Installation and operating manual
(PVI-3.8/4.6-I-OUTD Rev.: 1.5)
V 5) Anomaly-Fault indication
Each time that AURORA's check system detects an anomaly or
G
fault in the operation of the monitored system, the yellow LED
R
lights up continually and a message indicating the type of
problem detected will appear on the LCD display.
V 6) Internal ventilation system anomaly
Indicates that the ventilation system is not woking correctly. This
G
should not cause problems as the fan is only activated when high
R
temperatures are combined with high output power.
7) Grid disconnection
When the system is functioning normally and a grid failure event
V
occurs, the yellow LED will immediately light up with a steady
G
light, and the green LED will flash.
