Swap the CT's and see if the fault moves across to the other compressor

Hi Martin58
Your voltage readings are exceeding the +_5% tolerance
Have you checked all your terminal connections and contacts for wear? Swap over the starter modules and see if comp trip moves over.
Then replace starter modules and check your supply voltage and supply cabling and switch circuit connection.I love the smell of Ammonia in the morning!

Re: trane chiller
the manual states 15% tolerance. the unit brings fault up on controls not trip of breakers
