3.1.3Control unit

M The function of the push buttons marked with (M) are memorized when the excavator is stopped. This means that, when turning on the excavator, the controlled function recovers the previous state (on-off, 1-2, I-C, ...) before the machine had been turned off

S10 - Driving light / Equipment headlight

Press the switch.

Driving light is activated. LED 1 in the switch illuminates.

Press switch again. Driving light is deactivated. LED 1 in the switch goes out. Equipment headlight is activated. LED 2 in the switch illuminates.

Press switch again.

Driving light and equipment headlight are switched on. LEDs 1 and 2 in the switch illuminate.

Press switch again.

Driving light and equipment headlight are switched off. LEDs 1 and 2 in the switch go out.

S11 Windshield washer

Press the touch and keep it depressed: washer fluid is sprayed onto the windshield, the windshield wiper runs continuously.

Release the touch: the washer fluid spraying is stopped, the windshield wiper will stop after approx 3 seconds.

S14 Windshield wiper

Press the touch: the windshield wiper is turned on in intermittent mode, LED I in the touch illuminates.

Press the touch again: the windshield wiper is turned on in continuous, LED C in the touch illuminates and LED I goes out.

Press the touch again: the windshield wiper is switched off, LED C in the touch goes out.

The touch S14 also allows to adjust the pause time for the intermittent mode of the windshield wiper: press the touch to select the intermittent mode and keep the touch depressed, after a few seconds the LED I starts blinking rapidly, release the touch as soon as the blinking duration has reached the desired pause time (settings from 2 - 9 seconds).

S17 Preselection of swing brake operating mode

Press the touch S17 the red LED beside the touch is lighting. the swing brake is applied.

Press the touch S17 again.

1st case: when there is no positioning brake or when there is a positioning brake until BBT software version 4.58. the red LED beside the touch goes out. The swing gear brake is in automatic operating mode : the swing brake releases as soon as a swing hydraulic control is actuated.

the swing brake is applied as soon as the uppercarriage speed gets lower than a limit value and no swing hydraulic control is actuated.

2nd case: when there is a positioning brake, from BBT software version 4.58.1. the red LED beside the touch goes out. the swing brake releases.

S18 Overload warning device (optional equipment)

Press the touch: LED in the touch illuminates, the overload warning device is activated.

Press the touch again: LED in the touch goes out, the overload warning device is deactivated.

If no overload warning device is installed or if it is not correctly initialized on the machine: the indicator symbol "No overload warning device recognized" will appear on the monitoring display at warning device activation.

S19 Rotating device (optional equipment)

The rotating device is an additional hydraulic circuit necessary to drive some specific equipments (such as rotating grapple, rotating bucket, rotating stick, quick change coupling, ...).

Press the touch: LED in the touch illuminates, the control circuit for the rotating device is activated. Now the special equipment (as an ex. the rotating grapple) can be actuated using the push buttons S5L and S5R in the handle of the left joystick unit.

Press the touch again: LED in the touch goes out, the control circuit for the rotating device is deactivated. The actuation of the special equipment via S5L and S5R is no longer possible.

S20 Engine low idle automatic

Press the touch: LED in the touch illuminates, The low idle automatic is activated.

Press the touch again: LED in the touch goes out, The low idle automatic is deactivated.

Adjustment of the time lag for low idle automatic

The time lag between the return to neutral of all joysticks and pedals and the automatic reduction of the engine RPM to low idle can be adjusted using the touch S20 as follows: press the touch to activate the low idle automatic and keep the touch depressed. after a few seconds the LED starts blinking rapidly, release the touch as soon as the blinking duration has reached the desired time lag for low idle automatic (settings from 2 - 9 seconds).

S21 Travel speed increase

Press the touch: LED 1 in the touch illuminates, the automatic shifting from normal to increased travel speed is activated. During travel, the oil motors mounted to the travel gears now change automatically from normal speed to increased speed each time the terrain conditions allow it, and inversely, they return to normal travel speed when ground conditions become difficult.

Press the touch again: LED 1 in the touch goes out, the automatic shifting between normal and increased travel speed is deactivated. The travel motors remain permanently in the normal travel speed position.

S22 Auxiliary floodlights (optional equipment)

Press the touch: LED in the touch illuminates, the auxiliary floodlights are turned on.

Press the touch again: LED in the touch goes out, the auxiliary floodlights are switched off.

S36 No function

S41 Rotating beacon (optional equipment)

Press the touch: LED in the touch illuminates, the rotating beacon is turned on.

Press the touch again: LED in the touch goes out, the rotating beacon is switched off.
