Operation
Power: Press the power switch on the touch panel to turn the
unit on. All the LED's will light briefly, then each LED grade
display row will turn on then turn off from top to bottom. Then
each status indicator will turn on and off. The current deadband
status and on grade location will momentarily display. If the
receiver is out of a laser beam, the center green LED will flash to confirm power
is on. If the receiver is in a laser beam, a corresponding LED grade display
will be indicated.
While the unit is on, pressing and holding the power switch and then pressing
the touch panel switches will activate secondary functions which are indicated
by the symbols above the switch.
To turn the power off, press and hold the power key until the LED's are lit, then
release. Settings will be retained the next time the unit is turned on.
Switch Functions
Tilt Indicator: Press the tilt indication switch to turn the display on
or off. The LED status indicators will display a rolling sequence.
When the function is turned on, the LED's will sequence from
the center outward. When turned off, the LED's will sequence
from the outer LED's inward.
When on, the LED's will provide 5 channels of tilt
indication. The center LED will be on when the blade
or dipperstick is within the tilt accuracy setting. The
right side will light when the operator's right side of the
blade or dipperstick is low. The left side will light when
the left side is low.
Initially the blade tilt indication is set to level. It can be
set to match the current blade slope. See installation
notes on Page 15.
Tilt Indicator Accuracy: Accuracy can be set to fine, standard or wide. Press
and hold the power switch and then press the tilt indicator switch to select and
cycle the tilt accuracy function. The current selection will flash rapidly. Pressing
this switch combination while the status LED is flashing will change the current
selection, sequencing from fine to standard to wide to fine, etc.
Operation
Center / Offset On-Grade Location Switch: Center on-grade
is selected for typical grading or cut/fill operations. This mode
indicates an equal amount of grade information above and
below on-grade. Offset on-grade is selected for typical excavation
operations. This excavation mode gives more information and
a larger display area above on-grade. This mode also enables
the plumb indication which shows the operator when the mast
and receiver are perpendicular to the ground (plumb) for more accurate grade
readings. Each selection uses a different array of LED's
Pressing the switch once flashes the LED of the current on-grade location.
Pressing the switch again while the LED is flashing changes the selection.
Fine
± 0.5º
Standard
± 1.5º
Wide
± 2.5º
Plumb Indication: The plumb indication shows when the mast and receiver
are perpendicular to the ground or beyond the selected deadband range. The
grade display LED's will flash quickly when the boom is extended, and will flash
slowly when the boom is retracted beyond this range. The LED grade display
is solid when the boom is within the plumb range setting.
Plumb Indication Accuracy: Accuracy can be set to fine, standard or wide. Press
and hold the power switch and then press the on-grade location switch to select
and cycle the plumb accuracy function. The current selection will flash rapidly.
Pressing this switch combination while the status LED is activated will change
the current selection, sequencing from fine to standard to wide to fine, etc.
