IP-215A/IP-217A FINE SPOT WELDING POWER SUPPLIES
993-603 REV A: October, 1996
APPENDIX E: ALARM MESSAGE LIST
Voltage Upper Limit Exceeded.
When the weld is completed, the
measured vol-tage value between the
electrodes has gone above the voltage
monitor upper limit setting.
MR = 0:
END signal is output
at I/O connector
(refer to Appendix
B). Next weld can
begin.
MR = 1:
END signal is not
output at I/O
connector. Next weld
cannot begin.
Power Lower Limit Exceeeded.
When the weld is completed, the
measured power value has gone below
the power monitor lower limit setting.
MR = 0:
END signal is output
at I/O connector
(refer to Appendix
B). Next weld can
begin.
MR = 1:
END signal is not
output at I/O
connector. Next weld
cannot begin.
Power Upper Limit Exceeded. When
the weld is completed, the measured
power value has gone above the power
monitor upper limit setting.
MR = 0:
END signal is output
at I/O connector
(refer to Appendix
B). Next weld can
begin.
MR = 1:
END signal is not
output at I/O
connector. Next weld
cannot begin.
Error Reset:
MR = 0:
Next START signal
auto-matically clears
error con-dition.
MR = 1:
Close RESET input
signal at I/O
connector.
Remedies: Check for problems in the
work pieces and the weld head.
Error Reset:
MR = 0:
Next START signal
auto-matically clears
error con-dition.
MR = 1:
Close RESET input
signal at I/O
connector.
Remedies: Check for problems in the
welding cables, voltage sense cables,
work pieces, the weld head, and the AC
input voltage source.
Error Reset:
MR = 0:
Next START signal
auto-matically clears
error con-dition.
MR = 1:
Close RESET input
signal at I/O
connector.
Remedies: Check for problems in the
work pieces and the weld head.
