Hello everyone!
Chiller Carrier 30GX sometimes have alarm code 113 & 313: "Compressor A1 & B1 Star-Delta start-up failure". 02 Chillers has used 9 years old. They hadn't any privious that alarm. Althought,I replaced new SCPM board, new Contactors, new C.T, new Motor Manager... still happen it. Do anyone can help & give me the solution to solve that problem.
Notes: Chiller is modified to use the Motor Manager for each Compressor.
