The diagnosis parameters of the TZIDC program inform the operator
about the operating conditions of the valve.
From this information the operator can derive which maintenance
works are required, and when.
Additionally, limit values can be defined for these parameters. When
they are exceeded, an alarm is reported.
The following values are e.g. determined:
- Number of movements performed by the valve
- Total travel
The diagnosis parameters and limit values can be called up, set, and
reset via HART communication, using the configuration program.

The TZIDC positioner’s operator panel with four pushbuttons allows
for
- operational monitoring
- manual control
- configuration
- fully automatic commissioning
The operator panel is protected by a cover which avoids
unauthorized access to the operating elements.

Commissioning the TZIDC positioner is especially easy. The
standard Autoadjust function for automatic adaptation of the device
parameters can be started by simply pressing a single front panel
button, and without knowing parameterization details.
Depending on the selected actuator type (linear or rotary), the
displayed zero position is automatically adapted:
- for linear actuators counter-clockwise (CTCLOCKW)
- for rotary actuators clockwise (CLOCKW).
Besides this standard function, a customized “Autoadjust” function is
available. The function is launched either via the operator’s panel or
HART communication.

The information indicated by the 2-line LC display is permanently
updated and adapted during operation, to inform the operator in an
optimal way.
During control operation (control with or without adaptation) the
following TZIDC data can be called up by pressing the pushbuttons
briefly:
- Up button: Current setpoint (mA)
- Down button: Temperature in device
- Up + Down buttons: Current control deviation
