and Tests (out-of-service diagnostics) are
canceled and the diagnosis data are re-
set once.
4
External solenoid valve connected
The triggering of an external solenoid
valve is recognized.
4
Leakage sensor
The “External leakage soon to be ex-
pected” error is set. The error is reset
when the edge control is set to OFF. The
message remains saved in the logging.
Note: The optional binary output can only
be configured using the TROVIS-VIEW soft-
ware and over the DD parameters (refer to
EB 8389S on EXPERTplus valve diagnostics).
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
3.3 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.
3.3.1 Configuration using
TROVIS-VIEW software
Refer to Table 5 on page 34 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 TROVIS SAFE
3731-3 can be downloaded free of charge
from the SAMSON website (Services > Soft-
ware > TROVIS-VIEW).
Additional information on TROVIS-VIEW
(e.g. system requirements) can found on the
SAMSON website and in the Data Sheet
T 6661.
