Self-Monitoring Functions Overview
5.1
System Error
CAUTION!
The welding unit has to 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.
5.2
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.
5.3
No Contact
There is no properly established electric contact between the welding unit
and the fitting (check push-on terminal on fitting), or the heater coil is
defective.
5.4
Low Voltage
The input voltage is below 180 V. Adjust generator output voltage.
5.5
Overvoltage
The input voltage is above 280 V. Adjust generator output voltage.
5.6
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 sen-
sor is defective.
5.7
Frequency Error
The frequency of the input voltage is out of tolerance (40 Hz - 70 Hz).
5.8
Low or Excess Current
The message is displayed if the there is a momentary current failure or if
the current regulator is defective.
5.9
Emergency Off
The welding process has been interrupted by pressing the STOP key.
