Elmed ESU 120
Elmed · Model ESU 120
THREE DISTINCTIVE RADIO FREQUENCY OUTPUT MODES WITH AUTOMATIC OUTPUT COMPENSATION IN ALL MODES • Mode I (Macro Output..Pure cutting power by means of non modulated RF-current and blended power by modulated RF-current for cutting and coagulation • Mode II (Micro Output RFTA).. Timed by the automatic timing circuit, low power level up to 10 W radio frequency current at a low voltage that generates low tissue temperaturespecifically for Radio Frequency Thermal Ablation (uvulopalatoplasty andtongue base reduction) • Mode III Bipolar non-modulated current for general bipolar surgical procedures and bipolar submucosal turbinate surgery according to Dr. Dennis • DIGITAL READOUT Each mode has an independent digital wattage readout, as does the timing circuit for Radio Frequency Thermal Ablation. • SAFETY CIRCUIT Automatic sensing device cuts off the output if the indifferent patient circuit is defective, and gives visual and audible alarm.Reusable or disposable electrodes may be used.Optional Return Electrode Monitor (REM) may be installed at extra cost. The operation of the ELMED ESU 120 M/M DIGITAL with SMART-O-MATIC is extremely easy. The generator is activated by means of a single pedal footswitch. • SMART-O-MATIC CIRCUIT Our automatic output compensation circuit provides the desired output for all electrodes or tissue conditions.The automatic range control requires no readjustment within the set range. • AUTOMATIC TIMING CIRCUIT The automatic timing circuit is triggered by the footswitch.The time can be selected between 1-10 seconds and is shown on the digital display and it will cut off the current flow as the time has expired, or when the surgeon removes his/her foot from the footswitch. It is reactivated to the same preset specifications by depressing the footswitch.
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
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Return electrode / pad fault
HighSymptoms: Pad alarm, no activation.
Root cause: Poor contact or expired pad.
Foot switch failure
MediumSymptoms: Unintended or no activation.
Root cause: Fluid ingress / worn switch.
Table hydraulic / actuator fault
MediumSymptoms: Slow or drifting positioning.
Root cause: Cylinder seal or actuator wear.
OR light LED failure
LowSymptoms: Dim or dead panel, color shift.
Root cause: LED module aging.

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 structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Electrosurgical electrode wear
- Confirm the presentation - typically poor cut/coag, sparking, low power - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: burned/eroded blade or pencil.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the electrosurgical pencil & electrode per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
