Local HMI

The LHMI uses rugged 7-inch high resolution color screen with

capacitive touch sensing technology. The user interface has

been carefully designed to offer the best situational awareness

to the user. Visualization of the primary process measurements,

events, alarms and switching objects’ statuses makes the local

interaction with the relay extremely easy and self-evident. The

LHMI provides a control point for the selected primary devices

via pop-up operator dialogs.

Additionally, the LHMI supports the engineer during the relay’s

testing, commissioning and troubleshooting activities. The

information, traditionally accessible through different paths

within the menu structure, is provided in collectively grouped

and visualized format.

The Home button at the bottom of the LHMI indicates the

relay’s status at a glance. In normal situations, the Home button

shows a steady green light. Any other situation that requires the

operator’s attention is indicated with a flashing light, a red light

or a combination of these.
