When using the ZS-L Smart Sensor, be sure to observe the following: · The ZS-L 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. · Please keep this manual in a safe place so that it can be referred to whenever necessary. How to Switch the Display Language to English Turn the power ON with the MENU key held down. [. . . ] value) AVERAGE Holds the average measured value during the sampling period. The output changes at the end of the sampling period and is held until the end of the next sampling period. Output (average) Sampling period Current measured value 3-24 ZS-L User's Manual Section 3 Setting Output Processing of Sensing Information Setting SAMPLE Description Holds the measured value at the start of the sampling period. The output changes at the start of the sampling period and is held until the start of the next sampling period. Output Current measured value Sampling period Section 3 SETUP Triggers Set the input method for the timing of the start and end of the measurement period. FUN Mode-[OUTPUT]-[HOLD]-[TRIGGER] Setting EXT Description Enters the trigger for the start of sampling by using the timing input. (default value) Timing input ON OFF Sampling period When a delay time is set, the input OFF timing and the end of the sampling period will not be synchronous. SELF-UP The sampling period is the period that the measured value is greater than the specified self-trigger level. Hold measurement is possible without a sync input. Self-trigger level Measured value Sampling period Sampling period Hysteresis width (for self-trigger) Action point Return point When SELF-UP is selected, the following items are subsequently displayed: · TRG LEVEL Sets the desired self-trigger level. Range: -999. 99 to 999. 999 · TRG HYS Sets the hysteresis width for the self-trigger. Range: 0 to 999. 999 When a delay time is set, the timing when the measured value becomes smaller than the self-trigger level and the end of the sampling period will not be synchronous. Sampling will end after the specified sampling period has elapsed. User's Manual ZS-L 3-25 Section 3 Setting Output Processing of Sensing Information Setting SELF-DN Description The sampling period is the period that the measured value is smaller than the specified self-trigger level. Measured value Self-trigger level Hysteresis width (for self-trigger) Sampling period Action point Return point When SELF-DOWN is selected, the following items are subsequently displayed: · TRG LEVEL Sets the desired self-trigger level. Range: -999. 99 to 999. 999 · TRG HYS Sets the hysteresis width for the self-trigger. Range: 0 to 999. 999 When a delay time is set, the timing when the measured value becomes greater than the self-trigger level and the end of the sampling period will not be synchronous. Sampling will end after the specified sampling period has elapsed. Section 3 SETUP chattering. Set the hysteresis width based on the fluctuations in the measured values around the trigger level. The hysteresis will be applied from the start of the sampling period and will prevent timing input 3-26 ZS-L User's Manual Section 3 Setting Output Processing of Sensing Information DELAY A delay time is set to ignore measured values immediately after the timing input. This is useful for avoiding bounding during device startup and the influence of machine vibration. The delay time (the delay between timing input and the start of sampling) and the sampling period can be set. Delay time ON OFF Sampling period Delay time Timing input Section 3 SETUP Ignored Accepted FUN Mode-[OUTPUT]-[HOLD]-[DELAY] Setting OFF ON Description The delay time is not set. When ON is selected, the following items are subsequently displayed: · T-DELAY Sets the delay time. Range: 1 to 5000 (ms) Set so that the "delay time + sampling time" is less than the timing input ON interval. If the next timing input for measurement is received before the "delay time + sampling period" has elapsed, that timing input will be ignored and will not be reflected in the sampling. User's Manual ZS-L 3-27 Section 3 Setting Output Processing of Sensing Information Setting Zero Reset When the zero reset function is used, the reference value "0" is registered as the height and the measured value can be displayed and output as a positive or negative deviation (tolerance) from the reference value. In the RUN mode, the measured value can be reset to 0 at any timing during measurement. Example 1: Using the height of sensing object registered as the reference value and the tolerance output as the measured value Sensor Head Section 3 SETUP -2 (LOW threshold value) 0 (reference value) Sensing object +2 (HIGH threshold value) Example 2: Using the height of sensing object as the measured value with an offset set to 10 Sensor Head +8 (LOW threshold value) 10 Sensing object +12 (HIGH threshold value) Example 3: Using zero reset to measure steps in sensing object (zero reset at each measurement) Sensor Head This step is measured. Zero reset executed Zero reset executed Zero reset executed Direction of movement To execute a zero reset: Press the SET key in the RUN mode. [. . . ] ANSI description A Class 1 laser is considered to be incapable of producing damaging radiation levels during operation and maintenance and is, therefore, exempt from any control measures or other forms of surveillance. Section 6 APPENDIX Class IIa/2a Class II/2 Class 2 lasers are divided into two subclasses, 2 and 2a. A Class 2 laser emits in the visible portion of the spectrum (0. 4 to 0. 7 µm) and eye protection is normally afforded Limits applicable to products that have emis- by the aversion response including the blink reflex. sions in the visible spectrum (400 to 710 nm) for emission durations in excess of 0. 25 second, providing that emissions for other durations and/or wavelengths do not exceed the Class I limits. Class II products are considered hazardous for direct long-term ocular exposure. User's Manual ZS-L 6-31 Section 6 APPENDIX Class Class IIIa/3a FDA definition Limits to products that have emissions in the visible spectrum and that have beams where the total collectable radiant power does not exceed 5 milliwatts.
