Solenoid 1 Adjustment for Quintic Position
If the movable Quintic lens element travels at too high or too low a speed, its final
(focused) position may not be correct for the distance measured by the camera’s
sonar system. (If the Quintic moves too fast, for example, the Catch Pawl may not
be able to stop it at the correct position.)
Quintic speed can be adjusted as follows:
1. Remove the Top Cover from the camera (Figure 3-15).
Warning:
HIGH VOLTAGE EXPOSURE! Up to 320V
is present on top flash tube terminal (green wire)
and at various other locations on the strobe board.
2. Using a small screwdriver, carefully turn the adjusting screw of Solenoid 1
(Figure 3-20) one-half turn at a time. Turn the screw counter-clockwise to increase
Quintic speed, clockwise to decrease Quintic speed.
3. Put the Test Top Cover in place on the camera.
4. Retest the camera to verify that the Catch Pawl catches (stops) the Quintic at the
correct position. If it does not, readjust the Solenoid 1 adjusting screw, one-half turn
at a time, until the Quintic is caught by the Catch Pawl.
5. When the proper Quintic catch is achieved, replace the Test Top Cover with the
camera’s own Top Cover.
6. If steps 1-3 fail to produce correct Quintic catch, disassemble the camera to the
shutter level and inspect the plunger of Solenoid 1, the Catch Pawl and the Quintic
element for dirt, damage, binding, etc. Correct any problems that are found,
reassemble the shutter and retest the camera.
