    Safety Information In order to encourage the safe use of products, to prevent damage to properties, and to prevent any danger to the operator and to others, important warnings are placed on the products and inserted in the instruction manuals. We suggest that everyone understand the meaning of the following displays and icons before reading the “Safety Cautions”...

  • Page 5: Safety Cautions

    There is a risk of fire, electric shock or physical harm if you attempt to disassemble or repair the instrument yourself. This is to be carried out by TOPCON or an authorized dealer, only! Laser beam can be dangerous, and can cause eye injury if used incorrectly.
  • Page 6 CAUTION Use of controls or adjustment or performance of procedures other than those specified herein may result in hazardous radiation exposure. Let the laser beam reach the aimed object or the target without anybody else in the laser beam path. When operating in an open area, avoid radiating laser beam at eye level.

  • Page 7: User

    User Wear the required protectors (safety shoes, helmet, etc.) when operating. Exceptions from Responsibility 1) The user of this product is expected to follow all operating instructions and make periodic checks of the product’s performance. 2) The manufacturer, or its representatives, assumes no responsibility for results of a faulty or intentional usage or misuse including any direct, indirect, consequential damage, and loss of profits.

  • Page 8: Laser Safety

    (IEC Publication 60825-1) provided on the safety standards for laser beam. As per the said standard, RL-VH4DR/G2 standard model is classified as “Class 3R (IIIa) Laser Products”. These are simple products to operate and do not require training from a laser safety officer.

  • Page 16: Operation

    Operation Scanning Mode In scan mode, the laser rotates slowly, “searching” for the Magnetic Scanning Target. When the target is properly placed in the beam path, the laser beam will scan rapidly back and forth on the target and “track” the target as it is moved in its path. To change to scanning mode when operating, press the mode switch control key (see page 11).

  • Page 17: Continuous Scan

    Continuous scan (Scan line length can be “Drawn” and held for “Hands-free” operation) Place target in beam path and hold for a moment. The scanning beam will hesitate, then start again. When the target is now removed the beam will continue to scan automatically. To change the length of the scanning line, move the target left or right after the initial scan hesitation and the scanning line length will increase until the target is removed.

  • Page 18: Plumb Beam Mode

    Plumb Beam Mode You can set the instrument using with the plumb beam for centering. To cancel the plumb beam mode, press any other key (except the plumb beam switch and the power switch). Plumb beam for vertical operation This mode can be used with the Remote Controller RC-40.

  • Page 19: Level Sensor Mode

    For long range or outdoor applications, the instrument can be used with an optional electronic level sensor. The Topcon LS-80G model is recommended. Press the mode switch control key to select level sensor mode. The beam rotates at 300 rpm in this setting.

  • Page 20: How To Remove/Install Head Protector

    How to Remove/Install Head Protector When the head protector post blocks the laser beam and interferes with operation, remove the head protector from the instrument. How to Remove Press the lock button to release the lock. Set the angle of the head protector to approximately 45°. Post Lock button Pull the head protector in the direction of the arrow.
  • Page 21 How to Install Insert the head protector pin into the groove of the instrument until you feel it click. Pin, Groove Bring down the head protector until you hear a clicking sound. Check that the head protector is securely locked.

  • Page 22: Height Alert Function

    Height Alert function When auto-leveling and height alert function are active, this function prevents the instrument from operating if it is disturbed (after the laser beam emits for one minute). This helps insures accurate control. If the height or inclination of the instrument changes, the height of instrument should be verified and re-established if necessary.

  • Page 23: Setting Slopes

    Setting Slopes The laser beam can be manually sloped in either the X or Y axis (single slope) or both axes (compound slope). With the inclination of the instrument as the standard, laser beam can be sloped within the range of ±5°...
  • Page 24 How to set slopes Turn the instrument on by pressing the Power control key. Auto-leveling will start. Press the X/Y axis selection key once (see page 11). The X axis lamp will flash. To change to Y axis, press the X/Y key once again. Pressing the X/Y key toggles between X and Y axis selection.
  • Page 25 Line Control (manual vertical beam alignment) Turn the leveling screw and position the bubble of the level vial on the control panel in the center. Press the Power control key to turn unit on. When auto- leveling is complete, the laser beam will be emitted. Press the plumb beam key to select the plumb beam mode.

  • Page 31: Checking And Adjusting

    The Horizontal Calibration and Vertical Calibration can be easily checked and, in most cases, adjustments can be made by the user. Horizontal Rotation Cone can be checked by the user, but if an error is found, adjustments must be made by a Topcon service facility. Attaching the calibration decals Before calibration, attach the calibration decals to the instrument as shown below.

  • Page 32: Horizontal Calibration

    Horizontal Calibration (1) Checking Calibration 30 m (98 feet) Instrument as seen from above Target Wall Panel side Set up a tripod 30 m (98 ft) from a wall. Mount the instrument on the tripod, facing the X1 side toward the wall. Turn the unit on and allow auto-leveling to complete.
  • Page 33 Turn the unit on again and allow auto-leveling to If less than 6 mm (.23 inches) complete. No calibration Necessary Make a new mark (Mb) where the laser beam strikes X1 laser beam the paper. Measure the distance between the first mark (Ma) X2 laser beam and the second mark (Mb).
  • Page 34 (2) Adjusting Calibration If the distance between either set of marks is more than 6 mm (1/4 of an inch) but less than 25 mm (1 inch), turn the unit off by pressing the [START] key once and use the following procedure to calibrate the laser.
  • Page 35 If the calibration is greater than the adjustment allows, the error LED will start flashing. NOTE (See “Error Code” on page 51) If this occurs, contact your Topcon dealer. When the laser beam is difficult to see, it can be adjusted in the Laser sensor mode or the Laser pointing mode.

  • Page 36: Horizontal Rotation Cone Error

    Measure the distance between the first and second marks on each wall. If the difference between each set of marks is less than 3 mm (1/8 of an inch), no error exists. NOTE If the error is grater than 3 mm (1/8 of an inch), contact your Topcon dealer.

  • Page 37: Vertical Calibration

    Vertical Calibration Perform the following check after completing “Horizontal Calibration” on the previous page. (1) Checking about 15 m about 15 m (49 ft) (49 ft) Set up the instrument half way between two Wall Wall walls a minimum of 30 m (98 ft) apart. (The instrument can be facing either direction X or Y.
  • Page 38 Without moving the position of the front foot, pivot the instrument so the rotary head is now facing wall B. Mark where the split beam emitted from the about 30 m (98 ft) top of the rotary head strikes wall B (Hb). Measure the distance (dHb) between marks Mb and Hb.
  • Page 39 (2) Adjusting Calibration Turn the unit off by pressing the [START] key once. Confirm that unit has shut off before beginning the following procedure. (In step 2 and 3, optional RC-40 remote controller is helpful.) Without moving the unit, press the [ENTER] and [START] keys simultaneously. Press either the right or left key on the Alignment Control key to move the laser beam up or down on wall B until the measurement for the distance dHb is the same as the measurement dHa on wall A.
  • Page 40 (The [ENTER] key for the RC-40: The same mark as the [ENTER] key for the instrument.) If the calibration is greater than the adjustment allows, the error LED will start NOTE flashing. If this occurs, contact your Topcon dealer. Repeat the checking procedure to confirm proper calibration has been made.
