Clock / Time and Date Resetting

[Matrix]

Every since the Time change here last Sunday morning,  the Classic keeps changing the Date and time.  I set it from the local app (have sync off) and a few minutes later it goes back to whatever, with a day of like 09/12/2012.  I have also set if for the control panel on the classic.

Why is Date and Time doing this now?  I have not had a problem for almost 3 weeks until this past Sunday.

I am trying to remember if the Classics come with some plastic in the MNGP battery that you need to remove. That battery is what holds the time if you remove power from ( unplug ) the MNGP .
So you should check that -- you pull black plastic cover off MNGP - also make sure your speaker is pluged in there .

Yeah it did have plastic ... but I removed it.  But so far today it is holding time for the past 20 hrs. 

But I have 4 days that are now messed up date wise ... and so they are sending the wrong info to PV Output.   Is there anyway to Edit the log file in the classic?

Delete the logs and start out fresh is probably the best approach .

Good post , Or the small battery cell might of died ?

I know this is an older thread I started late last  year,  but this issue still is not resolved. 

Every time I power down the Classic 150,  (that is turn off the array and then turn off the power from the battery bank),  the Time and Date reset to 2012 or something about then.  All other settings get retained,  but time and date are always off to the same past date.  And it has happened every time this year too.  I have several different days of power down for system wire changes, and it happens every time.   I replaced the battery inside the CC about 6 weeks ago.  Still no improvement. 

Any ideas,  or is this just the nature of the 150?

I believe that the clock set in the Local App was put there to assist people with Lites. Since Lites do not have the MNGP and the battery that retains the RTC clock when power is lost. There is another clock in the Classic but it does not have battery backup and the MNGP sync with that clock every so often. You have to have Time Sync ON. Try it nothing to lose if I'm wrong about all this boB can set me straight or anyone with a better understanding than me.

Did you check the voltage of the small coin cell  battery in the MNGP ?  Or change that battery ?  It might be bad.

Each time the Classic is rebooted, it must be resetting to its original time and date then

If the Time Sync is disabled from the MNGP, then the Classic won't get the time/date from the MNGP every minute or so.

There is a crystal and Real Time Clock/Calendar in the Classic itself but if the power is removed, then it will reset to
that 2012 default when the processor reboots.  Then, it will either stay that way until told differently by the
Local App or the MNGP if that Time-Sync is enabled.


You can read the time and date in the Classic itself from the MNGP's TIME menu.  In that menu, hold down
the LEFT ARROW key while you tap the UPPER RIGHT soft key and it should read the time/date from the Classic itself.

In the MNGP TIME menu, if time-sync is turned ON, pressing the ENTER button in the TIME menu will send that time/date
to the Classic right away.  Otherwise, when ON, the MNGP will set the time/date from its battery backed-up clock
around once per minute.

I thought that the un-set date-year in the Classic itself was year 2003 (different that the unset MNGP year, 2000)
but I just checked my office Classic and it came up as 2012 and then 2010 when I unpowered and repowered it
right after.  This Classic has been running on a power supply for several weeks now but I don't remember if I
ever set the time/date on it.  I think that the battery piece of insulator paper was still in the MNGP keeping the
battery out of circuit.

You could theoretically change the LOGS time-stamp but if you don't know what time or date that was exactly,
then it would be pretty hard to do.  But since you know the logging interval, once you know one of the times,
the others could be inferred to that.  OR, you could change that in the CSV file I suppose.

It may be that you just have to have something to set the Classic's time and date every so often to keep it
accurate.

Hopefully I haven't mis-interpretted your issue too much.

Absolutely correct RH !

So I would do better to use sync rather than the Blue left arrow in the local app?    Usually I just reset all the date and time,  and they press the blue arrow.   I do not use sync in the local app? 

And what is this saying (from the local app)

Disclaimer: To use this setting you must have a Classic Lite or Time Sync OFF on a standard Classic

Is there another place in the local app to turn time sync off and on?  I have a standard classic.

[Resthome]

Turn Time Sync on in the Tweaks Menu 4 on the Classic itself.

I have know idea what Andrew was trying to do with the sync turned off.  And I don't know what his SYNC button does unless it tries to sync the two RTCs but why turn off Time Sync?  If it is off as boB said when you power off the Classic it will not get the time from the MNGP that has the battery back up.

I'm pretty sure if you set Time Sync ON on the Classic itself you wont have any more issue with the time resetting back to default.

There was a issue with the little metal prongs than contact the battery having some kind of glue from the paper that was put in at the factory to save the battery. But doubt that is you problem.

[boB]

How often does the Classic go off and on ?   And does it do this by way of auto-reset or  is the battery power being disconnected and re-connected ?

I think that if the Classic just gets reset and the power doesn't actually cycle that the Classic's time and date should stay as it was through the reset.

The issue with the Local App setting the time is that you have to manually tell the Local App to set the time.  I don't think it will do it automatically.

Yes, the MNGP is where you turn on and off the time sync because it is what typically tells the Classic what time and date it is.

Thanks,   classic goes on and off about every 10 days or so.  Depending on what I am setting up and rewiring.  Next possible rewire thing might be an auto transformer.

But i will try turning on sync on the MNGP.  thanks.
