chillers paralleling
(OP)
dears,
at our project we have two carrier chillers (carrier model : 30GTN090) THEIR SET UP IS FOR BEING RUN IN PARALLEL, when we run them one chiller a time(single chiller) or two machines in parallel we get alarms(T051, T053 AND T055), I have tried the troubleshooting procedure (attached) from the machine manual, unfortunately couldn't find the reason behind that, your opinion about this problem will be highly appreciated .

1- condenser fans running
2- as i understand from the troubleshooting schedule and what happens in reality, every alarm cod is associated with specific compressor(4 compressors in each chiller)so for example when alarm T051 show up on the screen the compressor No.1 will stop and the chiller continue running with compressors (1+2+3), the chiller stopped completely only when the 4 cods (51-52-53-54) show up on the screen, when we reset the alarms then the chiller will restart automatically.
3- since am new to the project, actually i have been informed that this problem is an old one and since the beginning 4 years back.
