Control Mode

This mode provides convenient access to commonly used relay control and test functions. When any of the items
listed in the Control Mode list are selected, control is initiated by pressing the ENTER key. The user is prompted
to confirm the action, again by pressing the ENTER key, before the command is executed.
Control Mode commands are password protected using the Control Password function – see section 6.9.

Real Time Clock

Time and date can be set either via the relay fascia using appropriate commands in the System Config menu, via
the data comms channel(s) or via the optional IRIG-B input. Time and date are maintained while the relay is de-
energised by a back up storage capacitor.
In order to maintain synchronism within a substation, the relay can be synchronised to the nearest second or
minute using the IEC 60870-5-103 protocol, optional IRIG-B input or binary input.
The default date is set at 01/01/2000 deliberately to indicate the date has not yet been set. When editing the
Time, only the hours and minutes can be edited. When the user presses ENTER after editing the seconds are
zeroed and the clock begins running.
