In addition to taking in the control data of s, the monitor data signal is returned as a current mode signal (a signal transmitted by short-circuiting the signal lines 4 through an appropriate low impedance) in synchronization with the return signal WT of the transmission signal Vs. It is supposed to.

The central control unit 1 includes a dummy signal transmitting means for constantly transmitting a dummy transmission signal in which the mode data signal MD is set to a dummy mode, one of the monitoring terminal 2 or the wireless relay terminal 7, and an external terminal. When an interrupt signal Vi as shown in FIG. 20B returned from the interface terminal 8 and the selector switch terminal 9 is received, the interrupt generating terminals 2, 7 to 9 are detected and the terminal 2, Interrupt processing means for accessing 7 to 9 and returning monitoring data is provided.

The wireless relay terminal 7 is a terminal for relaying data of an optical wireless system composed of an optical wireless transmitter X, an optical wireless receiver Y and a wireless signal line 4a. The received optical signal is received by the optical wireless receiver Y, the received data is received via the wireless signal line 4a, and this data is transferred to the central control device 1.

(Latching relay that can be turned on and off also by a hand switch) 5 is controlled.

[0009]

When controlling a lighting load in such a control system, a plurality of lighting loads are divided into groups, and a group control is performed for each group and a lighting load is controlled only for a certain level of a building. Floor pattern control, and total pattern control when controlling the lighting load of the whole building. Here, the control load target range increases in the order of group control, floor pattern control, and total pattern control.

The pattern control includes batch ON,
There are collective off, temporary lighting, thinning-out lighting, partial off such as turning off near windows, dimming lighting, and the like. Conventionally, when pattern setting and group setting are performed, a group setting switch, floor pattern setting switch, and total pattern setting switch are required separately from the selector switch terminal device. After the operation is completed, the system must be returned to the normal state (load control state) and set again by the group setting switch, which has a problem that the setting time becomes long.

The present invention has been made in view of the above points, and has as its object to shorten the set time even when the load range to be controlled is changed.

[0014]

[Operation] By using one setting switch unit, the control load can be set for each of the large, medium and small control load target ranges, and the setting time can be reduced even when the control target load range is changed. I try to plan. In addition, the openable door that covers the operation surface of the setting switch unit is screwed and this screw is hidden with a small door, so that the load control range can not be easily controlled by children's mischief etc. I have.

Furthermore, by writing the address of the setting switch unit in the EEPROM in advance in the manufacturing process,
This eliminates the need to write data later by the address setting device, thereby simplifying the circuit configuration. In addition, the shaft supporting portion for supporting the shaft formed on the cover of the setting switch unit is formed in a substantially U-shaped cross section, so that the door can be easily opened even if an excessive force is applied to the door with the door opened. To prevent the door from being damaged.
