ERBE APC 3
ERBE · Model APC 3
Plug and Operate - less setting adjustments or modifications Select Up to 2 Sub-Programs - toggle between electrosurgical function and argon plasma coagulation based on your technique pulsedAPC and forcedAPC finely adjustable with 100-step effect setting preciseAPC, the new mode for the lower power range and sensitive structures.
Key tips
- ·Never defeat or bypass a return-electrode monitoring (REM) alarm to finish a case - it's a direct burn risk.
- ·Verify OR table battery backup - a table that loses power mid-procedure is a real, documented incident type.
- ·Track surgical light lamp-hours rather than waiting for failure - a sudden failure mid-case is avoidable.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
No or low RF output / high-impedance cut-out
HighSymptoms: No cut / coag effect, "high impedance" or output-error message, output shuts down.
Root cause: Poor electrode contact or a dry field, a damaged handpiece / cable, a return-electrode (REM/NESSY) fault, or an output-stage fault.
Return-electrode (patient-plate) contact-quality alarm
MediumSymptoms: REM / NESSY / plate alarm, monopolar output inhibited.
Root cause: Poorly applied or dried split dispersive pad, a pad-cable fault, or the contact-quality-monitor circuit.
Argon flow / plasma-ignition fault
MediumSymptoms: Argon does not flow, plasma will not ignite, gas-supply or APC-probe alarm.
Root cause: Empty / low argon supply, a flow-control valve fault, or an APC-probe / connector fault.
Fails calibration / output drifts after a repair
MediumSymptoms: Output power or the REM circuit outside tolerance on the analyser.
Root cause: Output board or REM circuit needs recalibration - anti-static handling required.
Footswitch / handswitch fault
MediumSymptoms: Output will not activate from the pedal or the handpiece.
Root cause: Footswitch or handswitch / cable fault.
Touchscreen / display / boot fault
LowSymptoms: Unresponsive touchscreen, will not power on or boot, fan / thermal alarm.
Root cause: Display, power supply, control board, or a cooling-fan fault.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Pre-case functional check
- ·Electrosurgical return-electrode cable inspection
- ·Table hydraulic / mechanical inspection
- ·Annual electrical safety test and full PM
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: No or low RF output / high impedance
- Confirm good electrode-tissue contact and an adequately wetted field.
- Inspect the handpiece / instrument and cable for damage; substitute known-good.
- Check the split dispersive pad is well applied with full skin contact and a good cable.
- Verify output into a resistive test load with an electrosurgical analyser.
- Replace the output board and recalibrate if output is confirmed absent (anti-static workplace).
Symptom: Return-electrode / plate alarm
- Re-apply a fresh split dispersive pad with full skin contact over well-perfused muscle.
- Check the pad cable and connector.
- Try a known-good pad.
- Run the contact-quality-monitor calibration if it still alarms with a good pad.
- Do calibration on a non-conductive surface.
