ZG User’s Manual

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 following conditions:

• Ambient temperature outside the rating

• Rapid temperature fluctuations (causing condensation)

• Relative humidity outside the range of 35 to 85%

• Presence of corrosive or flammable gases

• Presence of dust, salt, or iron particles

• Direct vibration or shock

• Reflection of intense light (such as other laser beams or electric arc-welding

machines)

• Direct sunlight or near heaters

• Water, oil, or chemical fumes or spray

• Strong magnetic or electric field

2.Power Supply and Wiring

• When using a commercially available 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.

• Before turning ON the power after the product is connected, make sure 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/disconnecting devices, make sure that the Sensor/Controller is

turned OFF. The Sensor or Controller may break down if it is connected/disconnected

while the power is ON.

• Use the extension cable sold separately for extending the cable between the Sensor

and the Controller.

p.17

• Use only combinations of the Sensor and Controller specified in this manual.

• Before turning the Controller ON, connect the Sensor. If the Controller is turned ON

without the Sensor connected, the Controller’s screen will remain dark and messages

cannot be read.

ZG User’s Manual

3.Warming Up

After turning the power supply ON, allow the product to stand for at least 30 minutes before use. The circuits are still unstable just after the power supply is turned ON, so measurement values may fluctuate gradually.

4.Maintenance and Inspection

Do not use thinner, benzene, acetone or kerosene to clean the Sensor and Controller. If large dust particles adhere to the filter on the front of the Sensor, use a blower brush (used to clean camera lenses) to blow them off. Do not use breath from your mouth to blow the dust off. To remove dust particles from the Sensor, wipe gently with a soft cloth (for cleaning lenses) moistened with a small amount of alcohol. Do not use excessive force to wipe off dust particles. Scratches to the filter might cause error.

5.Measurement Target

The measurement target is a non-transparent object. The sensor cannot detect the following types of objects accurately: materials with extremely small reflectances, objects smaller than the beam diameter, objects with large curvatures, or objects tilted to a large degree.

6.Effect of Peripheral Lighting

Do not install the Sensor in a place where strong light hits the laser emitter/receiver section of the Sensor. Also, if a measurement target has a shiny surface, the light from the lighting will be reflected and a malfunction may occur. In such a case, prevent reflection by, for example, covering the light to stop reflection.

A cross-section shape of the measurement object displayed on screen is called a “profile.” Profiles are displayed on screen as a yellow line. In the RUN/ADJ modes, the measurement state can be visually checked by these profiles. Also, in the FUN mode, profiles can be used to set the measurement conditions. Height measurement items are already set as the default, so it is possible to know immediately the detection status of the Sensor by setting the operation mode to the RUN mode.

On the ZG series, measurement points in the height and width directions are measured on the vertical (Z-axis) and horizontal (X-axis) axes, respectively. Measurement values are displayed as numerical values prefixed with a + (plus) or - (minus) sign depending on the coordinate position.

Relationship between Tasks and Bank Data

You can register up to eight tasks to a single set of bank data. Up to 16 sets of bank data can be set and saved on the ZG series, so you can prepare up to 128 measurement patterns by combining bank data with task settings. Combinations of bank data and tasks become the measurement and judgment condition settings.

Run in EXP mode

< STD mode >

This mode is designed for ease of operation, so its setting and adjustment ranges are limited. Setting in this mode comprises only three steps, so you can start measurement immediately.

< EXP mode >

This mode allows you to set all adjustment functions. You can use this mode to execute advanced measurement processing, such as measurement of image angle, calculation of processing items and selection of characteristic points.

The STD and EXP modes are switched by the “mode switch” on the front of the controller. Two modes cannot be selected simultaneously during menu operation as the mode is fixed by the mode switch.

Image Adjustment

Adjusting Sensitivity

The sensitivity of the Sensor can be adjusted so that shapes are accurately captured even if the shape, color, material, etc. of the measurement target is influenced. The default setting is [MULTI].

Sensitivity Adjustment Functions of the ZG Series p.159

FUN mode-[MEAS]-[IMAGE]-[LD-POWER]

Setting value Description

MULTI Measurement is performed with the sensitivity adjusted for each

individual line in the measurement region. This method is suitable when the brightness of the measurement target surface fluctuates to a large degree.

AUTO Measurement is performed with the sensitivity adjusted

automatically based on the sensitivity information in the measurement region. This method is suitable when the brightness of the measurement target surface is uniform.

FIXED Measurement is performed with the sensitivity fixed.

This method is suitable when accurate measurements cannot be made at the [AUTO] setting, for example, for lines on which measurement targets of various colors are fed alternately.

Important

[MULTI] is effective as a sensitivity adjustment function only when measuring stationary measurement targets. When the measurement target cannot be made stationary, use [AUTO] or [FIXED].

Setting the interpolation method

This is used for interpolating between data in areas where profile data is missing (areas where measurement is not possible). If there are lines where the measurement target cannot be measured due to different degrees of reflectance or other causes, the data of such lines can be obtained by interpolating between the data acquired for the lines that allow measurement as desired.

Example: Profile output result when there are areas where measurement data cannot be

obtained
