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%

• Direct vibration or shock

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

• Direct sunlight or near heaters

• Strong magnetic or electric field

Also, do not install this product in locations subjected to the following conditions due to the degree of protection specified in the ratings:

• Presence of corrosive or flammable gases

• Presence of dust, salt, or iron particles

• Water, oil, or chemical fumes or spray

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 (receiver) and the Controller.

p.20

3. Warming Up

After turning the power supply ON, allow the product to stand for at least 10 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.

Mounting and Connecting Devices

Mounting the Sensor

Never look into the laser beam. Doing so continuously will result in

visual impairment.

Do not attempt to dismantle, pressurize, or incinerate the product. Doing

so may cause the laser beam to leak, resulting in the danger of visual

impairment.

Important

If a measurement target has a shiny surface, reflected light might adversely influence adjacent Sensors. Mount the Sensor so that it is not influenced by reflected light.

Important

Before connecting/disconnecting the Sensor, make sure that the Controller is turned OFF. The Controller may break down if the Sensor is connected or disconnected while the power is ON.

1 Insert the receiver connector into

the Controller connector.

Note

When the measurement cycle has been changed to the high-speed mode (FAST), wiring of the sync wires is not required. Note, however, that the Controller becomes more susceptible to the influence of ambient light in this case.

2 Connect the Controller and

Sensor sync wires.

Controller sync output wire : yellow Emitter sync input wire : red

Important

The Controller's default mode is the standard mode. Measurement is not possible without the sync wires connected.

Connect the power wire (brown) and the GND wire (blue) of the emitter and the Controller I/O cable.

Note

The following power supply is recommended:

• S8VS-03024 (24 VDC, 1.3 A)

Important

Do not mount the Controller in such a way that a load is steadily applied on the connector, for example, with tension applied to the cables.

Correcting Analog Output Values

Discrepancies may occur between the analog output current (or voltage) values set on the Controller and the actual measured current (or voltage) values due to the conditions for the connected external device or other factors. The analog output correction function can be used to correct this discrepancy. The output values are corrected by entering the correction value for the current (or voltage) values for any two points.

Important

Set scaling beforehand, and select current output or voltage output. Also, connect the analog output wire to an external ammeter or voltmeter.

The measurement cycle is 1.5 ms.

This is the time required until the measured data is applied. (max. 1 ms)

This is the time until the Controller starts analog output after completion of measurement. (100 µs)

This is the time until the Interface Unit starts binary output after completion of measurement. This time differs according to the number of Controllers connected to each other. (0.5 ms x number of connected Controllers + 0.5 ms)

This is the time in which the Interface Unit outputs the binary data. This time can be changed. (1 to 500 ms (default value: 1 ms))

This is the time that the GATE signal is ON. This time differs according to the currently set binary output cycle. (binary output cycle setting x 0.5) This is the time that is required to capture data output (measured values/judgment results) on external devices.

Explanation of Operation

(1) Continuous measurement is started the moment that the mode changes to the RUN

mode.

(2) When measurement ends and the measurement processing time elapses, the

measured data is applied and output.

(3) Analog output is started after the measured data is applied and the analog output

response time (T3) elapses.

(4) Output is executed for the time specified as the binary output cycle after the IFU

binary output response time (T4) elapses and the measured data is applied.

(5) The GATE signal turns ON for the predetermined time and measured data is

captured on the external device after measured data is applied and the IFU binary output response time (T4) elapses.

The measurement cycle is 0.5 ms. Note, however, that the response time is 1 ms in the IC lead pitch and IC lead width judgment modes.

This is the time required until the measured data is applied. (max. 1 ms) Note, however, that the response time is 1.5 ms in the IC lead pitch and IC lead width judgment modes.

This is the time until the Controller starts analog output after completion of measurement. (100 µs)

T5: Binary output cycle

T6: GATE ON time

This is the time in which the Interface Unit outputs the binary data. This time can be changed. (1 to 500 ms (default value: 1 ms))

Explanation of Operation

(1) Continuous measurement is started the moment that the mode changes to the RUN

mode.

(2) When measurement ends and the measurement processing time elapses, the

measured data is applied and output.

(3) Analog output is started after the measured data is applied and the analog output

response time (T3) elapses.

(4) Output is executed for the time specified as the binary output cycle after the IFU

binary output response time (T4) elapses and the measured data is applied.

Important

The minimum binary output cycle is 1 ms. Because the measurement cycle in the high-speed mode (FAST) is 0.5 ms, binary output from the Interface Unit is executed once every two measurements.
