120/208 and 240/416 are the only "standard" voltages that the -004 comes configured with. So, as long as the 120/208v arrows line up on the reconnection board, the set is already running 120/208 and no changes are necessary to pull single phase 120/208. All that you would do is wire up your...
When configured for 120/208 three phase, the generator will be producing 120v line to neutral, and 208v line to line. You can just wire up the neutral and two of the lines (any two; it doesn't matter) to your single phase house, and it will work fine (in most cases). Since your 240v loads will...
The engine surge has to do with the real load on the set; sounds like it may be having a difficult time keeping up with the load you had placed on it. A sign of wet stacking, a weak injection pump, or low compression. Most of the sets I test are capable of around 150-160% of their rating in...
second load test done! Here are the results:
58A resistive load
Ambient temp: 61 degrees
Frequency droop: 61hz (no load) 59.4hz (full load)
Zero visible smoke
Highest EGT recorded 396 degrees
noticeably less "bark" in the exhaust note
For reference, here were my findings with the engine when...
This looks pretty normal to me...those engines typically smoke a little.
The wet stacking that Harleyd315 mentioned is very common with these sets; I have load tested a few that took several hours under full load to "clean up." I would run it under 100% load for a few hours...I will bet that...
x2 what triple jim said. Engine RPM=frequency. The ONLY thing that changes frequency is a change in engine RPM.
With that being said, I would suspect that you just have sticky linkage. Spray liberally with penetrating oil, cycle it through its full range of motion. It should move very...
1. Not all that uncommon to see bad meters, but I would verify it is bad by attaching a DVOM to the meter to make sure it is receiving a proper input.
2. Good! At least you're sure the set is generating power.
3/4. If you are getting voltage at the output terminals, then the breaker is...
In case anybody is really biting their fingernails...I haven't forgotten about this project! I did get the correct button, and I have re-timed the engine. It is now about 1/4 mark from PC. I get the air purged out of the lines and engine started, but didn't have time to run the load test due...
LOL I just have no reason to make it to the FL panhandle!
I lived in Orlando for a few years...too humid for me!
Enough steak, and I may make a special trip back to gator country.
But honestly, if you really want to lure me somewhere, give me a problem to solve that has confused a few other...
I'm interested to see how this develops! I have automated a couple of MEP's using an off the shelf PLC. However, I have never tried to interface them with a commercially available ATS. The programs I wrote simply made the MEP's startup automatic, and delayed closing of the main breaker for...
Done!
All measurements were taken with a Fluke DVOM. Ambient temp was 48 degrees F.
I slowly added load until I got to 58 amps (about 7kw).
I started at 61 hz, set ended up at about 56.8hz (a little more droop than I am used to seeing, but not completely unreasonable).
Zero visible...
Well, I really like theory. Knowing what should happen is always a good thing.
I also place just as much value on experience! Knowing what ACTUALLY happens often differs from what I expect, because I overlooked some little detail or didn't think about some interaction.
So, I plan to load...
The TM says it is "critical."
For those that have tried to load test and/or operate their sets with a known timing problem, how did your set run? Was your timing too early or too late, and by how much?
I have swapped quite a few IP's on -002's and -003's, but I've always taken the time to...
To test the rest of the generator, I swapped an IP from one of my other running generators onto this one. I didn't have the correct button to get the timing right on, but despite having the timing a few degrees too late it seems to run just fine. No other effects from the water in the...
Thanks for the vote of confidence :tank:
I've actually repaired quite a few of these pumps, and replaced a few more. So I know I'll get it back together...I just hate to spend $$ on an 11 hour MEP with water in its injection system!
Had an hour to pull the pump and disassemble it. I've seen my fair share of these pumps...I certainly don't claim to be an expert, but this is the first actual 9328A model 50 pump I have seen in an -002a or -003a. This is the pump that actually matches up with the diagram in the TM's. All of...
