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 unit (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.
