22 Electro-pneumatic positioner TZIDC-220 42/18-82 EN
3.3.3 Overview
Two threaded bore holes
1/2 - 14 NPT or M20 x 1.5 are
available on the left 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.
The screw terminals inside the
case are assigned as follows:
1 Not used
2 Service switch for the
shutdown module
3 Terminals for the
shutdown module
4 Kit for digital position
feedback, either proximity
switches or 24 V micro-
switches
5 Same as 4
6 Bus terminals
7 Grounding screw

NOTICE
Electromagnetic interference
• Do not run bus/signal lines close to power lines. Power lines produce
interference in their near vicinity which may affect the electrical capabil-
ities of the bus/signal lines.
• Always use shielded cables conforming to the standards for the bus
lines, to ensure electromagnetic compatibility (EMC). When running the
device with the option modules (proximity switches, microswitches,
shutdown module) use shielded cables for these modules as well. All
cable shields must be kept as short as possible and have to be con-
nected to protective ground on both sides (use the grounding screw in
the TZIDC-220 connection compartment on the device side).
• Keep the case closed. Otherwise, the positioning action may be
affected through EMI, resulting in a permanent positioning error, espe-
cially when the Autoadjust function is performed with the case open.
