Troubleshooting Guide L-700

Problem Possible Solutions
1. No Laser Beam
  • Check laser is turned on and check switch. When the laser beam is switched on, the red LED on the faceplate lights up to safely indicate that the unit is on.(figure 1) Also if the LED on front of laser is on but dim, it’s probably a low battery. If LED is bright, then the laser diode has probably failed and unit should be sent in for repair.
  • Make sure laser shutter is open. Use a straight-edge screwdriver to open or close the shutter. (figure 2)
  • Replace battery (new? Inserted correctly?) (See Appendix A)
  • Check for switch damage.

2. Beam Is Not Round
(use white paper to see beam)
  • Clean laser optics with alcohol
  • Make sure optics are not scratched to cracked
3. Beam has satellites
(use white paper to see beam)
  • Clean laser optics with alcohol
  • Make sure optics are not scratched to cracked
4. “—“ shown in Software Target Display
  • This means Software does not see the computer interface.
  • Check target connections
  • Check cable connections
  • Target has to be connected to R-358
  • Make sure R-358 has been charged up (Note: the R-358 takes 3-5 minutes to show a connection to Software when battery is fully discharged
  • Check connectors for broken pins or wires in connectors
  • Make sure in TARGET SETUP that ACTUAL TARGETS is chosen under DATA SOURCE tab. (See Figure 4)
  • Check for kinks in the cables
  • NOTE: Extremely bright light shining on the face of the target can also cause the display to blank out
5. If green LED on R-358 is illuminated, but there are “—-“ in the display
  • Probably means Software has been set to the wrong interface
    – i.e. the R-358 has been set to Hi Res but Software has R-355 Lo Res mode selected. (See Figure Below)

6. “OFF TGT” Shown in Target Display
  • This means Software sees the R-358 but not the target
  • Check target connection
  • Target has to be connected to R-358
  • Check connectors for broken pins or wires in connectors
  • Check for kinks in the cables
  • Make sure laser is turned on (See figure 1)
  • Make sure laser beam is bright (use white paper to see beam)
  • Make sure the beam is hitting the center of the target window
  • -Check to see if target angle is too severe – Note the angular range of the T-261A is somewhat limited, so the angle of the target has to be within =/- 0.5 degrees.
7. Numbers in Target Display Jump Wildly
  • Make sure in TARGET SETUP that ACTUAL TARGETS (not RANDOM DATA) is chosen under the DATA SOURCE tab. (See Figure Below)

8. Numbers in Target Display are noisy
(jump up/down by more than 0.002 mm in 2 meters)
  • Check for vibrations (try turning off machine)
  • Check for warm or cold air (relative to ambient temp)
    blowing between laser and targets
  • Some A/C power charges for laptops are noisy and can cause noise in the measurements. Try unplugging computer.
  • Check laser and target mounting setups to ensure tight clamp.
  • Increase data averaging in Software
9. Software Crashes upon Loading
  • Make sure USB/Serial Converter cable is connected to the laptop
10. No Negative (or Positive) readings are displayed
  • Check for broken wires or pins pushed out of Target connectors. Target will probably need repairing
  • Make sure the screws on Target Connector are tightened in the R-358
11. Get very odd results
  • Possible corrupt Targets.ini file (in Windows folder) or Hamar.ini (in Software32 folder). Rename both files. WARNING this will delete all target setup and calibration factors
  • Make sure the screws on Target Connector are tightened in the R-358
12. R-1307 Readout not visible to Radio Devices The following is applicable to the R-1307 only:

To make the unit visible to all other radio-enabled devices, you must set the Target Network ID and the System ID for the readout.

  • Set the Local Target Network ID
    Press the MENU button until the upper display shows
    with the current Target ID () blinking. Use the
    UP and DOWN arrow keys to set the Target ID (the default is 01).Press the MENU button again until the lower display shows  with the current Target ID () blinking. Use the UP and DOWN arrow keys to set the Target ID to the same value as that of the upper display’s Target ID (the default is 01).
    The upper display will show the vertical (Y) axis position of the local target.
    The lower display will show the Horizontal (X) axis position of the local target.
  • Set the System ID (Radio Channel)
    Press the MENU button until the upper display shows , with the current System ID ( ) blinking. Use the UP and DOWN arrow keys to set the System ID (the default is 01).

APPENDIX A – Replacing Batteries in the L-700

Replacing the Batteries
The battery pack uses two 9-volt batteries. The batteries are housed in a two-part case which is held together by flathead screws. Hamar Laser recommends using alkaline or nickel-cadmium (NiCad) cells for best performance.

  1. Unplug the battery pack from the laser.
    Pull the probe out of the laser control panel and gently set aside.
  1. Unscrew the cover of the pack.
    Locate and loosen the two captive flathead screws, and remove the cover.
  1. Replace the two batteries.
    Remove the old batteries and replace them with new 9-volt cells, being careful to orient them with the negative terminal out (or up).
  1. Re-attach the cover.
    Put the cover back on and secure it to the battery pack with the screws.

Requirements for Radio Devices

As used in this manual, a system is a collection of radio devices that have been assigned a set of common frequencies, grouped into a channel. The terms channel and System ID are functionally interchangeable.

All radio devices, for example the A-1519 and the R-1307W, need to be configured for the same radio channel in order to communicate with each other. Set all devices that are part of a system to the same channel:

  • Readout: ‘setting
  • Wireless Target(s): System ID switch setting.

Within radio range, or for all practical purposes within the same facility, there can only be one Master Device in ‘mode per system. This applies to any Hamar Laser radio devices, including the R-1307 and R-1307W and the A-910 Radio Transceiver.

There can only be one target with the same Target Network ID per system.

Frequently Asked Questions

Q I need to read three targets simultaneously, requiring a second Master Readout. How can I read more than two targets within the same facility if there can only be one Master Device in  mode per System?

A The second Master Readout and the third target must be configured to operate on another Radio Channel or System ID. For every two targets, you will need an additional Master Readout configured to a different radio channel (see chart below).

 

Q My position readings are noisy. What can I do to steady them?

A First, determine why the readings are noisy. In most cases, reading noise is caused by vibration, air turbulence, or drift in the laser or target mounting structures. If possible, take steps to minimize external influences that cause reading instability. Experiment with the Dampening setting (Menu function ). Increase the number of samples to decrease reading fluctuations (note that higher number of samples results in slower response because reading takes longer to update after a change in position).

Set the display resolution to suit you requirements (Menu function . Don’t set the display to .0001″ resolution when you are working to tolerances of .001″ or more. The extra digit will only add confusion if conditions are noisy.

Appendix A – Replacing the Battery in the L-700 Laser

The L-700 Lasers use a standard, replaceable 9-volt battery for up to 8 hours of continuous use. For best results, use alkaline or rechargeable Nickel-Cadmium (NiCad) batteries.

To install or replace the battery.

  1. Remove the battery cover.
    Using the 3/32” hex key included with the laser, loosen the two hex screws on either side of the bubble level. The screws do not need to be removed.
  1. Slide the cover out.
    Pull the cover straight out of the laser to access the battery.
  1. Replace the battery.
    Remove the battery (rock it gently from side to side to disconnect it) and replace it with a new 9-Volt battery. Make sure the battery is seated in the clips. If the battery won’t snap in, check to see if the clips are bent or distorted.
  1. Slide the cover on and tighten the screws.
