6.6.4. Timing Adjustments – Turret and Aperture Motor
The turret motor and the aperture motor are controlled from the PC board, which is mounted
on the non-operator side of the projector. Both motors are timed. One timer goes to the
FLAT
position; another timer goes to the
SCOPE
position. The on-time for the
FLAT
position is
adjusted with a trimpot located at the lower side of the PC board.
When user is facing front of projector, lensholder plate rotates
clockwise to
SCOPE position and counter-clockwise to FLAT position. If
lensholder plate turns in opposite direction, reverse quick-connects on
turret motor.
Turning the trimpot clockwise shortens the time. The timing is set approximately 0.5
seconds longer than the time needed for the turret motor to turn the lensholder plate from the
FLAT
position to the
SCOPE
position and vice versa. The drive wheel will overrun for 0.5
second. The
SCOPE
on-time is adjusted in the same manner, using the trimpot located on the
upper side of the PC board.
