Adding a Second pH Probe

[thewbell]

I have added a second pH probe for my calcium reactor and named it pH2 using the Apex display. I have pH2 showing up on my Fusion Dashboard as well as an option on the PH control wizzard but I keep getting an error when I try to use pH2 in my programming. Any ideas?

Here is the code I am using and the error message I am getting.

Fallback OFF
If pH2 > 7.0 Then On
If pH2 < 6.9 Then Off
If pH1 < 7.8 Then OFF

Send Failed

Change the name of the probe to something like pH-CaR

Im having the same problem. Tried Russ' s suggestion with no success. I can see pH2 on the display and have calibrated it, but when I try to send the program to the Apex it comes back with same error as thewbell.

Did this ever get resolved? I'm having the same problem. I've used pH2 for years with the Classic Apex and I've been having this same problem for the last few weeks.

My issue was resolved when I changed the probe name to pH_CAR but I never could get pH2 to work.

I'm new to the controller world. I have a CaRx and plan to use the ORP port on the Apex for the second pH probe. Ive been looking at Fusion and trying to understand how to change from ORP to pH2 or pH_CAR or pH-CaRx as previously mentioned, and I don't really understand how to change. Any direction would be greatly welcomed.

Simply go to the Inputs page in either Apex Fusion or Apex Local, and enable pH2; this will automatically disable ORP.

Thank you Russ. I'll give that a try when I get home this evening.

Worked like a charm

I do not know where your finding ph2 at. It's not on the task list or dashboard. I would like to add the ph probe for my cal reactor. I have tried disabling the ord probe and renaming with no luck. Can you walk me through it please?

go to the Inputs page in either Apex Fusion or Apex Local, and enable pH2
