Apex Programming Help

Fallback OFF
Set OFF
If Time 22:00 to 06:00 Then ON
If Time 06:01 to 21:59 Then OFF
OSC 001:00/003:00/005:00 Then ON
If pH > 8.50 Then OFF


That is what I have it programmed to, but I am not sure its behaving like I want.
The goal is: Run the Alk at night, between the hours of 10pm and 6am. Osculating being on for 3 min and off for 5.
Dosing a total for 66ml through out the whole evening.
8 hours = 480 min. Doser is on 8 min schedule, running 3 of the 8 min.
Doser is 1.1ml per min. So running total 60 min through out the whole night and putting in 66ml.

Thanks

Is it best to break up the time? 22:00-23:59 and then a new command for 00:01-06:00?

Fallback OFF
Set OFF
If Time 22:00 to 06:00 Then ON
If Time 06:01 to 21:59 Then OFF
OSC 001:00/003:00/005:00 Then ON
If pH > 8.50 Then OFF

This line could be removed, as the default set setting is OFF, there is no reason to tell it to be off twice

Does the Line order make a difference? Does the apex read from the bottom up?

 

[Waterjockey]

Line order does make a difference.
No need to split the times up, it should recognize rolling past midnight

Try this:
Fallback OFF
Set OFF
OSC 001:00/003:00/005:00 Then ON
If Time 06:01 to 21:59 Then OFF
If pH > 8.50 Then OFF

It's too late for me to do math, but it looks like you are running more than a total of 60 min during the 8 hrs. Is the dosing pump on for 1 min every 8 minutes or on 3 min for every minutes?

@Waterjockey
Remove the Set OFF as this is handled by the OSC programming line

Fallback OFF
OSC 000:00/003:00/005:00 Then ON
If Time 06:00 to 21:59 Then OFF
If pH > 8.50 Then OFF

BUT the above coding does not match what you are wanting if you are looking to dose 66 ml a day, below is a a calculator and the result / Programming for dosing 66 ml a day

Use this calculator to program your dosser that hopefully is on outlet#4 or #8!!!!

Results

 

[Waterjockey]

Good catch! I didn't bother doing the math for the amount he was dosing, I was just looking at the programming sequence

I had never seen that calculator before, that is pretty cool, thanks.

 

[flounder]

agreed. I like the calculator.
Thanks for all the help, esp the math tips :)
