11.5 Welding with SmartFuse
Attention!
The following description is based on the displays of an electrofusion control unit of type Monomatic
Data USB (Bluetooth).
11.5.1 Connection of a fitting
Attention!
The contact surfaces of the welding terminals and the pins of the fitting must be clean. Dirty or
coated terminals lead to overheating and scorching on the areas of contact inside the welding
terminals.
The welding terminals must be replaced as soon as they develop a coating on the contact surfaces
or a loss of contact force is noticeable.
Attention!
•
Pay attention to the installation instructions of the fitting, special instructions (ISO, CEN,
DVGW, DVS), European and national directives as well as to the instructions of the
manufacturers.
•
Dirty and/or damaged contacts in the terminals or on the fitting can be a reason for the
SmartFuse system to determine wrong welding parameters.
•
After the welding parameters have been automatically determined it is imperative that
you cross check the displayed parameters with the ones shown on the fitting to make
sure, that the correct welding parameters are used.

1
Before connecting a fitting, the display shows the main display:
Row 1 shows the message that a fitting must be connected.
2
A SmartFuse capable fitting is connected.
2.1
To weld with the SmartFuse system the red terminal must be connected to the contact of the fitting
that bears a red marking. After a fitting has been connected correctly in this manner, the
electrofusion control unit begins to determine the welding parameters based on the built-in resistor
in the contact of the fitting. During this procedure the display shows the following message:
Determination of the welding parameters
Row 1 shows that the SmartFuse resistor in the fitting is measured.
Row 2 shows the measured mains frequency, the mains voltage and the ambient temperature.
Row 3 shows the set date and time.
