Keep the operator’s guide handy and accessible to all users for possible referencing. Pass this guide on
to future users of the PIREG
®
-545.
All necessary settings are described in this operator’s guide. Should difficulties nevertheless arise during
commissioning or operation, please do not carry out any unauthorised manipulations. You could put your-
self and others at risk as well as jeopardize your warranty claim. In such cases, please contact us immedi-

Danger:
Indicates a hazard that could result in personal injury. Whenever this symbol is used,
the device description must be consulted, and the accompanying instructions must be observed
and followed in order to avoid hazards.
Danger:
Indicates a hazard due to electrical current. Failure to observe the safety instructions
may result in serious or fatal injuries.
Danger:
Indicates a hazard due to hot surfaces or burn up that could result in personal injury.
Note:
Indicates particularly important information which, if ignored, can lead to material damage,
for example.
1.3. General safety instructions
The safety instructions and warnings given in this description must be followed to guarantee safe
operation of the equipment. The equipment can be operated without impairing the operational
reliability if the conditions stated in the technical specifications are observed.
The equipment may only be installed and started-up by suitably trained personnel.
Maintenance and repair of the equipment may only be carried out by trained personnel, who are
familiar with the dangers and guarantee conditions.
1.4. Application
The PIREG
®
-545 resistance temperature controller may
only
be used for the heating and tem-
perature control of TOSS approved heat seal bands as via isolating transformers in accordance
with the regulations, notes and warnings contained in this description.
Non-observance of the instructions or incorrect use of the equipment can result in impairment of
the safety or overheating of the heat seal band, the electrical wiring or the transformer.
1.5. Heat Seal Bands and Genuine TOSS Alloy 20®
A basic precaution for the functioning and safe operation of the complete heat sealing system is the use of
suitable heat seal bands such as genuine TOSS Alloy 20 heat seal bands.
The positive temperature coefficient of the heat seal band must be equal or greater than the positive tem-
perature coefficient set on the PIREG
®
-545. This appropriate temperature coefficient of the heat seal band
must be set on the PIREG
®
-545 by means of the built-in display. The temperature coefficient of the heat
seal band must be positive over the entire temperature range.
Caution:
Using heat seal bands with too low a temperature coefficient or adjusting the controller
to a temperature coefficient that is too high, can result in uncontrolled overheating or the burning
out of the heat seal band.
Heat seal bands connected in parallel must be strictly symmetrical and performed in such a way that no
over-current arises if two heat seal bands on opposite sides should touch.
