Installing the external accessories
To protect the end positions against uncontrolled overrunning:
• Check whether proximity sensors are necessary (as safety limit switches or hardware limit
switches).
If you are using proximity switches (sensors):
• Use proximity sensors with normally-closed function.
These protect the ESBF from overrunning the end position if the proximity sensor cable is fractured.
• Use sensor rails or mounting kits ( www.festo.com/catalogue).
• Avoid external influence caused by magnetic or ferritic parts in the vicinity of the proximity sensors.
5.2 Installing circuitry
Note
Additional measures are necessary if used in safety relevant applications, e.g. in Europe
the standards listed under the EC machinery directive must be observed. Without addi-
tional measures in accordance with statutory minimum requirements, the product is not
suitable for use in safety-related sections of control systems.
