9. Manual operation
The actuator may be operated manually for purposes of setting and com
-
missioning 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 centre of the handwheel to approx. 85°,
while slightly turning the handwheel back and forth until manual operation
engages (figure 18).
Manual force is sufficient for operating the change-over
le
ver. 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 19), if necessary, push it back manually.
Operating the change-over lever while the motor is running
(figure
20) can lead to increased wear at the change-over
mechanism.
.
Turn handwheel into desired direction (figure 21).
Disengaging manual operation
Manual operation is automatically disengaged when motor is started again.
The handwheel does not rotate during motor operation.
