46/47 Bosch Rexroth AG
Features
7.1.10 With Q stop functionality
This output is set to 1 simultaneously with the output "Welding fault" if a Q-Stop-
error occurs. It is reset to 0 as soon as the fault will be reset.
7.1.11 Outputs Timer ready and welding fault are mirrored
The PRC outputs No. 5 "Timer ready" and No. 6 "Welding fault" outputs are
mirrored to the PRC outputs 100 and 101.
7.1.12 Visualization
Through the inputs and outputs of the weld timer and a visualization unit, special
electrode-specific information can be called up and electrode maintenance
routines can be activated.
An electrode selection is performed via the inputs "Electrode number
(visualization)" PRC inputs No. 128 - 135.
The information pertaining to the electrode selection is output through the
corresponding status outputs (visualization).
• The PRC outputs No. 120 - 127 show the remaining parts of the respective
electrode. In case of values higher than 255, the figure 255 is output.
• "Tip dress request visu"
• "Prewarning tip visu"
• "End of stepper visu"
• "Start-tip dress request visu"
• "Warning dresser blade wear visu"
• "End of stepper dresser blade wear visu"
• "Warning gun life visu"
• "End of stepper gun life visu"
As soon as the outputs have been updated by the timer, the electrode selection is
mirrored to the outputs "Echo electrode number (visualization)" PRC outputs No.
128 - 135. The status outputs always follow the electrode selection. If, in case of
an electrode number created statically, the status of this electrode number
changes (e.g. by a welding sequence), the outputs will be updated. Nothing will
change with regard to the "Echo electrode number (visualization)" outputs.
When an electrode number and the corresponding input are created, the following
electrode maintenance routines will be carried out:
• "Tips have been dressed (visualization)"
 Update status output  "Echo tips have been dressed (visualization)"
• "Tips have been changed (visualization)"
 Update status output  "Echo tips have been changed (visualization)"
• "Dresser blade has been changed (visualization)"
 Update status output  "Echo dresser blade has been changed
(visualization)"
• "Welding gun has been changed (visualization)"
 Update status output  "Echo welding gun has been changed
(visualization)"
When the respective input signal is detected, the corresponding counters will be
reset, the status outputs will be updated and an echo will be output. These
routines will be only be served if the changes in the respective inputs occur in the
sequence-free time (prior to start or after reset of weld complete) of the timer.
