Abstract:

Single networkable fault monitoring system for monitoring electrical parameters on at least one electrical phase on at least one interconnected electric chain hoist for various fault conditions. When at least one fault signal is generated, at least one kill signal is generated in the fault monitoring system, causing generation of at least one kill function in at least one chain hoist motor controller. The generated kill function causes a power disconnection to all connected electric chain hoists and/or the entire network of fault monitoring systems. When a fault has been generated, each individual fault signal outputs fault specific diagnostic data from the fault monitoring system to help an operator identify the fault specific electric chain hoist(s) and the specific fault type(s). This data is intended for the purpose of interfacing with an operator monitoring device, LED indicators, data logger, and/or any other user-defined application or combination thereof.
