3 / 35 page  Patent Pending Large, Easy-to-Read Displays: Clear Even from a Distance Incident level Threshold level Function Setting Industry's largest characters: 6 mm (like earlier models) Function numbers added to function items. Settings are now reversible. Seven Convenient Display Formats An incident level/threshold display, percentage/threshold display, and large bar graph display have been added, so you can select the best display method for the application. Display the peak level when light was brightest and bottom level when light was dimmest. The digital levels of high-speed objects can be read precisely. (Refreshing the hold level was changed from a fixed time to synchronizing with the output, so the peak and bottom hold values can be checked with certainty.) Threshold level Patent Pending Without workpiece With workpiece Transparent workpiece Incident level does not change. Incident level changes. Detection is not possible Incident level Threshold level Incident level Threshold level Bar display 4 5 Industry's First Power Tuning Function in a Digital Sensor. Settings can be made more simply and confident- ly with two digital displays. For example, the threshold value can be changed while reading the incident level or a setting can be changed while confirming the setting's function item number. The displays are large and easy-to-read, despite the small case. High-speed mode Short-distance mode Standard mode Long-distance mode Super-long-distance mode The best mode for each application was selected from several power modes. The Sensor can be used immediately without setting the mode. If the incident light level is too high or too low, just press the Mode key to achieve the optimum status. Change the threshold level while read- ing the incident level. Verify the difference between the inci- dent level and threshold level while set- ting the threshold level. Check the incident level intuitively. Ideal when it is better to view an analog dis- play instead of the actual digital level. Incident level Peak hold Simultaneously display the peak hold level and present incident level. The optical axis can be adjusted more easily and surely by checking the peak hold level while adjusting the optical axis. Incident Level/Threshold Display Percentage/Threshold Display Large Bar Graph Display Detecting missing tablets RUN mode SET mode Incident Level/Peak Hold Display Peak Hold/Bottom Hold Display 1350 1280 2010 2055 Incident level Threshold level Press Press Earlier Method New Method Earlier Method New Method Large, bright operation indicator (like earlier models) Power tuning indicator added to indicate setting status. No power modes Up to 1/25 reduction Up to 5-fold increase Detection is possible. Press No incident light Incident light No complicated mode settings. Troublesome power adjustments have been eliminated, so it isn't necessary to select from power mode settings, such as long-distance mode, standard mode, and short-distance mode. When the MODE Key is pressed once, the power tuning function shifts the power level so that the present incident level is set to the ideal level (2000 on the digital display.) Insufficient light or saturation at short distances can be corrected. The power tuning range is extended to the allowable limits to eliminate prob- lems such as insufficient light or detection failures due to saturation. If the installation distance is too short, the incident light may saturate (i.e., to a digital incident level of 4,000), preventing detection. The power can be tuned down to 1/25th of the default setting for stable detection even at close range. Variations between different Sensors can be eliminated. Threshold levels had to be set and maintained separately for individual Sen- sors due to variations in the digital light levels measured by each Sensor. With power tuning, the incident level can be fine-tuned so the same thresh- old level can be set for each Sensor in an application. Maintenance is also simplified because it is easier to recognize measurement levels that have shifted during operation. Appropriate Appropriate Saturated Saturated Incident insufficient Digital light levels vary due to individual differences in the Sensors, so the threshold levels must be set individually. All of the Amplifiers are set to the same digi- tal light level, so the same threshold level can be set and maintained for the Sensors. |
