most probably a temporary reduction of the insulation resistance

(for example the water seepage on the modules caused by

condensation). It is recommended to call qualified personnel to

perform an inspection of the installation in case this disconnection

events are recurrent. If the fault cannot be reset, that is causing a

ground fault or there is some other insulation breakdown.

If the signal cannot be reset, insulate AURORA on both Dc and

Ac sides so as to reach a safe condition; then contact an

authorized center for repairing the fault.

5) Malfunction-Fault Signal

Every time AURORA check system detects an operative

malfunction or fault, the yellow LED comes on and a message

showing the type of problem found appears on the LCD.

6) RS-485 Address Setting Signal

During installation, the yellow LED will flash until the address is

confirmed. For further information about setting the address, refer

to chapter 6.3.

7) AC grid voltage missing

When the system is normally activated and operating, if for any

reason there is a permanent loss of mains the inverter will signal

this fault status with the yellow LED on and green LED blinking.

This fault may be caused by a defective automatic circuit breaker

or a fault in the AC wiring to the inverter or a system fault in the

AC network.
