Classic shut down: MODE = OFF Orange LED on MNGP blinking

[Westbranch]

I returned to the cabin for Easter and went to check my 2 Classic 150's,
#1 was fine and happily in Float by noon
#2 however was not so happy as it has shut down , Mode = OFF showed on MNGP and the bottom LED was Blinking Orange. 
Jeez, no internet available and didn't bring a  laptop..... and a flat battery to boot

Off to the closest neighbour (5 miles) with internet , On Line manual states Blinking Orange indicates that there was an Over Amperage event 

I am puzzled as there are ONLY 2 140W (12V 8A) panels in series  and the CC Output was set to 90A and the Input set to 55A.

I reset the mode to ON and reset the battery charge parameters, it had defaulted to 12 volt settings.

Appears to be functioning OK for now.

Cl serial number  # 647, sorry could not remember the key strokes to retrieve the FW version.

Any ideas?  stumped here

That blinking LED could mean it has either reached the current limit (unlikely with your small array)
or it has gotten (or thinks it has) gotten too hot.

Maybe it just thinks it is hot ?  Check the FET and PCB temperature readings.

Another thing that might (can't remember off the top) to make the orange LED come on is
over-voltage on the PV input which is also probably unlikely.

Check the PV voltage and temperature readings just for good measure.

Are you sure its the amber LED blinking? The bottom one? I can not say I have ever seen that one blink.

thanks boB, I will try to do a temp log  for a few hours next visit.

Ryan, for sure it was the bottom LED, Amber (or Orange) at the bottom of the MNGP, left side.

Forgot to add:

that the CL647 is a refurbished unit;

All 3 LEDs inside were in Blinky mode;

the CC had reset out of Solar mode as well (forget to what though, P&O?), corrected that too.

Ambient temps in basement were well below freezing all winter!  -5C to -30C

Did you check the Reason For Resting ?

ReasonForResting = 27  is one in earlier Classics that can cause the MODE to
turn OFF...  but yours may be a bit too old for that if serial number 647....

   Can't remember when we added R132.

In fact, check this drawing and see if this resistor is in your Classic.

Another reason that the Classic can turn the mode to OFF is if the wind graph is
bogus and has a current step that is higher than 99 amps.  This could happen
even if your Classic was not in wind mode.   BUT, your Classic came back on so
that is probably NOT your problem.

Please check for R132.  I don't know why the LED would be ON or blinking though
for that reason but it could make its mode go to off.

boB, the only info was the PV and Battery voltages/amps and MODE = OFF.

There was no REASON showing on the main screen, so is there a way to 'drill deeper' on that machine to find the REASON?

Oh, and the 'internal Leds were cycling 1on, then 2 on and then 3 on, and then repeat (BLINKY mode?)

boB, re the presence or not of that R123:  If the pins are not showing,  the resistor is absent?

In the pic, it looks to me that there are 2 soldered pins, right?

thanks.

To enter the reason for resting  screen from main status...

Hold down left arrow key and then press the enter key

[Westbranch]

thanks RH,  I remember reading something about that before, just old-timers brain prevents it floating to the top....

Do you know how to get to FW version etc.?

[Vic]

   ...   Do you know how to get to FW version etc.?

WB,  just keep tapping the Status button,  the page for FW version(s) is about the seventh down,  or so.   There are other ways ...  believe that it is also displayed on App.

[Westbranch]

thanks Vic, I don't have a functioning laptop right now so I cant use the Local  App.

I should now be able to get the needed details to help solve this one.

Hope to be back out next weekend and finish a bulk gen charge.  Some birthday present! 

[Vic]

And,  WB,

RH John is correct about the RFR.   There MIGHT be a distinction between "pressing",  and tapping the Enter button.  In the past,  boB  has mentioned "tapping" Enter.   It is possible that if one held the Enter button for too long that it might change the state of the Classic (?).

Here is a Thread regarding RFR -- Reply #1 from boB explains the page that contains the RFR number:

FWIW     Is your off-grid site  with the subject Classic prone to Spring lightning incidents?   And,  do you recall updating the FW in this Classic after you received it?   The Refurbed Classic here had the current Production FW as of the time it left MN,  after the repair.  Good Luck,   Happy Birthday!  Vic

[Westbranch]

thanks Vic.

from the main status menu, HOLD down the LEFT ARROW button and TAP the ENTER key.

You will see a screen with some numbers on it with IN on the left and OUT on the right.  What you want to take note of is the number at the MIDDLE-TOP of the screen.   That number will give an idea of why it went to resting.
That number will always be active and represent the last time it went to resting.   i.e., the number will not get erased if you don't look at it right away.

Right from what boB and RH said and your comments, I should be able to retrieve something.
I also found boB's  list of Reasons   via a search for ReasonforResting" here

Re lightning, no we do not get much.  I would have expected both Classics to have been affected as my small maintenance arrays are on the S wall and within 1 foot of each other and the wires to both Classics are closer than that. Both banks sit side by each ~ 1 foot apart, I immediately thought of that potential but after a short self talk dismissed it , if it hit one, the other would have been hit AFAICS
NO lighting protection installed so far, SPDs in a box at the ready...

YUP, officially an old fart now... what the heck, its the new 45 as my wife tells me before reminding me to slow down...

cheers.

Tks boB... 65 is the new 45,  ya that expression was found in Zoomer (Canadian) Magazine by SWMBO and she keeps reminding me SHE isn't there just yet!
