  • Page 4: Safety Information

    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 prod- ucts 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 disassem- ble 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. It is quite possible for the beam to enter into one's eyes, and it is possible to lose visual sight temporarily, and lose one's caution and awareness of other dangers - avoid glaring beam.

  • 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.

    Additional Magnetic Scanning Targets may be included in some markets. Remote Control Option There are two RL-VH3C models, standard and remote control compatible. Standard models cannot be operated using the optional RC-30 remote controller (see page 36). Remote control compatible models are designated by the letter "R" following the model name on the serial number tag as shown below.

    Horizontal Rotation Set the instrument on any smooth surface that is within ±5° of true level. The RL-VH3C auto-level system will not function if the unit is placed more that 5° out of level. For best operation, it is recom- mended that it be mounted to a tripod or the Top- con Wall Mount Model 1C (provided).

    Vertical Rotation Place the instrument on its back as shown in the illustra- tion. Turn the leveling screw on the instrument until the bubble is centered in the circular level vial. Battery Warning Lamp Flashing : The power is low ON Solid: Dead batteries Replace the batteries with new ones.

  • Page 15: 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 Control Pad.

  • Page 16: Laser Sensor Mode

    For long range or outdoor applications, the instrument can be used with an optional elec- tronic laser sensor. The Topcon models LS-70B or LS-70A are recommended. Press the Mode Control Pad to select Laser Sensor Mode. The beam rotates at 300 rpm in this setting.

  • Page 17: Height Alert Function

    Height Alert function When auto-leveling is active, this function prevents the instrument from operating if it is dis- turbed. This serves as a reminder to the user that to insure accurate control, the height of the beam should be re-checked after the unit has been disturbed. To activate the Height Alert function, depress and Leveling LED hold the left Alignment control pad (see page 10) on...

  • Page 18: 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).Using the Slope Control pads (see page 10), Inclination of the instrument the beam can be electronically raised or lowered 5 degrees above or below the inclination of the instru- ment.

  • Page 19: How To Set Slopes

    How to set slopes Turn the instrument on by pressing the Power control pad. Auto-leveling will start. Press the X/Y Axis Selection control pad once after auto-leveling is complete (see page 10). The X axis lamp will flash. To change to Y axis, press the X/Y pad once again. Press- ing the X/Y pad toggles between X and Y axis selection.

  • Page 20: Line Control

    Line Control (manual vertical beam alignment) Position the instrument for vertical operation as instructed on page 12. Press the Power Control pad to turn unit on. When auto-leveling is complete, the laser beam will be emitted. Select the Laser Pointing operating mode and using the laser beam, position the unit so the beam aperture is directly over point A and is roughly in line with point B (see illustration).

    Maintaining Power Sources How to replace dry batteries Remove the battery cover by turning the battery com- partment lock to “OPEN”. Remove the old batteries and replace with four (4) new “D” cell alkaline batteries making sure each is placed in the proper direction as indicated. Replace the battery cover and turn the knob to “Lock”.

  • Page 22: 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, 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 23: Horizontal Calibration

    Horizontal Calibration (1)Checking Calibration Instrument as seen from above 30m (98feet) Target Wall Panel side Set up a tripod 30m(98ft) from a wall. Mount the instru- ment on the tripod, facing the X1 toward the wall. Turn the unit on and allow auto-leveling to complete. Place a piece of paper on the wall.
  • Page 24 Turn the unit on again and allow auto-leveling to complete. If less than 6mm(.23 inches) No calibration Necessary Make a new mark (Mb) where the laser beam strikes the paper. X1 laser beam Measure the distance between the first mark (Ma) and the second mark (Mb).
  • Page 25 • If the calibration is greater than the adjustment allows, the error LED will start flashing. If this occurs, contact your Topcon dealer. For Y axis calibration, turn the unit as instructed in step 1 above then press the X/Y Axis Selection pad.

  • Page 26: 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 3mm (1/8 of an inch), no error exists. Note • If the error is grater than 3mm (1/8 of an inch), contact your Topcon dealer.

  • Page 27: Vertical Calibration

    Vertical Calibration Perform the following check after completing "Horizontal Calibration" on the previous page. (1)Checking about 20 m about 20 m (66ft) (66ft) Set up the instrument half way between 2 walls a minimum of 40m away from each Wall Wall other.
  • Page 28 . 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 top of the rotary head strikes wall B (Hb). Measure the distance (dHb) between marks Mb and Hb.
  • Page 29 When the flashing stops, the vertical calibration adjustment is made and power is turned off. Note • If the calibration is greater than the adjustment allows, the error LED will start flashing. If this occurs, contact your Topcon dealer. Repeat the checking procedure to confirm proper calibration has been made.

  • Page 30: Storage Precautions

    Storage Precautions Always clean the instrument after use. Use a clean cloth, moistened with a neutral detergent or water. Never use an abrasive cleaner, ether, thinner benzene, or other solvents. Always make sure instrument is completely dry before storing. Dry any moisture with a soft, clean cloth.
