Suggestions for testing the variable speed port on a Tunze 6105

[AGreyCrane]

Anyone have any suggestions for testing the variable speed port on my Tunze 6105? I have connected two of them to my Apex via the Neptune cable but the pumps just keep on running along like they are not connected.

I'd like to test them out some how to validate that it is not the pumps them selves or the cable.

Thanks!

If you disconnect the controller cable and the pump runs and you can vary the speed with the potentiometer on the junction box, the issue is solely in the cable or controller. Be sure to return the pot to full power when connecting a controller.

Yeah, it works fine disconnected. The issue is when hooking up the cable, the Apex does not seem to be able to control it. The little lights light up on the VDM ports on the Apex but there is no change on the 6105.

Hoping to find some way of testing the 6105 without the Apex to make sure the connection on the 6105 is working properly.

Thanks,

If the pot on the pump works, the connection works, they share the same circuit.

Perhaps I can offer a suggestion. The cable Apex sells sometimes the end that plugs into the tunze connector the rubber is a little bit long either slide it back or cut the rubber about a 1/4" plug it back in and give that a try.

Oh I just knew this was going to work. I had noticed when inserting them the first time that they did not seem to seat all the way, though that some how slipped my memory.


... but, Alas, it did not work. I trimmed it back, it is definitely seated all the way in now, and no bueno. Still not spinning down the 6105s.

Thank you very much for the suggestion though.

Can you post your program for the variable speed ports and profiles in use?

I currently have this set for all 4 variable speed ports, so in theory ( as I understand it), it should turn off my Tunzes when they are plugged in right now:

Set PF5

Under profiles PF5 is set to:
Synchronize Disabled
Divide by 10 Disabled
Initial off time (Seconds) 0
On time (Seconds) 1
Off time (Seconds) 1
Minimum intensity 0
Maximum intensity 0

If the minimum intensity is set to 0 and the maximum intensity is set to 0 the pump will not spin. What you did basically was to tell the pump to start a 0% and finish at 0% Try this

Initial off time (Seconds) 0
On time (Seconds) 10
Off time (Seconds) 10
Minimum intensity 0
Maximum intensity 70

If that works then you can adjust the parameters.

That was actually the intent, I was trying to make sure the signal was going through, and the best way for me to do that was to turn the pumps off with the Apex over VDM. Nothing changes when I plug them in, they still run. Not turn off.

I picked up a multi-meter today and tested the output from the VDM and found that the VDM ports are putting out 10V whether on or off. Including being directly switched off (as in Auto, On, Off). So, it looks like I have a problem with my VDM ports.

Can you manually turn the output On and Off? You can set the output to Auto/On/Off. It would be good to know the basics to help see what the problem is. Btw Minimum intensity should never be less than 30%, else you can damage the pumps.
