Adjusting the angle setting
When adjusting the angle of the plate-light path in the factory, a
compromise was sought between minimal angular deviation and
minimal friction of the arm.
If the measurement shows that the angle falls outside the given
tolerance, the angle must NOT be adjusted to a minimum deviation,
but just within the tolerance. The new setting must be between the
old setting and the optimal installation.
After adjustment, the friction of the arm must be checked. This is
done with the aid of a spring pressure gauge which is applied to the
counterweight. The friction of the arm, measured over the hole
deflection, should not exceed 30 Nm.
If the friction appears to be too high, the setting must be returned to
the old value. Then replace the lens unit with a new one and check
the angle again.
If the angle does not fall within tolerance, the arm must be replaced.
Adjusting the angle is done as follows:
Place the frame on the service supports 4822 395 30202.
Loosen the screws C (see Fig.) until bearing plate D can be moved.
Correct the angle setting by moving the bearing plate in the
direction shown in the figure.
Tighten the screws C, making sure that the setting does not change.
Then check the angle setting again in two steps.
Note:
After adjusting the angle, the height adjustment of the turntable
must be checked
