The following safety features may have been installed:

In its standard version, the actuator does not feature a thermal
switch protection and can be damaged through overheating.

A thermal limit switch is an option and can be integrated in the

motor housing.

A ball screw nut converts the rotation of the gear unit into linear

motion. If an overload occurs when the actuator is operating, a ball
detent clutch will operate, thus stopping linear motion.

Thermal switch (optional)

To prevent damage from overheating, do not try to operate
actuator until its temperature has fallen below the threshold for
the switch to operate.

C A U T I O N

Overload protection

Continued operation of the clutch can result in overheating and
damage to the linear actuator. If clutch activates, switch off
power immediately.

C A U T I O N

Clutch activation can cause the limit switch to stop functioning.
If this happens, have an SKF engineer adjust it so that it again
operates properly.
