3 INSTALLATION
3.1
Series 1-L Display
The back of the display is fitted with a ball-joint mount. The joint base should be secured
with 2 x M5 bolts on fixing holes at 48.5mm spacing, and can be mounted on a horizontal,
angled, or vertical surface as appropriate. The display should be mounted within easy reach
of the operator, in a position that avoids direct sunlight on the indicator LEDs and exposure
to water ingress. Care should be taken to
ensure that the display is mounted to a surface or structure that is capable of supporting the
display when travelling over rough terrain.
A 2m long cable carries the DC supply and Change-over relay contact signals. The DC
Positive supply should be connected to an ignition switched power source and be protected
by a 5A fuse.
A 4 core, M12 cable is supplied to connect the Series 1-L Control Unit to the Angle Sensor.
Different lengths of cable, or extension cables are available as required on any particular
machine. The cable should be protected from physical damage during machine operation.
3.2
Angle Sensor
The sensor monitors the angle of an imaginary line drawn between the two articulation
points of the boom. For the best operation the sensor should be installed with the long edge
parallel to this imaginary line. Position and offset from the imaginary line should achieve the
best location taking factors such as cable runs and protection into consideration.
The sensor is provided with a mounting bracket that should be welded to the boom and
painted to the boom colour.
A green LED on the Angle Sensor flashes when it is working correctly. An M12 cable then
runs from the Angle Sensor to the pressure sensor M12 connector.
