Obstruct defeating


Defeating guards and protective devices must be made more difficult.
The following measures may contribute:


  • Cover fixation of position switches
  • Use type 2 position switches (with separate actuator) with individual coded actuators, so that an actuator does only match to just one position switch at machine user’s site
  • Fix of position switch actuators in such a way that it is not possible to detach the fixation with readily available tools (pliers, screwdrivers, …) (Example: rebored screw
  • Use two position switches as break/make combination
