1.4 Correct use

The TZIDC-110 positioner is an electro-pneumatic positioner for pneumatic final control
elements. 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 18-0.23 EN. Any other use is considered
as incorrect.
The signal current circuit and the input and output circuitry must meet the explosion pro-
tection requirements stipulated in the certificates (see chapter "Certificates" starting on
page 38).
The maximum permissible ambient temperature range of -40 °C to +85 °C (when using
proximity switches of type SJ2-S1N (NO): -25 °C to + 85 °C) must not be exceeded.

1.5 Qualified personnel

Only those persons familiar with the installation, commissioning, operation and mainte-
nance of the TZIDC-110 positioner or similar instruments who have the required qualifi-
cation and have read and understood the operating instructions are authorized to work

enced and know the relevant standards and regulations to be able to judge their assig-
ned tasks and recognize potential hazards. Only persons who are qualified or have been
trained adequately and who have the required certificates are authorized to work on
explosion-protected devices.
