Dedicated Welding Unit Information
9.1
Displaying Characteristics of the Welding Unit
The key technical information on the welding unit itself is displayed by pressing the ð key at
the "Enter Fitting Code" screen. They are the software version, the serial number of the unit,
the date of the next scheduled maintenance, and the number of currently available, unused
reports. To quit this screen, press the STOP/RESET key.
If the scheduled service is overdue, a service due message appears on the screen as soon
as the unit is plugged into the mains or generator power supply. This message has to be
acknowledged by pressing START/SET.
9.2
Measuring Resistance
When the START/SET key was pressed to initiate a welding process, 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 acceptable tolerance given in the code,
the welding process starts. If the gap is greater than the preset tolerance, the welding unit
aborts welding and displays a "Resistance Error" message. Furthermore, it displays the actual
resistance value measured for the connected fitting.
The reason for a resistance error may be poorly contacting and/or worn connection terminals.
Therefore, if this error occurs, check them for proper fit and, if worn, replace them with new
ones.
9.3
Overheating Switch
The welding process aborts if the temperature of the transformer in the welding unit is too
high. The overheating circuit breaker for the transformer stops the welding if the temperature
reading is too high and the remaining welding time is longer than 800 seconds. The display
and the welding report will show an "Overheated" message.
9.4
Indication of Power Supply Failure at the Last Welding
The message "Power Supply Failure Last Welding" indicates that the previous 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 cut-out in the mounting box. The next welding operation is
still possible after acknowledging the message by pressing the STOP/RESET key.

Configuring the Welding Unit
With the operator identity card, the welding unit can be
reconfigured
.
Code" message appears on the screen. After the code was read
from the operator card, the selection menu in Display 12 shows.
At "Settings," the parameters related to the welding unit itself and
its operation can be set. At "Recording," the traceability data that
have to or need not be recorded and written into the reports can
be enabled or disabled. The desired sub-menu is selected using the ñ and òarrow keys.
Then to access that sub-menu, press the MENU key.
In both parts of the configuration menu, use the ñ , ò arrow keys to select the desired set-up
option. Use the ð arrow key to toggle between "on" and "off" for that set-up option.
If a "M" is shown next to a set-up option, this indicates that a sub-menu is accessible here by
pressing the MENU key.
Press the START/SET key to confirm the set-up and save it to memory.
10.1
Understanding the "Settings" Sub-menu
"Check Code Expiry on" means that the welder identification code
has to be current and not expired (default period of validity
2 years from code issuance), or the welding operation cannot
be started, "off," that the validity of the code is not checked at
all.
When the MENU key is pressed, the "Enter Menu
