Light Curtain Muting
Light Curtain Muting Issues
If a load or pallet stops while transfering through a light curtain, it is most likely an issue with the muting of the light curtain (sometimes called a light screen). To better understand the muting sequence, refer to the article titled General Safety Information.
Almost every muting issue is caused by an improperly aligned, or improperly set muting photo eye. This photoeye can be mounted many different ways, but it will usually be the photoeye inside the fencing, closest to the light curtain. Bellow are common symptoms and remedies:
| Symptom | Cause | Action |
|---|---|---|
Load stops immediately when reaching the light curtain |
Load is reaching the light curtain before the muting PE senses the load |
Increase the sensitivity, relocate, or adjust the angle of the muting PE |
Load Stops sporadically in the middle of the light curtain |
The photoeye is flickering as the load transfers |
Increase the sensitivity or adjust the angle of the muting PE |
Load exists the fencing, but the robot is e-stopped |
The photoeye is too far from the light curtain |
Move the photoeye closer to the light curtain |
Check this photoeye's performance and alignment before investigating other issues that may be causing muting issues.
