Selecting Number of Part-lines of Rope
[NOTICE]
If the registered number of part-lines of rope is smaller than the standard number, a maximum allowable lifting load is limited, depending on the registered number. In case the number is registered as ‘0’, however, a process takes place as if the standard number were registered. Similarly, a process takes place on the basis of the standard number of part-lines of rope if the registered number is larger than the standard number.

Selecting Winch Condition
Selecting Jib Mounted Condition
Select the correct winch according to the actual crane condition; otherwise the load moment indicator will show wrong moment ratio, leading you to damage or overturn the crane.
The lifting capacities vary depending on the operating condition. Register the winch selection using the winch selector switch so that the winch selection indicator lamp is as shown in the table below according to the operating condition.
When main winch is employed When auxiliary winch is employed
: Main Winch : Auxiliary Winch
If the jib mounting/dismounting state is set improperly, the load moment indicator can not detect the actual load precisely. The crane operation in this condition could create hazard.
The jib can be dismounted from the crane body when it is not used. The reduced mass of the crane body after jib removal will influence the precision of the load moment indicator. Use this switch to set the jib mounting /dismounting state to the load moment indicator.
[NOTICE]
The key can be inserted in/removed from either “REMOVED” or “EQUIPPED” position.

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.
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 ( GR700EXL-1 )
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 limit height has been stored 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 corresponding lifting height restriction indicator lamp will go off.
Swing Limit
Swing the boom to the desired position, and press a swing restriction key. The corresponding swing restriction indicator will flash and the buzzer will sound continuously, indicating that the swing angle limit has been registered in the memory. When the boom is swing back to an angle within the set limit, the swing restriction lamp stops flashing and stays lit and the buzzer stops. Thereafter, a swing restriction indicator lamp will flash and the buzzer will sound whenever the limit previously registered is reached. (The swinging boom stops automatically.)
To cancel the restriction function, press the corresponding swing restriction key again. The corresponding swing restriction indicator lamp will go out.
[NOTICE]
When registering the swing angle limit, register both the right and left boom swinging restriction positions. Registering only one side cannot fulfill this working range limit function nor make the alarm buzzer sound.
While the swing stop cancel switch is set to OFF, the automatic stop does not work even if the boom is swung to the limit. In this case, the corresponding swing restriction indicator lamp flashes, a message appears and the AML buzzer beeps for three seconds. Take care when swinging the boom.
