Over the past day I have gone "live" with RA on my reef tank. The problem I have is that for some reason I get an ATO alarm (red led on), and RA shuts off my lights and skimmer, which are the options to be turned off for an over heat situation.
I know that the event is not an overheat as I am using the tank water temperature set to 85*f as the overheat point, and the client suite tells me that the temperature range over the last 24hrs has been min 78.4*f and max 81.7*f.
I am using two float switches in series (one set above the other) connected to ATOlow port. I also only have the ATO port live for six periods of on hour per day, 00:00 to 01:00, 04:00 to 05:00, 08:00 to 09"00, 12:00 to 13:00, 16:00 to 17:00, 20:00 to 21:00.
I am also using ATOhi as a PMW output to drive a 5v DC SSR. This controls the mixing pump in my Kalk reactor. As I need to have a settling time for the kalk before I pump water through the reactor into the tank from my RO/DI reservoir, whan the ATO kicks in, ATOhi is available six time per day for half an hour. Starting 30 mins after the ATO period has ended. i.e. 01:30 to 02:00 etc.
(The above has been part of two other postings by myself, and commented on by Roberto and Binder)
Under test I did not notice this happen, but I was not running the ATO sensors or the SSR on ATOhi all the time. I just tested that they cam on and went off at the right times by changing the clock time.
I believe the problem is to do with the use of ATOhi as a PWM output, as the turning off of the lights and skimmer happens during that period. I have set the time out for that port to 255, but as I am not using it as for ATO sensing, it did not make any difference.
I don't understand why I get an overheat shut down caused by an ATO alarm call, and also why I ma getting the alarm in the first place?
I can simply resolve the problem by moving back to time switches and not using the RA, and my have to do that while I fine a solution. But that kind of goes against the grain
Any ideas?
I am running Dev. Libs 0.8.5.19, and here is my PDE file.
