Trane CVAD 27 270Ton won't start "be2.Momentary power loss"

[cesarf]

Hello everyone!...

Im having trouble restarting a Trane Chiller after a brief power failure... we have two of them... the first one started right after the power came back, but the faulty one still shows "BE2" even after restarting the chiller...

Any suggestions? Master Reset procedure? part Replacement?

Please Help!!! Thanks very much!!!

Hi cesarf
You could first try to power down chiller for about 15 seconds then repower. Is it controlled by a tracer? If so you could try to rest that but it is risky and best reset through software - you may loose both chillers by trying this. You could also call Trane and ask them if there are a couple of simple checks to make before placing a service call for a Trane technician. let us know how you go.

TRANSFORMERS IS ABOUT TO TAKE THE STARTER voltage and converts it to UCM 5VCD THIS AS THE VOLTAGE AS INTREPRETA, they are securely connected CHECK NO distorts SOMETIMES WORKING THE CHILLER current transformers (AMPERJE) NO VOLTAGE TO SEND YOUR MODULE AND If not detected voltage that I see it as temporary loss VOLTAGE
