Action
• Be sure the generator is plugged into a
working electrical outlet.
• Check power switch on back of
generator.
• Unplug and check the fuse on the rear
panel. Fuses should only be replaced
with LittelFuse 2183.15, Time Delay (Slo
Blo) rated at 3.15A, 250VAC.
• Check connections to coagulation device
and indifferent, dispersive electrode.
• Ensure device is properly placed on
tissue site.
• Check position of indifferent, dispersive
electrode on patient's back or thigh.
• If problem persists, replace the
coagulation device and indifferent,
dispersive electrode.
• Power unit OFF, then Power ON again.
• Allow generator to run through normal
start-up self-diagnostics.
• If generator returns to Error state and the
problem persists, contact your AtriCure,
Inc. representative.
• Depress and release the indicated button
to determine if the button remains stuck.
• Power unit OFF, then Power ON again.
• Allow generator to run through normal
start-up self-diagnostics.
• If generator returns to Error state and the
problem persists, contact your AtriCure,
Inc. representative.
• Verify the footswitch is connected to the
front panel of the generator
• Ensure Time is not set to 0.
• Ensure IMP LIMIT error is not detected -
impedance should be within 30 – 500Ω.
• Ensure a coagulation device is connected
to the generator
• Ensure the indifferent, dispersive
electrode is attached to the patient and
connected to the generator
• Check the footswitch by unplugging its
cable from the generator, placing a
thumb over the foot pedal connector then
depressing the pedal. If the footswitch is
functioning properly, air should be
expelled through the connector as the
footswitch is depressed.
• Ensure the cables from the electrodes do
not cross the cables from the ultrasound
probe or other equipment.
• Changing settings on the ultrasound may
alleviate image interference.
Symptom
Impedance is greater than 500 Ω
at the beginning of RF power
delivery
Impedance is less than 30 Ω at
the beginning of RF power
delivery
LBL-2123 Rev. F
Action
• Ensure the indifferent, dispersive
electrode is properly attached.
• Check all connections.
• Clean off any coagulum from the
coagulation device.
• Ensure device is properly placed on
tissue site.
• Reposition the coagulating device
