Connection on device - TZIDC Control Unit for remote position sensor

1 Terminals for remote position sensor
2 Remote position sensor
Figure 21: Connection of TZIDC Control Unit with remote position sensor (example)
With the TZIDC designed for remote position sensors, the
positioner is supplied without a position sensor.
The TZIDC Control Unit contains the electronics and pneumatics
along with the following options (where applicable):
• Plug-in module for analog feedback
• Plug-in module for digital feedback
Any position sensor (4 to 30 kΩ, with line break detection
4 to 18 kΩ) can be connected.
Connect the positioner (TZIDC Control Unit) and remote position
sensor while observing the following instructions:
• A shielded 3-wire cable with a maximum length of 10 m
(33 ft) must be used for the connection.
• Route the cable into the terminal compartment through
the EMC cable glands. Ensure that the shielding is
secured correctly in the EMC cable glands.

4 Shielded connection cable
• Connect the cables in accordance with the electrical
connections and tighten the screws of the terminals so
that they are hand-tight.
• The electrical connection of the TZIDC Control Unit and
the optional modules are described in Positioner /
TZIDC Control Unit Electrical Connection on page 24.
• If the TZIDC Control Unit is fastened such that it is it non-
conductive, the housing must be grounded (TZIDC
Control Unit and remote position sensor housing with the
same electric potential); otherwise control deviations
could occur with regard to analog position feedback.
• Use wire end ferrules when connecting.
• The pneumatic outputs must be connected to the
actuator using cables of at least Ø 6 mm (0.23 in).
• If the device is being operated on a cylinder, for reasons
associated with linearity you should run automatic
adjustment for rotary actuators.
