BEAM SPLITTER (MIRRORED CUBE) ADJUSTMENT
1.
Turn the Z adjustment knob counterclockwise completely. (Vacuum Tube should be at its
maximum length.)
Turn Z adjustment knob clockwise, making approximately 1/2 turn.
Remove the PCB blank and install the Gun Sight Alignment Assembly in its place (with one
plate) onto RBH-C Board Holder. Refer to Figure A in the calibration verification procedure for
more details. (If necessary)
Retreat the beam splitter and move the Vacuum Pickup Head Assembly into the low position
(vacuum head should be just above the pattern plate).
Position the circle on the fixed pattern plate of the Gun Sight Assembly over the center of the
vacuum cup. Refer to Figure A in the Calibration Verification Procedure for more details.
Move the vacuum head to the top position. Be sure to lock X, Y movement using locking lever
(Refer to Fig. A on page 2.)
Draw beam splitter out from arm assembly, use lever on right side of arm assembly.
Using the zoom lens magnify the circle on the fixed pattern plate until the circle fills the video
screen. Using the two positioning knobs on the vision assembly, move the circle plate to the
center of the screen. (See DWG # 7).
Retreat the beam splitter and install the removable pattern plate (face down) onto the dowel pin.
Move the vacuum head to the low position until the vacuum head touches the pattern plate.
Activate the vacuum and pick up the pattern plate. Move the vacuum pickup head to the top
position.
Draw beam splitter out from arm assembly using lever on right side of arm assembly.
Adjust illumination (top and bottom) by rotating the light adjustment knob (located on the left side
of the unit) to obtain a clear picture of both images.
While viewing the screen, superimpose the images of the two plates. This is done by performing
tasks a, b, c, below. Do not move the board holder and be careful not to touch the top pattern
plate. If you do touch the top pattern plate, please go back to step 4 above.

Move the Vacuum Head Assembly to the top position and install
size 0.4 Vacuum Cup (P/N 19790) onto the vacuum tube.
(See DWG # 5 below.)
Using a 1/16” hex wrench loosen both mounting screws, making 2
turns counterclockwise. (See DWG # 6A)
Using a 0.05” hex wrench turn both calibration set screws until
proper alignment is achieved. (See DWG # 6b)
Tighten the mounting screws. This should not affect calibration.
