If the LIGHT indicator LED does not turn ON at this position without surroundings towards detection direction, then recognize this position as "FAR" one. If the LIGHT indicator LED turns ON at this position detecting surroundings, turn the DISTANCE adjuster slowly counterclockwise to find a FAR position where the LIGHT indicator LED turns OFF. 3) Place a target at the detection position and set the DISTANCE adjuster to its minimum setting NEAR and slowly turn it clockwise and note the LIGHT indicator LED turns ON. The minimum position at which the LIGHT indicator LED turns ON is the NEAR position. 4) Set the DISTANCE adjuster to the middle of the two positions found in 2) and 3) above. 5) Fasten the photoelectric sensor. Mount securely so that the photoelectric sensor is not shifted from alignment by vibrations or impact. Notes: 1. If the ADJUST indicator LED does not turn ON in step 4), or if such a operation range acquainted by above 2) or 3) is less than 2 graduations, either change the position of the detection surface and repeat steps 1) to 4), or adjust external factors such as ambient temperature variations, position of target, etc. 100 Retroreflective type STAB indicator LED LIGHT-ON/DARK-ON selector switch SENSITIVITY adjuster OPE indicator LED Thru-beam type (receiver) STAB indicator LED LIGHT-ON/DARK-ON selector switch SENSITIVITY adjuster OPE indicator LED 2. The detection distance varies only slightly with the color of the target. However, if the target has an extremely low reflection factor (dull black rubber), detection may not be possible, or if the target has an extremely high reflection factor (mirrors, glass, glossy paper and other specular reflection targets), adjustment of the detection distance may not be possible. Use the actual target to check operation. 3. Please be careful not to apply excessive torque to the DISTANCE adjuster and the LIGHT-ON/DARK-ON selector switch. Sensitivity adjustment for Diffuse reflective type 1) Facing the detection face in the detection direction, temporarily fasten it. 2) Set the SENSITIVITY adjuster to its maximum position (MAX.). If the OPE. indicator LED does not turn ON at this position without surroundings towards detection direction, then recognize this position as "MAX.'' one. If the OPE. indicator LED turns ON at this position detecting surroundings, turn the SENSITIVITY adjuster slowly counterclockwise to find a MAX. position where the OPE. indicator LED turns OFF. 3) Place a target at the detection position, and further turn the SENSITIVITY adjuster counterclockwise to find the position where the OPE. indicator LED goes out. 4) Fasten the SENSITIVITY adjuster at the middle point between the positions selected in steps 2) and 3). 5) Fasten the photoelectric sensor so securely as not to be displaced by vibration or shock. Notes: 1. Since the detectable distance depends on the material, color, size, shape and direction of targets, and the environmental conditions, check and adjust it using an actual target. 2. If the STAB. indicator LED does not come ON in step 4), reposition the detection face and repeat the procedure of steps 1) to 4) or pay attention to other factors such as ambient temperature variations, position of target, etc. 3. Please be careful not to apply excessive torque to the SENSITIVITY adjuster and the LIGHT-ON/DARK-ON selector switch. Light axis adjustment for Retroreflective type 1) Temporarily mount the reflector and the photoelectric sensor in proper alignment. 2) Move the photoelectric sensor left and right, up and down to find a position in the center of the range in which the OPE. indicator LED is ON. 3) Check the photoelectric sensor's operation when a target passes the carrying path. 4) If it does not operate, adjust the sensitivity. 5) Affix the reflector and photoelectric sensor in position firmly so that vibration or shock must not cause the light beam axis to shift out of alignment. Notes: 1. If the STAB. indicator LED does not come ON in step 3), reposition the reflector and repeat steps 1) to 3) or pay attention to other factors such as ambient temperature variations, position of target, etc. 2. Please be careful not to apply excessive torque to the SENSITIVITY adjuster and the LIGHT-ON/DARK-ON selector switch. Light axis adjustment for Thru-beam type 1) Swing the projector and receiver to left and right, and up and down to find a position around the middle of the OPE. indicator LED's ON range, and then secure them. At this time, confirm that the STAB. indicator LED is lit. 2) Sensitivity adjusting makes detection possible of translucent targets. For translucent targets, the SENSITIVITY adjuster is turned to the position where the target can be detected. Note: 1. If the STAB. indicator LED goes out during operation, the sensor detection does not work any longer. Check the situation and adjust the sensitivity again. 2. Please be careful not to apply excessive torque to the SENSITIVITY adjuster and the LIGHT-ON/DARK-ON selector switch. CAUTIONS These products are not safety sensors and are not designed or intended to be used to protect life and prevent bodily injury or property damage. 1. Operating Environment 1) The sensor should be used in an ambient temperature range of -25 to +60C -13 to +140F (DC type) or -25 to +55C -13 to +131F (AC/DC type) 2) Use an operating voltage in the range of 9.6V to 30V DC for the DC types and 21.6V to 264V AC or 10.8V to 264V DC for the AC/DC types. 3) The light intensity on the receiver surface should be less than 3,000 lux for an incandescent light source and 8) The sensor is immersion protected type, but this does not mean that it can be used in water or where there is direct impingement or rain for detecting targets. 2. Wiring 1) Check all wiring before applying power since incorrect wiring may damage the internal circuit. 2) Ground the frame ground (FG) terminal and ground (G) terminal when using a commercially available switching regulator. If a ground is not connected, switching noise from the power supply may result in faulty operation. 3) Wire 0.3 mm2 .0005 inch2 AWG22 or larger should be used for wiring up to a length of 100 m 328 ft. 4) Please use a fitting cable for wiring the connector type sensor to maintain the characteristic of protection structure. 5) Tighten the connector with a maximum torque of 0.8 N*m {8.2 kgf*m, 7.09 lbf*in}. 3. Detector less than 10,000 lux for sunlight. 4) Use a surge absorber as the internal circuit may be damaged if external surge voltages exceed 500V (for DC type)/4,000V (for AC/DC type) [(1.2T50)s single polarity full-wave voltage]. 5) Avoid use in locations with high concentrations of steam, dust , corrosive gases, etc. 6) Use a load relay with a rated operating voltage of 12V DC or 24V DC for the DC types. The voltage applied to the load relay is the operating voltage of the photoelectric sensor minus the internal voltage drop (maximum 1.2V NPN side, 2V PNP side). Voltage fluctuations should be taken into account. 7) The output circuit of the DC type contains a short-circuit protection circuit. However, be sure the inrush current does not exceed the maximum output current capacity for proper detection. 1) Keep the detector surface clean as excessive dust or dirt on the detector surface will decrease the margin of the sensing distance. 2) The front surface of the lens and case are made of polycarbonate resin (but the front surface of Retroreflective type is made of polymethylmethacrylate). Although it withstands water, weak acids and alkalines, aliphatic hydrocarbons, and oils and fats, it is not resistant to ketones, esters, halogenated hydrocarbons and aromatic hydrocarbons. 5. Other cautions 1) When using the optional mounting bracket, tighten the mounting screws with a maximum torque of 0.8N*m {8.2 kgf*cm, 7.09 lbf*in}. If the optional mounting bracket is not used, mount the sensor on a flat surface. 2) For the use UL and CSA approval KA1 photoelectric sensor, the connector and cable shall also bear the UL and CSA approval to use with. 3) The connector on the sensor's body side has a rotary structure. Be sure to rotate the connector according to the arrow mark on the sensor. The direction of connector must be determined before the sensor is mounted. *Rotating the connector in the reversed direction will damage the rotary structure. 4) Rotate the connector with a maximum torque of 0.2 N*m{2 kgf*m, 1.77 lbf*in}. 5) Handling for polarization filter and slit. 4. Moving Direction of the Target (for Trigonometric area reflective type) Take care with the mounting direction of the photoelectric sensor with respect to the moving direction of the target. 1 Pull click A into groove A. 2 Press the filter or slit on sensor to put click B into groove B. 1 Insert minus driver to groove B. 2 Move the minus driver to remove the click B from groove B. 101
