2.2.2.5.3 Connection example with a safety controller
When using the B&R safety controller, the stop button can also be connected to this in addition to the enabling
control device.
The following example is intended as support for implementation in the end application and shows a wiring sug-
gestion for the enabling control device and stop button with a suitable safety monitoring device.

Connection (e.g. with X20SC0842 from B&R):
•
Px = Pulse x
•
SIx = Safe Input x
For the corresponding pinout of the safety monitoring devices, see the manufacturer documentation.
The following configurations must be made in the safety controller in order to achieve category 4 PL e:
•
Cross fault detection must be enabled.
•
A startup test must be performed. Each time the safety controller is switched on, a test must be performed
that checks the sensor in the low signal level direction (i.e. defined safe status), e.g. by actuating the enable
switch.
It is important to observe the configuration manual of the safety controller, the operating instructions of the safety
application programming tool and the functional safety manual.
The Mobile Panel, safety controller and all subsequent components must be taken into account when calculating
the entire "approval via enabling control device" safety function.
