Special features

• 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 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
o
Pre-Warning / Life Expired" is flashing.
If the electrode is in status "Tip life expired" the output
o
"GunX Pre-Warning / Life Expired" is set continuously.
At "Tip Dress Request" the output "GunX Tip Dress
o
Request" is flashing.
At "Tip Dress - Stop" the output "GunX Tip Dress Request"
o
is set continuously.
• Electrode tip dress:
In status "tip dress request" the output "GunX_Motor release" is set. Now a
weld program or a tip dress program can start:
If the input „Initiator-tip dress" is active, the control selects
o
automatically a tip dress program with the next start signal
independent of the program selection of the guns (program
4 with gun 1_Start or program 8 with gun 2_Start).
If the input „Initiator-tip dress" is not activ, the control takes
o
the program following program selection together with the
Start from the selected gun.
In status "Tip dress – Stop" the output "GunX_Motor release" is set. Now
only a tip dress program can get selected. The input "Initiator-tip dress"
must be set for running of the tip dress program. No other programs will be
start able. The other gun can not get started yet.
• Tip dress in status tip dress request
The tip dress program finishes following the programmed times or until the
according input "GunX Acknowledge Tip Dress" becomes active if the
acknowledge signal occurs earlier then the programmed time. Thus, this
acknowledge signal can finish the sequence of Tip dress before the
programmed end.
At the end of the sequence (regular or shortened) the output "GunX_
Solenoid Valve" is reset by the weld control. The output " GunX_Motor
Release" remains for further 1.5 sec before it will be reset. During this time
no new start is accepted from any gun.
