Left and right joystick switches
The Grade Control system supports the optional joystick handles with modulation and push-button switches. The modulation and push-button switches allow the operator to interact with the system to perform the following functions:
Set and clear benchmark (push button)
Adjust target depth and target slope (modulation switches)
Perform touch point function or accept laser (push button)LC450 Laser Catcher
Illustration 8 g01894554
Laser catcher
The laser catcher is a sensor that has a laser detection window that communicates laser strike information to the system when a laser signal is detected by the sensor. This information is used by the system to compensate for machine elevation changes as the machine settles or is relocated across the worksite. The laser catcher is mounted on the left side of the stick of the machine. The laser catcher communicates over the CAN.Refer to Systems Operation, Troubleshooting, Testing and Adjusting, "Connector Contact Description" for the connector information.Pitch/Roll Sensor

Sensor installed on frame
The Grade Control system utilizes a pitch/roll sensor to measure the front-to-back and side-to-side orientation of the machine chassis. These measurements are used by the ECM to calculate accurately the bucket tip position for guidance to the target elevation. The sensor is located on the upper frame next to the cab, below the boom pivot pin. The pitch/roll sensor communicates over the CAN.ECM
Illustration 11 g02378057
Machine ECM
The sensors continuously communicate the position of the stick, boom, and the bucket to the ECM. The ECM uses the sensor inputs along with the machine and bucket dimensions to calculate the bucket tip position. Bucket tip elevation data and system status data is sent from the ECM to the display to provide guidance to the operator.Refer to Systems Operation, Troubleshooting, Testing and Adjusting, "Connector Contact Description" for the connector information.Monitor Display
Illustration 12 g02358256
Monitor display
The monitor display provides a graphical user interface for the Grade Control system. The display shows information such as depth to grade, bench mark status, bucket profile view. With this information, the operator can operate the machine efficiently and achieve the desired grade. The monitor display also includes user interfaces to configure machine and work tool dimensions as well as other system options.GNSS Receiver Mast Bracket

Note: GNSS Receiver mast bracket location can vary depending on model and vintage. Older E-Series 320 - E-Series 349 models that have not been reworked have rear counterweight GNSS Receiver mast brackets. Current and reworked E-Series 320 - E-Series 349 models have forward GNSS Receiver mast brackets.Brackets fixed to the machine, provide a weld-free upgrade from Cat® Grade Control Depth and Slope to AccuGrade. Reference AccuGrade documents for further information on machines upgraded to AccuGrade.Note: The factory installed brackets for the GNSS Receiver Mast have changed locations. Older E-Series machines have the brackets on the counterweight where as recent E-Series and
