Ewellix CAHB-2 Series - Changes And Modifications On The Actuator

8
CAHB-20 series
The following safety features may have been
installed:
A thermal switch is integrated into the motor inside to pre-
vent damage from overheating. If overheating occurs when
theactuatorisoperating(overspecication),theswitch
wouldbeactivated,thepowerwouldbecut-o;afterthe
temperaturefallsbelowthethreshold,theswitchwillrestore.
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.
E design only
CAUTION
Continued operation of the clutch can result in overheating and
damagetothelinearactuator.Ifclutchactivates,switchoffpower
immediately.
