Excerpt from the doc­u­ment:

This doc­u­ment has been developed for machine design­ers with­in man­u­fac­tur­ing plants and also to assist sys­tem integ­rat­ors and OEM‘s.

The spe­cific­a­tion cov­ers the imple­ment­a­tion from input devices through to final power ele­ments giv­ing examples util­iz­ing a safety relay based solu­tion and a con­fig­ur­able con­trol­ler solu­tion.

The dia­grams in this doc­u­ment should be used in con­junc­tion with the addi­tion­al recom­mend­a­tions detailed in:

  • EN 60204 – 1: Safety of Machinery – Elec­tric­al Equip­ment of Machines
  • ANSI B155.1 – Safety require­ments for pack­aging machinery (North Amer­ica ).
  • EN 415 – 4: Safety of pack­aging machines – Pal­let­izers and Depal­let­izers (Europe).

Note: Dif­fer­ent regions may have dif­fer­ent guidelines.

When imple­men­ted cor­rectly the cir­cuits described in this white­pa­per will com­ply with the require­ments for PLe (Per­form­ance Level) to (EN) ISO 13849- 1: 2015 and SIL3 (Safety Integ­rity Level) to IEC 62061: 2005.

A detailed descrip­tion of those stand­ards is provided in Safe­book 4, avail­able from Rock­well Auto­ma­tion.
