6.1 Monitoring
6.1.1 Indications
The operation of the protection relay can be monitored via three different indications
on the LHMI.
• Three indicator LEDs with fixed functionality: Ready, Start and Trip
• 11 programmable LEDs
• Information on the display
6.1.1.1 Monitoring indication messages
Indication messages and tripping data are shown in a dialog box. Only one dialog box
can be shown at a time, therefore the relay has internal priority for indication messages
and tripping data. Internal fault and warning messages have always higher priority
than start or trip information. Trip information has always higher priority than start
information.
1. Read the indication message in the dialog box.
The message can indicate the starting or tripping of protection functions or an
internal fault in the device.
2.
Press
to close the indication message without clearing it or press to
activate the Clear view and to clear messages.
