The regulations, standards and directives referred to in this manual are applicable in Ger- many. When using the TZID positioner outside the German jurisdiction, the relevant reg- ulations, standards and directives applicable in the country where the device is used must be observed.
WARNING • The TZID rotating shaft can only be rotated in the direction of the indi- cating arrow on the shaft. There are no mechanical stops to limit the actuator movement. Improper mounting can damage the device and void warranty.

Type plates indicating the degree of explosion protection 1.4 Correct use The TZID positioner is an electro-pneumatic positioner for pneumatic final control ele- ments. It is designed for being attached to linear and rotary actuators following the instructions in this manual. The positioner may be used only for the applications listed in these operating instructions or in the data sheet 18-0.20 EN.
18-0.20 EN. 2.2 CE compliance information We declare that we are the manufacturer of the TZID positioner and that the product con- forms with the EMC Directive 89/336/CEE as of May 1989 and meets the requirements of the following standards: •...
Installing and commissioning 3.1 Mechanical mounting 3.1.1 General • 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 IMPORTANT linear actuators in accordance with DIN/IEC 534 (lateral attachment to NAMUR) and to rotary actuators in accordance with VDI/VDE 3845.
3.1.2 Operating conditions at the installation site Before installing check to ensure that the specifications in terms of safety and control applicable to the TZID positioner will not be exceeded at the installation site of the actuator or final control element.
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).

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...
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.

- 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.

A pressure gauge block is available for indicating the supply air pressure and output pressure. Fasten the pressure gauge block to the side of the TZID positioner. Make sure that the O-ring seals are positioned properly to ensure tight fitting.

Two threaded bore holes 1/2 - 14 NPT or M20 x 1.5 are available on the right-hand side as the cable entry into the case. One is equipped with a cable gland and in the other a pipe plug is mounted. In its standard version the TZID positioner is delivered with the cable gland already installed.

Any adjustment that goes beyond this scope requires the method described below. Commissioning the positioner remotely via a PC with special TZID software Commissioning through the PC is done via the communication port and a special adapter.
3.4.4 Setting parameters for current operation Normally, “Controlling adaptive“ at operating level 1 is selected for current operation. It is only necessary to select “Controlling fixed“ if the positioner is working unstable in adap- tive mode. 42/18-54 EN Electro-pneumatic positioner TZID...
Control lug within proximity switch -> state 1 (control current > 3 mA) The TZID positioner has two screws for alarm limit adjustment (see Fig. 21). The screws are protected against unwanted turning. To adjust the alarm limits, push in the adjust- ment screws with a screw driver to enable snapping in.

4.1 Operating level 1 When an input signal > 3.6 mA is applied, the positioner starts up at operating level 1. Four operating modes can be selected through manual control. TZID has a rotary switch with positions 0, 1, 2 and 3.
The arrow indicates that a change-over to operating level 2 is in progress. If the positioner was working in the mode “Controlling adaptive”, the newly deter- mined values are saved. This is indicated by the characters “EE” shown on the dis- play. 42/18-54 EN Electro-pneumatic positioner TZID...

If you should modify or manipulate the electronics of a positioner without explosion protection, the positioner's warranty will expire immediately. IMPORTANT The TZID positioner is virtually maintenance-free. We recommend to check the control position periodically for conformity with the toler- ance limit.
