Exciter Front Panel Alarm Checks
There are two LEDs on the left-hand side of the Exciter that provide information about its operational
status - Power and Status (see
Figure 4.1.4 ). The Power LED will illuminate green when a valid LVPS
input voltage is applied to the A2J1 connector and +5V is present to power the LED. The tri-color Status
LED can be green, amber or red and be solid or blinking.
When the Status LED is:
 Green (solid) - exciter is operational, with no known faults
 Amber (solid) - controlled inhibit
 Red (solid) - inhibiting fault
 Green/Amber (blinking) - exciter is operational with non-critical faults
 Green/Red (blinking) - exciter is operational with critical faults
 Amber/Red (blinking) - inhibiting fault (latching)
