Safety instructions and measures
1 Safety instructions and measures
Intended use
TheSAMSONTROVIS3730-3Positionerismountedonpneumaticcontrolvalvesandused
to assign the valve position to the control signal. The device is designed to operate under ex-
actlydenedconditions(e.g.operatingpressure,temperature).Therefore,operatorsmusten-
sure that the positioner is only used in applications where the operating conditions corre-
spond to the technical data. In case operators intend to use the positioner in other applica-
tions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3730-3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 in these instructions
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.

1-2 EB 8484-3 EN
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. 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.

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 ultimately to 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 be performed by
personnel who has undergone special training or instructions or who is authorized
to work on explosion-protected devices in hazardous areas.

Safety instructions and measures
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 valve 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.
Sudden loud noise when the pneumatic actuator vents.
The positioner mounted onto the control valve can cause the pneumatic actuator to vent.
A loud noise may occur during venting. This can cause hearing damage.
ÎWear hearing protection when working near the valve.
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.
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.
