Drive the vehicle forwards to test the radar signal. The waveform below shows the vehicle setting off from stationary, moving at a constant speed before returning to stationary. • Blue trace:- Feed. This remains constant from key on. • Red trace:- Signal. From the start of the trace it can be seen that the vehicle is stationary as the voltage remains constant. As the vehicle begins to move the radar gives an on off reading. The vehicle uses this signal to calculate the speed by measuring the difference in the frequency of the signal transmitted to the frequency of the signal received. • Brown trace:- Radar present. This remains constant from key on, indicating that the radar is present. • Green trace:- Earth. This remains constant from key on, indicating the earth signal from the radar.

Electrical systems - Parking brake electrical system

Electronic park lock actuator/controller - Dynamic description The Electronic Park Lock (EPL) system works in parallel with the mechanical parking brake which remains fitted as the homologated parking and secondary brake device.

Shuttle lever positions (as viewed from the left-hand cab steps) 1 (F) 4

Forward (momentary position) Rest position (stable position)

3 (F) 6

Reverse (momentary position) Park position / EPL engaged (latched position)

To engage the EPL, the shuttle lever has to be moved into the park position, i.e. down and forward - position (6). For CVT, the EPL will also automatically engage if the vehicle is stationary with the engine running and the driveline is engaged (power-zero mode) for more than 45 seconds, EPL will be applied and then the driveline will be disengaged. The EPL can be disengaged in one of three ways: 1. Auto Take Off (ATO) - Move the shuttle lever into drive position 1 or 3. Driveline will be engaged and EPL released, the take off management will modulate the transmission and EPL to prevent free-wheeling. 2. Inching - Move the shuttle lever into drive position 1 or 3 with the clutch depressed, the EPL will disengage and the vehicle will stay in neutral until the clutch is released. NOTE: Whilst in neutral, the vehicle will be able to free wheel. 3. Disengage EPL - To disengage the EPL, move the shuttle lever into position (4) while keeping the brakes as well as the neutral button on the side of the shuttle lever depressed. NOTE: If the brakes are released at this point the vehicle will free wheel. There are two lamps on the instrument cluster that will illuminate in association with the EPL.

BAIL10CVT457AVA

The park indication lamp (1) has a dual functionality, indicating that either the EPL or the parking brake is engaged. During keystart on, the lamp flashing indicates the EPL is releasing. If, at keystart off, if the lamp flashes for 10s accompanied by a buzzer, it indicates that the EPL and parking brake are not applied.

Electrical systems - Parking brake electrical system

The EPL status lamp (2) is used to indicate a malfunction of the EPL. This could indicate a fault with EPL or the inhibition of the EPL auto apply at the following keystart off.

EPL Auto Apply At keystart off the EPL is automatically engaged. If there is a delay of more than two seconds before the EPL is fully applied, a buzzer will sound and the park indication lamp will flash until the EPL is fully engaged. After keystart off, no movement of the shuttle lever will release the EPL.

EPL Apply Inhibit at Key Off If the vehicle needs to be towed it is possible to prevent the EPL from engaging at key off. Hold the shuttle lever in position (5), while pressing both brake pedals for at least three seconds. The cluster will illuminate the EPL failure lamp, see figure 3.

BAIL10CVT458AVA

Figure 3 To activate the EPL inhibit function, keystart off while still depressing the brake pedals and holding the shuttle lever. If either the brake pedals or shuttle lever are released before keystart off, the process is cancelled and the EPL will engage normally. NOTE: In the event of EPL already engaged at keystart off, it wouldn’t be released if the auto apply inhibit had been chosen.

NOT_INIT Procedure In the event of first configuration of EPL, after a power failure or after a manual release, the EPL may be, once the supply voltage is set again, in an undefined state called NOT_INIT and an icon will be displayed on the instrument cluster, see figure 4.

Figure 5 Once the EPL is fully applied, the procedure will be complete and full functionality will be restored.

Trailer Brakes Trailer brakes are managed by the EPL in the same way as they are with the parking brake. If either the EPL or parking brake are applied , the trailer brakes are applied.

Release in the Event of Power Failure In case of a failure & EPL cannot be released electronically, the EPL can be manually released using a winder mechanism which is clipped to the parking brake lever in the cab. Remove the tool from the retaining clips. Locate the EPL on the back of the cab and remove the two rubber protection caps one external and one internal. Insert the manual release tool and slightly rotating it clockwise/couterclockwise make sure that the internal shaft slides into the receptacle on the tool end. Rotate the small handle on the other end of the tool clockwise to release EPL. Stop when the load on the handle raises slightly; a fully applied EPL will take about 150 revolutions to release. In an emergency, it is possible to drive the tractor against the park brake. It is recommended that this is only for emergency use and manual release should be used when possible, for this reason, the vehicle speed will be limited to 2 km/h in this situation.

Test notes • The solenoid currents may vary depending on the drop speed selected and the weight on the hydraulics • The fast raise and lower buttons should be used during the test with pre-determined minimum and maximum points set depending on whether an implement is connected to the hydraulics. • Traces may vary depending on the raise and lower speed settings.

Waveform notes The waveform above shows the current acting on the raise and lower solenoids of the EDC valve and the EDC potentiometer voltage while the hydraulics are raised, held at the max point and lowered. The green line shows the voltage reading from the potentiometer, it is useful in providing a visual representation of the position of the hydraulics. The potentiometer voltage increases as the hydraulic voltage rises and falls as the hydraulics lower. This is useful when seeing what the raise and lower solenoids are doing in relation to the position of the hydraulics. The blue line shows the current being drawn from the raise solenoid, it shows that when the command to raise the hydraulics is given the solenoid energises, as the hydraulics near the top of their travel, the current falls away to give a smooth declaration. When the hydraulics have reached the top of their travel, the solenoid is then turned off and the position of the hydraulics is held by the check valve. When the command to lower the hydraulics is given, the lower solenoid is activated. As the hydraulics reach the bottom of their travel, the current falls away to give the hydraulics a smooth stop. It is important to note that the line from the potentiometer is linear during both the raise and lower operations and contains no erratic jumps or uneven raising or lowering. NOTE: For this test, maximum height was set at 10 and minimum height was set at 0. There was no mass on the hydraulics when this test was carried out.
