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

The DTM (Device Type Manager) for TZIDC is based on the

FDT/DTM technology (FDT 1.2) and can be integrated in a process

control system or loaded in a PC with the DSV401 (SMART VISION)

program. This allows you to work with the same user interface in the

commissioning phase, during operation, and for service tasks for

monitoring the device, setting parameters, and uploading data.

Communication is based on the HART protocol. It occurs via a local

interface connection (LKS) or in frequency-modulated mode using an

FSK-modem connected at any chosen point of the 20 mA signal line.

Communication has no effect on operation. Newly set parameters are

saved in the non-volatile memory directly upon the download into the

device, and become active immediately
