+ | ====== Leica Stereo Zoom MZFL III Automated Zoom & Automated Filter Turret Drive Installation Procedure ====== | ||
+ | {{ :: | ||
+ | |||
+ | |||
+ | The procedure below outlines the steps necessary to install the Automated Zoom & Filter Turret Drive onto the Leica Stereo Zoom microscope. | ||
+ | |||
+ | == To perform the following steps you will need the following tools: == | ||
+ | |||
+ | * Medium flat blade screw driver | ||
+ | * 3mm, 5/64, 5/32, 3/32 and 7/64 inch hex wrenches | ||
+ | |||
+ | The hex wrenches are provided by ASI. | ||
+ | |||
+ | == The procedure has three parts: == | ||
+ | |||
+ | |||
+ | * Removing the left zoom knob | ||
+ | * Installing the automated zoom drive. | ||
+ | * Installing and aligning the automated filter drive assembly. | ||
+ | |||
+ | ===== Part 1 - Removing the Left Zoom Knob ===== | ||
+ | |||
+ | |||
+ | Remove the left zoom knob from the microscope as follows: | ||
+ | | ||
+ | [{{ :: | ||
+ | [{{ :: | ||
+ | [{{ :: | ||
+ | | ||
+ | * Use screwdriver to remove screw | ||
+ | * Remove knob & brass piece | ||
+ | |||
+ | |||
+ | ===== Part 2 - Preparing The Zoom Drive ===== | ||
+ | |||
+ | [{{ :: | ||
+ | [{{ :: | ||
+ | [{{ :: | ||
+ | |||
+ | Locate the zoom motor drive & loosen the YZ & X axis adjustment screws as shown in figures 5&6. | ||
+ | |||
+ | |||
+ | ===== Step-3 Installing & Aligning the Motor Drive ===== | ||
+ | |||
+ | [{{ :: | ||
+ | [{{ :: | ||
+ | [{{ :: | ||
+ | |||
+ | a.) With the XYZ adjustment screws loose (step 2) slide the zoom drive onto the microscope as shown in the above figures. | ||
+ | |||
+ | {{ :: | ||
+ | |||
+ | b) Use the 7/64 Allen wrench to tighten the drive shaft clamp as shown in figure 10. Please note that this clamp must be securely tightened to insure that the drive will not slip | ||
+ | |||
+ | c) Align the motor drive by moving it up and down, forward and backward slightly while turning the right zoom knob until it is in the position where minimum drag is felt on the right zoom knob. | ||
+ | |||
+ | d) Recheck the alignment by noting the drag on the right zoom knob. No noticeable drag should be felt Repeat the steps above if necessary. | ||
+ | |||
+ | |||
+ | ===== Step 4 -Installing the motor drive cover plate & fine focus knob. ===== | ||
+ | |||
+ | [{{ :: | ||
+ | |||
+ | [{{ :: | ||
+ | |||
+ | |||
+ | a) Locate the motor drive cover. Remove the 4/40 button head screws from the drive with the 1/16 “ Allen wrench. Position the motor drive covert over the motor drive assembly and secure in place using the 4/40 button head screws as shown in figure 11. | ||
+ | |||
+ | b) Locate the left hand knob an slide it over the shaft extension as shown in figure 12. Please note the position of one of the set screws that secures the knob to the shaft should be aligned with the flat spot on the shaft as shown. Press the knob all of the way on and secure it in place by using the 1/16" Allen wrench to tighten the two set screws. | ||
+ | |||
+ | This completes the procedure for installing the ASI automated zoom drive on to the Leica Stereo Zoom Microscope. | ||
+ | |||
+ | ===== Part 3- Installing and Aligning the Automated Filter Changer ===== | ||
+ | |||
+ | {{ :: | ||
+ | |||
+ | ==== Over View ==== | ||
+ | |||
+ | |||
+ | |||
+ | The filter changer utilizes a Hall-effect sensor with magnets mounted to the filter holders to determine where the motor should stop, and which filter is the home filter position. | ||
+ | If new magnets need to be installed, be sure to follow this polarity convention. | ||
+ | |||
+ | ==== Step 1. Installing the magnets ==== | ||
+ | |||
+ | [{{ :: | ||
+ | [{{ :: | ||
+ | [{{ :: | ||
+ | |||
+ | a) The magnets are secured with an adhesive backing. | ||
+ | |||
+ | b) After installing the magnets as described in the over view and shown in figures 1 - 3 above place the filters in the holders and install the holders into the microscope as described in the microscope manual. | ||
+ | |||
+ | [{{ :: | ||
+ | |||
+ | c) It helps to make a mark to signify a reference | ||
+ | |||
+ | [{{ :: | ||

+ | [{{ :: | ||
+ | |||
+ | d) Install the filter wheel drive as shown in figures 5 - 6 above. | ||
+ | |||
+ | [{{ :: | ||
+ | [{{ :: | ||
+ | |||
+ | e) Use the 3/32 Allen wrench to loosen the screw that clamps the motor in place. | ||
+ | |||
+ | |||
+ | f) Test for the correct positioning of the filter wheel drive by connecting the cables as shown below in figures 10 - 12 | ||
+ | |||
+ | [{{ :: | ||
+ | [{{ :: | ||
+ | [{{ :: | ||
+ | |||
+ | |||
+ | after connecting cables for XY stage, Zoom drive, Filter wheel, Power and Computer control power the controller up. As mentioned the filter changer utilizes a Hall-effect sensor with magnets mounted to the filter holders to determine where the motor should stop, and which filter is the home filter position. | ||
+ | |||
+ | Press and hold the @ button for a second and then release it. The LCD display should show a ‘+’ when the home (0) filter is located. Pressing the @ button momentarily again should direct the filter wheel to the next detent position, and the LCD display should show a ‘-’ | ||
+ | |||
+ | The magnets must be positioned correctly on the filter holder so that the motor stops when the filters are in the detent / properly aligned position. | ||
