Self-Monitoring Functions Overview
11.1
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.
•
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.
•
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.
•
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.
•
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.
•
Overvoltage
The input voltage is over 290 volts. If the error condition persists for longer than 15 seconds, the
welding process will be aborted.
