General information
This RESISTRON
®
temperature controller is manufactured according to EN 61010-1. In the course of its manu-
facture it passed through quality assurance, whereby it was subjected to extensive inspections and tests. As a
result of this, the product left our factory in perfect condition.
Please carefully read through the operating manual before using the RESISTRON
®
temperature controller. Keep
the operating manual for later reference and make sure that information and functions important for the user are
available.
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.

Intended use
RESISTRON
®
temperature controllers may only be used for heating and temperature control of heatsealing bands
which are expressly approved for them, and providing the regulations, notes and warnings contained in these
instructions are observed.
In case of non-observance 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. This is the personal responsibility of the
user.
1.3
Heatsealing band
The use of suitable heatsealing bands is a basic prerequisite for reliable and safe operation of the system.
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 A20:
TCR = 1100 ppm/K
LEX3500:
TCR = 3500 ppm/K
Vacodil:
TCR = 1100 ppm/K
The RESISTRON
®
temperature controller must be set and coded according to the temperature coefficient of the
heatsealing band.
The temperature coefficient must be taken from the ROPEX application report and must be set accordingly.
The use of incorrect alloys with a too low temperature coefficient and incorrect coding of the
RESISTRON
®
temperature controller leads to uncontrolled heating of the heatsealing band, which
will ultimately burn out!
The original heatsealing bands must be clearly identified by means of suitable markings as well as the connector
geometry, length, or other means to ensure that replacement bands are identical.
