EASY SETUP PROCEDURE

MOUNTING OF UNIT

Mount the assembly and couple the input shaft to

the driving member, with the shaft keyway up and in

line with the positioning arrow on the bearing end

plate. The machine should be in the start cycle

position.

ESTABLISHING CAM SHAFT

DIRECTION OF ROTATION

Cam settings should be made with the cam shaft

uppermost to the viewer. The picture at the top

illustrates this viewing position and also shows the

adjusting tool being applied to the adjusting wheel.

Shaft rotation is always established off the right

end of the unit even when the input shaft, whether

direct or through a gear reducer, is situated at the

left end. As an aid to designating shaft rotation

when gear reducer is used, consult page 10 of the

1980 Catalog Section.

CAM SETTINGS

For clockwise rotation, set "make" angle with the

black dial and "break" with the red dial for dwell

settings less than 180° or greater. Reverse colors

for dwells greater than 180°.

For counterclockwise rotation, set "make" angle

with the white dial and "break" with the yellow

dial. Reverse colors for dwells greater than 180°.

Switch connections should be made in accordance

2LLMM

with the illustrations to the right, which, incidentally,

are both clockwise rotating examples.
