1 Safety instructions and measures
Intended use
TheSAMSONTROVIS3730-1Positionerismountedonpneumaticcontrolvalvesandis
used to assign 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 other
applicationsorconditionsthan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forlimitsandeldsofapplicationaswellaspossibleuses.
Reasonably foreseeable misuse
TheTROVIS3730-1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speciedbySAMSON
Qualications of operating personnel
Thepositionermustbemounted,startedupandservicedbyfullytrainedandqualied
personnel only; the accepted industry codes and practices are to 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 standards.
Explosion-protected versions of this device are to 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.

EB 8484-1 EN 7
Safety instructions and measures
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.
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.
Safety features
Upon failure of the air supply or electric signal, the positioner vents the actuator, causing the
valve to move to the fail-safe position determined by the actuator.
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. They must observe all hazard
statements, warning and caution notes in these mounting and operating instructions, espe-
cially 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
The operator is responsible for proper operation and compliance with the safety regulations.
Operators are obliged to provide these mounting and operating instructions to the operating
personnel and to instruct them in proper operation. Furthermore, the operator must ensure
that operating personnel or third persons 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.

Safety instructions and measures
Servicing explosion-protected devices
If a part of the device on which the explosion protection is based needs to be serviced, the
devicemustnotbeputbackintooperationuntilaqualiedinspectorhasassesseditaccord-
ingtoexplosionprotectionrequirements,hasissuedaninspectioncerticate,orgiventhe
deviceamarkofconformity.Inspectionbyaqualiedinspectorisnotrequiredifthemanu-
facturer performs 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ex-
plosion-protected components only with original, routine-tested components by the manufac-
turer.
Devices that have already been operated outside hazardous areas and are intended for fu-
ture use inside hazardous areas must comply with the safety requirements placed on serviced
devices. Before being operated inside hazardous areas, test the devices according to the
specicationsforservicingexplosion-protecteddevices.
Maintenance, calibration and work on equipment
ÎOnlyuseintrinsicallysafecurrent/voltagecalibratorsandmeasuringinstrumentsforin-
terconnection with intrinsically safe circuits to check or calibrate the equipment inside or
outside hazardous areas.
ÎObservethemaximumpermissiblevaluesspeciedinthecerticatesforintrinsicallysafe
circuits.
Referenced standards and regulations
DeviceswithaCEmarkingfullltherequirementsoftheDirectives2014/30/EUand
2014/34/EU.Thedeclarationsofconformityareincludedattheendoftheseinstructions.

Safety instructions and measures
1.1 Notes on possible severe personal injury
DANGER
!
Risk of fatal injury due to the formation of an explosive atmosphere.
Incorrect installation, operation or maintenance of the positioner in potentially explosive
atmospheres may lead to ignition of the atmosphere and cause death.
ÎThefollowingregulationsapplytoinstallationinhazardousareas:EN60079-14
(VDE0165,Part1).
ÎInstallation, operation or maintenance of the positioner must only performed by per-
sonnel who has undergone special training or instructions or who is authorized to
work on explosion-protected devices in hazardous areas.
1.2 Notes on possible personal injury
WARNING
!
Risk of personal injury due to moving parts on the valve.
During initialization of the positioner and during operation, the actuator stem moves
throughitsentiretravelrange.Injurytohandsorngersispossibleiftheyareinserted
into the valve.
ÎDuringinitialization,donotinserthandsorngersintothevalveyokeanddonot
touch any moving valve parts.
1.3 Notes on possible property damage
NOTICE
!
Risk of damage to the positioner due to incorrect mounting position.
ÎDo not mount the positioner with the back of the device facing upward.
ÎDo not seal or restrict the vent opening when the device is installed on site.

10 EB 8484-1 EN
Safety instructions and measures
Risk of malfunction due to incorrect sequence during start-up.
The positioner can only work properly if the mounting and start-up are performed in the
prescribed sequence.
ÎPerformmountingandstart-upasdescribedinsection5onpage34.
An incorrect electric signal will damage the positioner.
A current source must be used to provide the electrical power for 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.
Malfunction due to initialization not yet completed.
The initialization causes the positioner to be adapted to the mounting situation. After ini-
tialization is completed, the positioner is ready to use.
ÎInitializethepositionerontherststart-up.
ÎRe-initializepositionerafterchangingthemountingposition.
Risk of positioner damage due to incorrect grounding of the electric welding
equipment.
ÎDo not ground electric welding equipment near to the positioner.
