Features
Electrode Tip change:
Start Tipp dress:
 Tip dress outside status tip dress request
The tip dress is every time possible via the input „Individual Tip dress" – also
out of the tip dress request mode of the control independent of the status of the
electrodes.
With the input „Individual Tip dress" active the control sets both outputs "Gun
X_ Tip Dress Request" continuously high and the weld control is in status "Tip –
dress stop".
The outputs "GunX_Motor Release" are also set. With the next start at a gun
the gun the specific tip dress program will run automatically. After the tip dress
procedure the acknowledge signal "GunX Acknowledge Tip Dress" is necessary
for positive confirmation and reset of the internal spot and tip dress counter. If
there is no positive confirmation the counter status of the according guns
remain with the actual values. Without the positive confirmation the „Individual
Tip dress" procedure does not effect the electrode status independent of the tip
dress actions.
With firmware-Version -102: The input "GunX Acknowledge Tip Dress" results in a
reset of the counters and the status of the electrode, if the last started program
with this according electrode was the tip dress program (gun 1: prog. 4, gun 2:
Prog. 8).
The output "GunX_ Tip life Warning/Exp" flashes if the wear counter is at the end
after the last tip dress step of the electrodes entering the prewarning level. If the
welding goes on the wear counter gets to the programmed max. value and the
output "GunX_ Tip life Warning/Exp" is set continuously.
In status prewarning or latest in status max. tip life the electrode tips must be
changed.
The executed tip change is acknowledged by the input "GunX Acknowledge Tip
Change". With this acknowledge signal the internal spot and tip dress counter of
the control will be reset.
The input "GunX Acknowledge Tip Change" is only accepted if the according
electrode is in status "prewarning" or "max. tip life". Otherwise the acknowledge
signal is without functionality.
If the start tip dress for the according electrode is activ the control sets the output
"GunX_ Tip Dress Request" continuously after successful tip change procedure.
The according electrode has to be tip-dressed with the next schedule. The tip
dress procedure is following the normal tip dress routine.
After successful start tip dress the tip dress counter is increased and the output
"GunX_ Tip Dress Request" is reset. Now the tip dress counter is at "1" and the
wear counter is at "0" in the control.
