6.3 SETTING PROCESS CONTROL LIMITS
The Micro ADM™ has a learn mode that is used to establish the Part and weld
process control limits. This mode is used to calculate the required AAD limits
and to establish the base-line weld data limits. The user must first validate the
process parameters and be assured that the parts are conforming to applicable
codes and design specification.
To activate the learn mode assert the INP 1 input. This input is a 24 VDC input
and is an active high input. To activate the learn mode assert and maintain the
INP1 input during the complete learn cycle. Weld 10 parts using the normal
interface sequence. If the optional
“INP3 - Part B” input is used, it should be
asserted at the end of Part A welds and cleared when the “INP2-New Part” input
is cleared, after completing the Part B welds.
The Micro ADM™ will assert the “CR2-No Fault” and “CR3-Fault” output will be
cleared to indicate the learn mode. The “CR2-No Fault” output will be cleared
during the arc on period then asserted when the arc is off. After processing 10
parts the Micro ADM™ will assert and hold the
“CR2-No Fault” which will indicate
completion of the Learn cycle. The user should than clear the “INP1-Learn” input.
To terminate a learn cycle before completing the 10 parts the user will clear the
“INP1-Learn” Input. The “CR3-Fault” output will be asserted indicating a learn
mode fail.
Warning: Clearing the learn mode prior to completing the 10 welds will result in all
process limits being reset and inhibiting further testing until the part is re-
learned.
