5 Measuring Principle Measuring principle of color sensors of SPECTRO-3 Series: The SPECTRO-3 provides highly flexible signal acquisition. For example, the sensor can be operated in alternating-light mode (AC mode), which makes the sensor insensitive to extraneous light. It also can be set to constant-light mode (DC mode), which makes the sensor extremely fast and allows a scan-frequency of more than 30KHz. If the integrated light source at the sensor is turned off and the sensor is set to DC mode, the sensor is able to detect so-called "self-luminous objects". With the stepless adjustment of the integrated light source and the selectable gain of the receiver signal the sensor can be set to almost any surface or any "self-luminous object". When the integrated light source of the SPECTRO-3 color sensor is activated, the sensor detects the radiation that is diffusely reflected from the object. As a light source the SPECTRO-3 color sensor uses a white-light LED with adjustable transmitter power. An integrated 3-fold receiver for the red, green, and blue content of the light that is reflected from the object, or the light that is emitted by a "self-luminous object", is used as a receiver. As mentioned above, a special feature here is that the gain of the receiver can be set in 8 steps. This makes it possible to optimally adjust the sensor to almost any surface and to different "selfluminous objects". The SPECTRO-3 color sensor can be "taught" up to 31 colors. For each of these taught colors it is possible to set tolerances. In X/Y INT or s/i M mode these tolerances form a color cylinder in space. In X/Y/INT or s/i/m mode the tolerances form a color sphere in space. Color evaluation according to s/i M is based on the lab calculation method. All modes can be used in combination with several operating modes such as "FIRST HIT" and "BEST HIT". Raw data are represented with 12 bit resolution. Color detection either operates continuously or is started through an external PLC trigger signal. The respective detected color either is provided as a binary code at the 5 digital outputs or can be sent directly to the outputs, if only up to 5 colors are to be detected. At the same time the detected color code is visualised by means of 5 LEDs at the housing of the SPECTRO-3. With a TEACH button at the sensor housing the color sensor can be taught up to 31 colors. For this purpose the corresponding evaluation mode must be set with the software. The TEACH button is connected in parallel to the input IN0 (green wire at cable cab-las8/sps). Parameters and measurement values can be exchanged between a PC and the SPECTRO-3 color sensor through the serial RS232 interface. All the parameters for color detection also can be saved to the non-volatile EEPROM of the SPECTRO-3 color sensor through this serial RS232 interface. When parameterisation is finished, the color sensor continues to operate with the current parameters in STAND-ALONE mode without a PC. The sensors of the SPECTRO-3 series can be calibrated (white-light balancing). Balancing can be performed to any white surface. A ColorCheckerTM table with 24 color fields is available as an alternative. Visualization Visualization of the color code: The color code is visualised by way of 5 yellow LEDs at the housing of the SPECTRO-3 color sensor. At the same time in the binary mode (OUT BINARY) the color code indicated on the LED display is output as 5-bit binary information at the digital outputs OUT0 to OUT4 of the 8-pin SPECTRO-3/PLC socket. The SPECTRO-3 color sensor is able to process a maximum of 31 colors (color code ) in accordance with the corresponding rows in the COLOR TEACH TABLE. An "error" respectively a "not detected color" is displayed by the lighting of all LED (OUT0... OUT4 digital outputs are set to HIGH-level). In the DIRECT mode (OUT DIRECT HI or OUT DIRECT LO) the maximum numbers of colors to be taught is 5 (color no. 0, 1, 2, 3, 4). If DIRECT HI is activated, the specially digital output is set to HI, while the other 4 are set to LO. If the current color does not correspond with any of the teach-in colors, all digital outputs are set to LOW (no LED is lighting). If DIRECT LO is activated, the specially digital output is set to LO, while the other 4 are set to HI. If the current color does not correspond with any of the teach-in colors, all digital outputs are set to HIGH (all LED are lighting). ( ) SPECTRO-3-FIO / Page 5 of 21

6 LED Display LED display: The color code is visualized by means of 5 yellow LEDs at the housing of the color sensor. At the same time the color code indicated at the LED display is output as 5-bit binary information at the digital outputs OUT0... OUT4 of the 8-pole PLC connector. In the DIRECT mode the maximum number of color codes to be taught is 5. These 5 color codes can be directly output at the 5 digital outputs. The respective detected color code is displayed by means of the 5 yellow LEDs at the color sensor housing OUT0 OUT1 OUT2 OUT3 OUT Error or not detected ( ) SPECTRO-3-FIO / Page 6 of 21

7 Parameterization Windows user interface: The color sensor is parameterized under Windows with the SPECTRO3-Scope software. The Windows user interface facilitates the teach-in process at the color sensor and supports the operator in the task of adjustment and commissioning of the color sensor. The RS232 interface (tab PARA1 or PARA2) is used for setting parameters such as: - MAXCOL-No.: Number of colors to be checked - POWER-MODE: Light power of the white-light LED - LED-MODE: Triggering of the internal light source - AVERAGE: Averaging over a maximum of values - TRIGGER: Continuous or external or self trigger - OUTMODE: Triggering of the digital outputs - COLOR GROUPS: Forming of color groups - INTLIM: Minimum intensity required for color evaluation - HOLD: Pulse lengthening up to 100ms max. Under Windows representation of the color value on a PC in numeric form and in a color chart, and representation of RGB values in a time chart. In addition the current RGB values are displayed as a bar chart. Explanation of general function groups and display elements: Tab CONNECT: Pressing the CONNECT tab opens a window for selecting and configuring the interface. IThe COMMUNICATION PROTOCOL function field is used for selecting either an RS232 or a TCP/IP protocol. If RS232 is selected, a port from 1 to 256 can be selected with SELECT COM PORT, depending on which port the sensor is connected to. If an adaptor is used, the COMPORT number can be determined by way of the hardware manager in the system control panel. If the sensor should communicate through a local area network, an RS232 to Ethernet adaptor will be needed. This adapter makes it possible to establish a connection to the sensor with the TCP/IP protocol. The network adaptors that are available from us are based on the Lantronix XPort module. For parameterising these adapters (assigning of an IP address, setting of the Baud rate of 19200) please download the "DeviceInstaller" software that is provided free of charge by Lantronix at DeviceInstaller is based on Microsoft's ".NET" framework. Detailed operating instructions for the "DeviceInstaller" software also are available from Lantronix. ( ) SPECTRO-3-FIO / Page 7 of 21

8 Parameterization Tab PARA1 Pressing the PARA1 tab opens a window for setting the sensor parameters.. EVALUATION MODE: This function field serves for setting the evaluation mode at the SPECTRO-3 color sensor. FIRST HIT: The currently measured color values are compared with the default values in the TEACH TABLE, starting with teach-color 0. If in the row-by-row comparison the current color values correspond with the teach-parameters entered in the TEACH TABLE, this first "hit" in the TEACH TABLE is displayed as a color number (C-No.) and is output at the digital outputs (OUT0... OUT4) according to the settings of the OUTMODE parameter (see OUTMODE). If the current color does not correspond with any of the teach-colors, the color code C-No. = 255 will be set ("error status"). BEST HIT: The currently measured color values are compared with the default values in the TEACH TABLE, starting with teach-color 0. If in the row-by-row comparison the current color values correspond with several of the teach parameters entered in the color table, the teach parameter that has the shortest x/y distance from the current color value will be a hit. This "hit" in the TEACH TABLE is displayed as a color number (C-No.) and is output at the digital outputs (OUT0... OUT4) according to the settings of the OUTMODE parameter (see OUTMODE). If the current color does not correspond with any of the teach-in colors, the color code C-No. = 255 will be set ("error status"). MIN DIST: The individual teach-in colors defined in the TEACH TABLE are present as points in the color triangle, defined by their (X,Y) value pairs. When this evaluation mode is set at the sensor, the evaluation algorithm, starting from the currently measured color value (X,Y), calculates the distance to the individual teach-in colors in the color triangle. The current color value (X,Y) is assigned to the teach-in color that is closest in the color triangle. It is furthermore checked whether the intensity condition for this color also is true. If the intensity condition is not true, the second shortest distance will be checked, etc. COL5: In this evaluation mode the rows 0 to 4 in the TEACH TABLE are evaluated. Every match of current vector (row number) and teach vector is directly sent to the corresponding output. ( ) SPECTRO-3-FIO / Page 8 of 21

9 Parameterization CALCULATION MODE: X/Y INT: The X/Y pairs of the individual red, green, and blue components, and the intensity are used for evaluation. For X/Y a color tolerance CTO can be set, and for the intensity an INT tolerance ITO can be set. With the individual tolerances the color is represented as a cylinder in space (see picture below). CTO defines the diameter of the cylinder, and ITO the height of the cylinder. s/i M: The s/i pairs of the individual red, green, and blue components, and M are calculated for evaluation. This calculation method follows the Lab calculation method. For s/i a color tolerance sito can be set, and for the intensity an M tolerance MTO can be set. With the individual tolerances the color is represented as a cylinder in space (see picture below). sito defines the diameter of the cylinder, and MTO the height of the cylinder. X/Y/INT: For evaluation, X, Y, and INT are calculated from the individual red, green, and blue components. These three values define a point in three-dimensional space. The tolerance value that is entered defines a sphere in space with radius TOL (see picture below). s/i/m: For evaluation, s, i, and M are calculated from the individual red, green, and blue components following the Lab calculation method. These three values define a point in three-dimensional space. The tolerance value that is entered defines a sphere in space with radius TOL (see picture below). INT, M CALCULATION MODE: X/Y/INT s/i/m TOL (sphere radius) P (X, Y, INT) P (s, i, M) Y, i X, s (0.5 x cylinder height) ITO MTO CTO (cylinder radius) sito CALCULATION MODE: X/Y INT s/i M ( ) SPECTRO-3-FIO / Page 9 of 21

10 Parameterization POWER MODE: In this function field the operating mode of automatic power correction at the transmitter unit (transmitter LED) can be set. STATIC: The transmitter power is constantly kept at the value set with the POWER [pm] slider (recommended operation mode). The POWER can be set with the slider or by entering a value in the editbox. A value of 1000 means full intensity at the transmitter unit, a value of 0 sets the lowest intensity at the transmitter. DYNAMIC: The LED transmitter power is dynamically controlled in accordance with the amount of radiation that is diffusely reflected from the object. By using the intensities measured at the receivers the automatic control circuit attempts to adjust the transmitter power in such a way that the dynamic range, which is determined by DYN WIN LO and DYN WIN HI, is not exceeded. LED MODE: This item serves for setting the control mode for the integrated light source of the sensor. DC: In this mode the sensor operates extremely fast and reaches a scan frequency of more than 30KHz. Unfortunately the sensor is somewhat sensitive to extraneous light in DC mode, but if the extraneous light source does not directly shine into the sensor's receiver, the signal only is influenced to a very small extent. AC: In this mode the sensor is insensitive to extraneous light, which is achieved by "modulating" the integrated light source, i.e. by turning the light on and off. The extraneous content in the signal is determined in off status and is simply subtracted from the on status.. PULSE: In pulse mode the transmitter unit is pulsed, which for a very short time directs a high light intensity onto the object. Afterwards the transmitter unit must be turned off for a longer time, which compared to the AC mode reduces the scan frequency approximately by a factor of 5. OFF: The sensor's internal light source is turned off in DC mode by POWER [pm] = 0, the sensor can be used for so-called "self-luminous objects". Self-luminous objects are light sources that actively emit light (LEDs, lamps, etc.). In OFF mode the POWER MODE and POWER cannot be adjusted, and external teaching with DYN1 is not possible. AVERAGE: This function field is used for adjusting the number of scanning values (measurement values) over which the raw signal measured at the receiver is averaged. A higher AVERAGE default value reduces noise of the raw signals at the receiver unit and there will be a decrease of the maximal available switching frequency of the sensor. MAXCOL-No.: This function field serves for setting the number of colors to be checked. In the BINARY mode the maximum number of colors to be checked is 31. In the DIRECT HI or DIRECT LO mode the maximum number of colors to be checked is 5 (colors no. 0, 1, 2, 3, 4). The numerical value set here determines the currently possible scanning rate of the color sensor. The less the colors to be checked, the faster the operation of the sensor. The numerical value set here refers to the number of rows (starting with row 0) in the TEACH TABLE.. OUTMODE: This group of buttons offers the method of how to control the 5 digital outputs. BINARY: If in this row-by-row comparison the current color values correspond with the teach-in parameters entered in the TEACH TABLE, this color in the TEACH TABLE is displayed as a color number (C-No.) and is sent to the digital outputs (OUT0... OUT4) as a bit pattern. The maximum number of colors to be taught is 31. DIRECT: In this mode the maximum number of colors to be taught is 5. If in this row-by-row comparison the current color values correspond with the teach-in parameters entered in the TEACH TABLE, this color in the TEACH TABLE is displayed as a color number (C-No.) and is sent direct to the digital outputs (OUT0... OUT4). DIRECT HI: If DIRECT HI is activated, the specially digital output is set to HI. If the current color does not correspond with any of the teach-in colors, all digital outputs are set to LOW (no LED is lighting) DIRECT LO: If DIRECT LO is activated, the specially digital output is set to LO, while the other ones are set to HI. If the current color does not correspond with any of the teach-in colors, all digital outputs are set to HIGH (all LEDs are lighting). INTLIM: This edit box is used for setting an intensity limit. Color evaluation is stopped, if the current intensity INT arriving at the receiver unit falls below this limit, and ERROR STATE is output. ( ) SPECTRO-3-FIO / Page 10 of 21

11 Parameterization TRIGGER: This function field serves for setting the trigger mode at the sensor. If TRIGGER is not CONT, the TRIG LED shows a trigger event. CONT: Continuous color detection (no trigger event required). SELF: By selecting SELF the sensor can be operated in self-trigger mode. The "free status" must be taught to row 0. With a split optical fibre in transmitted-light operation the free status, for example, is the uncovered status. In reflected-light operation the free status is the status when there is no part. Color detection is started when row 0 is no longer detected (self-trigger). After the trigger, i.e. when color 0 is detected again, the color from the taught colors will be output that was detected most frequently during triggering. EXT1: Color detection is started through the external trigger input (IN0 pin3 green of cable cab-las8/sps) or by means of a click on the TEACH button. A trigger event is recognized as long as +24V is present at the IN0 input (HIGH-active). After the trigger input goes to LOW again, the state (color no.) that was last detected will be held at the outputs. EXT2: Same behaviour as in EXT1 mode, with the difference that an error state (color no. = 255) will be output after the trigger input goes to LOW again. EXT3: Color detection is started through the external trigger input (IN0 Pin3 grn at cable cab-las8/sps) or by pressing the TEACH button. After triggering the color from the taught colors will be output that was detected most frequently during triggering. EXT4: Same behaviour as in EXT1. However, in contrast to EXT1 in this mode the transmitter source will be switched off if no trigger event (IN0 or TEACH button) is given. EXTTEACH: In all the evaluation modes teaching of a color can be performed externally through IN0 or by means of the button at the sensor housing. OFF: The external TEACH feature is deactivated. ON : See below. STAT1: In static power mode, a color is taught to position 0 in the TEACH TABLE. The POWER MODE is automatically set to STATIC. A fixed transmitter poser must be set with the POWER slider. When the button at the sensor housing is pressed, or after a positive signal (+24V) at input IN0, the current color is taught to row 0. DYN1: In dynamic power mode, a color is taught to position 0 in the TEACH TABLE, and evaluation is then performed statically. The POWER MODE is automatically set to STATIC. When the button at the sensor housing is pressed, or after a positive signal (+24V) at input IN0, the transmitter power is set such that the sensor is in the dynamic range, which is defined by DYN WIN LO and DYN WIN HI. The current color is then taught to position 0 in the TEACH TABLE. The sensor then continues to operate statically with the established POWER value. The taught color is stored only in the RAM and not in the EEPROM of the sensor. ( ) SPECTRO-3-FIO / Page 11 of 21

12 Parameterization Tab PARA2: A click on PARA2 opens a view where colors in the TEACH TABLE can be assigned to certain groups, and for each color and the error status an explicit HOLD time can be set. COLOR GROUPS: It is possible to form color groups in evaluation modes FIRST HIT, BEST HIT, and MIN DIST. This means that in a special table the individual rows are assigned to a group. HOLD in [ms]: The sensor operates with minimum scanning times in the magnitude of less than 100μs. This is why most of the PLCs that are connected to the digital outputs have difficulties with the safe detection of the resulting short switching state changes. Entering values in the table provides pulse lengthening at the digital outputs of the sensor system up to 100 ms. Each individual row can be assigned its own HOLD time. Tab TEACH TABLE: A click on the TEACH TABLE tab opens a view where colors can be taught to the TEACH TABLE. The TEACH TABLE is organized in rows, i.e. the individual parameters for the teach-in colors are arranged side by side in the respective row. The sensor is able to check up to 31 teach-in colors. The number of the respective teach-in color is given in the left column of the table. Only the green rows are used for evaluation in the sensor. The number of rows to be inspected is set with MAXCOL-No. ( ) SPECTRO-3-FIO / Page 12 of 21

13 Parameterization Tab TABLE ATTRIBUTES: A click on TABLE ATTRIBUTES opens a panel where the row color in which the individual tolerance circuits are represented can be individually chosen or these can be automatically replaced by the color detected by the system. Furthermore, designations for the individual rows can be entered in the SPECIFICATION table. These designations are saved on the PC's hard disk and can be loaded again, if necessary Tab RECORDER: The SPECTRO3-Scope software features a data recorder that allows the saving of RED, GREEN, BLUE, X, Y, INT, C-No: and TEMP. The recorded file is saved to the hard disk of the PC and can then be evaluated with a spreadsheet program. The file that is created has eight columns and as many rows as data frames were recorded. A row is structured as follows: Date and time, RED, GREEN, BLUE, X, Y, INT, C-No:, TEMP. Tab CALIBRATE: White light balancing can be performed with the sensors of the SPECTRO-3 series. Balancing can be performed to any white surface. A ColorCheckerTM table with 24 color fields according to CIE standard is available as an alternative, and white light balancing or calibration can then be performed to one of the white fields.

14 Parameterization Graphic display elements: SOURCE: A click on the arrow button opens a selection field for the selection of a display mode in the graphic display window. X/Y INT or s/i M: X/Y or s/i pairs are displayed in a zoomed graph. The intensity INT or M with the tolerance window set under No.: is shown directly below. Two-side view of the color cylinder in space. X/Y/INT or s/i/m: A panel opens that shows the taught color spheres and the current color position. For improved representation a three-side view with the graphs X/Y (s/i), X/INT (s/m) and Y/INT (i/m) was chosen. This display shows the temperature prevailing in the sensor housing. The display DOES NOT show degrees Centigrade or Fahrenheit. Operation of the TEMPCOMP-Scope software: If a firmware update should go wrong and the temperature characteristics that are stored in the EEPROM should be lost, these characteristics must be created anew. For this purpose you will need a file with the corresponding data. This file can be obtained from your supplier. To perform temperature compensation please start the corresponding TEMPCOMP-Scope software that is included on the supplied CD. Please make sure that you have a functioning sensor connection. It may be necessary to select the connection with CONNECT. Set the correct sensor under SELECT SENSOR, if this is not done automatically. ( ) SPECTRO-3-FIO / Page 14 of 21

15 Fiber Optics Field of use: Optical fibers offer solutions for difficult tasks in optoelectronis. They can be used universally and allow flexible applications. Advantages: - Highest quality - Selection from different fiber types - Thermal stability - Great variety of available standard sensor heads - Special designs - Various attachment optics available Characteristics: Light-conducting glass fibers are optical components that allow the transmission of light through any curved path based on the principle of total reflection. The individual fiber is composed of high-break core glass and low-break cladding glass. The light beams entering the core glass within the critical angle are guided through the fiber by way of reflection at the core/cladding contact surfaces (step index fiber). The highly flexible optical fibers are made of bundled individual glass fibers. The ends are each glued into a sensor head and a connector. The faces are optically polished. For protection against mechanical, chemical, or thermal destruction the optical fibers are provided with a corresponding protective sheath.

21 Application Example Color checking of LED lamps Differently colored LED lamps should be detected. On the one hand the active color, caused by the LEDs in the lamps, should be checked, and on the other hand the passive color, here the colored or transparent plastic. The test was performed with a SPECTRO-3-FIO in combination with a R-S-A2.0-(2.5) optical fibre, because this series allows both the detection of passive and of active colors. Measurement was performed in DC operating mode, in BEST HIT mode with x/y INT setting.
