LASER ON Status LED States How the LED lights up depends on the average height of the target object within the LED lighting X-axis range. It lights up green when the average height of the target object is within the LED lighting Z-axis range, or orange when the height is outside the LED lighting Z-axis range but within the Z-axis measurement range. When the height is outside any Z-axis measurement range, the light flash orange.

"Sheet-Fed" and "Continuous" Import Images captured with the LJ-X Series can be imported using the two methods below.

Sheet-Fed Import

> Capture one image at a time

Used when inspecting individual parts, etc.

Continuous Import > Continuous image capture Used when inspecting targets such as sheets or cables one after another.

12

Selecting Between Sheet-Fed and Continuous Import Select "Capture Area Settings" from under "Head" in "Head Settings".

Select either "Sheet-Fed" or "Continuous" for "Capture Method".

This completes the setup for sheet-fed/continuous import.

13

1.2 Setting the Optimal Position Checking the Default State and Installing at the Reference Distance Create new inspection settings. This section describes how to carry out initial setup using the controller.

A screen like the one shown below will display when the device is powered on for the first time. Select the mode and language.

A screen like the one shown to the left will display when the device has been restarted. Firstly, use the corresponding function to confirm that the head is installed at the optimal height. Open "Head Settings".

Users can visually confirm how the laser is reflected back from the inspection target. If it is at or near the screen centre as shown in the photo to the left, it has been set up near the reference distance. If it is not at or near the screen centre, or if it is angled, adjust the head installation height and angle. • Reduce head height -> Profile moves upward • Increase head height -> Profile moves downward

*The system can display measurements in inches when using both 2D and 3D modes. Follow the procedure below to switch to inches.

Select System under Global, then select Decimal Point

(1) Click here (2) Next, click here

Notation. Click the points shown to the left in the sequence shown. An item for inch units will display on-screen.  Select Inches and click OK. Restart, and inch display will be available for use.

14

Adjusting Exposure Time and Dynamic Range Next, adjust the exposure time and dynamic range. *Adjust while observing the amount of received light when stationary. This section describes how to check the screen and the amount of received light. This may not be appropriate for actual line adjustments. Be sure to account for this in practice. Open "Head Settings" and enter the "Capture Settings" item.

This will open a screen (see image on left) similar to "Checking Installation Conditions" on the previous page. The current amount of received light can be determined to some degree using the wave patterns on the screen that displays at this point. Excessive amount of received light. Reduce the exposure time. Optimal amount of received light. Amount of received light too low. Increase the exposure time.

Also, press ing in the centre section of the screen to display the received light waveforms at the bottom of the screen. The exposure time must be adjusted to prevent saturation (shown below) of the received light waveform. *Saturated received light waveform (orange section)

15

• Adjusting with "Sensitivity Adjustment" (*Default setting) Click on "Sensitivity Adjustment".

Use the options to select by how much to increase the sensitivity. Insufficient reflected light > Toward "+" Excessive reflected light > Toward "-"

Press ing in the centre section of the screen allows you to handily check the amount of received light while making the adjustments.

16

• Adjusting with "Manual Settings" Add a check to "Manual Settings". This will allow editing of items locked in "Sensitivity Adjustment".

Adjust "Exposure Time". Insufficient reflected light > Increase exposure time For example, 120 µs > 480 µs Excessive reflected light > Reduce exposure time For example, 120 µs > 30 µs

Adjust "Dynamic Range" after adjusting "Exposure Time". Increasing the dynamic range allows for handling of targets with greater variations in reflectance.

Enable the irregular reflection removal filter if there is stray light. *Stray light: A term for unnecessary, scattered light generated in the lens barrels of optical components, etc. (Orange section)

17

• "Irregular Reflection Removal Filter" Add a check to the "Irregular Reflection Removal Filter".

This allows the clear capture of waveforms for sections that were not previously stable. *May have the opposite effect on some targets.

18

1.3 Profile Adjustment Settings Setting up Height Image Filters *Setup for this item is not always required. Carry out setup as needed. Open "Head Settings" and enter the "Profile" item.

Place a check in the check boxes for the filters that will be used. The "Details" button will then become selectable. Press "Details" to adjust the parameters.

The role of each filter is shown below. Refer to the LJ-X8000 Series User's Manual for details on the adjustable parameters.

• Vibration Correction Corrects for vibration factors in height data.

• Dead Zone Noise Removal Cancels out noise data generated from blind spots.

• Noise Spike Removal Removes pixels which protrude out into the periphery, such as noise spikes.

• Invalid Pixel Suppression Uses estimated height data from surrounding valid pixels to interpolate values for invalid pixels for which height data could not be acquired.

2.1 Adjusting Line Scan Intervals Adjust X:Y so that the ratio is 1:1

2.2 Using Programmable Encoders Configure the required settings for using the programmable encoder

20

2.1 Adjusting Line Scan Intervals What are Line Scan Intervals? • Time-specified: Set the import intervals for each line by time (µs/line). • Programmable encoder-specified: Set how many programmable encoder counts are handled as a line (count/line).

If the line scan interval is not adjusted properly, processed images will be displayed with vertical elongation or compression.

Adjusting Line Scan Intervals • When line scan intervals are time-specified Utilise the trigger input and move the targets to project the processed images. If the processed images are vertically elongated or compressed, adjust the scan frequency according to the travel speed of the target. If the processed image ranges are too wide or narrow, adjust the number of import lines. Go into "Head Settings" and change "Line Scan Interval", then check for elongation or compression of processed images.

Increase time > Compresses images Reduce time > Elongates images Change "Number of Lines" under "Capture Area Settings" if adjusting the number of import lines.

21

• When line scan intervals are programmable encoder-specified Utilise the trigger input and move the targets to project the processed images. If the processed images are vertically elongated or compressed, adjust the line scan interval according to the travel speed of the target. If the processed image ranges are too wide or narrow, adjust the number of import lines. Go into "Head Settings" and change "Line Scan Interval", then check for elongation or compression of processed images.

Change "Number of Lines" under "Capture Area Settings" if adjusting the number of import lines.

You can check the count status of the Programmable encoder. Enter the travel range for 1 pulse (×1 Sampling) for the Programmable encoder. *Programmable encoder input is at the same pitch as for single lines, but data identical to the acquired data is generated and interpolated. Increasing line interpolation elongates images. Reducing line interpolation compresses images. For example, 4-line interpolation Blue: Acquired data, Red: Interpolation data

22

2.2 Using Programmable Encoders What are Programmable Encoders? Programmable encoders are sensors that detect the direction of travel, travel range and angle of rotating or moving objects. Furthermore, with the LJ-X8000 Series, using the dedicated encoder (CA-EN100H/U) allows for the number of pulses per revolution to be set to any value, making it easy and flexible to set up in a manner which suits different worksites. Even if not using the dedicated encoder, the number of pulses can still be easily adjusted via "Line Scan Interval Adjustment".

Using the Dedicated Encoder Open "Line Scan Interval Settings" under "Head Settings". Add a check to "Manual Settings", then open the details. Add a check to "Use Dedicated Encoder", then open "Line Scan Interval Adjustment".

To use the dedicated encoder, the LJ-X and dedicated encoder must be connected via an RS-232C cable.

■ Connection Example

Encoder head cable CA-EN5 (5 m: sold separately) Programmable encoder relay unit CA-EN100U

Encoder head CA-EN100H (sold separately)

RS-232C cable*1 (2.5 m: accessory)

Image processing system controller LJ-X8000 (sold separately)

RS-422 cable (2.5 m: accessory)

24 V DC power supply (sold separately) *1. Connect only when setting the number of pulses for the unit.

• Example when using "XY Ratio Adjustment Navigation" Captures images with current encoder parameters, and temporarily sets a scaling coefficient based on actual size values and measurement values (number of pixels) obtained from captured images. Programmable encoder parameters will be calculated automatically to bring the temporary scaling coefficient X/Y values closer to 1:1. Press "XY Ratio Adjustment Navigation".

(1) Press

.

(2)Utilise TRG input, and capture images while a target workpiece with a known width travels in the X and Y directions. (3)Display images by importing images for the number of lines. ◆ How to handle when a "trigger pass" occurs in (3) • Move the target slowly • Enter a value lower than 1 in "Specify Change Scale Factor", and calculate after first performing vertical compression • Reduce the number of pulses per revolution* • Increase the number of import pulses per line *When using a KEYENCE dedicated encoder (4)Utilise TRG input again, and obtain the number of pixels in the vertical or horizontal direction based on the image captured with the current programmable encoder parameters. Next, enter the actual size values to calculate the scaling coefficient.

*Actual sizes are measured in mm units.

The scaling coefficient is calculated. (5)Press the "Reflect Parameters" button, and encoder parameters will be calculated automatically to bring the temporary scaling coefficient X/Y values closer to 1:1.

24

Using Programmable Encoders from Other Companies The basic procedures for when using programmable encoders from other companies are the same as those for the dedicated encoder. *See the previous page for the procedures. What is different is the result displayed when the "Reflect Parameters" button is pressed. • With dedicated encoder

Number of pulses per revolution



Line scan intervals

Sampling • With a programmable encoder from another company

Number of pulses per revolution



Line scan intervals



The above items will be displayed accordingly.

The pulley size or encoder pulses are fixed when using encoders from other companies, and so, the corresponding pulley sizes or numbers of pulses must be calculated in advance. If using the dedicated encoder, the number of pulses per revolution can be adjusted, allowing users to make fine adjustments according to the specifications of the devices being used.
