4.5.2 SMB-000 and SMB-00 “C Style” Double Torque Switch
NOTE: Torque settings must be made with the switch mounted in the actuator.
NOTE: See Section 4.3.3 for wiring connection requirements.
Piece numbers correspond to Figure 4.5 and Table 4.7.
To set the torque switch:
1. Verify all electric power is OFF.
2. For the open or close direction torque switch, loosen Machine Screw (piece #35) and set Pointer
(piece #7) at the desired torque setting. The higher the number, the higher the torque output of
the actuator.
3. Tighten Machine Screw (piece #35).
4. For torque seated valves, operate the valve electrically to seat the valve. Ensure tight shut-off by
tripping the torque switch contacts.
