"TZIDC with remote position sensor"

In the TZIDC designed with a remote position sensor, the components are accommodated in
two housings, which together form one harmonized unit.
Housing 1 (control unit) contains the electronics and pneumatics along with the following
options (where applicable):
• Analog position feedback
• Digital position feedback
• Shutdown module
Housing 2 (remote sensor) contains the position sensor and is suitable for mounting on linear
and part-turn actuators.
The following options can be installed if required:
• Optical position indicator
• Mechanical feedback contacts designed as proximity switches or microswitches.
The two housings can be or are connected to a shielded 3-wire cable. The maximum cable
length is 10 m.
Installation and commissioning procedures are described in chapters
"Pneumatic connection" and 6 "Commissioning".
Procedures for connecting the electronic unit (housing 1) and the options (housings 1 and 2) are
described in chapter 4 "Electrical connections".
With remote sensors designed to protection class IP 67, ensure that the cover screws are pre-
tightened with approx. 50 Ncm and then firmly tightened with 250 ± 30 Ncm.
IMPORTANT (NOTE)
If the device is being operated on a cylinder, for reasons associated with linearity you should
run the Auto Adjust function for part-turn actuators.
