2. Connecting the Electrofusion Fitting
Connect the connection terminals to the fitting and check for proper fit. The contact surfaces of the
connection terminals and the fitting have to be clean. Dirty terminals may lead to improper welding and
also to overheated and fused terminal plugs.
After the fitting was connected, the yellow LED (Fitting connected) lights up. At the same time, the screen
displays the welding time. The welding process can now be started by pressing the START key.
The welding time is counted down from about 80 s.
3. Welding Process
The welding process is monitored for its entire duration, applying the welding parameters computed for
the electrofusion fitting.
4. End of Welding
000
The welding process was completed successfully if the actual welding time is 0 s ("
" on the display
screen), the green LED (End) lights up at that point, and the audible signal beeps twice.
5. Aborted Welding
The welding process has caused errors if the red LED (Fault) is on and the audible signal beeps
intermittently. Additionally, an error code is displayed on the screen. See section 4 for more detail.
An error has to be acknowledged by pressing the STOP key.
6. Cooling Time
The cooling time as given in the fitting manufacturer's instructions has to be respected. Note that for that
time the pipe/fitting joint which is still warm must not be subjected to an external force.
7. Returning to the Start of Welding
After welding is finished, disconnecting the welded fitting from the welding unit will cause the unit to
return to the start of welding. An additional safety feature prevents a given electrofusion fitting from being
welded twice inadvertently: after a properly completed or an aborted welding operation, the welding unit
has to be disconnected from the fitting first, in order to be ready for the next welding.
4. Error Messages - Self-Monitoring Functions Overview
E01
1. Power Supply Failure (
)
The last welding is incomplete. The welding unit was disconnected from the power supply. This error has to
be acknowledged by pressing the STOP key.
E02
2. No Contact (
)
There is no properly established electrical contact between the welding unit and the fitting (check push-on
terminal on fitting), or the heater coil is defective.
E03
3. Low Voltage (
)
The input voltage is below 180 volts. Adjust generator output voltage.
