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.
