Relay Menus And Display

All relay fascias contain the same access keys although the fascias may differ in appearance from model to
model. The basic menu structure is also the same in all products and consists of four main menus, these being,
Settings Mode - allows the user to view and (if allowed via the settings mode password) change settings in the
relay.
Instruments Mode - allows the user to view the relay meters e.g. current, voltage etc.
Fault Data Mode - allows the user to see type and data of any fault that the relay has detected.
The menus can be viewed via the LCD by pressing the access keys as below,
Pressing CANCEL returns to the Relay Identifier screen
