VLOC STATUS
ROM, XILINX, SYN LOCK, EEPROM:
Shows condition of various NAV receiver components.
These boxes
should be green, a red box indicates an internal failure.
MAIN STATUS
ROM, FPGA 1/3, EEPROM 1/2:
Shows the condition of various GIA 63/GIA 63W main board components.
These boxes should be green, a red box indicates an internal failure.
+5, +3.3, -5, +12/-12, +28 PWR RANGE:
Shows condition of various internal power supply ranges. They need
to be within 10% of desired voltages.
Replace the unit if these values are more than 10% from the desired
voltage.
AIRCRFT PWR A/B RNG:
Shows the technician that the main power inputs of the GIA 63/GIA 63W are within
acceptable ranges.
If a box is red, and the Aircraft PWR voltage is listed as 0 in the Analog Status box below,
check that all aircraft buses are on and GIA breakers are pushed in.
ANALOG CAL:
Shows the condition of the GIA calibration. (Green = Valid Analog Calibration)
OVER TEMP:
Informs the technician of an over-temperature condition on the GIA 63/GIA 63W main board.
(Red = Over-temperature, Green = Normal-temperature)
LOW TEMP:
Informs the technician of a low temperature condition on the main board.
(Red = Low-temperature, Green = Normal-temperature)
BKUP CAPS
:
Indicates status of the Backup Capacitor Test. A green box indicates the test passed, a red box
indicates it failed.
ANALOG STATUS
AIRCRFT PWR A, B:
Shows aircraft power input values, expressed in Volts DC.
(Example: 2214 = 22.14 Vdc)
TEMPERATURE:
Shows the internal temperature of GIA unit, expressed in degrees Fahrenheit. (Example:
12267 = 122.67°F)
DISCRETE
SYS ID PROG 1, 2:
Identifies the assigned GIA number when two or more GIA units are installed. Green
indicates that the System ID pin is left strapped to ground. Black indicates that the System ID pin is left ‘open’
and not strapped to ground. GIA #3 and GIA #4 are not used in SEP aircraft.
