10.1.7 Temperature Error

The ambient temperature measured is outside the operating range of
the welding unit, i.e., below – 20°C (– 4°F) or over + 60°C (+ 140°F).

10.1.8 Temperatur Sensor Defective

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

10.1.9 Clock Error

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

10.1.10 Unit to Service

The recommended next service date for the welding unit is overdue.
The service due message has to be acknowledged by pressing the
START/SET key. Send the welding unit to the manufacturer or an ap-
proved service point for service and check-up.

10.1.11 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.

10.1.12 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.

10.1.13 Download Cancelled

During data transfer or printing, an error condition occurred 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 toler-
ance.

10.2.4 Frequency Error

T h e f r e q u e n c y o f t h e i n p u t v o l t a g e i s o u t o f t o l e r a n c e
(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 welding unit has to be
sent to the manufacturer for check-up.
