Special features
The welding controller features the following specifics:
• 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.
• Number of electrodes: 3 (electrode no.: 0 to electrode no.: 2)
• The "Stop circuit open / no 24 V" fault is automatically reset.
• The DC link voltage is always verified, the fault message is automatically
reset.
• Due to timer-internal routines, the minimal preweld/squeeze time is 16 ms.
• The function Initial dressing can be activated via timer parameter.
When this function is activated for a specific electrode a „Tip Dress Request"
will come immediately after the „Tip replaced" input signal.
• 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.
• %I Prewarning:
Phase value monitoring is carried out after each welding schedule. The mean
phase value is compared to electrode parameters
% limitation
o
%I prewarning
o
lower %I prewarning.
o
If one of the limits is exceeded, a warning is output. This warning will remain
active until the next tip dressing / tip change cycle or until the actual %I values
are reset at the user interface.
• The digital Input Transformer Temperature (X3,5) will monitored.
• Control preferable for hanging stations with 2 starts/2 electrodes and 9
programs in each gun with 2 outputs of end of sequence (EOS)
