Apex control

[Eud]

I purchased two 6095 powerheads, and I'm going to control them with an Apex VDM. I posted this question on the Neptune forum, but perhaps the Tunze one is better.

In the Apex comprehensive guide it says that the DIN-5 connector on the Nanostream 6055 uses pins 1 and 2 for it's 8V control and ground, respectively, and all others use pins 5 and 4 for 10V control and ground, respectively.

Is the 6095 like the 6055 or like the older ones?

Since I'm not sure, I made a cable that ties together pins 1 & 5 and pins 2 & 4 so that it would work with either style.

Will this work with the 6095? I don't want to risk damaging the powerhead or the Apex. It would mean that pin 1 and 5 both get 0-10V and 2 and 4 are both ground.

They all use the same pins, I think this info came from the fact that some 6055's and 6095's the pins get soldered together but every controllable pump since 2000 uses pins 2 3 and 5 and sometimes 1 and 2 get soldered together, 2 is voltage to the controller, 3 is neutral, 5 is voltage back from the controller.

1 and 4 are never used.

Well, that's totally not what the Apex documentation claims you need in order to talk to a tunze. How are you numbering the pins?

Are you counting 1,2,3,4,5 counter clockwise when they're in a u shape looking at the male cable end or the controller end or are you doing the DIN-5 standard way where the pins go 1,4,2,5,3?

Here's what I'm talking about. In this picture, what pins are being used on the male connector?

 

[rvitko]

I was going counterclockwise with the notch at at the top, using that diagram 4 2 and 3 are used.

OK. Sorry to ask for more clarification. Not trying to be pedantic, just trying to get it. You said in the diagram above that 4,2,and 3 are used. What are 4, 2, and 3 used for in that diagram?

Also, I edited the post with a better picture instead of the white backed diagram. That one had them reversed, so now I'm not sure if you were looking at the original picture or this one, lol. I messed myself up.

4= power to controller-
2= common
3= power from controller

Thanks! Wonder if we can get the Apex folks to update that "comprehensive guide" with the correct info that the 6055 doesn't have a unique pin setup and to get their pin usage straight. They seem to have it pretty wrong in the attached diagram. It would be helpful if they just put a picture of the Tunze female plug and an arrow pointing to the three pins you indicated:

0-10V control in,
8V power out for Tunze controller,
Neutral.

Then folks could wire up their cord however they want without the ambiguity of how the pins are numbered or if you're looking at the back side of the plug or the front side when numbering or etc..

For $20 plus shipping I think I'm going to just order the Neptune cable rather than risk damage to $500 worth of powerheads and $500 worth of controller.
