Panasonic A230 User manual

INTRODUCTION
Be sure to read this manual carefully before using this product to ensure proper use.
There are two manuals available for this Micro−Imagechecker A200 series: (1)
Micro−Imagechecker A−series Hardware Manual, and (2) User’s Manual. Please
read the manual appropriate for your needs.
Please ensure that the correct manual is read in accordance with objectives for use.

WARNINGS AND CAUTIONS
To be observed at all times
Read the manual carefully before installing, running, maintaining or inspecting the
equipment.
This manual uses two safety flags to indicate different levels of danger.
WARNING
If critical situations that could lead to user’s death or serious injury are assumed by
mishandling of the product:
−Do not use this product in areas with inflammable gas. It could lead to an
explosion.
−Exposing this product to excessive heat or open flames could cause damage to
the lithium battery or other electronic parts.
−Do not store a lens in the locations subject to direct sunlight. It could cause
smoke generation.
−Do not look at the sun through a lens. It could cause blindness.
−Always take precautions to ensure the overall safety of your system, so that the
whole system remains safe in the event of failure of this product or other external
factor.
CAUTION
If critical situations that could lead to user’s injury or only property damage are
assumed by mishandling of the product:
−Do not dismantle or remodel the product. It could cause excessive exothermic
heat or smoke generation.
−Do not touch the terminal while turning on electricity. It could lead to an electric
shock.
−Do not allow foreign matters such as liquid, flammable materials, metals to go
into the inside of the product. It could cause excessive exothermic heat or smoke
generation.
−Do not bend the cables forcibly, place a heavy object on them or bring them close
to a thermal appliance. It could lead to an electric shock or smoke generation.
−To prevent excessive exothermic heat or smoke generation, use this product at
the values less than the maximum of the characteristics and performance that
are assured in these specifications.
−Use the external devices for the emergency stop function and the interlock
circuit.
−Connect the wires or connectors securely. The loose connection could cause
excessive exothermic heat or smoke generation.
−Do not undertake construction (such as connection and disconnection) while the
power supply is on. It could lead to an electric shock.

PRECAUTIONS TO BE TAKEN BEFORE USING THE
IMAGECHECKER
Installation Environment
Avoid using the Micro−Imagechecker A200 in the following types of locations:
−Locations with direct sunlight or environmental temperatures that exceed a
range of 0°Cto50°C.
−Locations with a relative humidity exceeding a range of 35%RH to 75%RH or
that are subject to condensation due to dramatic temperature fluctuations.
−Locations with an atmosphere containing corrosive gases or flammable gases.
−Locations that subject the main unit to direct vibration or impact.
−Locations with a lot of fine particles, iron filings or salt.
−Locations likely to have contact with water, oil or chemicals.
−Locations with an atmosphere likely to contain organic solvents such as benzine,
paint thinner, and alcohol as well as strongly alkaline materials such as ammonia
and caustic soda.
Static Electricity
In a dry environment, there is a risk of accumulation of static electricity, so when there
is a need to touch the equipment, users should always discharge the accumulated
static by touching an earthed part of the equipment first.
Cleaning
Do not use thinners or similar solvents, as they may dissolve parts of the unit and
cause colors to run.
Power
Use an insulated power source with built in protection circuits. The controller power
unit uses non−insulted circuits, so if an irregular voltage is applied, there is a danger
that the internal circuitry will be damaged. If you use a power source that does not
use protection circuits, supply the power via a fuse or other protective device.
Power Sequence
−Arrange the power sequence so that the controller power source is turned off
before the input/ output power source.
−If you turn off the input/output power source before the controller power source,
the controller unit will detect an input signal level change and may not run
properly.

Before Switching On the Power
The following points should be checked before switching the power on to the
controller for the first time.
−Check that no extra wiring left installation, especially conductive materials, have
become attached to the board.
−Confirm that the power supply wiring and I/O wiring and power supply voltage
are correct.
−Firmly tighten all installation screws and terminal block screws.
Before Creating Type Data
Before creating product type data, be sure to initialize the environment settings and
all product type settings.
See 5. Environment and Product Types for more information about initialization.
General Cautions
−Use monitor, monitor cable, keypad, camera and camera cable models and
serial numbers specified by Panasonic Industrial Devices SUNX Co., Ltd.
Be aware that malfunctions, damage, destruction, etc. due to use of models or
serial numbers other than those specified by Panasonic Industrial Devices
SUNX Co., Ltd. will not be covered by the product warranty.
−Do not disassemble, modify, or change internal settings for the
Micro−Imagechecker unit or other equipment. Be aware that malfunctions,
damage, destruction, etc. due to disassembly, modification or use other than
that described in the manual will not be covered by the product warranty.
−Setting or changing items other than those that can be set or changed, as
described in the product manual and specifications, will result in damage. Be
aware that in the event that damage or destruction occurs due to settings or
changes, it will not be covered by the product warranty.
−After completing all of the settings for the Micro−Imagechecker, do not connect
the personal computer used for connecting the keypad, restoring or backup, in
order to prevent malfunctioning due to noise.
−Do not perform insulation resistance or pressure resistance tests between metal
areas of the power supply, input/output signal and connectors and the camera
case.

1. Character recognition is possible using the neural net
(character recognition checker)
See p. 7 −3.
−A maximum of five dictionaries (fonts) can be registered (comes standard with
two fonts: OCR−A and OCR−B).
−Compatible with connected letters and dotted letters.
−Cuts noise such as background patterns that can be mistakenly recognized as
characters.
−Recognized character strings are output serially.
−Compares the recognized character string with String Judgment (can be
changed by the external device.) to determine whether it matches or not.
01475B Character recognition
For details see page 7 −3.
2. Allows easy character−by−character inspection
(Character Verification Checker).
See p. 8 −3.
−Checks for missing characters, dirt, blurring, and incorrect
characters on a character−by−character basis.
−Just enclose the text with a marquee to extract and register each character as
a reference image for inspection.
−The Background Processing function eliminates unwanted noise (background
patterns etc.) that may otherwise be interpreted as characters.
Verify that these characters are
correct using the Character Checker

(Lead Inspection Checker).
See p. 10 −3.
−Inspects pitch, breakage and bending of IC and connector leads.

4. You can use a Gray Scale Edge Detection Checker and Gray Scale Window
Checker to measure the dimensions, determine the orientation and detect
missing leads.
See p. 11 −3 and 12 −3.
Measure the pitch using
a Gray Scale Edge Checker
Detect presence of the

accordance with the changes in the items to be inspected.
See p. 16 −29, 16 −34, and 16 −41.
9. Functions such as the Trap function, NG Display function, and Save Image
