3.1 Additional equipment

Î See Fig. 3-1

The volume restriction Q serves to adapt the
air output capacity to the size of the actuator.

The TROVIS 3730-1 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 linear travel to thepick-up 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.
The positioner is operated by a rotary pushbutton (9) for menu navigation on the display (11).

EB 8484-1 EN

Volume restriction

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

Options

The optional additional functions of the
TROVIS 3730-1 Positioner allows it to beadapted to specific requirements.
Inductive limit switches
Limit contacts with mechanical position pickup issue a signal to a control system whenthe valve reaches one of the two adjustable
limits.
Inductive proximity switches are operated byadjustable tags. For operation of the inductive limit contacts, switching amplifiers must
be connected in the output circuit.

5.6.7

Reversing amplifier for
double-acting actuators

For the use with double-acting actuators, thepositioner must be fitted with a reversing amplifier:Î SAMSON Type 3710 Reversing Amplifier,u EB 8392
The following applies to all reversing
amplifiers:
The signal pressure of the positioner is supplied at the output 1 of the reversing amplifier. An opposing pressure, which equals therequired supply pressure (Z) when added tothe pressure at output 1, is applied at output
2.
The following relationship applies:
output 1 + output 2 = Supply pressure (Z).
Connect output 1 to the signal pressure connection on the actuator that causes the valve
to open when the pressure rises.
Connect output 2 to the signal pressure connection on the actuator that causes the valve
to close when the pressure rises.

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 (stemextends 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:
Threaded bushing G ¼
0310-2619(M20x1.5)¼ NPT 0310-2550

Note
The adapter uses one of the M20x1.5 connections in the housing which means only
one cable gland can be installed.

5-31Installation

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.

! NOTICE
Risk of malfunction due to failure to comply
with air quality requirements.
Î Only use supply air that is dry and freeof oil and dust.

Start-up and configuration

Tip
For normal operation, simply start initialization over Code P22 after mounting the positioner
on the valve, checking the fail-safe position (P3), to ensure that the positioner works properly. The positioner only works with its default settings.
The type and extent of self-adaptation depends on the preset parameters. MAX applies as
the default setting for the nominal range (Code P5). During the initialization process, the positioner determines the total travel range or rotational range of the valve (from the CLOSED
position to the opposite end position).
Start initialization:
Î Enable configuration (Chapter 7.1).
1. Turn

until Code P22 appears.

2. Pressand hold for 3 s (reading: 3 ... 2 ... 1).

Î Initialization starts. P22 and INIT blink during initialization. The
time required for the initialization procedure depends on the actuator transit time, which means that initialization can take a few
minutes.

Malfunctions

Example:If, for instance, a travel has been entered in Code P5 (nominal range), which is larger thanthe maximum valve travel possible, the rated travel cannot be reached during initialization
process. In this case, initialization is canceled. Closed-loop operation is continued if the positioner has already been initialized. When the positioner has not yet been initialized, thevalve returns to the fail-safe position (indicated by the S icon). After Code P0 or P27 the error codes E2 (positioner not initialized) and E6 (rated travel not reached) are displayed.

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
case of 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 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 can bemade from aluminium. The enclosure has an ingress protection rating of Type 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.

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, 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,

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

TROVIS / TROVIS SAFE 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 of the 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
rating of IP66
