Functions of and How to Use User Mode (TS-75M-1)

Mode Structure

The AML device has three modes and the AML functions are allotted for these models.

2. Maintenance Mode:

Used to make functional checks of the AML. Refer to the "ADJUSTMENT AND MAINTENANCE" section.

3. Adjustment Mode: Used to make detector adjustment. Refer to the "ADJUSTMENT AND MAINTENANCE" section.

1. User Mode:

Used to indicate moment load factor or to perform AML pre-operational inspection (Normally used).

In normal use, turn ON the protect switch mounted on the adjustment window on the top of the AML.

The AML will go to the user mode when the power turns ON.

The abnormality display LED lights when the AML is in abnormal conditions (to indicate that the CPU is faulty).

Configuration and Functions of the AML System

The AML system has various kinds of functions, including the following five typical functions. Based on the work conditions registered in the AML and the signals from various sensors, these functions control the crane operations.

1. Automatic stop function to prevent overloading

The AML calculates and compares the working and rated moment values and displays their ratio. When the working moment exceeds the rated moment (100% or more), failure message is shown, alarm buzzer sounds, and the crane operation toward the critical side stops.

2. Working area limit functions

When any working area limit is registered to the AML, the crane is controlled so that the crane work posture does not exceed this registered working area limit. When the crane reaches the registered limit, failure message is shown, alarm buzzer sounds, and the crane operation stops.

3. Automatic stop function to prevent overwinding

When the hook block is overwound, the hoisting-up operation of the crane is stopped.

4. Automatic stop function for the backward stability

When the backward stability control is activated, the crane operation toward critical side is stopped. Not used in this machine.

The availability of the above described automatic stop function and working area limit functions is as shown in the table below depending on the individual operation. Be careful that turning the AML emergency switch to "非常用," and the crane starter switch to "ON" will change the center warning lamp to "AML warning" state and deactivate all the above AML stop functions (the troubleshooting function of the system).

Registering Operating Conditions

Warning

Should the operational status be incorrectly registered, the crane may overturn or be damaged, leading to a serious accident. Prior to every operation, check that the registered status corresponds to the actual status of the crane.

Registration of Outrigger Condition

[NOTICE]

Register right and left outrigger condition separately on the AML. If the front and rear outrigger extension widths differ, register the smaller extension width as shown in the figure below.

The outrigger condition symbol changes from "flashing" to "being lit" to indicate that the condition has been successfully registered.

When the power supply is turned on, the on-rubber condition symbol is automatically lit.

Even after the power supply is turned off, the registered data is stored, and when the power supply is turned on again, the system is resumed with the registered operation status. However, the maximum storage period is 2 hours. If 2 hours or more have passed before the next power on, the registered data is erased. To resume the operation, register the settings all over again.

To register the outrigger condition, use the outrigger condition selector key and set key. Each time the outrigger condition selector key is pressed, the outrigger condition symbol flashes with alternate display of "Middle extension" → "Maximum extension" → "Middle extension" → "Maximum extension." After adjusting the right and left symbol display to the actual outrigger extension, press the set key.

Registration of Front Jack Condition

To register the front jack condition, use the front jack condition register switch.

1. When the front jack is used: Set the front jack condition register switch to (ON). The front jack condition symbol will light, indicating that the front jack condition has been registered.

2. When the front jack is not used: Turn the front jack condition register switch to (OFF).

Registration of Lift Status [NOTICE]

When the power supply is turned on, the boom lift is automatically selected. Even after the power supply is turned off, the registered data is stored, and when the power supply is turned on again, the system is resumed with the registered operation status. However, the maximum storage period is 2 hours. If 2 hours or more have passed before the next power on, the registered data is erased. To resume the operation, register the settings all over again.

To register the lift status, use the lift status selector key and set key.

Each time the lift status selector key is pressed, the display alternates in the sequence of "ブーム" → "シ

ングルトップ" → "ブーム" → "シングルトップ" …

After adjusting the working lift status, press the set key.

The symbol changes from "flashing" to "being lit," and the registration of the lift status is completed. The numerical value corresponding to the crane load radius display registered to the AML is displayed on the load display, rated load display, and load radius display.

Display Alteration Operation

While the display alteration key is being pressed, the contents displayed on the display panel 1 can be altered. At the same time, the indicated symbol is displayed according to the displayed contents.

[NOTICE]

The displays enclosed by square as shown in the figure change. Even if the display alteration key is pressed, the contents displayed on the actual load display, rated lifting capacity display, and load radius display will not change.

Although "0" is displayed on the jib angle display, it has no particular meaning in case of this machine.
