1. Lifting height upper limit switch
Use this switch to set or cancel the upper limit value of lifting
height.
While the lifting height limit is imposed by detecting the boom
tip height, the display panel displays the lifting height when
the hook is hoisted up to the over winding detected state.
[Setting]
Set the boom to the desired lifting height in a condition in
which no upper limit value is set, and press and hold the
switch.
The monitor display changes to the orange color and the
lifting height is set as the upper limit value.
NOTES
•
Be sure to check, before actual work, that the boom automatically stops at the set lifting height.
If the boom does not automatically stop, reset the lifting height in the above steps.
• When the boom is in the prediction alarm zone or upper limit stop state, an alarm sounds
intermittently only if lowering operation or extension operation is performed.
•
The set value is memorized when the starter switch is turned to the "OFF" position.
When the boom is in the prediction zone or upper limit stop state in a condition in which the lifting
height is set, the monitor display illuminates in orange.
[Cancel]
Press and hold the switch in a condition in which the upper limit value is set. The monitor display
changes to the black color and the upper limit value setting is canceled.
2. Boom angle upper limit/lower limit switch
Use this switch to set or cancel the boom angle upper limit
value and lower limit value.
[Setting]
Set the boom to the desired angle in a condition in which no
upper limit value and lower limit value are set, and press the
switch. The green display appears and the upper limit and
lower limit can be selected. Each time the switch is pressed,
the upper limit and lower limit change. After selecting the one
you wish to set, press and hold the switch.
The upper limit value on the monitor display changes to the
orange color and the boom angle is set as the upper limit value
or lower limit value.
