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

[boB]

But  65  (decimal) is   41  (hexadecimal).

So, when possible, tell your age in hex rather than decimal.

Hi boB, re Temps, were you after current temps? or is there a historical listing?

If this was regarding the yellow LED, probably the temperatures read at that time would be great.
PCB temp and FET temp.

Sorry, did not read them at the discovery of shutdown... 
BTW the fans have not come on AFAIK except at powerup/startup.  Basement is a cool 8*C pretty much full time till summer heat starts

You can read the Hi FET temp history in the Daily Logs, but not the PCB Temp.

FWIW,  one Classic 150 here also went to rest,  Mode = Off.

This occurred while this Classic was in Absorb,  delivering about 20 CC Amp  (about half way through Absorb in time),  WHILE I was navigating from the Main Status page to the WBjr status page.  Heard the input relay open,  went back to the main status page,  saw Classic resting,  mode off.

RFR was 104.  Looked like the Classic went through at least part of a boot phase,  with the LEDs inside the front vent were swept,  and,  IIRC,  the Amber LED on the front left,  believe the Limit LED went on.

48 V system,  String Vmp = 106 V
Classic 3677  FW 1772
MNGP FW 1608

The ambient temp was about 64 F.  Vin was probably about 108 - 110 V.

Did not look at any of the Classic temps

Have never seen this in any Classic here.

Should UD the MNGP FW at the least ...   Thanks,   Vic

Vic.. the current beta FW has updates for Classic, MNGP, & Network that seem to be pretty stable here. Classic 1849  4/21/14, MNGP 1821  4/14/14, Network 1839

boB has been working hard to resolve a lot of the 104 Watch Dog Timer reset.

Hi John,

Yea,  have little to loose in doing updates to the Classic and MNGP ...  should have mentioned that I have not ever used the Local App.

Had followed much of the conversation about Resting events,  but somehow I had missed that these events were Mode Off events.   Realize that if the Classic is Resting,   it is not delivering power at that time,  but had FELT that the Classic might/probably would recover on its own,  at least,  in time.

Mode Off means to me that the Classic has no mechanism to recover to Mode ON,  on its own,  requiring manual intervention.

The system mentioned above is at a residence location,  and  is usually attended,  and therefore,  there is a good chance of a human intervening,  usually with no more than three or four days delay.

Anyway,  will probably do FW UDs in the next few days,  thanks for the guidance.     Vic

Vic the HI FET temp is found in the Classic LOG menu under Daily so you can go back in time to see a historical view for each day. No need for the local app.

Hi John,

Saw that you mentioned that FET Temp is avail in the Log earlier in this Thread ...   expect that this was not the issue.   The A/C in that power room was on MAX,  and the temp there was 64 F ...  and the Turbo Fan just never runs.

The Vin on this system is a bit high,  so CCs run a bit warmer than most.

Will try to look at the Log to see ...  customarily,  the FETs are not so hot.

Thanks again.    Vic

At peak bulk I see my FET temp around 45-46 C with the Classic pushing around 50A.

Andrew, my question about the PC recognizing a 'new device' has been connected to the PC seems to have got missed in the other chatter...

I got to step 13 in the FW install instructions, and the PC does not 'ding dong' and say ' New device  or whatever'  is connected...  it just does not 'see' the classic connection at all.

Any ideas as to what I can check?

tks

If you have done firmware updates with this PC before the driver is already installed and you shouldn't see this step. Only happens with a new install. I just go to step 28. If you have never install the firmware updater on this PC then you might want to try another USB cable from the Classic to the PC.

[Westbranch]

Hi John, this is the first time through the process's of either FW update or LA use.

The USB cable is the one supplied by MN and I think is > 2 feet (it is still partially coiled/tied for neatness).  I got the same 'no response' from both classics, separate cables,  so I did not suspect the cables.  Bad install of GUI?

WB, what is your OS again ?
Windoze ?  *nix ?  etc ?
