Apex programming for kalk reactor

[OutColdCRNA]

Looking for some help with programming my apex to run my Kalk reactor. More specifically the magnet stirrer. I would like the stirrer to kick on for about 30 seconds every two hours.
I’m hanks for any help!

Would I need to write “if” statements for each time interval I would want? IE:

If 10:00 then on if 10:02 then off

here’s mine

Fallback ON
Set ON
OSC 001:00/009:00/170:00 Then OFF
If pH > 8.55 Then OFF
If Time 12:00 to 19:00 Then OFF

I want to say it stirs 9 minutes every three hours. the minute delay is to keep it from stirring when the doser runs.

Thanks for the code! So if I want it to stir more frequently I just add the times to the OSC line? How does the code tell it how long to stir for?

Let’s say you want stirrer on for 30 seconds at the start of every hour. You would use:

Fallback OFF
OSC 000:00/000:30/059:30 Then ON


Since your initial timer is 000:00, it will turn on at the top of every hour for 30 seconds, then off for 59:30, and repeat forever.

If you ever want it to run at a different time, such as 15 minutes past each hour, then move some of the minutes from the 3rd timer to the 1st timer. For example: OSC 015:00/000:30/044:30 Then ON.

So if I’m understanding right. If I want to come on every two hours for 2 minutes. With an offset of 5 minutes to compensate for dosing then the programming would look like this?

Fallback ON

Set ON

OSC 005:00/002:00/118:00 Then OFF

If pH > 8.55 Then OFF

I set this programming into my apex and when I set the switch to auto it stays on and the kalk reactor continues to spin after the 2 minutes. What am I missing?

If the OSC statement ends with "Then ON," the outlet will be Off during duration 1, On for duration 2, and off for duration 3
If the OSC statement ends with "Then OFF," the outlet will be ON during duration 1, OFF during duration 2 and ON duration 3

 

[OutColdCRNA]

If the OSC statement ends with "Then ON," the outlet will be Off during duration 1, On for duration 2, and off for duration 3
If the OSC statement ends with "Then OFF," the outlet will be ON during duration 1, OFF during duration 2 and ON duration 3

Thank you! it appears that the way I have written then code with the then on statement would indicate that I am off for 5 min. Then on for 2 then off for 118 min. But the stirrer stays on while the switch it is auto.

Ah correction. I had then off. Have changed to then on. Let’s see what happens.
