Abstract
PURPOSE: To prevent an abnormal operation of pump by a system wherein the pump is shut down through a simple circuit comprising an under-current relay, a timer circuit, a counter circuit, etc. when primary current of a motor detected first becomes lower than a set point or pulsative.
CONSTITUTION: A motor is checked for primary current with an undercurrent relay UC, which is actuated for occurrence of undercurrent. If this condition lasts longer than a time set on timer UCT, the coil of a main contactor 88 for motor operation is turned off by a contact UCT-b of the timer UCT. Then, where an input current is pulsative, the undercurrent relay UC repeats ON/OFF operation. The number of times for repetition is counted on an electromagnetic counter 6 and where it exceeds a set number of times, a tripping relay is excited, the main contactor 88 is turned off by a contact UCC-b of a tripping relay UCC to stop the motor 1, thus preventing an abnormal operation.
