Appendix D
Checklists for GuardLogix Safety
Applications
Introduction
The checklists in this appendix are required for planning,
programming, and start up of a SIL 3-certified GuardLogix application.
They may be used as planning guides as well as during functional
verification testing. If used as planning guides, the checklists can be
saved as a record of the plan.
The checklists on the following pages provide a sample of safety
considerations and are not intended to be a complete list of items to
verify. Your particular safety application may have additional safety
requirements, for which we have provided space in the checklists.
