The fllwing example cnfiguratins are intended t shw hw the Pepperl+Fuchs safety cntrller can be used t slve everyday safety applicatins. While each example has been designed with the utmst care users are reminded that they have t verify that the setups satisfy the rules and cnditins fr their industries and thse required by law and end user. Ultimately, we hpe t prvide a useful resurce fr all users f the SIMON+ cnfiguratin envirnment. Basic setup fr examples 1 7 In rder t try example cnfiguratins using the Pepperl+Fuchs safety cntrller, the fllwing electrical cnnectins need t be made. In additin t these cnnectins, the cnfiguratin sftware SIMON+ (VAZ-SW-SIMON+) must be installed n a Windws PC.

In this example, the setup f the magnetic dr switches has been changed t allw shrt term, single-cntact pening f up t 200 ms (this time is user selectable). This is frequently necessary n small access drs used t cver cnveyr systems in the fd and packaging industries. All ther settings are unchanged. Depressing the e-stps will turn OFF safe utput OSSD1. Once the e-stp has been released it can be reset. If drs are clsed, the safe utput OSSD1 will turn ON. Opening any ne f the drs will turn OFF safe utput OSSD1.

Example 6a Slenid-lcking dr (aut lcking) In this example, a slenid-lcking dr safety switch ( pwer t unlck design) and ne e-stp are used. The safe utput OSSD1 turns ON when the dr is clsed and latched (i.e., n pwer t the slenid) and the e-stp is released and reset. A nn-safe input is used t unlck the dr switch. Messaging utputs are used t indicate that the safe utput OSSD1 is OFF, the dr is clsed and lcked, the dr is unlcked and can be pened, and when the e-stp is ready t be reset.

Example 7 Safety circuit with EDM feedback This is a mdificatin f example 1. Safe utput OSSD1 is used t drive the slenid f a mtr starter. The feedback cntact n the mtr starter is mnitred. Depressing any ne f the e-stps will turn OFF safe utput OSSD1. Once all e-stps are in their released state, the reset can be activated and the safe utput OSSD1 will turn ON. EDM is based n the fllwing cnditins: 1. When the utput n the mtr starter is clsed, the feedback cntact must pen within a defined amunt f time 2. When the utput n the mtr starter is pened, the feedback cntact must be clsed within a defined amunt f time 3. The safety cntrller ges int the Errr Lck state if the feedback cntact des nt perate as described in steps 1 and 2. The safety cntrller must nw be reset using the SET buttn.
