After the acknowledge signal and after reset of the output "GunX_Motor
Release" the control resets the output "GunX_ Tip Dress Request". Now,
the internal spot and tip dress counter will be actualized and the normal
sequence is available again.
• 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.
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). After a tip
dress program was started, the tip dress acknowledgement is accepted only
once.
Electrode Tip change:
•
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.
• Change outside of the status „prewarning" or „end of stepper"
Via the input „Individual Tip Change" a change of the electrode is possible
anytime, it means also outside of a prewarning or end of stepper is
possible, independent of the electrode status.
Start Tipp dress:
•
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.
