Control and operation

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", further 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.
