LEDs

The LHMI includes three protection status LEDs above the display: Normal, Pickup 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 and can be browsed with the Multipage button.
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.
There are two additional LEDs which are embedded into the control buttons
represent the status of the circuit breaker.

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 a grounding 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
