Local man machine
communication
When the MMI is unattended in normal operation, two things might
occur:
• No reporting of a disturbance (idle mode)
• Reporting of a disturbance (reporting mode)
When the terminal is in normal operation after the latest disturbance has
been acknowledged or no disturbance is stored in the memory, and no one
has attended the MMI for more than 45 minutes, the green LED remains
active. The yellow and red LEDs are dark and no text is shown on the dis-
play. The display is dark, with no light behind.
The display and LEDs will change their status when one of the buttons is
selected, or when a new disturbance is stored in the terminal memory.
When the terminal is in normal operation and a protection function has
operated since the latest reset of the indications, the MMI looks like this:
Green LED
Yellow and red LEDs
Disturbance summary
When the terminal is in configuration mode, the MMI looks like this:
