Figure 4.3 – Setting the open and closed contacts
4.5.3 Combination of Contacts (Refer to Figure 4.2)
The rotor segments can be separated and rotated through 90 degrees to give various combinations of
normally open or normally closed contacts to each rotor.
1. Remove Nuts (piece 8) and Fillister Head Machine Screws (piece 5, for a total of two fasteners on
each side of the switch).
2. Remove complete contact assembly from the back plate.
3. Rearrange cams on the camshaft to produce the required combination of contacts.
4. Replace contact assembly on back-plate (ensuring that the registers fit correctly) and secure with
the machine screw and nuts.
5. Set limits according to the procedure above.

2. Place the valve in the fully “close” position.
3. Loosen the round head machine screw which holds the pointer in place, move the pointer to the “O”
position, and retighten the screw.
The indicator is now set.
