School called after finding this after being closed for 5 days. Low on refrigerant and a 120 volt defrost timer with 208 volts running thru the clock motor. 3 2 Share this post Link to post Share on other sites
oldredrider 2,547 #5 Posted November 28, 2017 Is that bad? Clock must be running fast... Share this post Link to post Share on other sites
squonk 38,814 #6 Posted November 28, 2017 Clock motor not running at all so no defrost periods. Snow blocks the air flow . Evaporator temp drops due to no heat exchange so already low refrig. temp and pressure drops enough the pressure switch shuts off the compressor. Compressor cycles enough to keep the snow around but product isn't frozen. Kind of like a Nov. or March snowstorm. 1 Share this post Link to post Share on other sites
Sarge 3,462 #7 Posted November 28, 2017 Sounds like when I installed the breaker into the panel in the diesel shop for the oil heater - first time it kicked in that fan sounded like a jet engine . Figured out I locked that 120v breaker right into the wild leg on the 3ph panel - cost a switching board but the fan motor did live for awhile until the bushings gave out from the crazy rpm it ran . Put out heat like mad there for a few minutes , though...lol . Sarge 1 Share this post Link to post Share on other sites

Sarge 3,462 #9 Posted November 29, 2017 I can't even describe how long it took me to read up on the differences and try to understand them - we have 3ph in our area but it's not a "true" 3ph as it doesn't use the additional wiring on the poles . The local ComEd lineman tried explaining how it worked and why it probably wouldn't work well on my 1952 Atlas motor for the old Clausing - don't want to damage that original motor . Instead - I'm choosing to use a VFD and a temperature monitor to make certain I don't overheat it . Learning about single phase VFD convertors and all the associated voodoo with this stuff is about enough to drive a guy nuts - no wonder most just source a whole different single phase drive motor or go the DC route instead - which is another can of worms to say the least . I just hope all the effort pays off - haven't tested anything yet as I still have to finish the Clausing and actually run it for the first time .

953 nut 51,399 #10 Posted November 29, 2017 Years back when I was managing a Hydroponic greenhouse facility the owners decided to add on and include red, yellow and orange Bell peppers in our line. While I was busy overseeing the construction of another 20 acres of green house and an addition to the packing house they threw me a real curve ball. The owners (Europeans) purchased and shipped the packing machine for the peppers. The instruction and maintenance manuals were in Swedish and all of the motors were 50 Cycle 220 Volt units, not at all compatible with the 60 cycle 277/480 three phase "Y" service. Had to muster up a great deal of passiveness before calling to let them know the hurdles we would have to overcome. A few thousand dollars later all was well! Having the manuals translated from Swedish to English was an adventure too. Share this post Link to post Share on other sites
