WARNING
Do not modify the main unit of the OS32C. Do not replace or fix any component of the OS32C other than the ones specified in this manual. Doing so may result in a failure of the safety functions.
If there is any damage to the scan window such as a crack, replace it as soon as possible. Otherwise it may result in a failure of the protective mechanism. Take preventive measures when performing replacement work so that dust does not enter the OS32C.
Always detach all cables from the OS32C before replacing the scan window. Otherwise the motor may start rotating, resulting in injuries.
The window replacement procedure must only be performed by qualified personnel in a clean environment at ambient temperature (5 to 35°C) to prevent the internal optical surface from contamination. Make sure the inside and the outside of the replacement window is clean and free from scratch, dust, and finger print.
The calibration procedure must only be performed by qualified personnel. Before performing window calibration of the new scan window, make sure the window is clean and free from scratch, dust, and finger print. The window calibration procedure must be performed at ambient temperature 5 to 35°C. Failure to inspect the window or set the proper environmental condition during window calibration procedure may cause a reduction in the detection capability of the scanner.
Window replacement kit (P.N.: OS32C-WIN-KIT)
Contents of the kit:
- Scan window [Qty. 1]
- Gasket (pre-installed in the window) [Qty. 1]
- Screw for window (M3) [Qty. 4]
- Flat washer [Qty. 4]
Note that you will require a 2mm Allen key.
Window Replacement Procedure
- Remove power from the OS32C. Remove all the cables connected to the OS32C.
- Using a clean cotton cloth, gently wipe off any dirt or dust from the front of the unit that may inadvertently enter the internal space of the OS32C while the window is removed. (Do not use standard compressed shop air to blow off dust from inside the unit)
- Remove the four screws and washers on the sides of the window.
- Remove the existing window by using a small flat-head screwdriver to gently pry up the window’s edge.
- Verify that the gasket is properly seated onto the new window. Gently press around the gasket surface with your thumb. To remove airborne particles from the inside of the unit only use low pressure compressed air that is suitable for optics and sensitive electronics.
- Install the new window. Make sure the arrow on top of the new window points towards the front of the scanner. Care should be taken to ensure that the inside and outside of the window is clean and free of fingerprints.
- While applying even pressure to the top of the window, evenly tighten the four screws with flat washers in an alternating pattern ( Fig. 7-16). It is recommended that the screws be tightened to a torque of 0.56 N•m (5.0 lb-in). Excess pressure on the edges of the window may result in cracking of the material.
- Perform window calibration. After the window is replaced, the scanner may display diagnostic code 50 if window calibration is not performed.
Window Calibration
The window calibration procedure measures the contamination level of the OS32C scan window to reset the threshold values of window transmittance, which serves as a reference for window contamination warning detection. To execute this procedure, the user must log on with the supervisor access level.
- From Utilities menu, select Window Calibration.
- A screen shown below is displayed. Click OK to confirm.
- When window calibration starts, the window shown below is displayed.
- When calibration is successfully completed, the window shown below is displayed. Click Save to confirm.
- Confirm that the window calibration data has changed, and wait for the OS32C to reset. Calibration is complete.
Note: The window shown below may be displayed even after replacing the scan window, due to dust or finger prints on the scan window or dust detection surface during replacement. Clean the inside and outside if the scan window and surface of the dust detection surface using a soft cloth.
