Note
If the device is being operated on a cylinder, for reasons
associated with linearity you should run automatic adjustment
for rotary actuators (refer to
Standard automatic adjustment
on page 46).
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.
Perform mechanical mounting as described in
Mechanical
mounting
on page 27.
• The electrical connection is performed as described in
Connection on device - TZIDC Control Unit with TZIDC
Remote Sensor
on page 40.
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
²
• 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.
ABB optionally offers a cable gland and cable for the
TZIDC Remote Version.
* The TZIDC Remote Version is temporarily not available for the marine
version.
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!
• The electrical connection is performed as described in
Connection on device - TZIDC Control Unit for remote
position sensor
on page 41.
