13. Inspect the alignment of the belt through the motor drive sprocket and the driven sprocket. Mis-
alignment will cause the
belt to wear along its
edges.
14. Inspect the belt teeth for
damage. Look for teeth
that have de-laminated
from, or been completely
torn off, of the belt.
15. Inspect the Elevation
Motor and belt. Assure
that there are no loose
motor mounting
hardware. Check the
motor cable for damage
and that the retaining
screws are tightened to
keep the connector
properly terminated.
CAUTION:
Be EXTREMELY careful rotating the pedestal around while you fingers are in
this area to prevent pinching or crushing your fingers in the pedestal
assembly.
16. Inspect the alignment of the belt through the motor drive sprocket and the driven sprocket. Mis-
alignment will cause the belt to wear along its edges.
17. Inspect the belt teeth for damage. Look for teeth that have de-laminated from, or been completely
torn off, of the belt.
18. Inspect all harnesses and connections - The harnesses should not be frayed and all the connectors
should be properly fastened and retainer screws tightened.
19. Inspect the PCU to assure that all mounting hardware is secure and all the connections are tight.
20. Inspect all hardware, checking for any loose hardware, loose assemblies (PCU, Power Supply, BUC or
Motor Driver) or counter-weights. Re-apply Loctite to, and properly tighten, any loose mounting
hardware found.
21. Inspect waveguide sections, especially flexible sections, immediately replace any cracked,
discolored/burned or broken sections. Do NOT use Loctite on any loose waveguide connecting
hardware.
22. Inspect the perimeter of the dish for any damage that would indicate that the dish may have
impacted the inside surface of the radome top,
23. Inspect the feed assembly on the back side of the dish to verify that none of the feed, polarization
motor or LNB hardware is loose. Check the coax connector on the end of the LNB to assure that it is
properly tightened.
6.4.3.
Turn the pedestal power supply ON … set PCU Config to N0000 but do NOT save … Disconnect the TXIF cable
from the bracket at the base of the radome to assure that TRANSMIT is disabled.
Mechanical Checks
1. Inspect inside of radome for signs that the dish or feed have been rubbing against the inside of the
fiberglass radome.
2. Rotate the pedestal through its full range of azimuth motion (unlimited 360 degrees rotation). The
antenna should rotate freely and easily with light finger pressure. There should not be any
mechanical or cable restrictions to prevent it rotating full 360 degree rotation with no resistance or
drag.
3. Rotate the pedestal through full range of elevation rotation (-15 to +105). The antenna should
rotate freely and easily with light finger pressure.
