6. Manual operation The actuator may be operated manually for purposes of setting and

commissioning, and in case of motor failure or power failure.

Manual operation is engaged by an internal change-over mechanism.

Engaging manual operation:

Lift up change-over lever in the center of the handwheel to approx. 85°, while

slightly turning the handwheel back and forth until manual operation engages

(figure C).

Manual force is sufficient for operating the change-over lever. It is

not necessary to use an extension. Excessive force may damage

the change-over mechanism.

Release change-over lever (should snap back into initial position by spring

action, figure D), if necessary, push it back manually.

Operating the change-over lever while the motor is running

(figure E) can lead to increased wear at the change-over

mechanism.

Turn handwheel in desired direction (figure F).

Disengaging manual operation:

Manual operation is automatically disengaged when the motor is started again.

The handwheel does not rotate during motor operation.
