You can configure the NSS/BAS assembly for three different settings:
I. NSS only.
II. NSS with BAS for units where clockwise (CW) handle rotation results in reverse motion.
III. NSS with BAS for units where counterclockwise (CCW) handle rotation results in reverse motion.
The setting must be in accordance with the configuration of the unit. See the model code if uncertain of
the type of NSS setting the machine is equipped with.
Adjustment is normally not required unless the function of the NSS is changed (between I, II, or III).
Adjustment of the NSS or NSS and BAS requires a special alignment tool. Dimensions appear at right. The
tool positions the cam precisely relative to the control housing.
