9711-92 Ku-Band TXRX Installation
3-33
Energize and check the other Below Decks Equipment to verify that all the equipment is operating. You will need to
assure that the ACU is setup correctly and that the antenna acquires the correct satellite before you will be able to
completely check all the below decks equipment for proper operation.
3.9. Cable Terminations
3.9.1. At The Radome
The TX and RX, or TVRO IF, cables must be inserted through the cable strain reliefs at the base of the radome.
Apply RTV to the strain relief joints and tighten the compression fittings to make them watertight. Attach the
pedestal cable adapters to the TX and RX, or TVRO IF, cables from below decks. Refer to the System Block
Diagram.
AC Power cable for the Antenna Pedestal and RF Equipment is routed into the AC Power Breaker box and
connected to the breaker terminals.
Sea Tel recommends that separate, dedicated, AC Power be provided for the Marine Air Conditioner (Do NOT
combine with the AC Power provided for the Antenna Pedestal and RF Equipment). This AC Power cable is
routed into the Marine Air Conditioner and terminated to the AC terminals inside.
3.9.2. ACU & TMS
To Connect AC Power, Gyro Compass Connection and IF Input refer to the Antenna Control Unit manual.
Installation of optional (remote) Pedestal, and /or Radio, Monitor & Control connection(s) from a PC
Computer are also contained in the ACU manual.
3.9.3. Other BDE
Refer to the vendor supplied manuals for installation of the other BDE.
3.10. Final Assembly
3.10.1. Remove Stow Braces/Restraints
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.
3.10.2. Verify all assembly and Wiring connections
Verify that all pedestal wiring and cabling is properly dressed and clamped in place.
3.11. Power-Up The ADE
Turn Pedestal AC power breaker ON.
3.11.1. 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 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 "xx09", 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.
3.11.2. 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.
3.11.3. BDE
Turn Power ON to the ACU. Record the power-up display, Master (ACU) Model & Software version and the
Remote (PCU) Model & Software version.
