When the fitting is connected, instead of the "No Contact"
message (see Display 2) the number of the next welding
report appears, e.g., "Prot. No.: 0015."
5.4 Reading the Fitting Code with a Handheld Scanner
Only the bar code on the tag sticking on the fitting to be
welded may be used. It is not acceptable to read the fitting
code tag of a fitting of a different kind if the intended
one is damaged or unreadable.
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. 9.2).
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 Direct Welding with the AutoWeld Feature
If two welding operations with electrofusion fittings with
the exact same welding parameters succeed each other, it
is not necessary to read a fitting bar code or enter welding
parameters manually. To start a welding operation that
is fully identical to the preceding one, it is sufficient to
use the AutoWeld feature, provided it was enabled in the
configuration menu (see Sect. 10.1). It is accessible from
thre quick selection screen opened from the "Enter Fitting
Code" screen with the ï arrow key (see Sect. 6.1). In this
screen, the selection cursor can be moved using the ñ and
ò; the selection is made with the START/SET key.
It is under the user's responsibility to rely on the
AutoWeld feature only when the preceding and
the planned welding operation and electrofusion
