Generates and holds a control output for turning on the electromagnetic contactor Mg based on the control data. When the operation switch S ₂ is pressed, the CPU 31 gives control data for turning off the power load M ₁ to the control input / output unit 4, and the control input / output unit 4 turns off the control output based on the control data to cause electromagnetic contact. Bowl M
g is turned off, and the off state of the control output is held until the next control data for turning on is given.

In the automatic mode, the CPU 31 supplies control data to the control input / output section 4 based on the operation data from the external input device 5 or the network to operate / stop the power load M. Whether it is received from the external input device 5 or the network can be set by a setting operation described later. In the off mode, the operation is stopped and the control output from the control input / output unit 4 is turned off.

Under the control of the CPU 31, the present operation current value, individual alarm data, peak current value, cumulative number of operation / stops, and integration are displayed on the numerical display section 34A and the unit display section 34B of the display operation unit 3A. The operating time can be monitored,
This monitor can be changed by operating the display changeover switch SWb, and the settings such as inrush current avoidance time, overload warning level, light load warning level, start delay time in case of power failure, and external control method can be set. Settings can be made by operating SWa and the display changeover switch SWb.

Return to the current value display. If the display changeover switch SWb is not operated during the display duration of the call display item, the normal display state is restored. If there is no alarm to be notified in the individual alarm data, this display is skipped. It is also designed to jump to display items.

Here, the individual alarm data includes the trip information of the breaker Br, the overload warning, the light load alarm, the network transmission failure, the abnormality of the CPU 31, the abnormality of the EEPROM 37, the reset of the control input / output unit 4, and the display operation unit itself. Reset etc. are displayed with a combination code of numbers and alphabets. The number of times of operation / stop is counted by the CPU 31, and the integrated operation time is also measured by the CPU 31 and stored in the built-in RAM.

Data setting is possible when the operation mode is the OFF mode. When the setting changeover switch SWa is operated, the display contents of the numeral display section 37A is switched according to the setting item, and when this setting item is displayed. For items that can be set by the user, the display changeover switch S
When the operation of Wb is performed, the displayed numerical value is switched. If the setting changeover switch SWa is operated at the time of displaying a predetermined numerical value, the displayed numerical value is set as the set numerical value, and the EEP is controlled under the control of the CPU 31.
It will be written in the ROM 37. Here, when the network is set as the external control method, the operation data of the network is valid in the above-described automatic mode, and conversely, when the external input is set, the external input device 5 is used.
The operation data of is valid.

Of course, the data written in the EEPROM 37 also includes a unique address on the network. Note that these settings and monitoring may be performed using the setting device 50 shown in FIG. 12 that uses an optical wireless signal.
