Berchtold OPERON D 820
Berchtold · Model OPERON D 820
1000 lbs of lift through full range of articulation including table top slide Superior positioning of bariatric patients with consistent weight capacity Range of motion from 25 to 42.3 Accommodates standing or seated position for the surgeon Nearly 17 of longitudinal slide Maximum tilt of +/- 20º and Trendelenburg/Rev of 30 º.
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.
A powered function will not run
HighSymptoms: Height, tilt, Trendelenburg, back or leg section does not respond to the hand control / pendant.
Root cause: Hand control fault, an electro-hydraulic actuator, a control-board fault, or a low battery (mobile column).
Section drifts or will not hold
MediumSymptoms: Table settles under load after positioning.
Root cause: Hydraulic valve internal leak or an actuator backdrive.
Battery will not hold charge (mobile column)
MediumSymptoms: Short run time, table dies mid-procedure, battery alarm.
Root cause: Aged battery pack or a charger fault.
Hand control / pendant / cable fault
MediumSymptoms: Intermittent or dead hand control.
Root cause: Worn hand control or a damaged cable.
Table-top segment / rail / pad fault
LowSymptoms: Segments loose, accessory rails will not clamp, pads torn, radiolucent top damaged.
Root cause: Worn segment latches, rail clamps, or upholstery.

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: A powered movement will not run (height / tilt / Trendelenburg / back / leg)
- Confirm the table is on mains or the mobile-column battery is charged, and no lock-out is set.
- Operate the function and listen for the electro-hydraulic pump / actuator.
- Substitute a known-good hand control / pendant.
- Check the control cable and connectors for damage.
- Replace the actuator, the hydraulic valve or the control board as isolated, then load-test.
Symptom: A section drifts down / will not hold position under load
- Note how fast it settles and under what load.
- Check the hydraulic control valve for internal leak-by and the actuator for backdrive.
- Bleed and top up the hydraulic system per the manual.
- Rebuild or replace the leaking valve / actuator.
- Confirm the section holds at several positions under the rated load.
Symptom: Battery will not hold charge (mobile column)
- Charge fully and check the charger.
- Run a battery test if supported.
- Replace the battery pack.
- Confirm a full set of movements on battery after replacement.
- Inspect the charge socket and cable.
Symptom: Hand control / pendant intermittent or dead
- Flex the cable along its length and at both ends while operating.
- Inspect the connector for bent pins or moisture.
- Substitute a known-good pendant.
- Replace the pendant or its cable.
- Confirm every function from the replacement.
