Compressors With Coresense Diagnostics - Emerson Copeland 4MF-13X Application Manuallines

4.5.2 Compressors with CoreSense Diagnostics

WARNING
Ignition source in a potentially flammable atmosphere! Fire hazard! The
electrical switch of the CoreSense Diagnostics module is not an ignition
source during normal operation in an A2L-refrigerant system but could
become one if not installed properly according to the installation instructions.
CoreSense Diagnostics was the standard protection system for Stream 4M* and 6M* compressors
until December 2019 included.
CoreSense Diagnostics combines oil and motor protection, including the oil differential pressure
protection and the observation of the internal thermistor chain. It provides advanced protection
against faults such as high discharge temperature, locked rotor, single/missing phase, voltage
imbalance and low voltage. The module is capable of communication via Modbus protocol. An
external overload protection is not necessary.
