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.

First turn the focus adjustment control slightly to the left and right, to make sure that the Focus adjustment control is not at the upper or lower limit positions. Do not exert unnecessary force to turn the control at the upper or lower limit positions as this might damage the control. (For ZFX-SC90_/SC150_, the control stops turning at the nearest position. It turns free at the farthest position.)

Right

Do not install the Controller in the following orientations.

Wrong Wrong

• 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.

When attaching ferrite cores to the Controller's power cable, pass the cable once through each ferrite core.

Connecting the Controller to the Power Supply

Use a power supply that meets the following specifications.

Power supply voltage Approx. 24 VDC (21.6 to 26.4 VDC) Output current 1.5 A min. Recommended power supply S8VS-06024 (24 VDC, 2.5 A) Recommended electric wire size 0.14 to 1.5 mm2 (max. 1 m)

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-

nector (male) using a flat-blade screwdriver.

region (reference image)

When the measurement target moves out of position

The position of the measurement target is measured after the measurement region is shifted by the amount of position shift.

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.

Trouble Remedy Reference

Poor lighting The 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 contrast You 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.

Dark image You can raise the camera's sensitivity or lengthen the shutt er time to make the

image brighter.

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.
