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:
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 con-
trol the temperature of heating elements (heatsealing
bands, beaded bands, cutting wires, heatsealing
blades, solder elements etc.), as required in a variety of
heatsealing processes.
The controller is most commonly used for impulse-
heatsealing PE and PP films in:
• Vertical and horizontal f/f/s machines
• Pouch, filling and sealing machines
• Film wrapping machines
• Pouch-making machines
• Group packaging machines
• L-sealers
