4. Installation Instructions
Proper installation is crucial for the optimal performance of the sensor. Follow these guidelines for mounting and positioning.
4.1 Mounting the Sensor
The sensor can be mounted using M3 screws with the provided support and lock block. Ensure the sensor is securely fastened to prevent movement or vibration during operation.
4.2 Installation Direction
The orientation of the sensor relative to the target object significantly impacts measurement accuracy. Consider the following:
- Relative to the direction of movement: When measuring objects with significant material or color differences, install the sensor in the direction shown in the figure to minimize measurement errors.
- Measuring rotating objects: For rotating objects, install the sensor in the direction shown to suppress the effects of vibration and position deviation.
5. Wiring and Connections
The GRK-Z100N-RS485 sensor uses a 5-core composite cable. Ensure correct wiring according to the diagram below to prevent damage and ensure proper functionality.
5.1 Wire Color Code

6. Operating Instructions
6.1 Display and Indicators
The sensor features a digital display that shows the 'Threshold Value' and 'Current Value'.
- Red Indicator Light: Illuminates when output is active.
- Green Indicator Light: Illuminates when power is supplied.
6.2 Buttons
- SET Button: Used to enter and confirm settings.
- '+/-' Buttons: Used to adjust values or navigate menu options.
6.3 Measurement Principle
The sensor operates on the principle of triangulation. When the position of the target changes, the incoming light position on the CMOS will move. The displacement of the target object is determined by detecting the position of the incoming light.
Important Considerations for Measurement:
- The detection angle needs to be perpendicular to the measured object within 90° ± 15°.
- Transparent objects cannot be detected.
- Liquids cannot be detected.
- The measurement range cannot be calculated from zero.
7. Maintenance
To ensure the longevity and accurate performance of your GRK-Z100N-RS485 sensor, follow these general maintenance guidelines:
- Cleaning: Regularly clean the sensor's optical surfaces with a soft, lint-free cloth. Avoid using abrasive materials or harsh chemical cleaners that could damage the lens or housing.
- Environmental Conditions: Ensure the sensor operates within the specified ambient humidity and temperature ranges to prevent condensation or overheating.
- Cable Inspection: Periodically check the cable for any signs of wear, cuts, or damage. Replace damaged cables immediately to prevent electrical hazards or signal loss.
- Secure Mounting: Verify that the sensor remains securely mounted and that all screws are tightened to prevent vibration-induced errors.
8. Troubleshooting
If you encounter issues with your GRK-Z100N-RS485 sensor, consider the following basic troubleshooting steps:
- No Power/No Green Indicator: Check the power supply connections (Brown to +V, Blue to 0V) and ensure the voltage is within the 12-24V DC range. Verify the power source is active.
- No Output/No Red Indicator: Confirm that the target object is within the measurement range and the sensor is correctly aligned. Check the output wiring (Black wire). Review the threshold settings if applicable.
- Inaccurate Readings: Ensure the sensor is installed according to the recommended directions (Section 4.2). Verify that the target object is not transparent or liquid. Check for any obstructions on the sensor's optical path. Ensure the detection angle is perpendicular to the target.
- Communication Issues (RS485): Verify the RS485 A+ (Gray) and B- (Shielded) connections are correct and that the communication parameters (baud rate, parity, stop bits) match the connected device.
- Sensor Not Responding to Buttons: Ensure the sensor is powered on. If the issue persists, power cycle the device.
