11.1.8 Temperatur Sensor Defective

The ambient temperature sensor on the welding cable is damaged or
defective.

11.1.9 Clock Error

The internal system clock works improperly or is defective. Reset the clock
or send the welding unit to the manufacturer for check and service.

11.1.10 Next Service Due

The recommended next service date for your welding unit has passed.
The "Next Service Due" message has to be reacted to by pressing the
START key. Please send the welding unit to the manufacturer or an au-
thorized service point for service and check-up.

11.1.11 Input Error

A code entered is incorrect. With manual input enabled, no welding time
was set. An incorrect range was selected in the date setting.

11.1.12 Memory Full

The system memory is full of welding reports. Print off the reports in
memory or switch memory control off, using the operator card. The oldest
report will then be overwritten.

11.1.13 Printing interrupted

During data transfer or printing, an error condition occurred and 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 185 volts. The welding device triggers the
audible alarm. If the error condition persists for longer than 15 seconds,
the welding process will abort. If the voltage goes down below 170 volts,
the welding process will be aborted 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 abort.

11.2.3 Resistance Error

The resistance of the connected fitting does not correspond to the value
previously read.

11.2.4 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.

11.2.5 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.

11.2.6 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
