List Of Alarms And Signals - ABB Sace Emax 2 Installation, Operation And Maintenance Instructions

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 by means of different lighting and flashing combinations, while the power-on LED
indicates the power-on state of the release.
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
