Introduction

Precautions for Correct Use

Always observe the following precautions to prevent operation failures, malfunctions, and adverse effects
on performance and equipment.

1. Installation of the bar code reader

 The bar code should be mounted in a place:

• where is not subject to direct sunlight (indoor use),

• without any corrosive gas, dust, metallic powder or salt content,

• where operation temperature does not exceed the specified range,

• where temperature change is not rapid, without dew condensation (within the

specified value),

• where humidity change is not rapid, without dew condensation (within the specified value),

• where vibration or shock does not reach to the bar code reader directly (within the

specified value),

• and without any droplet of water, oil or chemical agent.

Introduction

2. Power supply

• Apply voltage to be +5 VDC ±10 % at the connector of the bar code reader side.

• Used cable should be 0.3 mm

or resistance is too huge, voltage may be decreased due to fluctuation of
consumption current of the bar code reader.

• Be careful so that noise or switching surge of relay is not applied on +5 V power

voltage supplied to the bar code reader.

• To suppress influence such as noise, use direct current of insulation transformer, not

auto transformer.

3. Wiring

• Extension length of the RS-232C line (SD, RD, SG) should be up to 15 m.

• For trigger and power line, use a cable with 0.3 mm

2

or more and extension length

should be up to 5 m.

• Wiring should avoid approaching to a high-power heavy electric current wire.

• Check the polarity of terminals and be careful of faulty wiring.

• Avoid reverse connection of power supply or connection to alternating current.

• Turn off the power switch before connecting or disconnecting a connector.

• Use a wrist strap etc. to avoid electrostatic charge when you touch terminals and

signal lines, to avoid damage due to static electricity.

4. Installation

• When using the bar code reader, fix it to the associated mounting bracket.

• When inductive noise is generated at the mounting bracket, attach an associated

insulation board. Use the associated screw to mount the insulation board.

• Incline the bar code reader about 15 ° to read the target bar code.

• Do not apply stress on the cable when mounting and using.

• Distance and angle allowed to read differs according the bar code. Check if the used

bar code can be read actually, before mounting.

5. Timing input with photo-electronic sensor

When taking timing with the photo-electronic sensor, mount the bar code reader so that
the footlight beam of the photo-electronic sensor does not spot directly on the reading
window of the bar code reader or on the bar code.

Introduction

7. Mutual interference

When mounting the bar code readers side-by-side, laser beams may interfere reading
each other. The bar code readers should be placed far enough not to affect reading.

Bar code

Introduction

8. Bar code label

• The height of the bar code should be more than the luster scan width (max. 10 mm)

and use a label considering attaching error.

• When reading bar code, margin is necessary on the both sides of the bar code. Set

the label so that margin parts do not hide. A space of one character or more and 2.5
mm or more is necessary of both right and left side of the label. (Rough standard: 12
or 13 times or more of the narrow bar width)

9. To improve reading reliability

• When the digit is determined, designate the digit to use the bar code.

• Use the modulus check (addition of check digit).

• Bar codes other than the reading object should be set to reading prohibition.

p.61

10. Maintenance and check

• Check for any dust or dirt on the reading window regularly. When it is dirty, wipe with

a dry, soft and clean cloth. Do not use solutions such as thinner.

• Handle with care, not to apply strong shock such as dropping.

A bar code reader is a device to read a bar code attached on a product and transfer the
information to upper equipment.
Various types of information can be managed efficiently by using it combining with PC and
programmable controllers.

Problems on site Bar code solution!

Work data are recorded on papers.
> Reading and writing mistakes and

distribution of workers exist.

> Formats are difficult to learn because various

kinds are produced in small numbers.

Cost should be as cheap as possible as
the product price is low.

Register product numbers and setting on PC
and programmable controllers beforehand and
import a product number only by reading a bar
code. Input mistake or distribution of workers
are eliminated.

Reading starts by applying reading trigger
from outside.
This system is mainly used when operation.

When the external trigger signal is turned
on, laser radiates and starts reading. The
"Trigger controlled system" reads during
the trigger is ON, and the "Effective
duration designation system" reads only the
effective duration (*1) which is set
beforehand after the trigger is ON.

The upper equipment sends the
communication command and the laser
beam radiates to start reading. After
receiving the command, it reads only for the
effective duration (*1) which is set
beforehand.

Press the TEST button once to read once.
Handy to use to check if the reading
condition setting is appropriate.

When the reading succeeds, the data is
output and ends reading automatically.

Reads bar codes continuously during the
trigger is ON or effective duration (*1).
When the first reading is completed, data is
once output and while reading the same
bar codes continuously, no output is made.
Outputs newly only when the data differ
from the adjacent bar code.

Reads bar codes continuously during the
trigger is ON or effective duration (*1).
Outputs data continuously even for the
same bar code.

During the power is turned on, laser is
radiated all the time, to be able to read
any time. This system is mainly used at
installation and system testing.

code.

Reads continuously and outputs the data
continuously.

*1 Effective duration of reading

When the trigger input method is external trigger signal effective duration designation system or RS-232C
command, effective duration setting is required beforehand. Effective duration is set by combining "effective
duration" from 0 to 10 sec. and "minor setting" from 0 to 750 ms.

E.g. 1: When you want to set the effective duration to 2.5 sec., set the effective duration to 2 sec. and the

minor setting to 500 ms.

E.g. 2: When you want to set the effective duration to 0.7 sec., set the effective duration to 0 sec. and the

minor setting to 700 ms.

E.g. 3: When you want to set the effective duration to 10.0 sec., set the effective duration to 10 sec. and the

minor setting to 0 ms.
