Design and principle of operation

3 Design and principle of oper-

ation

The positioner is mounted on pneumatic con-

trol valves and is used to assign the valve

position (controlled variablex) to the control

signal (set pointw). The positioner compares

the control signal of a control system to the

travel or rotational angle of the control valve

and issues a signal pressure (output vari-

abley) for the pneumatic actuator.

The positioner mainly consists of an electric

travel sensor system, an analog i/p convert-

er with a downstream air capacity booster

and the electronics with the microcontroller.

When a system deviation occurs, the actua-

tor is either vented or lled with air. If neces-

sary, the signal pressure change can be

slowed down by a volume restriction. The

signal pressure supplied to the actuator can

be limited by software or on site to 1.4, 2.4

or 3.7bar.

The xed ow regulator ensures a constant

air ow to the atmosphere, which is used to

ush the inside of the positioner housing and

to optimize the air capacity booster. The i/p

converter is supplied with a constant up-

stream pressure by the pressure regulator to

compensate for any uctuations in the supply

pressure.

Design and principle of operation

The positioner communicates and is powered

using IEC61158-2 transmission technology

conforming to PROFIBUS-PA specications.

As a standard feature, the positioner comes

with a binary input for DC voltage signals to

signalize process information over the

PROFIBUS-PA network.

The extended EXPERTplus diagnostics are in-

tegrated into the positioner. They provide in-

formation on the positioner and generate di-

agnostic and status messages, which allow

faults to be pinpointed quickly.

The positioner is suitable for the following

types of attachment using the corresponding

accessories:

−Direct attachment to SAMSON

Type3277 Actuators

−Attachment to actuators according to

IEC60534-6 (NAMUR)

−Attachment according to VDI/VDE3847

−Attachment to Type3510 Micro-ow

Valve

−Attachment to rotary actuators according

to VDI/VDE3845

3.1 Additional equipment

Solenoid valve

If the voltage supply for the solenoid valve

(12) fails, the supply pressure for the i/p

converter is vented to the atmosphere. The

positioner can no longer operate and the

control valve moves to the fail-safe position

determined by the actuator, regardless of the

set point.

The manual set point is also reset to 0 % af-

ter the solenoid valve is activated!

A different manual set point must be entered

again (Code 1).

Inductive limit switch

In this version, the rotary shaft of the posi-

tioner carries an adjustable tag which actu-

ates the built-in proximity switch.

External position sensor

In this version, only the sensor is mounted to

the control valve. The positioner is located

separately from the valve. The connection of

x and y signals to the valve is established by

cable and piping for air (only without induc-

tive limit switch).

Binary input BI1

As a standard feature, the positioner comes

with a binary input for DC voltage signals to

signalize process information over the

PROFIBUS-PA network.

Binary input BI2

This binary input BI2 is optional. It is an ac-

tive input which is powered by the positioner

to connect a oating contact. The switching

state of the oating contact can be indicated

over the PROFIBUS-PA network.
