Version December 2013 English

11.1.11 Input Error

A code that was entered is incorrect. At manual welding parameter input,
no welding time was entered. An incorrect value was selected in the date
setting.

11.1.12 Memory Full

The system memory is full of welding reports. Print or download the reports
in memory or switch memory control off. Without memory control, a new
report overwrites the oldest existing one.

11.1.13 Downloaded Cancelled

During data transfer or printing, an error condition occurred which could
not be cleared.

11.2 Errors During Welding

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

11.2.1 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.

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 be aborted.

11.2.3 Resistance Error

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

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 corre-
spond to the value previously read; the welding unit has to be sent to the
manufacturer for check-up.

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 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%.

11.2.8 Emergency Off

The welding process has been interrupted by pressing the STOP/RESET
key.

11.2.9 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.
