Technical and Electrical Safety Check

2.2.1 General Information The detailed description of the technical safety check procedure can be found in Service Bulletin 400. This Bulletin is for all Carl Zeiss Meditec AG medical products applicable and equates the latest international rules for electrical safety. Additionally, this service manual also describes the most important procedures inclusive the instrument-depending varieties, e.g. the reading points for the different tests. Note If you have national rules for electrical safety, SB 400 is in force only analogous. In this case you have to fulfil the values of your national standards (e.g. NFPA 99, AAMI ES-1). Only qualified technicians shall perform these tests. Qualification shall include training on the subject, knowledge, experience, and acquaintance with the relevant technologies and regulations. The technician shall be able to assess safety and shall be able to recognize possible consequences and hazards arising from non-conforming equipment.

2.2.2 Procedure of the technical safety check Complete the following points in line with the test procedures of the Instrument Checklist: • • •

Check that the housing (in particular the ventilation slots) is undamaged and free from contamination. Check all cables (in particular the insulation) for damage. Check that all notes and labels are complete and correctly positioned using the user manual.

Checking the electrical safety (This test must be performed as part of the start-up procedure, the annual maintenance service and technical safety check, or after repairs affecting safety-relevant components). During the technical safety check, the device must be tested for electrical safety. Perform the measurements in accordance with IEC 62353:2007 and DIN EN 62353:2008. − The measuring results must be documented in the technical safety check report (See SB 400)

IOLMaster 5.5

Procedure: 1. Measuring protective ground resistance • A maximum test voltage of 24V and a test current of 10A AC are recommended for measurement. • Connect the device with its connecting cable to the power socket of the safety tester (e.g. RIGEL 288). • Firmly press the test probe against a screw head on the housing of the IOLMaster (see Figure 2 – 1) • Start the measurement and note down the measured value. • If the IOLMaster is powered via the power socket of the IT table, repeat the measurement for the table. The same applies if the system is operated via a multiple socket. Include the multiple socket into the measurement in this case. • Note down the highest value measured. • The limit value that must not be exceeded is 0.3 Ohms for devices with a power cord and 0.5 Ohms for systems with a multiple socket. 2. Measuring the leakage current • We recommend using the differential current method, where the device is measured during operation and both phase directions are taken into account. The IOLMaster connected and operated via the safety tester. • When using the RIGEL 288 tester, select IEC 62353, differential measurement and semi automatic mode (to boot and shut down the computer manually during reversal of polarity). • Please note the risk of a computer damage using safety testers with fully automatic reversal of polarity! • Switch on the instrument at the main switch. • Firmly press the test probe against a screw head on the housing of the IOLMaster (see Figure 2 – 1 and Figure 2 – 2) and start measurement. The tester automatically performs a reversal of polarity. • Note down the highest value measured. • The limit value of 0.5 mA must not be exceeded in any of the measurements. 3. Measuring the insulation resistance • Perform this measurement at 500V DC. • Connect the power cord of the IOLMaster to the power socket of the safety tester. • Switch on the instrument at the main switch. • Start the measurement. • Note down the measured value. • The measured value must not be less than the limit value of 1 MOhm. • If the IOLMaster is operated via the power socket of the instrument table and/or via a multiple socket, repeat the measurements accordingly.

3.1.9 CCD Camera Spare part:

1770-340

CCD camera set, 9V

Note: The (redesigned) alignment device for IOLMaster is absolutely vital for replacing the CCD camera. Without this tool it is impossible to verify the required focus level of the camera. This may lead to incorrect measurement, especially with regard to ACD measurements. Alignment issues between the overview and Keratometry positions may also present themselves. The exchange of the CCD camera without using the (redesigned) alignment device is not permitted. Old alignment devices (bought before July 2008) can be retrofitted. Please send the related tools to our Jena (Germany) repair center.

IOLMaster 5.5

Identifying a “worn out” CCD camera Note: Before determining whether a camera is “worn out”, several preconditions must be checked and / or set on an IOLMaster to ensure that the camera parameters are properly adjusted. 1) Preconditions: ƒ Proper connections ƒ Frame grabber settings (see 4.1.3) ƒ Clean optics (see 4.2.1) ƒ Camera sensitivity voltage settings (see 4.2.6) ƒ Surrounding field illumination settings (see 4.2.7) ƒ Aperture alignment (see 4.2.12) 2) Signs for a worn out CCD Camera ƒ Most easily noticed in the Overview mode, a black strip will be seen along the left edge of the Fig. 3 – 8: Frame Grabber settings camera image. This black strip will encompass the full height of the camera image, and will widen with time. Fig. 3 - 9 shows a typical black strip. ƒ When in the Overview mode or/and Keratometer mode the illumination and fixation markers will have a black shadow to the side. In extreme cases the shadows will appear as bars that trail to the side as indicated in Fig. 3 - 9.

Checklist before replacement Black stripe at the left edge

Note: The following points are vital to be checked as “YES” to ensure a successful camera replacement.

Black shadows/trails beside the illumination and fixation lights

Fig. 3 – 9: Worn out camera

1) Camera alignment tool (See 5.3 – tool list) available? 2) Live-image visible? Note: Heating up a CCD camera which does not show any image can easily re-activate it. Use a heat gun for this purpose. Be extremely carefully while blowing hot air into the instrument. There is a high risk of damaging other components. 3) CCD camera is still in the original position (compare crosshair position between Overview and Keratometer mode with the test-eye) and measurements (ALM) show good results in relation to the SNR value?

Parts Removal / Replacement

Note: If the CCD camera is no longer in its original position and / or the SNR of the ALM measurements is not within specification, the replacement of the camera must be aborted, and the measurement head must be sent in for repair in house. Removal: Note: The following procedure describes only the replacement of the CCD camera. The positioning will only be as good as the old / worn-out camera was. It is not possible to re-align the camera if once the original position has been lost or if the present camera is misaligned. This requires either a head-replacement or in-house repair. 1) Remove both head covers – see 3.1.1

1

2) Remove the test-eye from the chin rest, if present. 3) Attach the alignment tool to the Keratometer. Position the tool 30° tilted from the axis and center the ring to the hole of the Keratometer. Rotate the tool until the hooks are behind the Keratometer frame and tighten the screws carefully. Check that the tool is immovable. 4) If not already done, switch on the IOLMaster, create a test patient and change to the Keratometer mode. The sphere side of the rotatable head must be in the direction to the instrument.

5) Focus the spots (using the Z-drive screw of the tool) and align the X and Y axis in relation to the crosshair. Loosen the knurledhead screw to position the sphere. Tighten the screw when done. Note: The image in Keratometer mode must be exactly centered as shown below before proceeding further.

Fig. 3 – 10: Aligning the tool

6) Cut off all cable ties (zip ties) from the monitor and control cable. Remove screws from any cable clamps which may be present. Loosen the two screws (4 mm hex key) which hold the LCD in place, and carefully lay the LCD next to the instrument. Exercize caution so as not to stretch the cable. Note: Observe ESD protection measures when working on electronic components. 7) Shut down the instrument and disconnect the camera cable from Digital IOL PCB (X219) 8) Remove the four screws (2 mm hex key) and replace the CCD camera SM-30-4054-en Section 3, Revision A, Feb. 2010

9) Loosely secure it with the four screws (2 mm hex key) and plug-in the camera cable (X219) 10) Adjust the camera sensitivity voltage as necessary (2.9 ± 0.3V at R75, next to X219) and align the camera to the tool (in Keratometer mode). Remember that the image on the screen must be exactly centered. Be as accurate as possible while aligning the camera. 11) Check overview and Keratometer position by moving the magnification changer manually in PIOTest (motor-tab). If the CCD camera was well positioned, both crosshairs should match with the sphere (no horizontal / vertical gap). Focus shift determination / compensation 1) Rotate the tool-head 180° (“black-finished” back-side must face to the instrument). 2) Change to Keratometer mode and run PIO-Test (service-mode). Go to “Chanel 3” of the PIO-Ports tab and switch on the slit groups alternately.

Fig. 3 – 12: Focus shift

3) By turning the Z-axis screw of the tool, the background of the tool-head can be focused. If the focus level of the CCD camera matches to the optical alignment of the instruments, both slits are projected to the middle of the crosshair and do not “virtually” move while switching on the left and right hand side of the slit groups alternately. As a tolerance range, the inner circle of the crosshair can bee seen. While focused, the slit projections must lie within this (inner) circle. 4) If there is a focus shift present, the slits are not projected as described in Fig 3 - 12 - they are out of the middle position while the background is focused – see Fig. 3 - 13

5) See the Fig. 3 - 14 and 3 - 15 to determine if the focus level of the CCD camera is too far in the front or too far in the back. 6) If the left slit is projected too far left and the right slit projected too far right, the focus level of the CCD chip is too far back – add shims between the white camera bases and the metal plate.

Fig. 3 – 14: Focus shift – CCD chip too far back

7) If the left slit is projected too far right and the right slit projected too far left, the focus level of the CCD chip is too far in the front – add shims between the casting and the metal plate of the camera.

Fig. 3 – 15: Focus shift – CCD chip too far in the front

Note: Adding shims will require you to take the camera out again. Follow the related sections of the replacement procedure. Afterwards continue to determine the focus shift again. Note: Always add equal numbers of shims to all four fixation points – either one shim (0.2 mm) or two shims (0.4 mm) at each point. 8) Continue as long as the focus shift meets the tolerance range (While the background is focused, the slit projections must lie within the inner circle of the crosshair). Reassembly: Reassemble in reverse order observing the following instructions. 1) Reassemble the instrument in reverse order. Secure the LCD cable loop safely using zip ties. Ensure free movement for the changer. Remove the tool and reattach the head covers. Quit PIOtest and service mode 2) Take measurements with the test-eye and verify the calibration. Re-calibrate KER and ACD if needed.-see 4.4.3 and 4.4.2 3) Compare SNR values (ALM measurements) of “before” and “after” the camera replacement, values should be equal. 4) Perform a System Checkout in accordance with the instrument checklist.

4.1.4 Prog Tab The Prog Tab provides the “Save” section, the “Output” section and the “Database” section. The defaults are shown in Fig. 4 - 6. “Save” section The “Grab Images” checkbox can be activated to highlight the checkboxes next to it. These checkboxes can be individual activated to save the images during the measurement (KER, ACD or WTW). The related images will be saved in the IOLMaster folder and may be used later for detailed troubleshooting

Fig. 4 - 6: Prog Tab

Note: After the images have been made, the feature must be deactivated manually again. Otherwise, the speed of the measurements will slow down and the HDD will be overloaded with images. “Output” section Activating the “Detailed Output” checkbox will show the detailed measurement of the KER. Instead of an average measurement, the five individual results will be displayed. “Manual R/L Switch” allows switching via touchpad between the left and right eye side, without moving the instruments head. The magnetic sensor which normally detects the right and left side is temporary disabled. To switch between both sides, just click in the related column (OD or OS). “Save and show Raw Signal” is only used at the factory. It shows the raw signal in ALM mode. “Database” section With both of these checkboxes checked, older patient files will be deleted from the HDD after the time specified in “Program Settings” menu has elapsed. Unchecking these boxes should not be done, as this would allow the HDD to fill up.

4.1.5 System Tab The system tab page provides links to the Windows® Explorer, the Control Panel, the PIO-Test, the Speed Test and the EEPROM. It is also possible to erase some data via the “Delete Data” link

4.1.8 Read / Write EEPROM The EEPROM is the main location of all calibration data. There is also a backup file for this data, which can be found in the IOLMaster folder. The name of the file is “iol.ini”. “Write INI File” This option will manually create a backup file (ini-file). The destination can be chosen within a popup-window. Please note that the destination must be entered by hand (in the “File name” field) and can not be selected by browsing folders. Note: The changer steps will also be written into the *.ini-file. Fig. 4 - 10: EEPROM

“Read INI File” This option reads an existing ini-file. The destination can be chosen within a popup-window. Please note that the destination must be entered by hand and can not be selected by browsing folders. “Write to EEPROM” This option re-writes the EEPROM with the data currently displayed in the sections of the EEPROMscreen (see Fig. 4 - 10). The instrument must be restarted after the EEPROM has been rewritten. It is highly recommended to compare the data of the ini-file and the EEPROM afterwards to verify the success of the writing procedure. Open the related ini-file via “Notepad” and compare the sections with those of the EEPROM screen. If they are not the same, repeat the procedure.

4.1.9 PIO-Test The PIO Test contains three tabs which can be used for field-service. The “Inbetriebnahmetest” tab is only for the manufacturing. For efficient use of the PIO-Test, the service-mode must be closed. Therefore click outside of the PIOTest window to get back to the main service mode. Exit the service mode and get back to the PIOTest window by using the + key-combination on the keyboard.

4) Mark an individual measurement (not the composite measurement) from the active column of measurements and move the white spot manually over the left end of the red graph using the right mouse button. 5) Mark another individual measurement (not the composite measurement) from the active column of measurements and move the white spot manually over the right end of the red graph using the right mouse button. Note: Do not use the left mouse button because the left button will automatically determine any peak in the area of positioning the white spot. In that case you may not be at the end of the measurement range!

Fig. 4 - 39: Measurement range (upper)

Note: Sometimes, if the white spot extends past the end of the range, instead a logical value (e.g. 13.92 mm), a dash “-“ which symbolizes an “error” or a high numeric value appears. In this case the spot is out of the available range. Slightly move the spot (using the right mouse button) in direction to the inside of the measurement range until an mm-value appears. 6) If needed, adjust the measurement range to ≤ 13.5 mm and ≥ 38.5 mm (lower than 13.5 mm and greater than 38.5 mm). It is not needed to widen the range much more than that. In the case of the lower end (13.5 mm) can’t be reached, you have to adjust the lower sensor (edge detector) of the interferometer - you have to move it upwards.

Sensor Note: The Flag alignment primarily changes the measurement-position. The overview-position will also be affected by this alignment and must be re-aligned afterwards. The sensor must be adjusted according to the following criteria: ƒ the position according the optical path (rough positioning) and ƒ the position in relation to the changer motor phase (fine positioning) Procedure: 1) Remove both head covers – see 3.1.1. 2) Cover the optical path, to avoid any light interference. 3) Position the Test Eye (ALM Sphere) in front of the instrument. 4) Switch on the instrument, choose the “Check, Device” patient or activate the Test Eye function and select ALM mode. Position the measurement head according the sphere. Run PIO-Test (service-mode). Go to “Chanel 2” of the PIO-Ports tab and switch on the laser (100%). Caution: Do not operate the laser diode at "100% Power" for more than 5 minutes.

5) Change back to ALM mode (click outside the PIO-Test) and position the measurement head in a way, that both, the bright laser spot (primary reflection) and the secondary reflection (see Fig. 4 - 47) are over each other and fix the position of the measurement head. Note: If this position is not roughly aligned with the crosshair, this can be taken as prove that the sensor of the magnification changer must be aligned. 6) Switch between measurement-position and overview-position back and forward. At the moment check only the measurement position. If the position where both laser reflexes lie over each other don’t match with the crosshair position, the sensor must be re-aligned. 7) Loosen the sensor (two screws) and change the position slightly. Depending if the crosshair stays left or right from the laser spot, the sensor must be aligned to the left or right hand side. Note: Whatever will be done at the sensor, do not move the position of the measurement head. It is of vital importance the measurement head keeps positioned as the laser reflections stay over each other.

Note: You are now in KER mode and should see the spots and the crosshair perfectly aligned. If not, manually move the changer once again (click the checkbox next to “Changer”) to overview- and back to measurement position. If necessary also re-position the head. 10) Click “Step +” several times (at least 8 times). The motor will move the optics (image) now to the left hand side (out of the crosshair). 11) Click “Step –“ until the “End” position switches from 1 to 0 (indicates that the sensor has detected the flag). Continue pressing “Step –“until the “phase” shows 00 and count the number of motor-steps in between of the switch of the end-position and the 00 (The switch itself from 1 to 0 does not count). 12) The accepted range for this “switch-gap” is 2 or 3 steps. Any other number requires a fine adjustment of the sensor position. Loosen the sensor again and slightly move it. Be carefully, the necessary alignment requires a minor positioning only. Note: The fine adjustment may take some time and some attempts. Be accurate with this alignment, because it will ensure the stable positioning of the measurement lens. Remember: All measurements taken by the instrument are related to this positioning! 13) Use the manual control of the changer (PIO-Test / Motor tab) to switch between the measurement-position and overview-position and back to see the effect of the sensor-alignment. Always check the alignment according the laser spots before checking the fine-alignment according the steps (switch-gap). 14) If the sensor is successfully aligned, finally tighten the screws.

Loosen the screws and move the flag to the left. If the “end position” indicates 0, skip to section 9. 8) Move the changer manually to the measurement-position and back to overview to see the effect of the alignment. Use again “Step +“/ “Step –“to manual position the crosshair according the image. If still the “end position” shows 1, the flag must be adjusted again. 9) Now click “Step –” several times (at least 8 times). The motor will move the optics (image) now to the right hand side (out of the crosshair). The “end position” should switch from 0 to 1 somewhere in between. 10) Now, click “Step +“as long as the “end position” switches from 1 to 0 (indicates that the sensor has detected the [adjustable] flag).
