User interfaces and menu structure

The settings and functions of the MiCOM protection relay can be accessed both from the
front panel keypad and LCD, and via the front and rear communication ports. Information on
each of these methods is given in this section to describe how to get started using the relay.

Introduction to the relay

1.2.1

Front panel

The front panel of the relay is shown in the following figures, with the hinged covers at the
top and bottom of the relay shown open. Extra physical protection for the front panel can be
provided by an optional transparent front cover. With the cover in place read only access to
the user interface is possible. Removal of the cover does not compromise the environmental
withstand capability of the product, but allows access to the relay settings. When full access
to the relay keypad is required, to edit the settings, the transparent cover can be unclipped
and removed when the top and bottom covers are open. If the lower cover is secured with a
wire seal, this will need to be removed. Using the side flanges of the transparent cover, pull
the bottom edge away from the relay front panel until it is clear of the seal tab.
The cover can then be moved vertically down to release the two fixing lugs from their
recesses in the front panel.
