© 2-1 System inspection with DAVIE XD EMAS DAVIE XD diagnostics manual 5 2. SYSTEM INSPECTION WITH DAVIE XD 2.1 GENERAL When changes are made to the EMAS system or when it is opened, the system must be calibrated. 2.2 "CALIBRATION" MENU The "Calibration" menu is divided into several tests: - Air test - Bleeding - Releasing the pressure - Hydraulic test - Electric test - Complete calibration Air test the EMAS system. If so, the EMAS system must be bled. Bleeding air is found in the EMAS system, the trailing axle will be steered back and forth and there is a possibility of releasing air. Afterwards another air test will be carried out to check whether there is still air in the system. If air is still present, the above routine is repeated. Releasing the pressure connected to the centring circuit need to be removed, the pressure in the centring circuit must be released. When this test is selected, the pressure in the centring circuit will be released by opening and closing various valves. Hydraulic test With this test it is checked whether the various valves are properly steered and/or the system lines are properly connected. Furthermore, the central position of the steering cylinder is also calibrated. |
