For HS16, TS, & PS Models
The HS16, TS, and PS switches are supplied with the stopper plate set for the
maximum number of positions allowed for that model. Prior to installation,
the desired stopper setting should be made:
1.
2.

4.
Standard Hardware Supplied with HS, TS, and PS:
Be sure the shaft is turned counterclockwise to the extreme left. If the
shaft is not turned counterclockwise to the extreme left, proper setting
cannot be achieved.
Loosen the nut far enough to allow raising the stopper plate for resetting.
Insert the stopper in the numbered hole for the desired stopper setting.
Satisfactory switch functioning cannot be assured if the stopper plate is
not properly positioned.
Tighten the nut firmly against the stopped plate.
