The Allen-Bradley 150-E51NCD Controller is a smart motor controller that is part of the Bulletin 150-E product line of elevator panel controllers that are designed and manufactured by Allen-Bradley to serve as an upgrade for legacy electromechanical technologies that are commonly used for controlling hydraulic elevator systems. The controller is composed of two parts assembled on a common mounting plate which are a base controller and a fault contactor. As the name implies, the base controller of the Allen-Bradley 150-E51NCD Smart Motor Controller is an electronic device where all the intelligent features are programmed and that provides all the motor control capabilities. The fault contactor is an additional emergency safety measure for elevator control applications and it takes control of the elevator in case of a fault in the electronic system.
The main function of the Allen-Bradley 150-E51NCD Smart Motor Controller is to establish current limits to the elevator’s main motor during the startup, normal operation, and stopping of the elevator by user-configurable acceleration ramps. The Allen-Bradley 150-E51NCD Smart Motor Controller offers several useful diagnostic capabilities, such as overload detection, over-temperature detection, phase reversal detection, open phase load detection, phase imbalance detection, and shorted SCR detection. Some conditions like an overload or an over-temperature situation will cause the controller to fail, and they require using the alternate fault contactor that will signal the fault condition that has occured in the elevator operator panel. Only qualified personnel should be allowed to perform any installation, maintenance, and repair work on the elevator panel. The Allen-Bradley 150-E51NCD Smart Motor Controller should be installed in a protected enclosure to prevent dirt, debris, and water from entering it because it has an open-type construction.
