7-4 SurgiStat Low-Power Electrosurgical Generator Service Manual
Understanding Error Codes and Audio Tones
If the return electrode receptacle on the front of the generator is damaged, contact
your Covidien Service Center.
Inspecting Internal Components
To inspect internal components, follow this procedure.
1. Remove the four screws that secure the cover to the chassis.
2. Lift the cover from the chassis. Set the cover and screws aside for reinstallation.
3. Visually inspect and verify all connectors are firmly seated.
4. Inspect each board for damaged components, wires, cracks, and corrosion.
5. Reinstall the cover by positioning the cover over the chassis. Secure with the original
screws.
Understanding Error Codes and Audio Tones
The SurgiStat generator includes automatic, continual self-diagnostics. If the diagnostics
detect an error, the system displays an error code, sounds an audible tone, and deactivates
the output power.
Any errors detected will shut down the RF output power.
Most error codes result from faults in accessories attached to the generator. The following
table lists the error codes, describes the error, and recommends actions to take to resolve
the error
Precaution
The generator contains electrostatic-sensitive (ESS) components. When repairing the generator,
work at a static-control workstation.
Wear a grounding strap when handling electrostatic-sensitive components.
Handle circuit boards by their nonconductive edges.
Use an anti-static container for transport of electrostatic-sensitive components and circuit boards.
Notice
Internal firmware self-diagnostics continually monitor generator operation to ensure proper and
safe performance.
