Description Possible Cause Things to check Correction
350 Monitor output
channel current
sensor failure
Current detected through the
output channel current sensor
that is used to detect a stuck
output relay does not match
the current sensed by the
power monitoring sensor. This
typically indicates that there is a
problem with the output chan-
nel current sensing circuit.
Configure the system for test
mode operation and cycle power.
Use DACview to compare the
output channel current with the
output current while activating at
constant power into a fixed load.
Repair or Replace
the Power board.
Replace the Control/
Display Board.
351 Monitor sensed
over power
condition for
300mS running
average
Over power at the
electrosurgical output has per-
sisted for more than 300 ms.
Configure the system for test
mode operation and cycle power.
Measure the actual power into
a fixed load. If power is cor-
rect, verify proper operation of
the Monitor voltage and cur-
rent sensing circuits. If power is
correct, verify proper operation
of the RF Controller voltage
and current sensing circuits, the
HVPS, and the RF Amplifier.
Repair or Replace
the Power board.
Replace the Control/
Display Board.
357 Monitor sensed
power @ 0W
dial power set-
ting
The Monitor has sensed
electrosurgical output power
during activation while the
power is set to zero.
Recalibrate the system. Configure
the system for test mode opera-
tion and cycle power. Measure
the actual power into a fixed
load. If power is correct, verify
proper operation of the Monitor
voltage and current sensing
circuits. If power is correct,
verify proper operation of the RF
Controller voltage and current
sensing circuits, the HVPS, and
the RF Amplifier.
Repair or Replace
the Power board.
Replace the Control/
Display Board.
358 Monitor sensed
gate drive in
idle @ 0W dial
power setting
The Monitor has detected a
drive signal while the system is
not activated.
Cycle system power and deter-
mine if this error is repeated.
Replace the Control/
Display Board.
360 Monitor pro-
gram counter
landed on an
unused interrupt
vector
Monitor processor anomaly. Cycle system power and deter-
mine if this error is repeated.
Replace the Control/
Display Board.
371 Monitor will
not disable RF
waveform on the
Control/Display
Board during
POST
POST has determined that the
Monitor cannot disable the RF
waveform.
Cycle system power and deter-
mine if this error is repeated.
Replace the Control/
Display Board.
375 Monitor activa-
tion I/O failed
POST
POST has determined that acti-
vation commands sensed by the
System Controller do not match
the activation commands sensed
by the Monitor.
Cycle system power and deter-
mine if this error is repeated.
Replace the Control/
Display Board.
