Communication - Samson 3730-2 Mounting And Operating Instructions

Design and principle of operation
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).
Leakage sensor
By upgrading the positioner with a leakage
sensor, it is possible to detect seat leakage
when the valve is in the closed position.
Binary input
Positioners can be optionally fitted with a bi-
nary input. The following actions can be trig-
gered by changing the edge state:
− Transmit switching state [default]
The switching state of the binary input is
logged.
− Set on-site operation write protection
While the binary input is active, no set-
tings can be changed at the positioner.
Enabling configuration over Code 3 is
not active.
− Switch between AUTO/MAN
The positioner changes from the auto-
matic mode (AUTO) to the manual
mode (MAN) or vice versa.
This function is not performed if the posi-
tioner is in the fail-safe position mode
(SAFE).

Note
− The optional binary input can only be con-
figured using the TROVIS-VIEW software
and using the DD parameters (u EB 8389
on EXPERTplus valve diagnostics).
− The default switching state is with an open
switch.

3.2 Communication

The positioner can be configured with
SAMSON's TROVIS-VIEW Configuration
and Operator Interface.
The positioner has for this purpose a serial
interface to allow the RS-232 or USB port of
a computer to be connected to it over an
adapter cable.
The TROVIS-VIEW software enables the user
to easily configure the positioner as well as
view process parameters online.
Note
TROVIS-VIEW provides a uniform user inter-
face that allows users to configure and pa-
rameterize various SAMSON devices using
device-specific database modules. The de-
vice module can be downloaded free of
charge from our website at u www.samson.
