Special features

• Timer has been prepared for networking with an Ethernet-IP module (on-
board)
• Control is prepared for the control system PSQ6000 XQR.
Rewelds are not done in UIR-mode, but in KSR- or PHA-mode (regarding
measuring, regulation, supervision and stepper). KSR-supervision is further
active, if UI-supervision without UI-regulation is programmed.
• Outputs " UI Regulation active" and „UI monitoring active"
The outputs are set if the UI regulation resp. the UI monitoring is activated
in the current schedule. The outputs remain set until the next schedule is
started.
• With pressure output
• Without pressure feedback
• Timer preferably for suspended stations with 2 starts
• Number of electrodes: 86 (electrode no.: 0 to electrode no.:85)
However, electrode 0 is not assigned to a selectable program and should
therefore not be used. Electrode "0" is a normal electrode like all the others.
Acknowledgments for electrode "0" therefore apply to electrode "0" only
and not to the remaining electrodes at the same time.
• The stepper reference will be made as follows when the timer started or the
memory has been deleted:
Case 1: Input "Variant selection active" = 0:
o

Case 2: Input "Variant selection active" = 1:
o

• The time within the current has to exceed a minimum threshold is
adjustable. If this threshold is not exceeded on average, the sequence is
stopped and an error message occurs.
• Due to timer-internal routines, the minimal preweld/squeeze time is 16 ms.
• The "Stop circuit open / no 24 V" fault is automatically reset.
• The DC link voltage is always verified, the fault message is automatically
reset.
• The digital Input Transformer Temperature (X3,5) will monitored.
• The electrode maintenance concept takes the separate outputs for welding
gun no. 1 and welding gun no. 2 into account:
• In "Prewarning" condition the "Prewarning" output is set.
• In "Max. tip life /End of stepper" condition, the max. tip life/ output is set and
the Prewarning output flashes.
• In "Tip dress request" condition the Tip dress request output is set.
• In "Tip dress necessary" condition the Tip dress request output flashes.
