The safety relay is de-energized without a time delay (stop category 0) and the machine movement is stopped if

f the Electronic-Key is removed or

f the machine control system cancels the enable state (switching contact A100.0 is opened).

Note: The switching contact A100.0 may be set only if

f the corresponding Electronic-Key is inserted and

f a suitable operating mode is selected.

6.4.2.2 Feedback loop

The safety relay can be started only with the feedback loop closed. A welded contactor contact in the enable

path will thus be detected when a start request is made and a start is then prevented. The power contactor must

have positively driven contacts.

6.4.2.3 Start

The safety relay start takes place after enabling by the EKS FSA and by the control system and after operation

of the start button.
