Abstract

PURPOSE: To display the faulty points for the first failure point and on and after the second failure point when the occurrence of a failure is detected, and to detect and display the restoration of the failure.
CONSTITUTION: If the first failure is taken place at the station such as power station and the failure contact point X1 is closed, the output pulse signal from the pulse circuit PA is given to the alarm circuit B to produce alarm. Further, the lamp R1 starts the first flicker with the operation of the thyristor S1 and the said S1 is held. The alarm circuit B is restored and the alarm is stopped by depressing the alarm reset push button switch AR. The restoration of the first failure is informed with the second flicker display of the lamp W1 and the production of alarm. Next, if X1 is operative with the failure on and after the second failure point, B is operated and alarm is caused. Further, the display of the lamp W1 by the second flicker signal informs the state. The restoration is informed with a given operation succeeded to it.
