[VX-200SI connection example]
Note: For activating the VX-200SI, refer to p. 9-27.
[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
p. 7-15.
Notes
• ThewiringfaultdetectionfunctionwillnotworkontheCTRLINchannelsforwhich"Insulationsetting"has
been performed. (Refer to p. 8-32.)
• 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.
