This diagnostic code is associated with the calibration of the lift valve and the tilt valve. The "Display" requested movement, but the valve took too long to get to the desired position.
System Response:
When this diagnostic code is active the calibration procedure is terminated.
Test Step 1. CHECK THE LASER TRANSMITTER
- Verify that the laser transmitter setup is stable.
Refer to the Operation and Maintenance Manual, "Setup Procedures" in order to ensure the laser transmitter setup is stable. Repeat the valve calibration.
Expected Result:
A successful calibration causes the diagnostic code to become inactive.
Results:
- YES - A successful calibration causes the diagnostic code to become inactive. Return the machine to normal operation. Stop.
- NO - Calibration is not successful. The diagnostic code is still active. Proceed to Test Step 2 for further troubleshooting.
Test Step 2. CHECK OPERATION OF THE VALVE
- Use the "Test Valves" menu in order to determine if the valve is working correctly.
Refer to Operation and Maintenance Manual, "Modes of Operation-Configuration" for more information about the "Test Valves" menu.
- Inside the "Diagnostics" menu, toggle either the "right mast elevation/menu scroll" switch or the "left mast elevation/menu scroll" switch until "Test Valves" is highlighted.
- Press the OK/right reset button to select this item. A screen similar to the following appears:
