MS290 starting issue

Oh, are you an electrical engineer? Let me see if I can guess; VFD is variable frequency drive? The first thing that comes to mind with PCB is Printed Circuit Board but I guess it could be something else. Is relay logic used a lot? I would think that everything would be controlled by a PLC today given the low cost of the units. I have the privilege of being turned down twice for a position building control panels from the same company; actually, they never responded to my resume; I sent one in for an advert; two weeks later they posted the job again and I sent my resume in again. At least I tried.

 

What brand was it?

I've bought a lot of vfd's over the years. Lots of AB around here, but squareD, Mitsubishi, and ABB too.

One guy I know actually designs drives for Allen Bradley. Fun stuff.

 

Our 10+ YO Danfoss VFD just died recently, displayed 100% speed, but pump no worky, would not respond to any commands. Cut the power feed off, then powered back up after a while...now the screen is blank other than 1 blinking "cursor"...I declared TOD as the last time I talked to Danfoss they said "you still have one of those antiques!?"

 

The screen not coming up is ususlly a sign of a bad capacitor bank. Screen gets ran by dc power.

Hello, did you get the saw fixed yet?

 

No, I did not touch the saw yesterday; working on a friend's computer that is having starting issues; thinking of seeing if there is a PSU in the parts bin and swapping the PSU out. Also had to do some database work for someone in prep to upgrading an application. Rains last night and today, wish I had done the veggie garden work I had on the list; garden is not doing well, too much rain, too cool. The greens beans only half germinated so I resowed the gaps in the row.

 

OK, got back to the MS290 starting issue; gotta have the beast running. I put the new starter spool in without a lot of problems outside of getting the knot out of the starter rope. However, the new pawls are too snug; they won't slide out when I pull the rope. I hunted around for the old pawl, which I had just a few days ago, but can not find it. I wanted to see how the old pawl fit in the new spool.

So what do I do now? I guess I could order new pawls but they may not fit. I am not very happy at the moment.

 

Are the new parts oem ??

 

Here a service manual for see how the parts go

 

and some photos and videos

 

No, of course not, I can not afford OEM anything.

 

I guess I will do a little machine work to match the new pawls to the new spool; I will gauge the pawls and enlarge the holes to match.

 

This is one place where you might need to make an exemption to your rule or be ready to modify the parts you buy.... sometimes they're just plain wrong.

 

This is now the norm. My friend did automotive repair for a living and he told me that is one of the reasons he quit the business; you order parts, and it does not matter if they are OEM or not, everything is made in China or Hatti or wherever, just not in the US. It is all crap. My friend had to replace a radiator, sent three back and the fourth he just made to fit. Sorry for the rant but I am a bit frustrated.

 

Too late to send anything back so I may as well try to make it do and see what happens; already lost my money.
