ZEISS SL 130
ZEISS · Model SL 130
With its symmetrically arranged, easy-grip slit projector controls, the SL 130 provides excellent support for laser therapies with the optional VISULINK® 532/U in combination with VISULAS® 532s, as well as for contact glass examinations. System operation is intuitive and highly accurate, enabling precise adjustments of length, width and rotated slit image. And ergonomic advances are also very much in evidence in the form of the ACCENTO® ergo tube, which supports comfortable working positions and prevents neck and back strain. The SL 130 has a choice of parallel or convergent tube to cater to different working preferences.
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.
Optical / illumination fault
MediumSymptoms: Dim, uneven or no illumination; poor or hazy view; slit / filters not working.
Root cause: Bulb / LED at end of life, a power-supply fault, or contaminated optics.
Alignment / positioning-stage fault
MediumSymptoms: Joystick or slide binds, will not hold position, chin-rest / head-rest drive faults.
Root cause: Worn stage bearings / slides or a positioning-drive fault.
Measurement / capture fault
MediumSymptoms: Reading errors (tonometer / autorefractor / lensmeter), no or poor image capture (fundus / OCT), calibration fails.
Root cause: Sensor / camera fault, a calibration issue, or contaminated measurement optics.
Printer / PC / connectivity fault
LowSymptoms: No printout, images / data will not save or transfer.
Root cause: Built-in printer, the PC, or the network / EMR interface.
Motorised table / chin-rest fault (where fitted)
LowSymptoms: Instrument table or chin-rest will not raise / lower.
Root cause: Table / chin-rest actuator or its switch.

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: Dim, uneven or no illumination
- Replace the bulb / LED module with the correct type.
- Check the power supply and rheostat / brightness control.
- Clean the illumination and viewing optics per the manual.
- Confirm the slit, filters and apertures operate.
- Replace the power supply if output is still low.
Symptom: Measurement or capture error
- Run the instrument self-test / calibration.
- Clean the measurement window / objective.
- Verify against a model eye / test target where one exists.
- Confirm patient positioning and fixation.
- Refer the sensor / camera module if calibration will not hold.
