5 CTROLLERS The controller is easy to operate with simple pushbutton setup and an LCD display to verify / change the settings. 3 LCD Display The A-N(or P) controller has a built-in color display that indicates multiple data values on the same screen. Distance values from both heads, calculated value, output status, bank number, etc. are displayed on the normal run screen. Light intensity monitor For L-25 only For stable measurement and improved accuracy the light intensity needs to be adjusted to the optimum setting. With the built-in monitor the status of the level can be verified. Red line on measuring point Threshold of receiving light intensity Further from head Closer to head Blue wave means reflection from the object. Convenient to find the peak reflection. Ten formulas of calculation A B A+B A-B -A-B K-A-B K+A+B K+A-B K+A K+B Sensor head A Sensor head B Adding of A and B Gap between A and B Reverse of A+B K = distance between sensors. Good for measuring thickness. K = Offset value K = Offset value Offset the sensor A. K = Offset value Offset the sensor B. K = Offset value Electronic shutter The microcomputer in the controller will automatically control the shutter speed depending upon the reflectance of the target. This will select the best light intensity level for accurate measurement and will help to minimize the error (AUTO Sensitivity Mode). Saturation level 8 Banks selections Bank No. Bank 2 input Bank 1 input Bank input Sensing element Highly reflective materials will result in excessive reflected light that may cause an error in finding the peak position. Sensing element Sensing element Low reflective materials such as black rubber will have a very low amount of reflected light. This can cause unstable measurement. Automatic control of light intensity will find the peak correctly. Saturation level 283

6 3 RS-232C Communications By connecting the controller to a PC, the following operations can be performed from the PC via RS232. Writing and reading out the setting value Reading out the measurement value Reading out the control output status Operating the control input Data buffer function Communication method Transmission type Baud rate Transmission code Data length Stop bit length Parity check Data classification RS-232C Asynchronous 96/192/384/1152 bps ASCII 7/8 bit 1 bit Nil/Ever number/odd number STX ETX The underlined values are the factory default settings. Adjust the communication settings of the PC and the using the values in the above table. The settings of the controller can be accessed in screen number 14 (RS232C). Low / High pass filters High / Low pass filters are built into the controller. A low pass filter will help to reduce any sudden changes in the measurement while the high pass filter will eliminate slow gradual changes. Easy disconnection of QD type. 5 Independent outputs are available This is convenient for sorting items according to size. Each of the 5 comparator outputs can be set independently, all outputs have a high and low threshold limit. Output 5 E Two sensing heads can be controlled Therefore it computes for the purpose of measuring thickness, width, etc. Independent measurement from each head is possible as well. Any combination of measurement heads (3, 85, 35) can be used together. Output 4 D Output 3 C Output 2 B Output 1 A 284
