Figure 11: 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.
5.5.1.2 LEDs
The LHMI includes three protection status LEDs above the display: Ready, Start and
Trip.
There are 15 programmable alarm LEDs on the 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.
There are 3 separate pages of LEDs available. 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.
5.5.1.3 Keypad
The LHMI keypad contains push-buttons which are used to navigate in different
views or menus. With the push-buttons you can give open or close commands to one
primary object, for example, a circuit breaker, disconnector or an earthing 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.
