必须根据当地特定的法律法规废弃处理传感器。如果其中含有可回收材料（尤其是
贵金属），则必须在废弃处理时回收利用。
SICK 传感器无需保养。
我们建议，定期：
• 清洁镜头检测面
• 检查螺栓连接和插头连接
原因 /
Cause
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
尽管传感器准备就绪，但运
行条件不佳 /
Sensor is still ready for ope‐
ration, but the operating
conditions are not ideal
传感器和背景之间的间距过
小 /
/ Distance between the
sensor and the background
is too short
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 sen‐
sor and the object is too
long or sensing range is set
too short

表故障诊断
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 /
检查开关距离，必要时调
整；参见图 F. /
Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
object. / Clean the optical
surfaces . / Readjust the
sensitivity / Check sensing
range and adjust if neces‐
sary; see graphic F.
降低开关距离，参见图 F /
Reduce the sensing range,
see graphic F
增大开关距离，参见图 F /
Increase the sensing range,
