Abstract

PURPOSE: To enable the detection of trouble extending over a wide range and protection by opening a unit consisting of a motor group and a controller according to a condition that the main currents of the unit reach a predetermined value or do not exceed and allowable value.
CONSTITUTION: When a closing command L is given, a condition setter LL closes breakers L1, L2 when every kind of conditions are satisfied. When the main currents do not reach prescribed currents and a current relay CR is not operated even when a fixed time passes after operation is started, a time limit relay TD is worked, a unit non-operating relay AR is operated, and a display lamp P1 is lit. On the othr hand, when overcurrents flow through a circuit of motors M1, M2 during travelling, an overload relay OLR is worked, and a display lamp P2 is lit. When a switch S1 is operated under such a condition, a unit opening relay UNR is worked, and the breakers L1, L2 are opened.
