noise tunze motorcontrolers with Profilux

[Hawaiigold]

I have two 6100 powerheads. So far no problem.
Today I started controlling them ( I have a Profilux Plus II aquarium controller)
to make sinus waves.
Now, with every sinus waves the motor controllers hum in the same frequency. Is that normal? Can I do something about that?
The control voltage is 1 - 8V

Thanks for any help

Try setting the voltage to 3 - 8V. Also, set the minimum pump speed to 30%.

I experienced similar issues until adjusted these settings. Now it's all fine.

Yep, That sounds like the prob.

Me too...

I've got them set at 100/30 and 99/31

Thanks for the help . I did that. One controller is quite now. The other one still makes the same sounds just not as loud as before. That one is screwed directly to the aquarium stand. You think removing it from the wooden frame would eliminate the sound?

thanks

If you can utilize the Tunze magnets, then I'd try them. I use them, and have benefitted from being able to move them a hair or so to stop any vibration.

Oh, that makes sense. Because the quiet one is the one with the magnet. I'll try moving the over one around.

Thanks
