Self-locking
Rotary actuators for modulating duty are
self-locking actuators.
The gear ratio is i=40.

Manual mode
>> Switchover only when drive is at standstill! <<
Switchover takes place by pressing in the hand
crank/hand wheel, motor stops operating automati-
cally.
Electrical operation restarts automatically after
releasing hand crank/hand wheel.
Direction of rotation: Turning hand crank / hand
wheel clockwise results in clockwise rotation of
output shaft
(Exception: 2SA757.- and 2SA758.-).
Self-locking: The hand wheel acts directly on the
motor shaft when turned by hand; the self-locking
function is thus retained for self-locking actuators.
