Increases the availability of conveyor systems with Eaton's PKE motor-protective circuit-breaker and SmartWire-DT

As one of the leading manufacturers of components and systems for electrical engineering and automation, Eatons Electrical Sector solves heavy load issues in the motor control of conveyor systems with a combination of the PKE motor-protective circuit-breaker and the SmartWire-DT communication system. The result is comprehensive indication functions and extended drive monitoring, even under tough conditions. Unnecessary outages can be prevented.

The overriding advantage of the PKE motor-protective circuit-breaker compared with conventional solutions lies in the expanded drive monitoring. The diagnostic, status or overload messages show the actual flow of current and display the status of the overload trip device. The actual motor current can be continuously displayed and analyzed via Eaton’s “SmartWire-DT”, the cost-optimized communication system for switchgear, without additional components. Depending on the drive application, the following operating states can be differentiated: motor switched off, motor underload, motor no-load, motor operation, motor overload and motor fault. The separate load limits and the time response behavior can be individually programmed and adapted to all drive tasks. Emerging faults can be identified in good time thanks to the transmission of motor current and overload status. This enables the system operator to intervene in the production process before an undesirable interruption occurs. Of particular interest in this case is the option to operate the PKE as a motor protection relay. The motor-protective circuit-breaker is then not triggered in the event of overload; only the associated contactor is disconnected. Once the overload situation is rectified, the motor can be switched on again via the control unit without the maintenance personnel having to first reset the protection switch

Frozen elevating conveyors and typical belt conveyor scenarios when transporting coarse bulk material can only be insufficiently tracked in conventional drive control systems, as individual motors or belts at standstill are only indirectly interpreted via the switching states of the motor-protective circuit-breaker and power contactor. A hardware solution such as a speed sensor, load-shedding relay etc. is additionally required for a specific, reliable response. In the event of overload, the drive is immediately disconnected when the set current value is exceeded and a fault is signaled to protect the motor from being destroyed. This results in unscheduled, time-consuming and costly downtimes because conventional analog I/O technology cannot image the current motor current as continuously and in such detail as the Eaton solution and therefore shuts down more often than necessary.

Caption: The use of the PKE motor-protective circuit-breaker in connection with SmartWire DT enables central monitoring of all the drive motors of the conveyor belts and considerably increases the system’s availability. icación consume hasta un 65% menos de recursos y, al utilizar únicamente el material requerido, se reducen las emisiones de gases de efecto invernadero hasta un 30%. Además, permite, de forma generalizada, fabricar componentes con una vida útil más larga.

Siemens tiene la intención de ayudar a impulsar este rápido crecimiento mediante el desarrollo de productos de próxima generación, servicios de ingeniería y soluciones digitales. La compañía tiene planes para hacer que la producción de FA sea aún más flexible.

En un futuro cercano, las impresoras 3D estarán ubicadas en cada uno de los centros de servicios de Siemens con el fin de imprimir recambios y piezas a nivel local acortando exponencialmente los tiempos, e incluso se podrá producir una pieza de repuesto antes de que se origine un deterioro.
