8.11.2 Fault analysis
The indicator lights up when faults occur. The fault type is indicated when
called.
To do this, perform a LED and buzzer test [➙ 89]. When the LED test sequence
has finished, the "fault indicator" lights up together with the relevant LED for
approximately 3 seconds.
Fault types

You will find a graphic containing the fault types in the Annex [➙ 109]. The graphic
can be printed out and kept right next to the LEDs. This makes it easier to identify
the fault type.
