Binary input

The positioner has an optional binary input.

The following actions can be performed over

the binary input:

4

Transfer switching state [default]

The switching state of the binary input is

logged.

4

Set local operation write protection

Settings cannot be changed at the

positioner while the binary input is ac

-

tive. The configuration enabled function

in Code 3 is not active.

4

Switch between AUTO/MAN

The positioner changes from automatic

mode (AUTO) mode into manual

mode (MAN) and vice versa.

No action is started if the positioner is in

the fail-safe position (SAFE).

4

Various diagnostic functions (refer to

EB 8389 EN on EXPERTplus valve diag-

nostics).

Note: The optional binary output can only

be configured using the TROVIS-VIEW soft

-

ware and over the DD parameters (refer to

EB 8389 EN on EXPERTplus valve diagnos

-

tics).

The default switching state is with an open

switch.

Connection to terminals A-B: Binary input

for DC voltage signals

Connection to terminals B-C: Contact input

for an external contact

3.2 Communication

The positioner is equipped with an interface

for HART

®

protocol (Highway Addressable

Remote Transducer) for communication pur

-

poses. Data are transmitted in a superim

-

posed frequency (FSK = Frequency Shift

Keying) on the existing signal loop for the 4

to 20 mA reference variable.

Either a HART

®

capable handheld commu

-

nicator or a computer with FSK modem can

be used to establish communication and op

-

erate the positioner.

3.2.1 Configuration using

TROVIS-VIEW software

Refer to Table 5 on page 33 for order num-

bers.

The positioner can be configured using the

TROVIS-VIEW software.

The positioner is equipped for this purpose

with an additional digital SERIAL INTERFACE

to allow a computer to be connected over an

adapter cable from the RS-232 or USB port

of the computer to the positioner.

The TROVIS-VIEW software enables the user

to easily set parameters in the positioner

and view process parameters online.

Note: The TROVIS-VIEW software is a com

-

mon operator interface for various smart

SAMSON devices. The software together

with a device-specific module allow the con

-

figuration and parameterization of the de

-

vice.

The device-specific module for Type 3731-3

can be downloaded free of charge from the

SAMSON website (Services > Software >

TROVIS-VIEW).
