When the selection has been completed continue to press the [F] key until the
confirmation display appears and confirm the selection.
Now step down the menu to cell [0004 Description] and enter a suitable name for the
configuration; a maximum of sixteen characters are available.
Step down one cell [0005 Plant Ref.], where a suitable reference can be entered for the
plant that the relay is to protect. If the configuration is for a relay that is to be applied to
one particular circuit, then the reference by which the circuit is known can be entered at
this time; a maximum of sixteen characters are available.
Now move down the SYSTEM DATA column to cell [0009 Freq] and set the frequency to
50Hz or 60Hz as appropriate. This is an important setting because it will be the default
frequency used by the analogue/digital converter when appropriate signals are not
available for frequency tracking.
If the address of the relay on the serial communication bus is known then it can be
entered at this time. This cell is password protected on the series 2 relays.
This concludes the settings that can be entered in this menu column at this time.
