6 to operate control relay 5.6. Also,
The test request signal is simultaneously applied to the test relay 12 to operate the relay 12.

号出力回路の動作が正常であることを知らせる。The operation of the test relay 12 causes the contact 13 to break, the control signal line 3.4 is cleared of air regardless of the state of the contact 9.10, and the operation of the control relay 5.6 causes the contact 9, IO to open. do. By metering the relay contact 9゜IO, the power supply voltage terminal V is connected to the operation confirmation signal line 14.1.
5 (on the open contact side), power is supplied to the information processing section to notify that the operation of the control signal output circuit is normal.
