Maintenance and Care
Your receiver was shipped in a protective carrying case. If the receiver is transported
from job to job inside its protective case and normal instrument precautions are
followed, the receiver will provide many years of service. When storing the receiver,
be sure to store it in its carrying case.
Do not wipe dust or dirt off the receiver with a dry cloth as scratching could occur,
possibly damaging these surfaces. Use only a good quality glass cleaner with a soft
cloth on all external components. If these surfaces have hardened concrete or other
materials on them, take the system to your Authorized Service Center for cleaning.
If the receiver will not be used for more than 30 days, remove the alkaline batteries
from it. Be sure to dispose of all batteries properly. Refer to your state or local
requirements for the disposal information.
Controls and Displays Battery Safety
Built-in overcharging protection prevents damage to the receiver if it is left on charge
after being fully charged. Charge protection also prevents damage if you accidentally
try to recharge alkaline batteries.
CAUTION: Do not attempt to charge alkaline or other disposable batteries.
Note: The batteries should only be charged when the receiver is between 0 °C to
45 °C (32 °F to 113 °F).
The rechargeable battery electronics include charge status and charge-error indicators
located on the back of the housing.
Using the Receiver
Operation
Power Button
Press the power button. All the LEDs light and then each row lights from top to
bottom. The LCD cycles through its symbols. If the receiver is out of the laser beam,
the center green LED flashes and the LCD lights to confirm power is on. If the
receiver is in a laser beam, a corresponding LED grade display lights.
Plumb Button
This plumb button has three positions: off, standard, and Angle Compensation
for Excavation (ACE) mode. Plumb indication is generally used during excavation
operations.
Press the button once to change between standard plumb mode and
plumb off. The standard plumb mode is preset to a range of ±2.5°.
The LCD does not show a plumb symbol when it is turned off; it
shows the standard plumb indicator when the standard plumb mode
is selected. The grade indication LEDs flash quickly when the mast
and receiver are extended beyond the plumb range and flash slowly when retracted
beyond the range. The display is solid when the mast and receiver are within the
plumb range.
Angle Compensation for Excavation (ACE) Mode
The receiver displays grade information at wide swing angles of
±10° to 30°. To enter this mode, press and hold the plumb button
for approximately 2 seconds. The on-grade location automatically
switches to the center on-grade and the wider plumb angle symbol
appears on the LCD. A single LED or pair of LEDs light. These
LEDs correspond to the setup length that is input using the scale on the front label of
the display area. A setup procedure is required to compensate for the dipper-arm swing
arc. To determine this length and for more installation information, please refer to the
“Installation-General” section of this guide.
Center/Offset On-Grade Button
Center on-grade or “grading mode” is selected when grade information is useful both
above and below on-grade, as with typical grading operations. Offset on-grade or
“excavator mode” is selected when using a backhoe or excavator. The excavator mode
gives more information and a larger display above on-grade.
Press the button to cycle between the two options. The LCD indicates which mode
is selected and the LEDs display the appropriate pattern. The center on-grade has 7
display channels plus 2 out-of-beam indications. The offset on-grade has 8 display
channels plus 2 out-of-beam indications.
Display-Brightness Button
The display-brightness button controls the LED brightness. Options
include Bright and Dim. Use Dim for normal and lower light
conditions and Bright for sunny daytime operation. Dim conserves
battery life by approximately 50%. Press the display-brightness
button to cycle through both options. The selection is indicated on
the LCD. Additionally, if the receiver is out of the laser beam, the
LEDs display a circle with the current setting.
Out-of-Beam Indication
The LED display indicates if the receiver has moved beyond the vertical laser-reception
range. A sequence of LEDs indicates which direction the implement must be moved
to pick up the beam. The out-of-beam indication continues for approximately two
minutes.
Out-of-Beam Indication Disable
The out-of-beam indication can be turned off if desired. Press the two outer buttons
(Plumb and Display Brightness) at the same time to disable. The receiver displays
the out-of-beam LED sequence in reverse order from both top and bottom. When
disabled, the receiver indicates out-of-beam by flashing the center LED. Press the two
outer buttons again to enable the indication. The receiver remembers the out-of-beam
display state at the next power up.
Installation
General
1. Set up the laser in a safe and convenient location. For more information about laser
setup, please refer to the laser’s user guide.
Note: Operating distances depend on the rotating laser power. The receiver can
pick up the beam from all directions (360°), but it requires a clear line of sight to
the laser.
2. If your laser has selectable rotation speeds, select a high rotation speed. The receiver
can process speeds up to 1200 RPM.
3. To mount the receiver on the mast, turn both the top and bottom knobs
counterclockwise until the mounting clamps in back open enough to fit around
the mounting mast. Place the receiver on the mast. Turn the knobs clockwise to
tighten.
Note: The receiver will mount to round tubing that has a 42 mm to 50 mm
(1.66 in. to 2.00 in.) outside diameter or to 38 mm (1-1/2 in.) square tubing.
4. To remove the receiver from the mast, loosen the two clamps.
For excavation, the receiver may be set up in the trench or above ground.
Angle Compensation for Excavation (ACE) Mode
The horizontal grade checking width is wider as the receiver setup length is decreased.
For example, the closer the receiver is mounted to the bucket, the wider the grade
checking range will be.
The most accurate and repeatable method for checking grade is with the bucket
cylinder fully retracted. The mast must be mounted so that it points to the bucket
teeth in this setup.
Checking grade with the bucket leveled or in other positions provides for faster rough
excavation. The receiver indicates level at the bucket pivot pin in these positions.
It is important to take grade readings only when the bucket is in the original setup
position.
The LED display must be in the direction of the operator
and be perpendicular to the direction of the dipper arm
swing.
For all excavation operations, always take a sample reading
with the bucket “on-grade” and check to make sure the
elevation is correct.
