PURPOSE:To prevent the system down, by controlling the load with manual switch when a device at multiplex control line side is in failure, through the provision of the manual switch controlling on/off the remote control relay switched with the output of a terminal controller. CONSTITUTION:To the main operation panel 1 and the suboperation panel 2 located at a remote location, terminal controllers 41-43 and 44 of a given number in the panel main body 3 are connected with multiplex control line, and the controllers 41-44 are individually operated with the operation of the panel 1 or 2 for individual on/off-control of remote control relays 61-69 for load control. The panel main body 3 having the controllers 41-44 is provided with manual switches 71-73 on/off-controlling the remote control relays 61-69 corresponding through the selection of the output of the controllers 41-44. Further, if a failure such as open line is taken place for the multiplex control line, system-down can be prevented by enabling load control with manual switches 71-73. |
