How to work with the Laser Receiver Manual Version: 2.00 CBox Software: v3.x.x Language: English

Goal of this document Describe the use of the laser receiver together with the iDig Touch system, after the calibration of the receiver Two possible methods: - Method 1: Laser Height unknown Note: This method is preferred because it is less sensitive to the quality of the calibration of the machine. Method 2: Laser Height known If you’re using your own laser receiver, you won't get laser catch informations on the LED display or CBox control screen, but the principle remains the same.

Two methods for the 1st laser catch Method 1: Laser Height unknown Method 2: Laser Height known

Method 1 – Laser Height unknown The rotational laser is setup at a random height somewhere on the job site The bucket tip is setup on a known height  In this case the bucket height gets linked to the laser plane, and the laser height gets calculated after the 1st laser catch

In this example the desired height is 1m below the reference point. Method 1 – Job site view ? 1m In this example the desired height is 1m below the reference point.

Method 1 – CBox screen view The laser function is available, but the 1st initial laser catch hasn’t been done yet.  Click on the laser button! Click on “Bucket Tip Height”, the symbol with the pen Note: - If no laser button is shown on the main screen, the laser receiver hasn’t been calibrated yet. - If there is more than one laser button visible on the main screen, then the initial 1st laser catch has already been done. Disable the «old» laser catch first.

Method 1 – CBox screen view FIRST, put the bucket tip on the reference point THEN, enter the desired digging depth relative to the reference point (in this example 1m) and confirm Now, catch the laser beam and click on the green checkmark Note: If the option « Autocatch » has been enabled, there is no need to click on the checkmark, but the catch gets confirmed automatically

Method 1 – CBox screen view 1st laser catch done. Bucket tip height and Laser Height are shown. In this example you’ll see that the bucket tip is actually 1m above on-grade, and that the calculated Laser Height is 1,56m. Catch again the laser beam each time the machine gets moved Change the actual bucket tip height Disable the 1st laser catch Change the Laser Height Attention, if the rotating laser gets moved, the 1st laser catch has to be disabled, and the procedure to be started again from scratch! Move the reference

Method 2 – Laser Height known The rotational laser is setup on the job site, and the elevation difference of the laser plane to the desired grade gets indicated e.g. with the help of a laser rod. The machine is located anywhere on the job site (there is no landmark or reference point within reach of the bucket tip), and the rotating laser shall be connected to the laser.  In this case the laser height gets dialed into the system, and the bucket tip height gets calculated by the system after the 1st laser catch

Method 2 – Job site view 1.56 m In this example: Reference point 0.56m ? In this example: The desired grade is 0,56m below the reference point, and the rotating laser is setup 1m higher than the reference point. This means, that the Laser Height (elevation difference of the laser plane to the desired grade) is (1m + 0,56m) 1,56m.

Method 2 – CBox screen view The laser function is available, but the 1st initial laser catch hasn’t been done yet.  Click on the laser button! Click on “Laser Height”, the symbol with the laser ray Note: - If no laser button is shown on the main screen, the laser receiver hasn’t been calibrated yet. - If there is more than one laser button visible on the main screen, then the initial 1st laser catch has already been done. Disable the «old» laser catch first.

Method 2 – CBox screen view 1.56 Enter the Laser Height: « 1,56 meters » and confirm. Now, catch the laser beam and click on the green checkmark Note: If the option « Autocatch » has been enabled, there is no need to click on the checkmark, but the catch gets confirmed automatically

Method 2 – CBox screen view 1st laser catch done. Bucket tip height and Laser Height are shown. In this example you’ll see that the bucket tip is actually 1,00m above on-grade, and that the dialed-in Laser Height is 1,56m. Catch again the laser beam each time the machine gets moved Change the actual bucket tip height Disable the 1st laser catch Change the Laser Height Attention, if the rotating laser gets moved, the 1st laser catch has to be disabled, and the procedure to be started again from scratch! Move the reference
