In FIG. 2, the cable wiring is checked by first transmitting a pulse signal having a pulse rate a from the pulse transmitter A17 in the main body 10, and inputting the pulse signal from the pulse signal output connector 12 (pin 1). The signal is detected by the pulse detector A21 via the connector 13 (Pin 1).

[0014] The pulse detector A21 is a pulse generator A
The information that the signal from 17 has been detected is transmitted to the microcomputer (control device) 30 and processed, and displayed on the display 40 as "output connector 1-input connector 1" as shown in FIG.

The above operation is performed by the pulse generator D of the main body 10.
18, sequentially with the pulse transmitter C19, and the pulse transmitter D
A pulse signal having a pulse rate d is transmitted from 20 and is detected by the pulse detector D24 from the pulse signal output side connector 12 (4th pin) via the pulse signal input side connector 13 (4th pin), and is then detected by the microcomputer (control device). 3
The process is repeated until the transmission process is performed to 0 and the wiring is displayed on the display 40.

When the cable wiring check is completed, a completion message is displayed on the display 40. FIG. 5 is a screen showing the wiring display on the display after the completion of the cable wiring check. Here, if any of the wires in the four cores is disconnected, a disconnection indication is displayed on the display 40, and the pin number of the disconnected output side is displayed.
