The position of each lens is set manually by turning the rotating plate in the desired
FLAT
or
SCOPE
lens position. The aperture opening matching the lens is also set manually by moving
the aperture handle on the trap and gate
up
for
FLAT
or
down
for
SCOPE
.

The automatic turret is electronically driven by a DC motor that controls the movements of
the lens holder and the aperture. The electronics are initiated by the automation. The
interfacing is done through TB4 (see schematic p/n 503480). The switching from
SCOPE
to
FLAT
or vice versa is done with a pulse. The common terminal TB4-C is briefly connected to
the
SCOPE
terminal of TB4-S to move the turret to the
SCOPE
lens position. A momentary
connection between the
COMMON
and
FLAT
terminals TB4-F will move the turret to the
FLAT
lens position.
