Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"

Does anyone know whether it is possible, and if so how, to program a GLX-PCB-PRO for specific configurations?

Someone might know, but I suspect that this is going to need to come from a Hayward product engineer or technical specialist.

I would suggest sending an email to Hayward describing the issue.

Someone on the phone probably won’t know this.

The person who gets the email probably won’t know either. However, they will know who to forward it to.

The ProLogic is very similar to the AquaLogic which is what I have. What exactly are you trying to do?

I don't believe there is a way to fool the ProLogic into believing the display is something other than it is. If you have a 16 display it is expecting an expansion unit.

His old board did not give the error. His system is PS-8, but at some point, the display was switched to a PS-16. This did not create an error.

So, I’m thinking there might be a way that they set the board at the time of system assembly. Maybe a hidden menu. If the board was not preset, the new display should have caused the error.

Replacement boards are all the same for all systems. So the board has to read the display type and set accordingly. This is what’s causing the error.

I’m thinking that if they can preset a board to PS-8, then it might work without an error.

There might even be a hidden menu that can change the setting, but I don’t think that Hayward would want to tell everyone.

My system was installed with a PS-16 local display without an expansion unit and I never received the check alert. Must all PS-16 local displays also have an expansion unit?

Do you know if the installer did a factory reset on the board after installation? That can be done through the diagnostics menu. These boards save the configuration in flash so will maintain a previous configuration even when powered off. That is the only thing I can think of that might help.

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"

The reset to factory default in the configuration menu only resets the configuration options available in the configuration menu.

Also, the replacement boards don't come set to a system type. So, even if the reset covered system type, there is no default setting to go to.

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"

Yes but it may have been connected to a PS-16 display with an expansion unit before and retained that setting. Worth a try.

Are you certain that the board can be reset after installation? And, if so, how?

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"

Yes, the board can be reset. Go into the configuration menu and use the right arrow until you see "Reset Config to Default".

See page 32: https://www.hayward-pool.com/pdf/manuals/PLTPM-PL-PS-x&PL-PS-x-VOperationsOct08&Later.pdf

Note that you will need to reprogram all the timers and settings you had before so you may want to copy those down.

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"

The reset is in the configuration menu.

I don't know why they would pull a board out of a different system, but I guess it's possible.

Even if they did, the default would be a PS-16 with expansion unit.

Wherever they got the board, the board automatically changed to PS-16 when paired with a PS-16 display. So, even if it could be reset, it would just revert back to PS-16.

If they used a board out of a PS-8, I suspect that it might work.

So, even if it could be reset, it would just revert back to PS-16. So, even if it could be reset, it would just revert back to PS-16.

Good point! "Reset config to default" may not resolve the pairing of the PS-16 to the GLX-PCB-PRO, if there is a pairing involved at all. Plus the new GLX-PCP-PRO was at default when installed.

 

[JamesW]

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"

I think that they set the board to system type at the time they build a system. Otherwise, someone could buy a lesser system at lower cost and reprogram it to be a better system.

They don't preset the replacement boards because that would require distributors and retailers to carry too much inventory. They would have to carry a board for each system type, which would greatly increase their inventory costs.

So, it makes sense to preset boards when building a system, but not replacement boards.

Hopefully, your service person will figure this out before coming back with a regular replacement board. I think that they would just be wasting their time.

If they consult with a Hayward technical representative, they should be able to figure it out.

It may not but still worth a try in my book. The display type may be saved in the internal settings when first connected and can only be removed by a reset.

Warranty boards are sometimes re-manufactured or open box. It is quite possible that another tech used that same board to troubleshoot another system.

This is all speculation but you never know for sure until you try.

Could virtual mode be the solution? I know that Hayward puts out virtual PS-8 and PS-16s. Would a virtual mode configuration not look for the expansion code?

 

[JamesW]

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"

That might work. However, the issue is how do you change the setting?

If you could change the setting, then you could change it to a PS-8.

Also, I'm not sure which display the 16-V uses. I think that it might use the PS-8 display.

I'm pretty sure that Hayward has some programming things that they could do but probably don't want to make public.

Probably the easiest thing would be to have Hayward preset a board to PS-8 and send it out to you or the warranty service people.

Right, how to change the setting? The 16-V uses the PS-16 display. The "virtual" applies to extended soft keys that can be programmed but do not control actual relays because there's no expansion board. Still awaiting back-ordered board but if I could figure out whether it's possible to configure the system to virtual mode then I believe the problem would be resolved.

 

[JamesW]

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"

If the back ordered board is just a regular replacement glx-pcb-pro, I don't think that it's going to work.

Also, how do you know that it uses the 16 display?

I think that it uses soft keys because it doesn't have actual keys.

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"

Agree. I found a chart here: https://www.hayward-pool.com/pdf/literature/automation-brochure-LITAUTOB14.pdf I don't believe a PS-16 display can serve as a virtual PS-8, but if you know otherwise then I'll work that angle.

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"

Well the problem has finally been resolved! My GLX-PL-LOC-PS16 (local display) was causing the new circuit board (GLX-PCB-PRO) to generate the "Exp. Unit Software PS-16 Comm Error" because the PS16 was expecting an expansion unit. The PS-16 always comes with an expansion unit but the PS-16V (for virtual) does not. Since I did not have an expansion unit in my set up, the original installer had to have done a special override of the PS16 for it to act as a PS16V and not generate the alert. (I have no idea why he used a PS16 and not a PS-8.) Hayward would not provide me with the over-ride sequence but did provide it to the warranty provider. It worked, and the check system alert was eliminated. So if anyone is installing a GLX-PCP-PRO into a box with a PS-16 display but without an expansion unit, they need to understand that an alert will be generated unless the PS-16 is reset to act as a PS-16V. Of course this is a very unusual and unlikely circumstance, which "lucky" for me I got to experience.

Thanks to those who helped give me the resolve to follow through with this. I wasn't looking forward to constantly blinking check system alerts.
