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
This test is used to check whether there is air in

the EMAS system.

If so, the EMAS system must be bled.

Bleeding
With this test, an air test will be carried out first. If

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
If centring circuit components or components

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
Checking the hydraulic system:

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.

Electric test
Checking the electric system:

With this test it is checked whether all sensors

and valves of the EMAS system are connected;

furthermore, the resistors of the coils are

checked.

Complete calibration
The complete calibration consists of:

-

Electric test

-

Hydraulic test

-

Air test

The sensors are calibrated in between.

This complete calibration is necessary after

virtually any work is carried out on the system.
