Figure 3-22. Interfacing supplemental safeguarding to prevent personnel from entering the hazardous area during the mute
NOTE: Depending on the application, the 3-beam EZ-SCREEN Grid
system shown typically would be configured for Trip Output
(Automatic Reset). The Muting Module’s manual reset would be
used to reset the system in the event of a stop command being
sent to the machine interface. This allows the EZ-SCREEN to be
interrupted as materials pass through during a muted condition,
without requiring a reset each time a blocked condition occurs.
3.5.6.5 SSI Supplemental Safety System Hookup
A variety of safety systems can be interfaced with the MSSI
and the SSI. Each safety application has a unique set of
application requirements. The user is responsible to ensure
proper installation and use, and that all relevant standards and
regulations are complied with. Figure 3-22 shows a generic
example of the flexibility of the SSI.
Entry/Exit Application with a Multiple-Beam Safety System
(Muted) and a Safety Mat System: see Appendix B for more
information. This application is widely used in a variety of
situations, including manufacturing cells, robotic cells, palletizers,
and de-stackers. One of the many requirements of this muting
application is that it must not be possible for personnel to walk
in front of, behind, or next to the muted object (e.g., the carrier
basket) without being detected and stopping the hazardous
motion.
Figure 3-22 shows how supplemental safeguarding (such as
a safety mat system or horizontal safety light screen) can be
interfaced to prevent personnel from entering the hazardous
area during a mute condition.
