[VX-200SI connection example]
Note:
for activating the VX-200SI, refer to
[Control line surveillance]
function for detecting a wiring fault in the cable connected to the external control output device can be set to
the control input terminals of the VX-200SI.
connect the resistors to the cable of which fault is to be detected as shown above.
for the method of setting the fault detection function to the control input terminals, refer to
.
Notes
• The wiring fault detection function will not work on the CTRL IN channels for which "Insulation setting" has
been performed. (refer to
• Be sure to connect the resistors as shown in the diagram above.
If no resistors are connected or resistors other than specified are used, the fault detection function will not
work correctly.
• To assure stable operation of this wiring fault detection, it is recommended to use a shielded twisted pair
cable of 10 m or less.
• Be sure to connect each shield wire to the functional ground terminal of each device.
