ABBElectro-Pneumatic Positioner TZIDC

- position out of the adjusted range 

- positioning time-out (adjustable time parameter) 

- position controller inactive 

- counter limits (settable in the diagnosis phase) exceeded 

While automatic commissioning is in progress, the current state is 

continuously indicated on the integrated LCD. 

During operation, the LCD shows the most important process 

variables: 

- current position (in %), 

- malfunctions, alarms, messages (as code) 

Access to extended monitoring parameters is possible via HART 

communication and the DTM. 

3.1.4 Diagnosis parameters 

Pos: 7.13 /Technische Daten / Datenblatt/Aktorik/Stellungsregler/Allgemein/Betrieb/Diagnoseparameter @ 10mod_1176214500906_3101.doc @ 77406 

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

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.
