Auxiliary Switches
Adjustable cams actuate the auxiliary switches. These cams
can be set to actuate the switches at any angle within the
stroke of the motor. Select switch differential of 1° or 10°.
Motors with factory-added auxiliary switches are shipped in
the closed position (fully counterclockwise, as viewed from the
power end). Auxiliary cam default actuates the switches 30°
from full open with a 1° differential. With the motor in the
closed (fully counterclockwise) position, the auxiliary switch
breaks contacts R-B. See Fig. 8 (or the auxiliary switch
Instruction Sheet) for auxiliary switch wiring.
NOTE: Auxiliary switches can only be added to motors that
include auxiliary switch cams. (These cams cannot
be field-added.)
TRADELINE motors are shipped with auxiliary switch cams
that permit acceptance of 220736A,B Internal Auxiliary Switch
Kits. Refer to form 63-2228 for 220736A,B installation
instructions.
