4. Setup and Installation

Proper installation is crucial for accurate and reliable operation. Follow these steps carefully.

4.1 Mounting the DRO Display Unit

1. Select a suitable location on your machine tool that provides clear visibility and easy access to the controls.
2. Use the provided mounting bracket to secure the DRO display unit. Ensure it is firmly attached and stable.

4.2 Mounting the Linear Scales

Each linear scale corresponds to an axis (X, Y, Z) of your machine. Match the scale length to the travel of each axis.

1. Identify the appropriate scale for each axis (500mm, 700mm, 1000mm).
2. Mount the linear scale body securely to the stationary part of the machine axis using the provided brackets and fasteners. Ensure it is parallel to the axis of motion.
3. Mount the reading head to the moving part of the machine axis. Ensure the reading head is centered over the scale and maintains a consistent, small gap (typically 0.5-1.0mm) from the scale body throughout the entire travel.
4. Verify that the reading head moves smoothly along the scale without binding or excessive friction.

4.3 Electrical Connections

1. Connect the cables from each linear scale's reading head to the corresponding input ports (X, Y, Z) on the back of the SDS2-3VA DRO display unit. Ensure connectors are fully seated.
2. Connect the power cable to the DRO unit and then plug it into a suitable AC power outlet.

5. Operating Instructions

5.1 Power On/Off

• To power on, press the POWER button. The display will illuminate.
• To power off, press and hold the POWER button until the display turns off.

5.2 Basic Functions

• Zeroing an Axis: Move the machine axis to the desired starting point. Press the ZERO button for the corresponding axis (X, Y, or Z) to set the current position to zero.
• MM/INCH Conversion: Press the MM/INCH button to toggle between metric (mm) and imperial (inch) units.
• Absolute/Incremental Mode (ABS/INC): Press the ABS/INC button to switch between absolute (ABS) and incremental (INC) measurement modes.
  • Absolute Mode: Displays the position relative to a fixed datum point.
  • Incremental Mode: Displays the position relative to the last zeroed point.
• 1/2 Function: Press the 1/2 button to find the center point between two measured positions.

5.3 Advanced Functions (Refer to on-screen menus)

The SDS2-3VA DRO unit includes various advanced functions accessible via the function keys (F1-F5) and menu navigation. These may include:

• Hole Pattern Calculation (PCD)
• Line of Holes
• Arc Machining
• Tool Compensation
• Taper Measurement

Detailed instructions for these advanced functions are typically displayed on the DRO screen or can be found in supplementary documentation if provided by the manufacturer.

6. Maintenance

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

• Cleaning: Use a soft, dry cloth to clean the display unit and linear scales. For stubborn dirt on scales, a mild, non-abrasive cleaner can be used sparingly on a cloth, avoiding direct application. Do not use solvents.
• Cable Inspection: Periodically check all cables for signs of wear, cuts, or damage. Replace damaged cables immediately.
• Scale Alignment: Ensure the linear scales and reading heads remain properly aligned and securely fastened. Misalignment can lead to inaccurate readings.
• Environmental Conditions: Operate and store the unit within the specified operating temperature and humidity ranges to prevent damage.
