LEDs

The LHMI includes three indicators above the display: Ready, Start, and Trip. The
load shed start (initiation of power balance calculation) and operate (initiation of load-
shed commands) are mapped to LHMI Start and Trip LEDs respectively.
There are also 15 matrix programmable alarm LEDs in front of the LHMI. Each LED
indicates three states with the colors: green, yellow and red.

The LHMI keypad contains push-buttons which are used to navigate in different
views or menus. The push-buttons are used to acknowledge alarms, reset indications,
provide help, make new settings and confirmations.
The keypad also contains programmable push-buttons that can be configured either as
menu shortcut or control buttons.
