Abstract

PURPOSE:To prevent surely accidents due to careless operations of a suboperator with simple constitution, by providing a manual changeover switch which makes the control operation from the suboperator effective or ineffective. CONSTITUTION:By program keys 4, not only a schedule program for the time schedule of every load 3 to be controlled is set but also a program for the correspondence relation between every load 3 and wall switches 2 by which respective loads should be remote-controlled is set. When a manual/automatic changeover switch 5 is set to the manual side, every load 3 is controlled to be turned on and off in accordance with the schedule program. At this time, conditions of switches 2 are monitored by a main operation panel 1, and the control due to the program is continued when the switch 2 is turned on, and all switches subordinated to the switch 2 are turned off forcibly when the switch 2 is turned off. Meanwhile, when the switch 5 is set to the automatic side, states of switches 2 are ignored, and loads 3 are controlled by the program.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention allows a large number of loads to be individually controlled to be turned on and off using a main operation panel (set schedule program) and operation input from a sub-operator. This invention relates to a load control device.

Conventionally, as shown in Fig. 4131, each controlled load (1) of 1hn is turned on and off by the schedule U0 program for 9 time schedules set on the main operation panel {1)/) program middle + 4). While the control is being carried out, the control status of each controlled load Ill in response to the operation of the %1 switch (! ) etc. are constantly monitored on the main operation panel (1), and when this is operated, all controlled loads (3) are forcibly turned off based on the above preset program 4, or individual corresponding controlled loads are A load of 4 ml was controlled by switching between on and off combinations.

However, in such a conventional example, a one-switch(!) intermediate operation panel or other sub-operator is always in operation,
Depending on where these are installed, there is a risk that if kept, the auxiliary external controller for forced all-off operations may be operated by mistake in stores, factories, etc., causing an unexpected situation.

The present invention has been provided in view of the above-mentioned points, and it is possible to freely set the time period in which the controlled load can be controlled by the sub-controller, and the sub-controller, which is normally only used at night or on holidays, can be used during work. It is an object of the present invention to provide a food cost control device that prevents unforeseen situations from occurring due to manual operation.

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 2 shows one eleventh embodiment of the present invention, as described above! In the example shown in Fig. 81, a manual automatic changeover switch (Il) is provided to set whether the control from the remote control is effective or the acupuncture effect.In the illustrated example, the main operation panel (1) and each controlled load (s)... are connected by one-to-one back wiring, but a multiplex transmission method using a dedicated line is used to connect the main operation panel + 1) to each controlled load (3). Therefore, in the embodiment of FIG.
sets the schedule schedule for each controlled load (according to the 11 hour schedule), and also sets the correspondence program for which wall switch is to be remotely controlled for each controlled load T8. It is something to do. That is, depending on the settings of the schedule program (OI), for example, the load l will be set from 8 o'clock to 9 o'clock.

The fk data is set to turn on λ4, turn off load &5, and turn on all loads LLIL4S from 9 o'clock to 10 o'clock. Dark is set such that the load LL8 corresponds to the wall switch 2 and the load 45 corresponds to the wall switch 2. Thus, when the sliding automatic changeover switch (11) is set to the manual side, the same operation as that of the conventional example described above is performed, and each controlled load +11 is used to operate the wall switch (2), etc. Normally, each controlled load (3) is controlled on and off according to the schedule program mentioned above, but at this time, the main operation panel (1)
The system constantly monitors the status of the wall switch (phantom, etc.), and when the wall switch is on, it continues to be controlled by the scheduler, and when the wall switch is off, the wall switch (2) K is All dependent controlled loads (3),
The scheduler will be ignored and turned off forcibly. On the other hand, when the manual automatic changeover switch (-) is set to the automatic side, the status of the - switch (2) is all set to m*,
Each controlled load (3) is subject to control only according to the schedule program (OI).

FIG. 3 shows another embodiment of the present invention, in which the main operation panel 1111
In 1), in addition to the above-mentioned schedule program and correspondence relationship setting in program 14), from the main operation panel (1) K, the time period for monitoring each wall switch is set in advance as a program. Thus, the control (2) corresponding to the switching operation of the manual automatic changeover switch (6) in the embodiment shown in FIG. In the embodiment shown in FIG. 3, it is possible to set in advance the time when the remote-controlled wall switch, sochi, etc. will be effective, as a time schedule, and also the time setting. This makes it easy to change a plurality of control loads remotely controlled by the same wall switch (2).

As described above, the present invention provides effective control operations from the auxiliary controller,
Since it is equipped with a manual/automatic changeover switch to set the disable, it is easy to configure and enable/disable the second actuator by manually or automatically switching the manual/automatic changeover switch on the main operation panel side. And even though it is easy to operate, it ensures that accidents due to the operation of unnecessary sub-controllers are prevented.
! It has the effect of stopping
