•    Higher vibration immunity

•    excellent accessibility

•    increased protection class

•    stainless steel housing

Reliable and accurate

Using pneumatic actuators with integrated position sensor.

‘Fail-safe’ safety function

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

depressurized and the return spring in the pneumatic

actuator moves the valve to the safe position. In case of a

‘double-acting’ version, output 2 is additionally pressurized.

‘Fail-freeze’ function

If the electric power supply fails, the positioner Output 1

(and Output 2 if applicable) is closed and the pneumatic

actuator blocks the valve in the current position. If the

compressed air supply power fails, the positioner

depressurizes the actuator.

Use

The positioner has a built-in operating panel providing a 2

line LCD indicator and 4 operating buttons for

commissioning, configuration and monitoring during live

operation.

Alternatively, the appropriate configuration program can be

used via the available communication interface.

Communication

Communication with the TZIDC-210 occurs via PROFIBUS PA®.

Modular design

The basic model can be enhanced at any time by retrofitting

optional equipment.

Option modules can be installed for analog and digital

position feedback.

Additionally, a mechanical position indicator, proximity

switches or 24 V microswitches are available for indicating

the position independently of the mother board function.

Brief description

The TZIDC-210 is an electronically configurable positioner

with communication capabilities designed for mounting on

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 positioner allow for considerable time

savings as well as optimum control behavior.

Pneumatics

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

setpoint signal from the CPU into a pneumatic signal used to

adjust a 3/3-way valve.

Dosing of the air flow for pressurizing or depressurizing the

actuator is continuously adjusted. As a result, excellent

control results are achieved. When reaching the setpoint, the

3/3-way valve is closed in center position to minimize the air

consumption.

The pneumatic system can be supplied in four versions: for

single acting and double acting actuators and each with the

‘fail-safe’ / ‘fail-freeze’ safety function.

Diagnosis parameters

The diagnostics parameters in the positioner’s operating

program provide information about the operating conditions

of the valve.

From this information the operator can derive what

maintenance work is required, and when.

Additionally, limit values can be defined for these parameters.

When they are exceeded, an alarm is reported.

So, for example, the following operating values are

determined:

• Number of movements of the final control element

• Sum of individual actuator travel events

The diagnostic parameters and limit values can be called up,

set and reset using the configuration program.

Operator panel

The integrated operating panel of the positioner has four

operating buttons which allow the device to be operated with

an open housing cover.

The following functions can be controlled via the function

keys:

• Observe live operation

• Manual intervention during live operation

• Parameterization of the device

• Fully automatic commissioning

Operations monitoring parameters

Various functions for continuous device monitoring are

implemented in the operating program for the positioner.

The following states will be detected and indicated, e.g.:

• Internal positioning time-out

• Sensor monitoring

• Backup monitoring

While automatic commissioning is in progress, the current

state is continuously indicated on the integrated LCD

indicator. Remaining messages can be retrieved via the user

interface.

The fieldbus enables users to implement enhanced

monitoring in the control system. A special window displays

the most important process variables ONLINE, e.g. the

setpoint signal (in %), the position (in %), the control

deviation (in %) as well as the status messages.
