339
Calibration RF AC
voltage coag feed-
back too low
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.
See above.
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
Controller assembly.
341
Monitor Timer0
interrupt failed
POST
Failure of one of the tim-
ers internal to the Monitor
detected during POST.
Cycle system power and deter-
mine if this error is repeated.
Replace the
Controller assembly.
342
Monitor Timer1
interrupt failed
POST
Failure of one of the tim-
ers internal to the Monitor
detected during POST.
Cycle system power and deter-
mine if this error is repeated.
Replace the
Controller assembly.
343
Monitor has lost
communica-
tions - controller
TOKENS not
incremented
Reset machine and if
error repeats, then replace
Controller Assembly or
replace U9.
Cycle system power and deter-
mine if this error is repeated.
Replace the
Controller assembly.
344
Monitor Isense
DMA or SPI hung
The Monitor DMA or
SPI interface to one of the
ADCs has failed.
Cycle system power and deter-
mine if this error is repeated.
Replace the
Controller assembly.
345
Monitor Power
DMA or SPI hung
The Monitor DMA or
SPI interface to one of the
ADCs has failed.
Cycle system power and deter-
mine if this error is repeated.
Replace the
Controller assembly.
350
Monitor output
channel current
sensor failure
Current detected by the
monitor through the output
channel current sensor that
is used to detect a stuck out-
put relay does not match the
current sensed by the power
monitoring sensor.
This typically indicates that
there is a problem with the
output channel current sens-
ing 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 RF Amplifier.
Repair or Replace
the RF Transformer
board.
Repair or Replace
the RF output
board.
Replace the
Controller assembly.
351
Monitor sensed
over power condi-
tion for 300mS
running average
Over power at the
electrosurgical output has
persisted 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 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 cir-
cuits, the HVPS, and the RF
Amplifier.
Repair or Replace
the HVPS.
Repair or Replace
the RF Amplifier.
Repair or Replace
the RF Transformer
board.
Repair or Replace
the RF output
board.
Replace the
Controller assembly.
