113.延时操作——如果在关闭延时结束后，红色LED指示灯熄灭，则控制装置进行了正确的调整，并应使用锁紧螺钉锁定设置。如果红色LED未熄灭，则通过微调感应范围略微减小感应范围，并重复步骤12和13。14.单次操作-在单次射击时间结束后更换控制器前面的目标。如果红色LED亮起，则设置正确，可以用锁紧螺钉锁定。如果红色LED未亮起，则通过微调感应范围略微减小感应范围，并重复步骤12和14.15.使用开关选择“亮”或“暗”操作模式。16.使用开和关定时电位计调整所需的延迟。17.调整感应范围后，拧紧锁紧螺钉。感应距离可能会稍微增加。通常.25 12岁时（.63cm） （30.5厘米），.12 （30.5cm）在6 （15.2cm）和.062 （1.57cm）在3 （7.62cm），用于背景和目标。如有必要，可通过调整至11.75来补偿感应范围变化 （29.8cm）对于12 （30.5cm）抑制点，5.875 （14.9cm）对于6 （15.2cm）抑制点和2.95 （7.46cm）对于3 （7.62cm）抑制点。拧紧锁紧螺钉后，重复步骤5和6以验证范围。应用注意事项为了获得背景抑制控制所需的高灵敏度和清晰截止，使用了两个光电探测器。一个探测器探测到近距离的物体，另一个探测器将探测到更远的物体。如果进一步的输出信号（背景）大于或等于接近信号，控制保持关闭，如果接近信号大于背景信号，控制输出将打开。两个光电探测器的相互依赖性和重叠的感测区域要求被感测对象在特定方向上通过传感器，否则可能发生错误操作。因此，对象始终应在与控件垂直的x轴上移动。参见下图。
3. Time Delay Operation -- If after the off delay has elapsed the Red LED indicator turns Off, the control has the correct adjustments and settings should be locked with the lock screw. If the Red LED does not turn Off, slightly reduce the sensing range with the fine sensing range adjustment and repeat steps 12 and 13. 14. One-Shot Operation -- Replace the target in front of the control after the one shot time has elapsed. If the Red LED turns On, the settings are correct and can be locked with the lock screw. If the Red LED does not turn On, slightly reduce the sensing range with the fine sensing range adjustment and repeat steps 12 and 14. 15. Select Light or Dark operate mode with switch. 16. Adjust for the desired delays with the On and Off timing pots. 17. Tighten the lockscrew after adjusting the sensing range. A slight increase in sensing distance may occur. Typically .25 (.63cm) at 12 (30.5cm), .12 (30.5cm) at a 6 (15.2cm) and .062 (1.57cm) at 3 (7.62cm), for both background and target. If necessary, sensing range variation can be compensated for by adjusting to 11.75 (29.8cm) for a 12 (30.5cm) suppression point, 5.875 (14.9cm) for a 6 (15.2cm) suppression point, and 2.95 (7.46cm) for a 3 (7.62cm) suppression point. Repeat steps 5 and 6 to verify the range after the lockscrew is tightened. APPLICATION PRECAUTIONS To obtain the high sensitivity and sharp cut-off required in a background suppression control, two photodetectors are used. One detector senses objects in close, the other detector will sense further out. If the further out signal (background) is greater than or equal to the close in signal, the control remains Off, if the close signal is greater than the background signal, the control output will turn On. This interdependence of the two photodetectors and overlapping sensing areas require that the object being sensed passes by the sensor in certain directions or false operation could occur. Therefore, an object always should travel on a x-axis perpendicular with the control. See figures below.
