Connecting 7090 to 7097 controller

[rvitko]

Generally the 7097 should work flawlessly with the 7090, while for 7096 and 7095 a calibration of the 7090 can be needed. Try increasing 30%-40% if they don't stop anymore, I assume it is a calibration that is needed for the 7090 and I can walk you through that. The signal voltage changed when we added the 7090, it used to be 0-8V and is now 0-6.5V so all the speeds fall into a much tighter signal range. My guess would be that the signal for 30% is below the minimum and we just need to bump it up. If it works at 40% we will have our answer.

Going to 40% seemed to do it. The pumps are running again.

I attach the calibration procedure, pump model does not matter:


1. Connect the 6055 to your 7095 controller
2. Please turn your 7095, to the minimum power of 30% on both speed settings for the channel it is connected to.
3. Turn the 6055 to the external mode (yellow LED lit).
4. Turn the "pulse power" dial on the 7090 to the middle position
5. Hold the Foodtimer button on the 7090, watch the dial on "pulse power" until you see a short flash of the blue LED continue to hold the button.
6. Turn "pulse power" until the 6055 starts in the minimal range, it may need to be turned in either direction, turn slowly until it starts then let go of the food timer button.

If this does not work, what has worked best for me is to then find the minimum speed on the 7095 that the 6055 will run on, set the speed a little below that, so if it runs at 60% try 50% and repeat the calibration so it runs at 50%, then repeat slowly stepping it down in increments of about 10% until the pump starts at 30%. I have had it take as many as 7 tries but usually it works in 1.

Thanks Roger! Everything seems to be running fine now.

Great news!
