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.

After making sure that the display conforms to the actual outrigger and front jack conditions, press the register key. The outrigger state symbol (and the front jack symbol) will change from flashing to continuous lighting and the moment display, rated lifting capacity display and actual load display will

[NOTICE] When power is supplied (PTO switch is turned ON), the “on-rubber” status is automatically selected (“on-rubber” state symbol lights).

Turning the power off (PTO switch: OFF) automatically erases all the previous settings stored in memory after approximately 2 hours. To resume the operation more than 2 hours after the power has been last turned off, enter the settings all over again.

If an outrigger or the front jack is stowed after registration of outrigger status, the registered status is automatically switched to the “on-rubber” status.

In this case, register the outrigger status again before starting crane operation.

Register the outrigger state using the right or left outrigger status select key and the register key.

[NOTICE] After selecting the intended lift status, press the register key to register the status. The corresponding indicative symbols will change from flashing to lighting and the moment display, rated lifting capacity display and actual load display will return to normal display conditions, meaning that the state has been registered.

(When the jib set status is selected, the jib lift symbol will remain flashing.)

[NOTICE] The boom lift status is the default status and is automatically selected (the boom lift symbol lights up) when the power supply is turned on (the PTO switch is placed in the ON position).

Turning the power off (PTO switch: OFF) automatically erases all the previous settings stored in memory after approximately 2 hours. To resume the operation more than 2 hours after the power has been last turned off, enter the settings all over again.

Register the lift status using the lift mode select key and the register key.

Each time the lift mode select key is pressed, the mode changes in numerical sequence, from (1) to (4). The display returns to (1) if you press the switch while the status (4) is displayed on the screen. Select the status that corresponds to the actual lift status.

Functions of and How to Use User Mode (TT-300XL-1) When the power supply is turned on (i.e. PTO switch ON), the standard number of parts of line corresponding to the work condition is selected.

Selecting Number of Parts of line [NOTICE] If the registered number of parts of line is smaller than the standard number, a maximum allowable lifting load is limited, depending on the registered number. If zero(0) is registered, however, the AML performs as if the standard number were registered.

Register the number of parts of line by use of the number of parts of line select key and the register key, as follows:

System trouble (RAM trouble) System trouble (RAM trouble) System trouble (CPU trouble) System trouble (bus error) System trouble (address error) System trouble (unauthorised instruction) System trouble (privilege violation)

Situation:

All operations except boom swing are unavailable because software program cannot run normally.

Cause:

The AML’s CPU board is defective.

Action:

Replace the AML’s CPU board.

If this error has occurred, the relevant error message is displayed and the AML stops processing. (There is a continuous beep and two LEDs in the adjustment window illuminate) While the AML’s CPU board is suspected to be defective, check the inside of the AML for any abnormality such as loose connectors.

Description

Error : 3010

System trouble (A/D converter trouble)

Situation:

All operations except boom swing are unavailable due to abnormal input to the A/D converter.

Cause:

AML’s CPU board and/or analog board are defective.

Wiring for the analog defector is abnormal (short-circuit).

Action:

Replace the AML’s CPU board and/or analog board.

Check the connection (resistance) of analog detectors (one connected with AML itself).

Replacing the Clock Battery Replacing the Clock Battery

3. Attach a new battery on the CPU board by pressing the battery diagonally. (Refer to the

[NOTICE]

figure below)

When the clock battery is worn out, the adjusting values, error codes and driving history cannot be backed up (saving data at power OFF).

Also, when the error code or driving history is recorded in AML, an accurate date and time cannot be recorded.

The battery positive side must be faced up.

Two built-in clock batteries are on CPU board of the AML main unit.

Replace both 2 pieces when you replace the battery.

The built-in clock battery longevity is usually about 10 years.

If the built-in clock batteries are worn out, replace them according to the following procedures.

4. Install the CPU board in the AML main unit.

1. Remove the CPU board from the AML main unit.

5. Reconnect the connector to the board.

2. Remove the battery from the battery holder on CPU board by pressing the battery diagonally.

[NOTICE] When removing the battery, remove while holding the battery upper (positive side) because the battery may pop up.
