Monitoring

Indications

The operation of the protection relay can be monitored via three different indications on
the LHMI.
• Three indicator LEDs with fixed functionality: Normal, Pickup and Trip
• 11 programmable LEDs
• Information on the display

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 pickup or tripping of protection functions or an internal
fault in the device.
2.
Press to close the indication message without clearing it or press
the Clear view and to clear messages.
