5.3

Welding Process

The welding process is monitored for its entire duration, applying the welding parameters
computed for the electrofusion fitting.
5.4

End of Welding

The welding process was completed successfully if the actual welding time is 0 s (000 on the
display screen) the green LED (End) lights up at that point, and the audible signal beeps twice.
5.5

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.
An error has to be acknowledged by pressing the STOP key.
5.6

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.
5.7

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.

Self-Monitoring Functions Overview

System Error:
The welding unit must be disconnected immediately from the power supply
and the fitting. The auto-test has found an error in the system. The unit must
no longer be operated and has to be turned in for check and repair.
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.
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.
Low Voltage:
The input voltage is below 180 volts. Adjust generator output voltage.
Overvoltage:
The input voltage is above 280 volts. Adjust generator output voltage.
Temperature Error or Temperature Sensor Defective:
The measured ambient temperature is outside the operating range of the welding
unit, i.e., below – 5°C or over + 40°C.
If this error is displayed during the unit's auto-test, the temperature sensor is defective.
Frequency Error:
The frequency of the input voltage is out of tolerance (40 Hz - 70 Hz).
Low or Excess Current:
The message is displayed if the there is a momentary current failure or if the current
regulator is defective.
Emergency Off:
The welding process was interrupted by pressing the STOP key.
