Intended use
CIRUS
®
Temperature Controllers may only be used for heating and temperature control of heatsealing elements
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 element, electrical wiring, transformer etc. will overheat. This is the personal responsibility of
the user.
2.3
Heating element
The temperature coefficient of a CIRUS
®
Temperature Controller is specially adapted to CIRUS heating elements.
The CIRUS
®
Temperature Controller is not allowed to be operated with any other heatsealing ele-
ments because they could be overheated and damaged beyond repair.
2.4
Impulse transformer
A suitable impulse transformer is necessary in order to guarantee trouble-free operation of the control loop. This
transformer must be designed according to EN 61558 (isolating transformer with reinforced insulation) and have
a one section bobbin. When the impulse transformer is installed, suitable touch protection must be provided in
accordance with the national installation regulations for electrical equipment. In addition to this, water, cleaning
solutions and conductive fluids must be prevented from seeping into the transformer.
Incorrect installation of the impulse transformer impairs electrical safety.
2.5
Current transformer PEX-W4/-W5
The current transformer supplied with the CIRUS
®
Temperature Controller is an integral part of the control system.
Only the original ROPEX PEX-W4 or PEX-W5 current transformer may be used. Other transformers may cause
the equipment to malfunction.
The current transformer may only be operated if it is correctly connected to the CIRUS
®
Temperature Controller
(see section "Startup and operation"). The relevant safety instructions contained in section "Power supply", must
