Fault indicator (yellow/red LED)
Fault indicator (yellow/red LED)
If the LED is lit red, a SCALANCE X-200RNA has detected an error/fault.
At the same time, the signaling contact opens assuming that the response of the signaling
contact has not been configured differently.
The LED signals that the SCALANCE X-200RNA can adopt the following statuses:
Device type SCALANCE
LED lit red
LED lit yellow
LED not lit
X204RNA
