LEVELWIND
This screen allows the operator to calibrate the
levelwind for advanced level sensor calibration.
To do this simply position the levelwind to the
far right or left using the top joystick lateral
rocker switch then press the corresponding left
or right [CALIB LEV WIND] button to lock in the
sensor position.
On this screen is an additional levelwind float
arm control button. This is in addition to the
[Float Arm On/Off] button located on the HOME
screen. See the FLOAT
ARM ON/OFF Section
for more information.
Within this screen are also options to raise and
lower the levelwind arm. Push and hold the
desired button to initiate corresponding vertical
movement. When the button is released, the
levelwind movement will stop.
DRUM
This button, when pushed, displays the Drum
Setup Screen. This screen allows the operator to
change between the Standard provided
Rope/Cable
Drum and the optional
Reconductoring Drum. To do this simply push
and hold the [SET DRUM] button. This will
toggle
the
configuration
settings
for
the machine
between the
two available
drum sizes. As the
drums are changed the current configuration
will be displayed on the screen along with a
status indicator bar.
CAUTION: If using the levelwind during pulling
operations, the Float Arm function should be set to
[ON]. Failure to enable the float arm function could
result in damage to the levelwind as upward line
tension forces might exceed the downward holding
strength of the levelwind and its retainers.
CAUTION: If the levelwind arm is in the upward standby
position and the Float Arm function is enabled, the
levelwind arm will drop rapidly, creating a hazard for
personnel and possible damage to the rope or
levelwind. Use extreme caution if personnel are in the
vicinity as the weight of the falling levelwind could
cause significant injury or death if it strikes a person.
NOTE: When either [RAISE ARM] or [LOWER ARM]
buttons are pressed to actuate the vertical movement
of the levelwind, the [FLOAT ARM] function will
automatically change to the [OFF] position. The
operator will have to re-enable the float arm if it is
needed during pulling operations.
