The displayed circuit shows wiring errors in the area of the emergency stop unit and supply 

line. A possible short circuit on the primary side of the emergency stop switchgear (mass and 

24 Vdc) and a short circuit on the secondary side of the unit or within the wiring leads either 

directly or with closed contacts to a short circuit of the supply, whereby a series-connected 

24V fuse triggers.

Besides the two displayed applications with an emergency stop switchgear, other sensors 

(like door switches etc.) can be used similarly.
