1 Safety and warning notes
This RESISTRON temperature controller is
manufactured according to DIN EN 61010-1. In the
course of its manufacture it passed through quality
assurance, whereby it was subjected to extensive
inspections and tests.
It left the factory in perfect condition.
The recommendations and warning notes contained in
these operating instructions must be complied with, in
order to guarantee safe operation.
The device can be operated within the limits indicated
in the "Technical Data" without impairing its operational
safety. Installation and maintenance may only be
performed by technically trained, skilled persons who
are familiar with the associated risks and warranty
provisions.
1.1 Use
RESISTRON temperature controllers may only be used
for heating and temperature control of heatsealing
bands which are expressly suitable for them, and
providing the regulations, notes and warnings
contained in these instructions are complied with.
In case of non-compliance or use contrary to
the intended purpose, there is a risk that
safety will be impaired or that the heatsealing band,
electrical wiring, transformer etc. will overheat.
Ensuring such compliance is the personal
responsibility of the user.
The RESISTRON temperature controller must be set
and coded according to the temperature coefficient of
the heatsealing band.
The use of incorrect alloys with a too low
temperature coefficient and incorrect coding
of the RESISTRON temperature controller lead to
uncontrolled heating and ultimately to burn-out of
the heatsealing band!
The heatsealing bands that were originally supplied
must be identified by detail specification, part number
or some other means that will assure that replacement
bands are identical.
1.3 Impulse transformer
A suitable impulse transformer is necessary to ensure
that the control loop functions perfectly. This
transformer must be designed according to VDE 0570/
EN 61558 (isolating transformer with reinforced
insulation) and have a one section bobbin. When the
impulse transformer is installed, suitable shock
protection must be provided in accordance with the
national installation regulations for electrical
equipment. In addition, water, cleaning solutions and
conductive fluids must be prevented from seeping into
the transformer.
Incorrect installation of the impulse
transformer impairs electrical safety.
1.2 Heatsealing band
1.4 Current transformer PEX-W2/-W3
A basic prerequisite for reliable and safe operation of
the system is the use of suitable heatsealing bands.
The resistance of the heatsealing band which
is used must have a positive minimum
temperature coefficient in order to guarantee
trouble-free operation of the RESISTRON
temperature controller.
The temperature coefficient must be specified as
follows:
e.g. Alloy-20: TCR = 1100 ppm/K
NOREX: TCR = 3500 ppm/K
The current transformer supplied with the RESISTRON
temperature controller is an integral part of the control
system.
Only the original ROPEX PEX-W2 or PEX-W3
current transformer may be used. Other
transformers may cause the equipment to
malfunction.
The current transformer may only be operated if it is
connected to the RESISTRON temperature controller
correctly (see section 9, "Startup and operation"). The
relevant safety instructions contained in section 8.3,
"Power supply", must be obeyed. External monitoring
modules can be used in order to additionally increase
RES-406 Page 3
Application
operating safety. They are not included in the scope of
supply of the standard control system and are
described in a separate document.
1.5 Line filter
The use of an original ROPEX line filter is mandatory in
order to comply with the standards and provisions
mentioned in section 1.7 "Standards / CE marking" on
page 4. This device must be installed and connected
according to the instructions contained in section 8.3,
"Power supply" as well as the separate documentation
enclosed with the line filter.
1.6 Warranty provisions
The statutory provisions for warranties apply for a
period of 12 months following the delivery date.
All devices are tested and calibrated in the factory.
Devices that have been damaged due to faulty
connections, dropping, electrical overloading, natural
wear, incorrect or negligent handling, chemical
influences or mechanical overloading as well as
devices that have been modified, relabeled or
otherwise altered by the customer, for example in an
attempt to repair them or install additional components,
are excluded from the warranty.
Warranty claims must be examined in the factory and
approved by ROPEX.
1.7 Standards / CE marking
The controller described here complies with the
following standards, provisions and directives:
DIN EN 61010-1
(VDE 0411-1)
DIN EN 60204-1 Electrical equipment of machines
EN 50081-1 EMC interference emissions
EN 50082-2 EMC interference immunity:
Compliance with these standards and provisions is only
guaranteed if original accessories and/or peripheral
components approved by ROPEX are used. If not, then
the equipment is operated on the user's own
responsibility.
The CE marking on the controller confirms that the
device itself complies with the above-mentioned
standards.
It does not imply, however, that the overall system also
fulfils these standards.
It is the responsibility of the machine manufacturer and
of the user to verify the completely installed, wired and
operationally ready system in the machine with regard
to its conformity with the safety provisions and the EMC
directive (see also section 8.3, "Power supply"). If
peripheral components (e.g. the transformer or the line
filter) from other manufacturers are used, no functional
guarantee can be provided by ROPEX.

2 Application
This RESISTRON temperature controller is an integral
part of the "Series 400", the outstanding feature of
which is its microprocessor technology. All
RESISTRON temperature controllers are used to
control the temperature of heating elements
(heatsealing bands, beaded bands, cutting wires,
heatsealing blades, solder elements etc.), as required
in a variety of heatsealing processes.
Page 4 RES-406
The controller is most commonly used for impulseheatsealing PE films in:
• Vertical and horizontal f/f/s machines
• Pouch, filling and sealing machines
• Film wrapping machines
• Pouch-making machines
• Group packaging machines
•etc.

The use of RESISTRON temperature controllers
results in:
• Repeatable quality of the heatseals under any
conditions
3 Principle of operation
The resistance of the heatsealing band, which is
temperature-sensitive, is monitored 50x per second
(60x at 60Hz) by measuring the current and voltage.
The temperature calculated with the help of these
measurements is displayed and compared with the set
point.
The primary voltage of the impulse transformer is
adjusted by phase-angle control, if the measured
values deviate from the set point. The resulting change
in the current through the heatsealing band leads to a
change in the band temperature and thus also its
resistance. This change is measured and evaluated by
the RESISTRON temperature controller.
The control loop is closed: ACTUAL temperature = SET
temperature. Even minute thermal loads on the
heatsealing band are detected and can be corrected
quickly and precisely.
A highly high response thermo-electric control loop is
formed which is highly accurate because purely
electrical variables are measured at a high sampling
rate. A high secondary current can be controlled
because power is controlled on the primary side of the
• Increased machine capacity
• Extended life of the heatsealing bands and teflon
coatings
• Simple operation and control of the sealing process
transformer. This allows optimum adaptation to the
load and to the required dynamic range despite the
exceptionally compact dimensions of the controller.
PLEASE NOTE!
RESISTRON temperature controllers play a significant
role in enhancing the performance of modern
machines. However, the full benefit can only be
obtained from the advanced technology offered by this
control system if all the system components, in other
words the heatsealing band, the impulse transformer,
the wiring, the timing signals and the controller itself,
are carefully compatible and interrelated.
We will be pleased to
contribute our many
years of experience
towards optimizing your
heatsealing system.

4 Description of the controller
Description of the controller
The microprocessor technology endows the
RESISTRON temperature controller RES-406 with
previously unattainable capabilities:
• Very simple operation thanks to AUTOCAL, the
automatic zero calibration function.
• Good dynamic response of the control system
thanks to AUTOTUNE, which adapts automatically
to the controlled system.
• High precision thanks to further improved control
accuracy and linearization of the heatsealing band
characteristic.
• High flexibility: The AUTORANGE function (as of
February 2006) covers a secondary voltage range
from 0.4V to 120 V and a current range from 30A to
500A.
• Automatic adjustment to the line frequency in the
range from 47 Hz to 63 Hz.
• Increased protection against dangerous conditions,
such as overheating of the heatsealing band.
The RESISTRON temperature controller RES-406 is
equipped with a PROFIBUS-DP interface. This
interface can be used to control all the controller
functions and interrogate controller information.
The ACTUAL temperature of the heatsealing band is
supplied to the PROFIBUS interface and to an analog
0 to 10V DC output. The real heatsealing band
temperature can thus be displayed on an external
temperature meter (e.g. ATR-x).
The RES-406 features an integrated fault diagnosis
function, which tests both the external system
(heatsealing band, wiring etc.) and the internal
electronics and outputs a selective error message in
case of a fault.
To increase operational safety and interference
immunity, all PROFIBUS signals are electrically
isolated from the controller and the heating circuit.
Either coding switches on the temperature controller
itself or the PROFIBUS interface can be used to adapt
to different heatsealing band alloys (Alloy-20, NOREX
etc.) and set to the required temperature range
(0…300°C, 0…500 °C etc.).
The compact design of the RESISTRON temperature
controller RES-406 and the plug-in connections make
this controller easy to install.
5 Accessories and modifications

These filters damp the reaction of the phase-angle
control on the line and protect the controller against line
disturbances.
The use of a suitable line filter is part of the
standards conformity and a prerequisite of
the CE mark.
ROPEX line filters are specially optimized for use in
RESISTRON control loops. Providing that they are
Large cross-section
installed and wired correctly, they guarantee
compliance with the EMC limit values.
You can find the exact specification of the line filter in
the ROPEX Application Report calculated for your
particular heatsealing application.

documentation.
It is permissible to supply several
RESISTRON control loops with a single line
filter, providing the total current does not exceed
the maximum current of the filter.
The wiring instructions contained in section 8.3 "Power
supply" on page 12 must be observed.
