Self-Monitoring Functions Overview

6.1

Errors During Data Input

6.1.1 No Contact

There is no properly established electric contact between the welding
unit and the fitting (check push-on connector on fitting), or the heater
coil is defective.

6.1.2 Low Voltage

The input voltage is below 190 volts. Adjust generator output voltage.

6.1.3 Overvoltage

The input voltage is over 285 volts. Decrease generator output voltage.

6.1.4 Overheated

The transformer temperature is too hot. Let the welding unit cool down
for about 1 hour.

6.1.5 System Error

CAUTION!
The welding unit has to be disconnected immediately from both the power
supply and the fitting. The auto-test has found an error in the system.
The unit must no longer be operated and has to be sent to an authorized
shop for check and repair.

6.1.6 Temperature Error

The ambient temperature measured is outside the operating range of the
welding unit, i.e., below -10°C or over +50°C.

6.1.7 Temperatur Sensor Defective

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

6.1.8 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 ser-
vice.

6.1.9 Service Due

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

6.1.10 Input Error

In the manual input, no welding time was set. An incorrect range was
selected in the date setting.

6.1.11 Memory Full

The system memory is full of reporting protocols. Print off the reports
in memory or switch memory control off. The oldest report will then be
overwritten.
6.2

Errors During Welding

All errors that occur while welding is in progress are also indicated by
an audible alarm.
