表 I 中罗列了传感器无法执行某项功能时应采取的各项措施。
LED 指示灯 / 故障界面 /
LED indicator/fault pattern
绿色 LED 未亮起或闪烁 /
Green LED does not light up or
flickers
绿色 LED 未亮起 /
Green LED does not light up
绿色 LED 未亮起 /

绿色 LED 未亮起 /
Green LED does not light up
黄色 LED 亮起，光路中无物体 /
Yellow LED lights up, no object in
the path of the beam
原因 /
Cause
尽管传感器准备就绪，但运行条
件不佳（信号冗余因数处于 0.9
至 1.1 之间 ） /
Sensor is still ready for operation,
but the operating conditions are
not ideal (operating reserve factor
between 0.9 and 1.1)
无电压或电压低于极限值 /
No voltage or voltage below the
limit values
电压中断 /
Voltage interruptions
传感器损坏 /
Sensor is faulty
传感器和背景之间的间距过小 /
/ Distance between the sensor
and the background is too short
措施 /
Measures
检查运行条件： 光束（光斑）完
全对准物体 / 清洁光学表面 / 重
新设置灵敏度（电位计） / 检查
开关距离，必要时调整；参见图
E /
Check the operating conditions:
Fully align the beam of light (light
spot) with the object. / Clean the
optical surfaces / Readjust the
sensitivity (potentiometer) /
Check sensing range and adjust if
necessary, see Graphic E
检查电源，检查整体电气连接
（导线和插头连接） /
Check the power supply, check all
electrical connections (cables and
plug connections)
确保电源稳定无中断 /
Ensure there is a stable power
supply without interruptions
如果电源正常，则更换传感器 /
If the power supply is OK, replace
the sensor
降低开关距离，参见图 F /
Reduce the sensing range, see
Graphic F
