er with a downstream air booster and theelectronics with the microcontroller.
When a system deviation occurs, the actuator is either vented or filled with air. If necessary, the signal pressure change can be
slowed down by a volume restriction. The
signal pressure supplied to the actuator canbe limited by software or on site to 1.4, 2.4
or 3.7 bar.

Î See Fig. 3-1
The 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
the control signal of a control system to thetravel or rotational angle of the control valve
and issues a signal pressure (output variable y) for the pneumatic actuator.

The fixed flow regulator ensures a constant
air flow to the atmosphere, which is used toflush the inside of the positioner housing andto optimize the air booster. The i/p converter
is supplied with a constant upstream pres-

The positioner mainly consists of an electric

sure by the pressure regulator to compensate
for any fluctuations in the supply pressure.
The positioner communicates and is poweredusing IEC 61158-2 transmission technology
conforming to PROFIBUS-PA specifications.
As a standard feature, the positioner comeswith a binary input for DC voltage signals tosignalize process information over the
PROFIBUS-PA network.
The extended EXPERTplus diagnostics are integrated into the positioner. They provide information on the positioner and generate diagnostic and status messages, which allow
faults to be pinpointed quickly.

3.1 Mounting versions
The positioner is suitable for the following
types of attachment using the corresponding
accessories:− Direct attachment to SAMSONType 3277 Actuator− Attachment to actuators according toIEC 60534-6− Attachment according to VDI/
VDE 3847-1/-2− Attachment to Type 3510 Micro-flow
Valve− Attachment to rotary actuators according
to VDI/VDE 3845

3.2 Additional equipment
Solenoid valve
If the voltage supply for the solenoid valve(12) fails, the supply pressure for the i/p

3-2

converter is vented to the atmosphere. The
positioner can no longer operate and thecontrol valve moves to the fail-safe position
determined by the actuator, regardless of theset point.
! NOTICE
The manual set point is also reset to 0 % after the solenoid valve is activated.
A different manual set point must be enteredagain (Code 1).
Inductive limit switch
In this version, the rotary shaft of the positioner carries an adjustable tag which actuates the built-in proximity switch.
External position sensor
In this version, only the sensor is mounted tothe control valve. The positioner is locatedseparately from the valve. The connection ofx and y signals to the valve is established bycable and piping for air (only without inductive limit switch).
Binary input BI1
As a standard feature, the positioner comeswith a binary input for DC voltage signals tosignalize process information over the
PROFIBUS-PA network.
Binary input BI2
This binary input BI2 is optional. It is an active input which is powered by the positioner
to connect a floating contact. The switchingstate of the floating contact can be indicatedover the PROFIBUS-PA network.

Design and principle of operation

3.3 Communication
The positioner is controlled completely bydigital signal transmission according to
PROFIBUS-PA profile class B according to
DIN EN 50170 and DIN 19245-4.
Data are transmitted over the bus using digital, bit-synchronous Manchester coding at a
Baud rate of 31.25 kbit/s over twisted-pairwires according to IEC 61158-2.
Usually, the positioner settings are made on
a computer. One or more positioners can beconnected over a segment coupler to the
PROFIBUS segment of the computer.

Reversing amplifier for
double-acting actuators

For the use with double-acting actuators, thepositioner must be fitted with a reversing amplifier, e.g. the SAMSON Type 3710 Reversing Amplifier (see Mounting and Operating Instructions 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.
Î Set slide switch on positioner to AIR TO
OPEN.
Note
How the outputs are marked depends on thereversing amplifier used. Type 3710: Output
1/2 = Y1/Y2

the exhaust air that can be connected overpiping. An adapter available as an accessory is used for this purpose:
Threaded bushing (M20x1.5)

G¼
¼ NPT

0310-2619
0310-2550

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. check valve G ¼, order no.
8502-0597) mounted in the piping. Otherwise the pressure in the positioner housing
would rise above the ambient pressure anddamage the positioner when the exhausting
components respond suddenly.

5.11.1 Signal pressure connection
The signal pressure connection depends on
how the positioner is mounted onto the actuator:

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.
Actuator stem extends FA (AIR TO OPEN)

Type 3277 Actuator

Fail-close (for globe and angle valves):− The signal pressure connection is fixed.

Î Required supply pressure = Upper benchrange value + 0.2 bar, at least 1.4 bar.

Attachment according to IEC 60534-6(NAMUR)− For "actuator stem retracts" fail-safe action: connect the signal pressure to theconnection on top of the actuator.
− For "actuator stem extends" fail-safe action: connect the signal pressure to theconnection on bottom of the actuator.
Rotary actuators− For rotary actuators, the manufacturer's
specifications for connection apply.

5.11.2 Signal pressure reading

Actuator stem retracts FE (AIR TO CLOSE)
Fail-open (for globe and angle valves):
For tight-closing valves, the maximum signal
pressure pstmax is roughly estimated as follows:
pstmax = F +d² · π · ∆p
4·A

[bar]

d = Seat diameter [cm]∆p = Differential pressure across the valve[bar]
A = Actuator area [cm²]F= Upper bench range value of the actuator
[bar]

Tip
To monitor the supply air and signal pressure, we recommend mounting pressuregauges (see accessories in section 5.13).

If there are no specifications, calculate as
follows:

Bus line

Limit switch

Route the two-wire bus line to the screw terminals marked "IEC 1158-2", whereby nopolarity needs to be observed.
To connect the limit switch, binary inputs andsolenoid valve, an additional cable gland thatneeds to be fitted in place of the existingblanking plug is necessary.

The operation of the limit switch requires aswitching amplifier to be connected in the
output circuit. Its function is to control the limit values of the control circuit according to
EN 60947-5-6, thus ensuring operationalreliability of the positioner.
Observe the relevant regulations for installation in hazardous areas.
Binary input BI1! NOTICE
Degree of protection may be impaired.
Î Seal cable glands left unused with blanking plugs.

EN 60947-5-6

5.12.2 Establishing communication
The communication structure between thecontroller, logic solvers (PLC) or automation
system or between a computer or work station and the positioner(s) is implemented using a segment coupler (see Fig. 5-32) according to the PROFIBUS guidelines.
Explosion-protected versions of PROFIBUS-PA segment couplers must be used inhazardous areas.
A maximum of 32 positioners can be operated in parallel over a segment coupler in
one PROFIBUS-PA segment. In hazardous
areas, the number of positioners that can beconnected is reduced.
Each positioner connected in the segment
must be assigned a unique bus address between 0 and 125 (see the 'Start-up and configuration' section).

For operation of the limit switches, switching
amplifiers must be connected in the output
circuit. They must comply with the limit values of the output circuits conforming to
EN 60947-5-6.
Î Observe the relevant regulations for installation in hazardous areas.
For applications in safe areas (non-hazardous areas), limit switches can be directly interconnected to the binary input of the PLC in
accordance with IEC 61131. This applies tothe standard operating range for digital inputs according to Clause 5.2.1.2 of
IEC 61131-2 with the rated voltage of
24 V DC.

Reading after connecting the electrical power supply:
After tEStinG runs across the display, the fault alarm icon appears
and the hand icon blinks on the display when the positioner has
not been initialized. The reading indicates the lever position in degrees in relation to the mid-axis.
Code 0 is displayed when a positioner has been initialized. The positioner is in the last active operating mode.
The positioner performs a test in the start-up phase while following its automation task at thesame time.
During the start-up phase, operation on site is unrestricted, yet write access is limited.

For checking purposes: after successfully completing initialization, the positioner display
must read 0 % when the valve is closed and 100 % when the valve is open. If this is not thecase, change the slide switch position and re-initialize the positioner.
Note
The switch position is prompted prior to an initialization. After an initialization has been
completed, changing the switch position does not have any effect on the operation of the positioner.

Risk of injury due to the actuator stem extending or retracting.
Î Before exchanging the lever or changing the pin position, disconnect the supply air andelectrical auxiliary power.

7.5 Initializing the positioner! WARNING
Risk of injury by exposed moving parts on the positioner, actuator or valve.
Î Do not touch or block exposed moving parts.
! NOTICE
The process is disturbed by the movement of the actuator or valve.
Î Do not perform the initialization while the process is running. First isolate the plant byclosing the shut-off valves.
Î Check the max. permissible signal pressure of the valve before starting initialization.
During initialization, the positioner issues an output signal pressure up to the maximum
supply pressure supplied. If necessary, limit the signal pressure by connecting an upstream pressure reducing valve.
Note
Reset positioner to its default settings (see the 'Operation' section) before mounting it on adifferent actuator or changing its mounting position.
During initialization, the positioner adapts itself optimally to the friction conditions and thesignal pressure required by the control valve. The type and extent of auto tuning depends on
the initialization mode selected:− Maximum range (MAX) (standard range)
Initialization mode for simple start-up of valves with two clearly defined mechanical end
positions, e.g. three-way valves (see section 7.5.1)− Nominal range (NOM)

SUb – Substitute calibration

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 fixed mechanically in a certain position or pneumatically

The positioner can either be start up, configured and operated on site, using the fieldbus configuration or operating system or TROVIS-VIEW user interface connected over the serial interface in the positioner. Use the TROVIS-VIEW software with 3730-4 device module installed.
To connect the positioner directly to the computer via the local serial interface, an adapter(order no. 1400-9740) is required.
The power supply for the positioner can be supplied either over the connection to the fieldbus
segment or over a DC voltage source (9 to 32 V) connected to the bus terminals in the positioner (a suitable intrinsically safe source must be used inside and outside the hazardous area for intrinsically safe positioners). The simultaneous operation of TROVIS-VIEW and thefieldbus system is possible without any restrictions when connected to a PROFIBUS-PA segment.

Note
The bus address can only be implemented by the PROFIBUS command SET_ADDRESS when
the bus address is set to the default setting [126]. Refer to Configuration Manualu KH 8384-4.

7.9 Adjusting inductive limit switch
The positioner version with an inductive limit switch has an adjustable tag (1) mounted on theaxis of rotation, which operates the proximity switch (3).
For operation of the inductive limit switch, the corresponding switching amplifier (see the 'Installation' section) must be connected to the output circuit.
When the tag (1) is located in the inductive field of the switch, the switch assumes a high resistance. When it moves outside the field, the switch assumes a low resistance.
Normally, the limit switch is adjusted in such a way that it will provide a signal in both end
positions of the valve. The switch, however, can also be adjusted to indicate intermediate
valve positions.
The required switching function, i.e. whether the output relay is to be picked up or released
when the tag enters the field, must be selected at the switching amplifier, if required.

EB 8384-4 EN

Adjusting the switching point
Note
During adjustment or testing, the switching point must always be approached from mid-position (50 %).
To guarantee the switching under all ambient conditions, adjust the switching point approx.
5 % before the mechanical stop (OPEN – CLOSED).
For CLOSED position:
1. Initialize the positioner.
2. Move the valve to 5 % in the MAN mode (see display).
3. Adjust the tag at the yellow adjustment screw (2) until the tag enters or leaves the field

9 Malfunctions
Malfunctions are indicated on the display
by error codes. Annex A lists possible error
messages and recommended action.
The error codes appear on the display corresponding to their status classification set overthe condensed state (Maintenance required/
Maintenance demanded: , Maintenancealarm: ). If 'No message' is assigned to theerror code as the status classification, the error is not included in the condensed state.
A status classification is assigned to every error code in the default setting. The assignment of the status classification can bechanged in TROVIS-VIEW and over the
PROFIBUS-PA parameters. Refer to the Operating Instructions for the EXPERTplus valve
diagnostics u EB 8389 and the Configuration Manual u KH 8384-4 for more details.
To provide a better overview, the classified
messages are summarized in a condensed
state for the positioner according to the
NAMUR Recommendation NE 107. The status messages are divided into the following
categories:− Maintenance alarm
The positioner cannot perform its control
task due to a malfunction in the positioner itself or in one of its peripherals or the
positioner has not yet been successfully
initialized.
− Maintenance required
The positioner still performs its control
task (with restrictions). A maintenancedemand or above average wear has
been determined. The wear tolerance will

EB 8384-4 ENsoon be exhausted or is reducing at afaster rate than expected. Maintenance isnecessary in the medium term.
− Maintenance demanded
The positioner still performs its control
task (with restrictions). A maintenancedemand or above average wear has
been determined. The wear tolerance willsoon be exhausted or is reducing at afaster rate than expected. Maintenance isnecessary in the short term.
− Process-related malfunction/out of specification
The device is running outside the specified operating conditions..
− Function check
Test or calibration procedures are performed in the positioner. The positioner is
temporarily unable to perform its control
task as long as the procedure is taking
place.
If an event is classified as “No message”, thisevent does not have any affect on the condensed state.

EB 8384-4 ENMalfunctions

9.2 Emergency action
Fail-safe action is triggered by the i/p converter or solenoid valve and upon supply air
failure. The positioner fully discharges its
pneumatic output to the atmosphere, causing
the pneumatic actuator to be vented. As aresult, the valve moves to the fail-safe position. The fail-safe position depends on how
the springs are arranged in the pneumatic
actuator (air-to-close or air-to-open).

Tip
Emergency action in the event of valve or actuator failure is described in the associatedvalve and actuator documentation.
Î Plant operators are responsible for emergency action to be taken in the plant.

When the supply air fails, the optional solenoid valve or forced venting is triggered andafter reaching the shutdown signal, all positioner functions, except open/closed loop
control, remain active (including diagnostics
as well as position and status feedback).

Description
If the set point w reaches up to the entered percentage at the final
value that causes the valve to open, the actuator is immediately filledwith air (with AIR TO OPEN) or completely vented (with AIR TO
CLOSE). This action always leads to the valve being completely
opened. The signal pressure can be limited in Code 16.

initialization, the values for KP and TV are optimally set.
If the positioner tends to overshoot impermissibly due to otherdisturbances, the KP and TV levels can be adapted accordingly after
initialization. Increment TV level until desired behavior is reached orwhen the maximum value of 4 is reached, the KP level can be
decreased in increments.
KP level changes affect the set point deviation.

No emergency mode The travel measuring system of the positioner has a self-monitoring
function (see Code 62).
An emergency mode (open-loop control) is not available for certain
actuators, such as double-acting actuators. In case of a travel sensing
error, the positioner vents the output (Output 38) or A1 in double-acting
actuators. During the initialization, the positioner automatically checks
whether the actuator has such a function or not.
