Section 1 Description 2) Manual reset mode ( Start / restart interlock) After the power is turned ON, or when at least one beam is interrupted, the light curtain enters the interlock condition. When the light curtain enters the interlock condition, it keeps the OSSD outputs in the OFF-state. Even if all beams become free, the OSSD outputs will not go to the ON-state.
Section 1 Description 1-2-3 Auxiliary Output (Non-safety output) The signal of this output is the reverse signal of the x 5 max. x 2 max. safety outputs (Dark-ON output). This output can be used for monitoring purposes by connecting it to a device such as a PLC.

Section 2 Wiring and Mounting Section 2 Wiring and Mounting 2-1 Installation Conditions 2-1-1 Detection Zone and Intrusion Path WARNING Do not use the F3SN-B on machines that cannot be stopped by electrical control in case of an emergency, such as a pressing machine with full-rotation clutch system.
Section 2 Wiring and Mounting 2-1-2 Safety Distance WARNING Always maintain a safe distance (S) between the F3SN-B and a hazardous part of a machine. Serious injury may result if the machine does not stop before someone reaches the hazardous part. The "Safety distance"...
Page 54
Section 2 Wiring and Mounting <Reference> Method for calculating the safety distance as provided by ANSI R15.06 (US) (for intrusion perpendicular to the detection zone) Safety distance (S) = Intrusion speed into the detection zone (K) x Response time (Ts + Tc + Tr) + Additional distance (Dpf) ...(4) Where: K = Intrusion speed: 1,600 mm/s or more Ts = Maximum time required for machine/equipment to stop (s)
Section 2 Wiring and Mounting 2-1-3 Distances from Reflective Surfaces WARNING Be sure to install the F3SN-B to minimize the effects of reflection from nearby surfaces. Failure to do so may cause detection to fail and may result in serious injury. Install the F3SN-B with minimum Distance D shown below from reflective surfaces (highly reflective surfaces) such as metal walls, floors, ceilings, and work pieces.
