Pentair Valve Expansion Board (522038z)

[Poolover]

I just added the valve expansion board in my Intellicenter and can't seem to get it to work. BACKGROUND - I'm currenting running two laminars off the Valve A and Valve B connectors on the main board (using Intellivalves). I had no problems installing the Intellivalves, configuring them (setting end points), configuring the software (designating the valves and creating features to control them in the app). So, I can turn on/off those water features from my phone (app)...AWESOME/GREAT! Now, I wanted to control my bubbler. Added the expansion board - connected it to my personality board (i8PS), slid the board in (made sure it was seated correctly), added the 2 retaining screws, connected the Intellivalve...and nothing. The LEDs on the Intellivalve did not light up, nothing...like no power? So, to trouble shoot it...and make sure the Intellivalve and wiring was OK...I plugged in this new Intellivalve into Valve B (where I had the working laminar). The Intellivalve LEDs lit up and worked fine (I configured everything and it worked great). So, the Intellivalve was fine and the wiring was fine. Plugged it back into the Expansion Board (Valve C) and nothing again. Tried the other valve connectors on the board (Valve D-H)...still nothing. Rebooted the Intellicenter...still nothing. What's also odd, I can see in the software where you configure the valves...I can see the new valves (Valves C-H) and select them (when the expansion board is plugged in). I double checked to make sure the new board was seated correctly and when it was not plugged in...Valves C-H did not show-up in the software...but when the board is present, you can see the valves in the software.

HELP - Am I missing something...or do I have a bad valve expansion board?

THANKS for any info and help!

Welcome to TFP.

Show us pictures of your IntelliCenter boards.

I'll have to post pics tomorrow - I'm not home at this time and it will be dark when I get home.

 

[Poolover]

Here are the pics of the boards.

This 80uF capacitor leaning over does not look right. Was it that way when you got the board?

@rstrouse has 8 Intellivalves in his IntelliCenter. And let's add @MyAZPool @John_and_Val to the party.

I suggest you call Pentair Support and probably return the board as defective.

I put this pool in this summer (2024) and did a majority of the work (80%). There were two things I didn't do...the finished concrete work around the pool (pool deck) and the screen enclosure. Here are pics of the equipment pad. I selected all the equipment and did all of the plumbing and electrical work. I have appreciated TFP and learned a lot over the last 10 months (did a lot of reading).

Nice work.

Did you put a bead of silicone around the seam on each IntelliValve? They are not well sealed, and water gets inside and corrodes the motor.

Yes, this is how I received the board. I can double check the leads coming from the capacitor and the solder pads, but I think everything looked OK. Often times larger capacitors are bent over (for added protection) so they are not "whacked".

So they are pre-whacked?

Yes, I applied silicone around the joint/seam and some into the end of where the wire comes out (water can wick anywhere it wants). I read your post from before (and tear down of the valve)...very helpful.

I just checked mine and it is also bent. The other direction and not as significantly but as long as the contacts to the board aren't broken, I don't see this as an issue.

Jeff,
I'm assuming you plugged in the expansion board, connected the Intellivalves, and they powered up right away.

With checking the Intellivalves (and wiring) on Valve B...and everything worked...I'm pretty sure I have a bad valve expansion board.

Thanks - Tony

Is anything suppose to be plugged into these pins (see pic)?

 

[ajw22]

The IntelliCenter Installation Manual refers to the Valve Actuator Installation Guide (P/N 270140), but I can't find it online.

 

[Ahultin]

Correct me if I'm wrong buy as I recall, valves 1-4 are controlled via i8ps, the expansion board adds 5+
I'll go look at mine shortly but am reasonably certain

Looks like you are using an i8ps as an i8p, i can't imagine that being an issue in and of itself, but I wonder if there is a setting conflict somewhere?

Unfortunately it has been too long since I added to mine, but I am sure that is exactly what happened.

Nothing is supposed to be on the jumper pins in your other post.

Correct - I don't have a spa (at this point, possibly in the future), so I'm running in a "i8p" like configuration. As for settings, I believe I have everything setup correctly, but is there something else I could be missing?

I installed the valve expansion, ran thru the install wizard and then all worked.
As an additional confirmation to make sure it's a valve expansion board problem and not a pass thru issue on the personality card :
1. Have you confirmed the intake and return valve headers on the personality card have power?
2. Since you are using "pool only" back up your configuration to a usb drive the. Try temporarily removing the personality card and install the valve expansion card to the i5p main board and see if you get power to the valve headers.
