Re: Felder Bf6-31 compact. Motor brake gone pop
Hello Imran,
thanks for your kind response. ?I¡¯ll have a look for those components you mention tomorrow. I¡¯m not an electrician, although my brother is and if I can make it easier for him, all the better. I¡¯m guessing a schematic is a wiring diagram ?
Many thanks?

Re: Felder Bf6-31 compact. Motor brake gone pop
Alex,
Looking at the schematic some more, K5 timer relay controls K6 relay which connects the rectifier for braking purposes. So if timing is off, look at K5. Relay K1, normally closed contacts (21/22) also need to be functional for braking to work.
Also, T2 appears to be optional. So you may or may not have it.?

I have a schematic of single phase BF6-31 but your machine should have a schematic that would be best to use.
Both single and 3 phase BF6-31 show use of transformer T2, P1 Rectifier and Relay K6 for braking function. Apparently this is before the current era of using electronics implemented on a circuit board.
Felder usually labels all major parts. If you can located T2 and K6 in your electrical cabinet, we can troubleshoot. I am assuming that you are comfortable carrying out this kind of exercise. If not, an electrician should be able to check these 3 components. The part numbers for these components are in your schematic.
Let me know if you need any further assistance.

Re: Felder dust collection vs cyclone
Hi Chris:

The Oneida is a short cone cyclone so will not separate as well as a longer cone Clearvue which is generally reckoned to separate to 99%. The longer the cone the more separation you get but by definition the
more inefficient it becomes because the inefficiency is what drives the greater separation so the motor and impeller have to be sized accordingly. Bill Pentz has all the information to build a longer cone cyclone but I have never heard of any problems with
the Clearvue though using filters is not used much in Australia, fairly rare in fact (at hobby level) as we vent to atmosphere and I don't know anyone who uses a wide belt being covered in dust.?

Re: Felder dust collection vs cyclone
Hi FOG:
?
I don¡¯t know how many others here have one of the pulsed-air-cleaning RL units. I have a 2016 RL250 which uses blasts of pulsed compressed air to ¡°reverse clean¡± the filters. I run all the usual machines,
and importantly, multiple sanders, including the Felder FS900KF (edge sander) and the Format-4 1102 Finish (wide belt sander).
?
The RL250 has zero issues with maintaining dust extraction of fine dust, in so far as the pulsed air system works. I have used my widebelt extensively over many years.
?
However, there is a bit more context you should know about.
?
- The RL250 and up has an onboard compressed air receiver. This reservoir is needed because the cleaning system requires a VERY significant amount of air.
?
- Early on in my ownership I had lots of trouble with chips packing in amongst the 12 cylindrical filters in the RL250. David Best helped me diagnose the
issue: insufficient volume and pressure of compressed air supply. I now have a 550L receiver pressurised between 100-140PSI, with a 30mm supply to attach to the RL250. The RL250 has a ?¡± filter regulator and now we know why. It needs a very significant air
flow of compressed air to work properly.
?
- Since implementing the larger reservoir and feed, I have not had any more clogging issues. I¡¯d chalk that down to user or implementation error.
?
- Also early on in ownership, I had problems with internal hoses popping off ¨C these are hoses which come from the onboard receiver and distribute compressed
air to the blast nozzles situated directly over each filter. This also led to partial clogging of filters through chip jamming/packing. Felder sent me, free of charge, an in-the-field fix with much heavier hosing and securing clips.
?
- I believe all new RL250 units (and larger) now come with the fix in place. I certainly have had no trouble since then.
?
I hope this helps.

I had similar problem with my Clearvue Cyclone - 16"-18" impeller, 5 hp.
About 18 months ago, I added a Wide Belt Sander to my shop... adding dust collection needs on top of my AD951 and Oscillating Spindle Sander. While I have the K700S slider and
the N4400 bandsaw, neither produces enough dust to stress my system.
Clearvue recommended placing a second cyclone body in-line with first, then exhausting into my Wynn double-cartridge stack. The change has allowed me to stay ahead of clogged cartridges,
with the second cyclone body pulling more debris from the air stream. One of my winter projects is to clean my filter cartridges, and they were significantly less clogged than before. I surmise that there is a physical limit to the amount of dust that one
cyclone can handle within an air-stream.
If you want to pursue this idea further, I can send some photos and installation notes.

Re: Felder dust collection vs cyclone
Jonathan,
Thanks for letting us know this Bindicator product exists.? After googling around, it seems you can get a full kit from Amazon.?
Current price is $560, so it's definitely a luxury product.? It might be on my list for way further down the line.? I'll just have to live with manually checking my bin, lol.

David,
I am currently aiming for the 3.2m slider.
i had the same thought about taking the 2.8 meter, when combined with clamps on both ends it is a bit cumbersome to fit 2.4m sheet?

Re: Felder dust collection vs cyclone
Alex, This roto type bin level indicator works well with dust, hog fuel and planer shavings. They are common around sawmills but have an industrial price tag.??There are probably lots of other suppliers.? Photo eye and capacitance sensors struggle in this application.? Dumb mechanical is hard to outsmart.
Here is a pneumatic pressure differential switch that would connect either side of your filter.? I don't know if the pressure range fits your application but the price is right.???
A pneumatic bin vibrator should be inexpensive.? The common design is a steel ball blown around an eccentric track or raceway.? Be careful with these as they can pack material as easily as unpack.??

Try this, it¡¯s called Moen Flo. My daughter works in the remodeling industry and they install quite a few of these, especially for people that don¡¯t live full time at the property. It detects any unusual amount of water Flo and shuts off your main supply, then notifies you by phone of what is going on.
