Turn the pedestal power supply ON. The brakes on the Elevation and Cross-Level motors will release. A
brake release power supply control circuit supplies 24 VDC to the brakes initially (5-10 seconds) and then
reduces the voltage to 12VDC. The PCU will initialize the stabilized portion of the mass to be level with the
horizon and at a prescribed Azimuth and Elevation angles in the specific sequence of steps listed below.
Antenna Initialization
Initialization is completed in the following phases, each phase must complete correctly for the antenna to
operate properly (post-initialization). Observe the Initialization of the antenna pedestal.
Step 1. Elevation axis activates - Input from the Elevation sensor is used to drive the Elevation of
the equipment frame to 45.0 degrees in elevation.
Step 2. Cross-Level axis activates - Input from the Cross-Level sensor is used to drive Cross-Level
of the equipment frame to bring it to level (this results in the tilt of the Cross-Level Beam being
level).
Step 3. Azimuth axis activates - Antenna drives CW in azimuth until the “Home Flag” signal is
produced. This signal is produced by a Proximity sensor in close proximity to a metal tab. After a
short period of time (a total of approximately 1-2 Minutes after power is initially applied to the
antenna), the PCU will report its model setting and software version number to the Antenna
Control Unit (ACU).
This completes the phases of initialization. At this time the antenna elevation should be at 45.0 degrees
and Relative azimuth should be at home flag (proximity sensor at the trailing edge of the metal tab in the
azimuth assembly).
