The relay is available with two optional displays, a
large one and a small one. The large display is
suited for relay installations where the front panel
user interface is frequently used and a single line
diagram is required. The small display is suited for
remotely controlled substations where the relay is
only occasionally accessed locally via the front
panel user interface.
The LCD display offers front-panel user interface
functionality with menu navigation and menu
views. The display also offers increased front-panel
usability with less menu scrolling and improved in-
formation overview. In addition, the large display
includes a user-configurable single line diagram
(SLD) with position indication for the associated
primary equipment. Depending on the chosen stan-
dard configuration, the relay displays the related
measuring values, apart from the default single line
diagram. The SLD view can also be accessed using
the Web browser-based user interface. The default
SLD can be modified according to user require-
PCM600. The user can create up to 10 SLD pages.
-
in the local mode, it can be operated only by using
the local front panel user interface. When the relay
is in the remote mode, it can execute commands
sent from a remote location. The relay supports the
input. This feature facilitates, for example, the use
of an external switch at the substation to ensure
that all relays are in the local mode during mainte-
nance work and that the circuit breakers cannot be
operated remotely from the network control center.
