Richard Wolf Logic HD
Richard Wolf · Model Logic HD
HDR - High Dynamic Range describes exploitation of the full dynamic range of image material. Dark image areas are lightened and very bright, over-exposed areas are darkened. Color Contrast Modi 1 bis 3 - The Color Contrast Modes strengthen color contrasts incrementally and use preset color shifts in order to highlight these enhanced areas even further. Adaptation - ENDOCAM Logic HD has a large number of application profiles that have been tested in clinical settings and can be quickly selected. Integrated documentation - ENDOCAM Logic HD can record Full HD videos on a USB storage. Also integrated is a still image archive, printing function and patient data input mask.
Key tips
- ·A failed leak test means the scope does not get reprocessed or used - send it for repair, full stop.
- ·A shortened reprocessing cycle is a real infection-control failure, not a minor deviation - follow AAMI ST91 exactly.
- ·Track light-source lamp-hours against the manufacturer's limit rather than running to failure.
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 dim illumination / lamp fault
HighSymptoms: No light output, dim or flickering light, lamp-hours alarm, colour shift.
Root cause: Xenon / LED lamp at end of life, a lamp power supply fault, or a light-cable fault.
Poor video image
HighSymptoms: Noisy, dark, discoloured or out-of-focus image, dropouts, no image.
Root cause: Camera head / coupler fault, a camera-cable fault, or a CCU / video-processor fault.
White-balance / colour fault
MediumSymptoms: Cannot white-balance, persistent colour cast.
Root cause: Camera head sensor drift, a dirty coupler, or the light source colour temperature.
Overheating / fan fault
LowSymptoms: Thermal shutdown, loud fan, hot exhaust.
Root cause: Failed or clogged cooling fan.
Output / connector fault
LowSymptoms: Signal only on one output, connector damage, HD/SDI dropout.
Root cause: Worn video output connector or an output board 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.
- ·Leak testing before each reprocessing cycle
- ·Scope reprocessing per AAMI ST91
- ·Light source lamp-hour tracking
- ·Annual 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 poor video image / recording will not start / files corrupt
- Confirm a valid input signal on each source (SDI / HDMI / DVI / composite).
- Swap the input cable and try another input.
- Clean the scope lens / coupler and re-white-balance (endoscopy camera).
- Swap the camera head and cable to isolate head from CCU.
- Replace the camera head or the capture board as isolated.
Symptom: Storage / media fault / export fails
- Check free space and the internal drive health.
- Test export to USB and to the network share separately.
- Confirm the PACS / share settings and credentials.
- Replace a failing internal or optical drive.
- Verify an exported study opens on another workstation.
Symptom: Capture will not trigger / footswitch or camera-button fault
- Test the footswitch and its cable.
- Test the camera-head buttons.
- Check the trigger input configuration.
- Replace the footswitch or trigger cable.
- Confirm capture from each trigger source.
