Safety Precautions

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 BL600. 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.

	WARNING	Failure to follow instruction may lead to injury. (electric
		shock, burn, etc.)
		Failure to follow instructions may lead to product damage.

General Precautions

•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.

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 dam-
		aged.
		• 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		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 specifica-
		tions
		• 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

CAUTION		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 BL600. 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

1.4Safety Consideration

				Use of controls or adjustments or the performance of procedures other than those
		CAUTION
				specified herein may result in hazardous radiation exposure.
1
				The laser beam is not harmful to the skin. There is, therefore, no danger in expos-
				ing 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:
		WARNING
				• 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.

1.5Safety 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.

	CAUTION		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.

Connecting trigger input

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.

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 ( See pages 101.). It can also be 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.
