5.1 Operating mode

5.1.1 Normal mode

The motor triggered by the power electronics drives the output shaft (9) via oil-lubricated spur gears.

The drive lever mounted on the shaft transmits rotary motion to the valve.

The brake built in the motor (5) acts as a retainer when the power is off.

5.1.2 Handwheel mode

- Allows you to move the actuator manually when the electrical power is off.

- Turn the lock lever (4) clockwise

- Turn the handwheel (7) to move the lever to the wanted position.

- Release the lock lever.

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 handwheel. Otherwise, you might damage the actuator

or valve.
