5 - 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 22, indicates the power-on conditions of the trip unit.
NOTE:
the number of LEDs depends on the version of Ekip Dip (LI, LSI, LSIG).
Summary table of LED signals
The following table summarises the signals available with the protection LEDs and the operations to be carried out in response to alarms or fault
conditions signalled.
