Description Possible Cause Things to Check Correction
330 POST RF AC volt-
age cut feedback
too low (A/D
channel 0)
Monitor senses
electrosurgical voltage out-
put too low during POST
test, indicating insufficient
voltage from HVPS, insuf-
ficient drive from the
RF Controller, failed RF
Amplifier, or a failed voltage
sensing channel.
The limits for this compari-
son are set when the system
enters calibration mode.
Configure the system for
Calibration mode operation and
initialize power.
Configure the system for test
mode operation and cycle power.
Measure HVPS output, RF
Amplifier drive, RF Amplifier
output, and voltage sensing
channel.
Replace the con-
troller assembly,
the HVPS, the
RF Amplifier, the
Transformer board
depending on the
specific cause of the
failure.
331 POST RF AC volt-
age cut feedback
too high (A/D
channel 0)
Monitor senses
electrosurgical voltage out-
put too low during POST
test, indicating insufficient
voltage from HVPS, insuf-
ficient drive from the
RF Controller, failed RF
Amplifier, or a failed voltage
sensing channel.
The limits for this compari-
son are set when the system
enters calibration mode.
See above. See above.
332 POST RF AC volt-
age coag feedback
too low (A/D chan-
nel 2)
Monitor senses
electrosurgical voltage out-
put too low during POST
test, indicating insufficient
voltage from HVPS, insuf-
ficient drive from the
RF Controller, failed RF
Amplifier, or a failed voltage
sensing channel.
The limits for this compari-
son are set when the system
enters calibration mode.
See above. See above.
333 POST RF AC volt-
age coag feedback
too high (A/D
channel 2)
Monitor senses
electrosurgical voltage out-
put too low during POST
test, indicating insufficient
voltage from HVPS, insuf-
ficient drive from the
RF Controller, failed RF
Amplifier, or a failed voltage
sensing channel.
The limits for this compari-
son are set when the system
enters calibration mode.
See above. See above.
