This view provides information on the Tilt Sensor Bias, Conical Range, EL Adjust,
Rate Sensor, Search Parameter and Blockage Zone.
-Tilt Sensor Bias: This maintains the elevation and the cross level axes
in order to keep the pedestal parallel to the horizon. Adjust the two solid-
state tilt sensors to provide absolute cross-level tilt of the antenna and el
evation feedback to eliminate long-term pointing drift (error). Tilt bias
must be adjusted when the antenna control board or sensor box is
replaced. If the bubble on the button level located on the sensor box is
not centered, follow the following steps to adjust the tilt sensor bias.
· Step 1. Enter Setup MENU and press the “Ready” button to bring
the elevation and cross-level to 0.
· Step 2. Select “EL” from the drop down list and press Up and
Down arrow keys to adjust the bubble until it is located in the
center ring of the button level.
· Step 3. Select “CL” from the drop down list and press Up and
Down arrow keys to adjust the bubble until it is located in the
center ring of the button level.
