Motor protection is provided by PT-100, residual current, over- and undervoltage protection and other functions. Various start, stop and torque adjustment options allow exact adaptations to the respective application. The pump cleaning function, for example, can alternately reverse the pump flow and thus free the pump impeller from contamination. The slow forward and reverse inching operation increases flexibility, e.g. when operating conveyor belts and cranes. A built-in bypass guarantees energy efficiency by reducing heat generation during operation. The display and menu navigation is user-friendly. , EAN: 7320500501481.
