plate to correct this. By making a small positive angle change to Azimuth Origin this
mechanical tolerance can be corrected. Typically 1 or 2 degrees is sufficient. After
making this setting, raise Elevation 75 degrees and stow the Dish to test Azimuth center.
Repeat the process until the Azimuth Stow is centered properly.
The G74, and G75 mounts move the Dish Azimuth to a physical current stall at the
Azimuth down limit before allowing the Elevation to move down to the Stowed position.
If the Azimuth current stall position is off by several degrees then it is possible for the RF
Assembly arms to be off centered in the Roof Mounting Plate and actually rest on one of
the rails extending the length of the plate. If this happens the dish will not stow fully
down onto the roof. There are mechanical adjustments that can be made to correct this
Azimuth Offset. Loosen the 8 ¼-20 Cap Screws that secure the Dish Mount to the Roof
Mounting Plate and rotate the Dish mount to center the Azimuth Stow position. Only use
the Azimuth Origin Configuration adjustment as a short term solution until the
mechanical solution can be accomplished.
The XF2 and XF3 mounts move the Dish Azimuth to a physical current stall at the
Azimuth down position then move back in a positive (up) direction approximately 2.5
degrees to an electronic limit before allowing the Elevation to move down to the Stowed
position. If the Azimuth current stall position is off by several degrees then it is possible
for the RF Assembly arms to be off centered in the Roof Mounting Plate and actually rest
on one of the rails extending the length of the plate. If this happens the dish will not stow
fully down onto the roof. There are mechanical adjustments that can be made to correct
this Azimuth Offset. Loosen the 8 ¼-20 Cap Screws that secure the Dish Mount to the
Roof Mounting Plate and rotate the Dish mount to center the Azimuth Stow position.
Only use the Azimuth Origin Configuration adjustment as a short term solution until the
mechanical solution can be accomplished.
Elevation Origin
The Elevation Origin sets the correct Search Elevation value for the type of Dish
Mount when the Mount is placed on a level platform. When Elevation Origin is
set properly, both Dish Elevation and Target Elevation values displayed on the
HTML Main Status Page show the same approximate value when locked onto the
Target Satellite.
Note: Make sure the Dish Mount is installed on a level platform or vehicle and the
platform or vehicle is setting on a level surface before setting Elevation Origin.
Depending on type of Dish Mount the J1 controller will set a default Elevation
Origin value in configuration. This value can be changed and exported to a
configuration file.
To adjust Elevation Origin the Dish Mount must be locked to a valid (Target)
satellite.
