Hi all,
So my entire tank runs everything GHL. I bought this doser actually a while ago and have been tinkering with the software only and last flashed it to 1.19. I then put it away and went on my travels. Today I thought let me get this thing going. Take it out connect to it 1.0.8.4 which is what I had at the time I bought the doser started to read how to calibrate. Notice something..... my LAN would not connect for some reason.... LAN connection worked tested it on router just the doser wouldn't connect with LAN. Looked at the back no LAN activity (orange light yes no green).
I remembered reading somewhere new firmware required.
Anyway I went ahead and calibrated pumps 3 and 4 as a test and worked well whilst downloading control center 1.8.6 I think is the current version.
I go ahead install 1.8.6 and it says new firmware, perfect apply new firmware and success I am now on 1.20.
I go ahead and test my two pumps again 3&4 as I couldn't remember if I needed to re calibrate - The pumps are noticeably slower.... in sound and visibly - no fear I think needs a good old calibration. Let me test pump 2 first - SOUNDS and you can see VISIBLY it is moving better.
Now method to calibrate:
I have a container 400ml with 200ml of water and an equal container empty on the other side. I then have a 60ml syringe that I use to test under 50ml (containers only go to 50ml). So for calibration at Firmware 1.19 - Pump 3&4 calibrated to 43ml. After firmware pump 3 &4 calibrated to 9 ml.........
I calibrate pump 2 (the seemingly working pump) and it gives me 34ml as calibration. All is good I enter this into the values.
Then my test (which I did on pump 3&4 at firmware 1.19 and it worked nicely) -
I do a manual dose of 100ml - I use 100ml first as I can see in the container with 200ml if there is 100ml left and I can see in the empty container if there is 100ml (double checking) - (remember pump 3&4 on firmware 1.19 worked). And surprise surprise pump 2 on firmware 1.20 ..... gives me 80ml when I asked it to give me 100ml.
I think wait let me reset everything:
Firmware : 1.20
Calibrate: -- Speed: All set to 1
Pump 4: Calibration 9ml (looks odd) enter value
Pump 3: Calibration 9ml (looks odd again) enter value
Pump 2: Calibration 35ml this time enter value
TEST After calibration - should work right?
Pump 4: Please dose 100ml - Doses 6ml - Right....
Pump 3: Please dose 100ml - Doses 5.3ml - Ok....
Pump 2: Please dose 100ml - Doses 82ml - The pump that wishes it could.
I am highly confused at what is going on right now for this premium product that is suppose to be so sophisticated with 24v pumps that can dose to 0.5ml..... Let me just reiterate a few things for clarity:
1. This is a BRAND NEW doser. Besides me playing with software a month or two ago the pumps have never moved.
2. Yes the lines are Primed as best as possible (I have the old doser to so been here before)
3. It was working beautifully on 1.19 I just needed LAN to work hence the firmware upgrade.....
4. There is a BIG noticeable (I can upload video or sound file) difference in the speed, sound visible running of pumps 3&4 and 1&2 (1 is still a virgin not calibrated or touched - to scared...)
Thank you
