Apex Variable Speed to AQLink A1

[firebladeRR1k]

I recently purchased an Apex controller. I have it all set up and everything is working well except for my flow pumps. They are 2 Coral Box QP9+ pumps connected to the apex via 2 AQLink A1 units to the Variable Speed ports on the Apex. The issue I have is no matter the % sent to the pump from the apex the pumps spin extremely slow. I’m using standard Ethernet cords to connect the A1 to the Apex and have even swapped them out. I have tested the Variable Speed voltage also and it looks fine. Any help would be greatly appreciated.

Forgot to mention that if I put it on an on off flow it turns really slow and then stutters a bit. Even putting it on 100% runs really slow. If I manually turn off and then on a few times slowly the pump will start running at the correct speed.

also, the pumps work fine with when used with their original controllers.
I have also verified the dip switches on the A1 with Coral Box.

Any chance you are programming the wrong variable output? There are 4 variable outputs, for 0-10v. They should JUST have "Set 100" if you are trying to test maximum percentage.

Edit: I guess you said that you tested the variable speed voltage and confirmed it, so you do have the outputs correct.

There's some info at the Neptune Community Forum that might help: https://forum.neptunesystems.com/showthread.php?17394-Aqualink-A1-(Jebao-Gyre-Controller-Adapter)

In particular, pay attention to the part about running the pump in reverse.

I have pump 1/AQLink 1 plugged into variable ports 1/2. Pump 2/AQLink 2 plugged into variable port 3/4. I have port 2 & 3 set to off. 90% of the time I turn port 1 & 3 to on the pumps run super slow. I have tried swapping the cables and the AQLinks between the ports and pumps. It’s almost like the pump was running at 1% (really slow). When on a 1 second on 1 second off profile the pump spins slowly and just twitches when it should have turned off.

Thanks for the links above. I read through them and I think I’m doing the connections right. At this point, I’m at a loss. I was super excited to finally get an Apex but then having these problems with the pumps is a big bummer. I’m hoping someone has run into something like this and has an easy solution, even if it’s faulty hardware.
