View Full Version : BRS pumps/apex problems- need help!

02/13/2012, 07:53 PM
Hello all I cannot get my 4 bulk reef supply (alk cal mg and top off) pumps to turn on when they are in 'pump' mode / I have them in spots 1-4 on the 8 bar - for example I have cal set up as 0/4:00/356:00 - and it won't turn on - when I go to manual I can turn it 'on' and it could over but if it is in auto it's a no go- idl what I am doing wrong- I can get it to control a candle light threwplig in spot 7 but cannot get it to work -
I have been running them as 'lights' but I would like to break up the time to better spread dosing and top off

Change the Control Type to Advanced, then copy and paste the program statements shown into a post here.

Fallback off
Osc 000:01/005:25/174.25 then on if feedA 000 then off

174:25 - not the dot above

The timing of the OSC command does not restart at ON when you change it to Auto. You have it programmed to come ON for 5 minutes out of every three hours (roughly). It is likely that it is still in the OFF portion of the cycle.

The OSC command is synced from midnight, offset by the first parameter. It cycles OFF > ON> OFF > and back to the first OFF and repeat. So in your code it, would be ON at the following times (ignoring seconds):

00:00 - 00:05
03:00 - 03:05
06:00 - 06:05

Also, be aware that the BRS dosers are low power devices and it is very likely you will have issues when operating them on the Triac outlets (1-3, 5-7). They tend to turn ON fine, but not OFF. It is best to run them on the mechanical relay outlets 4 & 8.

Okay well I changed my 'main' time to right before midnight then watch the code I have above do nothing! So then I changed it to 5 min a head and tryed it on auto and on - auto doesn't work and on just keeps on going way more than 5 min
And like isaid above I can get it to do my sump light with the above code but not my dosers

So it has to be the the bulk pump

So what outlets are you running them on and are you saying they're turning on but not off? There's a very real issue with running dosers on anything other than relay outlets - they just won't turn off.

I got On to work- its on auto 0/5/355 in spot 3 - turned on right when I turned it from off to auto and stayed on for 5 min now I am just going to check alk Tom and see if I have went up or down - I think the problem has been that I have turned it on the to auto and it waits to turn the pump on (?) bc I just switched this pump from light 'off' to pump then program then auto and it worked -
I have had them on as lights and never had any problems - I am basically only worried about my OT bc I have a Elos rimless and it evpos water like crazy

Now after playing more - just witnessed the pump NOt turning off - lol this is turning into a night mare

Stop. Reread both previous posts from Alan and me. If you are trying to run this dosing pump on any outlet other than 4 or 8 you will not get reliable performance. You stand a very good chance of overdosing or flooding your tank.

Not a nightmare, rather a well known issue - perhaps the most well documented issue surrounding the controller. Put your dosing pumps on relay outlets. Problem solved.

Thanks guys - I am dose alk calc mg and OT - soooo don't really know how to fix all this - the mg not to worried about but not sure how I should run 3 with 2 spots- is there a doser that doesnt have this problems? I could always use a power strip and 'timer' but kind of a kicks some of why I love the apex-

Options are:
- Buy another EB8
- Buy an EB4. All outlets are relay-controlled so you could put all 4 pumps on an EB4.
- put two pumps on outlets 4 and 8. for each of the two additional pumps, put it on a short extension cord having multiple taps. Along with each pump, plug in a small nightlight (incandescent, not LED). This will increase the power load and power factor enough to operate a TRIAC-switched outlet reliably.

Try an EB4 from Neptune. They are all relayed outlets.

It is what I am using to control my 4 BRS Dosers and has worked well.
