1.4 Correct use
The TZIDC positioner is an electro-pneumatic positioner with flameproof enclosure 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 18-0.22 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.
