Pacific Sun Kore 5th dosing Fan Club

[erik2302]

I know this has been asked here, but what voltage do the ATO/AWC pumps run on? I'm looking to replace mine (both the AWC and ATO have died)

I'd like to purchase something a little higher quality than what pacific sun provides (tunze ATO pump is what I have in mind.)

Thanks for the help.

I use these lab grade glass ones. I think they are $2/piece. My wife is a researcher so I have access to these as well as tubings

Ah man. That is perfect!

I/O Digital Port

Does any one have the wiring pinout diagram for the Kore 5th I/O Digital port?
I have a custom doser container (5" x 20" - 3 section). The Pacific Sun magnetic stirrer is too small so I'm building a stirrer to meet my needs. I could turn off/on with the Apex, but would rather have the Kore 5th doser control the stirrer to match dosing times.

I have the same issue. I switched over to Aquaforest 3-part and stuff settles out overtime. I am using 5.5L oxo containers and there is no way the stirrer would work. I found magnetic stirring plates online that would fit perfectly but don't have spare outlets on the cerebra.

The Kore's IO may even connect to the stirrer digitally. Only way to find out would be to use a voltmeter to see which pins go up when Kore 5th is supposed to be stirring each channel.

I seriously doubt PacSun will let us have the IO pinout.....

ATO pump needs to be 12v 500ah. I guess AWC pumps are the same but you can confirm that with PacSun service.

Yep .... going to Aquaforest on a large tank... dosing a lot of product each day and need bigger containers. If needed I'll pull out the voltmeter, in the mean time hoping someone else has gone down this road.

The pump cannot be more then 4 watts. I have a dead doser to prove that. 12v x 0.5a is too much.

What ever happened to the "soon to be released" android app Prem posted about nearly 2 months ago now?

 

[Przemek_PacSun]

From technical point of view - it's possible to connect other stirrers than our (or other pumps than our original DC pump) - however any modification will be done on Customer responsibility.
Maximum power output for DC pumps(AWC pump) is 5W.
Magnetic stirrer need digital relay(like SSR) for switching on/off external stirrer because on digital output port there is only digital signal (0/1) - you can't connect any power device(even taken very small power from doser)

Thanks Przemek... yes, I understand only a relay can be used for the stirrer. I'll have the Apex turn the DIY stirrer off/on throughout the day.

Does the mixer work with those bottles? I tried water bottle (since not flat bottom would not work). Tried little glass bottles for sparkling water with flat bottom and still no luck. Seems glass to thick. This is getting to be a pain....

Kore 5th Stirrer issues

Kore 5th Stirrer issues

Does anyone have the following issues with Kore 5th Stirrer:

1. All 5 channels of the stirrer on at the same time even though I set each channel at 5 min. a part.
2. My stirrer magnets spinning throughout the day even though I set to dose 4 drops one time only. Still haven't able to track down the sequence yet.

I am using MacBook Pro TouchBar with latest MacOS, Kore version 1.6b and firmware still stuck at 1.6e cause there is no Firmware update button on mac software.

Thanks!

Did anyone find a spec on a 5w pump that has a great head pressure than 4'? I would love to replace my ATO and AWC pumps. It's to the point where im considering selling the unit.

ALso, is there an update for the alk monitor on the anticipated release date?

You have to use relays to control anything other then original pumps. Trust me, I burned a doser trying to run 5w Spectrapure pumps. I got it working, pumping and pulling 40ft at 200ml/min. PacSun was nice enough to make firmware changes for me so I can change out 40 gallons per day. Goods news is you can use any kind of DC pumps you want, outputs give enough to switch heavy duty automotive relays.

Oh yea i remember when that happened, was back when i had issues with head pressure on the kore DC pumps not meeting expectations.
I'll see what i can dig up, may have to hit you up with some questions in the future.
thanks for the response!

Sure, I will be happy to help.

We plan to release special module with SSR relays which will allow to connect any external pumps.
Probably we will show it during Macna 2017.

ALK monitor! More details and release date please.

 

[Przemek_PacSun]

Part of kHLab was software for wireless firmware update working on mobile devices.
We finished it now and together with latest firmware and mobile app will be published probably today.
We didn't want to release kHLab without full support from mobile devices - now when windows app and android app are ready we will release fix for Mac OS app because some customers reported problems with connectivity - a specially on iMacs which have shared Bluetooth modules with mouse/keyboard.
New firmware / software include also improved calibration procedures which are very easy now.
More informations I promise publish very soon.

 

[Alfrareef]

Are you talking about a KH online monitor?

Hi Przemek,

Could you please explain how to calibrate my dosing pumps?

1. I just don't understand why you need to click Start calibrate while you also have Check Calibration? Should it be just Check Calibration for 10ml Test dose. Then based on the results just use the Flow Adjustment then Check Calibration again and adjust the Flow Adjustment until it's perfect?
2. Also why need to manually use Flow Adjustment? It should be simple as to record the results and the system should adjust it accordingly. Do that a few time then it would be perfect. For example, if I test 10ml and the results is only 9ml. Record that and the system should adjust its flow automatically.

Hello
Sure, we are here for help.
1. Start calibration - it start whole process and allow for calibrate dosing pump(each channel separately). Check calibration allow for checking calibrated channel on exact amount of liquid.
Why it's done like that?
Dosing tubings due their physical nature change hardness during pump work time. Tubing have different hardness in first second of work - and also different in 20s. Different hardness mean different "flow capacity". Longer pump is working - flow is changing.
for example:
If you will calibrate channel for dosing properly 10ml of water it will do that every time(lets agree that it take 10 seconds).
But, if you will want to dose 100ml (100 seconds) it will dose LESS liquid than 100ml - because tubing hardness/flexibility is different in first 10s than on others.
2. Precise flow adjustment allow for very precise calibration tuning without starting process again(start calibration > stop calibration etc). For example - if your pump after first calibration attempt dosed 10.5ml instead of 10ml - using precise flow adjustment you need increase real flow thru the pump.
Our Kore 5th dozer is only one dosing station on market which have minimum liquid resolution 0.01ml. Our competitors have minimum 0.1ml. Why it so important?
Usually single water drop have about 0.04ml. Depending from liquid density - it can change even to 0.06ml.
So having pump with minimum resolution 0.1ml you can't dose 1 drop. You will be able probably dose 2-3 drops - than next 5-6 but without being sure how many drops you have doses.
It's looking completely different on Kore 5th.
So if you calibrate channel on 10ml probe - but you want to dose only 2 drops daily you need to check channel on precise adjustment flow.
If your liquid density is higher - you can set on Check calibration 0.07ml and test channel. If it dose more than should - you can decrease it to 0.06ml

We are releasing in this weekend big software update - calibration process will be easier than actually.
