Classics Found in "Mode is OFF" mode

Twice now I have found classics in the Mode OFF mode when I rolled up to troubleshoot other problems.

Customers think their batteries must be bad, or that their generator runs too much.

Is there possibly a bug (or feature) that could cause the CC to go into this mode by itself?

Both installations are of people who are not used to being off grid.  But not likely to push buttons themselves, either.

Hi Ron,

Have never seen this situation,  have been running Classics for 8 years,     but ...

It is VERY IMPORTANT  that if anyone changes a Mode,  that Enter is pressed.   If this is not done,  at Midnite,  (with  Arst is ON),  that the the Classic  will have Mode set to OFF on the following days.   Not a bug,   and  seems consistent,   when one thinks about it.

The first time or two,  is seems easy to NOT REMEMBEER to press Enter after change any Mode.

Just my experience,   but not a Bug IMO.   FWIW,   Vic

Vic ,
I turned the auto reset at midnight off a month or so ago. Seems like all the bugs that we used to have that on for are now fixed in latest firmware updates.

It shouldn't turn OFF unless, like was mentioned, the Classic was set to Mode OFF and then ENTER was entered without it being turned back ON and ENTER pressed again.

Here is a sanity check...

Turn the POWER to the Classic OFF and let it restart/reset.  Does it come up  ON ?  or OFF ?

If it comes up OFF, then go to the Mode menu, turn it ON and press ENTER and make sure the display says the command was saved.

Then turn the power ON  again and see if it comes up as ON.   

If it does not come up as Mode ON, then something is probably wrong with the Classic.

I don't ~think~  there is another way, other than external control, that can turn the mode OFF other than loading the wrong code to it during a software update.

I will think if there are other ways but I don't remember any off hand.

Well, I have learned one thing from you guys and that is the importance of pushing "enter" to have it write the data.

I have always done it that way but did not know what the significance was, now I do.

With the talk about cycling/resets.  Both of these locations have flaky generators and have been known to run out of battery power often.  Both are 24V.  How low would the battery voltage have to go before the Classic reset or something?

Seems unlikely because IIRC the Classic can even work on a 12V system right?  And these 24V systems would never have gone much below 22 before LBCO.

Just grasping at straws, trying to find a common theme here.

The Classic should stay running down to around 5V or so but right, unless the batteries went completely flat, the Classic "shouldn't" reset.

However, the Classic has a computer in it and although it's not "Windows", it can still reset due to whatever(?) condition might cause it to do that.
Could be lightning, stray cosmic ray or alpha particle, random "glitch"  or maybe the Auto Restart was enabled. 

But if the internal nonvolatile memory (EEPROM) knows that the Mode should be ON, the Classic will come back up with the Mode in the ON mode.

BTW, if one looks at the Reason For Resting codes, RFR of 16  means that the mode was turned OFF by the user BUT that would have to be the last thing that made the Classic go to Resting because the RFR code would get overwritten be any newer reason like low light.

Please let us know what you find.  That sanity check of turning the power off and letting the Classic reset should tell the story... Hopefully...
