52 RC2000A Dual Axis Antenna Controller Chapter 6 Troubleshooting
AZIM SLOW SPEED, ELEV SLOW SPEED
The code entered by the user for the azimuth or elevation slow speed has been corrupted. Go to the
corresponding speed mode and reenter the slow speed code. See Section 4.8
AUTOPOL CONFIG DATA
The user has the option to configure the system for AutoPol ON or OFF, and to denote a HI or LO level
for the vertical polarization. If either of these values is corrupted, this error will appear. Go to CONFIG
mode and reenter the correct values. See Section 4.10.1
SIMULTANEOUS AZIM/ELEV
This error indicates that the value for the Simultaneous Az/El Enable CONFIG mode item has been
corrupted. See section 4.10.2.
GEO POSITION
The checksum associated with the GEO COUNT value does not agree with geo position in memory.
Move the antenna to the proper GEO POSITION and reenter the GEO ELEV POSITION in the CONFIG
mode. Section 4.10.4
COMM PORT
This alarm indicates that the checksums associated with the CONFIG mode Remote Mode Enable,
Comm Port Baud Rate, and Comm Port Address items indicate that at least one of these items is
invalid. See section 4.10.3.
AZ/EL ANGLE DISPLAY
This alarm indicates that the CONFIG mode items associated with the display of azimuth and elevation
position in an angle format have been corrupted. Please see section 4.10.6.
POL OPTIONS
This error indicates that at least one of the CONFIG mode items associated with the polarization control
and display options is invalid. If the system uses a polarotor, these items must still be initialized
properly to avoid this error. Please see section 4.10.7.
AZIM OPTIONS, ELEV OPTIONS
This error indicates that at least one of the CONFIG mode items associated with the azimuth or
elevation drive options are invalid. Note that all of the config mode items associated with these options
must be properly initialized even if the Az/El Drive Options Enable CONFIG mode item is disabled. If
this item is disabled and these errors occur, the 'Options Enable item should be enabled to gain access
to the other CONFIG mode items associated with these options. These other items can then be
initialized to their default values. See section 4.10.10 for default values.
6.2 OPERATIONAL TROUBLESHOOTING TIPS
THE CONTROLLER DOES NOT RETURN TO THE PROPER SATELLITE LOCATION (AND IS NOT
EVEN CLOSE)
When this occurs the controller is generally losing or gaining position counts for a given axis as the
antenna moves about that axis. Please review the items mentioned in Section 3.2 - Azimuth and
Elevation Position Sense.
If the cause of the problem is not found and only one axis is affected, consider replacing the position
sense module and/or magnets in the actuator. If both axis are affected the motor drive wires may have
