Safety instructions and measures
1 Safety instructions and measures
Intended use
SAMSON'sType3730-6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 other applications or con-
ditions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Type3730-6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 or operated only by trained and experienced
personnel familiar with the product. 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expe-
rience as well as their knowledge of the applicable standards.
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.

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.Anyhazardsthatcouldbecausedin
the valve by the process medium, the signal pressure or by moving parts are to be prevented
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.

Safety instructions and measures
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 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.
ÎReadthespecialinstructionsconcerningexplosionprotection(seesection1.4).
1.2 Notes on possible personal injury
WARNING
!
Crush hazard arising from moving parts on the valve.
Control valves contain moving parts (actuator and plug stem), which can injure hands or
ngersifinsertedintothevalve.
ÎDo not touch any moving valve parts while the control valve is in operation.
ÎBeforeperforminganymountingorinstallationworkonthepositioner,putthecontrol
valve out of operation by disconnecting and locking the supply air and control signal.
ÎDo not impede the movement of the actuator and plug stem by inserting objects into
the yoke.
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.
ÎDonotexceedthemaximumpermissiblevaluesspeciedintheECtypeexamination
certicateswheninterconnectingintrinsicallysafeelectricalequipment(UiorU0, lior
I0, Pior P0, Cior C0andLiorL0).
