Safety Precautions

z Safety Precautions on Laser Apparatus

The "Hand-held Laser Barcode Reader BL-N70 Series" employs a visible red
semiconductor laser for its light source. This laser has a wavelength of 650 nm and is
classified as a Class 1 laser under IEC60825-1 (Safety of laser products). Do not
disassemble or modify the BL-N70 series.

Use of controls or adjustments or performance of procedures other than those

specified herein may result in hazardous radiation exposure. Exposure to laser
light may cause damage to eyes.

•

Do not look directly into laser light or reflected laser light from a mirrored
surface. Otherwise, eye injury may result. Laser light will not cause damage if
it strikes exposed skin, but laser light should not deliberately be aimed
towards a human body.

• Do not disassemble the BL-N70 series. The BL-N70 series does not

automatically stop emitting the laser when the reader is disassembled.
Therefore, if someone disassembles the reader, he/she may be exposed to
the laser beam and may suffer eye injury.

• Be sure to stop the laser emission before cleaning the portion of the laser

scanner where laser light is generated and received (emitter/receiver).
Otherwise, exposure to the laser may cause eye injury.

• Be careful of the path of the laser beam.

Be especially careful of reflected laser light from a mirrored surface.
Do not use the BL-N70 series where the path of the laser beam is at the
same height as that of the human eye.

Operating Precautions

z Operations

• Do not use a voltage other than 5V DC with the BL-N70 series. Doing so may

lead to breakdown on the unit. When using the dedicated power sources BL­U1, BL-U2, or N-42 use a power supply within the appropriate range for each
communication unit.

• Be sure to turn the power off to devices attached to the BL-N70 series when

you plug or unplug the cables. Failure to do so may cause damage to the BL­N70 series.

• Do not disassemble or modify the BL-N70 series. Doing so may lead to

breakdown on the unit.

• Keep the cables away from high-tension cables or power sources. Otherwise,

noise could cause malfunctions or accidents.

• The BL-N70 series passes the drop impact resistance test, but take care not

to expose the unit to excessive shock.

• Do not hold the BL-N70 series by its cable. The unit may become damaged.

z Cleaning

• Do not allow water, oil, dust, or other foreign substance to stick to the laser

emitter/receiver. This may cause read errors. When the BL-N70 series
becomes dirty or stained, clean the surface using an eyeglass cleaning cloth
or a soft cloth that has been dampened with a specialty cleaner for plastics
that can handle acrylic.
(Substances such as ethanol can make acrylics cloudy.)

z Operation Environment/Conditions

CAUTION

To use the BL-N70 series correctly and safely, avoid installing it in the following
locations. Failure to do so may cause fire, electric shock, damage, accidents, or
malfunctions.

• Locations where the BL-N70 series is exposed to direct sunlight

•

Locations where the ambient temperature drops below 0°C or exceeds +40°C

•

Locations where the ambient humidity goes outside of the range of 35 to 85%RH

• Locations where the temperature changes rapidly, causing condensation

• Locations where there are flammable or corrosive gases

• Locations where there is a large amount of airborne dust, salt, iron, and

greasy fumes

• Locations where the ambient lighting exceeds the regulation range

• Locations where the unit may be directly subjected to vibration or impact

• Locations where water, oil or chemicals may splash onto the unit

• Locations where a strong magnetic or electric field is generated.

z Procedures during Malfunction

Turn off the dedicated power source immediately in the following cases. Using the
unit in abnormal conditions could cause fire, electric shock, or accidents. Contact
your nearest KEYENCE office (listed at the end of the manual) for repair if :

• chemicals, debris, or liquids, including water, enter the BL-N70.

• the BL-N70 is damaged.

• smoke or abnormal odors are emitted from the BL-N70 series.

z Duplicate prevention function

When the laser light runs for a period of time, the reader may accidentally read the same
barcode two or more times. This function will ignore the second reading and any later
readings.

• Factory setting: 0.3 s (This value can be changed. page 4-16)

• After a barcode had been read correctly, to read the same barcode again, either turn off

the laser light temporarily or distance the barcode from the reading window for about
one second to clear the reread prevention time.

z Digit Limit Function

This function will only scan barcodes of a fixed number of characters. Any barcode with
more or fewer characters will not be read and data will not be sent. By default, there are
no limitations.
The two limit functions are:

• Limit All: Assigns a fixed limit to ALL symbologies (ITF, UPC, etc.)

• Limit individual: Assigns a fixed limit to selected symbologies.

z Seven tone buzzer

• The buzzer that signals the completion of reading can be muted or set to seven different

tones ( page 4-14).

The buzzer patterns change according to the following conditions.

• During reading : When reading is complete, the buzzer sounds once.

• During program mode : The buzzer sounds 1 to 3 times depending on the settings.

During program mode, an error alarm sounds when a barcode
other than the specified target code is read.

• The laser will continue to emit for a set period of time after the trigger switch is released.
During this time, press the trigger switch again to read a barcode. The laser will continue
to emit for a set period of time starting from the point when the trigger switch is released.

• The factory default set time is 0.5 s. The setting can be changed ( page 4-13).

• Even if the trigger switch is pressed down, the laser light will automatically stop emitting

if a barcode is not read for a period of time (about one minute).

Programming BL-N70 Settings

Out of the box, the BL-N70 family of handheld barcode scanners is
ready to read barcodes. However, your application may require
modifications to the factory default settings to function or
communicate properly. Changes to the BL-N70 family program
settings are made by scanning the setup codes found in this chapter.

4-1 Using Program Mode

Program mode allows you to make changes to the BL-N70 family default settings. To initiate
program mode, the Start / End Programming Mode barcode must be the first code scanned
after power-up. If additional codes have been scanned, you must reset power to the
scanner.

Setting procedure

Use the following procedure to change the settings.

Scan the barcode for "Start / End Programming Mode."

1

The buzzer sounds three times, the laser light begins emitting, and the reader
enters program mode.

4

Programming BL-N70 Settings

Scan all of the barcodes for items that you want to change.

2

To initialize the unit to factory settings, read the "Initialize" barcode.

To save the settings and return to RUN mode, read the barcode for

3

"Start / End Programming Mode."

The buzzer sounds three times, the laser light stops emitting, and the reader
exits program mode.

To enter program mode, the "Start / End Programming Mode" barcode must be

•

read directly after turning on power to the reader. To perform normal reading
operations, turn off and on the power to the BL-N70 series.

Note

• During program mode, an error alarm sounds when a barcode other a program

barcode is read. Do not read a barcode other than a program barcode during
program mode.

• If a program barcode is not read for about one minute during program mode, a

buzzer sounds three times, the set information is lost, and program mode ends.
Restart the settings from the beginning to make changes.

Setting the laser off time

After reading the "Trigger switch mode" barcode above, use the following method to
set the laser off time setting.

• To set the time, read three barcodes for the decimal program code ( page 4-24).
The time can be set between 500 and 15,000 ms in 100 ms intervals.

Example: To set the trigger off time to 3 seconds (3000 ms):

1. Read the "Laser off time setting" barcode.

2. Read the decimal program code "0." The buzzer sounds once.

3. Read the decimal program code "3." The buzzer sounds two times.

4. Read the decimal program code "0." The buzzer sounds three times.

Decode Match Count settings

When the trigger is activated, the BL-N70 laser scans approximately 76 times per second.
By default, the BL-N70 must decode a barcode 2 times within a trigger period before it is
considered valid and data can be sent. If poor print quality, or other conditions are causing
problems with decode reliability, try setting the Decode Match Count to a number higher than 2.

If your application requires more speed, you can set the Decode Match Count to 1.

For most applications, the default value of 2 is sufficiently fast and reliable and does not need to
be changed.

can be set between 50 and 6350 ms in 50 ms intervals. (The factory default time is 300
ms.)

Example: To set the reread prevention time to 1 second (1000 ms):
1000ms/50ms=20

1. Read the "Start reread prevention time settings" barcode.

2. Read the decimal program code "0." The buzzer sounds once.

4-7 Digit Limit Function Settings

The Digit Limit Function is useful if you are scanning barcodes with a certain number of digits
n and want to ignore barcodes with more or fewer digits.
Depending on the application, the BL-N70 family offers two Digit Limit Options:

z LIMIT ALL

Applies to ALL enabled symbologies. All barcodes of length n characters, will be
scanned. Any barcode with < > n characters will be ignored.
To set the number of digits, scan three decimal barcodes from page 4-24.

z LIMIT SELECT

Up to 7 different limits can be activated at the same time. For example, you can limit all
ITF codes to 14 digits. At the same time, you can limit all Code 128 barcodes to 26
characters. All ITF codes <>14 digits are ignored. All Code128 codes <>26 digits will be
ignored.

Conditions:

• Can set up to 7 total limits

• Can use multiple limits for same symbology:

example: Allow Code 39 barcodes of length 7 to 10 digits (4 limits used; 7, 8, 9, 10)

• Individual limits must be scanned in order, starting with limit #1 codes first, then #2 and
so on. Do not jump around.

Example 1: Read 10 digits for CODE39 and 14 digits for ITF
Limit #1 settings

1. Read the "Limit #1 – digit settings" barcode.

2. Read the decimal program codes "0," "1," and "0."

3. Read the "Limit #1 – symbology settings" barcode.

4. Read the decimal program codes "0," "8," and "0."

Limit #2 settings

5. Read the "Limit #2 – digit settings" barcode.

6. Read the decimal program codes "0," "1," and "4."

7. Read the "Limit #2 – symbology settings" barcode.

8. Read the decimal program codes "0," "8," and "2."
