Blinking green

[Cali9dub]

@Vinny@GHLUSA my P4 is blinking green however I don’t dose (I have a KHD which is disable in the app). The only other thing attached is a pressure switch for my skimmer waste that will flash red when it is activated (skimmer waste full). Any idea what can be causing the green blinking top LED ?

yeah. I read those. However I have NO activity going on, like I stated. Any other suggestion ? Is there anywhere that indicates what the mystery activity might be ??

Is the P4 talking to the pressure switch - and if so the case - how

Not sure what you mean. It’s in the same port it’s been in for the past 5 years. The purple din

When the pressure switch is activated (the skimmate waste is full) it turns off the skimmer. It is working as it should. It’s been set up for years. Not sure why suddenly I have a green blinking light. No setting have changed at all other than adding 3 more power pars. They are all hooked up and assigned but the only outlets being used are “always on” none programmed yet. All the outlets have been numbered correctly.

pressure switch

I´m sorry - but I do not understand what you mean with a pressure switch. I´m not aware that GHL have any pressure switch in their sortiment - I only know of the floating and the optical switches.

Have you update your FW lately?

If you activate your KHD - does it still blink? Do you have any dosing pumps attached to the KHD?

The pressure switch is from avast marine. GHL doesn’t have one, but anyway…there is a dosing pump attached to the KHD. I didn’t try activating the KHD. I’m not currently using it or the SA doser. I guess I can try activating it and see what happens.

If I understand you right - have you the KHD and the SA doser connected to your P4 through PAB connection but not the KHD activated? You write SA doser - if it connected to the P4 trough PAB - is it in slave or SA mode.

Sorry for all of the questions but I´ll try understand how your system is fitting together in order to understan why its blinking
