Running a dosing pump for 30 seconds in apex?

[Bob Ander]

Is it possible to run a dosing pump off of the apex energy bar for 30 seconds once every day? I have found ways to run it for 30 seconds multiple times but not just once a day.

Would 15 seconds twice a day be ok? OSC 000:00/000:15/719:45

Also 1 minute is pretty easy. If time 18:00 to 18:01 then ON, would turn it on for 1 minute at 6 pm

15 seconds twice a day works fine. I am dosing Carbon and accidentally brought my nutrients down to 0 so I need to cut back on dosing by about half. Weird because I’m still getting lots of algae on glass but I’m pretty sure my new Red Sea nitrate pro and phosphate Hannah checker aren’t lying to me.

Yes it’s possible. When do you want it to go off? Use an OSC statement for 30 seconds every hour, and then use an if time statement to keep if off for all the hours you don’t want it.

Good one @LobsterOfJustice! I didn't think about adding a second time command. I was thinking too small....trying to do it with one command.

could you write this out for me. I am unfarmilliar with the OSC command

Yes, that is exactly what I do:

OSC 000:00/000.30/719.30 Then ON
If Time 12:00 to 24:00 Then OFF

Pump will run for 30 seconds at midnight every day.

Is there anyway to do this for 45 seconds? I notice how you say if time 12:00 to 24:00 then off but doesn’t this leave 12 hours for the pump to be on?

The way the OSC command works is that the first set of numbers is the period, beginning at midnight that the outlet stays off; the second set of numbers is the period that the outlet is on; and then the third set of numbers is the period that the outlet is off. So, OFF/ON/OFF. If you wanted the outlet to be on for 45 seconds, beginning at midnight it would be OSC 000:00/000:45/719:15 Then ON. If you wanted the outlet to be on for 45 seconds at 12:30 AM, it would be OSC 030:00/000:45/689:15 Then ON. The time syntax then just shuts the outlet off for the 12 hours beginning at noon, overriding the OSC command. Clear as mud LOL.

Clear as much described that perfectly! That makes absolutely no sense to me but im just going to go with it. So the code I am putting in is

Fallback OFF
OSC 030:00/000:45/689:15 Then ON
If Time 12:00 to 24:00 Then OFF

and this will turn the pump on for 45 seconds one time per day at 12:30 pm?

 

[saltyhog]

Nope, that will turn it on at 12:30 AM

I think you would want OSC 750:00/000:45/719:45

Without the time command this oscillation would repeat every 12 hours. Best I can figure the longest oscillation you can program is about 16.65 hours.

Is that correct ca1ore?

 

[ca1ore]

If you don't mind the outlet coming on during the day, you can get OSC to work across the full 24 hours (the sum of the three time values should not exceed 1,440). So you could have OSC 440:00/000:45/999:15 Then ON which would run the pump for 45 seconds every day, but it would run 440 minutes after midnight ..... 7:20 am, something like that.

I've never tried a 24 OSC, but I don't see why it wouldn't work.

AM is what I meant. So the code I posed will work?

 

[lbacha]

Something else, no matter what times you put in osc it will restart at midnight every day. So even in your times don't equal 24 hrs it will start over.

Yes. Always confirm it of course just to make sure it runs as you want. Some of the energy bar outlets don't like small loads - my BRS dosers, for example, would sometimes get stuck on unless I put them on the relay outlets.

what are the relay outlets?

 

[ca1ore]

On the EB8, six of the outlets are triacs, two mechanical relays. The latter are better at switching small loads. They're marked on the unit; outlets 4 and 8 if I recall correctly.

Mine for Alk and Ca:

[Alk]
Fallback OFF
OSC 060:00/005:15/054:45 Then ON
If Time 11:10 to 19:59 Then OFF
If pH > 8.35 Then OFF
If FeedA 006 Then OFF
If FeedB 030 Then OFF
If FeedC 006 Then OFF
If Power Apex Off 000 Then OFF

[Ca]
Fallback OFF
OSC 000:00/005:15/114:45 Then ON
If Time 10:10 to 19:59 Then OFF
If FeedA 006 Then OFF
If FeedB 030 Then OFF
If FeedC 006 Then OFF
If Power Apex Off 000 Then OFF

This is not correct.
