5-3 Using Exact Channel Select with Floating Blanking
When both Exact Channel Select and Floating Blanking are selected, the floating channels are allowed to occur
anywhere within the detection zone (except for the beam nearest the cable), even within the area selected by
Exact Channel Select. In these areas, a channel that should normally be blocked is allowed to be clear.

WARNING
Using Exact Channel Select with Floating Blanking is an advanced feature. All situations which may occur to
the F3SL system detection zone must be carefully considered. The F3SL system may be less sensitive to
objects in the detection zone. The safety distance must be increased. Failure to do so may cause serious
injury.
To prevent a hand or other objects to enter the channel-selected part, provide a physical guard such as a
fence.
