Primary Boom Angle Sensor

A properly functioning primary boom angle sensor
(PBAS) is essential to safe machine operation. The
primary boom angle sensor is used to limit the
angle of the primary boom relative to ground. The
ECM at the ground controls (TCON) monitors the
position and angle of the primary boom using the
signal from PBAS. The PBAS signal is used to
control the ramping of the primary boom as well as
velocity control, limiting the speed of the primary
boom to 1.3 feet / 0.4 meters per second.
