Open
ground
detector
(Power sup-
ply)
Hardware detects an open ground detector. This hardware problem
must be addressed before
it is safe to operate the
F6300.
When the F6300 clears
the error, it occurs again if
the hardware problem has
not been fixed.
+12 Volt fail
monitor
(DC power
supply)
Hardware disables amplifiers to prevent dam-
age to relays on the amplifier assemblies if Sys-
tem +12 V falls below a threshold of
approximately +5
volts.
Check the DC power sup-
ply.
Fan flow
monitor
error
Fans are blocked or inoperative. Verify fan operation (dis-
cussed earlier in this chap-
ter.)
Replace the fan assembly
if required. If the fans are
functioning, replace the
power supply circuit
board.*
Source Dis-
abled
One or more sources were disabled
by the hardware.
Verify the status of the
amplifier circuit boards
(discussed earlier in this
chapter.) Replace the
board if necessary. *
Over Tem-
perature or
fuse blown
(I AMP #4)
Amplifier in slot 5 is overheated or has a blown
fuse.
Replace the amplifier
board in slot 5.*
Over Tem-
perature or
fuse blown
(I AMP #5)
Amplifier in slot 6 is overheated or has a blown
fuse.
Replace the amplifier
board in slot 6.*
Over Tem-
perature or
fuse blown
(I AMP #6)
Amplifier in slot 7 is overheated or has a blown
fuse.
Replace the amplifier
board in slot 7.*
Over Tem-
perature or
fuse blown
(I AMP #7)
Amplifier in slot 8 is overheated or has a blown
fuse.
Replace the amplifier
board in slot 8.*
