Functions of and How to Use User Mode (TR-150-4/GR-150-1) How to Use the Working Range Limit Function
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. (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 off.
[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, 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 has been last turned off, enter the settings all over again. Upper boom angle restricted Lower boom angle restricted
