1 Safety instructions and measures
Intended use
SAMSON'sType3730-6Positionerismountedonpneumaticcontrolvalvesandis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speciedbySAMSON
Qualications of operating personnel
The positioner is to 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 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.

8 EB 8384-6 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.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. They 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 level, it must be restricted using a suitable supply pressure reducing station.
Explosion protection
−Explosive dust atmospheres of zone21 or zone22
ThefollowingappliestotypeofprotectionExiincombustibledustatmospheres:
Ifintrinsicsafetyisimpairedbytheinuenceofdust,anenclosurecomplyingwith
Clause6.1.3ofEN60079-11withatleastindegreeofprotectionIP5Xmustbeused.
TherequirementsaccordingtoClause6.1.3applytothecableglandsaccordingly.The
degreeofingressprotectionisveriedbyatestaccordingtoIEC60529andEN60079-
0(e.g.performedbyVDE).
For use in the presence of combustible dust in compliance with type of protection
ExtbIIIC(protectionbyenclosure),observeClause5.6.3ofEN60079-14.

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
according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 manufacturer performed a routine test on the device before putting it back into op-
eration. 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componentsby
the manufacturer.
Devices that have already been used outside hazardous areas and are intended for fu-
ture use inside hazardous areas must comply with the safety requirements placed on ser-
viced devices. Before being operated inside hazardous areas, test the devices according
tothespecicationsforservicingexplosion-protecteddevices.
EN60079-17appliestoservicingexplosion-protecteddevices.
−Maintenance, calibration and work on equipment
The protective cable designed by SAMSON must be used when interconnecting non-in-
trinsically safe set point calibrators with intrinsically safe equipment for repair, calibra-
tion, etc. to ensure that components relevant to explosion protection are not damaged.
Observethemaximumpermissiblevaluesspeciedinthecerticatesforintrinsicallysafe
circuits.
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.
