Sir Gregory, You will not find in any of Danfoss BD documents covering compressor troubleshooting any reference to compressor protected from refrigerant flow damage do to excessive heat. Item #5 refers to high amperage shutdown do to poor condenser cooling. On water cooled BD compressors only the refrigerant removes compressor heat. You would thank very high compressor oil temperatures and pressures would cause high amperage that would trigger module to stop compressor but it does not when refrigerant return compressor cooling is restricted.
