Control of spray jets
Task:
The customer has primer coating spray
jets that get clogged from time to time.
This clog can cause a reduction in
quantity of primer or an unequal
amount over certain areas being
applied. The customer has been trying
photoelectric sensors, but with limited
success. The customer needs a simple
pass or fail solution.
How to ... (Setup and configuration)
Set up the AS30 for Centre Determination in the Process setup using the device with a
Reflector in reflector mode.
The measurement value can also be monitored using the analogue output or IO-Link for
more variables. With IO-Link, you can have four pre-configured tolerances.
•
Run a reflector teach, followed by an
easy teach to evaluate the first
result
•
Run an advanced teach and based
on the reflectivity and transparency
of the spray, select your sensitivity.
In our case “Middle” was suitable
•
In the Configuration Qint, set your
tolerance values in window mode
and output to QL1
