MY Electrical Issues Continue !!!

I , the guy that gave you this thread http://www.garagejournal.com/forum/showthread.php?p=6018101

still has not had any kind of fix ..

I am contemplating though changing the magnetic Starter to one that uses either a 220v \60hz coil or 208 .. I am getting current about 230v on my lines coming to my house . IS there any recommendation in terms of doing such ??

I currently have the coil wire out on A2 and I manually push the contactor to start then attach the wire for the unit to full up , when its complete I disconnect the wire again, one could only imagine how fun that must be !!

Why start a new thread? All the information pertinent to your problem is in the old thread. I would recommend just making a new post on that thread.

Go to original "Help with Quincy QT7.5 Compressor wiring" thread.

Uggg

3 threads just makes things confusing.

Changing the cpil wont help with the supply issues.

U say the voltage is 230v. But is that with a load or no load?

What is the size of your service?

What size wire?

What is the voltage during startup? (a DVM that has a min max avg function will help)

What is the voltage while comp is running?

its 230 with no load , with running load its about 225 . I'm not certain as to how low it drops when the compressor comes on initially though , hence the reason for the chattering .

my thoughts is , maybe .. if I replace the magnetic starter with this
Eaton XTAE040D00E040 40 Amp, IEC Starter, 208V Coil

which is a 208v coil instead of the 240v 60hz one , maybe that would be a resolution . but I don't want to invest that 200usd until I am certain .

What does your wiring diagram say?

You need to find out how low it goes during startup.

How long does it take to come up to full speed?

one guy recommended that I rebuild the control box to match the current I have on the line ..
but we have never seen it dip below 224 so is basically between 224-227v

the original contactor was set to match the 33.3a on the relay ..

when I manually press the contactor the machine starts an works , if I press it in too soft it pushes back an chatters so its safe assume that maybe a coil that requires a lower volt would work ??

What did you use to measure the startup the voltage?

Need peak/min hold feature on meter.

Need peak/min hold feature on meter.

ill try to and check that when I get home and report back ... hope I can remember how to set the peak minimum on the meter
