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 colour and the boom angle is set as the upper limit value
or lower limit value.
NOTES
• Before performing a practical operation, be sure to check if the boom automatically stops at the
specified angle. If the boom does not stop, set the boom angle again by repeating the procedure
mentioned above.
• An alarm sounds intermittently when the boom, which is in the upper limit, is in the prediction zone or
upper limit stop state and only if the raising operation is performed, and when the boom, which is in
the lower limit, is in the prediction zone or lower limit stop state and only if the lowering 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 boom angle
upper limit or lower limit is set, the monitor display illuminates in orange.
[Resetting]
Press the switch in a condition in which the upper limit value or lower limit value is set. The orange display
section can be selected in white frame. Each time the switch is pressed, the selection changes. After
selection, press and hold the switch. The monitor display changes to the black colour and the upper limit
value or lower limit value setting is canceled.
