If the power supply is ruled out and this is the only module with this fault,
the module should be swapped with another to rule out the slot into which
the module is plugged. If the fault follows the module then it should be sent
in for repair.
6.2.3.10 Under Voltage
+32V source is below 30 V. Module does 3-strike and then fault is latched. Most likely
a power supply problem (not actually a PA module issue). Check the following:
•
Check the other module associated with that power supply to see if it is also
faulted. If 2 modules have this fault, then check the power supply voltage
readings the GUI and try swapping the supply with another. Remember that
each odd numbered module is powered from the same supply as the next
highest even numbered module, 1&2, 3&4 etc...
If the power supply is ruled out and this is the only module with this fault, the module
should be swapped with another to rule out the slot into which the module is plugged. If
the fault follows the module then it should be sent in for repair.
6.2.3.11 Over Current
Total current on +32V line has exceeded 75A. Module does 3-strike and then fault is
latched.
6.2.3.12 Over Temp
Module temperature has exceeded 95
o
C (76
o
C for the low power DCD module).
Module does 3-strike and then fault is latched.
6.2.3.13 High VSWR
Internal reflected RF too high. About 200W of reflected power. Module does 3-strike.
