We recommend that you become familiar with the meaning of these Warnings and Cautions before continuing.

  • Page 5: Safety Precautions

    • There is a risk of fire, electric shock or physical harm if you attempt to disassem- ble or repair the instrument yourself. Repairs are to be carried out by TOPCON or an authorized dealer ONLY! • Laser beams can be dangerous and can cause eye injury if used incorrectly.
  • Page 6 CAUTION Use of controls, adjustment to the laser, or the performing of any procedures other than those specified herein may result in hazardous radiation exposure. DO NOT allow anyone to work directly in the path of the laser beam. Always make sure the laser is operating above the height of your crews heads. Exposure to laser light may cause momentary blindness.

  • Page 7: User Precautions

    User Precautions Always wear protective clothing (safety shoes, helmet, etc.) when operating. Exceptions from Responsibility The user of this product is expected to follow all operating instructions and make periodic checks of the product’s performance.

  • Page 13: Basic Operation

    Basic Operation Set the RL-H2Sa on a tripod or flat surface. (See "Instrument Set-up Procedure " on page 12.) Turn the instrument ON and enter a grade if desired. (See "Entering Grade " on page 18.) Set beam rotation to the desired speed.

  • Page 14: Preparation And Functions

    For battery installation instructions, see "Maintaining Power Sources " on page 22. Instrument Set-up Procedure Set the instrument on any smooth surface that is within ±5° of true level. The RL-H2Sa auto-level system will not function if the unit is placed more that 5° out of level. For best operation, it is recommended that it be mounted to a tripod.

  • Page 15: Battery Warning Indicator

    Battery Warning Indicator The Battery warning indicator indicates the battery power remaining. Battery is sufficient. The power is low, but laser is still usable. In this state, the laser will transmit the battery warning signal to laser sensor. AC/DC converter AD-9B or AD-7C is available for continuing the operation. Dead batteries.

  • Page 16: Auto-Leveling Lamp

    Auto-leveling lamp Flashing : Auto-leveling is in process. When automatic leveling is almost complete, the flashing rate will be slow. The head will not rotate and the laser beam will not emit during the auto-leveling process. ON Solid:Auto-leveling is complete. The rotary head is active and emits the laser beam.

  • Page 17: Inclination Warning

    Inclination Warning If the instrument is inclined out of automatic grading range (usually approximately ±5°, but ±2° according to the set grades). The Auto-leveling lamp will flash and the grades will disappear. Set the instrument as hori- zontally as possible and turn off/on the instrument again. (This warning may be displayed about six minutes or more after powering ON.) Blinking...

  • Page 18: Changing Rotation Speed

    Changing rotation speed Press Rotation Control key to activate rotation speed mode. Select the rota- tion speed 300 r.p.m, 600 r.p.m or 900 r.p.m by pressing the arrow keys. Press the Enter key to accept the setting. Height Alert function When auto-leveling and height alert function are active, this function prevents the instrument from operating if it is disturbed.

  • Page 19: Aligning Direction Of Grade

    Aligning Direction of Grade When using the laser with a percent of grade entered, the laser must be properly aligned so the slope of the laser beam is parallel to the desired direction of grade. The sighting collimator on top of the instrument is cali- brated to the grade axis of the laser beam.

  • Page 20: Entering Grade

    Entering Grade The laser beam can be sloped in either the X or Y axis (single slope) or both axes (com- pound slope). Grade range: Single axis: -8.000 to +8.000%, Dual axes: |X| + |Y| ≤ 10.000% Compound slope Single Axis Dual Axes Plus (+) Minus (-)

  • Page 23: Masking (Laser Beam Shutter)

    Masking (Laser beam shutter) The RL-H2Sa features electronic beam “masking” to prevent the beam from transmitting on one or multiple sides of the instrument. This can be useful to eliminate duplicate laser beams on job sites where more than one laser may be in use.

  • Page 24: Maintaining Power Sources

    Maintaining Power Sources Installing Insert the BT-51Q rechargeable battery into the instrument. Place the DB-51C rechargeable battery holder firmly into the instrument and turn the bat- tery cover knob to “LOCK”. Charging Plug the AC/DC converter (AD-9B or AD-7C) into the charger jack on the DB-51C rechargeable battery holder.
  • Page 25 Automatic protection feature; In case of overcharge or high or low temperature state exceed- ing charging range, charging will be stopped or changed to protect battery.
