2 Scope of application and technical data
2.1 Scope of application
The electro fusion control units of type
Polymatic / Polymatic Light
are exclusively for the electro
fusion of thermoplastic pipes (e.g. made of PE-HD, PE80. PE100 or PP) by use of electro fusion
fittings with an welding voltage lower than 48V . The control units are conform to the standard DVS
2208-1 as well as the ISO 12176-2, which refer to the standards applicable for the electro fusion fittings
to be used.
It is not allowed to use the electro fusion controllers, to which the present instruction manual refers to,
for an application not covered by the above stated terms. The manufacturer is not liable for the use of
the machine out of the scope of application.
2.2 Input of welding parameters
The electro fusion controllers of type
Polymatic / Polymatic Light
provide the following means for
entering the welding parameters:
BARCODE (ISO-TR 13950, Type 2/5i, 24 digits)
The barcode attached on the most electro fusion fittings in the market contains all necessary data for
processing them. After reading the barcode with the reading device, the process data is automatically
taken over by the control unit. The barcodes contains mainly the following data: Manufacturer, type,
diameter, fusion voltage, fusion time (with temperature correction, if applicable), resistance and
resistance tolerance.
FUSAMATIC-System:
By reading out the reference resistance in the connector pins of the FUSAMATIC-Fitting the control
unit automatically takes over the welding data of the fitting.
2.3 Range of fitting dimensions
For which range of fitting dimensions a electro fusion control unit can be used depends essentially on
the power consumption to the used fittings itself. Since the power consumption of the fittings are
different for different fitting manufacturers, a general statement concerning this point is hardly to make.
In case of doubt, each single case has to be checked separately. For electro fusion control units of the
type
Polymatic / Polymatic Light
the following general statement can be made, with the assumption,
that all welding processes were made one after the other, i.e. that the control unit is able to cool down
during the preparation time of the next fitting:
Polymatic:
Use for dimension
20-630mm
without any limit.
Polymatic Light:
Use for dimension
20-355mm
without any limit.
For larger diameters there must be provided longer off-times to ensure a cooling down of the control
unit (Error message “Device too hot”). Before processing fittings in this dimension range, you have to
check that the welding current of the fitting does not exceed the maximum output current of the control
unit.
All above made statements refer to an ambient temperature of 20°C.
