388
POST monitor
timed out- did not
respond to a POST
command
Reset machine and if
error repeats, then replace
Controller Assembly
Cycle system power and deter-
mine if this error is repeated.
Replace the
Controller assembly.
389
Dial setting over
maximum limit
The front panel power set-
ting exceeds the limit for the
selected mode.
Cycle system power and deter-
mine if this error is repeated.
Replace the
Controller assembly.
391
Monitor detected
the wrong RF
waveform
The Monitor has detected
an improper RF Amplifier
drive waveform or frequency
for the selected mode.
Cycle system power and deter-
mine if this error is repeated.
Replace the
Controller assembly.
392
Monitor detected a
pulse mode on-time
that was too long
The active pulse mode
pulses are longer than the
nominal duration limits.
Cycle system power and deter-
mine if this error is repeated.
Replace the
Controller assembly.
393
Vbias signal too
high
The reference voltages on
one or more of the ADCs
on the Controller are too
high.
Verify 2.5VDC on the voltage
sense pins of the ADC when the
system is not activated.
Verify that all cables are properly
connected.
Replace the
Controller assembly.
394
Vbias signal too
low
The reference voltages on
one or more of the ADCs
on the Controller are too
low.
Verify 2.5VDC on the voltage
sense pins of the ADC when the
system is not activated.
Verify that all cables are properly
connected.
Replace the
Controller assembly.
