Using the arrow keys ñ and ò you can select "Enter Voltage/Time"
or "Enter Fitting Code" (i.e., the numbers that represent the code of
the fitting to be used). Confirm your selection by pressing the START/
SET key.
If this option was chosen in the manual parameter input menu, a
display like the one to the right appears on the screen. Use the al-
phanumeric keypad (see first Info in Sect. 4.1) to set the welding
voltage and the welding time, according to the fitting manufacturer's
instructions, then press the START/SET key to confirm your input. The
"Start ?" message displayed after the confirmation by START/SET (see
Display 32) indicates that the unit is ready for welding.
If this option was chosen in the manual parameter input menu, the
"Enter Fitting Code" display shows. The 24 characters of the fitting
code to be entered display as asterisks ( * ). Use the alphanumeric
keypad (see first Info in Sect. 4.1) to enter the code and press START/
SET to confirm your input and have it decoded. If the code entered
is not correct, a "Code Error" message appears; check the string of
numbers and correct as needed. If the code is correct, the decoded
data is displayed, and the "Start ?" message (see Display 32) indicates
that the unit is ready to start welding.
4.5.4 Starting the Welding Process
After the fitting bar code was read, the input of all trace-
ability data that were enabled in the configuration menu
(see Sect. 4.1.6, 4.2), is requested by the system.
Info
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 message "Pipe
treated?," which in turn requires a confirmation with the START/SET
key to start the welding proper.
4.5.5 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.
4.5.6 End of Welding
The welding process ends successfully if the actual welding time cor-
responds to the nominal welding time and the buzzer can be heard
twice.
4.5.7 Cooling Time
The cooling time as given in the fitting manufacturer's instructions has
to be respected. If the bar code provided by the fitting manufacturer
contains cooling time data, it will be displayed at the end of the weld-
ing process and will be counted down to zero. This countdown can
be acknowledged and canceled at any time by the STOP/RESET key.
However, note that for that time the pipe-fitting joint which is still
warm must not be subjected to an external force. No cooling time is
displayed if the fitting code does not contain any such information.
4.6 Aborted Welding Process
If an error condition is detected, the machine aborts the welding pro-
