RESET CIRCUIT OF INDICATING FAULT FOR POWER DISRIBUTION PANNEL

摘要

PURPOSE: A reset circuit for displaying the malfunction of a power distribution panel is provided to transmit malfunction displaying signal to an upper-level unit using an optical coupler which turns-on when the malfunction displaying signal is received. CONSTITUTION: A malfunction displaying relay(2a) generates signal for displaying malfunction on the outside of the digital central displaying unit of a power distribution panel. A resetting switch(1a) generates signal for returning to an initial state. A reset-digital outputting switch(1c) transmits digital-reset outputting signal to the outside of the digital central displaying unit. A reset digital outputting contact-switch(1c-1) is serially connected with the malfunction displaying relay and receives digital-reset outputting signal. The power is stopped supplying to the malfunction displaying relay.
