5.1 Operation

5.2 Normal mode

The motor triggered by the electronics drives the axially fixed drive sleeve/nut assembly
via greased spur gears. A ball bearing screw radially fixed by an anti-twist arrester con-
verts the rotary to a linear motion.
The brake built in the motor acts as a retainer when the power is off.
The friction clutch is designed such that a handwheel force of around 11 N suffices to
create the rated torque on the actuator. If you should feel a considerable counter-force
when moving the actuator by hand, do not increase the force you apply to the hand-
wheel. Otherwise, you might damage the actuator or valve

5.3 Handwheel mode

- Allows you to move the actuator manually when the electrical power is off.
- Turn the handwheel lock lever clockwise to unlock the handwheel.
- Turn the handwheel to move the thrust rod to the desired position.
- Release the locking lever to lock the handwheel again.
