Dosing pump questions

First question: How does a 3 three channel dosing pump get connected to an existing Profilux controller. I'm currently using all outlets on both power bars and S1 thru S4 = Digital power bar. Does the dosing pump have an AC plug that just plugs into the wall? What do you connect from the controller to the dosing pump? I don't own one yet, but I want to make sure I have enough room. I tried to make out the instructions and none of it makes sense. "Plug the jack of the AC/DC adapter into the connector of the fan power supply (polarity: Inside +, outside -) and connect the
adapter to the mains. The control line has to be plugged with one end into one of the two western sockets; the other end has to
be plugged into a ProfiLux-output for switchable socket outlets (e.g. S1-S4 or S5-S8)??"

Second: has anyone used this dosing pump for continuous water changes? "Pump a little down the drain and pump a little back in the tank" at timed intervals. This is the main reason I want to purchase along with it's Profilux compatability. Any help would be appreciated.
 
Plug the doser into a power source and the control line plugs into the back of the doser and S1-S4 or S5-S8 plug on you Profilux unit. The control cord is the same type(western) used to control digital power bars. Super simple, I am looking at one right now.

The doser is supplied with power supply cord and the control cord so you are ready to go.

Ok...That makes sense. The screenshot below shows how I have my profilux configured. Please note that I have started my numbering sequence at S5. My S1-S4, S5-S8 cables are being used for the 2 powerbars. Am I understanding correctly if I say that the dosing pump will connect to one of the power bars as if daisy chaining? And will that free up S16 thru S19 (default PB settings) to be seperately controlled. Remember I said that all my outlets and S1-S8 are being used. Thanks again.

p.s. Do you see any issues using this dosing pump as a continuous water change device? I am figuring on replacing about a gallon a day.

Plug the doser into the last digital power bar daisy chain western socket and then number from the last digital socket

S5-S8 being used for power bars? Why are these analogue bars?

Digital bars go into S1-S4 only and daisy chain from there
 
I'm thinking of buying a doser, too, with either 3 or 4 dosing pumps. Will a multiple pump unit only require one link ("western socket" into the back of the Profilux, or does each pump require it's own socket?

Thanks. Erik
 
Thanks, Michael. I'll be ordering one shortly (along with the SMS module and the new chillers!).

Micheal, when are there specs on the chiller? How many do you need in a bank to chill 140 gallons? They look very effecient / low energy compared with compressor-based chilling units.
 
Do you really want my response to this?!

Best you check out the chiller thread and look at the wording Very carefully, cant miss it really it is in bold!

It was a reassignment trick to get individual control of each power bar socket. Numbering them from S1 created an overlap on both the power bars where 5 and 6 on the 6 outlet bar had the exact same function as 1 and 2 on the 4 outlet bar. I believe selecting S1 to S4 check box allowed this configuration to start at S5. I did this back in June of 2007 so I'm a little hard pressed to remember exactly WHY this works. But it was Matthias who told me to set it up this way to have 10 seperate outlets each individually controlled. The other way, all ten outlets work but with 2 duplicates there were essentially only 8 controllable outlets. It's hard to explain but it solved my problem.

So naturally, this reconfiguration brings the question to mind, "How would I hook up a dosing pump?". I'm thinking that the pumps will just continue where my 4 outlet bar leaves off. I just really wish I knew for sure before I buy one.
 
the doser just carries on when daisy chained from the last numbered digital socket, so if you last socket is 15 then the first pump will be 16 providing chained into the last power bar
 
And I guess I was wondering if these pumps are robust enough to handle continuous water change. I'm thinking of exchanging 1-2 gallons/day at perhaps 1 hour intervals.
 
I have mine set up to change out 3 gallons a day and it works fabulously. Just check the flow rate on yours like the instructions say and you can dial it in perfectly.

That's good to hear. Do you change yours all at once or at intervals? With normal evaporation does it affect your topoff at all?
 
I have mine set to change out 3 gallons/day over the course of 20 intervals. It puts in a little bit and then takes out a little bit and the evaporation is handled by the top off pump which is triggered by the float valve.

Thanks....what I'm trying to hash out in my head is how to prevent my auto topoff (which looks at sump level) and cont. water change (which should change sump level) from kicking on at the same time. Seems to me that this could start to knock my salinity all out of whack. I do monitor salinity with a conductivity probe. I'm just trying to come up with the ideal set up so I won't be replacing evaporated water with saltwater as well.

How do you differentiate between the two? Am I reading too much into this?
 
Mine has been up and running a few months now and my salinity has not changed.

I was worried at first that my levels would be all over the place but they are not. During the course of a day it *might* fluctuate slightly, but I only check the salinity once a week.

If you have an EX or a Plus II with salinity probe you could use the Profilux to make certain nothing ever changed, but like I said, mine has not changed and I test once a week.

You know I was thinking, if it becomes an issue I could use the level switch for auto topoff. I'll have a 4 pump unit and I could use one pump for topoff. The new software/firmware will allow for keeping the topoff from coming on when the water exchange is happenening. Now if I could just figure out how to put this level switch contraption together. :confused:
