F3S-B External Test > 15 ms If your application requires periodic testing more often than every 2 seconds an external control External test system is able to initiate an external test with the input (open) External test function. If a signal of 17 VDC to Vs is applied to the External test input at least 15 ms, Approx.
F3S-B 1-5 Detection zone Protective height The F3S-B can detect in the area indicated by “Protective height” in the figure below. The protective height is from “the Optical-axis line mark above the indicator area” to “the end of the yellow metal case”. Optical-axis line mark The center line for optical axes is indicated by the triangle mark.
F3S-B 1-6-2 Series connection types When your application requires an additional pro- tective zone, for example, to prevent someone from staying behind a primary detection zone, the F3S-B may be connected in series. The system consists of a master unit, a slave unit, and a series connection cable, type F39-JB1B (refer to “2-3-2 Wiring diagram”...

F3S-B Using EN 999 Formula (See Note 1) Safety distance is calculated based on the following equation. S = K x T + C S : Safety distance K : Intrusion speed into the detection zone T : Total response time for the machine and light curtain C : Additional distance calculated or defined based on the optical resolution of the light curtain When safety distance is not provided by European standards for individual machine, the distance can be calculated using EN 999.
Page 19
F3S-B Using ANSI/RIA R15.06 Formula (See Note 4) Safety distance is calculated based on the following equation when a person moves perpendicular to the detection zone of a light curtain. S = K x ( Ts + Tc + Tr ) + Dpf S : Safety Distance (mm) K : Speed constant of 1,600 mm/s (63 inches/s) minimum based on the movement being the hand/arm only and the body being stationary.
F3S-B 2-1-3 Distance from Reflective Surfaces WARNING Be sure to install the F3S-B to minimize the effects of reflection from reflective surfaces. Failure to do so will cause detection to fail and may result in serious injury. Install the F3S-B with minimum Distance D shown below from reflective surfaces (highly reflective sur- faces) like metal walls, floors, ceilings, and work pieces.

F3S-B MAINTENANCE Section 6 WARNING Do not use the F3S-B until the following inspections are completed. Failure to do so may result in loss of life or serious injury. Do not disassemble, repair or modify the F3S-B. Note: 1. For Safety, be sure to record and store inspection results. 2.
F3S-B TROUBLESHOOTING Section 8 The F3S-B runs internal self-tests after the power is turned ON and while the F3S-B is in normal opera- tion. The external test is also available. If a failure is detected, a corresponding flicker pattern is indicated by the red LED (OFF-state indicator) of the receiver.
