113
Pre-activation
handshake, moni-
tor does not read a
tone signal
Prior to enabling
electrosurgical output
power, the Monitor ensures
that an activation tone is
present. This error occurs
if the activation tone is not
present when the Monitor
checks prior to enabling
electrosurgical output
power.
Increase the tone volume by
adjusting the Volume Control on
the back panel of the generator.
Cycle system power and deter-
mine if this error is repeated.
Configure system for test mode
operation.
Check the tone drive signal from
the Controller assembly while
the unit is activated. Lack of a
signal indicates a problem with
the Controller assembly.
Check for a proper TONE_
MON signal to the control-
ler. Lack of a signal indicates
a problem with the Back Panel
assembly.
Replace the
Controller assembly.
Replace the Back
Panel assembly.
114
Display or key-
board SPI commu-
nication failure
Communication between
the Control assembly and
the Display assembly over
the SPI bus is faulty.
Cycle system power and deter-
mine if this error is repeated.
Check SPI_SCK, SPI_MOSI,
and SPI_MISO to see signals
toggle.
Replace the cable
between the Display
and the Controller.
Replace the
Controller assembly.
Replace the Display
assembly.
117
5.0 volt too low
5-volt power in the system
is too low.
Check the output of the low
voltage power supply.
Verify that the ADC reference
voltages on the Controller are
2.5 volts.
If the power sup-
ply voltage is out of
limits, replace the
power supply.
If the power sup-
ply is within lim-
its, replace the
Controller assembly.
118
5.0 volt too high
5-volt power in the system
is too high.
Check the output of the low
voltage power supply.
Verify that the ADC reference
voltages on the Controller are
2.5 volts.
If the power sup-
ply voltage is out of
limits, replace the
power supply.
If the power sup-
ply is within lim-
its, replace the
Controller assembly.
122
System Controller
flash program CRC
does not match the
calculated CRC
The self-check CRC for the
System Controller is not
internally consistent, indicat-
ing an error in the stored
software.
Cycle system power and deter-
mine if this error is repeated.
Replace the
Controller assembly.
135
A.R.M.™ calibra-
tion (10/150 Ohm)
EEprom CRC
failed
The CRC for the calibration
coefficient memory is not
self consistent, indicating an
error in the stored calibra-
tion coefficients.
Recalibrate the A.R.M.™ system.
See section 4.7.
Replace the
Controller assembly
if the system will not
calibrate.
