TM 5-6675-348-13&P
Reference. Allows a reference elevation (benchmark or sea-level elevation) to be entered into the
a.
elevation display window. The reference elevation does not change the elevation of the blade; only the
numeric value in the display window is changed.
Customize. Allows the Operator to customize certain system functions and features. Functions are
b.
OFFSETS, BEEPER ALERTS, and SLOPE DISPLAY. These functions can be turned on or off, or can
be changed through the Customize program.
Remote Switch. Three functions are available in OFFSET program: Slope Offset, Elevation Offset,
c.
and Auto Raise/Lower. Only one OFFSET function can be selected at any given time. Selected
OFFSET function is activated by using Remote switch.
Slope Offset allows Remote switch to function in adjusting desired cross-slope in increments of
(1)
0.1% to 19.9%. When Remote switch is toggled forward, programmed offset value is added to
displayed cross-slope value. Slope of blade is increased by same value. When Remote switch is
toggled toward Operator, programmed offset value is subtracted from displayed cross-slope value
and slope of blade is decreased by same value. Slope offset allows cross-slope to be transitioned
through zero.
Elevation Offset allows Remote switch to function in adjusting Tracer Sonic Grade Controller or
(2)
EMZE-24 Electric Mast elevation from 0.01 to 3.98 ft (0.003 to 1.213 m). When Remote switch is
toggled toward Operator, programmed offset value is added to displayed elevation value. The
blade's elevation is raised by same value. When Remote switch is toggled forward, programmed
offset value is subtracted from displayed elevation value and blade's elevation is lowered by same
value.
Auto Raise/Lower allows Remote switch to automatically raise blade to a selectable relative
(3)
distance above grade and switches system into inactive automatic operation. Toggling Remote
switch in opposite direction automatically lowers blade to a selectable distance and switches
system into automatic control. If system does not reach desired elevation range, it will remain in
inactive auto mode and blade will have to be manually lowered and switched to automatic
operation.
Beeper. Beeper is used to alert the Operator that certain events are occurring. These functions can be
d.
turned on or off depending on Operator's preference.
Beeper On/Off. With the beeper ON, a single beep is emitted when:
Remote switch is toggled.
A serial communication error is detected.
A sensor error is detected.
An out-of-range error occurs (See Section V, Blade Pro Motor Grader Control System
Troubleshooting Error Messages).
(1)
Beeper I (Elevation).
(a)
Two short beeps are emitted when elevation device is in a fine correction for more than
2 seconds or if a medium or coarse valve correction signal is sent. This alerts the Operator
that the cut is not to grade. A second pass or ripping the material may be required.
Three short beeps are emitted if Tracer Sonic Grade Controller or Laser Receiver loses its
(b)
reference. For example, if a string line is used as a grade reference and Tracer Sonic Grade
Controller is moved off string line, then three short beeps are emitted to alert Operator.
