Manual operation
For purposes of setting and commissioning, in case of motor failure or power failure,
the actuator may be operated manually. Manual operation is engaged by an internal
change-over mechanism.

When using brake motors, note that the motor is disengaged during manual operation.
For this reason, the brake motor cannot sustain any load during manual operation.
The load must be sustained via the handwheel.
