Hi Shoggy,
Im having fun playing with the AE5 on the bench working out the best wiring and sensor setup and have found a small issue with RPM sensing on the Koolance D5 vario with RPM sensor.
I have 4 x D5's, 2 with RPM sense and they both dont report an RPM signal until I change the RPM sense calibration to 4 pulses, which means the AE5 then reports them at half speed (2400) when they are actually at 4800rpm?
When the AE5 is set to standard 2 pulses, when I first plug in the pump the RPMs are reported while the pump spins up, then at about 3000rpm RPMs AE5 report 0RPM until I adjust the pulse sense to 4 and it then shows the pump at half speed.
The PA2's report the correct RPM signal from the D5.
Is this a small bug or another dirty signal problem?
FYI for those wondering the AE5 runs a D5 all day no problem at full power, about 1300mA. I have the waterblock heatsink fitted without waterflow yet and the temp stays around 60c but climbs to 85c when running pump at minimum 7v. This means when I hook up water cooling to the block I should be able to run 2 D5s off it maybe more. I have a few PA2s but they overheat at 80c when the pumps are at running 7v so Ill probably be using AE5 to run the D5s.
Cheers
