Safety Precautions
WARNING
CAUTION
This instruction manual describes the operation and function of the BL-600. Read
this manual carefully to ensure safe use and maximum performance from your BL-
600. The BL-600 Series uses a semiconductor laser as light source. Before using
the product, see "Laser Safety Precautions" on page 1 to learn the safe and correct
method of using the BL-600 Series.
Symbols
The following symbols alert you to important messages. Be sure to read these
messages carefully.
Failure to follow instruction may lead to injury. (electric
shock, burn, etc.)
Failure to follow instructions may lead to product damage.
General Precautions
Note:
Reference:
• At startup and during operation, be sure to monitor the functions and performance of the BL-600.
• We recommend that you take substantial safety measures to avoid any damage
in the event a problem occurs.
• Do not open or modify the BL-600 or use it in any way other than described in
the specifications.
• When the BL-600 is used in combination with other instruments, functions and
performance may be degraded, depending on operating conditions and the
surrounding environment.
• Do not use the BL-600 for the purpose of protecting the human body.
Provides additional information on proper operation.
Provides reference information about the operation.

Warnings and Cautions Specific to the BL-600
CAUTION
• The BL-600 uses a 5 V DC power supply. Using a different voltage level may
damage the unit.
When using the KEYENCE power supply unit BL-U1, BL-U2, N-42 or N-48,
select the voltage level which can be supplied by the power supply unit. If a
nonconforming power supply is connected, the BL-600 may be damaged.
• Before connecting or disconnecting the cable, be sure to turn off any device
connected to the BL-600 Series. Otherwise, the BL-600 Series may be damaged.
• Do not disassemble or modify the BL-600 Series, as this may cause product
failure.
• Locate cables as far as possible from high-voltage lines and power lines.
Otherwise, generated noise may cause product failure or malfunctions.
• The BL-600 is a precision instrument. If the unit is dropped or shocked, it may
be damaged. Take due consideration when transporting or installing the unit.
Incorrect
• Do not hold the cables when carrying the units. The units may hit each other
and become damaged.

Environments and conditions for use
CAUTION
CAUTION
To use the BL-600 Series properly and safely, do not install it in locations with the
following conditions. Use of the BL-600 Series in improper environments may
cause fire, electric shock, product failure, damage, or malfunction.
• Locations where the BL-600 Series is exposed to direct sunlight
• Locations where the ambient temperature drops below 0°C or exceeds 45°C
• Locations where the relative humidity drops below 35% or exceeds 85%
• Locations where condensation occurs due to a sudden change in temperature
• Locations where a corrosive or flammable gas exists
• Locations exposed to dust, salt, metal particles, or greasy fumes
• Locations where the ambient light exceeds the range defined in the specifications
• Locations where the BL-600 Series is directly subjected to vibration or impact
• Locations where water, oil, or chemicals may splash the BL-600 Series
• Locations where a strong magnetic or electric field is generated
If abnormal conditions are encountered
If the following conditions are encountered, turn off the special power supply unit
immediately. Continuing to use the BL-600 Series under abnormal conditions may
cause fire, electric shock, or product failure.
Contact your nearest KEYENCE sales office or distributor (listed at the end of this
manual) for repairs.
• Water or foreign matter enters the BL-600 Series
• The BL-600 Series is dropped or the housing is damaged.
• The BL-600 Series produces smoke or an abnormal smell
Note 1: You cannot perform any operation for 5 seconds after turning ON the BL-
600. During this time, the motor rotation stabilizes. Wait for a while after turning ON
the BL-600, then start reading or another operation.
Note 2: The BL-600 Series has a housing rated as IP-65 (except for the special
power supply unit). It is not affected if water splashes it; however, a proper reading
may not be ensured if the transmitter/receiver is dirty (fingerprints, water, oil, or
dust). In such cases, wipe the dirt off with a soft cloth moistened with alcohol.

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.
1
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.
4
When this command is selected, the bottom STABILITY LED flashes.

Note: When the N-42 is used as a power supply unit, the communication type is
set to RS-422A, therefore the BL-600 Series cannot be connected directly to a
personal computer. To set the BL-600 Series with a personal computer, use an
RS-232C type power supply unit (BL-U1 or BL-U2).

3.1 Connecting BL-U1 and Wiring
This section describes the connection and wiring of the BL-600 Series and peripheral devices when the special power supply unit BL-U1 is used.
3.1.1 Connecting the BL-U1, AC power supply, and BL-600 Series
1. Plug the BL-U1 power cable into an outlet.
3

FG line
Do not use a power supply other than 100 to 240 V AC (50/60 Hz).
An improper power supply may cause product failure.
Note: If the noise conveyed through the FG line causes an LB-600 Series reading
error, do not connect the FG line.
2. Connect the BL-600 Series to the READER port of the BL-U1.

Chapter 3 Connection and Installation
The trigger input allows the BL-600 Series to start reading bar codes (turn on the
laser beam).
The trigger input is turned ON when 8.5 to 30 V DC input is activated between the
trigger input terminals.
The BL-U1’s power supply terminals for the sensor can be used as the power
supply input for the sensor.

■ Connection to a photoelectric sensor manufactured by KEYENCE
Connecting the OK/NG output
The OK/NG output is used to differentiate between acceptable and unacceptable
results based on a comparison with preset data
used to indicate whether or not the BL-600 Series successfully reads bar codes
when there is no preset data entered.
The OK/NG output is an NPN open-collector output.
