措施 /
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 be‐
low 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 connec‐
tions (cables and plug con‐
nections)
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 inter‐
ruptions
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
当 Health 存在且随后观察到
输出信号时当 Alarm 存在且
随后观察到输出信号时，黄色
LED 闪烁 /
Yellow LED flashes; if Health
is present then take note of
the corresponding output
signal; if Alarm is present
then take note of the corre‐
sponding output signal
尽管传感器准备就绪，但运
行条件不佳 / 此外在 Health-
输出端： 切断了电源 /
Sensor is still ready for ope‐
ration, but the operating
conditions are not ideal/
additionally with health out‐
put: power supply interrup‐
ted
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）（示教） / 检查
开关距离，必要时调整；参
见图 F. / Health 输出端：检
查电源，检查整体电气连接
（电缆和插头连接） /
Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
object. / Clean the optical
surfaces . / Readjust the
sensitivity (potentiometer)
(teach-in) / Check sensing
range and adjust if neces‐
sary; see graphic F. / With
health output: Check the
power supply, check all
electrical connections (ca‐
bles and plug connections).
黄色 LED 闪烁（非常短
暂） /
Yellow LED flashes (only
briefly)
示教模式 /
Teach-in mode
检查示教模式 /
Check the teach-in mode
黄色 LED 亮起，光路中无物
体 /
Yellow LED lights up, no ob‐
ject 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,
