Depending on the laser system configuration that you purchase, the laser is shipped with either rechargeable nickel-cadmium (Ni-Cd) or nickel/metal-hydride (Ni-MH) batteries.

Temperature affects battery-charging time. For the best results, charge the batteries when the ambient temperature is in the range from 10 °C to 40 °C (50 °F to 104 °F). Charging at a higher temperature may damage the batteries. Charging at a lower temperature may increase the charge time and decrease the charge capacity, resulting in loss of performance and shortened battery-life expectancy.

Even if you buy a laser that uses Ni-Cd batteries, you can upgrade to Ni-MH batteries. The upgrade installation, however, must be performed by an authorized service center.

Alkaline batteries can also be used as a backup; however, rechargeable batteries should be reinstalled in the laser as soon as possible.

To let you know when the batteries are getting low, the status LED flashes. When the status LED flashes yellow, the laser has less than one hour of running time. When the status LED remains on solid yellow, the batteries have less than five minutes running time.

After shipment, the batteries may not have enough power to operate the system. Be sure to recharge the batteries before use. The intelligent recharger maximizes battery life and reduces the time before battery replacement by precisely controlling the recharging/discharging cycle and by not overcharging the batteries. The maximum time to achieve a full charge is six hours.

Learning basic radio remote control functions 30.1

The radio remote control is a hand-held device that allows you to send operational commands to the laser from a remote location. While using the radio remote control, make sure its antenna is pointing skyward. For example, if you’re holding the radio remote control in your hand and using it in the horizontal orientation, the antenna should be at a 90° angle to the radio remote control.

If you connect the radio remote control to a grade rod, and the radio remote control is oriented vertically, the antenna should point upward from the top of the radio remote control.

CHAPTER

Automatic Alignment Modes 5

Summary 5.1

The laser system has three automatic alignment modes:

• Axis Alignment

• Grade Matching

• PlaneLok

To use these modes, a radio remote control and hand-held receiver are required. The radio remote control and receiver are typically mounted to a grade rod, which must be placed somewhere between 20 m (60 ft) and 150 m (500 ft) from the laser. Automatic axis alignment can take from 1 – 5 minutes to complete.

Automatic axis alignment mode 51.1

This automatic axis alignment function replaces the manual alignment scope and vernier base traditionally used to align the desired grade axis to a hub.

When this mode is being used, the receiver and radio remote control are mounted to a grade rod, the desired grade is dialed into the laser, and the grade rod is placed on the hub that the grade axis is being aligned to. When activated, automatic axis alignment mode adjusts the direction the desired grade axis is pointing to by electronically simulating “rotating” the laser on its mounting base. This mode is typically used for agriculture, road construction, and steep-grade applications where precision alignment of the grade axis is required.

GL700 Series Laser Transmitter User Guide 37

5 Automatic Alignment Modes

Grade-matching mode 51.2

This automatic alignment function changes the grade of the desired axis to automatically match an unknown grade.

When this mode is being used, the receiver and radio remote control are mounted to a grade rod, the approximate grade (within 1.5° of the actual grade) is dialed into the laser, and the grade rod is benchmarked to the laser-beam elevation at a point within 1 m (3 ft) of the laser. Without changing the receiver’s elevation on the rod, the grade rod is then placed anywhere a grade reading is needed.

When activated, grade-matching mode automatically adjusts the grade up or down to “search” for the receiver. When the center of the receiver is found, the resultant grade is calculated and dialed into the laser, and displayed on the two-way radio remote control.

When grade matching is complete, the receiver can be removed from the alignment point and the calculated grade will remain in the laser. Both axes of the laser can be grade matched in sequence. Grade-matching mode is used for applications where the existing grade is not known, but will remain relatively unchanged (such as installation of a sidewalk or driveway).

PlaneLok mode 51.3

PlaneLok mode works like grade-matching mode, except the receiver is permanently mounted to the desired elevation so that the laser can use the receiver to continually monitor beam elevation. The laser ignores the internal level vial for that axis, using the absolute elevation from the receiver for level control.

PlaneLok Mode is used for applications where extreme precision of the laser-beam elevation is required, such as runway applications.

38 GL700 Series Laser Transmitter User Guide

Automatic Alignment Modes 5

Using Axis-Alignment and Grade-Reverse Modes

5.2

How axis-alignment mode works 52.1

Axis-alignment mode works by changing grade in the aligned-axis direction and cross-axis directions then monitoring the elevation changes of the laser beam at the receiver via the radio remote control. The desired axis-alignment angle can then be calculated and the internal grade system “rotated” electronically to align the simulated grade axis to the desired point.

Important things to know 52.2

Automatic Axis Alignment:

• Replaces the alignment scope and vernier base traditionally used

• Can be done from any side of any axis of the laser, even if grade is dialed into the opposite axis that’s being aligned

• Automatically adjusts the direction the grade axis is pointing to the receiver/remote location

• Electronically simulates rotating the laser on its base to match the hub

For Proper Operation:

• The desired grades must be entered into the laser

• The receiver must be at the correct alignment point

• The receiver must be between 20 m (60 ft) and 150 m (500 ft) from the laser

For Best Accuracy:

• The laser beam must strike the receiver's photocell. You do not need to adjust the receiver to an on-grade reading.

• Set up the laser to align to the elevation reference the farthest away (such as the centerline of the road)

• If the hubs are equally distant, align to the hub with the smallest amount of grade

Automatic Alignment Modes 5

Using Grade-Matching Mode 5.1

How grade-matching mode works 51.1

Grade-matching mode works by changing grade in the selected axis direction then monitoring the elevation changes of the laser beam at the receiver via the radio remote control. Once the laser “finds” the center of the receiver, the resultant grade is calculated and stored in the laser and two-way remote control.

Important things to know 51.2

Grade-Matching Mode:

• Automatically adjusts the grade of the selected axis to match an unknown grade

• Searches for and finds “on-grade” of the mounted receiver within a 1.5° grade range of the final grade (starting with the beam centered on the receiver isn’t necessary)

• Stores and displays the resultant grade on the remote and laser

For Proper Operation:

• The receiver can be removed after alignment, and the resultant grade remains in the laser

• One or both axes can be grade matched in sequence

• The initial grade must be within 1.5° of the final grade before starting

Automatic Alignment Modes 5

Using PlaneLok Mode 5.1

How PlaneLok mode works 51.1

PlaneLok mode works by changing grade in the selected axis direction then monitoring the elevation changes of the laser beam at the receiver via the radio remote control. Once the laser “finds” the center of the receiver, it continues to monitor its position and makes small corrections to hold the beam on-grade.

Important things to know 51.2

• Loss of receiver signal results in laser “out-of-level” mode (no laser beam and rotation)

• The internal laser level vial for that axis is ignored (the receiver is used for level control)

• The opposite axis levels to its internal level vial and grade

PlaneLok

• Works like grade match mode, except the receiver is permanently mounted at the desired elevation to continually monitor beam elevation

• Is used for applications requiring extreme accuracy, such as in runway applications

For proper operation:

• The initial grade must be within 1.5° of the final grade before starting

7. Go to the grade-control hub on the axis to be aligned and set the grade rod on

the hub. Make sure you do not change the height of the receiver on the grade rod.

8. Select “PlaneLok” from the operational menu using the mode button (Μ).

9. Select the axis (1 or 2) that you are aligning using the up (υ) or down (δ)

buttons.

Automatic Alignment Modes 5

10. Press the enter button (ε) to confirm the selection. “Start” then “Wait” appears

in the LCD.

Note – When the PlaneLok function has been completed, “PlaneLok Complete” and a “Lock” icon (padlock symbol) appear in the radio remote control’s LCD.

Note – Alignment can take 1 to 5 minutes to complete. Note – If the PlaneLok function fails, the remote indicates the cause of failure. See

the ‘Troubleshooting” section of this manual for more information. Note – The receiver should be

permanently mounted at this location and at the desired elevation. Use a bipod (commonly used with prism

Rod/prism pole with receiver/remote attached

poles) to hold the grade rod steady for the entire workday.

Note – The resultant grade on the locked axis is displayed in the remote control’s LCD.

Note – The laser continues to servo to the receiver’s elevation signals. Any loss of signal over an extended period of time (1 minute) causes the laser beam to turn off and rotor to stop. The PlaneLok mode must be reactivated when the laser experiences loss of signal over an extended period.

11. To exit the PlaneLok function, select “PlaneLok” again using the mode button.

Then press the enter button.

Note – As a confirmation, “Exiting” appears in the radio remote control's LCD.

As with any precision instrument, the calibration needs checking on a regular basis (such as the beginning of each job, or if the laser has been handled roughly). If the laser is to be used below freezing, be sure to check calibration under those conditions.

The laser has a calibration error when the laser plane coming out one side of the laser is above true level, and the laser plane coming out the opposite side is below true level. Adjusting the position of the laser plane requires making minor adjustments the leveling mechanism using the up ( control panel.
