5.1 Operation

5.1.1 Common mode

The motor (8) triggered by the power electronics drives the output shaft (5) via oil-lubri-

cated spur gears and the intermediate gear (10). The shaft transfers the torque via a le-

ver (3) and ball-and-socket joints (2) to the final control element. A position sensor

detects backlash-free the current shaft position

Adjustable mechanical limit stops absorb possible torque peaks in the end position.

The brake on the rear motor shaft end 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.

- Press down the handwheel lock (9).

- Turn the handwheel (1) to move the output lever (3) to the desired position

- Release the lock (9)
