Overview

R-4820.A

Overview 1. This repair manual covers Ti-E model. 2. This repair manual has been prepared as a textbook for the repair training session. It provides step-by-step instructions that are designed to enable service personnel to gain an understanding of the structure of the mechanical and optical systems, and to learn how to repair them. 3. When you conduct repair work, be very careful of any sharp edges, projecting object, and conductive parts to avoid injury or electric shock. (It is recommended that you unplug the power cable and wear safety gloves while you are conducting repair work.)

Points on Repair ○ ○ ○

Use a Phillips screwdriver that appropriately fits the slot in a screw head used. Clean plastic parts with mild detergent. Ether, thinner, alcohol and other organic solvents may cause discoloration or deterioration. To clean the glass parts, first blow the dust off them and then wipe them using lens tissue moistened with alcohol (or alcohol-ether mixture).

Fig. 6-19 3. Fit the race support into the up-down movement base. 4. Slide the roller race to fit to the unit and secure the race temporarily with the hexagonal bolts (#0456x3). 5. Attach the captive screw for the cylindrical roller bearing (#0454, #0464) you removed in Step 6-1-14 to the roller race and apply adhesive (#757) to the screw. 6. When you place the retainer on the roller race, adjust the position of the retainer so that the center of its movable part will align with that of the movable part of the up-down movement unit. 7. Move the race support of the movable parts to the center, tighten the adjusting screws (#0463x3) (Fig. 6-13) and push the roller race you temporarily secured in Step 6-2-4 against the movable race support. 8. When you move the race support, the cylindrical roller bearing and retainer should smoothly move. Make sure that the race support of the movable parts smoothly moves and no uneven or rough movements exist. Using a spring scale, push the movable part and ensure that the initial resistance when it starts moving is in the range from 100 to 150 g. If the initial resistance is outside the above range, follow Step 6-2-7 to adjust it using the adjusting screw. Then, tighten the bolts (#0456x3) you temporarily secured in Step 6-2-4. * Tightening the bolts (#0456x3) may adversely affect the movement of the race support of the movable parts. If that happens, repeat Step 6-2-7. 9. Apply adhesive (#757) to the threads of the adjusting screws (#0463x3) you tightened in Step 6-2-7.

Remove the crosshair eyepiece with the dioptric telescope attached to it from the reference straight tube (for body tube) of the observation system and attach it to Ti Output port straight tube A or B on the left-side port. 16. Following the same procedures in Steps 7 through 11, adjust the focus of the left-side port. 17. Following the procedures given in 12-2-2, check optical axis on the right- and left-side ports and, if necessary, readjust it. 18. When it is found that the specification is not satisfied when rechecking, readjust the focus following the procedures in Steps 3 through 16. Now, the focusing and optical axis adjustment on the right- and left-side ports has been completed.

13-1-1. Preparation 1. Remove the up-down movement unit. (Refer to 5-2. Removing the Optical Unit, and 6-1. Disassembling the Up-Down Movement Unit.) 2. Connect J2 connector on preamplifier board (#0702) and J4 connector on interface board (#0802) using relay cable (#0821). 3. Connect the oscilloscope probes to the preamplifier board as described below. (Refer to Fig. 13-1.) • CH1 ⇒ TP1 (AX) • CH2 ⇒ TP2 (BX) • GND ⇒ TP3 (A GND) 4. Set the oscilloscope as shown below. • Sweep time ⇒ X-Y (Lissajous waveform mode) • Input mode ⇒ AC • Voltage ⇒ 1 V/div 5. Set the variable resistors on the preamplifier board beforehand as described below. • Turn VR1 and VR3 to the center position. • Turn VR2 and VR4 in the clockwise direction as far as they will go (to minimize the gain of the amplifier). 6. Connect the AC adapter output cable to the microscope and plug in the microscope to turn it on.

13-1. Encoder Adjustment 13-1-2. Adjustment of Tilt of Encoder Head • Tilt the head toward the glass scale rotating about the LED sleeve so that the waveform is maximized. Note 1: The waveform at this point does not need to be a perfect circle. 2: The index, LED, amplitude and center level must be adjusted while moving the up-down movement unit. 1) Slightly loosen the two hexagonal bolts securing the index. Rotate the index in the direction of rotation about the LED sleeve to a position where the Lissajous waveform is maximized and tighten the bolts to secure the index.

Adjust the following variable resistors so that the PP value of the waveform is 3.2 V while moving the up-down movement unit. Refer to Fig. 13-1 for the locations of the variable resistors on the board. • Use VR2 for AX adjustment. • Use VR4 for BX adjustment.

Specification: PP value: 2.4 to 4 V (Reference value: 3.2 V ± 0.2 V for a velocity of 0.394 in./sec) If the signal is saturated as shown in Fig. 13-6, carry out the following adjustment of the variable resistors.

Setting procedure: (1) Mount the objective lens "MRH00401 Plan Flour 40x" in the nosepiece and move it into the optical path. (2) As a specimen, place a glass bottom dish (filled with water) on the stage. (3) Press the [d] switch until the offset lens reaches the position "offset = 0". (The "offset = 0" adjustment must have been completed before starting this adjustment procedure.) (4) Using the manual handle of the microscope, move the tip of the objective lens at least 3 mm away from surface "A" of the glass bottom dish. Surface "B"

Press the [a] switch. (A short beep sounds.) Move the TE2000E's focus drive in fine mode. • Perform pre-adjustment, adjusting the LED light intensity and executing coarse search of focus drive position. • A short beep sounds continually during the pre-adjustment. (7) Back to the adjustment procedure, execute fine search of focus drive position. • A short beep followed by silence sounds continually during the adjustment procedure. (8) The fine search finishes after while, when the beeping stops. (9) After 10 seconds, a long beep sounds and the "POWER" LED lights. This completes the setting procedure. CAUTION: Leave the focusing knob intact during steps (6) and (8). - 103 -

(1) If an asterisk "*" is shown to the left of "L": [a]SW : Increments IR LED DA by four. [d]SW : Decrements IR LED DA by four. (2) If an asterisk "*" is shown to the left of "O": [a]SW : The offset lens is ready to drive. [d]SW : Set the offset zero position and write it into EEPROM (the same effect as by the communication command [cYEE4]).

NOTE: (1) Exposure time (ND) adjustment Use the [Z-RESET] key to adjust exposure time (ND). Increasing the ND number reduces the CMOS exposure time and lowers the level of AF signal of PFS (the signal can be observed on an oscilloscope). → Use this control if the AF signal is saturated even when the LED output indication (b-3 to b-6) is "0." (2) Optical-path change (EYE100) When an asterisk "*" is shown to the left of "O", pressing [R100] (=[c]) sets the optical path to EYE100.
