1.1 Relay Menus And Display
All relay fascias have the same appearance and support the same access keys. The basic menu structure is also
the same in all products and consists of four main menus, these being,

Instruments Mode - allows the user to see the conditions that the relay is experiencing i.e. current, voltage etc.
Fault Data Mode - allows the user to see type and data of any fault that the relay has detected.
Control Mode - allows the user to control external plant under the relays control for example the CB
All menus may be viewed without entering a password but actions will not be permitted if the relevant passwords
have been set.

This document describes the text descriptions as they appear in the menu structure when the relay is using the
default files. The user can programme the relay to use alternative text descriptions by installing user language
files through the Reydisp Evolution software language configuration tool – see 2.1.5

To change the contrast on the LCD insert a flat bladed screwdriver into the screwhead below the contrast symbol,
turning the screwhead left (anti-clockwase) lightens the contrast of the LCD and turning it right (clockwise)
darkens the display.
