In the case of the 'TZIDC Control Unit with TZIDC Remote Sensor'
design, the components are supplied in two housings, which
together form one harmonized unit.
Housing 1 (TZIDC Control Unit) contains the electronics and
pneumatics along with the following options, where applicable:
• Analog position feedback
• Digital position feedback
Housing 2 (TZIDC Remote Sensor) contains the position sensor
and allows for mounting on linear or rotary actuators.
If necessary, the following options can be installed if required:
• Optical position indicator
• Mechanical feedback contacts designed as proximity
switches or microswitches.
Connect the positioner (TZIDC Control Unit, housing 1) and
remote position sensor (TZIDC Remote Sensor, housing 2) while
following the instructions below:
• The sensor and the electronics have been matched. Ensure
that only devices with the same serial number are connected.

3 EMC Cable gland
4 Shielded connection cable
• 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.
• 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 TZIDC / TZIDC Control
Unit terminal assignment on page 33.
• If the TZIDC Control Unit is fastened so that it is it non-
conductive, the housing must be grounded (TZIDC Control
Unit and TZIDC Remote Sensor housing with the same
electric potential); otherwise control deviations could occur
with regard to analog position feedback.
• Use wire end ferrules when connecting.
