Unit-specific Information

8.1

Free Report Memory

Pressing and holding down the Ö arrow key while "Enter Fitting Code" is showing, causes the unit to dis-
play the number of reports that are currently free and can be used to save welding operations to memory.
8.2

Next Service Due

Pressing and holding down the Õ arrow key while "Enter Fitting Code" is showing, causes the unit to dis-
play the date when the next recommended service for the unit should be done.
If the recommended date has passed, a next service due message is displayed as soon as the unit is
plugged into the mains or generator power supply. This message has to be reacted to by pressing the
START key.
8.3

Measuring Resistance

When the START key was pressed, the resistance value of the fitting is measured and compared to the
value entered as part of the read fitting code. If the gap between the two values is smaller than the ac-
ceptable tolerance given in the code, the welding process starts. If the gap is greater than the preset tol-
erance, the welding unit aborts welding and displays a "Resistance Error" message. Furthermore, it dis-
plays the actual resistance value measured for the connected fitting.
8.4

Overheating Switch

The welding process is also aborted if the temperature of the transformer in the welding unit is too high.
The protective overheating circuit-breaker for the transformer stops the welding if the temperature reading
is too high and the remaining welding time is longer than 200 seconds. The display and the welding report
will show an "Overheated" message.
8.5

Power Supply Failure Indication

This indicates that the last welding aborted because of a power supply failure. The reason may be too
weak a generator or too long or too thin an extension cable, or a tripped protective fuse in the mounting
box.

Self-Monitoring Functions Overview

9.1

Errors During Data Input

9.1.1 Code Error
Erroneous input, poor code tag, error in code symbology or improper code reading.
9.1.2 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.
9.1.3 Low Voltage
The input voltage is below 175 volts. Adjust generator output voltage.
9.1.4 Overvoltage
The input voltage is over 290 volts. Decrease generator output voltage.
9.1.5 Overheated
The transformer temperature is too hot. Let the welding unit cool down for about 1 hour.
9.1.6 System Error
CAUTION!
