New 6105 pump, BAD clicking

[jdthomas24]

i just wanted to drop in on this one..Roger... Awhile back i had the popping/ clicking on 0-100 and i thought that 30 was the lowest we should go to prevent this form happening. Can we actually go down to 0 for ramping?

ya i just tested that and they go crazy with clicking.... of course we already know we have issues......

0 is fine and 30-100 are fine. What our controller does is if you set 0/ 100% for on and off for a fraction of a second it does 0-10% and then jumps to 100%, the only reason for this is to ease the magnet down and reduce clicking further, 0-10 happens over about .05 seconds on the 7092 and 7096.

Hi Roger, my left pump impeller does is fine but the right pump impeller does the 2mm smacking.

Why is only one of the coil is positioned higher?

Because a human does these steps and their is some variation. The plastic is made by a machine, the coil is made by a machine, a human completes the soldering of the coil to the cable and circuit board inside and positions it and then a robotic arm seals the finished unit with polyurethane. A small variation between units is possible.
