Programming for ATK sensors and DOS as ATO

[Nep16]

I need to program my Apex for using my ATK optical sensor module with my DOS for use as an ATO. Can anyone please help with this?


I had been using a different peristaltic pump for my ATO but that pump failed yesterday and I have one open DOS head so I would like to use it for ATO. My previous programming for the dead peristaltic pump is below (it was a very slow pump so that's the reason for the very long on time of 999:00):

Fallback OFF
Set OFF
If Swx15_1 OPEN Then ON
If Swx15_2 CLOSED Then OFF
When On > 999:00 Then OFF
Defer 000:10 Then ON
Defer 000:10 Then OFF
Min Time 001:00 Then OFF



Swx15_1 is my low optical sensor.
Swx15_2 is my high optical sensor.
The DOS head that I want to use for ATO is DOS_11_1


Thank you very much for any help!

First set the dos wizard to add about 1.5 times what you think is typical daily evaporation over 24 hours. Then in the advanced tab add this.


If Swx15_1 CLOSED Then OFF
If Swx15_2 CLOSED Then OFF
When On > 999:59 Then OFF


You might be an engineer if...You have no life and can prove it mathematically.
