1 Safety instructions and measures

Intended use

TheSAMSONType3730-0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 exact-

ly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3730-0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.

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.

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.

−Maintenance, calibration and work on equipment

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circuit.

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

1.2 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.

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inpage26.

An incorrect electrical power supply 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.

EB 8384-0 EN 9

Safety instructions and measures

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.

Design and principle of operation

3 Design and principle of oper-

ation

ÎRefertoFig.1

The electropneumatic positioner is mounted

on pneumatic control valves and is used to

assign the valve position (controlled variable

x) to the control signal (set point w). The po-

sitioner compares the electric control signal

of a control system to the travel of the control

valve and issues a signal pressure (output

variabley)forthepneumaticactuator.

Asupplypressurebetween1.4to6baris

required. The electric input signal is a set

pointbetween4to20mA.

The positioner is designed depending on

which accessories are selected either for

directattachmenttoSAMSONType3277

Actuators or for attachment to actuators

accordingtoNAMUR(IEC60534-6).

The positioner consists of a travel sensor

system proportional to resistance, an analog

i/p converter with a downstream air

capacity booster and the electronics with

microcontroller.

Fig.1: Functional diagram

EB 8384-0 EN 13

Design and principle of operation

The position of the valve stem is transmitted

as a linear travel motion over the pick-up le-

ver to the travel sensor (2) and supplied to

an analog PD controller (3). The PD control-

ler compares this actual value to the DC con-

trol signal coming from the control system,

e.g.a4to20mAsignal.

In case of a system deviation, the activation

of the i/p module (6) is changed so that the

actuator of the control valve (1) is pressur-

ized or vented accordingly over the down-

stream booster (7). This causes the valve

plug to move to the position determined by

the set point.

The supply air is supplied to the booster (7)

and the pressure regulator (8). An intermedi-

ateowregulator(9)withxedsettingsis

used to purge the positioner and, at the

same time, guarantees trouble-free operation

of the booster. The output signal pressure

supplied by the booster can be limited by

enabling the DIP switch setting S5.

The volume restriction (10) and the switch S6

are used to optimize the positioner by

adapting it to the actuator size and chang-

ing the gain factor.

Tight-closing function:

After activating the tight-closing function (see

section 7.4), the pneumatic actuator is com-

pletelylledwithairorventedassoonas

the set point falls below or exceeds the corre-

spondingdeactivatingpointof4.5mAor

19.5mA.

In the case of three-way valves, the function

allows the plug move to the end position

with full actuator thrust.

3.1 Mounting versions

TheType3730-0Positionerissuitableforthe

following types of attachment using the cor-

respondingaccessories(seesection3.3):

−DirectattachmenttoType3277Actuator

(seesection5.3):Thepositioneris

tends" fail-safe action and through an

external signal pressure line for "actuator

stem retracts" fail-safe action.

−Attachment to actuators according to
