: Tracing defect indicating a missing pattern or frame. Clear the error and ensure the frame is securely inserted .
Locate the connecting cables at the back of the machines. Unplug them and inspect for bent pins or corrosion. Re-seat the cables firmly and tighten any thumbscrews. Power on the tracer first, followed by the edger. Preventative Maintenance to Avoid Future Error Codes
Clean the frame groove; embedded debris can throw the stylus off track.
: Turn the machine off, wait 30 seconds, and turn it back on to clear temporary software glitches. Clear Obstructions essilor kappa error codes
: Typically related to an initialization failure. This can be caused by dirt or oxidation on motor flex cable connectors or a faulty positioning motor.
The machine displays or EEPROM Errors .
Error codes on the Kappa system are typically presented as a letter followed by numbers and a special character. The most common formats found in service reports include: : Tracing defect indicating a missing pattern or frame
The most common cause of errors is residue from lenses causing sensors to fail or gears to stick. Clean the entire chamber thoroughly.
The edger traces the lens shape perfectly, but mid-way through beveling, it "drops" the bevel and skates off the edge.
| Interval | Task | Prevents Error | | :--- | :--- | :--- | | | Clean water tank, check float switch. | E-402 (Water level low) | | Weekly | Inspect clamp pads for wear (replace if <2mm thick). | E-413 (Clamp pressure) | | Bi-Weekly | Apply light oil to linear guide rails (Mobil Vactra #2). | E-201 , E-312 (Motion errors) | | Monthly | Run 3 full dressing cycles. | E-507 (Wheel glazing) | | Quarterly | Calibrate the tracer (use a certified 50mm calibration sphere). | E-722 , E-550 (Size accuracy) | | Annually | Replace pneumatic filter element and regulator diaphragm. | Spurious pneumatic errors. | Unplug them and inspect for bent pins or corrosion
: If the machine produces "Calibration NOK" (Not OK), navigate to the Maintenance and Servicing section to recalibrate feelers or the touch screen. Mechanical Checks :
Fix: This requires a full system power cycle. If the error persists daily, the camera processing board or data ribbon cable inside the chassis is failing to initialize.
: Turn off the main switch on top of the machine, wait 10 seconds, and restart to allow the edger to re-initialize.
