The %Load function on my system is measuring the voltage/current that each winding pair is contributing to the load. It's actually measuring the voltage at the 3 different phase load inputs to K8 the overload relay from the burden resistors. When in 120 or 120/240 mode the %Load readings from...

It's screwed into the back of the engine block down low. Operation is switch is OPEN at cold or normal operating temp. Switch is CLOSED if there is a high temp issue.

I have a good, tested, used one available if it turns out your Fault Monitor failed. My money is on a bad OP switch. Easy test to determine if it's the OP switch assuming you have batteries in the set or you are slave jumping it. Put S1 in the RUN position. Do not start it. The Low OP light...

Yes, there is an oil pressure switch. They fail with some frequency on the 831's. The -13 TM has a test procedure for it. It's screwed into the block on the left down low. Operation is switch is closed with no oil pressure and open with oil pressure. It might be the Fault Monitor itself...

Link to the Technical Manuals TMS's) for your set -----> MEP-005A TM's Don't create multiple threads for the same question. The Moderators get cranky when you do. It also makes it harder for us to help you when there are multiple threads.

Fault 1452 indicates that the DCS did not get the contactor closed signal from the contactor after you pressed the contactor open/close button. Possibly your contactor has failed or there is a wiring problem between the DCS and the contactor. The -24 TM has the troubleshooting steps for this issue.

Those wire clips are part of the stud assembly. They don't have an individual PN. Only was to get them would be from someone parting out an 802,803 and willing sell just the clips. One could probably fashion something out of stiff wire to serve the same purpose. That or double nut the terminals.

You will NOT have 24 volts there unless the engine is running. The Oil Pressure relay K20 has to close to provide 24 volts to that circuit.

I was also able to get the 44 parameters at 115200 without the preliminary handshaking. :) That makes the code simpler!

Nope, the internet was just in its infancy when I graduated. Back then it was only used for connecting a few scientific facility together. Voice recognition was just in its beginnings too. It took an 18" rack full of stuff to understand a dozen words. We had to train it by speaking the same...

I agree the code can be more concise. It was the first pass at decoding the data to get it to work. I was simply evolving the code to get it to work. I was going for "function over form" initially. Now that it's working it could certainly be made more concise. Back when I started doing some...

Your "Z" issue may be due to a noise or signal level issue on the 485 data. I ran into an issue with the 485 levels being too low causing issues. Once the levels were corrected data became consistant. Is your Pyserial interface using a hadware UART or is it a bit basher serial port emulator?

For example you read back \x93\x02\x00\x00\x91' The 93 is just a transmission header. Ignore it. The 02 indicates that the next 2 bytes are the data. 00 & 00 are the data. The 91 is the checksum. Here is the code I use to decode the data coming back from the DCS. The DCS response bytes are...

Interesting. I'll have to try 115200 without handshaking the next time I fiddle with that project. Which math? Decoding the values coming back from the DCS??

Interesting. I tried to just send the 44 requests quite a while back and got no responses. What baud rate are you using?

What I found was the handshake to establish communications thru the remote port seems to use/need minimum delays between sending each of the handshake messages to the DCS. The delays are what I measured using a PC with the Remote Monitor software doing the handshaking and an ESP32 sniffing the...

I find the 1030 quieter than my 802A. Not a HUGE difference, but definitely noticeable. The 3rd cylinder in the 1030 makes the engine purr compared to the 2 cyl paint shaker 802A.

You beat me to it :LOL:

A potential replacement candidate for the 8906K4519 S5 Interrupter switch is a Honeywell 2TL1-70. They are about $62 now. They used to be $35 2 years ago.... The contact operation of the 2TL1-70 is slightly different than the 8906K4519 so some wires would go to different terminals. I haven't...

Have you performed the troubleshooting steps in the -24 TM? If so, what were the results?
