6.0 Micro ADM™ Remote I/O User Interface
6.1 GENERAL DESCRIPTION
The Micro ADM™ AAD interface is comprised of three 24 VDC inputs and three
24 VDC sourcing outputs. INP1
“Learn” input is used to invoke a learn mode for
the Micro ADM™. This input will allow the Micro ADM™ to monitor multiple parts
and to establish the necessary control limits that will be used to verify production
parts. The Micro ADM™ uses Accumulated Arc Density (AAD) to validate the
welds and assure conformance to the base-line sampled group of parts.
The INP2 “Part” input is configured to allow the user to indicate when a part is
being welded. This input must be asserted during the complete part cycle. The
Micro ADM™ uses this input to establish when a new part is being welded.
When the input is cleared the Micro ADM™ will perform a final analysis of all the
welds made and set the pass/fail Part output signals. The pass-fail outputs will
be set based on weld volume, weld counts and work-applied calculations.
The optional INP3 “Group B” input can be used to separate two weld groups
within a single Part. When invoked the Group input signals the completion of the
“Group A” welds and the start of the “Group B” welds. This input must be
asserted during the complete
“Group B” weld cycle. The Micro ADM™ uses this
input to establish when the first “Group A” welds have been completed and the
beginning of the “Group B” welds. When the input is asserted the Micro ADM™
will perform a final analysis of the entire first
“Group A” welds and will assert the
pass/fail Part output signals. The “Group A” pass-fail outputs will be set based
on total weld volume, weld counts and total work applied for all of the Group A
welds. When the “
New Part ” and the “Group B” input are cleared, at the end of
the “ Group B ” welds, then pass-fail output will be asserted for the second “ Group
B ” welds. The “Group B” pass-fail outputs will be set based on total weld volume;
weld counts and total work applied for only the Group B welds. When using the
“Group B” input the Micro ADM™ will generate automatic process control limits
for all welds made for the first Group A welds and the second Group B welds.
This input is used during the learn mode to build the control limits and weld
counts for each weld group.
The three output signals are used to indicate the operational and pass-fail status
for each weld and part. CR1 is the
“Part Complete” output and is asserted when
the user INP2 has been cleared and the Micro ADM™ has completed its Part
evaluation routines. When INP2 is asserted the
“Part Complete” (CR1) output is
cleared. This output can be used to validate operation of the Micro ADM™ and
to determine Part or Weld faults. When the
“Part Complete” (CR1) output is
cleared then any faults indicated will be based on individual welds. When the
“Part Complete” (CR1) is asserted then the Fault indication will be the result of a
Part totalize error. The second output CR2 provides a “No Fault” output. This
output will be asserted when the each weld has terminated and no faults were
