Camera body 201F

Checks & Adjustments 3:7

5:4 VIEWFINDER SIGNAL: Check that the viewfinder LED is flashing.

Note! The sync cable must be connected to the TTL connector.

5:5 CURRENT: Check the consumption (max. 10 mA at 5.6 volt) and the drain

(max. 20 uA at 5.6 volt).

5:6 SHUTTER: Start by adjusting the travel times. Use 1/1000 sec. and adjust the

spring housing until both curtains have a speed between 9.6 - 9.9 ms. (0 ± 0.11 ms).

At this point, also make a final adjustment of the braking mechanism if necessary.

The brake is checked as follows: Release the camera. Rotate the 2nd shutter gear

(Pos No. 25, page 16:2) and count the number of times the catch (Pos No. 4, page

17) and the brake plate (Pos No. 3, page 17) engage. (Min. 4 times). For an

adjustment use the nut driver 903755 or 903474. (See page 3:9).

Check/adjust the speed 1/1000 sec. Use the "shutter speed" potentiometer for

an adjustment. (See page 3:9). Max. deviation ± 0.3 EV.

5:7 FLASH SYNC: Check/adjust the flash sync. The delay is adjusted to 0 - 0.20 ms by

altering the position of the first sync contact. (See page 3:9).

5:8 FLASH METERING: Check/adjust the flash meter. Use the "flash meter"

potentiometer for adjustment. (See page 3:9). Max. deviation ± 0.3 EV. Use the

setting ISO 100 and light output EV 15.

5:9 C-POSITION: Check/adjust the C-position. It is adjusted by extending or

shortening the release arm 103389. (See page 3:9).

6. Make sure the four centering screws (Pos No. 14 and 17, page 10:2) are screwed in

and then put the camera body in to the shell. Note! The control panel must go in

first and then carefully follow with the camera body without damaging the coaxial

and ribbon cable. Do not forget the pre-release button.

7. After aligning the rear plate/shell tighten the two rear screws (Pos No. 32, page 5:2)

and adjust, if necessary, the horizontal relationship between the speed ring and the

shell by the screws (Pos No. 14, page 10:2) which are accessible through the shell.

8. Adjust the vertical relationship between the speed ring and the shell by the screws

(Pos No. 17, page 10:2) which are accessible through the shell and then tighten

the two front screws (Pos No. 34, page 5:2).

9. Check the upper edge alignment of rear plate and shell. Adjust, if necessary, by the

two screws (Pos No. 47, page 9:2) which are accessible through the shell.

Note! The rear edge of the shell must not protrude over the rear plate at any point.

10. Attach the control panel incl. the speed ring locking pin, winding crank mechanism,

slide, speed ring grip and inner cover.
