Overall System Theory

Detailed RF Theory of Operation
The exciter theory is described in a separate technical manual included with the
transmitter. Each of the remaining RF sections of the transmitter are described in the
following paragraphs.
4.3.1
Exciter Operation
The exciter output is basically fixed and should not require adjustment. The exciter
power output is set using the controls on the front of the exciter and should be set to
the “Exciter Power” reading on the factory test data sheet for the transmitter. For
information on setting exciter power, refer to the exciter manual.
4.3.1.1 Automatic Exciter Switching
If a second or backup exciter is installed and the on air exciter fails, the controller
will automatically switch to the backup exciter and log the fault. Note that the
controller will wait 10 seconds for the on-air exciter to recover before switching to
the backup. If a backup exciter is added anytime after factory testing, the installer
must go into the Configuration Menus on the Diagnostic Display and set “ALT
EXCITER” to YES to let the controller know that the backup exciter exists. If this is
not done the controller will not auto switch.
4.3.1.2 Manual Exciter Switching
For dual exciter configurations, the on-air exciter can be selected manually using
the Exciter Status Screen in the Diagnostics Display [STATUS D,C] see Figure 4-2.
Manual exciter switching can also be done via the configurable remote input. See
Table 2-1 in Section II for more information on this remote control input.
