Controls and Indicators
Indicator LEDs
Three LEDs located on the front panel of the ALM indicate the relay control
signal status from the inverter.
NOTE: The LEDs are unaffected by the ALM’s switch
positions or fuse condition.
AUX RELAY 9 LED
The yellow LED indicates whether relay RY9 has engaged or not. If this LED is
illuminated, the N.O. to COM contacts are connected. If this LED is not illuminated,
the N.C. to COM contacts are connected.
AUX RELAY 10 LED
The green LED indicates whether relay RY10 has engaged or not. If this LED is
illuminated, the N.O. to COM contacts are connected. If this LED is not illuminated,
the N.C. to COM contacts are connected.
INVERTER OPERATIONAL LED
The blue LED indicates the inverter’s operational status. If the inverter is
powered and ready for operation, the blue SYSTEM OPERATIONAL LED turns ON as
soon as the phone-type cable is plugged into the inverter. If the blue LED does not
turn ON, the inverter is either not powered, is set to the CHG-only mode without any
utility pass-through, or has no AC output which may be caused by an error
condition.
