Preliminary Check; Operation - Honeywell KHF 1050 System Installation Manual

Preliminary - Subject to Change Without Notice
2.A. Preliminary Check
1. Prior to turning the system on, ensure that all connectors
are properly seated in their proper location.
2. Turn the system on. As the system turns on it performs a
brief self-test.
Normally, after a few seconds, the HF controller (or HF
window of a multi-function controller) will show an HF
operating frequency, mode of operation and other operating
parameters. Refer to the operating manual for the specific
controller for specific operation and the information
available on the display.
3. Push the TEST button on the controller to perform a system
test. The pilot-activated self-test takes approximately
15 seconds to complete.
4. KXR 1053 Receiver/Exciter Built-In-Test
The receiver/exciter design incorporates provisions for
monitoring its own operation to detect any condition or
occurrence that the operator (a flight crew member) might
observe and interpret as a reason for requesting a
maintenance action.
These maintenance observations are stored in non-volatile
memory within the receiver/exciter so they can be
retrieved with appropriate test equipment.
If a sufficiently serious fault is detected, the
"receiver/exciter status" bit of the Maintenance Status
message, label 351, is set to indicate a fault.
The maintenance data collection provision includes the
following three types of monitoring: Power-On, Continuous
Monitoring and Initiated Tests. The BITE tests that shall
be performed at system turn-on, at pilot activated, or
continuously are summarized in Table 1001. The table shows
which tests are performed for each of the three types of
monitoring.
