1. Safety Information

READ ALL SAFETY INSTRUCTIONS BEFORE OPERATION. Failure to follow safety procedures may result in serious injury or equipment damage.
DANGER: HIGH INTENSITY LIGHT. Do not stare directly into the LED emitter when the module is powered. This can cause immediate and permanent eye damage. Use appropriate shielding during operation.
WARNING: ELECTRICAL HAZARD. The module operates on 24VDC. Always disconnect and lock out power before handling, connecting, or servicing the device to prevent risk of electric shock.
CAUTION: HOT SURFACE. The anodized aluminum housing is a functional heat sink and can reach high temperatures during operation. Allow the module to cool completely before handling to avoid burns.
NOTICE: ESD SENSITIVE. This product contains components sensitive to electrostatic discharge (ESD). Always use proper ESD handling procedures, including grounded wrist straps, when working with the module or its open connectors.
NOTICE: Only use a certified Class 2 / SELV power supply rated for 24VDC. Use of an improper power source will void the warranty and may cause irreparable damage to the equipment.

2. Product Overview

The NexBot Robotics 323-016 Vision Lighting Module is an industrial-grade illumination source designed to provide consistent, high-intensity light for robotic vision systems. This module is engineered to enhance image clarity and accuracy in automated inspection, guidance, and identification tasks. Its robust construction and high-performance optics make it a reliable component for demanding manufacturing environments. Key to its performance is the delivery of 1200 lumens of bright, uniform white light with a controlled beam pattern, minimizing hotspots and shadows that can compromise image quality. The flicker-free output is critical for applications with high-speed motion, ensuring that every image captured is perfectly and evenly illuminated, preventing strobing effects that lead to data errors. This consistency is essential for tasks such as defect detection, barcode reading, and component verification on fast-moving assembly lines. Built for industrial durability, the 323-016 module features a rugged, anodized aluminum housing that provides excellent heat dissipation, contributing to a long operational lifespan of over 50,000 hours. It carries an IP67 rating, certifying it as fully protected against dust ingress and capable of withstanding temporary water immersion. This makes the module suitable for use in washdown environments or facilities with high levels of airborne particulates. Operating on a standard 24VDC power supply, it integrates seamlessly into existing control cabinets. The compact design allows for flexible mounting options, either directly on a robot's end-of-arm tooling or as a stationary light source within a work cell. Integration is further simplified with IO-Link connectivity, allowing for remote intensity control and diagnostics.

3. Getting Started

1. Product Overview

The NexBot Robotics 323-016 is a high-performance LED illuminator designed for machine vision applications. It provides 1200 lumens of consistent white light and communicates via the IO-Link protocol, allowing for dynamic control of intensity and mode, as well as access to advanced diagnostics.

2. IO-Link Integration

This module requires an IO-Link Master to function. Download the IODD (IO Device Description) file from the NexBot Robotics support portal to integrate the device into your PLC or control environment. The IODD file contains all necessary information about the device's parameters, process data, and diagnostics.

3. Understanding Process Data

The primary process data exchanged via IO-Link allows for real-time control of the light's intensity and operating mode. This enables tight synchronization with camera triggers and dynamic adjustments based on the part being inspected. Consult the IODD for the specific data structure.

4. Operation

Setting Light Intensity

The module's brightness can be adjusted digitally using an IO-Link parameter. This provides precise, repeatable control over the illumination level, which is critical for consistent vision system performance. The setting is typically a percentage value from 0 to 100.

Tip: For applications with reflective parts, start with a lower intensity and use diffuse lighting techniques to minimize glare and hot spots in the image.

Using Strobed Mode

For high-speed applications, strobed mode provides a brief, high-intensity pulse of light synchronized with the camera's exposure. This freezes motion, eliminates blur, and can significantly extend the life of the LEDs by reducing their total on-time.

Monitoring Device Health

The 323-016 module constantly monitors its internal temperature and total operating hours. This data can be read via IO-Link to schedule preventative maintenance and to detect abnormal conditions, such as insufficient cooling, before a failure occurs.

Tip: Set alarms in your PLC to trigger a warning if the device temperature exceeds its recommended operating range.

Over-Temperature Protection

To protect itself from damage, the module will automatically reduce light output if its internal temperature surpasses a critical threshold. This event is flagged in the device's diagnostic status bits, alerting the control system to a potential cooling issue in the environment.

Cleaning and Care

The optical performance of the module depends on a clean, unobstructed lens. Periodically inspect the lens for dust, oil, or other contaminants from the industrial environment and clean it according to the maintenance schedule.

Tip: Never use abrasive cloths or harsh solvents on the lens, as this can damage the anti-reflective coating.

5. Maintenance Schedule

IntervalTaskNotes
WeeklyInspect and clean the outer lens. Use a microfiber cloth with a 70% isopropyl alcohol solution to remove any smudges, dust, or residue.A clean lens is the most important factor for consistent light output.
MonthlyCheck the security of mounting bolts and brackets. Tighten if necessary to prevent misalignment due to machine vibration.Changes in alignment will require vision system recalibration.
MonthlyInspect the full length of the power/data cable for signs of chafing, pinching, or chemical exposure. Ensure the M12 connector is still securely fastened.Pay special attention to cable sections within flexible conduits or near moving axes.
QuarterlyClean the anodized aluminum housing to ensure optimal heat dissipation. Use a soft brush or low-pressure compressed air to remove accumulated dust.Ensure the unit is powered off before cleaning the housing.
AnnuallyReview IO-Link diagnostic logs for any recurring faults or over-temperature warnings. A pattern of warnings may indicate a worsening environmental or power supply issue.Use this data to inform your predictive maintenance schedule.

6. Troubleshooting

SymptomPossible CauseSolution
Light module does not power on.No or insufficient power, reverse polarity wiring, or internal fault.Use a multimeter to verify 24VDC (+/- 10%) is present at pins 1 and 3 of the M12 connector. Confirm wiring is correct. If power is correct, test with a different cable.
Light flickers or appears unstable.Unstable power supply, loose M12 connection, or misconfigured strobing.Check the power supply for voltage drops under load. Reseat the M12 connector. Verify trigger settings and pulse widths in the PLC logic.
Cannot establish IO-Link communication.Incorrect IODD file, faulty cable, incorrect port configuration on master, or device fault.Ensure the correct IODD file is installed. Check cable for continuity on Pin 4. Verify the IO-Link master port is enabled and configured for COM3 speed. Cycle power to the module.
Light output is dimmer than expected.Low intensity setting via IO-Link, active over-temperature protection, or LED degradation.Verify the intensity parameter in the controller is set to the desired level. Check the device temperature via diagnostics. If operating hours are extremely high, the module may be nearing its end of life.
Dark spots or uneven illumination in the vision image.Dirty or scratched lens, or incorrect positioning of the light.Clean the lens according to maintenance procedures. Adjust the module's angle and distance from the target to achieve uniform lighting. Check for obstructions between the light and the target.
Module reports an over-temperature fault.High ambient temperature, blocked airflow around the housing, or continuous operation at 100% intensity.Verify the ambient temperature is within the specified operating range. Ensure the housing has adequate clearance for air circulation. If possible, reduce intensity or use strobed mode.
