How to Use the Working Range Limit Function

[NOTICE]

If the working range limit is registered very close to an obstacle, there is a risk of the crane colliding with the obstacle, depending on the operational status and the manner in which the load is handled. When registering a range limit, allow a sufficient clearance to avoid collision.

The working range limit function gives warning only, and does not automatically stop crane motions. When the alarm buzzer sounds, immediately halt the crane motion.

The working range limit function gives warning when the crane reaches the previously registered boom angles (upper and lower), lifting height or load radius.

The function is useful for handling a load in a confined place because it defines the area in which the boom can operate.

[NOTICE]

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.

Boom Angle Limit

Raise or lower the boom to the desired angle, and press the upper or lower boom angle restriction key. The corresponding restriction indicator lamp will flash and the buzzer will sound continuously, indicating that the boom angle limit has been registered in the memory. When the boom is moved back to an angle within the set limit, the restriction indicator lamp stops flashing and stays lit and the buzzer stops.

Thereafter, the upper or lower boom angle restriction indicator lamp flashes and the buzzer sounds continuously whenever the upper or lower limit previously registered is reached.

To cancel the boom angle limit function, press the boom angle restriction key again.

The corresponding boom angle restriction indicator lamp will go off.

Lifting Height Limit

Move the boom to the desired height, and press the lifting height restriction key. The lifting height restriction indicator lamp will flash and the buzzer will sound continuously, indicating that the height limit has been registered in the memory. When the boom is moved back to a height within the set limit, the lifting height restriction indicator lamp stops flashing and stays lit and the buzzer stops. Thereafter, the lifting height restriction indicator lamp flashes and the buzzer sounds continuously whenever the height limit previously registered is reached.

To cancel the height limit function, press the lifting height restriction key again. The lifting height restriction indicator lamp will go off.

Load Radius Limit

Move the boom to the desired load radius, and press the load radius restriction key. The load radius restriction indicator lamp will flash and the buzzer will sound continuously, indicating that the load radius limit has been registered in the memory. When the boom is moved back toward the non-critical side, the load radius restriction indicator lamp stops flashing, and stays lit and the buzzer stops.

The load radius restriction indicator lamp flashes and the buzzer sounds continuously whenever the limit previously registered is reached.

To cancel the load radius limit function, press the load radius restriction key again. The corresponding load radius restriction indicator lamp will go off.

Functions of and How to Use Adjustment Mode

1. Adjustment Initialization [NOTICE]

Adjustment initialization should be performed only when EEPROM is replaced. If the EEPROM removed from the faulty CPU board is reused when the CPU board is replaced, adjustment initialization is not required. By the adjustment initialization, the conversion factors (standard values specified for each specification) stored within the AML program that convert detected voltage input from the detectors into physical volumes is read out from the P-ROM and written onto the EEPROM.

Perform the initialization only once before the first adjustment takes place. If this initialization is done while adjustments are being made, you must restart the adjustment from the very beginning.

For adjustment initialization, you have to execute the following two menus.

[ï Initialize L&A] : Initialize the conversion factors for boom length, angle, and deflection.

[ï Initialize MMT] : Initialize the conversion factors for moment.

1.1 Procedure of Conversion Factors Resetting
