Measures
绿色 LED 未亮起 /
Green LED does not light up
无电压或电压低于极限值 /
No voltage or voltage
below the limit values
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)
绿色 LED 未亮起 /
Green LED does not light up
电压中断 /
Voltage interruptions
确保电源稳定无中断 /
Ensure there is a stable
power supply without
interruptions
绿色 LED 未亮起 /
Green LED does not light up
传感器损坏 /
Sensor is faulty
如果电源正常，则更换传感
器 /
If the power supply is OK,
replace the sensor
黄色 LED 亮起，光路中无物
体 /
Yellow LED lights up, no
object in the path of the
beam
传感器和背景之间的间距过
小 /
/ Distance between the
sensor and the background
is too short
降低开关距离，参见图 F /
Reduce the sensing range,
see graphic F
光路中有物体，黄色 LED 未
亮起 /
Object is in the path of the
beam, yellow LED does not
light up
传感器和物体之间的间距过
大或开关距离设置的过小 /
Distance between the
sensor and the object is too
long or sensing range is set
too short
增大开关距离，参见图 F /
Increase the sensing range,
