Compressor Protection
The CoreSense Diagnostics module utilizes proprietary
algorithms to protect the compressor and system from
repeated trips of system pressure controls and the
compressor internal overload. The protection terminal
of the module should be wired in series with the system

the compressor contactor. When the module detects
a series of trips as described below, it will activate a
