Programming Question for Dosing Pumps

[customdusty]

I've been trying to get my program for dosing my 2 part working and I'm continually having problems. It doesn't help that I lost my manual for the Apex, so I've been doing trial and error.

Basically, I want to turn on my peristaltic pumps for 15 minutes at different times of the day, like every 4 hours.

For example, when I programmed in advanced as:

Fallback Off
Time 0:00 to 0:15 ON
Time 4:00 to 4:15 ON
Time 8:00 to 8:15 ON

and so on....

The program didn't work. As soon as I saved the program for the one of the pumps, the pump turned on instantly and it wasn't within any of the set times.

I don't know what else was going on, I monitored it for a day and the pumps turned on and off whenever they wanted. They were on longer than 15 minutes, they didn't turn on and off at the times, etc.

Please help me with how I should write the program.

Ok, think I got it now.

Manuals are online at the Neptune dowload section under support.

If you this on for 15 off for 4 hours you can use:

OSC 000:00/015:00/240:00 Then ON

OSC 000:00/015:00/240:00 Then ON


How would do it for pump #2 if it is to be run at the same intervals, but 1 hour after pump 1?

Use the following for the Outlet for pump #2:

OSC 060:00/015:00/240:00 then ON

What would the programs be if I only wanted to run the dosers 15 min. ? My dosing only requires about 15 min. a day.

Thanks

Then a simple time statement, for instance if you wanted to dose for 15 minutes at midnight:


Fallback OFF
Set OFF
If Time 00:00 to 00:15 Then ON

Thank you for the reply. I hope to figure all of this out myself one day. I fear if I don't learn the codes, I will never realize the full potential of the Apex.

Things seem as if they have been working, and my programs currently are set so each pump runs for 16 minutes every 4 hours, but are separated by two hours.

The curren programs looks like this:
Pump 1
OSC 000:00/016:00/240:00 then ON
Pump 2
OSC 120:00/016:00/240:00 then ON

What I would like to do is maintain the current total amount of dosing, but make the doses a bit more frequently and only during the times when my pH seems to drop during the night.

I want to run programs like OSC 000:00/008:00/120:00, but only between 10pm and 1pm for example. How do I program it so that the oscillating program only runs between the specified times, and then is off the rest of the time?

Just add overriding statements after the OSC command, for instance this is what I use:

ATO:

Fallback OFF
OSC 000:00/005:00/035:00 Then ON
If pH > 08.20 Then OFF
If Outlet PC_Lights = ON Then OFF

Instead of the Outlet statement, use:

If Time 22:00 to 13:00 then OFF

I am using the pH check temporarily, just to make sure it does not rise too much.

Thanks, I set it up this way now also.
