    All other items are part of the mounting kit which has to be ordered separately. The TZID positioner comes with the lever (4) already installed. All other items are deliv- ered in a separate package. The lever is available in two lengths: for 10 to 85 mm strokes (standard version) and for strokes 10 to 150 mm (special version, to be ordered sepa- rately).

  • Page 15 A scale on the lever helps you to determine the valve stroke range. Use the lever scale to set the bolt to the appropriate position. A rough adjustment is suffi- cient. The fine adjustment will be done later in the commissioning phase using the Autostroke function. 42/18-54 EN Electro-pneumatic positioner TZID...

  • Page 16: Mounting To Rotary Actuators

    Fig. 7 Mounting to rotary actuators The TZID positioner is mounted to the rotary actuator using a mounting bracket (7), which has to be ordered separately. At the positioner’s back you can find four threaded holes M6 arranged on a 50 mm circle diameter, into which the mounting bracket’s fasten- ing screws (1) are screwed.
