Abstract
PURPOSE: To enable to confirm the operation of the mutual connection cables and the reception circuit with a simple circuit constitution, by delivering the inspection signal every plurality points or system from the reception side to the signal source at the field.
CONSTITUTION: At normal monitor condition, since S1,S8 are turned off and S2 is ON, if the signal contact 1-1 is turned on, for example, the relay 3-1 is operated, turning the contact 4-1 on and information is inputted to the information processor 10. Next, at the inspection of the reception circuits of N, S1 is turned on and s2 is OFF, operating the auxiliary relay 8 and since the voltage of the line P is applied to the bus T, the reception auxiliary relays 3-1 to 3-N are activated through the diodes 2-1 to 2-N, turning on the contacts 4-1 to 4-N. However, no input signal is given to the unit 10. If the cables and the reception auxiliary relays from the signal contacts 1-1 to 1-N to the reception auxiliary relays 3-1 to 3-N are all normal, it can be noticed that the relay 7 is operated. On failure, since the contact corresponding to the line is not turned on, the display unit 9 is not illuminated and the condition can be known
