Anybody recognize this type of setup? This cabinet houses starters for two 30 HP 480 volt Exhaust Fans on top of the Annex at a Grain Elevator. (The third smaller starter is for a Grain Drag) There is an identical cabinet behind this one for two more fans.
I'm troubleshooting these two fans right now. The control circuit is doing Goofy things. Fan #4: The stop button will shut it off until I release (the button) and it will kick it right back on. Fan #3: was doing the same thing a couple of months ago but now won't turn on at all. Sometimes, when I shut the control circuit off, and turn it back on, Fan #4 will go back to normal operation again...not everytime though. Fan #3 still doesn't operate.
I'm not familiar enough with this 'pushing 40 years old' setup to know really what to do. Any thoughts?
Thank you!
