Precautions for Safe Use

Always observe the following precautions to ensure safety.

■ Environment

• Do not use the Smart Sensor in locations subject to explosive or flammable gases.

• To ensure safety in operation and maintenance, do not install the Smart Sensor near high-voltage equipment or power devices.

■ Power Supply and Wiring

• Do not impose voltages exceeding the rated voltage (12 to 24 VDC ±10%).

• When supplying power to the Sensor, make sure that the polarity of the power is correct, and do not connect to an AC power supply.

• Do not short-circuit the load for the open collector output.

• Do not lay the power supply cable for the Smart Sensor together with high-voltage lines or power lines. Doing so, or placing them into the same duct, can cause induction and lead to malfunction or damage.

• Always turn OFF the power supply before wiring and before connecting or disconnecting connectors.

PREFACE

Preface Precautions for Safe Use

■ Settings

• When setting the threshold value with the Smart Sensor connected to an external device, turn ON the Amplifier Unit's judgement output hold input to prevent the judgement from being output to the external device.

■ Others

• The ZX-L-series Smart Sensors (Laser Type), ZX-W-series Smart Sensors (Microwave Type), and ZX-T-series Smart Sensors (High-precision Contact Type) are not compatible. Do not use ZX-L-series, ZX-W-series, or ZX-T-series Smart Sensors together with ZX-E-series Smart Sensors.

• Do not attempt to disassemble, repair, or modify the Smart Sensor.

• When disposing of the Smart Sensor, treat it as industrial waste.

PREFACE

Preface Precautions for Correct Use

Precautions for Correct Use

Always observe the following precautions to prevent operation failures, malfunctions, and adverse effects on performance and equipment.

Smart Sensor Installation

■ Environment

Do not install the Smart Sensor in the following locations:

• Locations where the ambient temperature exceeds the rated temperature range

• Locations subject to rapid changes in temperature (causing condensation)

• Locations where the relative humidity exceeds the range of 35% to 85%

• Locations subject to corrosive or flammable gases

• Locations where dust, salt, or metallic powder accumulate on the Sensor

• Locations subject to direct vibration or impact

• Locations subject to direct sunlight

• Locations subject to exposure to water, oil, chemicals, etc.

• Locations subject to strong electromagnetic or electrical fields

• Locations subject to water vapor

Installation and Handling of Components

■ Power Supply and Wiring

• Do not extend the Sensor Head cable by more than 8 m. Use a ZX-XC@A Extension Cable (order separately) to extend the cable from the Sensor.

• Use a shielded cable to extend the Amplifier cable. The shielded cable must have the same specifications as that of the Amplifier cable.

• When using a commercially available switching regulator, ground the FG (frame ground) terminal.

• If the power supply line is subject to surges, connect a surge absorber that meets the conditions of the application environment.

• When connecting multiple Amplifier Units, connect the linear grounds of all the Amplifier Units.

■ Warm-up

After turning ON the power, allow the Smart Sensor to warm up for 30 minutes minimum prior to use. The circuitry is not stable immediately after turning the power ON, and the values gradually change until the Sensor is completely warmed up.

■ Maintenance and Inspection

• Always turn OFF the power supply before adjusting or removing the Sensor Head.

• Do not use thinners, benzine, acetone, or kerosene to clean the Sensor Head or Amplifier Unit.

• Use a different ground for the linear output from the normal ground.

• Always ground the linear output terminal even when linear output is not used.

(8) When the judgement output hold input is turned ON, the judgement outputs are held and not

output to the external devices. Turn the judgement output hold input ON when setting threshold values.

When setting threshold values while connected to external devices, turn ON the Amplifier Unit’s judgement output hold input to prevent the outputs to external devices from changing.

(9) The zero reset input is used to execute and clear zero reset.

(10) The timing input is for signal input from external devices. Use it for hold function timing.

Confirming Warm-up Completion

When the power is turned ON in RUN or T Mode, the sub-display will flash W-UP to show that the Sensor is warming up. Warm-up requires approximately 5 to 15 minutes. When warming up has been completed, the normal display will be shown.

Measurement operations can be performed while in warm-up display status, but the precision of measurements before warming up has been completed will be low. For high-precision measurements, wait until warming up has been completed.

The number of samples to average is the number of data points used to average data measured by the Sensor. The average value will be output.

Use the number of samples to average function to ignore sudden variations in measured values. If the number of samples is increased, however, the response time of the judgement outputs and linear output will be increased.

Setting Delay Time

Delay time is set to ignore measurements immediately after the timing input. This is useful for avoiding bounding during device startup and the influence of machine vibration.

The default delay time setting is OFF.

Make the sum of the delay time and sampling period less than the timing input ON interval. If the next timing input for measurement is received before the delay and sampling period have passed, that timing input will be ignored and will not be reflected in the sampling.

Comparing Measured Values (Previous Value Comparisons)

Use the previous value comparison function to ignore gradual changes in measured values over time, due to factors such as temperature drift, and only detect and judge sudden changes.

The hold function must be set before previous value comparison can be set. The difference from the previous hold value with a PASS judgement becomes the measured value. For example, if the judgement for that previous measurement is HIGH or LOW, the comparison is performed with the hold value before that.

Direct input is useful when you know the dimensions for an OK judgement or when you want to fine-tune threshold values after teaching.

Position teaching Performs measurement and uses the measurement results to set threshold values.

Position teaching is useful when threshold samples, i.e., with the upper and lower limits, can be obtained beforehand.

Automatic teaching Performs measurement continuously while the keys are held down and sets the
