Introduction

Precautions for Correct Use

Please observe the following precautions to prevent failure to operate, malfunctions, or

undesirable effects on product performance.

(1) Installation Site

Do not install the 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

Introduction

(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 the Sensor Head, make sure that the Smart Sensor is turned OFF. The Smart Sensor may break down if the Sensor Head is connected or disconnected while the power is ON.

• Use the Extension Cable (provided) for extending the cable between the Sensor Head and Sensor Controller. The total length varies according to the type of Extension Cable.

- Extension Cable: ZS-XC_A: within 10 m (including Sensor Head cable. Extension

Cable cannot be daisy-chained.)

- Extension Cable: ZS-XC_B(R): within 22 m (including Sensor Head. Up to two

Extension Cables can be daisy-chained.)

- Extension cable for a long distance ZS-XC_ _CR: within 27 m (including Sensor

Head. Digital equalizer ZS-XEQ and the Digital equalizer connection cable ZSXC02D are necessary. The extension cable cannot be daisy-chained.)

• The cable may break at locations when it is made to bend. So, use the robot cable type Extension Cable (ZS-XC5BR, ZS-XC_ _CR).

• Use only combinations of Sensor Heads and Sensor Controllers specified in this manual.

Introduction

Introduction Precautions for Correct Use

(3) Orientation when Installing the Sensor Controller

To improve heat radiation, install the Sensor Controller only in the orientation shown below.

Do not install the Sensor Controller in the following orientations.

(4) Warming Up

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

(5) Maintenance and Inspection

Do not use thinner, benzene, acetone or kerosene to clean the Sensor Head and Sensor Controller. If large dust particles adhere to the front filter of the Sensor Head, use a blower brush (used to clean camera lenses) to blow them off. Do not blow the dust particles with your mouth. To remove smaller dust particles, 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 on the filter may cause errors.

(6) Sensing Objects

The product sometimes cannot accurately measure the following types of objects: Transparent objects, objects with an extremely low reflection factor, objects smaller than the spot diameter, objects with a large curvature, excessively inclined objects, etc.

(7) Effect caused by peripheral lights

Do not install the Sensor Head in a place where strong light hits the laser emitter/ receiver section of the Sensor Head. Also, if a workpiece 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.

(1) Enhanced Variation of Sensor Heads

Suitable as a high-end displacement sensor, it supports a wide range of Sensor Heads. You can perform a stable measurement using a Sensor Head that is suitable for the workpiece, from 0.001 µm ultra-high-resolution type to 1500-mm ultra-long-range type.

(2) Sensor Controller Incorporating Multiple Functions

For one sensing condition, it incorporates a multi-task function that holds up to a maximum of four kinds of measurement processing as a “task.” Because you can measure any characteristic point for each task, you can measure and judge multiple characteristic points simultaneously.

1-2

Example: Measure the height and surface fluctuation simultaneously.

Surface fluctuation (TASK2)

Height (TASK1)

(3) Setting Support Software for Personal Computer “SmartMonitor ZS”

It displays data and specifies the settings for the controller that is connected via “SmartMonitor ZS” bundled with the Sensor Controller (ZS-HLDC_1A). You can easily check the sensing status and specify the settings in more detail, which cannot be done using a controller.

If you use “SmartMonitor ZS Professional,” which is sold separately, you can do logging for a

measured value.

Installing near walls

Measurement errors can be reduced by installing the Sensor Head with the line formed by the emission and reception axes parallel to the wall, and painting the wall with non-reflective black paint.

Wrong Right

Rotating objects

When measuring rotating workpieces, you can minimize the influence caused by vibration of the rotating object and positional shifts by installing the Sensor Head with the line formed by the emission and reception axes parallel to the axis of rotation.

Wrong Right

Measuring stepped workpieces

Wrong Right

Effect caused by peripheral lights

Do not install the Sensor Head in a place where strong light hits the laser emitter/receiver section of the Sensor Head. Also, if a workpiece 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.

Reset input This resets all executing measurements and outputs. While a reset is

being input, judgment output conforms to the non-measurement setting. If this reset input switches ON while the hold function is used, the state in effect before the hold function was set will be restored.

Status indicators p.8-39

LD-OFF input If this LD-OFF signal is set to ON, the laser will stop emission, causing

a light amount error. While LD-OFF is being input, judgment output conforms to the non-measurement setting.

Zero reset input This is used to execute and clear a zero reset.

Bank input A, B This is used for switching banks. Specify the bank No. in combinations

of A and B. However, if the bank mode is set to [THRESH], the bank cannot be switched at the external signal input because the number of banks increases to 32.

You can use the two modes appropriately according to the measurement details; for standard measurement, you can use “Single-Task mode” that can be set easily, and when you need detailed settings, for example when you measure and judge multiple characteristic points simultaneously, you can use “Multi-Task mode”. In “Multi-Task mode”, four tasks are provided. You can measure and judge multiple characteristic points simultaneously because you can measure the desired characteristic point such as peak, bottom, and average for each task.

If you cannot perform measurement in the provided measurement modes, use Custom mode. You can change additional lines and exposure time, so that a measurement can be performed under conditions suitable for the surface status of the workpiece.

Set in the order of [LINE] → [EXPOSE] → [SKIP].

If you set an additional line, its exposure time is automatically determined. If the light amount is still

insufficient, set the exposure time. When [SKIP] is set to ON in this state, the effective line width is

doubled.

X FUN Mode-[SENSING]-[MODE]

Setting Description

CUSTOM

LINE (number of additional lines)

Set this item to make it mode difficult (increase the number of additional lines) for measurement to be influenced by the state of the workpiece surface, or to measure at a single pinpoint on the workpiece (reduce the number of additional lines). Range: 1 to 200 (The maximum number of lines changes according to the exposure time setting.)

Setting GAIN

You can set the CMOS gain so that even workpieces having an extremely low amount of reflected light or workpieces having a large tilt can be measured stably.

The measurement resolution sometimes drops when a large gain is set. Also, this function increases the

gain on the light receiving side. Therefore, please note that the Sensor Controller can be easily affected

by ambient light.

• The same sensing mode must be set to each controller when the mutual interference prevention mode

is used. When [HI-SPEED] or [CUSTOM] is selected as the measurement mode, the same conditions

must be set. Setting different conditions will result in a sampling cycle on each controller and mutual

interference can no longer be prevented.
