Do not install the Controller in the following orientations.

Important

BEFORE USE

• 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.

• 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 environ-

ment.

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 sometimes cannot be performed successfully (e.g. measurement image is dark or contrast is low) depending on the characteristics of the measurement target. Sharp images can be obtained by applying filtering, or performing correction 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 shutter time to make the

image brighter.

Measurement Target Cannot be Measured Accurately Due to Movement

When the measurement target is moving (e.g. its position or orientation are not fixed), it moves out of the preset measurement region, which prevents accurate measurement. The ZFX-C is provided with a "position shift correction function" that corrects the position shift of measurement regions such as this before performing measurement. The position shift correction function enables measurement targets whose position or orientation is not fixed to be measured accurately.

Registration of Graphic Search models differs from registration of Pattern Search models in that the model profile is registered. In model registration, the profile of the target image can be traced automatically. Also, the various tools can be used to adjust how much of the profile is picked up, perform free drawing, and interpolate and delete profile lines.

1 Select [Auto] and enclose the area in which the

profile is to be traced.

2 Select [Auto] displayed on the lower left of the

screen for region settings.

The profile is traced.

3 Adjust the profile lines.

How much of the profile is picked up can be adjusted by selecting [Up] or [Down] after the profile is traced.

[Up]: Selecting this setting multiple times makes noise

(only low-contrast noise) more difficult to pick up. This setting is effective when lots of noise is picked up. Delete high-contrast noise with the [Erase] tool.

[Down]:Selecting this setting multiple times makes the

profile easier to pick up. This setting is effective when the profile to be detected is not picked up.

4 If the profile is partially clipped, trace by [Free],

[Box], [Ellipse] or [Line].

When [Free] is selected, the profile can be drawn with the touch pen. The profile of automatically picked up images can be traced and interpolated as desired with the touch pen.

size inside the measurement region. The average density is calculated for each detection area. The average density of the detection area is then compared with the surrounding average density, and the defect position is detected by how much the average density differs with the surrounding area. The difference with the average density that was the largest is output as the defect value.

Places having a defect value lower than the noise level are removed as the noise component, while places having a defect value higher than the noise level are counted as defect positions.
