Incorrect Engine State: Cooling Down

[ColtB45]

I've got a 7030 (HW v1.06, FW v1.19) with a Evolution controller that incorrectly reports a state of Cooling Down while running in an outage. It's the only one I have seen do that.

It does briefly go to Running, but then (during a 3 hour outage) stays on cooling down for the duration. Once utility power is restored it goes back to running, and then Stopped.

As a minor aside, it also sends all emails except 'Utility Power Restored' in duplicate.

Hi @ColtB45,

Are you seeing any communication errors (see the Monitor tab in the web UI)? This could cause problems with the registers updating correctly.

Once the generator runs due to a power outage, and once power is restored, the generator continues to run in "Cooling Down" mode. Can you validate with your Outage Log that the power was not restored when the generator was reporting Cooling Down?

Do you have a "smart" transfer switch? This is one that will monitor the incoming utility voltage and signal the generator to start. With a "dumb" transfer switch, the generator controller monitors the utility voltage and signals the transfer switch to switch the relays so the house is powered from the generator. The dumb switches are more common.

Also, can you send the contents of the emails in the order received along with the contents of your outage log?

The engine state is reported in register 0001 via the GetEngineState() (@ line 2825) function in genmon.py. Four bits in this 32 bit register report the engine state. The generator controller also reports the status on the Evolution display so it is really just a matter of matching the bit changes to what is on the display.

A good test would be to do a "Run and Transfer" while monitoring the front panel of the controller. If you are setup to receive emails you should get an email every time Register 0001 changes.

It is pretty simple logic so a fix should be easy in terms of code, however I just want to make sure we have things right in terms of the bit patterns from register 0001 and determine if this is a one off exception to the way the code should handle it and what is unique about this system so we can hopefully account for that in the code.

[jgyates]

Thanks for the emails, it looks like you are getting duplicate emails for "Generator Notice" does this always occur? You should only getting "Generator Notice" emails if register 0001 changes state. It looks like you are not getting duplicate emails of Power Outage Notification. Is this generator using 2 Wire start (i.e. some other device is signaling the generator to start)?

[ColtB45]

Hey @jgyates ,

Thanks for the quick reply.

Comm Errors: I'm not noticing any. This is from the monitor tab:

Monitor:

Genmon Stats: 
    Monitor Health: OK
    Generator Type Selected : Evolution Controller, Air Cooled
    Generator Monitor running for 2:32:30.

Serial Stats: 
    PacketCount M: 279386, S: 279385, Buffer Count: 0
    CRC Errors : 0  Percent : 0.00
    Discarded  : 0  Restarts: 0  TimeOut: 0
    Packets per second: 61.07
    Average Transaction Time: 0.0316 sec

Validate the outage: I can confirm the entire duration, except for a brief period in the beginning and again at the end, the generator was running and genmon was reporting cooling down.

Transfer Switch: It has a dumb transfer switch.

Emails: You got 'em. :)

Outage Log: The Outage log is destroyed. :( I run on a non-persistant install that is wiped at reboot (overlayroot). I had rebooted when updating genmon. I can definitely save it in the future.

Testing: I can probably do that later this week. This is a fairly remote EMS repeater and it takes a fair bit of effort to get there.

[ColtB45]

@jgyates I always get duplicate Generator Notice & Outage Notice emails but not duplicated restored emails. It's worth noting this doesn't happen on the other installs. They don't duplicate emails or send incorrect notices.

This is a brand new (< 2 month old) genset. Possibly newer firmware causing issues?

I have no knowledge of a 2-wire type device. I think it's a pretty standard install.

[jgyates]

Sounds good. One other thing we can check is the logs in /var/log. If you have them. I know you said that your system is overlayed, but just thought I would ask. If you have them we would want to see genmon.log, myserial.log (probably empty since you report no comm errors) and mymail.log (odd that you are getting duplicate emails).

It sounds like you are using this on multiple generators, which is great if you are since we can narrow down the differences easily. If you are are all of the generators the same model or are they different models?

Another thing we can do to test is have the software monitor register 0001. genmon.py has the ability to monitor retisters and send an email when they change:

On line 294:

    self.PrimeRegisters = {
                "0001" : [4, 0],     # Alarm and status register

Change the last zero to a one like this:

    self.PrimeRegisters = {
                "0001" : [4, 1],     # Alarm and status register

Once you make this change and restart it will send an email every time register 0001 changes.

[ColtB45]

I will grab those logs next time. I suspect I can do that by initiating a transfer in-place of a real outage? I wont be able to confirm on the controller but I would have the logs.

We have genmon at 3 tower sites (about to be 4). Anywhere the generator is compatible. All are evolution controllers but different models and ages.

I'll try monitoring register 0001 and let you know what happens.

[jgyates]

Yes, transfer in place should do everything a power outage does except send power outage notification emails.

thanks for the feedback and testing. This really helps compatibility. No rush, just let me know when you have some more data points.

-Jason

[ColtB45]

First, Let me share some good news/egg on my face. I use a mail forwarder and it seems to be responsible for the duplicate emails. Not sure why it duplicates some and not others, but I removed the other 5 addressees and started testing with a different address and the duplicates stopped.

genmon.log is empty less some entries from before I activated the overlay. myserial.log is also empty. mymail.log only has entries about failing to get the incoming folder.

Here are the emails from a manually initiated transfer.

Another fun aside, you're not able to use the web interface to stop the generator during a transfer when the running status is cooling down.

I got it shutdown and transferred back but don't know if that's worth reconsideration if someone needs to stop it right now.

Glad to hear the email issue is resolved.

It looks like the engine status has the following sequence:

00000000 - Off Ready 00020000 - Cranking - 12:09:53 PM 00030000 - Running - 12:10:01 PM 00050000 - Cooling Down - 12:10:08 PM 00030000 - Running - 12:15:49 PM 00090000 - Stopping - 12:17:05 PM 00000000 - Off Read - 12:17:12 PM

Firmware: V1.18 Hardware : V1.06

The next steps as I see it are this:

• Check the display on the controller and see if it matches the above sequence. It is possible that generac has changed the display / status bits with new firmware revisions.
• Compare the 7030 Firmware and Hardware revisions and see if there are differences with the other system installed (register 002a).
• Check the 7030 to see if there is additional hardware connected to the controller (two wire, etc)
• If these do ideas do not yield anything useful we can start comparing register dumps between the generators (i.e. there may be another register that will uniquely identify the differences between them)

Presently, the code that interprets the engine status is the same for all models. The code also has exceptions for four types of controllers (Evolution Air Cooled, Evolution Liquid Cooled, Nexus Air Cooled, Nexus Liquid Cooled). If there are more variants or the code should take into account specific firmware versions we can do that.

Is there a way to retrieve the common model number from the registers? Example: G0070300? I see the serial number with generator: getregvalue=01f4 but that's less helpful.

[jgyates]

Not that I have found. As far as identity, reg "0000" will tell if it is Nexus or Evolution and Air Cooled vs Liquid Cooled. I have tried looking at the serial number format, but I have not been able to see any patterns. According to the formus here: http://zillerstore.com/forums/ the serial number is not formatted in a way that will reveal the model number. Generac has a page that will look up the model from the serial number but I have not been able to figure that out from registers.

[ColtB45]

I have other ones with HW v1.06 working. I have FW up to v1.16 working as well. I suspect a change at this point in FW v1.17, 1.18, or 1.19.

G0065510: HW v1.05 FW v1.10

Works as expected.

I'll keep investigating. It seems premature to make a blind decision based on the limited facts so far.

[jgyates]

I wrote a simple python program to parse some data from register dumps people have submitted. I reached out to one user who has FW V1.18 to see if he can weigh in. From the small data set I have (about 18 register dumps) you are the only person how has a Evo Air Cooled with V1.19

@ColtB45 , Just checking in, any additional data on this issue.

[jgyates]

I am closing this issue due to lack of information. Feel free to reopen if you have anything else to add.
