VERSION 2.0 2023-04-20 PAGE 3.1.29
PS Not Installed The PA power supply has been removed as
indicated by the absence of a grounded pin
connection on the power supply connector.
The PA Power Supply is installed, and the
present pin has been grounded by the power
supply.
Install Power supply.
Verify there is no obstruction in the
power supply connector.
The PS Present pin is measured using an
ADC on the Power Supply Interface PWB.
If problems persist check connections to
this board.
SCA MPX 1/2 Low Composite The MPX1/2 input level has fallen below the
user configured low audio threshold for longer
than the user configured timeout.
The MPX1/2 input must be configured as a
composite SCA source in the active preset for
this alarm to trigger.
The SCA MPX 1/2 Low Alarm must be enabled
in the active preset for this alarm to occur.
This alarm will clear immediately when the
MPX1/2 input level has increased above the
configured threshold.
Performing an alarm reset will clear this alarm
and reset the timeout.
Check the composite feed connected to
the MPX1/2 input. The most likely cause
of this alarm is an interruption in
composite distribution to the transmitter.
Verify that the threshold level
programmed in the active preset is below
the normal input level by checking the
MPX1/2 meter.
Verify that the configured timeout is long
enough to cover any silence or dips in
signal level.
SCA1 AES1 Left Low Audio The AES1 Left audio input level has fallen
below the user configured low audio
threshold for longer than the user configured
timeout.
The AES1 input must be configured as a SCA
source in the active preset for this alarm to
trigger.
The SCA 1 Low Alarm must be enabled in the
active preset for this alarm to occur.
This alarm will clear immediately when the
AES1 left input level has increased above the
configured threshold.
Performing an alarm reset will clear this alarm
and reset the timeout.
Check the audio feed connected to the
AES1 input. The most likely cause of this
alarm is an interruption in audio
distribution to the transmitter.
Verify that the threshold level
programmed in the active preset is below
the normal input level by checking the
AES1 Left meter.
Verify that the configured timeout is long
enough to cover any silence or dips in
signal level.
