Description
AUTOMATIC SYSTEM FOR D-O-L STARTER FOR WATER PUMP MOTORS FULLY AUTOMATIC FUNCTIONS: This meticulously designed system triggers Direct-on-Line starters ON switch which energizes pump motor when water level in overhead tank goes below the pre-set point, and switches off the starter immediately when overhead tank fully fills up. The controller is so designed that it will trigger the ON switch of D-O-L starter with auto-resettable 3 seconds timer. Controller will separate itself from the said starters ON switch after 3 seconds leaving it to work independently through starters thermal relay mechanism which is designed and calibrated to provide effective protection against overload or short circuit. This way the system, not only saves water, manpower & electric energy but also enhances the life of pump motor. The system is also compatible with single phase submersible (borewell) motor starters which are having one switch in “Start Button”.
