2.1 Measuring and operating ranges of the positioner
Operating range for linear actuators:
The operating range for linear
actuators is ±45° symmetrically to
the longitudinal axis. The usable
span within the operating range
is at least 25° (recommended
figure 40°). The usable span
does not necessarily need to run
symmetrically to the longitudinal
axis.
Operating range of rotary actuators:
The usable span is 90°, which must
be entirely within the measuring
range, but does not necessarily
need to run symmetrically to the
longitudinal axis.
Note
During installation make sure
that the actuator travel or rotation
angle for position feedback is
implemented correctly.

(2) Operating range
2. Installation
1. Tighten the screws so that they are hand tight
2. Attach the follower guide (1) and clamp plates
(2) with screws (4) and spring washers (3) to the
actuator stem.

2.4 Mounting on a yoke
Fig. 4
1. Attach the mount bracket (2) with screw (4)
and washer (3) to the yoke (1).
1. Attach the lever (6) to the feedback shaft (5)
of the positioner (can only be mounted in one
position due to the cut shape of the feedback
shaft).
2. Using the arrow marks (4), check whether
the lever moves within the operating range
(between the arrows).
3. Hand-tighten the screw (7) on the lever.
4. Hold the prepared positioner (with the mount
bracket 1 still loose) on the actuator so that
the follower pin for the lever enters the follower
guide to determine which tap holes on the
positioner must be used for the mount bracket.
5. Secure the mount bracket 1 with screws 2 and
washers 3 using the relevant tap holes on the
positioner housing.
Tighten the screws as evenly as possible to ensure
subsequent linearity.
Align the mount bracket in the oblong hole to ensure
that the operating range is symmetrical.
Set the valve mid stroke and align the lever
horizontal (item 6 fig. 3).
Then tighten mounting bolt (item 4 fig. 4) (lever
moves between the arrow marks item 4 fig. 3).
2.3 Mounting lever and bracket on the positioner
Fig. 3
Note
Positioner mounting threaded holes and bracket
holes, depend on the actuator type used. Select to
suit, to ensure the follower pin has free movement in
the follower guide over entire valve travel.

2.5 Mounting on a column
Fig. 5
1. Hold the mount bracket (3) in the proper
position on the column (2).
2. Insert the U-bolts (1) from the inside of the
column (2) through the holes of the mount
bracket.
3. Add the washers (4) and nuts (5).
4. Tighten the nuts so that they are hand-tight.
Note
Adjust the height of the positioner on the cast
iron yoke or columnar yoke until the lever is
horizontal (based on a visual check) at half
stroke of the valve.
2.6 Positioner linkage
(1) Increase linkage
(2) Decrease linkage
The scale on the lever indicates the
link points for the various stroke ranges
of the valve.
Move the bolt with the follower pin in
the oblong hole of the lever to adjust
the stroke range of the valve to the
working range for the position sensor.
Moving the link point inwards increases
the rotation angle of the sensor. Moving
the link point outwards reduces the
rotation angle of the sensor.
Adjust the actuator stroke to make
use of as large an angle of rotation
as possible (symmetrical around the
center position) on the position sensor.
Recommended range for linear actuators: −28 to 28°
Minimum angle: 25°
Note After mounting, check whether the positioner is operating within the measuring range.

2.7 Position of the actuator bolt
The actuator bolt for moving the potentiometer lever can be mounted permanently on the lever itself or on
the valve stem. Depending on the mounting method, when the valve moves the actuator bolt performs either
a circular or a linear movement with reference to the center of rotation of the potentiometer lever. Select
the chosen bolt position in the HMI menu in order to ensure optimum linearization. The default setting is
actuator bolt on lever

2.10 Mounting the adapter on the positioner
1. Determine the mounting position (parallel to
actuator or at 90° angle).
2. Calculate the rotational direction of the actuator
(right or left).
3. Move the part-turn actuator into the home
position.
4. Pre-adjust feedback shaft.
To make sure that the positioner runs within the
operating range (refer to measuring and operating
ranges of the positioner on page 4), the mounting
position as well as the basic position and rotation
direction of the actuator must be considered when
determining the adapter position on axis 1. For
this purpose, the feedback shaft can be adjusted
manually so that the adapter 3 can be attached in
the correct position.
5. Place the adapter in the proper position on the
feedback shaft and fasten with threaded pins
2. One of the threaded pins must be locked
in place on the flat side of the feedback shaft.

Join the pipe connections according to the designation, observing the following points:
-All pneumatic piping connections are located on the right-hand side of the positioner. ¼ 18 NPT tap holes
are provided for the pneumatic connections. The positioner is labeled according to the tap holes available.
-We recommend that you use a pipe with dimensions of 12 × 1.75 mm.
-The supply air pressure required to apply the actuating force must be adjusted in line with the output
pressure in the actuator. The operating range of the positioner is between 1.4 to 6 bar (20 to 90 psi).
2.15 Pneumatic connections
Information on double acting actuators with spring-return mechanism
On double-acting actuators with spring-return mechanism, a pressure that significantly exceeds the supply
air pressure value can be generated during operation by the springs in the chamber opposite the springs.
This may damage the positioner or adversely affect control of the actuator.
To eliminate the possibility of this occurring, it is recommended to install a pressure compensation valve
between the springless chamber and the supply air for these types of applications. It enables the increased
pressure to be transferred back to the air inlet line.
The opening pressure of the check valve should be < 250 mbar (< 3.6 psi).
