enters the follower guide to determine which tap holes on
the positioner must be used for the mount bracket.

TZIDC DIGITAL POSITIONER | CI/TZIDC/ATEX/IECEX-EN REV. C 15
5.Secure the mount bracket 1with screws 2and 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 (lever
moves between the arrow marks 4).

3.Add the washers 4and nuts 5.
 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.

Figure 11: Positioner 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.

Position of 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.

Figure 15: 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 General on page 13), 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 3can 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.
