How do the indicators on Photoelectric Sensors operate?
There is a stability indicator (green) and an incident light indicator (red). There are four operation patterns depending on the amount of incident light.
Incident Light Indicator
The incident light indicator shows the amount of light entering the receiver.
|1||1.2 min.||Stable, light|
|2||1.0 to 1.2||Unstable, light|
|3||0.8 to 0.99||Unstable, dark|
|4||0.8 max.||Stable, dark|
Note:The operating level is 1.
