Aim the receiver to get the maximum analog output (20 mA). Move the receiver up and down, left to right to determine the area that produces maximum output. Aim the receiver in the center of that area then securely mount the receiver to maintain the position. Adjust the gain using the Sensitivity Control to produce 20 mA or the desired maximum current output. Use an ammeter to measure the milliamp current output from the sensor. Mount the emitter or reflector, then loosely mount the To ensure proper adjustment for best sensitivity, be certain that the current has not become saturated above the 20 mA Mount the emitter or reflector, then loosely mount the receiver. Aim the receiver to get the maximum brightness on the Light Indicator. Adjust the Sensitivity Control (gain) to maximize the brightness. Then securely mount the receiver to maintain the position. maximum limit. This makes normal detection impossible because the deviation of output at saturation becomes too small for differentiation. The Easy Method: The simple way is to use the Operation Point control. Set the operating point at 20 mA (fully clockwise), then search for the position that turns on the Operation Indicator. For Diffuse Reflective Sensors Using Indication: Using Analog Output: Securely mount the diffuse reflective or mark detecting sensor, or diffuse reflective fiber-optic sensing head. Place the object to be detected at the position where detection should occur. Adjust the Sensitivity Control (gain) to the point where the Operation Indicator lights. Then fine-tune the gain to maximize the brightness of the Light Indicator. Securely mount the diffuse reflective or mark detecting sensor, or diffuse reflective fiber-optic sensing head. Use an ammeter to measure the milliamp output from the sensor or E3XA amplifier. Place the object to be detected at the position where detection should occur. Adjust the gain using the Sensitivity Control to produce 20 mA or the desired maximum current output. To ensure proper adjustment for best sensitivity, be certain that the current has not become saturated above the 20 mA maximum limit. This makes normal detection impossible because the deviation of output at saturation becomes too small for differentiation. INFLUENCE OF FLUORESCENT LIGHTING Do not allow direct exposure of fluorescent light on the receiver (through-beam types) or emitter/receiver (reflective types). This may have adverse affects on the analog output current. CORRECT INCORRECT When mounting the sensor, keep the angle formed between the light of the fluorescent lamp and the optical axis of the sensor at more than 15 degrees. AMPLIFIER OUTPUTS Analog Output Logic (On/Off) Output Set the analog output by allowing a hysteresis of more than 2% full scale (about 0.3 mA), also taking into account the effects of external fluctuations. This effect is already taken into account when using S3A-D and S3A2 analog sensor controllers. The differential for the discrete On/Off logic output is set at about 2 mA. Output short-circuit protection is provided. 11 E3SA E3SA OMRON ELECTRONICS LLC OMRON ON-LINE OMRON CANADA, INC.
