Operating parameters

The following operating parameters can be set manually if required:

Setpoint signal

0 … 100 % freely selectable for split-range operation

For 4 … 20 mA and HART version:

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

— Min. range 20 % (3.2 mA)

— Recommended range > 50 % (8.0 mA)

Action (setpoint signal)

Increasing:

Position value 0 … 100 % = direction 0 … 100 %

Decreasing:

Setpoint signal 100 … 0% = direction 0 … 100%

Characteristic curve (travel = f {setpoint 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.

Device parameters

General remarks

Microprocessor-based position control in the positioner

optimizes control. 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

— Diagnostics parameters

— Maintenance parameters

be reduced as required within the full range of 0 … 100 %,

provided that a minimum value of 20% is observed.

“Fail-safe” function

If the electrical supply power 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.

Change from two to one column

“Fail-freeze” function

If the electrical supply power fails, the positioner output 1 (and

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

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

air supply power fails, the positioner depressurizes the actuator.

The air flow for pressurizing or depressurizing the actuator is

continuously adjusted. As a result, excellent control is

achieved. When reaching the setpoint, 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.

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.

The air flow for pressurizing or depressurizing the actuator is

continuously adjusted. As a result, excellent control is

achieved. When reaching the setpoint, the 3/3-way valve is

closed in center position to minimize the air consumption.

Brief description

The TZIDC-200 is an electronically configurable positioner with

communication capabilities designed for mounting to

pneumatic linear or part-turn 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.

Universal transmitter – powerful and flexible

The backlit display can be easily rotated without the need for

any tools. The contrast is adjustable and the display fully

configurable. The character size, number of lines and display

resolution (number of decimals) can be set as required. In

multiplex operation, several different display options can be

pre-configured and invoked one after the other.

The smart modular design of the transmitter unit allows for

easy disassembly without the need to unscrew cables or

unplug connectors.

Whether count pulses, 20 mA signals or the status output are

active or passive, the universal transmitter always delivers the

correct signal. HART is used as the standard protocol.

Optionally, the transmitter is available with PROFIBUS PA or

FOUNDATION Fieldbus communication.

The universal transmitter simplifies the spare parts inventory

and reduces the stockholding costs.
