3.1.4Control unit

1 - Display

The display

–Indicates the nominal speed of the diesel engine in ten steps.

–Indicates the total operating hours and the daily operating hours.

–Indicates the error codes.

–Can be used to call up machine data.

–Can be used to adjust and manage functions (operator menu).

The display is automatically activated when the vehicle ignition is switched on, completes a self-test and then shows the start screen.

2 - Speed

Indicates the nominal speed of the diesel engine in ten steps.

3 - Speed minus (-) key

Reduces the nominal speed of the diesel engine.

4 - Idle automatic key

The idle automatic function automatically reduces the engine speed without actuation of the joystick or the travel pedal. This helps save fuel and reduces the noise level. By touching the joystick or the pedals, the engine speed returns to the initial level.

5 - Speed plus (+) key

Increases the nominal speed of the diesel engine.

6 - Indicator light of direction indicator

The light flashes if the direction indicator is activated or the warning light system is on.

14 - Indicator light of oscillating-axle locking system

This light is on if the oscillating axle is locked.

15 - Indicator light of engine oil pressure

This light is on if, during operation, the engine oil pressure drops below a set limit value. This signal is accompanied by a warning sound.

When this light is on, immediately switch the engine to its lower idle speed and shut it down.

16 - Indicator light of oscillating axle automatic

This light is on if the oscillating axle automatic is switched on and the oscillating axle is automatically locked when the working brake is actuated.

17 - Indicator light for air filter contamination copyright by

This light is on if the air filter is contaminated.

Immediately switch the diesel engine to its lower idle speed and let it run idle for another approx. 30seconds. Switch off the diesel engine. Replace the filter element, if required.

18

- Indicator light of parking brake

This light is on when the parking brake (S16) is applied.

19

- Indicator light for coolant level

This light is on, if the coolant level drops below a certain level. When this light is on, immediately switch the engine to its lower idle speed and shut it down.

Check the system for leaks and repair them, if necessary. Add coolant.

Note!

The indicator light for coolant level is an additional indicating device preventing damage caused by excessive loss of coolant (e.g. due to hose break). The machine operator or maintenance personnel must however still regularly inspect the coolant level in the expansion tank.

20 - Indicator light of

Hydraulic Oil Temperature

This light is on, if the hydraulic oil temperature in the tank exceeds 100°C.

When this light is on, immediately switch the engine to its lower idle speed and shut it down.

Identify the cause of the problem (e.g. dirty radiator) and eliminate it.

21

- Indicator light of fuel pre-filter

This light indicates that there is excessive water in the fuel pre-filter.

Remove the water from the fuel pre-filter.

22

- Indicator light of overload warning indicator

This light is on, if the overload warning system (S18) is activated and the maximum permissible load of the machine is reached. This signal is accompanied by a warning sound.

Avoid increasing the load. Reduce the load of the machine.

23 - Indicator light of quick-change

Adapter

This light is on during the release procedure or if the lock pins are retracted.

24 -

Indicator light for accumulator charge pressure (working brake)

This light indicates that the accumulator charge pressure is too low The working brake may not be working properly.

Halt the machine.

Set the engine to low idle gear. Move the safety lever up.

Check the brake system and repair it, if necessary.

25 - Indicator light for battery charging

This light is on when the ignition is started, and is off as soon as the diesel engine is running.

During engine operation, the indicator light is on, if the V-belt of the alternator or the electrical charging system is defective. Set the engine to low idle gear.

Let engine run in low idle for about 30 seconds. Switch off the diesel engine. Repair the defect.

26 - ENTER key

Press this key to confirm your entry (see chapter "Display").

27 - RIGHT key

Moves the cursor in the display to the right (see chapter "Display"). Press this key to exit the menu.

28 - DOWN key

Moves the cursor in the display down (see chapter "Display).

29 - UP key

Moves the cursor in the display up (see chapter "Display).

Tab. 3-1 Explanation of submenus

3.1.5.1Description of the submenus Tool Option

This menu is used to select pre-set pressure and flow reductions to the working tools (activation of foot pedals, e.g. for hydraulic hammer or grapple).

Prior to using the working tools, the correct option for the working tool must be selected at the display.

Caution!

Incorrect pressure or flow reduction settings may result in damage to the working tool (e.g. hydraulic hammer) or impair its functions (e.g. mill). Select the correct option before using the working tools.

Menu navigation:

Move the cursor down with the DOWN key, until the desired working tool is selected (options 1 to 10) and then press the ENTER key. The working tool is selected.

Note!

On request, LIEBHERR and the customer service department will pre--set the desired options and label them with the names of the associated tools, e.g. "hammer" or "grapple".

Contact us to have the menu for each working tool set up.

This menu allows you to adjust the flow reduction (SF-Flow) for the Super Finish function. With the Super Finish function, the movement of the attachment can be slowed down, so that tasks can be carried out with greater precision.

Adjustment range: 0% (max. flow reduction) to 100% (no reduction).

Menu navigation:

Use the UP and DOWN keys to select the desired reduction. Press the RIGHT key to confirm your selection. The SF-Flow settings are selected.

Actuate the SF switch on the A console. The respective menu is shown on the display.

In this menu, you can adjust the sensitivity of the slewing gear. These settings determine the accuracy with which the uppercarriage can be positioned. The acceleration of the uppercarriage is determined by the distance by which the joystick handle is moved and the set sensitivity of the drive. The swivelling movement can be set to slow or fast (direct propulsion).

The set sensitivity remains active when the menu is closed and cannot be deactivated or activated without accessing the menu again.

Adjustment range: 0 (very slow) to 100 (fast).

Menu navigation:

Use the UP and DOWN keys to select the desired movement speed. Press the RIGHT key to confirm your selection. The desired torque slew is now set.
