7.3 BDA Controller User Interface
LED and Audible Indicators:
LED and audible indicators are used to enhance the user interface of the BDA. 10 LEDs
and buzzer are described below:
PWR FAIL Lights if primary power fails, and the system is on Battery Backup.
BATT 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.
UPLINK BOOST Lights if the Uplink Amplifier is enabled and has an overcurrent,
undercurrent, or internal fault.
UPLINK PA Lights if the Uplink PA (Power Amplifier) is enabled and has an
overcurrent, undercurrent, or internal fault.
DNLINK BOOST Lights if the Downlink Amplifier is enabled and has an overcurrent,
undercurrent, or internal fault.
DNLINK PA Lights if the Downlink PA is enabled and has an overcurrent,
undercurrent, or internal fault .
UPLINK AGC 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.
DNLINK AGC Operates the same as the Uplink AGC LED, but for the Downlink.
TEMP Lights when the BDA system temperature, as detected by a digital
sensor in the controller, exceeds the user programmed high temperature
threshold.
FAN Lights when the Cooling Fan(s) (if enabled) have an overcurrent or
undercurrent condition.
BUZZER The Buzzer sounds briefly during button presses for audible feedback.
When 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.
