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 read-
ing button. If the data are correctly read, the welding 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 or com-
puted from them. They are displayed before the ac-
Info
tual resistance of the electrofusion fitting is mea-
sured. This means that even when the showing ohm
value is o.k., a resistance error may still be detect-
ed (see Sect. 9.2). Only when the welding process
starts, the display shows the actual, measured weld-
ing 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 dis-
connected 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 configu-
ration menu (see Sect. 10.2), is requested by the sys-
Info
tem.
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 welding
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.
