05.05. Overcurrent Protection
In the event of an obstruction or an excessive load,
the overcurrent protection feature will cut off the
current at 3 A to protect the actuator. The overcur-
rent protection system resets after 10 seconds when
activated to enable normal operation.
05.06. Electronic Limit Switches (opt.)
When the actuator reaches its fully extended or
fully retracted positions, an electronic limit switch
automatically cuts off the current to prevent damage
to the motor. When it reaches either stroke end point,
the actuator can move only in the opposite direction,
until it is separated from the limit and it can resume its
normal function and move freely in either direction.
05.07. Position feedback (opt.)
The position feedback potentiometer is feeded with a
5 VDC voltage. Depending on the position of the rod,
the potentiometer sends an analog signal between
0 VDC (actuator fully retracted) and 5 VDC (actuator
fully extended).
