Fan/AGS

Post by gasjim » Tue Sep 03, 2019 4:56 pm

Hey experts! I have a relatively ancient system (installed in 09, I think) which is actually running great. 60 cycle, 24 volt system. Today (a hot day) I had a problem. When installed, I used the Aux power output to drive a relay for to start a generator, using the Mate's AGS commands. Works great. Today, the system wanted the fan to run (never hooked up) so it triggered the relay and ran the generator. Is there a way I can tell it to not run the fan from the Mate? Any other work arounds? I wouldn't hate to hook up a fan, but again...only have the two aux wires to work with and the system is designed to need/use a generator. I am open to suggestions!

Do you have both a fan and the AGS contact wired to the same aux relay? If you have an Outback charge controller then perhaps you could utilize its aux contact for the fan? Or vice-versa...

Can you further elaborate on your system components and which device's aux relay you're using? If you're referring to the FX's cooling fan option for the aux relay then if you have a Mate3, FM60/80 and a hub you could use the FM's aux output to start your gennie, per this quote from the FM80 manual:

"NOTE: The Remote option allows the MATE3 to use the AUX output for AGS. AGS is intended for systems with a HUB, inverter, and FLEXmax. If the MATE3 connects only to a FLEXmax, AGS will only work with DC genset programming. The other AGS functions will not work properly."

Again, sorry for the dumb questions. - Mike .

Mike! Thanks for the quick response. No, your questions are not dumb...I really didn't lay out all the info. OK...I have an FX 2524, Mate 2 and a MPPT 60A charge controller. I currently have the AGS function using the two aux outputs on the FX. This has been working happily for several (10ish) years. Yesterday I noticed my gennie was running in the middle of the day. Went out to check and noticed that there was an error light on the FX. Paged through the Mate and noted that it said yes to the "unable to start fan (or whatever it said wrt the fan)…" The relay to start the gennie was triggered.

This is the first time (to my knowledge) that this has happened. It wasn't particularly hot outside nor in the shed where the system lives. I was hoping that someone would say...oh, just go into the mate and turn off the fan control...or something. The only workaround I can see would be to just put the generator into off mode during the day and hook up the fan wires in the FX (as well as the relay for the generator). It isn't a catastrophic problem to do that...we are out there several times a day (this system basically powers our greenhouse...Swamp cooler and fan, more or less)...so could pretty easily add it to our routine. But it seems inelegant. Which is why I am asking here...Thanks!! Edited to add that there were no other warnings or alarms...overtemp or anything of the sort.

Okay, that helps. Is it possible the AGS start was proper (i.e., the battery needed it) and it just so happened that the FX cooling fan (assuming that's the fan that would not start - is it?) failed at the same time? I ask this because it seems doubtful that the AGS start is related to the fan failure.

Another question - is the internal fan on your FX working? That may be the extent of the problem.

Good point. No, this was not an AGS issue. In fact, I put the AGS on the mate to manual off and the gennie kept running...relay thrown. I bet, however that you are right...the internal fan has probably died. Fixable? or do I need to go ahead and put my backup to work? I have another FX "on standby" which I can go ahead and install.

This thread viewtopic.php?f=17&t=13908&p=63592&hili ... ace#p63592 includes instructions on replacing an FX fan. Sounds like it's not hard.

Cool beans, Mike! Thank you so much for helping me out with this deal. I'll hook up my spare inverter and contact outback for the stuff to rebuild the other one. Excellent outcome! :grin:
