Communication K 1.11 K 1.21
Leakage sensor at binary input 2 The connection of a leakage sensor at binary input 2 (by selecting
LEAKAGE SENSOR in CONFIG_BINARY_INPUT2 parameter of
the AO Transducer Block) causes:
4Information specified in XD_ERROR_EXT parameter in the AO
Transducer Block and the generation of a diagnostic alarm
which is logged
4The state of the binary input is reported in BINARY_INPUT2
parameter in the Transducer Block
Diagnostic alarm
“Device not initialized“ The diagnostic alarm “Device not initialized” is generated when the positioner is not initialized and the condensed status is set to
“Maintenance alarm”.
Display of the working range
FINAL_VALUE_RANGE The correction of the working range FINAL_VALUE_RANGE over on-site operation of the positioner (Code 8/9) is also transferred
over fieldbus in firmware version K 1.21 and higher.
Inactivated internal solenoid valve A masking allows to be set whether an inactivated internal sole-
noid valve generates an AO block error and a resulting block
alarm.
SOLENOID_SELECT parameter The SOLENOID_SELECT parameter in firmware K 1.21 and
higher allows to be set whether a “Maintenance now“ block error
of the AO Transducer Block results in an output error in the AO
Block.
TOT_VALVE_TRAV_LIM parameter New range: 1000 … 990 000 000
K 1.22
Working range
FINAL_VALUE_RANGE The working range FINAL_VALUE_RANGE of the AO Transducer Block is compared on entering it with TRANSM_PIN_POS.
If the TRANSM_PIN_POS parameter is changed, the positioner
checks whether the setting and unit match the current working
range FINAL_VALUE_RANGE. If this is not the case, the
FINAL_VALUE_RANGE parameter is set to 0 to 100 %.
VALVE_TYPE parameter The parameter of the AO Transducer Block is set depending on
the selected PIN_POS. The last setting is kept when VALVE_TYPE
is set to OFF.
FINAL_VALUE parameter The manipulated variable is scaled with FINAL_VALUE_ RANGE
in firmware K 1.22 and higher, and not with XD_SCALE.
Display of O/S mode in
AO Transducer Block If the AO Transducer Block is set to O/S mode, this is indicated in the positioner display by MAN/AUTO.

3 Design and principle of
operation
The electropneumatic positioner is attached
to pneumatic control valves. It is used to as-
sign the valve stem position (controlled vari-
able x) to the control signal (reference vari-
able w). The input signal received from a
control system is compared to the travel or
rotational angle of the control valve, and a
pneumatic signal pressure (output variable
y) is produced.
The positioner consists of a travel sensor sys-
tem proportional to resistance, an analog
i/p converter with a downstream booster
and the electronics unit with microcontroller.
When a deviation occurs, the actuator is
pressurized or vented. If required, the
changes in the signal pressure can be
slowed down by a connectable Q restric-
tion. The signal pressure supplied to the ac-
tuator can be limited by software or on site
to 1.4, 2.4 or 3.7 bar.
A constant air stream to the atmosphere is
created by the flow regulator (9) with a
fixed set point. The air stream is used to
purge the inside of the case as well as to op-
timize the air capacity booster. The i/p
module (6) is supplied with a constant up-
stream pressure by the pressure regulator
(8) to make it independent of the supply air
pressure.

fieldbus
IEC 61158-2

The positioner communicates and is pow-
ered using IEC 61158-2 transmission tech-
nology conforming to FOUNDATION™
fieldbus specification.
As a standard feature, the positioner comes
with a binary input for DC voltage signals to
signalize process information over the
FOUNDATION™fieldbus.
3.1 Additional equipment
Version with solenoid valve
If the operating voltage for the solenoid
valve (12) fails, the supply pressure for the
i/p module is vented to the atmosphere. The
positioner can no longer operate and the
control valve moves to the fail-safe position
determined by the actuator, independent of
the reference variable.
NOTICE
In manual mode (MAN), the manual set
point is also reset to 0 %. A different manual
set point must be entered again (Code 1).
Version with inductive limit switch
The rotary shaft of the positioner carries an
adjustable tag which actuates the installed
proximity switch.
Version with binary contact
All positioners are fitted with a binary input
for DC voltage signals over which process
information can be issued over the
FOUNDATION™ fieldbus network.
Another optional binary input is an active
input powered by the positioner to connect
a floating contact. Its switching condition
can also be issued over the FOUNDATION™
fieldbus network.
Version with external position sensor
In this version, only the sensor is mounted to
the control valve. The positioner is located
separately from the valve.
The connection of x and y signals to the
valve is established by cable and piping for
air (only without inductive limit switch).
EXPERT+extended valve diagnostics
See Table 5 on page 42 for order numbers.
EXPERT+upgrades the standard EXPERT di-
agnostics firmware incorporated in the
positioner. The upgraded version provides
extended functions to pinpoint valve param-
eters that have worsened, allowing the user
to plan predictive maintenance and service
work before malfunctions can affect the pro-
cess and may cause unscheduled plant shut-
downs.
The extended EXPERT+diagnostics can be
activated later at the positioner when
EXPERT+is not already activated on delivery
of the positioner. The required activation
code or an EXPERT+USB dongle can be
purchased to activate EXPERT+.
3.2 Communication
The positioner is completely controlled over
the digital signal transmission implemented
according to FOUNDATION™ fieldbus spec-
ification.
Data are transmitted as bit-synchronous
current modulation at a rate of 31.25 kbit/s
Design and principle of operation
EB 8384-5 EN 13

over twisted-pair cables conforming to
IEC 61158-2.
Note: In the case, complex functions are
started in the positioner, which require a
long calculation time or lead to a large
quantity of data being stored in the volatile
memory of the positioner, the alert “busy” is
issued over DD.
This alert is not a fault alarm and can sim-
ply be confirmed.
Configuration using TROVIS-VIEW software
The positioner can be configured using
TROVIS-VIEW Configuration and Operator
Interface software.
The positioner is equipped with an addi-
tional digital SERIAL INTERFACE to connect
the RS-232 or USB port of the computer to
the positioner over an adapter cable.
The TROVIS-VIEW software enables the user
to easily set parameters in the positioner
and view process parameters online.
Configuration using the NI-FBUS™
Configurator
The NI-FBUS™ Configurator from National
Instruments can also be used to configure
the positioner. For this purpose, an interface
card must be installed in a computer to con-
nect it to the FOUNDATION™ fieldbus.
The integrated function blocks are linked
using the NI-FBUS™ Configurator.

NOTICE
Attach the positioner to the control valve,
observing the following instructions to avoid
damaging the positioner.
–
Use only the mounting parts/accessories
listed in the Tables 1 to 5 (pages 40 to
42) to mount the positioner. Observe the
type of attachment!
–
Observe the assignment between lever
and pin position (see travel tables on
page 19)!
Lever and pin position
The positioner is adapted to the actuator
and to the rated travel by the lever on the
back of the positioner and the pin inserted
into the lever.
The travel tables on page 19 show the maxi-
mum adjustment range at the positioner. The
travel that can be implemented at the valve
is additionally restricted by the selected
fail-safe position and the required compres-
sion of the actuator springs.
The positioner is standard equipped with the
lever M(pin position 35).
Note: If the standard mounted lever M (pin
position 35) is replaced, the newly mounted
lever must be moved once all the way as far
as it will go in both directions to adapt it to
the internal measuring lever.

Actuator with 120 cm²
Depending on the type of positioner attach-
ment, the signal pressure is routed either left
or right of the yoke through a bore to the
actuator diaphragm. Depending on the
fail-safe action of the actuator "Actuator
stem extends" or "Actuator stem retracts"
(valve closes or opens if the supply air fails),
the switchover plate (9) must first be at-
tached to the actuator yoke. Align the
switchover plate with the corresponding
symbol for left or right attachment according
to the marking (view looking onto the
switchover plate).
1. Mount connecting plate (6) or pressure
gauge bracket (7) with pressure gauges
onto the positioner, making sure both
seal rings (6.1) are seated properly.
2. Remove vent plug (4) on the back of the
positioner and close the signal pressure
output "Output 38" on the connecting
plate (6) or on the pressure gauge
bracket (7) with the stopper (5) included
in the accessories.
3. Place follower clamp (3) on the actuator
stem, align and screw tight so that the
mounting screw is located in the groove
of the actuator stem.
4. Mount cover plate (10) with narrow side
of the cut-out opening (Fig. 4, left) point-
ing towards the signal pressure connec-
tion. Make sure that the bonded gasket
(14) points towards the actuator yoke.
5. 15 mm travel: Keep the follower pin (2)
at lever M(1) on the back of the
positioner in the pin position 35 (deliv-
ered state).
7.5 mm travel: Remove the follower pin
(2) from the pin position 35, reposition it
in the bore for pin position 25 and
screw tight.
6. Insert formed seal (15) in the groove of
the positioner casing.
7. Place positioner on the cover plate (10)
in such a manner that the follower pin
(2) rests on the top of the follower clamp
(3). Adjust the lever (1) correspondingly
and open the positioner cover to hold
the positioner shaft in position at the cap
or the switch (Fig. 20).
The lever (1) must rest on the follower
clamp with spring force.
Mount the positioner on the cover plate
(10) using the two fixing screws. During
the installation make sure that the seal
ring (10.1) is inserted in the bore of the
cover plate.
8. Mount cover (11) on the other side.
Make sure that the vent plug points
downwards when the control valve is in-
stalled to allow any condensed water
that collects to drain off.
