CAUTION

WARNING

Use of controls or adjustments or the performance of procedures other than those specified herein may result in hazardous radiation exposure.

The possible health hazard is in exposing the eyes to the laser beam. Damage to the eyes can occur if the operator stares directly into the beam.

Do not look directly at the laser beam.

Follow the safety precautions below to ensure operator safety:

• Operate the LS-3100(W) series only according to the procedures described in this instruction manual.

Otherwise, injury may occur due to exposure to the laser beam.

• Do not disassemble the sensor head.

Laser emission from the LS-3100(W) series is not automatically stopped if the sensor head is disassembled. If you disassemble the sensor head for inspection or repair, you may be exposed to the laser beam. If the LS3100(W) series malfunctions, contact KEYENCE immediately.

• Do not look directly at the laser beam. Looking directly at the laser beam may result in serious eye injury.

• Protective enclosure

We recommend that you install a protective enclosure around the sensor head to prevent any person from getting near the sensor head during operation.

• Protective goggles

We recommend that you wear protective goggles when using the LS3100(W) series.

CHAPTER 1 Preparation for Measurement

1-5 Safety Features Provided with the LS-3100(W) Series

The LS-3100(W) series has the following safety features:

■ Laser ON alarm LED

Both the sensor head and the controller panel have a visible LED that lights when laser is ready to be and is being emitted.

LEDs can be checked to see if they are lit even when you are wearing laser protective glasses.

■ Delay of laser beam emission

To prevent an operator from being exposed to the laser beam, the laser beam is emitted three seconds after the laser ON alarm LED lights.

■ Laser emission remote control input connector

The laser emission control connector is located on the rear panel of the control unit. The laser can be turned on or off by a remote control signal through this connector.

■ Key-operated power switch

The controller power switch can be locked using the attached key. When the LS-3100(W) controller is OFF, the key can be removed.

■ Laser beam shield

The sensor head transmitter comes with a laser beam shield.

Cover is closed. Cover is open.

CHAPTER 1 Preparation for Measurement

1-6. Preparation for Operation

CAUTION

• Do not mount the scanning head to the place where a certain level of electrical noise is applied or transferred. Isolate the scanning head if electrical noise may be occured. Otherwise, laser diode may deteriorate or become damaged.

• Although the LS controller has been thoroughly inspected before shipment, we kindly request that you check it upon purchase for any damage. Contact the nearest KEYENCE distributor if your LS controller is damaged in any way.

• Precision components are incorporated in the scanning head, therefore be sure not to subject it to shocks.

• The scanning head has been precision set before shipment. Always keep the casing closed to maintain the head's setting.

• The LS controller can operate normally at 0 to 45°C (32 to 113°F) [0 to 40°C (32 to 104°F) for LS-3036/3060] with no freezing and 35 to 85%RH without condensation. Operation outside these ranges may result in malfunction.

Do not connect or disconnect any cables while the power is ON. Otherwise, the laser diode may deteriorate and/or may be damaged.

Note

1. Connect the controller to the scanning head and the transmitter and receiver using the supplied cables.

LS-3032, LS-3034, LS-3036

LS-3033, LS-3033 SO, LS-3060

The LS-3101(W) can be used with LS-3032, 3033, 3036 and 3060.

CHAPTER 1 Preparation for Measurement

2. Ground the controller. (Except for models followed with “W”.)

Grounding the controller to the grounding bar

3. Check first that the power switch of the controller is OFF, then connect it to the outlet using the supplied power cable.

Controller (rear view) LS-3100 Series

Grounding the controller through the grounding outlet

CHAPTER 1 Preparation for Measurement

1-7. Connecting 2 Scanning Heads

CAUTION

Do not connect or disconnect any cables while the power is ON. Otherwise, the laser diode may deteriorate and/or may be damaged.

Note the following for connecting 2 scanning heads to the controller:

• These heads have been factory-set for use either as the HEAD1 or HEAD2. Incorrect connection of the scanning heads will, therefore, result in malfunction. To prevent this, first check the serial No. of each scanning head, then check the serial No. of the HEAD1 and HEAD2 on the back of the controller for correct connection. Each of the scanning heads must be connected respectively to the HEAD1 or HEAD2 connector on the back of the controller.

Connect the correct scanning head to the HEAD1 or HEAD2 connector.

Serial No.

Next, follow the steps (1) through (4) on P4. and 5.

CHAPTER 2

TRIAL OPERATION

1. Connect the controller and scanning head(s). Make sure that the optical axis of the transmitter and receiver are aligned before turning the power ON. Aligning the optical axis is not necessary, however, when using the single-body type scanning head or when the transmitter and receiver are secured on the detachable frame.

2. Laser emission starts in approximately 5 seconds.

3. Make sure that the target is correctly positioned in the measurement area. The measured value will be displayed shortly.

4. The LS controller has been adjusted to the following factory-settings:

Ref.

HI ≥ X ≥ LO GO GO (CH1)

X < LO LOW LO1 (CH1)

Note: X represents a measured value.

■ 7-step differentiation

Choose the 7-step differentiation first, then set the tolerance limits using PRM. When "ON" appears on the display, the comparator output is sent through each of the relays and open-collectors (HI3, HI2, HI1, GO, LO1, LO2, or LO3).

Deletes fractions from measured value on the display. DIGIT SUPPRESS is useful when there is a relatively large difference from one measured value to another. The possibly applicable cases are listed below.

• When the number of measurements for averaging is set to a small number

• When the target is vibrating

•When it is not necessary to obtain precise measurements

This prevents errors involved in reading measured values.

• This function can be used for both the main display and subdisplay. It becomes invalid when the subdisplay is used to show measured values in P-P, PEAK, or BOTTOM mode.

• Although fractions are not displayed, the target is measured down to

A SEG (Segment)

Key

Definition of Segment

Note

Targets placed within the measurement area interrupt the passage of the laser beam, thus creating a light-dark pattern. The border between the light and dark regions is referred to an "edge". Also, each dark or light region separated by the edge is called a "segment".

Edge5 (X-1)

Edge6 (X)

The desired pair of edges is to be selected from those shown above, and the distance between these two edges measured.

• The edges are numbered in the order that they are scanned by the laser (from top to bottom).

• The desired pair from among up to 126 edges can be selected.

Description

4 types of segment pairs, DIA, EDGE1, EDGE2, (m,n), can be measured. The description of measurement for each pair is given below.

DIA: This mode is applicable to measurement of targets’ outer diameters. In the above figure, the distance between edge 2 and edge (X-1) is measured. When there is only one target, its outer diameter is measured. When there are two or more targets, the distance between the upper edge of the upper most target to the lower edge of the lower most target is measured.

EDGE1: The width of the uppermost region where the laser is not interrupted by the target is measured. This mode is applicable to measurement of changes in targets’ diameters. In the above figure, the distance between edge 1 and edge 2 is measured.

EDGE2: The width of the lowermost region where the laser is not interrupted by the target is measured. In the above figure, the distance between edge (X-1) and edge X is measured.

(m,n): The distance between two desired edges is measured. When measuring two or more targets, this mode is applicable to measurement of the outer diameter of each target or to measurement of the gap between two targets.

In (m,n) mode, both "m" and "n" represent the edge numbers ranging from 1 to 126. Make sure that the number specified for "n" is greater than that for "m".

Segment Check

This mode is applicable to segment mode (m,n). In this mode, you are to register the number of segments. If the number of segments detected during measurement is not the same as the registered one, error message " - - - - " will appear. When this happens, the measured value is ignored. This prevents incorrect measurements due to dust, drops of oil, or any other particles on the scanning head. The error message will also appear when the target is displaced from the measurement area.

•Non-clear targets are being measured.

D CAL (Calibration)

Key

In this mode, the LS controller can be calibrated to correct possible measurement errors arising from irregularities on the target surface or inclination of the target. Have ready two gauges of known dimension for calibration. The LS controller can be calibrated for each of segment selectors X and Y.

Procedure 1. Press CAL to calibrate segment selector X. "CAL X" will appear on the

subdisplay. At this time, the segment pair (SEG) remains the same. However, the number of measurements for averaging (AVE) and measurement mode (MODE) will be set respectively to "1024, MOVE" and "NORMAL". The LS controller will be reset to the initial parameters when the calibration is over. Also, the hold and auto-zero functions are cancelled, and the offset function is invalid during calibration.

7. Repeat steps 2 to 5 just as you do for calibrating segment selector X.

8. When you finish the calibration, press any of SEG, MODE, AVE, LIMIT, OFS, PRM, FNC, PROG, or DISP to return to the measurement mode.

• To return to the factory calibration, enter "0.0000" on the upper and lower lines of the subdisplay.

• When "CALIB ERROR" appears on the subdisplay, press CAL to display the return to the previous status.

• When you use only one of the segment selectors X and Y, you can calibrate only the selector you use. When you finish the calibration, first check that "CALIB OK" appears on the subdisplay, then press any of the keys mentioned in Step 8 to return to the measurement mode.

• When you measure the diameter of two round bars with only one scanning head, the measurement position differs one from the other. To ensure higher accuracy, it is recommended that the reference gauge be placed at each position and segment selectors X and Y be calibrated separately.

• For even higher accuracy, the closer the dimension of the reference gauge to the target size, the better.

• You cannot enter negative values.

• The value entered on the lower line of the subdisplay must be greater than that on the upper line. If not, "CALIB ERROR" will appear.

Example of Operation You are to measure a diameter of round bars that can vary from 10 mm to

20 mm. Two gauges, each having 10.0100 mm and 20.1000 in diameter are used for calibration.

Analog Voltage Output

Analog voltage signal for CH1 can be obtained through the MON terminals. The LS controller has been factory-set to convert a range from -60 mm to +60 mm into a voltage range from -6 V to +6V. (No voltage signal is provided for CH2. If voltage signal for CH2 is required, consult the KEYENCE distributor.)

Analog voltage range: A range between -6 V and +6 V can be set to match a desired measurement range. Any value between -999.9999 and

9999.9999 can be selected. Note, however, that the difference between the maximum and minimum measurements (those that you specify to correspond respectively to +6 V and -6 V) must fall within a range between 0.024 mm and 240 mm.

Calibration: When the segment selectors are calibrated, the analog voltage signal through these terminals and RS-232C interface is automatically sent based on the calibrated value.

Offset: When the segment selectors are calibrated, the selected offset value is added to the analog voltage signal sent through these terminals and RS-232C interface.

The analog voltage which appears on the main display and that which is output through the MON terminals are always the same.

CHAPTER 4 Functions and Controls

Input Signal

Program (No. 1 to 10) selector input: P1 to P10

• Used to select the desired program from external equipment.

• When pin 2 (3, 4, ••• or 11) is grounded with GND for an instant, program No. 1 (2, 3, ••• or 10) is selected.

• When two or more pins are grounded at the same time, the program with the smallest number will be selected.

Synchronous input: TIM

• When pin 12 (TIM) is grounded with pin 13, the measured value is retained. This value can be retained until pin 12 is disconnected from pin 13. (The measured value is also retained when terminal 3 on the back panel is grounded with terminal 4).

AUTO ZERO input: ZERO SET

• When pin 14 (ZERO SET) is grounded with pin 15 (ZERO SET pulled LOW), the measured value is reset to "0" (mm or inch) for use as a reference. This allows a variation from this reference to be output as a measured value.

• The AUTO ZERO input uses a one-shot circuit that accepts only the first LOW signal and ignores the following ones. This input, therefore, must be reset first to input another AUTO ZERO input signal.

Output Signal

Functions of Terminal Blocks

Analog Voltage Output Terminals

AUTO ZERO RESET Input: ZERO RESET

• When pin 16 (ZERO RESET) is grounded with pin 15 (ZERO RESET pulled LOW), the AUTO ZERO input is cleared, and normal measurement is resumed.

• The AUTO ZERO RESET input uses a one-shot circuit that accepts only the first LOW signal and ignores the following ones. This input, therefore must be reset first before inputting another AUTO ZERO RESET signal.

Comparator outputs: LO3, LO2, LO1, GO, HI1, HI2, HI3, LO, GO, and HI

• Each comparator output is sent through the corresponding open-collector.

• LO 3 to HI3 are used for 7-step differentiation with CH1. LO, GO, and HI are used for 3-step differentiation CH2 at simultaneous 2-point measurement.

• LO1, GO, and HI1 can be used also for 3-step differentiations.

Analog voltage proportional to the measured value is output. ±6 V is equal to ±60 mm (when voltage range of ±6 V is set to ±60 mm measuring range).

* When two or more terminals are grounded at the same time, the program

with the smallest number will be selected.

When terminals 11 and 12 are connected, the laser emission indicator LED on the front panel lights. And, laser is emitted approx. 5 seconds after the connection is made. When terminal 11 is disconnected form terminal 12, the laser emission indicator LED goes out, and the laser emission stops.

The LS controller is delivered with a jumper inserted between terminals 11 and 12.

Relay: SPST-NO contact, 250 VAC, 2 A (resistive load)

• HIGH OUT terminals: HI

Comparator output is sent through these terminals when the measured value is above the upper tolerance limit.

• LOW OUT terminals: LO

Comparator output is sent through these terminals when the measured value is below the lower tolerance limit.

• GO OUT terminals: GO

Comparator output is sent through these terminals when the measured value is within the tolerance range.

MOUNTING SCANNING HEAD

5-1. Alignment of Optical Axis (LS-3060 and LS-3033 only)

The LS-3060 is delivered with the transmitter and receiver (scanning head) mounted to the detachable frame. When using the LS-3060 with the transmitter and receiver removed from the frame on when using the LS-3033, be sure to align them in terms of the optical axis of the laser. (See the figure below.) Misalignment of the optical axis will cause measurement errors. (A special optical axis checker is available with the LS-3060 and LS-3033. Refer to "5-2. Checking Alignment of Optical Axis" on page 66 for the alignment procedures.)

Not applicable to LS-3033 SO (8073).

Use the POSITION CHECK function to check whether the transmitter and receiver (scanning head) are aligned in terms of the optical axis. The procedure is as follows:

1. Use PRM to display "HEAD1" and "POSITION CHECK" on the subdisplay.

EADH1 OS TP IOI N CHECK

2. Attach the optical axis checker to the receiver.

3. When the transmitter and receiver are aligned in terms of the optical axis, "GOOD" will appear. If not, "P-Err" will appear.

4. When 2 scanning heads are used, press PRM again to display "HEAD2" and "POSITION CHECK". (To use 2 scanning heads, the optional PC board for the second scanning head is required.) Then, use the optical axis checker to check whether the transmitter and receiver of the second scanning head are aligned in the same manner as those of the first scanning head.

OS TP IOI N CHECK

When you use the LS-3033SO (8073), note the following:

1. Optical axis alignment — Install the transmitter and receiver so that the both reference base edge are aligned. This also completes the optical alignment. The optical axis checker, which is provided for standard LS3033, cannot be used for LS-3033SO (8073). No optical axis checker is provided for LS-3033SO (8073) for this reason.

2. Transmitter-to-receiver distance — Set this distance to 120 mm.

Initial Setting

Be sure to turn OFF the power of the LS controller, then set these switches.

Since the GP-IB allows up to 15 devices to be interconnected, an address must be assigned to each device. To assign the address, use the DIP switches on the back panel of the LS controller. (See the figure below). The talk only mode or delimiter can also be set using these switches.

CRL

Set this DIP switch to ON to enable "L ". (To enable

both "C " and "L " or only "C ", set this switch to OFF.)

CHAPTER 6 Optional Interface Boards

Setting Address

Setting Talk Only Mode

Setting Delimiter

Use the 1st to 5th DIP switches from the right (4, 5, 6, 7 and 8 in the figure) to set the address. Addresses "0" to "30" can be set. To set the address to "11", set the DIP switches as shown below. With the LS controller, the address has been factory-set to "0".

1356784

To set the LS controller to the talk only mode, set the 3rd DIP switch from the left (3 in the figure) to ON (down). With the LS controller, the talk only mode has been factory-set to OFF (up). * When the LS controller is set to the talk only mode, outputs are sent only

through CH1.

Use the 1st and 2nd DIP switches from the left (1 and 2 in the figure) to select the delimiter for data transmission.

• To set the delimiter to "LF":

Set the 1st and 2nd DIP switches respectively to OFF and ON (as shown below).

1356784

• To set the delimiter to "CR":

Set the 1st and 2nd DIP switches respectively to ON and OFF (as shown below).

1356784

• To set the delimiter to "CR + LF":

Set both the 1st and 2nd DIP switches to OFF (as shown below). * With the LS controller, the delimiter has been factory-set to "CR + LF".

1356784

EOI (End of Identify) can be output from the controller simultaneously when the delimiter is transmitted from the LS controller. Select the appropriate command to select how EOI is output. Thus, you can select whether EOI is output simultaneously when the delimiter is transmitted. In addition, you can output EOI alone from the controller without transmitting the delimiter from the LS controller.

Interface Messages

The responses to commands sent from the controller (computer, etc.) are as follows:

Command

CHAPTER 6 Optional Interface Boards

Listener-talker Functions

Setting Functions and Outputting Measured Values or Other Data

By sending commands from an external device (computer, etc.) to the LS controller, you can remotely set the various functions, or output measured values or other data from the LS controller. * For sending commands, ASCII character codes can be used.

The commands and formats are the same as those for the RS-232C. See section "RS-232C" in this manual.

The following commands can be used on the GP-IB in addition to those for the RS-232C.

Command Description

ES Transmits EOI (End of Identify) simultaneously when the

delimiter is transmitted. EO Transmits EOI (End of Identify) only. ER Cancels EOI (End of Identify) transmission. QS Enables SRQ (Service Request) transmission. QR Disables SRQ (Service Request) transmission.

K1 Outputs measured value of CH1 once when "GET" is

received.

K2 Outputs measured value of CH2 once when "GET" is

received.

K3 Outputs measured value of CH1 once and then that of CH2

once when "GET" is received.

Talk Only Mode

• When the power is turned ON, "ES", "QR", and "K1" (see the table above) are set.

• When "SRQ" transmission is enabled, bits DIO7 and DIO1 are set to "1" if the transmitted command has a syntax error.

Format:

Commands for setting functions CR *

With the RS-232C the delimiter for data output from the LS controller is "CR". However, the delimiter varies according to the setting when the GP-IB is used.

* The delimiter for commands sent from an external device (computer, etc.)

to the LS controller can be any of "CR", "LF", "CR + LF" and "EOI".

To set the LS controller to the talk only mode, set the 3rd DIP switch from the left (3 in the figure) on the back panel to ON. When the LS controller is set to the talk only mode, it only talks, continuously outputting the preset values. The listener function does not work.

Note that outputs are sent only through CH1 when the LS controller is in the talk only mode.

130 Transmits commands to LS controller.

"D": Sets "DIA" as segment mode. 140 "C0": Sets "CH1=X" as output channel mode. 150 "MN": Sets NORMAL as measurement mode. 160 "A9": Sets 512 as the number of measurements for

averaging. 170 "BM": Sets MOVE as averaging mode. 180 "X0": Allows LS controller to output measured value once. 190 Receives measured value once from LS controller. 200 Displays measured value. 210 Terminates program.

The above program provides the following status: Talker address for PC: 1 Listener address for LS controller: 0 Delimiter sent from LS controller: CR + LF Talk only mode of LS controller: OFF

Take the following precautions when using the LS controller.

Be sure to turn OFF the power of the LS controller to set the address or delimiter using the DIP switches on the back panel.

CHAPTER 7

HINTS ON CORRECT USE

General

GP-IB Interface I/O

• When noise interference may occur in the surroundings, connect the LS controller to an external device (computer, etc.) using an electromagneticinterference protection cable(s). Be sure to turn OFF the power of the LS controller before connecting it to an external device.

• Supply power to the computer or other device(s) before supplying power to the LS controller. If power is supplied to the LS controller first, it may malfunction due to noise occurring when another device starts up.

• Up to 15 devices can be interconnected using the GP-IB bus.

• The total cable length for connecting the devices should be 20 m or shorter, provided that it does not exceed "2 m x number of devices". Also, the length of each cable should not exceed 4 m. When 3 devices are connected, for example, the maximum total cable length is 6 m, and when 4 devices are connected, it is 8 m. (See the figure below.) To make long-distance transmission of data, use an appropriate signal transmission system instead of the GP-IB bus.

Connecting 3 devices

Targets

Measuring Conditions

Connecting 4 devices

LS LS

When using the GP-IB, set the address and delimiter applicable to the program to be executed or device(s) to be connected.

When the shape or glossiness of targets varies, measurement error may occur. In such a case, place a target of known dimension in the measuring area and calibrate the LS controller using CAL. (Two targets of different size are required.)

When the target is vibrating, measured values may vary significantly. In such a case, set the number of measurements for averaging to a larger number to ensure highly accurate measurement.

CHAPTER 7 Hints on Correct Use

Compatibility

Operating Environment

• With the LS series, the controller and scanning head are calibrated as a pair. To satisfy the specifications, therefore, be sure to combine a controller and scanning head having the same serial number.

• The transmitter and receiver are also calibrated as a pair.

• When using 2 scanning heads, connect them respectively to the specified connector port of the controller.

• Be sure to operate the LS controller in a place where the temperature is within a range between 0 and 45°C. (0 to 40°C for LS-3036/3060)

• Fluctuation in ambient temperature may cause measurement error. Always maintain the ambient temperature at a constant level. If the ambient temperature changes by 10°C, it takes approx. 60 minutes for the temperature distribution in the LS controller to become uniform.

• Be sure to keep the laser emitting surface (transmitter) and the laser receiving surface (receiver) free from any substance refracting light (such as water or oil).

• Blow off dirt or dust on the protective glass using clean air. If dirt or dust still remains, wipe it off using a soft cloth moistened with alcohol.

Countermeasures against Noise

• The protective glass can be replaced. See the figure below to replace the glass.

• Keep the wiring or connection cable away from high-voltage lines or power lines to prevent the LS controller from malfunctioning because of noise.

• Be sure to earth-ground the LS controller through the earth ground terminal (No. 19). Insulating the scanning head is also effective in reducing noise.

Fuse

Cooling Fan

When the fuse is blown, replace it with the following one: Midget fuse: F-7142 2A or equivalent

Do not block the cooling fan on the back panel. Blocking it will overheat the LS controller, causing malfunction.

CHAPTER 8

ERROR MESSAGES

H-Err

• If no scanning head is

connected to the controller or the connected scanning head malfunctions, an error message appears on the main display (CH1).

When 1 scanning head is used:

If no scanning head is connected or the connected scanning head mal functions, "H-Err" appears.

When 2 scanning heads are used:

When "HEAD2 ON" is selected using PRM: If no scanning head is connected to the HEAD1 connector port or the scanning head connected to that port malfunctions, "H-Err" appears.

If no scanning head is connected to the HEAD2 connector port or the scanning head connected to that port malfunctions, "H2-Err" appears.

When "HEAD2 OFF" is selected using PRM: Since the LS controller judges that no scanning head is to be connected to the HEAD2 connector port, "H-Err" appears.

• When "H-Err" or "H2-Err" appears, turn OFF the power. Then, make sure that the problem with the scanning head is removed or that the scanning head is connected properly, then turn ON the power.

• Turn OFF the power to cancel error message "H-Err" or "H2-Err".

P-Err

CALIB ERROR

When the transmitter and receiver are not aligned in terms of the optical axis, "P-Err" appears on the main display (CH1). Align them correctly.

Note: Ignore this message when using model LS-3033 SO.

When the LS controller is not calibrated correctly, "CALIB ERROR" appears on the main display (CH1). Carefully read the description for the calibration procedures, and calibrate the LS controller again using a proper gauge.

APPENDIX A

OPERATING PRINCIPLE

Laser beam emitted by semiconductor is reflected first by the polygonal mirror, then by the reflector mirror. Laser beam is scanned according to the rotational angle of the polygonal mirror during this process. Then, scanned beams pass through the collimator lens so that they run parallel to each other. These beams are directed at the target and converged onto a photodiode by another lens. The beams thus collected are converted into an electric signal corresponding to the light-dark pattern produced. The dimension of the target is determined by the width of "dark" region measured in terms of time.
