10.1.13 Downloaded Cancelled

During data transfer or printing, an error condition oc-
curred which could not be cleared.
10.2

Errors During Welding

All errors that occur while welding is in progress are also
indicated by an audible alarm.

10.2.1 Low Voltage

The input voltage is below 175 volts. If the error condition
persists for longer than 15 seconds, the welding process
will be aborted. If the voltage goes down below 170 volts,
the welding process will abort immediately.

10.2.2 Overvoltage

The input voltage is over 290 volts. If the error condition
persists for longer than 15 seconds, the welding process
will be aborted.

10.2.3 Resistance Error

The resistance value of the connected fitting is out of the
read tolerance.

10.2.4 Frequency Error

The frequency of the input voltage is out of tolerance
(42 Hz - 69 Hz).

10.2.5 Voltage Error

Check generator voltage and current. The output voltage
does not correspond to the value previously read; the weld-
ing unit has to be sent to the manufacturer for check-up.

10.2.6 Low Current

The message is displayed if the there is a momentary cur-
rent failure or if the current decreases by more than 15%
per second for 3 seconds.

10.2.7 High 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%.
