Abstract

To address the issue of different industrial equipment requiring different starters to adapt to various control systems and command settings, this invention discloses a flexible starter adaptable to a variety of high-power devices. This flexible starter comprises a first relay coil, a second multi-function relay coil, and a third relay coil connected in parallel. A jumper that can be selectively closed or opened is provided between the first relay coil and the second multi-function relay coil. The first relay coil controls a normally open contact of the first relay that can be shorted, the second multi-function relay coil controls a normally open contact of the second relay, and the third relay coil can selectively control a normally closed or normally open contact of the third relay.
