶Donotfeedcorrosiveorammablemediaintothedevice
connections.
▶Donotfeedanyuidsintotheconnectionsofthedevice.
▶Aftertheprocessisinterrupted,restartinacontrolledman-
ner.Observesequence:
1. Connect electrical or pneumatic power supply.
2. Charge the device with medium.
▶Observe intended use.
ATTENTION!
Electrostatic sensitive components or 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
minimizeoravoidthepossibilityofdamagecausedbysudden

Electrical installation
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 (3) or (3.1).
▶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.
Exhaust air concept:
▶IncompliancewithdegreeofprotectionIP67,anexhaust
air line must be installed in the dry area.

10 START-UP
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.
