4.6.3 Absolute analog position output
The absolute analog position sensor is a multitude non-con-
tact magnetic sensor. It provides a signal indicating the posi-
tion of the linear actuator. the output signal is 0 ~ 5V DC volt-
age (current output 5 mA max). The electrical specification
and resolution refer to date sheet, the wires connecting refer
to 6.4.1 Wiring scheme.

NOTE
When actuator with POT or the analog output, don’t rotate the push
tube 45 degree and don’t connect to power before the actuator is
installed into device (see picture below) Otherwise would demage
the potentiometer or the analog sensor components.
WARNING
4.6.4 Encoder
Dual hall sensor for incremental position feedback. It outputs
signals when the actuator is moving outwards and inwards
respectively. The output signals, channel 1 and 2, are ±90°,
see the figure below. The electrical specification as on the
data sheet.
The supply voltage to the encoder must be in the range 4 to
20 V DC)

4.6.5 Manual Override
Manual override option provides a solution to move the push
tube manually and without tool when power failure. The un-
screwed cover can be used as a hand crank. Also a power
tool can be used to drive the cover by the hexagon head.
Please stop operating the override device when the clutch is
activated.
The structure and operating instruction see the figure below.

NOTE
The directions showed on the inner side of the motor front represent

DANGER
Danger of injury caused by moving components!
Rotating components can cause severe injury.
Therefore:
• Do not operate the manual override deice when actuator cable is
connecting with power supplier.
