CAUTION
Topreventdamagefromoverheating,donottrytooperate
actuator until its temperature has fallen below the threshold for
the switch to operate.
A driving 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lin-
ear motion.
CAUTION
Continued operation of the clutch can result in overheating and
damagetothelinearactuator.Ifclutchactivates,switchoffpower
immediately.
2.4 Changes and

4.2 Brief description
Overview
This actuator is to be used exclusively for installation into a
dynamiccentric-compressionortensile-loadedlift.
The linear actuator consists of a motor part (4),agearunit
(7) and a linear unit (3),connectedwitheachotherbyabay-
onet joint.
The actuator consists of a direct current motor with helical
gearwhichsetsinmotionageartransmissionsystem.Via
thedrivingscrewandnut,therotationofgearistransformed
into a linear motion of the actuator.
The front hinge head (1) and the rear hinge head (6) transmit
the actuator power to both sides of the application.
Fig. 8
4.3 Special features
Mechanical overload protection
The actuator contains a mechanical overload protection unit
(clutch).This overload protection unit will activate if the linear
unit of the actuator overloads. This activation will avoid to
pushorpulloverthemaximumforcedenedonthedata-
sheet and will protect the motor and gear unit from being
damaged.
CAUTION
Continued operation of the clutch can result in overheating and
damagetothelinearactuator.Ifclutchactivates,switchoffpower
immediately.
Thermal protection
Thethermalswitchbuilt-inthemotorwillswitchothe
power of the motor in case of over heat of the motor. It will
automatically reset when the temperature decreases.
Overload or more frequent operating the actuator over the
maxdutycyclesdenedonthedatasheetwouldleadto
motor overheating.
CAUTION
To prevent damage from overheating when the actuator stop with a
highmotortemperature,donotrestarttheactuatorbutwaituntilthe
temperature decreases.
Gore automotive vent
The vent allows the equalization of the pressure inside the
actuatorwhenitisoperated,thatwillinsureanoptimumus-
age of the sealing system
