Scale Dimensions:

• Scale available travel length: 50mm-1000mm
• Scale mounting instance: Travel +124mm
• Scale actual length: Travel +142mm
• Scale cable length: 3 meters

2.3 Electrical Connections (DB-9 TTL Signals)

Connect the linear scales to the DRO display unit using the provided cables. The SNS-2V system utilizes TTL signals via a DB-9 connector. Refer to the pinout diagram below for correct wiring.

After connecting the scales, plug the DRO display unit into a suitable power source (AC80-250V 50/60HZ).

3. Operating Instructions

The SNS-2V DRO unit provides intuitive controls for various measurement functions. Familiarize yourself with the display and button layout.

3.1 Basic Operations

• Power On/Off: Press the power button to turn the unit on or off.
• Zeroing: To set the current position as zero for an axis, press the 'ZERO' button for that specific axis.
• Absolute/Incremental Modes: Switch between absolute (ABS) and incremental (INC) measurement modes as required for your machining task.
• Unit Conversion: Use the 'MM/INCH' button to toggle between metric (millimeters) and imperial (inches) units.
• Half Function: The '1/2' button allows for quick calculation of the center point, useful for workpiece setup.

3.2 Advanced Functions

The SNS-2V DRO is full-featured and supports fast programming. Consult the detailed programming guide (if provided separately) for advanced functions such as:

• Hole pattern calculations (PCD, linear array)
• Arc machining
• Tool compensation
• Taper measurement

4. Maintenance

Regular maintenance ensures the longevity and accuracy of your DRO system.

• Cleaning: Keep the display unit and linear scales clean. Use a soft, dry cloth to wipe surfaces. Avoid abrasive cleaners or solvents that could damage the display or scale surfaces.
• Scale Protection: Ensure the linear scales are protected from chips, coolant, and dust. Regularly check the integrity of any protective covers or seals.
• Cable Inspection: Periodically inspect all cables for signs of wear, cuts, or damage. Replace damaged cables immediately to prevent electrical issues or signal loss.
• Environmental Conditions: Operate the DRO system within its specified environmental conditions (temperature, humidity) to prevent malfunction.

5. Troubleshooting

If you encounter issues with your SNS-2V DRO kit, refer to the following common problems and solutions.

• Display Not Powering On:
  • Check the power cable connection to the DRO unit and the wall outlet.
  • Verify the power source is active and within the specified voltage range (AC80-250V).
• No Reading or Erratic Readings on an Axis:
  • Ensure the linear scale cable for that axis is securely connected to both the scale and the DRO unit.
  • Inspect the linear scale and reading head for any obstructions, damage, or excessive dirt. Clean if necessary.
  • Check the alignment of the linear scale and reading head. Misalignment can cause reading errors.
• Inaccurate Measurements:
  • Verify the resolution setting on the DRO matches the resolution of your linear scales (1/5um or 0.001mm/0.005mm).
  • Ensure the linear scales are rigidly mounted and not flexing during machine movement.
  • Perform a calibration check using a known standard.

If problems persist after attempting these solutions, contact customer support.
