7200 TROUBLESHOOTING
E - 10
Intelsat pre-epoch prediction (Applies to: All systems tracking Intelsat targets)
Description: This fault occurs when the Intelsat data set in the 7200 ACU is
valid in the future but not at the present moment. Using the future
data set given, the 7200 ACU automatically back calculates the
satellites current location and points the antenna in that direction.
To Correct: Check to ensure that the UTC time shown on the 7200 ACU is
correct. Enter a currently valid data set or wait until the future set
is valid.
Invalid target in target schedule (Applies to: All systems)
Description: This fault occurs when a target is placed in the target scheduler
and then the target is deleted.
To Correct: Create a new target with the same name as the one in the target
scheduler.
Keyboard Stop (Applies to: 7200 ACU)
Description: This status occurs when the Stop button on the 7200 ACU is
pressed and thus tracking is halted.
To Correct: Press the Resume [shift - Stop] key and then tracking is resumed.
Low Tracking Signal Level (Applies to: All systems when operating in a tracking
mode.
Description: This fault occurs when the signal level from the tracking receiver is
lower than the minimum level set in the steptrack parameters
menu.
To Correct: Check the Low Tracking signal level and ensure that it is set much
lower than the peak value in dB (a value about 1 dB above the first
sidelobe is recommended, about -10 dB). If this value is set
properly, then determine what has caused the signal level to drop
and correct as required.
Non-volatile RAM corrupted (Applies to: All systems)
Description: This fault occurs when the RAM that stores the parameters does
not have matching checksums.
To Correct: This fault can only be corrected by manually checking all the
parameters and modifying the default parameters back to the
desired setting.
