3) lights up. Further, when the switch (1) is placed on the bus bar (5) side, the lighting fixture (3) is turned on by turning the switch (2) on the bus bar (5) side. Conversely, switches (1) and (2) are connected to different busbars (5) and (6), respectively.
), the conduction between both switches (1) and (2) is cut off, and the lighting fixture (3) is not lit and is in an off state. In other words, either switch (1) or switch (2) can be operated to turn on or off the lighting fixture (3).

[Problems to be solved by the invention] In the conventional device, the lighting equipment (3
) was set to turn on and off. In other words, lighting equipment (3)
The lights can only be turned on and off in two places,
Operation at more than three locations was not possible.

The present invention has been made to solve the above problems.
The present invention proposes a drive control device for equipment that can drive and control various devices such as lighting devices even at three or more locations, and can also time-limit the turning on and off of lights.

[Means for Solving the Problems] The equipment control device according to the present invention is provided with a plurality of switch groups, each switch group includes a time-limited drive switch, a continuous drive switch, and a stop switch. The device is configured to drive and control the device by energizing the relay according to the selection.

Not only continuous lighting but also timed lighting is possible.

[Example] The features of the present invention will be mainly described below based on the example shown in FIGS. 1 to 3. FIG. 1 is a diagram showing a circuit configuration when a group of switches are provided at three locations to turn on and off a lighting fixture. In the same figure, (24), (25), (2B
) are a group of switches hung in various places, each of which has a lighting switch (24a) that operates the lighting fixture (3) for a limited time.

) to open the contact (8C) and turn off the lighting fixture (3), as well as the continuous lighting indicator lights (12), (17)
, (22) are turned off.

Also, the series contact (7b) of the timer relay (7) is connected in parallel to the contacts (9a), (14a), and (19a).
, (7c) are contacts (9a), (14a), (
19a) are instantaneous contacts and timer contacts that self-hold a timer relay (7) that counts time upon closure of either one. Furthermore, these contacts (9a), (14a
), (19a), (7b), (7c) and a series contact (13a) connected between the timer relay (7),
(18a).

(23a) is a timer relay (7) when a light-off command is issued.
This is a contact point that cancels the set time. And the contact (
The contact (8d) connected between 13a), (18a), (23a) and the timer relay (7) activates the latch relay (8) when the timed lighting command is changed to a continuous lighting command. The set time of the timer relay (7) is canceled and the light is turned on continuously.

Furthermore, the contact point (7d) of the timer relay (7) closes when any of the switch groups (24), (25), and (2B) is lit for a limited time, and the timed lighting indicator light (10), (
15).

(20) is lit to indicate this. In addition, when the contact (8e) is closed, the switch group (24), (25), (28) is turned on by the continuous lighting indicator light (1).
2), (17).

(22) lights up. Similarly, if the light is off, contacts (7e) and (8e) will close and the off indicator light (2
7).

(28) and (29) are turned on.

Next, the operation of this embodiment will be explained. First, turn on the power supply switch (4) and press the first switch (24a) to operate the auxiliary relay (3). After the contact (9a) closes, the relay (7) starts operating. Contact (7
b) is also closed. When the hand that pressed the switch (24a) is released, the contact (9a) is opened, but the timer relay (7)
) are contacts (7a), (7c), (13a), (18a)
.

Self-holding is performed via (23a) and (8d) and time counting begins. At the same time as the timer relay (7) starts operating, the contact (7a) closes and the lighting fixture (3) closes.
) lights will be on. Next, the timer relay (
When 7) counts up the set time, the timer contact (7C) opens and the timer relay (7) becomes de-energized, opening the contact (7a) and turning off the lighting fixture (3). After being turned on for only the set time in step 7), the light is automatically turned off and automatic light-off is established.

Next, after the timer relay (7) is energized by the switch (24a), if you want to turn off the light before it reaches the set time and automatically turns off, for example, press the third switch (24c) to turn off the light. The relay (13) operates, the contact (13a) is opened, the excitation of the timer relay (7) is cut off, the contact (7a) is opened, and the illumination is turned off.

The light is turned off using the third switch (24c), but even if the third switch (25c) or (28c) is used to turn off the light, the contact (18a) or (23a) will open and the light will turn off. When the timer relay (7) is energized and self-holding is applied, the contact (7d) closes and the time-limited lighting indicator light (10) is installed at each location.

It can be seen that (15) and (20) are lit, indicating that the lamp is lit for a limited time.

Next, if you want the timer relay (7) to turn on the lights continuously before the timer expires, for example, press the second switch (24b) for continuous lighting, and the auxiliary relay (
11) operates, its contact (lla) closes, and the operating coil (8a) of the latch relay (8) is energized, causing the contact (lla) to close.
8c) is closed, the contact (8d) is opened, and the self-holding circuit of the timer relay (7) is cut off and reset, opening the contact (7a). However, the lighting fixture (3) will continue to be lit continuously by the contact (8C). After the contact (8a) is activated, the contact (8C) is closed and the continuous lighting indicator lights (12), (17) are turned on.

(22) is lit, indicating that it is lit continuously. At this time, the contact (7d) is opened and the timed lighting indicator light (10) is turned on.

It can be seen that (15) and (20) are turned off and switched from timed lighting to continuous lighting. Currently, I changed from timed lighting to continuous lighting using the continuous lighting switch (24b).
Even if the other second switch (25b) or (2Eib) is used, the respective contacts (tea) and (21a) will operate and perform exactly the same operation.

Next, when the lighting fixture (3) is turned on for a limited time instead of being turned on continuously, the auxiliary relay (14) is activated by pressing the first switch (25a), and its contact (14a) is closed. Also, the same contact (14b) operates and the latch relay (8
) reset coil operates and contact (8d) closes,
The timer relay (7) is energized, and the contact (7b) operates and self-holds, and even if the switch (25a) is released, the time continues to be counted. The lighting fixture (3) continues to be lit continuously only by changing the closed state from the contact point (8C) to the contact point (7a). Furthermore, a continuous indicator light (
12), (17), (22) to time indicator light (10)
, (15) and (20). So far, we have explained the case of timed lighting rather than continuous lighting, and the case of pressing the first switch (25a), but the other first switch (24a)
a) or (28a), contact (8a) or (19)
a) Furthermore, the operation of contact (9b) or (19b) (7) results in an operation exactly similar to that described above.

Next, when continuous lighting is selected and you want to turn off the light, for example, if you press the third switch (213c), the auxiliary relay (23) will be energized and this contact (23
b) is closed, the reset coil of the latch relay (8) is activated, the contact (8C) is opened, and the lighting fixture (3) is turned off. Also, when the lighting fixture (3) is turned off, the relays (7) and (8) are not operating, so the respective contacts (7e) and (8e) are closed and the off indicator light (27)
, (28), and (29) are lit. Furthermore, when the off indicator lights (27), (28), and (29) are pressed for timed lighting or 1M continuous lighting, the contact (7e) is turned on.
Alternatively, the light goes out because (8e) is opened. Now, I used the third switch (28c) to turn off the light of the lighting fixture (3), but if I use the other third switch (24c) or (25c), the contact (13b) or (18b) will close. After all, the latch relay (8) has to be reset, so the contact (8c)
) is opened and the lighting fixture (3) is turned off.

As described above, all the on/off operations such as timed lighting to off, timed lighting to continuous lighting, continuous lighting to timed lighting, and continuous lighting to extinguishing are possible. The lighting of the indicator light will also change depending on whether it is timed lighting, continuous lighting, or extinguished.

Although the above embodiment has been described using three operation points, the same effect can be obtained by providing a group of n switches and turning on/off the light at n points as shown in FIG. Furthermore, by providing a changeover switch in the timer control circuit and the lamp circuit, it is possible to turn on the lighting equipment after a certain period of time has elapsed. The operation will be explained below with reference to FIG. In the figure, (30) is a circuit changeover interlock switch, and when it is turned to the left, it becomes equivalent to the circuit that automatically turns off the lighting fixture (3) after the timer setting time as shown in the example, and the circuit changeover switch (30) is turned to the right. When the timer contact (31) of the timer relay (7) is activated, the lighting fixture (3) can be replaced with a circuit that automatically turns on after a set time has elapsed, and this can be selected as necessary. . Furthermore, in addition to the above-mentioned selection function, even if there are n switch groups installed at each location, selective lighting from each location is possible as in the explanation of FIG. 1. Also, Fig. 3(a),
By changing the lighting circuit of the lighting fixture (3) as shown in (b), its use can be extended to three-phase loads.

If the power of the lighting equipment shown in Figure 2 increases and the contact capacity of the latch relay or timer relay becomes a problem, it can be controlled using an electromagnetic contactor (32) as shown in Figure 3 (a). . In addition, in the same figure (b), (34) is a switch such as an NFB with three-phase power turned on, (33) is a contact that is turned on and off with the operation of the electromagnetic contactor (32) in the same figure (a), ( 3) indicates three-phase loads such as lighting equipment and electric motors. Therefore, the present invention is not limited to the lighting equipment according to the above-mentioned embodiments, but can be widely applied to drive control of equipment, particularly to start and stop operations.

[Effects of the Invention] As described above, according to the present invention, n switch groups are provided to drive and control devices, and each switch group is equipped with switches for time-limited drive, continuous drive, and drive stop, so that the device cannot be driven at n locations. It is possible to operate the device to stop the device, and to reserve the driving time, so that it is convenient to operate the device, and at the same time, it is possible to obtain a device that can prevent unnecessary driving and is excellent in energy saving.
