Abstract

A monitor and control system for a ship's electrical power supply of the type having a standby generator. The system includes a variety of threshold detector sensing means responsive to various conditions relating to the operation of the generator. Upon the occurrence of a malfunction, the threshold detectors provide digital signals to an alarm logic circuit which actuates an audible alarm and enables a gating means so as to pass a pulse train to a lighting circuit and thereby provide a flashing visual alarm. The alarm logic circuit also contains acknowledge means operable by a member of the sbip's crew. Operation of the acknowledge means switches a flip-flop so as to silence the audible alarm and maintain the visual alarm in a constantly illuminated condition. Correction of a malfunction returns the corresponding threshold detector to its normal condition, resets the alarm logic circuit and extinguishes the visual alarm. The system further contains an automatic transfer logic circuit which responds to the threshold detectors so as to remove the operating generator from the line when a malfunction occurs, determines if the standby generator is operative, and connects the standby generator across the line when its voltage and frequency have reached acceptable levels.
