PROBLEM TO BE SOLVED: To provide a multiple system control system which improves operation continuity.SOLUTION: The multiple system control system comprises a control panel 2a and a control panel 2b. A voltage used for control is detected by a voltage detector 4 and the control panel 2a receives the voltage detected by the voltage detector 4 via a fuse 5a, performs control on the basis of the received voltage, and detects a voltage loss on the basis of the received voltage. In the case where the voltage loss is detected, the control panel 2a is stopped and the control panel 2b receives the voltage detected by the voltage detector 4 via a fuse 5b, performs control on the basis of the received voltage and detects a voltage loss on the basis of the received voltage. In the case where the voltage loss is detected, the control panel 2b is stopped and in the case where voltage losses are detected by both the control panel 2a and the control panel 2b, the multiple system control system is stopped. |
