9797A-27 C-Band TXRX
Installation
4-7
Remove the restraints from the antenna and verify that the antenna moves freely in azimuth, elevation,
and cross level without hitting any flanges on the radome.
4.8.3. Verify all assembly and Wiring connections
Verify that all pedestal wiring and cabling is properly dressed and clamped in place.
4.8.4. Balance Antenna Pedestal
Assure that the antenna assembly is balanced front to back, top to bottom and side to side by observing
that it remains stationary when positioned in any orientation. Refer to the Maintenance section for
complete information on balancing the antenna.
4.9. Power-Up The ADE
Turn Pedestal AC power breaker ON.
4.9.1. Initialization
Turn the pedestal power supply ON. The PCU will initialize the stabilized portion of the mass to be level
with the horizon and at a prescribed Azimuth and Elevation angles. The antenna will go through the
specific sequence of steps to initialize the level cage, elevation, cross-level and azimuth to predetermined
starting positions. Each phase must complete properly for the antenna to operate properly (post-
initialization). Refer to the initialization text in the Troubleshooting section in this manual. Observe the
Initialization of the antenna pedestal.
If any of these steps fail, or the ACU reports model "
xx
97", re-configure the PCU as described in the
Setup section of this manual. If initialization still fails, this indicates a drive or sensor problem, refer to the
Troubleshooting section.
4.9.2. Home Flag Position
Note the approximate position of the antenna relative to the bow of the ship while it is at the home switch
position. This information will be used later to calibrate the relative position display of the antenna.
4.9.3. BDE
Turn Power ON to the ACU. Record the power-up display, Master (ACU) Model & Software version and
the Remote (PCU) Model & Software version.
4.10. Setup
Refer to the Setup information in the next section of this manual and in the Setup section of your ACU
Manual.
