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.
