RT9150E OPERATOR MANUALOPERATING CONTROLS AND PROCEDURES

When Input mode is activated:

• To the right: increases the value

Values

• To the left: reduces the value

Slow turning changes the value slowly. Fast turning changes the value fast. 11

RCL shutdown

• On: Machine Shutdown, buzzer sounds

Degree of utilisation about 100% or an error exists.

• Off: No shutdown

The lamp (1) lights up.

In the Rigging mode submenu: Press button once, rigging mode monitoring submenu opens.

Refer to RCL Shutdown, page 3-72. 12

Input confirmation

In the Rigging mode monitoring submenu:

Press button once, rigging mode is accepted, Monitoring submenu opens, lamp (1) goes out.

RCL Early Warning

Refer to Figure3-69

RCL Shutdown

There are different types of RCL shutdowns:

• Shutdown due to overload,

• Shutdown due to an error message, refer to the Error Submenu, page 3-101.

When operating with a hydraulic luffing jib, an overload condition can develop when changing the angle of the jib. When this occurs the lowering of the hydraulic luffing jib is stopped by the RCL.

Shutdown Due to Overload

Refer to Figure3-70

If about 90% of the maximum permissible load is exceeded, an RCL early warning is given:

• An intermittent buzzer tone sounds.

After five seconds, you can switch off the buzzer tone using the CE button (1).

• The lamp (2) lights up.

• The display (3) shows the current percent of maximum load, e.g. 91%; the bar is yellow.

NOTE: If the current crane movements continue to be carried out in the same direction, there is an RCL shutdown.

If about 100% of the maximum permissible load is exceeded, shutdown occurs due to overload:

• All crane movements which increase the load moment are switched off.

• The hydraulic luffing jib will not be allowed to lower— increase the angle.

• A continuous buzzer tone sounds.

After five seconds, you can switch off the buzzer tone using the CE button (4).

• Lamps (5) and (6) light up.

• The display (3) shows the current percent of maximum load, e.g. 100%; the bar is red.

• The value on display (2) is equal to or greater than the value on display (1).

Canceling a Shutdown

1. Turn off the buzzer tone if necessary.

2. Leave the shutdown range by performing one of the operations listed in the following table—in most cases the permitted movement will be the opposite of the switched off movement:

Switched off crane movements Permitted crane movements

Lifting loads

Lowering the main boom

Extending the main boom

Slewing to the left

Slewing to the right

Lowering the lattice extension

Lowering loads

Raising the main boom1

Retracting the main boom1

Slewing to the right

Slewing to the left

Raising the lattice extension

1 In some cases, the RCL also switches off these movements. In this case, leave the shutdown range through other enabled movements. If this is not possible, set down the load.

If you have left the shutdown range, the lamp (6) goes out. After pressing the button CE the crane movements are enabled.

RCL Override

If the RCL is overridden, the crane operation is not monitored and the switched off crane movements are enabled again.

Warning

Tipping and/or Machine Damage Hazard!

You may only override the RCL if it becomes absolutely necessary in the event of an emergency. This is to put the crane into a safe condition in the event of a malfunction. In this case, do not perform any movements that would increase the load moment.

Overriding the RCL

Refer to Figure3-71

FIGURE3-71

1. Insert the key into the key-operated switch below the ECOS console, RCL Override Switch (Non-CE Certified Cranes), page 3-7.

2. Turn the key clockwise and hold it in this position (A).

3. The display (1) shows the error message 8.0.22.

Canceling the Override

1. Let go of the key (B).

2. Remove the key.

3. Press the CE button once, the error message is acknowledged.

Anti Two-Block Switch Override

Refer to Figure3-72

Published 2-18-2016, Control # 614-00 Grove

When overridden, the shutdown of the anti two-block switch is cancelled and the crane operation is no longer completely monitored.

You can only override the anti two-block switch together with the RCL.

Warning

Two-Blocking Hazard!

The anti-two-block override switch should be used with caution. The operator must ensure two-blocking doesn’t occur when the override is activated.

If the anti-two-block switch is overridden, crane operation is no longer completely monitored; when hoisting the anti two-block switch weight, crane movement will be stopped once. After moving the control lever again, the crane movement is then enabled and the anti-two-block switch is overridden.

The lamp (1) lights up if the anti two-block switch has been triggered.

At the same time, all movement which increases the load moment are switched off; lifting, lowering, extending and adjusting the boom extension.

To cancel the shutdown, leave the shutdown range by performing a different crane movement or by setting down the load.

To override the lift limit switch:

1. Insert the key into the key-operated switch (2).

2. Turn the key counter-clockwise and hold.

The anti two-block switch and the RCL are overridden until you let go of the key.

If the anti two-block switch is triggered now, crane movement is stopped once and the lamp (1) flashes.

Crane movement is enabled again if you bring the control lever to zero position and then move it again.

Crane movement will not be stopped again.

The lamp (1) goes out:

- if you let go of the key-operated switch (override cancelled) or

- if you leave the shutdown range.
