Lights if primary power fails, and the system is on Battery Backup.
Lights when the Battery (if installed) voltage drops below 24 VDC which roughly indicates 50% of backup
capacity remaining. This may occur as a result of normal discharge in a backup situation, Battery
exceeding its useful life, or a Battery failure such as water loss or shorted cell.
In addition, while running on Battery Backup, If the Battery drops below 22 VDC, the LED will begin to blink
indicating that self-shutdown is imminent. If the Battery drops below 21 VDC the BDA will shut down
completely to protect the Battery from damaging deep discharge.
Lights if the Uplink PA (Power Amplifier) is enabled and has an overcurrent, undercurrent, or internal fault .
Lights if the Downlink PA is enabled and has an overcurrent, undercurrent, or internal fault .
Lights to indicate that an Input Signal of sufficient strength is present to cause the AGC circuit (if enabled)
to act to reduce gain. The level at which AGC action occurs is not a fixed signal level. It depends upon the
user setting for output level target. When lower targets are set, the AGC will begin to act at lower input
levels. When AGC is disabled, the LED does nothing. If the Input Signal exceeds the AGC ability to reduce
gain, an overload condition exists, and the AGC LED blinks rapidly.
Operates the same as the Uplink AGC LED, but for the Downlink.
Lights when the BDA system temperature, as detected by a digital sensor in the fault monitor, exceeds the
user programmed high temperature threshold.
Lights when the Cooling Fan(s) (if enabled) have an overcurrent or undercurrent condition.
The Buzzer sounds briefly during button presses for audible feedback. Where a User Function requires a
confirmation, a short beep is emitted. During a Fault Condition, a long periodic beep is sounded (this can
be disabled). When the Battery is about to be depleted when on Battery Backup Power, the Buzzer will
sound continuously.
Power Switch for turning the BDA operation on and off. Note that this only controls the BDA Controller,
Boosters, PA's, and Fans; the DC Power Supply is still operating.
This Button is used to enter the Main Function Menu and Submenus, and where applicable to confirm a
Function selection chosen with the Adjust Buttons.
This Button is used to cancel any Function changes, reverting to previous settings. If a Fault has occurred
and its Status is displayed, pressing the Exit Button clears the fault.
These buttons Scroll up and down between Status, Function, and Menu display items. They also adjust
programmable numeric values up and down.
