PURPOSE:To improve the working efficiency of maintenance, by checking a controller to be monitored leaving it in an operating state, in case of checking a control output signal. CONSTITUTION:By switching a switch 13 to a terminal (e) side, the control output signal inputted to an input terminal (a) is impressed on a relay 14. When the relay 14 is turned on, a relay 15 is worked, and when the relay 14 is turned off, an ordinary remote control operation is performed because the relay 15 is not worked. By switching the switch 13 to a terminal (f) side, an inputted control output signal is impressed on the relay 14 through a Zener diode, therefore, the voltage of the control output signal goes to around 5V, and the relay 15 is not worked regardless the ON or OFF of the relay 14. Consequently, it is possible to check the control output signal by measuring the voltage Vo of signal using a tester, etc. |
