6.1 Introduction
This section contains diagnostic and troubleshooting information for the Atlas
Series UHF transmitter. Included is a complete description of all faults which can be
displayed via the transmitter front panel display or GUI (Graphical User Interface).
Due to the complexity of the control system and the extensive use of surface mount
components, the scope of this diagnostics section is to isolate the problem down to a
PC board or module which can then be easily exchanged.
The GUI buttons and icons use a symbol and color code system. Some examples are
given below:
a. Green with a 1 (or bar) - ON and operating normally.
b. Dark Gray with an O - Shut off (not faulted off)
c. Light Gray - "Grayed Out" - Not communicating or not available.
d.
Yellow - Warning - A non-critical sub-system or parameter is out of tolerance
and should be addressed by engineering personnel.
1.
Yellow with a 1 (or bar) - Warning condition - Still on
2.
Yellow with an O (circle) - Warning condition - Shut off
e. Red - Critical fault - This could be a sub-system fault in which the sub-system
is muted or shut off (such as a PA Module) or could be a system level fault
which could mute or shut the transmitter off.
1.
Red or Red with an O (circle) - Critical Fault - Shut off
When a fault occurs one of the LEDs next to the five Quick buttons will illuminate
RED. To track down the cause of the fault, press the quick button. This will take
you to one of the 5 main menu screens. There will be a red button or icon on this
screen which will allow you to track the problem deeper into the system. The other
option is to start by going to the System Log and seeing what faults have occurred
and in what order. If you are not familiar with GUI navigation, refer to Section 3.
