How to remove Out of service Led in MiCOM Px3x

After the reboot of the device, the OUT OF SERVICE LED is ‘on’. In order to switch off the ‘OUT OF SERVICE’ LED please enable the device by changing the value of the corresponding parameter by the procedure described above.

Par/Func/Glob/MAIN
Protection enabled
Yes (=on)

Note: Status ‘on’ of OUT OF SERVICE LED may occur due to different reasons. At least one of
the following 3 parameters are not set as follows:

Output relays may not be blocked:
Par/Func/Glob/OUTP
Outp.rel.block USER
No

Device must be enabled generally as described above:
Par/Func/Glob/MAIN
Protection enabled
Yes (=on)

Trip command(s) may not be blocked:
Par/Func/Glob/MAIN
Trip cmd.block. USER
No

Status ‘on’ of ‘OUT OF SERVICE’ LED may occur as well since the self-monitoring function has detected an internal fault of the device. In that case the ALARM LED is ‘on’ too.
