4.2.4.4 Displaying the Status of the Time Synchronisation Source
The internal clock of the GRL150 can be synchronised with external clocks such as the binary
input signal clock, RSM (relay setting and monitoring system) clock or IEC60870-5-103. 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 "MENU" screen to display the "Status" screen.
• Select "Time sync." to display the status of time synchronisation sources.

The asterisk on the far left shows that the internal clock is synchronised with the marked source
clock. If the marked source clock is inactive, the internal clock runs locally.
Note: If the Binary input signal has not been detected for one hour or more after the last detection, the
status becomes "inactive".
For details of the setting time synchronisation, see Section 4.2.6.6.
4.2.4.5 Clock Adjustment
To adjust the clock when the internal clock is running locally, do the following:
• Select "Status" on the top "MENU" screen to display the "Status" screen.
• Select "Clock adjust." to display the setting screen.
