Dosing pump programming help

[aqualab]

I need some help here please.
Profilux Plus II - Digital Power Bar - Slave Doser (two pump)
S1-S4 connection. Pump runs in manual mode overide.

I have the dosing pump plugged into socket/outlet #1 on the digital power bar. Socket function S1 is set to timer. I cannot seperate run time on the two pumps - they run in parallel.

I want to dose Parts A&B but with a couple of minutes seperation between the two pump's operation/run time. I have tried several times to program accordingly - no luck. What am I doing wrong?
Should timer #1 switch mode be on Auto Dosing or Normal? If set on Auto Dosing - then I can't control the time of day I want to run dose, only dosing rate? How do you program pump #1 to start at 10:00am and run until 10:01? Pump #2 to start at 10:05am and run until 10:06am? If I set the switch modes to for both pumps to Normal instead, I can control start/stop time, just not doser rate right?

Thanks

Two thoughts...

You're using a switchable plug??? Mine is plugged into the wall - always on. This doser needs the power to make decisions. Now use the computer to change times and doses.

2nd - you should allow it to dose automatically. This way the doser breaks up your requirements throughout the day. The dose is more subtle to the system and won't cause any reactions.

ie - 100ml / day with 10 doses will give you 10ml / dose 10 times a day. (be sure to calibrate your pumps)

does that help???

Hey tnoblett,

The doser requires the Profilux controller to run it, this isn't a stand-alone doser. I have it plugged into the digital power bar - socket #1 which is set up to be always on/powered. If I set to autodose, I can only control flow/dose rate but not time of day - guess that doesn't matter. I like your suggestion of spreading the dose out throughout the day. My tank is an Elos 20-gal nano, so looking at approx 60ml each of part A&B. 12ml per run, 5 times a day, I will dial in better after checking parameters. Without being able to do an actual start time though, I'm finding it hard to verify flow rates and run times per episode. Does that make sense to you?

Thanks for your help and suggestion.

I understand it is the slave version, so's mine... You don't need to waste a plug on your digitalbar - a regular plug is fine.

The pumps need to be calibrated and then it will do the calculations for you. Hit the manual button and dose for 1 minute. This will tell you the flow rate of that pump (50 - 60ml / minute). My two pumps were slightly different (55, 60 and 50ml / min). Go back into the program and enter the rates (default is 60 I think). Now the computer will calculate how long to turn on each pump to dose 60ml (or 12ml 5 times a day).

This take us out of the equation... It does it for us...

Ahhh... ok, I understand the plug suggestion now, good point - thanks.

When you program auto dose - how do you seperate times for dosing in auto - I want the Part A and Part B to dose seperately. Does it also calc random dose time in auto config?

Thanks Again

random dosing... never thought about that one...

mine have never dosed together over the last 3 - 4 years. i have mine set for 10 doses per day (alk - 40 ca - 110ml), so if we calculate for how often and for how long the values will come out different for each dose (alk or ca) because the pumps are have different rates and the ml doses are different. right? therefore you don't have to worry about it dosing together. i guess if you want to force them to be different you can have one dose 5 / day (every 4.8hrs - 24hrs / 5) and the other 6 / day (every 4.0hrs - 24hrs / 6).

you shouldn't worry about the two mixing and reacting with each other - i have just never seen that happen in my system...

Ok, I have the doser plugged directly into a wall outlet - power is on to the doser. I set both 1 & 2 timers on autodose with 60ml flowrate, 12ml per dose, 5 times per day (I will run a flowrate test to verify actual flowrates after I get this setup to actually operate for me so I can make sure I have everything programmed correctly). My doser is set up as pump sequence 1-4 (only have a two pump doser). Does timer #1 control dosing pump #1 and timer #2 control dosing pump #2 respectively? Sorry for all the questions but I have messed with this so much over the past couple of days that I am beginning to forget what programming without success I have tried. Before this I was wrestling with pairing up the AI LED light - wasn't as difficult as this.

I'm wondering if my control cables are connected correctly. I am coming out of the S1-S4 port on back of Profilux controller to one of the doser's ports, from the other doser port to the digital power bar? I have checked the box on the timer page which states digital power bar connected on S1-S4. I believe the doser is a pass through to the digital power bar correct? So should I be setting up the two individual doser pumps in autodose on timer's #5 & #6 respectively? Or doesn't it matter? Just not understanding the whole S1-S4 and S5-S8 port thing and how it goes with the digital power bar's 6 outlets.

 

[tnoblett]

only if it is setup in your socket functions as such.

remember the computer sees your doser as another digital socket.

** sockets 1 - 6 for me are for the powerbar
** sockets 7 - 10 are the doser pumps or timer 7 - 10 so there are no conflicts (1-6 are taken already)

this was done under programing your powerbar / doser when you first started or should have been done.

**timer screen - (timer 7) program each timer to your dosing needs (5 times / day @ 12ml / dose) and (timer 8) to (?? times / day @ ??ml / dose). you can also change the pump flow per hr here when you run that check.

save and load you're done...

pm'ed

 

[tnoblett]

give me a call and i'll help with the set-up of the digital powerbar with the doser...

sounds like they are conflicting... numbers in your pm...

Thanks Tim - I appreciate your taking the time to help me get my programming straightened out. Working fine now.
