Is it harmful to have the 6201 cycle on/off

[Deleted member 143833]

I am considering setting the low-end below 30% but that causes the pump to cycle off (it appears anything below about 25% == off). Can the pump handle this (I notice that the manual for the controller suggests keeping the low-end above 30%.

30% is as slow as these pumps can go, below 30% they will knock and the rotation is not fast enough to keep the pumps going, it could cause damage to the motors.

Someone mentioned that the WaveBox does this (stops the motor during its cycle); is there something special with the pump used in the Wavebox????

 

[rvitko]

Yes, it turns off and on but it doesn't slow to below 30%. It is the sub 30% power on which could damage the motor.

Is 0% the same as off in the electronics of the motors? Since the WaveBox is also controller-based I suspect that it is not "really" removing power (e.g., the same as would happen if it was unplugged).

Put another way; is there a power level that can be used to temporarily stop the motor during a wave cycle?

I don't know for sure, I know though that giving the pump 10-25% power is a bad idea, if it is really giving it 0% it should be fine.

Since we are talking about a percentage (30%) I am reminded of the fact that the voltage is settable on my 6055's power supply. It would seem to me that 30% of one voltage is definitely different than 30% of another voltage. IS there a particular voltage that should be selected when connecting the pumps to the controller?

 

[rvitko]

No, a 6000 is just a 6100 with less voltage as well. It is not possible to give less than 12V to the driver in either case which is the lower limit.

I hope the folks at Tunze send the Folks at Neptune a Holiday Card this year cause of the apparent Halo effect I imagine their Aquasurf will cause with the Streams.

I for one purchased 2 6201's to use with mine.
