Description
• Via inputs and outputs of the welding controller, special, electrode-specific
information can be called up via a visualization unit and electrode maintenance
routines can be triggered.
• Electrode selection takes place via the "Electrode number Visu" input.
• The remaining parts of the respective electrode are output via these status
outputs (Visu).
• For values greater than 255, 255 is output.
• As soon as the outputs have been updated by the controller, the electrode
selection is mirrored to the outputs 160-168 "Echo electrode number (Visu)".
• The output of the remaining parts always follows the electrode selection.
• If the number of remaining parts changes (e.g. due to a welding process) with
a statically applied electrode number, these outputs are updated.
• Nothing changes at the "Echo electrode number Visu" outputs.
• Special, electrode-specific information can be called up via inputs and outputs
of the welding control system using a visualization unit, and electrode
maintenance routines can be triggered.
• Electrode selection is made via the "Electrode number Visu" input. Various
status outputs (Visu) are then updated.
• As soon as the statuses have been updated by the controller, the electrode
selection is mirrored to the "Echo electrode number Visu" outputs.
• If the status of a statically applied electrode number changes (e.g. due to a
welding process), the status outputs are updated, but nothing changes at the
"Echo electrode number Visu" outputs.
• When an electrode number Visu is applied and the corresponding input is
selected, the following electrode maintenance routines are executed:
Input "Acknowledgement tip dressing Visu" > Update status output >Output
–
"Echo acknowledgement tip dressing Visu".
Input "Change electrode acknowledgement Visu" > Update status output > "
–
Echo change electrode acknowledgement Visu" output
"Acknowledge dresser blade change Visu" input > Update Status output >
–
"Echo Acknowledge dresser blade change Visu" output
"Acknowledge gun change Visu" input > Update status output > " Echo
–
Acknowledge gun change Visu" output
• By recognition of the respective input signal the corresponding counters are
reset the status outputs are updated and an echo (these 4 bits) is output.
• These routines are exclusively operated, if the change of the respective inputs
takes place in the sequence-free time (before start or after resetting of the
progress contact) of the control.
