Note
If the device is being operated on a cylinder, for reasons
associated with linearity you should run the Auto Adjust
function for rotary actuators
A TZIDC Control Unit with TZIDC Remote Sensor*
In this version, the components are supplied in two housings,
which together form one harmonized unit.
The following points should be observed during installation:
• Housing 1 (TZIDC Control Unit) contains the
electronics and pneumatics and is mounted separately
from the actuator.
• Housing 2 (TZIDC Remote Sensor) contains the
position sensor and is mounted on the linear and
rotary actuator.
* The TZIDC Remote Version is temporarily not available for
the marine version.
5 Compressed air supply
6 Set point signal
7 Remote position sensor
Note
To connect the TZIDC Remote Sensor, a cable with the
following specifications needs to be used:
• 3-wire, cross-section 0.5 to 1.0 mm
• shielded, with at least 85 % coverage
• Temperature range up to at least 100 °C (212 °F)
The cable glands must also be approved for a temperature
range up to at least 100 °C (212 °F). The cable glands require a
mounting for the shielding and strain relief for the cable in
addition.
B TZIDC Control Unit for remote position sensor
In this version the positioner is supplied without a position
sensor.
The following points should be observed during installation:
• Housing 1 (TZIDC Control Unit) contains the
electronics and pneumatics and is mounted separately
from the actuator.
• The remote position sensor is mounted on the linear
and rotary actuator. Follow the operating instructions
for the remote position sensor for mechanical
mounting!
