11.2.2 Overvoltage
The input voltage is over 290 volts. If the error condition persists for
longer than 15 seconds, the welding process will abort.
11.2.3 Resistance Error
The resistance of the connected fitting does not correspond to the value
previously read.
11.2.4 Frequency Error
The frequency of the input voltage is out of tolerance (42 Hz - 69 Hz).
11.2.5 Voltage Error
Check generator voltage and current. The output voltage does not cor-
respond to the value previously read; the welding unit has to be sent to
the manufacturer for check.
11.2.6 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.
11.2.7 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
cut-off 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 cur-
rent at start plus 15%.
11.2.8 Emergency Off
The welding process has been interrupted by pressing the STOP/RESET
key.
11.2.9 Heater Coil Error
The current value during welding differs by more than 15% from the
nominal value, indicating a short-circuit in the heater coil.
11.2.10 Power Supply Failure
The last welding is incomplete. The welding device was disconnected
from power supply voltage.
