Larry has uploaded new versions of his 3-phase wiring diagram and notes in
HTML/GIF format to the Vault.
(by the way, thanks to Felder USA for also uploading an HTML version of the
Special of the Month! If anyone had troubles getting it to load before,
check it out now.)
Larry's system turns on the 3-phase dust collector automatically whenever
any of the machines are in use.
Does this Auto-Switch relay have any sort of timers built in so it doesn't
switch on the dust collector for a few seconds (to avoid two motors loads
starting simultaneously), and another delay to run for a number of seconds
after the machine is shut down to clear the pipes/hoses? If not, could this
be added with additional time-delay relays?
Also, I have an old article from Fine Woodworking that shows how to build
automatic blast gates. I wonder if that could be integrated with this design
as well. I'm going to have to dig up that article...
