Level Receiving Light Intensity Level Light Receiving Status Stable LED (green). and over Stable Incident. Unstable Incident Unstable Interruption OFF.8 and below Stable Interruption LED (yellow)/ Control Output Light Dark OFF OFF Sensitivity is set to the maximum (+) at the factory before shipment. When adjusting the sensitivity, use the screwdriver supplied with the photoelectric switch to turn the control as shown below, to a torque of.5 N m maximum. Step Photoelectric Switch Status Receiving light Through-beam, polarized reflective: No object detected Diffuse reflective, smallbeam reflective: Object detected Light is interrupted Through-beam, polarized reflective: Object detected Diffuse reflective, smallbeam reflective: No object detected 3 Sensitivity Control B B A A A C Adjusting Procedure Turn the control counter-clockwise to the mini mum ( ). Then turn clockwise (toward +) until the operation LED turns on (turns off with dark type) (point A). At interruption status, turn the control clock wise (toward +) from point A, until the operation LED turns on (turns off with dark type) (point B). If the operation LED does not turn on (turn off with dark type) even though the control has reached the maxi mum (+), set the maximum position (+) as point B. Set the middle point between point A and B as point C. & Optical Axis Alignment (Light ) Through-beam Fasten the temporarily. Place the projector to face the. Move the projector up, down, right and left to find the range where the operation LED turns on. Fasten the projector in the middle of the range. Next, move the up, down, right and left in the same manner and fasten in the middle of the range where the operation LED turns on. Make sure that stable LED turns on at stable incident and stable interruption. Polarized retro-reflective Install the reflector perpendicularly to the optical axis. Move the photoelectric switch up, down, right and left to find the range where the operation LED turns on. Fasten the switch in the middle of the range. Polarized retro-reflective model can be installed also by finding the position where the reflection of projected red light is most intense, while observing the reflection on the reflector from behind the switch. Make sure that stable LED turns on at stable incident and stable interruption. Diffuse-reflective/Small-beam reflective Place the photoelectric switch where the switch can detect the object. Move the switch up, down, right and left to find the range where the operation LED tuns on. Fasten the switch in the middle of the range. Make sure that stable LED turns on at stable incident and stable interruption. Because the light source element of small-beam reflective model is a red LED, visual inspection is possible as well. Adjustment of Sensing Range for Background Suppression (BGS) Model When adjusting the sensing range, follow the instruction below. Step Distance Control Adjusting Procedure A Install the photoelectric switch and the object firmly. Turn the control counterclockwise until the operation LED turns off (turns on with dark type). From this point, turn the con trol clockwise until the operation LED turns on (turns off with dark type) (point A). A Remove the object, and confirm that the operation LED turns off (turns on with dark type). Turn the control clockwise until the operation LED turns on (detecting the back ground) (turns off with dark type) (point B). (Note ) B A Set the middle point between point A and B as point C. (Note ) 3 B C Note : When the background is far off and not detected, turn the control 36, and set the point as point C. Note : Because the control is multi-turn, it may take more than one turn to move from point A to point B. Note 3: Turning the control clockwise lengthens the sensing dis tance. Note 4: Background suppression (BGS) model is not provided with a stable LED. LED (yellow) -L Sensitivity Adjustment Referring to the table at right, adjust the sensitivity of the photoelectric switch when necessary, in such cases as the throughbeam model is used to detect small or translucent objects or the reflective model is affected by background. The table explains the status of operation LED when the operation mode is set to light. After adjusting the sensitivity, make sure that stable LED turns on at stable incident and stable interruption. For detecting objects too small to turn on the stable LED, use an optional slit. (Note 3) Sensing Range Control (6-turn) (Note 4) Download catalogs and CAD from M-8

17 Miniature Photoelectric (Built-in Amplifier) & -L Operating Instructions Power Supply and Wiring Do not use the photoelectric switch at the transient status immediately after turning on the power (approx. ms, back ground suppression model: ms). When the load and switch use different power supplies, make sure to power up the switch first. Use a power supply with little noise and inrush current, and use the photoelectric switch within the rated voltage range. Make sure that ripple factor is within the allowable limit. Do not apply AC volt age, otherwise the switch may blow out or burn. When using a switching power supply, make sure to ground the FG (frame ground) terminal, otherwise high-frequency noise may affect the photoelectric switch. Turn power off before inserting/removing the connector on photoelectric switch. Make sure that excessive mechanical force is not applied to the connector. Connect the connector cable to a tight ening torque of.5 N m maximum. To ensure the degree of protection, use the applicable connector cable for the connector model. Connector cables are ordered separately. Avoid parallel wiring with high-voltage or power lines in the same conduit, otherwise noise may cause malfunction and damage. When wiring is long, use a separate conduit for wiring. Use a cable of.3 mm minimum core wires, then the cable can be extended up to m. Installation Installing the Photoelectric Switch Do not install the photoelectric switches in an area where the switches are subject to the following conditions, otherwise malfunction and damage may be caused. Inductive devices or heat source Extreme vibration or shock Large amount of dust Water, oil, chemicals Outdoor Make sure to prevent sunlight, fluorescent light, and especially the fluorescent light of inverters from entering the of the photoelectric switch directly. Keep the through-beam model away from intense extraneous light. Interference prevention allows two switches to be mounted in close proximity. However, the through-beam model is not equipped with interference prevention. Maintain appropriate dis tance between the switches referring to the lateral displacement characteristics. Because the photoelectric switches are IP67 waterproof, the can be exposed to water. However, wipe water drops and smears from the lens and slit using a soft cloth to make sure of the best detecting performance. Polycarbonate or acrylic resins are used for optical elements. Do not use ammonia or caustic soda for cleaning, otherwise optical elements will be dissolved. To remove dust and moisture build-up, use soft dry cloth. Tighten the mounting screws (M3) to a torque of.5 N m. Do not tighten the mounting screws excessively or hit the switch with a hammer, otherwise the protection degree cannot be maintained. Installing the Reflector Use M4 mounting screws for the IAC-R5 and IAC-R8 reflector, and M3 mount ing screws for the IAC-R6 reflector. Tighten the mounting screws to a tightening torque of.5 N m maximum. Mounting screws are not supplied with the switch. Use the M3 self-tapping screw, flat washer, and spring washer to tighten the IAC-R7 reflector to a torque of.5 to.6 N m. Optional reflector mounting bracket IAC-L is not supplied with mounting screws or nuts. IAC-L3 and IAC-L5 are supplied with mounting screws for mounting the reflector on the bracket. Reflector IAC-RS and IAC-RS can be installed directly on a flat surface using the adhesive tape attached to the back of the reflector. Before attaching the reflector, clean the board surface to ensure secure attachment. Installing the air blower mounting block SA9Z-A When installing the SA9Z-A on the photoelectric switch, use the attached M3 mounting screws and tighten to a torque of.5 N m maximum.
