Observe MAST HUNT in window of Graphic Display.
Observe mast extension value when laser has been found. Once on-grade is found, the system
reverts to MAIN MENU.
After LASER REFERENCING has been used, perform all benchmark elevation setting
Exit CUSTOMIZE menu when finished with all selections.
When laser lock has taken place, a number appears in LASER REFERENCING window.
This value is the amount of mast extension in meters. The value is for installers and has
no significance in determining Bucket-ProTM grade calculations.
When laser lock-on has taken place, laser beam indicator appears in upper right corner
of Graphic Display, and shows status of Laser Reference System at any given time dur-
ing operation. It has nothing to do with elevation or finished grade indication.
Check mast movement in upper right corner of display.
During each digging cycle, HYEX boom or dipper stick can momentarily block laser beam.
When blockage occurs, a question mark (?) appears on Graphic Display. If laser beam is
blocked for more than a preset amount of time (default setting is 60 seconds), LASER
REFERENCING screen automatically appears and gives instructions for achieving new
laser lock-on. Please follow these instructions.
Observe symbols as EM2E-24 Electric Mast movement proceeds.
Work can be done with Laser Reference System in 4 ft (1.22 m) extension range of EM2E-24
Electric Mast before having to rereference. Steeper slopes require shorter distance traveled
before reference must be performed again.
(10) Perform all Benchmark Elevation procedures (Para 4-15).
