•
Resistance Error
The resistance value of the connected fitting is out of the read tolerance.
•
Frequency Error
The frequency of the input voltage is out of tolerance (42 Hz - 69 Hz).
•
Voltage Error
Check generator voltage and current. The output voltage does not correspond to the value
previously read; the welding unit has to be sent to the manufacturer for check-up.
•
Low Current
The message is displayed if the there is a momentary current failure or if the current decreases by
more than 15% per second for 3 seconds.
•
Excess Current
The output current value is in excess; possible causes: short-circuit in the heater coil or the
welding cable. During the start stage the upper abort threshold equals 1.18 times the value at
start, in any other case the upper limit depends on the load value and is calculated as the current
at start plus 15%.
•
Emergency Off
The welding process has been interrupted by pressing the STOP/RESET key.
•
Heater Coil Error
The dynamic current value during welding differs by more than 15% from the required value,
indicating a short-circuit in the heater coil.
•
Power Supply Failure at Last Welding
The last welding is incomplete. The welding unit was disconnected from the power supply voltage
while it was in progress. To go on using the unit, this error has to be acknowledged by pressing
the STOP/RESET key (see also Sect. 9.4).
