Configuration Using The Trovis-View Software; Volume Restriction - Samson TROVIS 3730-3 Mounting And Operating Instructions

Design and principle of operation
3.2 Configuration using the
TROVIS-VIEW software
The positioner can be configured with
SAMSON's TROVIS-VIEW Software
(version 4). For this purpose, the positioner
has a digital interface (SSP) to allow the USB
port of a computer to be connected to it
using an adapter cable.
Tip
SAMSONWe recommend using the isolated
USB interface adapter (order no. 1400-
9740). Replace older adapters with RS-232
interface.
The TROVIS-VIEW software enables the user
to easily configure the positioner as well as
view process parameters online.
Note
TROVIS-VIEW can be downloaded free of
charge from our website at www.samson.de

3.3 Volume restriction

The volume restriction Q serves to adapt the
air output capacity to the size of the actua-
tor.
The volume restriction is a screw restriction
(Table 1 on page 20) which is screwed in-
to the signal pressure output of the positioner
(or output of the pressure gauge bracket or
connecting plate).
Î SAMSONWe recommend using a screw
restriction.
For linear actuators with a transit
–
time <1 s (e.g. with an actuator area
smaller than 240 cm²),
For rotary actuators with a volume of
–
less than 300 cm³.
Î Actuators with a transit time ≥ 1 s do not
require the air flow rate to be restricted.
