A device monitoring and recording apparatus comprises sensing means, computing means, memory storage means and power supply means. The sensing means are operative for sensing device operating parameters and generating data signals corresponding thereto. The computing means process the sensed data signals and the memory storage means stores the data signals from the computing means. The power supply means provides power to the device as well as the computing means and memory storage means and comprises means for sensing a power fault condition and for generating a fault status signal in response thereto, means for feeding the fault status signal to the computing means and means for shutting down the computing means as well as the device upon receipt of a shut-down command from the computing means. The computing means initiates a data protect routine prior to generating the shut-down command.
