Frequently Asked Questions
Does the OS32C detect objects through glass or transparent surfaces?
No, mirrors and mirror-like objects must be avoided as they can hide parts of the monitored area.
What precautions should be taken when setting up multiple OS32C units?
To prevent interference, different scanning positions or physical shields may be required. Mutual interference should also be prevented when transferring data.
How is the safety distance calculated after changes to the system?
If the response time changes, a re-calculation of the safety distance is required to ensure safe operation.
What types of surfaces interfere with the OS32C's performance?
Contaminants like dirt, dust, and retro reflectors or strong interfering light sources can degrade performance and cause false operations.
