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)
确保电源稳定无中断 /
Ensure there is a stable
power supply without inter‐
ruptions
如果电源正常，则更换传感
器 /
If the power supply is OK,
replace the sensor
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

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).
检查示教模式 /
Check the teach-in mode
降低开关距离，参见图 F /
Reduce the sensing range,
