11.1.5 Overheated
The transformer temperature is too hot. Let the welding unit cool
down for about 1 hour.
11.1.6 System Error
CAUTION!
The welding unit has to be disconnected immediately from both the
power supply and the fitting. The auto-test has detected an error in
the system. The unit must no longer be operated and has to be sent
to an approved shop for check and repair.
11.1.7 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).
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 it, or
send the welding unit to the manufacturer for check and service.
11.1.10 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.
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. This error is also shown when too large a fitting
diameter (> 180 mm) was entered or read from a bar code (fitting ac-
tually too large or label tag of another fitting, not of the connected
one).
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 Download 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.
