Fig. 2 Range definition for positioner TZID
When mounting the positioner, ensure that the transfer of the stroke or rotation angle for
the position feedback is correct.
The maximum rotation angle is 60° for mounting to linear actuators and 120° for mount-
ing to rotary actuators.
Due to the high-resolution A/D conversion (> 8000 steps) no extra adjustment of the used
angle of rotation is necessary when mounting the positioner. Fine adjustment is done
later in the commissioning phase through electronic configuration (Autostroke).
For safety reasons, the range actually covered by the positioner's angle of rotation should
not reach the limits of the total range, but should be greater/smaller than these limits by
2 %. While commissioning the positioner, you can determine its angle of rotation by
using an electronic parameter.
The actually used angle of rotation should be at least 20 % of the total range. This value
can also be determined electronically in the commissioning phase.

• No further steps are required if the TZID positioner is delivered
mounted to an actuator.
• These operating instructions describe how to mount the positioner to
linear actuators in accordance with DIN/IEC 534 (lateral attachment
to NAMUR) and to rotary actuators in accordance with VDI/VDE
3845. Customized positioners for actuator-specific attachment require
special instructions, which are already delivered with the device or
can be ordered from us.
