Beschreibung
Zusammenfassung:	A method of monitoring a backup battery for a magnetic bearing centrifugal compressor. The method includes: establishing threshold voltage values applicable to the battery backup battery level; monitoring the actual voltage of the battery backup; comparing the actual voltage of the battery backup to the threshold voltage; initiating a soft shutdown of the magnetic bearing centrifugal compressor if the magnetic bearing centrifugal compressor is operating and the actual voltage is below the threshold voltage for a defined period of time; preventing the magnetic bearing centrifugal compressor from starting if the magnetic bearing centrifugal compressor is not operating and the actual voltage is below the threshold voltage; or allowing the magnetic bearing centrifugal compressor to continue operation or begin operation if the actual voltage is greater than the threshold voltage.
