9.2 Next Service Due
Pressing and holding down the
ð
arrow key causes the unit to display 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.
9.3 Inventory Number of the Unit
The welding unit allows its unique identification with the inventory number
it has in the company. The number can be entered into the unit via the
Set-up Menu (see sect. 10).
9.4 Checking the Scanner/Scanning Pen
The scanner/scanning pen can be checked for proper operation by reading
the remote-start bar code on the welding cable while “Enter Fitting Code”
is showing. The remote-start code then works as test code, and if the
scanner/scanning wand works properly, the welding unit will display “Test
Code Correct” on the screen and confirm this by an audible signal.
9.5 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 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.
9.6 Overheating Protection
The welding process aborts also if the temperature of the inverter in the
unit is too high. The overheating circuit-breaker for the inverter stops the
welding if the temperature is too high and the remaining welding time
exceeds 800 sec. Display and welding report indicate “Overheated”.
9.7 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.
10 Welding Unit Configuration
With the operator identity card, the welding unit can be reconfigured.
When the MENU key is pressed, the “Enter Operator Code” message
appears on the screen. After the operator code was read from the card
or entered manually, a selection menu as the one in Display 19 shows.
Use the
ñ
,
ò
arrow keys to select the desired configuration option.
Use the
ð
arrow key to toggle between „on“ and „off“ for that configura-
tion option.
If a “M” is shown next to a configuration option, this indicates that a sub-
menu is accessible here by pressing the MENU key.
Press the START key to confirm the set-up and save it to memory.
