2.4.2 LEDs
The LHMI includes three protection indicators above the display: Ready, Start and
Trip.
There are also 15 matrix programmable alarm LEDs on front of the LHMI. Each
LED can indicate three states with the colors: green, yellow and red. The alarm
texts related to each three-color LED are divided into three pages. Altogether, the
15 physical three-color LEDs can indicate 45 different alarms. The LEDs can be
configured with PCM600 and the operation mode can be selected with the LHMI,
WHMI or PCM600.
2.4.3 Keypad
The LHMI keypad contains push-buttons which are used to navigate in different
views or menus. With push-buttons you can give open or close commands to one
primary object, for example, a circuit breaker, disconnector or switch. The push-
buttons are also used to acknowledge alarms, reset indications, provide help and
switch between local and remote control mode.
The keypad also contains programmable push-buttons that can be configured either
as menu shortcut or control buttons.
