Introduction Introduction
Introduction
Thank you for purchasing the ZX-L-N Series Smart Sensor. This manual provides information regarding functions, performance and operating methods that are required for using the sensor. When using the ZX-L-N Smart Sensor, make sure to observe the following: · The ZX-L-N Smart Sensor must be operated by personnel knowledgeable in electrical engineering. · To ensure correct use, please read this manual thoroughly to deepen your understanding of the product. [. . . ] Automatic teaching is useful when you want to set threshold values by starting the device and obtaining real measurements.
Position teaching
Two-point teaching
Automatic teaching
Hysteresis (hysteresis width) can also be set for threshold values. Set hysteresis when judgements are unstable to prevent chattering.

Section 5 DETAILED SETTINGS
Inputting Threshold Values Directly
The threshold values can be set by directly inputting the numeric values. Direct input is useful when you know the dimensions for an OK judgement or when you want to fine-tune threshold values after teaching.
Moving to T Mode
1. Set the mode switch to T.
RUN T FUN
Setting Threshold Values
2. Move the threshold switch to either H or L,
i. e. , the threshold to be set.
The current measured value will be displayed on the main display. The currently set threshold value (either HIGH or LOW, depending on the threshold switch setting) will be displayed on the sub-display.

3. Press any Cursor Key.
The leftmost digit of the sub-display will flash.

4. Use
the Cursor Keys to set the threshold
Moves from one digit to another. Press the ENT Key to confirm the setting.
The setting will be registered.

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.
Sensor head Sensor head
Threshold sample (Upper limit)
Teaching point = LOW threshold
Threshold sample (Lower limit)
Teaching point = HIGH threshold
Hold, trigger mode, and scaling settings that have been made before teaching are reflected in the teaching measurements.

3. Place the threshold sample in position.
The main display value changes.
4. Press the ENT Key for at least one second
and then release.
The measured value at the point that the ENT Key is released will be set as the threshold value. This threshold value will be shown on the sub-display.

When [ERRLH] or [ERRHL] is displayed p. 89
The threshold values set using position teaching can be changed using direct input. This is useful when setting judgement tolerances for measured values.

Two-point teaching
Performs measurement on two samples and uses the intermediate value of the two measurement results to set threshold values. Two-point teaching is useful when you want to detect subtle differences between the standard sample and defective samples.
Sensor head Sensor head
Teaching point A Standard sample Defective sample Teaching point B
The threshold can be calculated by the following equation. Threshold = (Teaching point A + Teaching point B) / 2 Section 5 Entering Threshold Values

Direct intrabeam viewing of Class 3A lasers with optical aides (e. g. , binoculars, telescopes, microscopes) may be hazardous. Lasers which are also capable of producing hazardous diffuse reflections. Their use requires extreme caution.

Class 3B Class 4
Note: Conditions for safe viewing of diffuse reflections for Class 3B visible lasers are: minimum viewing distance of 13 cm between screen and cornea and a maximum viewing time of 10 s. [. . . ]
