The TZIDC is an electronically configurable positioner with 

communication capabilities designed for mounting to pneumatic 

linear or rotary actuators. It features a small and compact design, a 

modular construction, and an excellent cost-performance ratio. 

Fully automatic determination of the control parameters and 

adaptation to the final control element yield considerable time savings 

and an optimal control behavior.

An I/P module with subsequent pneumatic amplifier is used to control 

the pneumatic actuator. The well-proven I/P module proportionally 

converts the permanent electrical positioning signal from the CPU 

into a pneumatic signal used to adjust a 3/3-way valve. 

The air flow for pressurizing or depressurizing the actuator is 

continuously adjusted. As a result, excellent control is achieved. 

When reaching the set point, the 3/3-way valve is closed in center 

position to minimize the air consumption. 

Four different pneumatics versions are available: for single-acting or 

double-acting actuators, each with “fail-safe” or “fail-freeze” function.

If the electrical power supply fails, the positioner output 1 is 

depressurized, and the pneumatic actuator’s return spring moves the 

valve to the defined safe position. In case of a double-acting actuator 

the second output 2 is additionally pressurized.

If the electrical power supply should fail, the positioner output 1 (and 

2, if applicable) is closed and the pneumatic actuator stops 

(“freezes”) the valve in the current position. If compressed air supply 

should fail, the positioner depressurizes the actuator.

The TZIDC positioner featuring standard pneumatic action is also 

suitable for integral mounting. 

The required holes are found at the back of the device. 

The benefit of this design is that the point for mechanical stroke 

measurement is protected and that the positioner and actuator are 

linked internally. No external tubing is required.

Microprocessor-based position control in the TZIDC provides for 

optimal results. The positioner features high-precision control 

functions and high operational reliability. Due to their elaborate 

structure and easy accessibility, the device parameters can be 

quickly adapted to the respective application. 

The total range of parameters includes: 

- Operating parameters 

- Adjustment parameters 

- Monitoring parameters 

- Diagnosis parameters 

- Maintenance parameters

3.1.1 Operating parameters 

Pos: 7.6 /Technische Daten / Datenblatt/Aktorik/Stellungsregler/TZIDC / TZIDC-200/Betrieb/Betriebsparameter @ 10mod_1176214346265_3101.doc @ 77343 

The following operating parameters can be set manually if required: 

Signal 

Signal min. 4 mA, max. signal 20 mA (0 ... 100 %) 

freely selectable for split-range operation 

min. range 20 % (3.2 mA) 

recommended range > 50 % (8.0 mA) 

Action (positioning signal) 

Increasing: Signal 4 ... 20 mA = position 0 ... 100 % 

Increasing: Signal 20 ... 4 mA = position 0 ... 100 % 

Characteristic curve (travel = f {signal}) 

Linear, equal percentage 1:25 or 1:50 or 25:1 or 50:1 or freely 

configurable with 20 reference points. 

Travel limit 

The positioning travel, i.e. the stroke or angle of rotation, can be 

reduced as required within the full range of 0 ... 100 %, provided that 

a minimum value of 20 % is observed. 

Shut-off function 

This parameter can be set separately for each end position. When 

the respective configured limit value is exceeded, the shut-off 

function causes immediate travel of the actuator until reaching the set 

end position. 

When the shut-off value is set to “0”, the position is further controlled, 

even in the respective end position. 

Travel time prolongation 

This function can be used to increase the max. travel time for full 

travel. This time parameter can be set separately for each direction. 

Important 

This function can only be used with the pneumatics with the 

safety function “fail-safe”. 

Switching points for the position 

This parameter allows you to define two position limits for signaling 

(see option “Module for digital position feedback”). 

Digital output 

The alarms generated in the TZIDC positioner can be polled via the 

digital output as a collective alarm. 

The desired information can be selected via the operator panel or 

remotely via the configuration program. 

The output can be set to “active high” or “active low”, as required. 

Digital input 

For the digital input, one of the following safety options can be 

selected. You may use the operator’s panel or configuration program 

to select an option. 

- No function (default) 

- Move to 0 % position 

- Move to 100 % position 

- Hold previous position 

- disable local configuration 

- Disable local configuration and operation 

- Disable any access (no local or remote access via a PC) 

The selected function is activated once the 24 V DC signal is no 

longer applied (< 11 V DC).

The TZIDC positioner has a special function for automatic adjustment 

of the parameters. 

Additionally, the control parameters can be set automatically (in 

adaptive control mode) or manually to optimally adapt them to the 

process requirements. 

Tolerance band 

When reaching the tolerance band the position is considered as 

corrected. From this point on, the position is further slowly readjusted until the dead band is reached. The factory setting for this 

parameter is 0.3 %. 

Dead band (sensitivity) 

When reaching the dead band, the position is held. The factory 

setting for this parameter is 0,1 %. 

Actuator spring action 

Selection of the sensor shaft rotating sense (looking into the open 

case), if the valve is moved to the safe position by the actuator spring 

(actuator is depressurized via Y1/OUT1). 

For double-acting actuators the actuator spring action corresponds to 

pressurizing the pneumatic output (OUT2). 

Display 0 ... 100 % 

Adjusting the display (0 ... 100 %) according to the direction of action 

for opening or closing the valve.

Various functions for permanent operational monitoring are 

implemented in the TZIDC operating program. The following states 

will be detected and indicated, e.g.: 

- 4 ... 20 mA signal out of range 

- 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

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.

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 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.

You can easily connect your TZIDC positioner to a PC, e.g., in the 

workshop or in the commissioning phase, by using the positioner’s 

LKS adapter (LKS = local communication interface). 

An RS-232 interface converter adapts the signals on the serial PC 

port to the level of the positioner’s LKS.

The FSK modem establishes a digital frequency-modulated 

communication (Frequency Shift Keying) with the TZIDC positioner. 

Tapping is possible at any chosen point of the 20 mA signal line. 

We recommend that you use an electrically isolated FSK modem. It is 

bus-compatible when used with isolating amplifiers. Even connecting 

explosion-protected field devices is possible, on condition that the 

FSK modem is run outside the hazardous area.
