Safety instructions and measures

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.
Î The following regulations apply to installation in hazardous areas: EN 60079-14(VDE 0165, Part 1).
Î Installation, operation or maintenance of the positioner must only be performed bypersonnel who has undergone special training or instructions or who is authorized
to work on explosion-protected devices in hazardous areas.

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 fingers is possible if they are inserted into thevalve.

Design and principle of operation

3 Design and principle of operation
Î See Fig. 3-1
The TROVIS 3730-3 Electropneumatic Positioner 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 theelectric control signal of a control system tothe travel or opening angle of the control
valve and issues a signal pressure for thepneumatic actuator.
The positioner mainly consists of a noncontact 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 pickup lever, 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 thetravel sensor (2) to the 4 to 20 mA DC
control signal issued by the control systemafter it has been converted by the A/D
converter (3).
In case of a set point deviation, the activation of the i/p module (7) is changed so thatthe actuator of the control valve (1) is pressurized or vented accordingly over thedownstream booster (6). As a result, the closure member of the valve (e.g. plug) is
moved to the position determined by the set
point.

EB 8484-3 EN

The positioner is operated by a rotary pushbutton (10) for menu navigation on theplain-text display (11).
The extended EXPERTplus diagnostics are integrated into the positioner. They provide information on the control valve and positioner
and generate diagnostic and status messages, which allow faults to be pinpointed
quickly.

3.1 Additional equipment
Volume restriction
The volume restriction Q serves to adapt the
air output capacity to the size of the actuator.
The volume restriction is a screw restriction
which is screwed into the signal pressure
output of the positioner (or output of thepressure gauge bracket or connecting plate).
Î We recommend using a volume restriction− 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 ofless than 300 cm³
Î Actuators with a transit time ≥ 1 s do not
require the air flow rate to be restricted.

3.1.1

Optional additional
functions

Note
Optional additional functions must be
selected at the ordering stage and are readyinstalled in the delivered positioner. The
options can only be exchanged or retrofitted
by SAMSON's After-sales Service.

the position transmitter allows positioner
faults to be indicated over a signal current of<2.4 mA or >21.6 mA.
Forced venting
The positioner either vents the actuator or
supplies it with air when the voltage signal at
the terminals falls below 11 V. This occurs
regardless of the set point. A voltage above
15 V keeps the forced venting function inactive.

Inductive limit contacts

Binary input

Inductive slot sensors issue a signal to a control system when the valve reaches one of thetwo adjustable limits. They are operated byadjustable tags. For operation of the inductive limit contacts, switching amplifiers must
be connected in the output circuit.

The binary input can be floating or
non-floating (0 to 24 V) and can be configured to provide the following functions:

Software limit contacts
The software limit contacts signalize that thevalve has reached one of the two adjustable
limits.
− When limit 1 is not reached− When limit 2 is exceeded
The following versions are available:− Connection of a PLC according toIEC 61131-2, Pmax = 400 mW− Connection to NAMUR switching amplifier acc. to EN 60947-5-6
Position transmitters
The position transmitter is a two-wire transmitter and issues the travel sensor signal as a
4 to 20 mA signal processed by the microcontroller. This signal is issued independentof the positioner’s input signal. Additionally,

EB 8484-3 EN− Switching state: the switching state of thebinary input is logged.
− On-site write protection: after the firstinitialization, a local write protection canbe activated. While the binary input isactive, no settings can be changed at thepositioner. The positioner cannot be
re-initialized.
− PST (partial stroke test): test to check thevalve's ability to move and assess its dynamic control response(PST: partial stroke test/FST: full stroketest).
− Start PST: perform a step response
test in an adjustable range.
− Start FST: perform a step response
test over the entire travel range following configurable parameters).
− Move valve to fixed value: move thevalve to a defined position (valve position in %).

3.3 Configuration using the
TROVIS-VIEW software
The positioner can be configured with
SAMSON's TROVIS-VIEW Software(version 4). For this purpose, the positioner
has a digital interface (SSP) to allow the USB
port of a computer to be connected to it
using an adapter cable.
The TROVIS-VIEW software enables the user
to easily configure the positioner as well asview process parameters online.
Note
TROVIS-VIEW provides a uniform user interface that allows users to configure and parameterize various SAMSON devices using
device-specific database modules. The
3730-3 device module can be downloaded
free of charge from our website atu www.samsongroup.com > SERVICE &SUPPORT > Downloads > TROVIS-VIEW.

Table 5-4 to Table 5-10 apply for attachingpositioners with stainless steel housings withthe following restrictions:
Direct attachment
All mounting kits from Table 5-5 and Table
5-6 can be used. The connection block is not
required. The stainless steel version of thepneumatic connecting plate routes the air internally to the actuator.
Attachment according to IEC 60534-6(NAMUR rib or attachment to rod-type
yokes)All mounting kits from Table 5-7 can beused. Connecting plate in stainless steel.

Attachment to rotary actuators
All mounting kits from Table 5-10 can beused except for the heavy-duty version. Connecting plate in stainless steel.

5.6.10 Air purging function for
single-acting actuators
The instrument air leaving the positioner isdiverted to the actuator spring chamber toprovide corrosion protection inside the actuator. Observe the following:
Direct attachment to Type 3277-5 (stem extends FA/stem retracts FE)
The air purging function is automaticallyprovided.
Direct attachment to Type 3277, 175 to
750 cm²
Stem extends: remove the stopper (12.2,
Fig. 5-9) at the black connection block andmake a pneumatic connection to the springchamber on the vented side.
Stem retracts: the air purging function is automatically provided.
Attachment according to IEC 60534-6(NAMUR rib or attachment to rod-type
yokes) and to rotary actuators
The positioner requires an additional port for
the exhaust air that can be connected overpiping. An adapter available as an accessory is used for this purpose:

EB 8484-3 EN

Installation

Note
The adapter uses one of the M20x1.5 connections in the housing which means only
one cable gland can be installed.
Should other valve accessories be usedwhich vent the actuator (e.g. solenoid valve,volume booster, quick exhaust valve), this exhaust air must also be included in the purging function. The connection over the adapter at the positioner must be protected with acheck valve (e.g. screw fitting with restriction
G ¼, order no. 1991-5777) or ¼ NPT (order no. 1992-3178) mounted in the piping.
Otherwise the pressure in the positioner
housing would rise above the ambient pressure and damage the positioner when theexhausting components respond suddenly.

5.7 Establishing pneumaticconnections! WARNING
Risk of injury by possible movement of
exposed parts (positioner, actuator or
valve) after connecting the signal pressure.
Î Do not touch or block exposed moving
parts.
! NOTICE
Incorrect connection of the supply air will
damage the positioner and will lead tomalfunction.
Î Screw the screw fittings into the connecting plate, pressure gauge mounting
block or connection block from the accessories.
The pneumatic ports are located on the backof the positioner (see Fig. 5-31).
! NOTICE

d = Seat diameter [cm]∆p = Differential pressure across thevalve [bar]A = Actuator area [cm²]F= Upper bench range value of theactuator [bar]If there are no specifications, calculate as
follows:
Î Required supply pressure = Upper benchrange value + 1 bar

Î See section 5.6.2 and Fig. 5-10.

5.7.4

Supply pressure

The required supply air pressure depends on
the bench range and the actuator's directionof action (fail-safe action).
The bench range is written on the nameplate
either as the bench range or signal pressure
range depending on the actuator. The direction of action is marked FA or FE or by a symbol.

Establishing HART®
communication

Communication between computer and positioner using an FSK modem or handheld
communicator (if necessary, using an isolation amplifier) is based on the HART® protocol.

Alternatively, a 250 Ω resistor can be connected in series and a 22 μF capacitor canbe connected in parallel to the analog output
of positioners without explosion protection
and positioners with type of protection Ex tb(Fig. 5-40). The load for the controller output
will increase as a result.

If the load impedance of the controller orcontrol station is too low, an isolation amplifier must be connected between controller
and positioner (interfacing as for positioner
connected in hazardous areas). See
Fig. 5-39.
If the positioner is used in hazardous areas,an explosion-protected isolation amplifiermust be used.
Using the HART® protocol, all connected
control room and field units can be addressed individually with their address using
a standard bus.
Standard bus:
In the standard bus mode, the positioner follows the analog set point. The bus address/
polling address has to be within a range of
1 to 15.
When communication errors occur:
Communication errors may occur when theprocess controller/control station output is
not HART®-compatible.

Start-up and configuration

7.4.5

Selecting the initialization mode

During initialization the positioner adapts itself optimally to the friction conditions and the signal
pressure required by the control valve. The type and extent of autotuning depends on the initialization mode selected. The following initialization modes are available:
MAX: Maximum range
The positioner determines travel/angle of rotation of the closing member from the CLOSED
position to the opposite travel stop and adopts this travel/angle of rotation as the operating
range from 0 to 100 %.
NOM: Nominal range · Initialization mode for all globe valves
The calibrated sensor allows the exact valve travel to be measured very accurately. Duringinitialization, the positioner checks whether the control valve can move through the indicatednominal range (travel or angle) without collision. If this is the case, the indicated nominal
range is adopted as the operating range.
MAN: Manually selected end positions · Initialization mode for globe valves
Before starting initialization, move the control valve manually to the end positions. The positioner calculates the travel/angle difference from the two positions that the valve moved toand adopts it as the operating range. This initialization mode can only be started when thevalve position differs in the end positions and the positioner has not yet been initialized.
SUB: Substitute calibration · To replace a positioner while the plant is running
A complete initialization procedure takes several minutes and requires the valve to movethrough its entire travel range several times. In the SUB initialization mode, the control parameters are estimated and not determined by an initialization procedure. As a result, a highlevel of accuracy cannot be expected. A different initialization mode should be selected if theplant allows it.
The substitute calibration is used to replace a positioner while the process is running. For thispurpose, the control valve is usually blocked mechanically in a certain position or pneumatically by means of a pressure signal which is routed to the actuator externally. The blocking
position ensures that the plant continues to operate with this valve position. The blocking position can also be the fail-safe position when this condition is beneficial for the temporary
phase.
Perform a reset before re-initializing the positioner if the substitute positioner has alreadybeen initialized (see the 'Operation' section).

Description of Equipment:
General - The Type TROVIS 3730-3 HART Positioner is a single acting positioner for attachment to pneumatic
control valves. The positioner ensures a predetermined assignment of the valve position (controlled variablex) to the input signal (reference variable w). It compares the input signal received from a control system to thetravel or rotational angle of the control valve and issues a corresponding output signal pressure (output variabley) for the pneumatic actuator.
Construction - The Type TROVIS 3730-3 HART Positioner mainly consists of the electronics part and one
pneumatic module. The parts are assembled in an enclosure made of aluminium die cast or stainless-steel die
cast. The enclosure has a cover with a polymeric inspection window. As an alternative to the polymeric material
the window can be made from aluminium. The enclosure has an ingress protection rating ofType 4X and IP66

Description of Equipment or Protective System:
Type 3725
General - The type 3725 electropneumatic positioner is a single-acting positioner for attachment topneumatic linear and rotary valves. It is a self-calibrating device with automatic adaptation to valve andactuator. The positioner is mounted on pneumatic control valves and is used to assign the valve position(controlled variable x) to the control signal (reference variable w). The positioner compares the electric
control signal of a control system to the travel or rotational angle of the control valve and issues a signal
pressure (output variable y) for the pneumatic actuator.
The positioner consists of a magneto resistive sensor (2), an analog i/p converter (6) with a downstream
booster (7) and the electronics unit with microcontroller (4). The travel or opening angle is measured by the
pick-up lever connected to the sensor (2) installed in the positioner and the downstream electronics. Whena system deviation occurs, the actuator is either vented or filled with air. If necessary, the signal pressurechange can be slowed down by a volume restriction as necessary. The i/p module (6) is supplied with aconstant upstream pressure by the pressure
regulator (8) to make it independent of the supply air pressure.
Construction - The Type 3725 electropneumatic positioner mainly consists of the electronics part. The
parts are assembled in an enclosure made of aluminium die cast or stainless-steel die cast. The enclosure
has a cover with a polymeric inspection window. As an alternative to the polymeric material, the window
can be made from aluminium. The enclosure has an ingress protection rating of IP66
See Annex for model code, thermal and electrical values.
TROVIS 3730-1
General – The TROVIS 3730-1 Positioner is a single acting positioner for attachment to pneumatic control
valves. The positioner mainly consists of a non-contact travel sensor system, an i/p converter and theelectronics with the microcontroller. The valve position is transmitted either as an angle of rotation or a
travel to the pick-up lever, from there to the travel sensor and forwarded to the microcontroller. The PID
algorithm in the microcontroller compares the valve position measured by the travel sensor to the 4 to 20
mA DC control signal issued by the control system after it has been converted by the AD converter. In caseof a set point deviation, the i/p converter causes the actuator to be either vented or filled with air. As aresult, the closure member of the valve is moved to the position determined by the reference variable. The
pneumatic module is supplied with supply air and the flow rate of the module’s output can be restricted bysoftwareConstruction - The Type TROVIS 3730-1 HART° Positioner mainly consists of the electronics part. The
parts are assembled in an enclosure made of aluminium die cast or stainless-steel die cast. The enclosure
has a cover with a polymeric inspection window. As an alternative to the polymeric material, the window
can be made from aluminium. The enclosure has an ingress protection rating of IP66
See Annex for model code, thermal and electrical values.
TROVIS 3730-3
General - The Type TROVIS 3730-3 HART® Positioner is a single acting positioner for attachment topneumatic control valves. The positioner ensures a predetermined assignment of the valve position(controlled variable x) to the input signal (reference variable w). It compares the input signal received froma control system to the travel or rotational angle of the control valve and issues a corresponding output
signal pressure (output variable y) for the pneumatic actuator.
Construction - The Type TROVIS 3730-3 HART° Positioner mainly consists of the electronics part andone pneumatic module. The parts are assembled in an enclosure made of aluminium die cast or stainlessTHIS CERTIFICATE MAY ONLY BE REPRODUCED IN ITS ENTIRETY AND WITHOUT CHANGE

3730-4/5
General - The positioners type 3730-41, 3730-51, 3730-45 and 3730-55 are communication-capable, buspowered field devices which are used to assign a valve position to a control signal. The bus interface
connection (bus-coupling) can be performed according to the FISCO-concept for both specifications,
Profibus PA and FoundationTM Fieldbus. They are mounted onto levitation and slewing actuators. Nonflammable media are used as pneumatic auxiliary power. The equipment is intended for the application
inside the hazardous area.
The positioners type 3730-48 and 3730-58 are communication-capable, bus powered field devices which
are used to assign a valve position to a control signal. They are mounted onto levitation and slewing
actuators. Non-flammable media are used as pneumatic auxiliary power. The equipment is intended forthe application inside the hazardous area.
Construction - The Type TROVIS 3730-4_5 HART° Positioner mainly consists of the electronics part. The
parts are assembled in an enclosure made of aluminium die cast or stainless-steel die cast. The enclosure
has a cover with a polymeric inspection window. As an alternative to the polymeric material, the window
can be made from aluminium. The enclosure has an ingress protection rating of IP66
See Annex for model code, thermal and electrical values.
TROVIS 3793
General - The Type 3793 HART Positioner is a single or double acting positioner for attachment topneumatic control valves. The positioner ensures a pre-determined assignment of the valve position to the
input signal. It compares the input signal received from a control system to the travel or rotational angle ofthe control value and issues a corresponding output signal pressure for the pneumatic actuator
Construction - The 3793 HART Transmitter Positioner consists of the electronic part and one or two
pneumatic modules. The parts are assembled in an enclosure made of aluminium die cast or stainlesssteel die cast. The enclosure has a cover with a polymeric inspection window. As an alternative to thepolymeric material the window can be made from aluminium. The enclosure has an ingress protection

Description of Equipment or Protective System:TROVIS 3730-1
General – The TROVIS 3730-1 Positioner is a single acting positioner for attachment to pneumatic
control valves. The positioner mainly consists of a non-contact travel sensor system, an i/p converter
and the electronics with the microcontroller. The valve position is transmitted either as an angle ofrotation or a travel to the pick-up lever, from there to the travel sensor and forwarded to themicrocontroller. The PID algorithm in the microcontroller compares the valve position measured by thetravel sensor to the 4 to 20 mA DC control signal issued by the control system after it has been converted
by the AD converter. In case of a set point deviation, the i/p converter causes the actuator to be either
vented or filled with air. As a result, the closure member of the valve is moved to the position determinedby the reference variable. The pneumatic module is supplied with supply air and the flow rate of themodule’s output can be restricted by software
Construction - The Type TROVIS 3730-1 Positioner mainly consists of the electronics part. The parts
are assembled in an enclosure made of aluminium die cast or stainless-steel die cast. The enclosure
has a cover with a polymeric inspection window. As an alternative to the polymeric material, the window
can be made from aluminium. The enclosure has an ingress protection rating of IP66
See Annex for model code, thermal and electrical values.
TROVIS 3730-3
General - The Type TROVIS 3730-3 HART Positioner is a single acting positioner for attachment topneumatic control valves. The positioner ensures a predetermined assignment of the valve position(controlled variable x) to the input signal (reference variable w). It compares the input signal received
from a control system to the travel or rotational angle of the control valve and issues a corresponding
output signal pressure (output variable y) for the pneumatic actuator.
Construction - The Type TROVIS 3730-3 HART Positioner mainly consists of the electronics part andone pneumatic module. The parts are assembled in an enclosure made of aluminium die cast or stainlesssteel die cast. The enclosure has a cover with a polymeric inspection window. As an alternative to thepolymeric material the window can be made from aluminium. The enclosure has an ingress protection
rating of IP66
See Annex for model code, thermal and electrical values.
3730-4/5
General - The positioners type 3730-41, 3730-51, 3730-45 and 3730-55 are communication-capable,
bus-powered field devices which are used to assign a valve position to a control signal. The bus interface
connection (bus-coupling) can be performed according to the FISCO-concept for both specifications,
Profibus PA and FoundationTM Fieldbus. They are mounted onto levitation and slewing actuators. Nonflammable media are used as pneumatic auxiliary power. The equipment is intended for the application
inside the hazardous area.
The positioners type 3730-48 and 3730-58 are communication-capable, bus powered field devices which
are used to assign a valve position to a control signal. They are mounted onto levitation and slewing
actuators. Non-flammable media are used as pneumatic auxiliary power. The equipment is intended forthe application inside the hazardous area.
Construction - The Type 3730-4/5 Positioner mainly consists of the electronics part. The parts areassembled in an enclosure made of aluminium die cast or stainless-steel die cast. The enclosure has acover with a polymeric inspection window. As an alternative to the polymeric material, the window canbe made from aluminium. The enclosure has an ingress protection rating of Type 4X and IP66

Set point processing

8.1

Lower w-range value

8.1.1[0.0] to 75.0 %The lower set point range value must be lower than upper
range value (w-end), 0 % = 4 mA.
The set point range is the difference between w-end andw-start and must be Δw ≥ 25 % = 4 mA.
When the set point range of 0 to 100 % = 4 to 20 mA, thevalve must move through its entire operating range from 0 to
100 % travel/angle of rotation.
In split-range operation, the valves operate with smaller set
points. The control signal of the control unit to control twovalves is divided such, for instance, that the valves movethrough their full travel/angle of rotation at only half the input
signal (first valve set to 0 to 50 % = 4 to 12 mA and second
valve set to 50 to 100 % =12 to 20 mA).

Adjustment range/values [default setting]/description

Lower x-range value

8.1.5[0.0] to 99.0 %Lower range value for travel/angle in nominal or operating
range
The operating range is the actual travel/angle of the valve andis limited by the lower travel/angle range value and the upper
travel/angle range value. Usually, the operating range and thenominal range are identical. The nominal range can be limited
to the operating range by the lower and upper x-range values.
The value is displayed or must be entered. The characteristic is
adapted. The difference between the lower and upper x-range
values must be at least 1 %.

Upper x-range value

8.1.6

1.0 to [100.0 %]Upper range value for travel/angle in nominal or operating
range
The value is displayed or must be entered.
The characteristic is adapted.
Example: The operating range is modified, for example to limit
the range of a control valve which has been sized too large.
For this function, the entire resolution range of the set point isconverted to the new limits.
0 % on the display corresponds to the adjusted lower limit and
100 % to the adjusted upper limit.
The difference between the lower and upper x-range values
must be at least 1 %.

Ramp time (rising)

8.1.7[0.0] to 10000.0 s
Time required to move through the operating range when thevalve opens.
For some applications it is recommendable to limit the transit
time of the actuator to prevent it from engaging too fast in therunning process.

Ramp time (falling)
