Control and operation

Note

A light sensor built in to the top left of the monitoring screen adapts the illumination on the main screen to the brightness of the environment. The adaptation takes place from the saved brightness value. Illumination will be automatically reduced in conditions of low environmental brightness and inversely.

To change the brightness and the contrast setting to the initial setting: Turn off the ignition.

Press and hold the Up and Down keys simultaneously. Turn on the ignition again.

After completion of the automatic display check release the both keys.: the settings for the brightness and for the contrast of the LCD screen retrieve their initial values set at machine delivery.

3.1.5Main screen

The main screen appears when the machine has been switched on and remains on display until the screen is changed over to the menu selection screen using the Menu key.

EC Error codes of electrical errors SY Symbols of operating faults, clock

INF Information symbols TI Display of hour meters, flow limitations, ...

Constitution of the main screen

SY field

The upper field of the screen shows the warning symbols for the actual operating faults and also the clock.

Should more than two symbols be shown, so the clock is not displayed any more and up to four symbols can be shown at the same time in the field SY.

If more than 4 symbols must be shown, then every 10 seconds, the symbols move to the left by one symbol.

See the list of the possible symbols in section "Warning symbols in the SY field", fur- ther in this chapter.

EC field

The EC window displays the error codes for electrical faults which occur in the excavator's electronics system (line errors, sensor errors etc.). A maximum of 7error codes are displayed simultaneously. If there are more than these 7errors present, an arrow which points to where the other error codes are located will be displayed next to the error code window.

Press the Up or Down button. The error code list is shifted in the selected direction.

See the complete list of the error codes in section "Error codes charts", in chapter 4.

INF field

The INF field displays temporary information in graphic form. If more than 3symbols are to be displayed, the symbols will shift one symbol to the left approx. every 10seconds.

The information is displayed in graphic or text form and indicates specific operating states on the machine (also see the section "Information symbols in the INF field", further in this chapter).

TI field

The machine operating hours and the daily operating hours counter are displayed in this field at the bottom right of the screen. During the start-up phase, the operator will be alerted about a possible up-coming service time, by a graphic symbol and an hour indication displayed instead of the machine hour-meter during about 8 seconds.

The symbol ® is displayed when an external flow limitation is activated (see the description of the menu "Info In/Outputs", further in this chapter).

The symbol " " indicates that no external flow limitation is actually activated. But an internal flow limitation (travel, swing,...) may be activated.

In this field can also be indicated the denomination (for example HM2000) of the option which is actually assigned to the external flow limitation input I1 (see the description of the menu "Set option", further in this chapter).

Control of the screen at error recognition

In case a new operating fault displayed in the field SY is recognized, the presentation will return to the main screen, and the relevant symbol is displayed. Depending on the fault (level of urgency), the buzzer will sound either continuously or in short consecutive bursts. At the same time the symbol "acknowledge error" will be displayed in the INF field.

Danger!

If the displayed fault is not remedied immediately, this could lead to persons sustaining injury or the machine being damaged. Immediately remedy the occured error or get it remedied. Press the Back key.

The error will be acknowledged, this means that the buzzer signal alerting to the upcoming of this fault is stopped.

Warning symbols in the SY field

A) Warning symbols for operating faults

Each of the following symbols will be assigned an error code in the form “E5xx”. When the trouble is occuring, the corresponding symbol is displayed in the field SY of the screen. The error code will not be displayed in the field EC too, but the occured error will be memorized under this error code in the error list.

E504 – Low hydraulic oil level

This symbol appears if the oil level in the hydraulic tank drops below the minimum level.

The buzzer sounds simultaneously. Switch the motor off as quickly as possible. Find the leak.

Depressurize the hydraulic tank.

Carry out repairs.

Only refill the hydraulic oil using the return-line filter.

E505 – Hydraulic oil overheat

This symbol appears if the hydraulic oil temperature in the tank exceeds 99°C. Switch the motor off after a few seconds. Find out and remedy the trouble (radiator dirty etc.).

E506 – Splitterbox oil overheat

This symbol appears if the oil temperature in the splitterbox exceeds 100°C. Switch the motor off after a few seconds.

Localise and rectify the error.

E511 – High voltage of batteries

This symbol appears if the momentaneous voltage of the batteries exceeds 30volts for at least 0.5seconds.

E548 – Overheating of the stator windings of the electric motor

This symbol lights up to alert that the maximum admissible temperature in the stator windings has been reached.

If this temperature increases some more, the electric motor will be shut down automatically.

E550 - Overheating of the bearings of the electric motor

This symbol lights up to alert that the maximum admissible temperature for the bearings of the electric motor has been reached.

Have in this case the bearings verified (Grease quantity, grease quality, vibration level, ...) as indicated in the attached maintenance manual of the manufacturer of the motor.

B) Warning symbols for special operating states und system errors

In addition to the above mentioned operating faults, also the symbols of the list below may appear in the SY field of the screen to warn the operator of the occurence of particular operating sequences or of some particular system errors.

Quick change adapter (optional equipment)

This symbol appears during the unlocking procedure or when the locking pins of the quick change adapter are not completely out. No error code is corresponding to this symbol.

Information symbols in the INF field

Error in measurement of hydraulic pressure

This symbol informs of the emergence of a trouble in the circuit for measurement of the servo control pressures.

As a result of the incorrect pressure measurement(s), all the functions of the power regulation of the concerned movement(s) can no longer be ensured, these movements are controlled in a downgraded mode.

At the same time the related error codes will be displayed in the EC field of the main screen to specify which are the incriminated movements and pressure transmitters.

•error code E150, E151: stick movement (pressure transmitter B159)

•error code E153, E154: boom movement (pressure transmitter B160)

•error code E156, E157: swing movement (pressure transmitter B167)

•error code E159, E160: travel movement (pressure transmitter B162)

•error code E162, E163: bucket movement (pressure transmitter B163)

See also the error codes chart in chapter 4 "malfunctions".

Service due

This symbol indicates that the moment for carrying out the next recurring service work has nearly arrived. During this span of time, and each time when the electrical system of the machine is turned on, this symbol and the hours for the next service falling due will be displayed for approx. 10 seconds in place of the current operating hours.

Get the the service work carried out within the prescribed delay,or report the falling due to your supervisor.

The symbol will go out after the execution of the programmed service work has been confirmed, see the menu "set service" thereafter.

Acknowledge error

This symbol appears if an operating fault of the machine (E5xx type error code) has occurred and the buzzer sounds simultaneously.

It informs the operator that he can, after having recognised the occured fault, press the back key to stop the buzzer.

“Increased care required” - servo-control circuit in safety mode

This symbol alerts the operator that the servo-pressure circuits have been turned into safety mode (switch S73 is tilted in safety position).

Swing brake not operative

This symbol alerts the operator that the swing brake control circuit is out of function due to the turning into safety mode of the servo-control via switch S73.

Servo control operation changed

This symbol appears if switch S73 is tilted into the safety mode position.
