Manual EKS Electronic-Key Adapter Ethernet

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 release (switching contact A100.0 is opened).

Note: The switching contact A100.0 is only allowed to be set if

f the related 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 release by the EKS FSA and by the control and after operation of the

start button.
