Prerequisites for use:
• Only those objects which actually protrude into or pass through the safety field during operation may be
used for the configuration.
• Testing must be performed in order to determine whether or not floating blanking can be used, whereby
all possible object arrangements (practical experience) have to be tested.
• The “restart inhibit” and “contactor monitoring” functions can be activated as required in the auto-floating
blanking operating mode.
• A warning lamp must be additionally connected.
• Safety clearance is influenced by auto-floating blanking.
• The operation mode „Auto Floating Blanking“ can only be parameterized via the serial interface. (view
operating instruction B-wsafe)
5.4.3.2 Auto Floating Blanking Procedure
