1
AC Circuit Breaker
2
FEU Failure
When on, indicates the dc output voltages for the
FEU are below the specified minimum.
3
FEU OK
When on, indicates the dc output voltages for the
FEU are above the specified minimum.
4
DC3 Failure
When on, indicates that one of the +3 Vdc output
voltages is not within the specified tolerances.
5
DC3 OK
When on, indicates that the +3 Vdc output voltages
are within the specified tolerances.
6
AC Present
When on, indicates ac power is present at the ac
input connector, regardless of the position of the
circuit breaker.
7
DC5 Failure
When on, indicates that one of the +5 Vdc output
voltages is not within the specified tolerances.
