4.2 Operation of the User Interface
The user can access such functions as recording, measurement, relay setting and testing with the
LCD display and operation keys.
4.2.1
LCD and LED Displays
Note: The contents of LCD screens depend on the relay model.
Displays during normal operation
When the GRD150 is operating normally, the green "RUN" LED is lit and the LCD is off.
Press the VIEW key when the LCD is off to display the "MIMIC", "Metering view", "Fault
view", "Alarm view" and "Event view" screens in turn. "Fault view", "Alarm view" and "Event
view" screens are displayed only when there is some data. The "Fault view" and "Alarm view"
screens are automatically displayed when a fault event and an alarm event occur and the "TRIP"
and "ALARM" LEDs are lit. The following are the digest screens and can be displayed without
entering the menu screens.
