381
No tone feedback
during POST
The Monitor did not detect
tones during POST. This
typically occurs because of a
problem in the tone genera-
tion circuitry.
Listen for tones during POST.
Verify that all internal cables are
properly connected.
Increase the tone volume by
adjusting the Volume Control on
the back panel of the generator.
Cycle system power and deter-
mine if this error is repeated.
Configure system for test mode
operation.
Check the tone drive signal from
the Controller assembly while
the unit is activated. Lack of a
signal indicates a problem with
the Controller assembly.
Check for a proper TONE_
MON signal to the control-
ler. Lack of a signal indicates
a problem with the Back Panel
assembly.
Replace the
Controller assembly.
Repair or replace the
Back Panel assembly.
382
Activation without
a tone
The Monitor did not detect
a tone during activation.
This typically occurs because
of a problem in the tone
generation circuitry.
Listen for a tone during activa-
tion.
Verify that all internal cables are
properly connected.
Increase the tone volume by
adjusting the Volume Control on
the back panel of the generator.
Cycle system power and deter-
mine if this error is repeated.
Configure system for test mode
operation.
Check the tone drive signal from
the Controller assembly while
the unit is activated. Lack of a
signal indicates a problem with
the Controller assembly.
Check for a proper TONE_
MON signal to the control-
ler. Lack of a signal indicates
a problem with the Back Panel
assembly.
Replace the
Controller assembly.
Repair or replace the
Back Panel assembly.
383
RF Current sensed
at an unselected
output.
The Monitor has sensed cur-
rent flowing at an output
that has not been selected.
This may indicate a faulty or
stuck output relay.
Arrange the system with fixed
loads connected to all outputs.
Activate each output in turn
while monitoring all outputs for
current.
Replace or repair the
Output assembly.
Replace the
Controller assembly.
