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. To prevent a hand or other objects to enter the channel-selected part, provide a physical guard such as a fence. 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. 9 5 Detection Options 5-4 Activating and Programming Exact Channel Select 5-3-1 The Effect of Exact Channel Select and Floating Blanking on Minimum Object Resolution When Exact Channel Select and/or Floating Blanking is active, the safety distance is affected. Exact Channel Select and Floating Blanking desensitize the light curtain and increase the size of the minimum object detected. The increase is equal to the channel spacing distance for each channel that is disabled. · A F3SL system with one channel disabled has a minimum object sensitivity of: 30mm + 22mm =52mm (2. 05 inches). · A F3SL system with two channel disabled has a minimum object sensitivity of: 30mm + 22mm + 22mm =74mm (2. 91 inches). If the size of the object detected by the F3SL system increases, the minimum safe distance must increase. Use the minimum object sensitivity given in to determine the new figure to use when computing the safety distance.

Set these switches before mounting the receiver. WARNING Disconnect power before removing end cap. To program an ECS pattern, the F3SL system must be in the machine stop state. [. . . ] Inspect the electrical connections between the guarded machine's control system and the F3SL system.
