Section 5
Local HMI
There are 15 programmable indication LEDs on the front of the LHMI. Each LED can indicate three
states with the colors: green, yellow and red. The texts related to each three-color LED are divided
into three panels.
There are 3 separate panels 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 are lit according to priority, with red being the highest and green the lowest
priority. For example, if on one panel there is an indication that requires the green LED to be lit,
and on another panel there is an indication that requires the red LED to be lit, the red LED takes
priority and is lit. The LEDs can be configured with PCM600 and the operation mode can be
selected with the LHMI or PCM600.
Information panels for the indication LEDs are shown by pressing the Multipage button. Pressing
that button cycles through the three pages. A lit or un-acknowledged LED is indicated with a
highlight. Such lines can be selected by using the Up/Down arrow buttons. Pressing the Enter key
shows details about the selected LED. Pressing the ESC button exits from information pop-ups as
well as from the LED panel as such.
The Multipage button has a LED. This LED is lit whenever any LED on any panel is lit. If there are un-
acknowledged indication LEDs, then the Multipage LED blinks. To acknowledge LEDs, press the
Clear button to enter the Reset menu (refer to description of this menu for details).
There are two additional LEDs which are next to the control buttons
example, represent the status of a circuit breaker. The LEDs are controlled by the function block
OPENCLOSE_LED which must be configured to show the status of the breaker.
5.3 Keypad
The LHMI keypad contains push-buttons which are used to navigate in different views or menus.
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.
