Intended use
TheSAMSONTROVIS3730-1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.

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

Design and principle of operation
3 Design and principle of oper-
ation
ÎSeeFig.3-1
TheTROVIS3730-1ElectropneumaticPosi-
tioner is mounted on pneumatic control
valves and used to assign the valve position
(controlled variable x) to the control signal
(set point w). The positioner compares the
electric control signal of a control system to
the travel or opening angle of the control
valve and issues a signal pressure for the
pneumatic actuator.
The positioner mainly consists of a non-con-
tact travel sensor system (2), pneumatics and
the electronics with the microcontroller (4).
The valve position is transmitted either as an
angle of rotation or a travel to the pick-up le-
ver, from there to the travel sensor (2) and
forwarded to the microcontroller (4). The PID
algorithm in the microcontroller compares
the valve position measured by the travel
sensor(2)tothe4to20mADCcontrolsig-
nal issued by the control system after it has
beenconvertedbytheA/Dconverter(3).
In case of a set point deviation, the activa-
tionofthei/pmodule(7)ischangedsothat
the actuator of the control valve (1) is pres-
surized or vented accordingly over the
downstream booster (6). As a result, the clo-
sure member of the valve (e.g. plug) is
moved to the position determined by the set
point.
The positioner is operated by a rotary push-
button (9) for menu navigation on the dis-
play (11).
3.1 Additional equipment
Volume restriction
The volume restriction Q serves to adapt the
air output capacity to the size of the actua-
tor.
The volume restriction is a screw restriction
which is screwed into the signal pressure
output of the positioner (or output of the
pressure gauge bracket or connecting plate).
ÎWe recommend using a volume restric-
tion:
− For linear actuators with a transit
time<1s(e.g.withanactuatorarea
smallerthan240cm²)
− For rotary actuators with a volume of
lessthan300cm³.
ÎActuatorswithatransittime≥1sdonot
requiretheairowratetoberestricted.
3.1.1 Options
The optional additional functions of the
TROVIS3730-1Positionerallowsittobe
adaptedtospecicrequirements.
Inductive limit contacts
Limit contacts with mechanical position pick-
up issue a signal to a control system when
the valve reaches one of the two adjustable
limits.
Inductive proximity switches are operated by
adjustable tags. For operation of the induc-
tivelimitcontacts,switchingampliersmust
be connected in the output circuit.
