OPERATIONAL SEQUENCE :
32. Set Micro ADM sensor “ PART ” input Bit O:1/1 .
33. Delay 80 msec for sensor I/O debounce time.
34. Test the sensor
“NEW PART” output I:1/0 for low
level indicating new part active. If High then clear
the sensor “
PART ” input Bit O:1/1. Then handle
sensor “Off-Line” error.
35. Start fixture weld cycle.
36. Wait for weld cycle complete.
37. Delay for 150 msec to allow sensor validation of
weld arc off.
38. Test the sensor “Fail” output I:1/2 if set handle
Weld Fault error condition.
39. Test the sensor “Pass” Output I:1/1 to validate
proper sensor operation. Only one output “Fail”
“Pass” will be set if neither output is set handle
sensor fault error.
Note: If the arc is active the sensor
“Pass” output will be low. Verify Arc
condition in error handler before sett
sensor fault error.
40. Test for last weld on part. If not last weld then
continue steps 1 – 9 until all welds are completed
before validating the sensor’s Part
“Pass” or “Fai
output.
41. Reset the sensor “Part” input O:1/1
42. Delay for 80 msec for I/O sensor debounce time
43. Test the sensor
“New Part” output I:1/0 to validate
part complete. If set handle sensor fault error.
44. Test the sensor part “Fail” output I:1/2 if set
handle Part Fault error condition.
45. Test the sensor part “Pass” Output I:1/1 to
validate proper sensor operation. Only one output
“Fail” or “Pass” will be set if neither output is set
handle sensor fault error.
Note: The actual Input/Output bits
assigned to the Micro ADM sensor w
depend on actual system integration to
PLC controller.
