This video gives basic information on Using the Trailing Edge One-Shot on Power Flow Contact in the Do-more Designer software. It presents information that is commonly missed by users. This WILL NOT be a complete tutorial for the instruction but rather a supplement to the help file and customer experience.
This contact will allow power flow, for one complete PLC scan, when the input to the contact transitions from On to OFF. Since this action happens in one PLC scan, it is unlikely you will see status indication in the programming software. Use an increment or counter instruction to verify the contact. This contact must be in series with no parallel contact above or below it.
