9. Manual operation
The actuator may be operated manually for purposes of setting and commis-
sioning 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 K-1).
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 K), if necessary, push it back manually.
Operating the change-over lever while the motor is running
(figure L-1) can lead to increased wear at the change-over
mechanism.
.
Turn handwheel into desired direction (figure 13-2).
Disengaging manual operation
Manual operation is automatically disengaged when motor is started again.
The handwheel does not rotate during motor operation.
