8.2.3 Display
The display is a graphic display with following menu pages:
8.2.3.1 Default page
Default page shows the status of the protection devices and the status of two monitored lines and
eventually of the generator. Status is shown as a graphic picture, where graphic LEDs and a specifi c
line status code indicates the status of LN1 and LN2. When the LED is OFF, there is an anomaly in the
line and the status code for the line is 1. When the LED is ON, there is voltage in the line and the status
code is missing. In the case of an anomaly, the LED is OFF and the status code indicates what is at fault.
Below the line status code the measured values of voltage and frequency are shown. Status codes are
defi ned in the table below:

When the generator is started, the letter G and the “arrow up” symbol on the right side of line 2 (LN2)
status are in the default page. When the generator is stopped, the letter G and the “arrow down” symbol
on the right side of line 2 (LN2) status are in the default page. When the generator is not used, there is no
sign in the default page (see the page 32, Generator Usage).
