The ABUS load indicator system LIS-SE is a load measurement and evaluation system designed for hoists and crane installations. The LIS-SE is intended especially for use in hoist control systems. Its main function is overload protection through evaluation of the current and voltage of the hoist motor. An optional load population recorder can be used to log the actual operating mode of the hoist. The LIS-SE is intended especially for use in pole-switchable three-phase motors.
