4 - 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 19, 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.

(1) The temperature alarm is signalled by lighting of the protection L and I red LEDs.
(2) The last trip can also be displayed with trip unit off, by pressing the iTest key.
(3) The Hardware Trip is signalled by lighting of the pre-alarm L yellow LED and the protection I red led.
(4) Five flashes when self-test is started up
(5) Error present with one of the three flashing options displayed alongside.
Key to LED colours
The above table lists the colors of the LEDs, to be interpreted as follows:
• R = red LED (alarm LED L, S, I, G).
• G = yellow LED (pre-alarm LED L).

NOTE: for further details refer to the table listing the components of the interface, available on page 18.
