Figure 6: Alarm LED panel
The function button and alarm LED panels are not visible at the same time. Each panel
is shown by pressing one of the function buttons or the Multipage button. Pressing the
ESC button clears the panel from the display. Both the panels have dynamic width that
depends on the label string length that the panel contains.

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 alarm texts related to
each three-color LED are divided into three pages and can be browsed with the
Multipage button. Altogether, the 15 physical three-color LEDs can indicate 45
different alarms. The 15 physical three-color LEDs in one LED group can indicate 45
different signals. Altogether, 135 signals can be indicated since there are three LED
groups. The LEDs can be configured with PCM600 and the operation mode can be
selected with the LHMI or PCM600.

Keypad

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.
