The MAX31865 has a Fault Detection feature. The RTD wires cannot share a common connection across multiple MAX31865, else the Fault Detection feature will detect these additional connections as a fault condition and halt the conversion process.
It is recommended to connect separate RTD lines to the different MAX31865 or use a mux to make those connections.
