发明名称 Fail safe monitoring apparatus and method
摘要 An apparatus for detecting and analyzing a fault condition occurring in an engine electrical generator set (21) while providing means for inhibiting the engine electrical generator set (21) upon the occurrence of the fault. The apparatus utilizes a run relay (22) connected in series with single contact fault senders (26) to a reference potential. The single contact fault senders (26) monitor various parameters of the engine electrical generator set (21). When a parameter is exceeded, the single contact fault sender (26) opens, de-energizing run relay (22) thereby inhibiting engine electrical generator set (21). Optical isolators (27) monitor the single contact fault senders (26) and provide information on their status to logic determining means (24) to alert an operator of an exceeded parameter. Also provided is a bypass switch (31) to bypass single contact fault senders (26).
