This system also is no longer redundant and may result in a loss of safety if the second safety switch fails to switch when
needed.
The circuits in either scenario do not inherently comply with the safety standard requirements of detecting single faults and
preventing the next cycle. In multiple-guard systems using series-connected positive-opening safety switches, it is important
to periodically check the functional integrity of each interlocked guard individually.
Operators, maintenance personnel, and others associated with the operation of the machine must be trained to recognize
such failures and be instructed to correct them immediately.
Open and close each guard separately while verifying that the EZ-SCREEN SLS outputs operate correctly throughout the
check procedure. Follow each gate closure with a manual reset, if needed. If a contact set fails, the EZ-SCREEN SLS will not
enable its reset function. If the EZ-SCREEN SLS does not reset, a switch may have failed; that switch must be immediately
replaced.
This check must be performed and all faults must be cleared, at a minimum, during periodic checkouts. If the application can
not exclude these types of failures and such a failure could result in serious injury or death, then the safety switches must not
be connected in series.
