7.1 Special features
The welding controller features the following specifics:
• Control preferable for hanging stations with 2 starts/2 electrodes and 4
programs each
• Weld Control is prepared for the control system PSQ6000 XQR.
• Control is prepared for a networking with Ethernet.
• The fault: "External 24V is missing" stop is automatically confirmed.
• A check of the pressure feedback at the end of the squeeze time is selectable.
• The mains voltage is always checked, the error message: Synchronization fault,
is self acknowledging.
• The gun is expected in retract open position when the weld control is switched
on.
At first the retract close signal is necessary to assure a defined gun position
and to avoid the program start with magnet valve closing in retract open
position of the gun which would be dangerous for the process.
• The program selection and the analog pressure output will be updated as soon
as there is a change in one of the inputs "Gun X_Program_Y", "Initiator Tip
dress" or "Individual Tip dress" , not only with the next start of a weld schedule.
The program selection is related to the gun which was last started.
• The gun delay times T_delay and T_delay_schedule, which are mentioned in
the folowing diagrams are programable.
• When Lamp test is selected, Lamp test activates the following outputs:
- Timer control ready
- - Timer control fault
- - Weld fault
- - Tip dress request 1
- - Tip dress request 2
- - Tip life Warning/Exp 1
- - Tip life Warning/Exp 2
- - UI-regulation active
• With cooling fan supply on X4/13-14
- "Fan On ", if cooler temperature is > = 55 º C
- "Fan Off ", if cooler temperature is < = 40 º C
7.1.1 Electrode care concept
The electrode care concept has got separate in-and outputs for electrodes No. 1
and electrodes No. 2.
If the electrode is in status "pre warning" the output "GunX Pre-Warning / Life
Expired" is flashing.
If the electrode is in status "Tip life expired" the output "GunX Pre-Warning / Life
Expired" is set continuously.
At "Tip Dress Request" the output "GunX Tip Dress Request" is flashing.
At "Tip Dress - Stop" the output "GunX Tip Dress Request" is set continuously.
