Read the fitting code by holding the scanner in front of
the bar code at a distance of 5 to 10 cm (2 to 4 inches),
where the red line indicates the reading area. Then push
the reading button. If the data are correctly read, the weld-
ing unit confirms this by an audible signal and displays the
decoded data on the screen (see Display 4).
The displayed values are the nominal welding pa-
rameters contained in the fitting bar code. They
are displayed before the actual resistance of the
Info
electrofusion fitting is measured. This means that
even when the showing ohm value is o.k., a resis-
tance error may still be detected (see Sect. 8.2).
Only when the welding process starts, the display
shows the actual, measured welding parameters.
The "Start ?" message means that the unit is ready to start
the welding process. Check the read data and if you see
that they are erroneous, delete them by pressing the STOP/
RESET key. The read data are also deleted if the welding
unit is disconnected from the fitting.
5.5

Starting the Welding Process

After the fitting bar code was read, the input of
all traceability data that were enabled in the con-
figuration menu (see Sect. 9.2), is requested by the
Info
system.
After reading or entering the fitting code, the welding
process can be started using the START/SET key, when the
"Start ?" message is displayed and there is no indication
of a problem.
Pressing the START/SET key will trigger a confirmation mes-
sage "Pipe treated?," which in turn requires a confirmation
with the START/SET key to start the welding proper.
5.6

Welding Process

The welding process is monitored for its entire duration
applying the welding parameters contained in the fitting
code. The welding voltage, the resistance, and the weld-
ing current are displayed in the lower line of the screen.
5.7

End of Welding

The welding process ends successfully if the actual weld-
ing time corresponds to the nominal welding time and the
buzzer can be heard twice.
