WARNING Do not use the F3S-AjP on a machine that cannot be stopped by electrical control in an emergency. J CALCULATING THE SAFETY DISTANCE J INSTALL CORRECTLY Correct Installation Dangerous machine parts can be reached only by passing through the F3S-AjP detection zone. ! WARNING Always maintain a safety distance for industrial machines of prEN999 between the F3S-AjP and dangerous machine parts. Serious injury may result if equipment does not stop before someone reaches a dangerous part. Safety distance (D) is calculated by the following equations: The minimum distance is 100 mm (3.94 in). D = 2,000 x T + In the case of D 500 mm (19.69 in) D = 1,600 x T + In the case of D > 500 mm (19.69 in) Where, D = Safety distance (mm) T = Response time (Stop time of the machine + Response time of the F3S-AjP) (sec) = 8 mm: 10 mm-pitch (Type F3S-Aj1P) 88 mm: 20 mm-pitch (Type F3S-Aj2P) * Emitter Optical axis Incorrect Installation Dangerous machine parts can be reached without passing through the F3S-AjP detection zone. A worker is between the F3S-AjP detection zone and dangerous machine parts. Receiver ! WARNING Be sure to install the F3S-AjP to minimize the effects of reflections from reflective surfaces. Failure to do so will cause detection to fail and may result in serious injury. Top View Reflective ceiling F3S-Aj2P Receiver Emitter Detection zone Emitter Reflective surface Receiver Reflective floor F3S-Aj1P Machine stop time (s) ! WARNING Install the F3S-AjP so that you must pass through the detection zone to reach the dangerous machine parts.

WARNING When using multiple sets of the F3S-AjP, install them so that mutual interference is not incurred by connecting them with sync line or using a barrier. Correct Configuration Receiver Emitter Emitter Receiver Correct Use Failure to observe the following items may result in F3S-AjP damage, deterioration, or improper operation. Installation Environment Do not install the F3S-AjP in the following environments: * * Interference from Another F3S-Aj jP Emitter Receiver Emitter Receiver Is not shorted. Does not use current higher than the rating. Is double insulated to protect the load from hazardous voltage levels when the load is a relay. * * * Areas exposed to intense interference light such as direct sunlight. Areas with high-humidity where condensation is likely to occur. Areas exposed to corrosive gases. Areas exposed vibration or shock levels higher than specification provisions. Areas exposed to contact with water. Do not use cellular phones or transceivers near the F3S-AjP. Wiring and Mounting Countermeasure to Prevent Interference Emitter Receiver Barrier Emitter * Receiver * J INSTALLATION CONDITIONS For your safety, always heed the following: DC Power Supply Units Must Satisfy All These Conditions * * * * * * * * * * * The power supply is connected to the F3S-AjP only and not to other devices or equipment. The power supply voltage is within the rating (24 VDC10%). Wiring is conducted only after confirming polarities of the power supply. The power supply conforms to EMC Directive (industrial environment). The power supply conforms to Low-voltage Directive. The power supply uses double or reinforced insulation between the primary and secondary circuits. The power supply automatically resets overcurrent protection characteristics (voltage drop). The power supply maintains an output holding time of at least 20 ms. When using a commercially available switching regulator, make sure FG (frame ground terminal) is connected to PE (protective earth). Faulty operation caused by switching noise may result if the terminal is not connected. Use one of the following wiring configurations to reduce noise terminal voltage to the primary side of the power supply: * Connect the 0V line to PE (protective earth). * Mount a capacitor with a minimum 47-nF capacity and minimum 630 V voltage rating between the 0V line and PE. Recommended Power Supplies: S82K, S8PS, S82J or S82H made by OMRON. * * * * * * * * * Be sure to turn OFF the power prior to wiring, or the diagnostic function may prevent the F3S-AjP from operating. Be sure to use shielded twisted-pair cables (cross-section at least 0.2 mm2 in diameter) when extending the sync line without using an F39-JAjA Series Connection Cable. Connect the shield to 0 V line. When using resin or other connectors in place of the unit's metal connector, make sure the conductor path in the connector is rated IP54 or higher. Check signal names for all terminals and wire terminals correctly. When using two or more F3S-AjP sets, be sure to connect a sync line and turn ON all power supplies at the same time (within 0.5 s). Never exceed specifications for the total number of sets and total number of the optical beams (up to 192 beams). The F3S-AjP will start operating in five seconds after the power is turned ON. Make sure that no faulty operation will occur in the control system. Once power is turned ON, do not turn it OFF again before the F3S-AjP becomes operational (LED indicator lights). Be sure to route F3S-AjP wires separated from high-potential power lines or to route through an exclusive conduit. Make sure the emitter and receiver are facing the proper direction. Use the interference light search function for no longer than 8 hours from startup, or the F3S-AjP will switch to OFF-hold condition (stop due to temporary failure). Use the emitter and receiver packed with the F3S-AjP and install them opposite to each other. 17 F3S-AjP F3S-Aj jP NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS.
