Set On-Grade Match
This function allows a current laser strike location to become
the on-grade location. This function is useful when benching
the machine, or to make minor changes to the graded elevation,
in order to reduce operator trips out of the cab. To activate this
function:
1. Position the receiver to the desired elevation while receiving a laser strike.
2. With the Set On-Grade Match Mode LED (item 3) illuminated, press the
SET button to set the receiver and RD20 elevation displays to On-Grade at
the current valid receiver beam strike location. NOTE: If the command is
accepted, the receiver and RD20 green on-grade LEDs will illuminate, the
RD20 will emit a short beep, and the RD20 On-Grade Match LED will
transition to a continuous double-blink indication to show an offset is being
used. If the command is not accepted an off-tone long beep is emitted and no
changes or indications are shown.
NOTE: The vertical range over which a receiver will accept this function
depends on the model and selected deadband. The acceptance limit on
proportional receivers is about 2.5 cm (1 in.) from the edge of the photocell
array so that both above and below grade information can be displayed.
NOTE: The match function does not operate when the LR60W is in the angle
compensation (ACE) mode.
Set Excavating Mode
This function sets up the LR50W or LR60W for optimal
excavator operation, by doing two things: setting the receiver to
offset on-grade, and turning the receiver plumb indication on.
Offset on-grade is a fixed position on the receiver indicated by a
symbol on the back of the receiver, and is used to provide
excavator operators more notice they are approaching finished
elevation (so they don’t over dig). Plumb indication on the receiver tells the
operator how plumb the excavator boom is by flashing the elevation LEDs
(slow blink = boom retracted, fast blink = boom extended, solid LEDs = boom
is plumb).
To activate this function:
1. With the Excavating Mode LED (item 4) illuminated, press the SET button
to set the LR receiver to optimal excavating mode. The RD20 will emit a
short beep, and the RD20 Excavator Mode LED will transition to a
continuous double-blink indication to show that excavator mode has been set.
NOTE: This function does not operate when the LR60W is in the angle
compensation (ACE) mode.
2. To return the receiver to center on-grade position, press the MODE button
to illuminate the Set Excavator Mode LED, then press the SET button. A
short beep will be emitted, the Excavator Mode LED double-blink indication
will stop, and receiver on-grade position returns to the center location.
NOTE: When in Excavator Mode, the On-Grade Match function valid range
is limited to the center of the photocells up to 2.5cm (1 in.) from the top of
the photocells.
Match Receiver Blade-Tilt
This function sets the current tilt position of the LR50W or
LR60W to indicate center (green LED) on the RD20. This
function is used to match an existing tilt for drainage or for
grading conical shapes, such as baseball infields or water tank
drains. To activate this function:
LR60W: Blade-tilt display must be enabled at the receiver for the RD20 to
display or match tilt. To toggle blade-tilt display on/off at the LR60W, make
sure the receiver is turned on, then momentarily and simultaneously press the
Power, Plumb and Deadband buttons at the same time. This toggles blade-tilt
display at the RD20 on or off. Tilt accuracy on the LR60W is fixed at the fine
(+/- 0.5º) setting.
LR50W: Blade-tilt display must be enabled at the receiver for the RD20 to
display or match tilt. To toggle tilt display on/off at the LR50W, make sure
the receiver is turned on, then press and release the blade-tilt button on the
receiver to toggle tilt display at the RD20 on or off. Tilt accuracy is also set at
the receiver and has 3 settings: fine (+/- 0.5º), standard (+/- 1.5º) and wide
(+/- 2.5º). To cycle through and select one of these options, press and hold the
receiver power button; then simultaneously press the blade-tilt button. The
current accuracy selection flashes rapidly. To change the current selection,
continue pressing this button combination while the status LED is flashing.
1. With the Match Receiver Tilt Mode LED (item 6) illuminated, press the
SET button to set the current receiver tilt to the center, green LED on the tilt
display. The RD20 will emit a short beep, and the RD20 Blade-tilt Display
will change to the center green LED. The RD20 retains the last set blade-tilt
angle after a power cycle.

Setting Functions: MODE and SET Buttons
To select the below functions, press the MODE button (item 15) repeatedly to
cycle through the functions
While the function that you want to use is illuminated (4 second duration),
press the SET button (item 16) to activate the function. The last selected
function always illuminates first when the MODE button is first pressed.
Functions with multiple settings (such as SET DEADBAND) utilize multiple
SET button presses to cycle through all the settings.
Set Deadband
With the Deadband Mode LED (item 2) illuminated press the SET
button repeatedly to cycle through the available deadbands. The
selected deadband will be displayed on the LR receiver and also on
the main RD20 elevation display (item 14), with FINE indicated by
the 2 on-grade LEDs, and wider deadbands (up to 4 total depending
on the receiver) indicated by additional LEDs above and below
on-grade. The receiver and RD20 retain the last deadband setting after a
power cycle.
NOTE: The available deadbands are limited to fine and standard sensitivities
only when the LR60W is in the angle compensation (ACE) mode.
NOTE: If the LR60W and LR50W are in excavator mode the On-Grade
Match function valid range is limited to the center of the photocells up to
2.5cm (1 in.) from the top of the photocells.
3. To return to the center on-grade location, press the MODE button to
illuminate the Set On-Grade Match LED, then press and hold the SET button
for 4 seconds. A short beep will be emitted, the On-Grade Match LED
double-blink indication will stop, and on-grade position returns to the default
location. Another way to return to the center on-grade location is to cycle
power on the RD20.
