Err
Code
Description Possible Cause Things to check Correction
320 Monitor failed
program CRC
test
Errors found in software
downloaded from the System
Controller to the Monitor dur-
ing initialization.
Cycle system power and deter-
mine if this error is repeated.
Replace the Control/
Display Board.
321 Monitor failed
calibration data
CRC test
Monitor calibration data is cor-
rupted.
Recalibrate all system modes. Replace the Control/
Display Board.
322 Monitor or RF
controller did
not return to
IDLE state
Activation continues after acti-
vation command ceases.
Cycle system power and deter-
mine if this error is repeated.
Replace the Control/
Display Board.
330 POST RF AC
voltage cut feed-
back too low
Monitor senses electrosurgical
voltage output too low during
POST, indicating insufficient
voltage from HVPS, insufficient
drive from the RF Controller,
failed RF Amplifier, or a failed
voltage sensing channel. The
limits for this comparison are
set when the system enters cali-
bration 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 Control/
Display Board or
the Power Board
depending on the
specific cause of the
failure.
331 POST RF AC
voltage cut feed-
back too high
Monitor senses electrosurgical
voltage output too low during
POST test, indicating insuf-
ficient voltage from HVPS,
insufficient drive from the RF
Controller, failed RF Amplifier,
or a failed voltage sensing chan-
nel. The limits for this com-
parison are set when the system
enters calibration mode.
See 330 above. Confirm proper
connection of J3 on
the Power Board.See
above.
340 Monitor Timer0
interrupt failed
One of the timers internal to
the Monitor is failed.
Cycle system power and deter-
mine if this error is repeated.
Replace the Control/
Display Board.
341 Monitor Timer0
interrupt failed
POST
Failure of one of the timers
internal to the Monitor detected
during POST.
Cycle system power and deter-
mine if this error is repeated.
Replace the Control/
Display Board.
342 Monitor Timer1
interrupt failed
POST
Failure of one of the timers
internal to the Monitor detected
during POST.
Cycle system power and deter-
mine if this error is repeated.
Replace the Control/
Display Board.
343 Monitor has lost
communica-
tions - controller
TOKENS not
incremented
Reset machine and if error
repeats, then replace Control/
Display Board.
Cycle system power and deter-
mine if this error is repeated.
Replace the Control/
Display Board.
