wavebox

[billyzbear]

I'm not totally sure why it happened but my wavebox stopped working, no light on either. The powersupply was very hot. It was plugged into my apex and it showed I had a large amp spike. It's an older model with 6091 controller.
I don't have any extra parts for it so not sure where to start. Being the powersupply is very hot I would think it's the problem. I don't remember what you call the box with the gain on it but it wasn't hot. Please, help.

It is hard to say, but likely either the driver or motor has shorted and this is causing a power demand that excedes the power supplies capacity so it is getting very hot. A bad driver is the more likely cause but these are no longer available except as used and we do not have any more at the moment. You might try the used forums or eBay, otherwise you could upgrade to the 6215.200 pump by ordering kit 6260.015 on tunze.com, this is the new pump with the power supply and required mounting parts.

I have some nice meters and scope is there a way to test components? Like can I plug power supply in and test voltage coming out? Is there a way I can test driver? The driver is the box with gain? Motor is pump in tank?

The motor is the pump in the tank. You can check the power supply for output voltage the center pole is a common neutral and the outer poles are hot and will give the voltage speced on the power supply label, usually 19V and it will be AC. Beyond that, if the driver gets hot at the back where the heat sink is and a watt meter shows very high wattage, that is usually a dead driver. If the motor (pump) is dead, the driver will usually alarm and the wattage will be very low or near zero.

I left it unplugged since today. Tested power supply and it was and it is 22v. Plugged it into driver and it works now.
I tested eb8 and I'm getting 51v on some outlets and 9-10v on others, off. I would think 51v isn't going to work but would 10v be ok? It was plugged into the 51v outlet when this happened. Ideas on why?
I'll do some more testing.
Also, have tried to do a wave every other pulse with no luck. Basically make a wave have it go length of tank come back, go the length of tank again come back then make another. Do able? Could I also have it like this and every ten minutes or so go full blast? I only have the 6091 controller. Would I need a better controller like 7096?

On the board for some circuits it merges the two poles so up to 45V or so is to be expected. Most of the circuit board though is low voltage at 10V.

Typically intermittent failure is caused by a motor issue and won't be repairable. Typically this is caused by the motor locking up and overheating and this caused the Hall sensor to move from expansion so it is no longer lined up properly, after a few days they go out of sync and the pump stops and this will generally get progressively worse. Since all of the electronics are potted in the pump they cannot be repaired.
The wave is a function of resonance frequency and just one specific frequency makes a wave in each tank.

The whole thing was strange when it happened. I plugged an led fixture upto apex and when I went to turn it off the lights were flickering. So I turned it off at the switch, when I went to turn off t5 it started to flicker as well so left it on and when I went to turn off wavebox it turned off and would not start again and power supply got very hot.
Now, the wavebox is fine but it's now plugged into apex anymore.
