Chapter 1 Laser Safety Precautions

CAUTION

WARNING

1.4 Safety Consideration

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

The laser beam is not harmful to the skin. There is, therefore, no danger in exposing arms or hands to the beam. The only 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.

Follow the safety precautions below to ensure operator safety:

• Operate the BL-600 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 BL-600 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 BL-600 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 BL-600 series.

• Stop laser emissions before cleaning the laser emission port.

Failure to stop the laser emission may expose eyes to the laser beam.

• Check the laser beam path.

To prevent exposure to the laser beam due to specular or diffuse reflection, install a screen which offers the appropriate reflectance and temperature characteristics to interrupt the reflected laser beam. Do not install the BL-600 series in such a way that the laser beam passes at eye height.

1.5 Safety Features Provided with the BL-600 Series

The BL-600 series is provided with the following safety features. Make sure these features function correctly before operating.

• Laser emission caution LED (LASER ON LED)

During laser emission, the LASER ON LED illuminates. The LED ON status can be checked through the laser protective glasses.

• Laser forced OFF command

Sending the laser forced OFF command (LOCK, see page 116) to the BL-600 can inhibit emission of laser beams. When working near the laser transmitter, be sure to use the laser forced OFF command to avoid looking into the laser beams.

When this command is selected, the bottom STABILITY LED flashes.

Power supply connections

Connect the 5 V DC power supply to the power supply connector of the BL-600 Series.

• Be sure to match the polarities of the power supply when soldering the connections. Reversing the polarities will damage the unit.

• Make sure that the power supply provides a stable 5 V DC ± 5%. If the power supply does not function in the above range, it can damage the unit.

Note1: Do not extend the power cable. A long power cable can cause a voltage

drop, preventing the BL-600 from starting properly. Note2: If the power supply is UL rated, it must provide Class 2 output.

5.1 Installation of the BL-600 Series

This section describes situations to check for before installing the BL-600 Series, and the installation procedure.

5.1.1 Situations to check for before installing the BL-600 Series

Check the following points before installing the BL-600 Series.

Avoid extraneous light from entering the transmitter/receiver of the BL-600 Series. Otherwise, the reading may fail or be unreliable.

Change the position of the sensor.

Remedy

Photoelectric sensor

Cut off the extraneous light.

If something interrupts the emitted or reflected laser beam, the reading may be unreliable.

Bar code

Light-shielding object

Reflected beam

Remedy

Change the position of the lightshielding object to ensure passage of the laser beam.

If the laser beam reflects the bar code at a right angle (specular reflection), the reading may fail or be unreliable.

* Since the BL-650HA/651HA emits a laser beam at an angle of 17°, tilting the

unit is unnecessary.

Remedy

15°

Be sure to apply the laser beam at some angle.

Chapter 5 Installation

If a strong reflected light enters the receiver of the BL-600 Series, the reading may fail or be unreliable.

Remedy

Metal surface

Cover the metal surface with black tape to avoid reflection.

If reflected light enters the receiver of another unit, the reading may be unreliable, because of mutual interference.

Place a lightshielding plate.

BL-600 Series

Bar code

Remedy

Keep a distance between the units.

If two or more bar code labels enter the laser beam at the same time, the BL-600 cannot be set to read a specific bar code.

5.1.2 Mounting angle and distance

The BL-600 Series must be installed so that the laser beam is applied at an angle of approximately 15° with reference to a line perpendicular to the target. This means that the BL-600/601/600HA/601HA must be tilted at an angle of 15°. Since the BL-650HA/651HA emits a laser beam at an angle of 17°, tilting the unit is unnecessary.

Refer to the read range and angle characteristics on pages 148 to 150 for the appropriate mounting angle and distance for the BL-600 Series.

Normally, the BL-600 Series provides the best reading stability when mounted at the following angle and distance.

6.1 Read Operation

This section describes the scanning methods of the BL-600 Series.

6.1.1 Scanning method

There are two methods to trigger the BL-600 Series to read bar codes: the “Level signal” method and the “One-shot signal” method. Select an appropriate method according to the application. Typically, the “Level signal” method is used. The following examples for these two methods use the “6.2.1 Single label read mode”. ➮

Level signal trigger

When the trigger input turns on, the BL-600 Series starts laser emission to read the bar codes. The laser turns off after the number of the bar code reading reaches the specified decoding match count. read data.

Reference 1: The BL-600 Series can read up to 4 types of bar codes without changing settings. ➮

Reference 2: Pressing the TEST switch lightly (for less than 2 seconds) serves as a trigger input (The laser turns on once.). ➮

See page 88

See page 49.

➮

See page 43.

The BL-600 Series then sends the

■ Timing diagram

*1 Set trigger input so that it stays on long enough for the laser beam to cover the

entire bar code.

*2 The BL-600 Series emits a laser after the trigger input exceeds the preset input

time. ➮

See the following note.

Note: The BL-600 Series has a built-in AGC (auto gain control) circuit. It requires a maximum of 3 scans (6 ms) to adjust the gain. Therefore, the BL-600 Series requires a maximum of 6 ms after the laser beam turns on before it begins to read the data.

*3 The communication time can be obtained from the following expression:

Data bits + (1: If parity is used) + Start/stop bit

*4 The length of time that the OK/NG output is on can be changed to any value

between the range of 10 ms to 2.55 s. ➮

*5 The OK/NG output turns on 5 ms after the bar code is read.

If the bar code cannot be read, the NG output is delayed by 5 ms plus the specified input time.

The BL-600 Series then sends the read data. The rest of the operation is the same as that for the “Level signal” method. Use the one-shot signal trigger when the one shot input time is extremely short or to fix the scanning time.

Reference 1: The BL-600 can read up to 4 types of bar codes without changing the bar code type setting. ➮

■ Timing diagram

*1 After the trigger input exceeds the preset input times, the laser begins to emit.

Trigger input minimum ON time:

5 ms (when the trigger input value is 2 ms) 15 ms (when the trigger input value is 10 ms)

Note: The BL-600 has a built-in AGC (auto gain control) circuit. It requires a maximum of 3 scans (6 ms) to adjust gain. The BL-600 generates a maximum of 6 ms delay until starting to read the data after the laser beam turns ON.

6.2 Read Modes

The BL-600 provides 4 types of read modes.

6.2.1 Single label read mode

The single label read mode allows the BL-600 Series to read only one bar code during one trigger input signal.

■ Data output timing

The BL-600 Series offers the following two data output modes to send data and output OK/NG signals. Select an appropriate mode according to the application. Typically, “After Read” is selected.

● After Read ➮ The BL-600 Series sends read data and outputs an OK/NG signal after a successful read. This is the operation described in “6.1.1 Scanning methods” on page 86 and

87.

● At trigger input ➮ The BL-600 Series sends read data and outputs an OK/NG signal at the following timings.

• For a “Level signal” trigger ➮

When the trigger input turns off

• For a “One-shot” trigger ➮

After the preset input time has passed

See page 42.

See page 86.

* The BL-600 Series continuously reads bar codes in the following periods.

• For a “Level signal” trigger ➮

See page 86.

During the trigger input signal

• For a “One-shot” trigger ➮

See page 87.

During the preset input time

* It is necessary to set the “Repeat-reading time” (➮

See page 42.

) to prevent the BL-

600 Series from reading the same bar code twice. Set the “Repeat-reading time” longer than the time it takes for the read bar code to go out of the field of the laser beam (100 ms to 25.5 s).

Note: The same type of bar code cannot be read during the specified repeatreading time. Different types of bar codes can be read continuously during the period.

* The OK output turns on every time the BL-600 Series reads a bar code. (Com-

parison to the preset data is not performed.) The NG output turns on after the trigger input turns off if the BL-600 Series fails to read any of the bar codes.
