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

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

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.

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.

Analog Voltage Range

Displays sequentially the following 9 items: preset analog range, "LIMIT",
"DIGIT SUPPRESS", "HOLD", "BAUD RATE", "UNIT", "BUZZER", "HEAD2",
and "POSITION CHECK". Display the desired item first and make the
necessary changes. See the instructions below for making settings in each
item.

In this mode, measured value is converted into an analog voltage between

-6 V and +6 V. Match the desired measurement range and the above voltage
range. By matching these ranges, the measured value can be converted into
its corresponding voltage.

Determine the upper and lower limits (m) and (n) as shown below. These
values correspond respectively to +6 V and -6 V. This automatically deter­mines the conversion rate of the measurement range against the voltage
range.

Example of Operation You are to measure the diameter of round bars. The reference diameter is 10

mm, and you wish to convert a difference of 1 mm into 1 V.
In this case, first set 100.000 mm to 0 V. Then, to represent each 1 mm
change in diameter from the reference by 1 V, set the reference plus 6 mm to
+6 V and the reference minus 6 mm to -6 V. That is, +6 V = 16 mm and -6 V
= 4 mm.

• The LS controller is factory-set to +6 V = 60 mm and -6 V = - 60 mm.

•A range of 0.024 mm to 240 mm can be specified.

• Make sure that the value corresponding +6 V is greater than that for -6 V.

• When your reference value is an integer with no decimals, steps 4, 5, 8
and 9 can be omitted.

You can set the following 3 parameters in LIMIT:

• 3-step or 7-step differentiation

• Tolerance limits when 7-step differentiation is selected

• Comparator output type; Relay or open-collector (if the measured value is
above the upper limit or below the lower limit).

• Use FNC to set the tolerance limits for the measured value appearing on
the subdisplay (CH2). ➪

See P.32

CHAPTER 4 Functions and Controls

Tolerance Limits and
Comparator Output

■ 3-step differentiation

Choose the 3-step differentiation first, then set the tolerance limits using
LIMIT. When "ON" appears on the display, the comparator output is sent
through each of the relays and open-collectors (HIGH, GO, or LOW).

➪

See P.63, 64

Tolerance limit Condition Output

(Relay) (Open-collector)

HI < X HIGH HI1 (CH1)

HI

HI ≥ X ≥ LO GO GO (CH1)

LO

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).

➪

See P.63

Tolerance limit Condition Output

(Relay) (Open-collector)

HI3 < X HIGH HI3 (CH1)

HI3

HI3 ≥ X > HI2 HIGH HI2 (CH1)

HI2

HI2 ≥ X > HI1 HIGH HI1 (CH1)

LO1

LO1 > X ≥ LO2 LOW LO1 (CH1)

LO2

LO2 > X ≥ LO3 LOW LO2 (CH1)

LO3

LO3 > X LOW LO3 (CH1)

Note: X represents a measured value.

• It is possible to set the tolerance limits for both 3-step and 7-step differen­tiation. However, only the tolerance limits of the type of differentiation you
have selected are valid. Therefore, the comparator output is sent accord­ing to these limits.

24

• In 7-step differentiation, measured values can be correctly checked only
when the values assigned to the tolerance limits meet the following
condition: HI3>HI2>HI1>LO1>LO2>LO3
