Camera body 203FE - 205FCC - 205TCC
CAUTION! When handling the circuit boards a grounded bench mat
and a wrist strap must be used to prevent ESD damage.
Carry out the following checks/adjustments when a camera body is
reassembled after a repair.
Note! Point 1 - 7 without camera shell.
1. The camera body focal length is checked by using the gauge V-2229 together with the ruler
and indicator clock. The focal length is 71.40 mm ± 0.03 mm. Adjustment slots on the
chassis and the bottom mechanism plate.
2.* Secure the camera in the gauge V-2229 by the adapter 904759. Check the 45º
mirror angle with the sighting tube. The image seen, should be symmetrical. Adjust, if
necessary, the four supports in the mirror box by using the tools 901046 (front supports)
and 904018 (rear supports).
3.* Check the flatness of the screen. Use the screen adapter V-4705 and the ruler with the
indicator clock. The same measurement should be obtained at all four corners.
Adjust, if necessary, by the four screws (Pos No. 28, page 15).
4.* After the screen is correctly levelled the height must also be checked. Use the collimator
V-4151, the screen adapter V-4705 and the microscope V-2236.
The image seen in the microscope should be the red line central between the two green lines.
Recheck the flatness.
5. Use the tool 902658 or V-2075/2151 for checking of the front key angle. Adjust if necessary.
Cocked position 8° - 9° 3 Ncm. Overtravel 12° - 14° 14 Ncm.
6. Temporarily fit the control panel to the camera body and secure it with a piece of tape.
Use the nut driver 903755 or 903474.
7. Connect the camera body to the Service Test System and go through all checks in the
given order according to the 203/205 menu. Note! pos. 7:1 to 7:7 without sensor head
and light source.
7:1 CAMERA STATUS. Make sure all switches are working properly.
Note! The speed ring in C-position.
If the contact flex has been removed at any time, the timing between the pre-release switch
(PRS) and the mirror must be checked.
Mount the test shell, 905002, with four screws. Fit the exposure gauge V-2354 in the release
button and slowly rotate the micrometer clockwise and observe when the mirror is released.
At the same time (not before) the PRS should change from "open" to "closed" on the screen.
A slight delay is acceptable. This corresponds to 1.5 divisions on the scale.
Adjust, if necessary, by altering the position of the rear section of the contact flex
