7 - List of alarms and signals

LED view
Ekip Dip continuously monitors its own operating condition and that of all the devices to which it is connected. All the signals are available with the
front LEDs. The protection LEDs provide information with various combinations of lighting and flashing, while the power-on LED, as described on
page 34, indicates the power-on conditions of the trip unit.
NOTE: the number of LEDs depends on the version of Ekip Dip (LI, LSI, LSIG).
