42/18-54 EN Electro-pneumatic positioner TZID 17
Before mounting the positioner:
• Determine the actuator’s direction of rotation (counterclockwise or clockwise).
• Determine the mounting position (in parallel with the actuator or shifted by 90°).

NOTICE
- The TZID rotating shaft can only be rotated in the direction of the indicat-
ing arrow on the shaft. There are no mechanical stops to limit the actua-
tor movement. Improper mounting can damage the device and void
warranty.
- When mounting the positioner, make sure that there is a loose fit
between the adapter at the positioner and the actuator shaft. It must be
possible to move the adapter manually within the range of 0.1...0.3 mm.
If required, readjust the mounting bracket.
The TZID positioner is prepared
for this type of mounting when it
is delivered. No adapter settings
are required.
• Couple the positioner’s
adapter with the rotary actu-
ator’s shaft.
• Turn TZID clockwise by
approx. 15° (see Fig. 9).
• Fasten TZID with screws.
