Displaying the Status of the Time Synchronisation Source

The internal clock of the GRE110 can be synchronised with external clocks such as the binary input
signal clock, Modbus or IEC60870-5-103 or SNTP(IEC61850). To display on the LCD whether
these clocks are active (=Act.) or inactive (=Inact.) and which clock the relay is synchronised with,
do the following:
• Select "Status" on the top "MAIN MENU" screen to display the "Status" screen.
• Select "Time sync." to display the status of time synchronisation sources.
