9 Self-Monitoring Functions Overview
9.1 Errors During Data Input
• Code Error
An erroneous input has occurred, a code tag is poor or has an error in code symbology or code
reading was improper.
• No Contact
There is no properly established electric contact between the welding unit and the fitting (check
push-on terminal on fitting), or the heater coil is defective.
• Low Voltage
The input voltage is below 175 volts. Adjust generator output voltage.
• Overvoltage
The input voltage is over 290 volts. Decrease generator output voltage.
• Overheated
The transformer temperature is too hot. Let the welding unit cool down for about 1 hour.
• 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.
• 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).
• Temperature Sensor Defective
The ambient temperature sensor on the welding cable is damaged or defective.
• 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.
• 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 approved service point for service and check-up.
