5 ANGLE THEORY
The System measures the angle of the main boom of the machine with an angle sensor. The angle
sensor is contained within the angle sensor box (Radio A2B option) or within the Cable Reel
(Hardwired A2B option) located on the left side of the main boom.
Block Diagram
The signal runs from the angle sensor to the Can-Bus converter board, both located in the angle
sensor box. From there, it travels as digital information on the CAN-Bus to the pressure sensor, which
acts as a T-connector to the main CAN-Bus running to the console/central unit.
So, what do you do when you are having a problem with your angle read-out?
Start by verifying the angle display. Refer to the section “Troubleshooting A Sensor Problem Using
The Display” to call up the sensor signal on your console display. The CAN-Bus is digital and as such
will either transmit the signal correctly or not at all. If your readings are off, you have to determine
what is causing the problem. Start by opening the angle sensor box and locate the angle sensor (top)
and the CAN-Bus converter board (bottom):
