while the '*' character is displayed, the alpha-numeric data entry session is terminated. If the ENTER key

is depressed when the '*' character is not displayed, the cursor will advance to the right one space and

the user will be prompted again with the '*' character. If the ENTER key is depressed when the cursor is

in the tenth character position of the satellite name data field the entry is terminated.

RESET Mode

The RESET mode is used to display azimuth, elevation, and polarization drive fault conditions, and to re-

enable the drive outputs in the event the microcontroller has disabled an axis. When RESET mode is

activated, one of the following screens will be displayed.

AZ: OK EL: OK RESET

RESET AXIS: 1-AZ/EL

AZ: OK EL: OK PL: OK RESET

RESET AXIS: 1-AZ/EL, 2-POL

The first screen will be displayed if POL EQUIPMENT CODE CONFIG mode item is set to 0, the second

screen will be displayed if the POL EQUIPMENT CODE CONFIG mode item is set to 1 or 2.

The status of each axis is displayed after the appropriate banner (AZ:, EL:, or PL:) on the top line of the

LCD. If a fault exists for an axis, no movement may occur about that axis until the fault condition for that

axis is reset. Use the 1 key to reset the azimuth and elevation axes or the 2 key to reset polarization

axis.

Here are the status messages which may be displayed:

Indicates that no fault conditions are active for the axis (azimuth, elevation, or polarization).

JAMMED

Indicates that the antenna was commanded to move about the axis and no movement was

detected by the controller. This indicates either that the antenna did not move when commanded

to do so, or the sensor failed and the controller was not able to detect any movement (azimuth,

elevation, or polarization).

RUNAWAY

The drive was deactivated because the processor sensed movement for a drive which was not

commanded to move. This error is rarely caused by an actual runaway condition (the antenna

moving on its own). This error is usually due to a faulty sensor or noise pickup due to the sensor

shield not being connected properly. See Chapter 3 for proper shield connection instructions

(azimuth and elevation).

DRIVE

The axis was deactivated due to a drive fault condition (azimuth or elevation axis).

SENSOR

This error will occur if the antenna commands a polarization movement, and movement is

detected in the wrong direction. Note that a polarization jammed condition will occasionally

setup (polarization axis only).
