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.
6 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.
E00
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.
E01
No Contact:
There is no properly established electrical contact between the welding unit and the
fitting
E02
(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.
E03
Overvoltage:
The input voltage is above 280 volts. Adjust generator output voltage.
E04
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.
E05
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).
E06
Low or Excess Current:
The message is displayed if the there is a momentary current failure or if the current
regulator is defective.
E07
Emergency Off:
The welding process was interrupted by pressing the STOP key.
E08
Used Fitting Error:
After welding, the unit was not disconnected from the electrofusion fitting, and the user
tried to weld the same fitting a second time.
