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 restricting function makes the boom automatically stop at the previously registered boom angles (upper and lower), lifting height and 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 boom upper or lower angle restriction key. The corresponding restriction indicator lamp will flash, 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 illuminated.
Thereafter, the upper or lower boom angle restriction indicator lamp flashes and the AML buzzer sounds for 3 seconds whenever the upper or lower limit previously registered is reached. (Boom raising or lowering stops automatically.) To cancel the boom angle limit function, press the boom angle restriction key again. The corresponding boom angle restriction indicator lamp will go out.

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, 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 illuminated. Thereafter, the lifting height restriction indicator lamp flashes and the AML buzzer sounds for 3 seconds whenever the height limit previously registered is reached. (Boom raising and extending stop automatically.)
To cancel the height limit function, press the lifting height restriction key again. The lifting height restriction indicator lamp will go out.
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, indicating that the load radius limit has been registered in the memory. When the boom is moved to a radius within the set limit, the load radius restriction indicator lamp stops flashing and stays illuminated. Thereafter, the load radius restriction indicator lamp flashes and the AML buzzer sounds for 3 seconds whenever the limit previously registered is reached. (Boom extending and lowering stop automatically.)
To cancel the load radius limit function, press the load radius restriction key again. The load radius restriction indicator lamp will go out.

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
1. Select the main menu [ ï Initialize L&A ] in the adjustment mode, and press the register key to select the menu.
2. When [: Reset DEF. FCT ] appears, reset the deflection factor by pressing the register key.
3. When the message [Done] appears, the deflection factor resetting is completed. Press the display alteration key to return to the main menu.
4. Press the register key again to select the main menu [ïInitialize L&A ] in the adjustment mode.
5. When [: Reset DEF. FCT ] appears, press the scroll-down key to display [：Reset zero. span], and then press the register key to reset the zero span factor.
6. When the message [Done] appears, the zero span factor resetting is completed. Press the display alteration key to return to the main menu.
1.2 Procedures of Moment Adjustment Resetting
1. Select the main menu [ï Initialize MMT ] in the adjustment mode, and press the register key to select the menu.
2. When [Reset MMT] appears, reset the moment factor by pressing the register key.
3. When the message [Done] appears, the moment adjustment resetting is completed. Press the display alteration key to return to the main menu.
