Hi The Chiller Displays High Current On Both Systems Fla% Is Over 115 On System 1 And Over 220% On Sistem 2
Just Run For A Few Seconds And Shows High Current
call an hvac company for service. no diy allowed
in the first check:
1- the water volum in condenser
2- water temp. in condenser
3- refrigerant level position in condenser (it's must be under 40%)
4- check Actuator flow (orifice) work "it's between condenser and evaporator"
if you found all that in normal work call company service.
Aamer This Is A 150 Tons Screw Air Cooled Chiller I've Changed The 3 Control Boards Incluiding Keypad And Eprom. Reprogram It All
And Compressor On Sistem 2 Still Shows Too High %fla I Checked The Compressor And Looks Like It Starts Loaded To Me (slide Valve Stucked)
I'm New Here And Besides That My English Is Not That Good So I Can Explain It All Clearly But I Will Never Give Up.
Sometimes You Have To Play With Difficult Cards But That's What Keeps Me Alive. Thanks A Lot
Sounds like slide valves are stuck. JMHO
To much work with too little time!!!!
The micro may not be set up right for the current. I have found this problem before. You can measure the amps with a meter and scale the micro accordingly barring there is nothing wrong with the compressors
"I'm from Texas, what country are you from?"
Im having the same problem. I have seen many trane screws but this is my first york. It starts at 60 amps then loads to 140 amps with the unload solinoid unplugged so the slide valve must be moving I ordered a unload valve hoping this will fix it. I removed the old valve and it only moves about a
1/16" I am thinking it should move more. If I am missing something please tell
My freind there is a separate password to access the settings of your chiller. Call the nearest York service office to fix your problem.
Number 1 rule DO NOT REMOVE THE EPROM of YCAS chiller the program will reset to defaut.
Great, more secret handshake crap!
