[Table 1]

For example, if the voltmeter 5 displays 0 V regardless of whether the selection switch 4 is selected to go up or down, and the breaker of the distribution board 140 falls in the actual use state, the failure mode is as follows: It can be determined that it is short-circuited, and at least the white line 131 and other lines (black line 132, red line 133) are short-circuited.

Whether the selector switch 4 is selected from the rising side or the falling side, the voltmeter 5 displays 100 V, and in the actual use state, when the switch 110 growls or the shutter member does not operate, It can be determined that the failure mode is short, and it can be seen that the black line 132 and the red line 133 are short-circuited.

In addition, the voltmeter 5 displays 0V regardless of whether the selection switch 4 is selected from the rising side or the falling side.
If the shutter member does not operate at all in the actual use state, the failure mode can be determined to be the disconnection, and at least the white line 13
1 is broken, black line 132 and red line 133 are broken, or white line 131, black line 132 and red line 13

When is selected to the descending side, the voltmeter 5 displays 0V,
When the shutter member rises but does not descend in the actual use state, the failure mode can be determined to be the disconnection, and it can be seen that the red line 133 is disconnected.

On the contrary, when the selection switch 4 is selected to the up side, the voltmeter 5 shows 0V, and when the selection switch 4 is selected to the down side, the voltmeter 5 displays 100V, When the shutter member descends but does not rise in the actual use state, it is possible to determine the failure mode to be the disconnection, and the black line 13
You can see that 2 is broken.

As a result of the failure diagnosis, the cause of the failure is the switch 11
If it can be determined that it is on the 0 side, the switch 110 is replaced, and if it is determined that the cause of the failure is on the cable 130 side, the decorative board is peeled off and the failure location is fixed, or the cable 130 is replaced. To do.

According to this embodiment, the following effects can be obtained.

(1) It is possible to determine whether the switch 110 side has a failure or the in-wall cable 130 side has a failure.
When the 30 side has a failure, it is possible to check which failure mode or which wiring 131, 132, 133 has a failure, and also to confirm whether or not the commercial power supply is turned on. Therefore, when the shutter member does not operate normally after installation work or at the time of regular inspection, useless work such as replacement of the opening / closing device 110 and peeling off of the decorative board can be avoided.

(2) Since fault diagnosis can be performed by a simple operation, even a person unfamiliar with the tester or a person with little electrical knowledge can perform accurate fault diagnosis quickly and easily.
