4.1 Operating mode

4.1.1 Common 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, which is integrated in the motor (5), acts as a retainer when the power is off.
4.1.2 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.
CAUTION The friction clutch is designed so that a handwheel force of approx. 11 N providese 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.
