Chapter 11. Current Fault Status
XSAT#: (XSAT1/XSAT2) Sets the currently selected XSAT. The Currently Selected XSAT is
used in several menus (in 1:1 mode only) that allows the user to view or change most
parameters of the Currently Selected XSAT.
Note: This selection is not to be confused with the Online XSAT selection in the
Redundancy controller section.
XSAT Internal Voltages:
The XSAT unit monitors the 5 internal DC voltages: 24,20,12,+5, and –5 for the Currently
Selected XSAT. The monitor circuitry will display a fault (FT) if any of these voltages are +/-
10% out of range. These voltages are updated when the Current Fault Status screen is entered, or
if the Currently Selected XSAT is changed, or if the (GET DATA) button is pressed.
Lock Detects: The XSAT monitors the 4 phase
lock loops (PLLS) for each XSAT. A fault is
displayed for any and each PLL that is not
locked. These lock statuses are updated when
the (GET DATA) button is pressed, or as in the
above section.
Currents & Temperatures:
The LNA is monitored for excessive and low
currents. A fault is displayed if these currents
are out of their prescribed window.
If the temperature rises out of specification for
the XSAT, a fault will appear in the Heat Sink
field. As the Heat Sink temperature continues
to rise, the XSAT will automatically disable the
FET amplifiers and display a shutdown fault.
Processor: The Chksum (checksum), IIC Bus,
and the battery is monitored for proper
operation and will display a faulted condition
(FT) when the processor system is not
functioning properly.
