Safety instructions and measures
1 Safety instructions and measures
Intended use
TheSAMSONType3767Positionerismountedonpneumaticcontrolvalvesandusedtoas-
sign the valve position to the control signal. The device is designed to operate under exactly
denedconditions(e.g.operatingpressure,temperature).Therefore,operatorsmustensure
that the positioner is only used in applications where the operating conditions correspond to
the technical data. In case operators intend to use the positioner in applications or conditions
otherthanthosespecied,contactSAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.
ÎRefertothetechnicaldataandnameplateforlimitsandeldsofapplicationaswellas
possible uses.
Reasonably foreseeable misuse
TheType3767Positionerisnotsuitableforthefollowingapplications:
− Useoutsidethelimitsdenedduringsizingandbythetechnicaldata
Furthermore,thefollowingactivitiesdonotcomplywiththeintendeduse:
− Use of non-original spare parts
− Performing maintenance activities not described
Qualications of operating personnel
Thepositionermustbemounted,startedupandservicedbyfullytrainedandqualiedper-
sonnel only; the accepted industry codes and practices must be observed. According to these
mounting and operating instructions, trained personnel refers to individuals who are able to
judgetheworktheyareassignedtoandrecognizepossiblehazardsduetotheirspecialized
training, their knowledge and experience as well as their knowledge of the applicable stan-
dards.
Explosion-protected versions of this device must be operated only by personnel who has un-
dergonespecialtrainingorinstructionsorwhoisauthorizedtoworkonexplosion-protected
devicesinhazardousareas.
Personal protective equipment
No personal protective equipment is required for the direct handling of the positioner. Work
on the control valve may be necessary when mounting or removing the device.

1-2 EB 8355-2 EN
Safety instructions and measures
ÎObservetherequirementsforpersonalprotectiveequipmentspeciedinthevalvedocu-
mentation.
ÎCheck with the plant operator for details on further protective equipment.
Revisions and other modications
Revisions,conversionsorothermodicationsoftheproductarenotauthorizedbySAMSON.
Theyareperformedattheuser'sownriskandmayleadtosafetyhazards,forexample.Fur-
thermore, the product may no longer meet the requirements for its intended use.
Warning against residual hazards
Thepositionerhasdirectinuenceonthecontrolvalve.Toavoidpersonalinjuryorproperty
damage,plantoperatorsandoperatingpersonnelmustpreventhazardsthatcouldbe
caused in the control valve by the process medium, the operating pressure, the signal pres-
sure or by moving parts by taking appropriate precautions. Plant operators and operating
personnelmustobserveallhazardstatements,warningandcautionnotesinthesemounting
and operating instructions, especially for installation, start-up and service work.
If inadmissible motions or forces are produced in the pneumatic actuator as a result of the
supply pressure, it must be restricted using a suitable supply pressure reducing station.
Responsibilities of the operator
Operators are responsible for proper use and compliance with the safety regulations. Opera-
tors are obliged to provide these mounting and operating instructions to the operating per-
sonnel and to instruct them in proper operation. Furthermore, operators must ensure that op-
erating personnel or third parties are not exposed to any danger.
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
wellasthespeciedhazardstatements,warningandcautionnotes.Furthermore,theoperat-
ing personnel must be familiar with the applicable health, safety and accident prevention
regulations and comply with them.

Referenced documentation
Thefollowingdocumentsapplyinadditiontothesemountingandoperatinginstructions:
− The mounting and operating instructions of the components on which the positioner is
mounted (valve, actuator, valve accessories etc.).
1.1 Notes on possible severe personal injury
DANGER
!
Risk of fatal injury due to the ignition of an explosive atmosphere.
Incorrect installation, operation or maintenance of the positioner in potentially explo-
sive atmospheres may lead to ignition of the atmosphere and ultimately to death.
ÎObserveEN60079-14(VDE0165,Part1)forworkonthepositionerinhazard-
ous areas.
ÎWorkinhazardousareasmustonlybeperformedbypersonnelwhohasunder-
gonespecialtrainingorinstructionsorwhoisauthorizedtoworkonexplo-
sion-protecteddevicesinhazardousareas.
ÎReadthespecialinstructionsconcerningexplosionprotection(seesection1.4).
1.2 Notes on possible personal injury
WARNING
!
Risk of injury by possible movement of the actuator stem after connecting the signal
pressure.
ÎDo not touch or block the actuator stem.
Incorrect electrical connection will render the explosion protection unsafe.
ÎAdhere to the terminal assignment.
ÎDo not undo the enameled screws in or on the housing.

Safety instructions and measures
WARNING
!
Intrinsic safety rendered ineffective in intrinsically safe devices.
Every time the positioner is operated, even not within the plant (e.g. during mainte-
nance, calibration and work on equipment), it must be ensured that the conditions for
intrinsically safe circuits are observed.
ÎOnly connect intrinsically safe devices intended for use in intrinsically safe circuits to
certiedintrinsicallysafeinput-connectedunits.
ÎDo not place intrinsically safe devices back into operation that were connected to in-
trinsicallysafeinput-connectedunitswithoutcertication.
ÎDonotexceedthemaximumpermissibleelectricvaluesspeciedintheECtypeex-
aminationcerticateswheninterconnectingintrinsicallysafeelectricalequipment(Ui
or U0, lior I0, Pior P0, Cior C0and Lior L0).
1.3 Notes on possible property damage
NOTICE
!
An incorrect electric signal will damage the positioner.
A current source must be used to power the positioner.
ÎOnly use a current source and never a voltage source.
Incorrect assignment of the terminals will damage the positioner and will lead to mal-
function.
For the positioner to function properly, the prescribed terminal assignment must be ob-
served.
ÎConnect the electrical wiring to the positioner according to the prescribed terminal
assignment.
Risk of malfunction due to failure to comply with air quality requirements.
ÎOnly use supply air that is dry and free of oil and dust.
ÎRead the maintenance instructions for upstream pressure reducing stations.
ÎBlow through all air pipes and hoses thoroughly before connecting them.

1.4 Special instructions concerning explosion protection
Equipment for use in zone2/zone22
ÎInequipmentoperatedaccordingtotypeofprotectionExnAII(non-sparkingequip-
ment)accordingtoEN60079-15:2003,circuitsmaybeconnected,interruptedor
switchedwhileenergizedonlyduringinstallation,maintenanceorrepair.
ÎEquipmentconnectedtoenergy-limitedcircuitswithtypeofprotectionExnLaccord-
ingtoEN60079-15:2003maybeswitchedundernormaloperatingconditions.
ÎThemaximumpermissiblevaluesspeciedinthestatementofconformityoritsad-
denda apply when interconnecting the equipment with energy-limited circuits in type
ofprotectionExnLIIC.
Servicing explosion-protected devices
ÎObserve the following for servicing equipment in a section relevant for explosion pro-
tection:
− Theequipmentmustnotbeputbackintooperationuntilaqualiedinspectorhas
assessed the equipment according to explosion protection requirements, has is-
suedaninspectioncerticateorgiventhedeviceamarkofconformity.Inspection
byaqualiedinspectorisnotrequiredifthemanufacturerperformedaroutine
test on the device before putting it back into operation. Document the passing of
the routine test by attaching a mark of conformity to the device.
− Replace explosion-protected components only with original, routine-tested compo-
nents by the manufacturer.
− Devicesthathavealreadybeenoperatedoutsidehazardousareasandarein-
tendedforfutureuseinsidehazardousareasmustcomplywiththesafetyrequire-
mentsplacedonserviceddevices.Beforebeingoperatedinsidehazardousareas,
testthedevicesaccordingtothespecicationsforservicingexplosion-protected
devices.
