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.
