1.Installation Environment
• Do not use the product in environ m ents where it can be exposed to inflamma bl e/ ex pl osive gas.
• To secure the safety of oper ation a nd maint enan ce, d o n ot ins tall the p roduc t cl ose t o high -v oltage de vices
and power devi ces.
• I nstall the product in such a way that its ven tilat io n holes are not blocked.
• Tighten mounting screws at the torque specified in this manual.
2.Power Supply and Wiring
• The voltage and AC power supply must be within the rated range (24 VDC ±10%).
• Reverse connection of the po w er supply is not allowed.
• Use the power supply within the rated load.
• H igh-voltage lines and power lin es must be wired separately from this product. Wiring them toge ther or
placing them in the sam e duct may cause induction, resulting in malfunction or damage.
• Use the product within the power supply voltage specified in this manual .
• U se a DC po wer sup ply with safet y measu res against high-vol tage spikes (sa fety extra lo w-voltage circ uits
on the secondary side).
• Tighten mounting screws at the torque specified in this manual.
3.Other
• Do not use this product in safety cir cui ts as sociated with nuclear power and human life.
• Do not disassemble, repair, modify, deform by pressure, or incinerate thi s pr od uct .
• Dispose of this product as indust rial waste.
• Connect the exclusive devices (Camera, Controller, Strobe Controller, Cable). The product might break
down or malfunction i f yo u use a part not included in the exclusive products.
• S hould you notice any abnormalities, imm ediately stop use, turn OFF the power suppl y, and contact your
OMRON representative.

Precautions for Correct Use
Observe the following precautions to prevent failure to operate, malfunctions, or undesirable effects on product
performance.
1.Installation Site
Do not install this product in locations subjected to the followin g conditions:
• Ambient temperature outside the rating
• Rapid temperature fluctuati on s (c ausing condensation)
• Relative humidity outside the range of 35 to 85%
• Direct vibration or shock
• Reflection of intense light (such as other laser beams, electric arc- w elding machines, or ultra-violet light )
• Direct sunlight or near heaters
• Strong magnetic or electric field
Also, do not install this product in locations subjected to the following conditions to ensure its protective
performance as described in the specifications:
• Presence of corrosive or flam m abl e gases
• Presence of dust, salt, or iron partic les
• Water, oil, or chemical fumes or spray, or mist atmospheres
2.Power Supply and Wiring
• When using a commercially av ai labl e switching regulator, make sure that the FG terminal is grounded.
• If surge currents are present in the power lines, connect surge absorbers that suit the operating
environment.
• B efore turning ON the power after the product is connected, make su re that the power supply voltage is
correct, there are no incorrect connections (e.g. load short-circuit) and the load current is appropriate.
Incorrect wiring may result in breakdown of the product.
• Before connecting/disc onnecting cables, make sure that the product i s turned OFF. The product may break
down if it is connected/di sc onnected while the power is ON.
• For cables, use only the exclusive products specified in this manual.
p.14, p.15
• Use only combinations of the Camera, Controller and Strobe Controller specified in this manual. Using other
combinations may cause malfunction or damage.
• D o not turn the power OFF in the following instances. Doing so will damage data that is in the process of
being saved.
- While data is being saved on t he Controller
- While data is being saved on the SD card
• T he LCD panel has b een mad e using prec ision tec hnolog y, and sometimes a few pixels a re missing i n the
panel. This is due to the structu re of the LC D panel, and i s not a malfunction.
• Do not remove the base from the Camera.
3.Maintenance and Inspection
Do not use thi nner, benzene, aceto ne or ker osene to clean the Camera and Con troller. If large dust particles
adhere to the Ca mera , us e a b lower brus h (u sed t o cl ean c amer a le nses) to blow them o ff. Do not use br eat h
from your mouth to blow the dust off. To remove dust particles from the Came ra, wipe gently wi th a soft cloth
(for cleaning lenses) moistened with a sma ll amount of alcohol. Do not use excessive force to wi pe off dust
particles. Scratches to the Cam er a m i ght cause error.
4.Ventilation Film
• D o not peel of the ventilation film or pr od it with a sharp-pointed object. Th is might impair its protective
structure.
• Do not cover the ventilation film. Doing so might cause the Came ra's front panel to cloud.

Important
• Do not use the 0.5-mm, 1.0-mm and 2.0-mm Extension Tubes attached to each other. Since these Extension Tubes
are placed over the threaded section of the Lens or other Extension Tube, the connection may loosen when more
than one 0.5-mm, 1.0-mm or 2.0-mm Extension Tube are used together.
• Reinforcement may be required for combinations of Extension Tubes exceeding 30 mm if the Camera is subject to
vibration.

Do not install the Controller in the following orientations.
WrongWrong
• Install the Controller so that the distance between the Controller and other devices is at least the dimensions shown
in the figure below to improve the ventilation.
BEFORE USE
• Keep the ambient temperature less than 50 °C. If the ambient temperature is higher than 50 °C, install a fan forced
cooling system or an air conditioner to keep the temperature lower than 50 °C.
• Avoid mounting on a panel, in which high-voltage emitting devices are installed to prevent ZFX-C operation from
being affected by noise.
• Allow at least 10 m between the Controller and power lines to keep noise at a low level in the operating environment.

Important
Use a DC power supply with countermeasures against high voltages (safe extra low-voltage circuits on the secondary
side). If the system must meet UL standards, use a UL class II power supply.
1 Loosen the t wo screws on the top of the Power con-

Clear Images Cannot be Obtained
Measurement som etimes cannot be pe rformed successfully (e. g. measurement image is dark or contrast is
low) depending on the charact eristics of the measur ement target. Sh arp images can be o btained by appl ying
filtering, or performing cor re ct ion and adjustment to remedy the trouble.
TroubleRemedyReference
Poor lightingThe recipe method light control settings can be used . You can set the lighting
just by selecting the image that meets your specific requirements from the
thumbnails of images automatically taken under different lighting patterns.
Low contrastYou can apply filters, such as "Sharpen", to the image to enhance the bound-
aries between shadow and highlight areas.
Uneven image• You can apply filters, such as "Smooth", to the image to smooth out
unevenness in the image.
• White parts of the image can be corrected to be reproduced appropriately
by adjusting the white balance.

Measurement Target Cannot be Measured Accurately
Due to Movement
When the measuremen t target is moving (e.g. its position or orientation are not fixed), it moves out of th e
preset measureme nt region, which prevents a ccurate measurement. The ZFX-C is provided wit h a "position
shift correction function" that corrects the position shift of mea sur em ent regions such as this befo re performing
measurement. The position shift correction function enables measurement targets whose position or
orientation is not fixed to be measured accurately.

Guidelines for setting detection size and detection interval
• Detection size
Determine the detection size roughly according to the size of the defect to be detected.
Setting a smaller detection size results in stronger detection sensitivity, while setting a larger detection size results
in weaker detection sensitivity.
(1)(2)
When a larger detection size is set, the difference with elements that are not defects decreases as the density of
elements other than defects also is included in the calculation at (2). In other words, the more background that is
included in the detection area, the weaker the detection sensitivity becomes.
• Detection interval
Determine the detection interval roughly according to the size of the defect and the detection size.
The larger the detection interval that is set, the shorter the processing time becomes.
When the detection area is greater than the defect, set a smaller detection interval.
When the defect is greater than the detection area, set a slightly larger detection interval.
When a small detection interval is set, elements overlapping the edge of the defect also are included in the comparison, and so the defect value decreases, which results in less stable detection of the defect.
