1.3. Loopdrive indications
Loopdrive modules feature multi-colour LED indicators with different colour and blinking cycles, which correspond to
currently detected state of the loudspeaker line.
General principle of LED indications:
BLUE
– system OK
ORANGE
– fault detected
Fault detection is always indicated by cyclic blinking. Blinking speed relates to the current status of the fault:
ORANGE fast
(4 cycles/sec) – fault is currently detected
ORANGE slow
(1 cycle/sec) – fault was detected in the past and fixed
Table 1. LDB indications
Blinking speed:
fast
=
4 blinks/s
slow
=
1 blink/s
very slow
=
1 blink/4s
Fault status:
active - fault is currently detected
memory - fault was detected in the past and fixed
