1.4.4 Entering limiting values for maximum slewing angles

This section presupposes that the values for the maximum slewing angles are unknown and therefore describes the input by starting the switching points. For this, the following prerequisites must be fulfilled: – manual entry is switched off; à Entering limiting values manually, p. 1 - 17, – slewing angle monitoring is switched off; à Switching monitoring off, p. 1 - 20.

HIf the monitoring is switched on, you cannot start any larger limiting value as the monitoring would switch off crane movement. If manual entry is switched on, you cannot adopt the values for the currently started switching point.

HYou can cancel the following entry at any time by pressing the Exit submenu/ entry mode (ö) button once. The red bar under the selected entry goes out.

Displays in submenu Working Range Limiter

Definition: A displayed 0° angle means that the superstructure is turned backwards (is therefore in the 0° to the rear working position. A complete rotation out of this working position is separated into two semicircles for the display: – angles in right semicircle are displayed positively (0° to +180,0°), – angles in left semicircle are displayed negatively (0° to –179,9°).

In the Maximum/current slewing angle display (2), the middle value (surrounded in blue) displays the angle for the current position of the superstructure. The upper value (surrounded in red) displays the set value for slewing angle A. The lower value (surrounded in red) displays the set value for slewing angle B.

• To enter slewing angle A or B, press the button next to the Maximum slewing angle entry submenu symbol (1) once.

The Maximum slewing angle entry submenu opens.

Presentation of slewing angles In the Maximum slewing angle entry submenu, the entered slewing angles A and B are presented pictorially in the Limited slewing angle display.

The current boom position is shown with a cross (1) and constantly changes when the superstructure rotates.

Both slewing angles A and B are displayed directly and represent the limits of the permissible slewing range.

The permissible slewing range is the angle from A clockwise to B (approx. 270° in the diagram).

Slewing angle A is the slewing movement limit within the permissible slewing range to the left.

Slewing angle B is the slewing movement limit within the permissible slewing range to the right.

GRisk of accident due to defectively set slewing angle. Observe the definitions of slewing angles A and B when starting the switching points. – When the value for slewing angle A is adopted, the switching point must always be located to the left next to the boom. – When the value for slewing angle B is adopted, the switching point must always be located to the right next to the boom. If you swap the values for slewing angles A and B, the switching points are then located within the permissible slewing range.

Entering the slewing angle In the Maximum slewing angle entry submenu, you can enter the values for slewing angles A and B individually one after the other.

• Select the slewing angle to be entered. For this, press the button next to the Select slewing angle A (2) or Select slewing angle B symbol (3). A red bar appears under the selected display (e.g. Maximum/current slewing angle A (1)).

Rotate the superstructure to just in front of the switching point: – If you have selected slewing angle A, the switching point must be located on the left next to the boom head (cross 4). – If you have selected slewing angle B, the switching point must be located on the right next to the boom head.

In the selected display (e.g. Maximum/current slewing angle A display (1), the lower value (surrounded in blue) displays the angle for the current position of the superstructure.

• Adopt the lower value as the limiting value by pressing the Confirm entry button (Ö) once.

The upper value in the display (surrounded in red) now shows the newly set slewing angle (e.g. slewing angle A = –140°).

• Enter the required values for slewing angles

A and B.

• Change to the Working Range Limiter submenu (1 x ö). • Switch on the slewing angle monitoring; à Switching monitoring on, p. 1 - 19.

HWhen the values for slewing angles A and B are known, you can also enter the values into the selected displays manually and adopt them as a limiting value; à Entering limiting values manually, p. 1 - 17.
