How to Use the Working Range Limit Function
[NOTICE]
If the selected working range limits allow the crane to approach too close to an obstruction, the crane may be contacted or hit, depending on the operational status and the manner in which the load is handled. When selecting limits, allow sufficient clearance.
The working range restricting function makes the boom automatically stop at the previously registered boom angles (upper and lower), lifting height, load radius and swing angle, 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 was last turned off, enter the settings all over again. IW301-0131E70
Boom Angle Limit
Raise or lower the boom to the desired angle, and press the upper or lower boom angle limit restriction key. The corresponding limit restriction indicator lamp will flash and the buzzer will sound continuously, indicating that the limit boom angle has been stored in the memory. When the boom is moved back to an angle within the set limit, the limit restriction indicator lamp stops flashing and stays lit and the buzzer stops.
Thereafter, the upper or lower boom angle limit 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 limit restriction key again. The corresponding boom angle limit restriction indicator lamp will go off.

Functions of and How to Use User Mode (GT-900-1)
Configuration and Functions of the AML System
The AML system is a safety device provided to prevent overloading of the crane which may cause it to overturn or be damaged. The AML system has various kinds of functions, including the following typical functions. Based on the registered work conditions by operator selection and the signals from various sensors, the crane operations are controlled.
(1) Automatic stop function for overloading
The AML calculates and compares the working and rated moment values and displays them as a percentage. 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) Automatic stop function at backward instability
When the outriggers are extended minimum, the backward stability might be insufficient depending on the work condition. For preventing the overturning to backward, if the backward stability is reduced, message and alarm are output and the crane operation toward the cirtical side (boom raising and boom retracting) stops.
(3) Working range limit functions
When any working range limit is registered to the AML, the crane is controlled so that the crane work posture does not exceed this registered working range limit. When the boom reaches the previously registered restriction, buzzer sounds, and the crane operation stops.
(4) Slow stop function
In the following cases, the boom elevation speed or the boom swing speed gradually decreases to stop before the boom reaches the stoppage position.
• When the automatic stop is caused by overloading (Boom lowering will stop.)
• When the elevating cylinder reaches its stroke end (Boom raising/lowering will stop.)
• When the automatic stop is caused by working range limit function (Boom raising/lowering will stop.)
• When the automatic stop is caused by backward stability (Boom raising will stop.)
The situation of automatic stop due to automatic stop function and working range limit function is as listed below, depending on the working condition.
