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 1.6 "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
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.
1.7
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.

Application
If the RESISTRON controller circuit is analyzed in
detail, it is clear that a whole series of hardware faults
could conceivably result in dangerous conditions, for
instance because they cause the heatsealing band to
overheat but are not detected by the standard alarm
function. Even if most of these hardware faults are very
unlikely to occur, such failures can never be completely
ruled out.
A redundant measuring system, the RESM-5, is
therefore essential to monitor the complete controller,
including the current transformer.
The RESISTRON monitoring device RESM-5 is
connected to an existing RESISTRON control system
