3 Design and principle of operation
Î Refer to Fig. 1
The electropneumatic positioner is mounted
on pneumatic control valves and is used toassign the valve position (controlled variable x) to the control signal (set point w). The
electric signal from a controlling system iscompared to the travel or the rotational angleof the control valve and a signal pressure(output variable y) is produced for the actuator.
The positioner consists of a travel sensor
system (2) proportional to resistance, ananalog i/p converter with a downstream air
capacity booster (7) and the electronics withmicrocontroller (5).
The positioner is fitted with three binary
contacts as standard: A fault alarm output
indicates a fault to the control room and two
configurable software limit switches are used
to indicate the end positions of the valve.

Design and principle of operation

The valve position is transmitted as a either
an angle of rotation or travel to the pick-up
lever and to the travel sensor (2) and supplied
to an analog PD controller. An A/D converter(4) transmits the position of the valve to themicrocontroller (5). The PD controller compares this actual position to the 4 to 20 mA
DC control signal (reference variable) after it
has been converted by the A/D converter (4).
In case of a set point deviation, the activationof the i/p converter (6) is changed so that theactuator of the control valve (1) is pressurized
or vented accordingly over the downstream
booster (7). As a result, the closure memberof the valve (e.g. plug) is moved to the position determined by the set point.
The supply air is supplied to the booster (7)and the pressure regulator (8). An intermediate flow regulator (9) with fixed settings isused to purge the positioner and, at the sametime, guarantees trouble-free operation of thebooster. The output signal pressure suppliedby the booster can be limited by software.
The volume restriction Q (10) is used to optimize the positioner.
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 (see section 3.4):

20− Direct attachment to SAMSONType 3277 ActuatorÎ See section 5.3.
− Attachment to actuators according toIEC 60534-6:
Î See section 5.4.
− Attachment according to VDI/
VDE 3847-1/-2:
Î See section 5.5 and section 5.6.
− Attachment to Type 3510 Micro-flow
ValveÎ See section 5.7.
− Attachment to rotary actuators according to VDI/VDE 3845:
Î See section 5.8.

3.2 Additional equipment
Solenoid valve
If the operating voltage for the solenoid
valve (12) fails, the signal pressure for thebooster is vented to the atmosphere. As a result, the actuator is vented and the valve
moves to its fail-safe position.
! NOTICE
The manual set point is automatically reset to
0 % after the solenoid valve is activated.
A different manual set point must be enteredagain (Code 1).
Position transmitter
The position transmitter (13) is a two-wiretransmitter and issues the travel sensor signal

EB 8384-2 ENDesign and principle of operation

as a 4 to 20 mA signal processed by the microcontroller.
Since this signal is issued independent of thepositioner’s input signal (minimum current
3.8 mA), the momentary travel/angle of rotation is controlled in real-time. Additionally,
the position transmitter allows positioner
faults to be indicated over a signal current of<2.4 mA or >21.6 mA.
Inductive limit switch
In this version, the rotary shaft of the positioner carries an adjustable tag which actuates the built-in proximity switch. The optional inductive switch (11) is connected to A1,
while the remaining software limit switch isconnected to A2.
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).
Leakage sensor
By upgrading the positioner with a leakage
sensor, it is possible to detect seat leakage
when the valve is in the closed position.
Binary input
Positioners can be optionally fitted with a binary input. The following actions can be triggered by changing the edge state:

EB 8384-2 EN− Transmit switching state [default]
The switching state of the binary input islogged.
− Set on-site operation write protection
While the binary input is active, no settings can be changed at the positioner.
Enabling configuration over Code 3 is
not active.
− Switch between AUTO/MAN
The positioner changes from the automatic mode
(AUTO) to the manualmode (MAN) or vice versa.
This function is not performed if the positioner is in the fail-safe position mode
(SAFE).
− Various diagnostic functions u EB 8389
(EXPERTplus valve diagnostics)
Note− The optional binary input can only be configured using the TROVIS-VIEW softwareand using the DD parameters (u EB 8389
on EXPERTplus valve diagnostics).
− The default switching state is with an open
switch.

3.3 Configuration using the
TROVIS-VIEW software
The positioner can be configured with
SAMSON's TROVIS-VIEW Software.
The positioner has for this purpose a serialinterface to allow the RS-232 or USB port of21

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 device module 3730-2 can be downloaded
free of charge from our website at u www.
samson.de > SERVICE & SUPPORT > Downloads > TROVIS-VIEW.
Further information on TROVIS-VIEW (e.g.

Mounting and start-up

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(M20x1.5)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.

7.1 Determining the fail-safe position
Define the fail-safe position of the valve (0 %) taking the valve type and the actuator's direction of action into account. Position the AIR TO OPEN/AIR TO CLOSE slide switch accordingly:− AIR TO OPEN setting
Signal pressure opens the valve, e.g. for a fail-close valve
The AIR TO OPEN setting always applies to double-acting actuators.
− AIR TO CLOSE setting
Signal pressure closes the valve, e.g. for a fail-open valve
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.

7.6 Initializing the positioner! WARNING
Risk of injury by exposed moving parts on the positioner, actuator or valve.
Do not touch or block exposed moving parts.
! NOTICE
The process is disturbed by the movement of the actuator or valve.
Do not perform the initialization while the process is running. First isolate the plant by closing
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 section 7.9) before mounting it on a different 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 7.6.1)− Nominal range (NOM)
Initialization mode for all globe valves (see section 7.6.2)− Manually selected range (MAN)
Initialization mode for globe valves with an unknown nominal range (see section 7.6.3)− Substitute calibration (SUb)This mode allows a positioner to be replaced while the plant is running, with the least
amount of disruption to the plant (see section 7.6.4).
For normal operation, simply start initialization by pressing the INIT key after mounting thepositioner on the valve and defining the fail-safe position and setting the volume restriction.

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 pneumaticallyby 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.

7.8 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 section 5.16.2) 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.
Note
The inductive limit switch replaces the software limit switch A1 with terminal assignment+41/–42.
Each switching position can optionally be set to indicate when the tag has entered the fieldor when it has left the field.
The second software limit switch remains effective, the function of the software limit switch A1
is disabled.
Software adaptation− Code 38 (inductive alarm is set to YES).
− The inductive limit switch is connected to the terminals +41/–42 (see section 5.16).
− The device is set up accordingly in the delivered state.

EB 8384-2 ENMalfunctions

9 Malfunctions
Malfunctions are indicated on the display byerror codes. Section 11.4 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: , Out of specification:
blinking, Maintenance alarm: ).
If 'No message' is assigned to the error 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 parameters of the DD. Refer to the operating instructions for the valve diagnostics
u EB 8389 on EXPERTplus valve diagnostics
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 functional fault in the positioner itself or in one of its peripherals oran initialization has not yet been successfully completed.
− Maintenance required
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 medium term.
− Maintenance demanded

to confirm the error message.

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 mounted actuator to be vented. As a result, the valve moves to the fail-safe position.
The fail-safe position depends on how thesprings are arranged in the pneumatic actuator (air-to-close or air-to-open).
When the supply air fails, when the optionalsolenoid valve is triggered and after reaching the shutdown signal, all positioner functions, except open/closed loop control, remain active (including diagnostics as well as
position and status feedback).
Tip
Emergency action in the event of valve or actuator failure is described in the associatedvalve and actuator documentation.
Î The plant operator is responsible for
emergency action to be taken in theplant.

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 and w-start andmust be Δw ≥ 25 % = 4 mA.
When the set point range of 0 to 100 % = 4 to 20 mA, the valve
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 two valves is divided
such, for instance, that the valves move through 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

The device continues functioning in emergency mode but it must be replaced as quickly as possible.
The emergency mode on the display is indicated by a blinking closedloop operation icon and 4 dashes instead of the position reading.
Note on the open-loop operation: If the measuring system has failed,
the positioner is still in a reliable state. The positioner switches toemergency mode where the position cannot be accurately controlled
anymore. However, the positioner continues operation according to its
set point so that the process remains in a safe state.

Status classification[Maintenance demanded]

Recommended action Return positioner to SAMSON AG for repair.
