Extruder control systems
HIGH Tech Extrusion group’s TEC
4s control system, which has already
delivered several orders in recent
months, can now also be ordered as
a retrofit kit exclusively for High Tech
Extrusion – Theysohn extruders.
The TEC 4s Extruder control system,
developed in cooperation with Siemens
using the latest state-of-the-art
technique, combines simple handling
and an efficient control system.
An operating terminal optimised for
heavy industrial conditions enables
a comfortable control of the whole
extrusion line in combination with the
modern HMI software. The 19" touch
screen provides easy operation with
large soft-keys and intuitive colour and
graphic design.
The core of the new Theysohn
extruder control system is a powerful,
fanless, maintenance-free industrial
PC. Communication between the TEC
4s and all drives, peripheral devices
and the whole downstream equipment
works through the efficient Profibus
bus system. Operational reliability and
short downtime are achieved by simple
wiring because of selected high-class
components, an analysis program and
remote maintenance via LAN and/or
WAN.
The company states that in 99
per cent of cases the customer can
maintain or exchange parts of the
system, saving the visit of a Theysohn
technician.
A few simple steps, without great
technical knowledge, are sufficient to
change frequency converters or CF-
cards, so production downtime can be
avoided and software updates can be
installed simply and quickly.
Following a check for compatibility of
main drive and dosing unit, the space
requirement for the new control cabinet
is assessed. The existing control
cabinet is replaced, together with the
installation of the 19" touch screen.
This solution provides an upgrade
to state-of-the-art management of the
entire extrusion line with its existing
components, while overall investment
remains manageable in comparison
with the acquisition of a brand new
extruder.
For reliability, the system features
two independent operating systems
(Windows XP Embedded and WinAC
RTX). In case of emergency, the main
motor can be started independently
from the PLC.
High Tech Extrusion, consisting of
the companies Theysohn, Technoplast,
Topf and Extruder-Komponenten
Salzgitter, is an ‘all in one’ provider
that has developed a unique series of
extrusion lines, tools and pipe heads.
The group operates internationally with
four production sites in Austria and
Germany as well as sales offices in
Russia and India.
