LWG208 Length/angle sensor installation
 Length/Angle sensor consists of housing, a spring-loaded cable drum with
measuring cable and mounting equipment.
 Make the boom horizontal. Make sure the sensor is parallel with the main
boom and the bracket is straight before fixing the bracket by bolts.
 Make sure there are at least two turns measuring cable in the drum when
the cable is pulled out. The
recommended length of the cable = effective
needed measure two turns cable+ about 1 meter cable for connection.
 The cable drum of the sensor must rotate following the direction of the
cable being pulled out. Rotate the cable drum 4 to 5 turns to pre-tighten
the drum and then pull out the cable to the tip of the boom for connection.
 Use the guiding wheel to keep the measuring cable at the same level.
Place guiding wheels so as to prevent cable deflection, which will result in
the cable being difficult to pull out and to retract smoothly:
o
Make sure the first guiding wheel A is in front of the sensor center
1.5m
～
2m. Ensure the guiding wheel turn width is slightly less than or
equal to the cable drum turn width.
o
Make sure the center of the cable guiding wheel A and other wheels
are in alignment and also parallel with the main boom.
 The measuring cable should be fixed to the tip of the boom tightly and the
fixed point should be at the same level with the sensor center to guarantee
