Universal I/O 1 serves as an output for the small warning field and for the contami‐
nation error. The output is evaluated in the controller in such a way that it triggers
cleaning.
Recommended parameters for cleaning
Efficient cleaning
1
Stop condition after 4 cleaning steps
2
Air supply for connections A and B: 400 ms concurrently for each step
3
400 ms pause
4
Total duration of a cleaning step: 800 ms
Complementary information
You can adapt the example to your application, for example by using only one of the
two signals as a trigger or by changing the duration of the cleaning. The parameters
should be selected in such a way that the improvement in availability is in reasonable
proportion to the consumption of compressed air and energy.
If you use a timing relay or a time delay valve, you can implement two-stage cleaning
even without a controller.
The electrical data of the outputs can be found in the operating instructions of the
outdoorScan3 Core I/O.
