Switching power supply LEDs
Each switching power supply contains two LEDs that provide specific status indications.
The
AC OK
LED indicates the status of the incoming ac source to the supply. The LED is green
when the ac source is at its normal operating level (between 175 and 180 V ac) and off when the ac
source is below an acceptable level or is not present.
The
DC OK
LED indicates the status of the dc output of the supply. The LED is green when the dc
output is within the adjustable range of its operation limits and off when the dc output is outside the
limits of normal operation.
Exciter LEDs
The front panel of each exciter contains two LEDs that provide specific status and alarm indications.
The upper LED indicates the status of the exciter’s operating power. The LED is on (green) when the
exciter’s logic supply is enabled and operating at an acceptable level.
The lower LED indicates the RF operating status of the exciter; it has four different appearances:
– Green: the exciter is operating normally.
– Green/ing amber: the exciter is operating (and producing RF output), but has a non-
inhibiting system fault (e.g., audio loss or low input level) and requires checking. The
transmitter will likely continue to operate.
– Amber: the exciter has been inhibited by the controller (e.g., RF mute).
– Red: the exciter has been inhibited by a fault occurring within the exciter.
