12 1 Overview 1.3 Features of CSD Basic functions The CSD-709 supports the following basic functions. The CSD-709 captures the sharp peak load more accurately by means of high-speed AD sampling of up to times/s, an analog low-pass filter, a digital low-pass filter, and moving-average processing. It also supports an analog peak hold function that enables more rapid peak capturing regardless of sampling rate. The CSD-709 supports a simplified calibration function that starts the calibration process by simply holding down a key. Calibration based on communication through various interfaces is also available. In the pre-work check, you can use preset check values to easily verify that the correct calibration status is maintained. The load currently applied to the strain-gage-based transducer, such as the load cell, is displayed in mv/v, allowing you to separate abnormal values and unstable measured values. Tracks and peaks can be output in analog form. The hold target can be flexibly selected from displayed values and comparative outputs. Up to four different types of calibration data or comparator settings are memorized so that you can select the desired value by means of key operation or external control input. You can select the peak detection mode from 36 modes configured through a combination of nine hold modes (peak hold, bottom hold, peak-bottom hold, peak-to-peak hold, maximum hold, minimum hold, maximum-minimum difference hold, average hold, and four inflection point holds) and four section modes (entire section, specified section, time-specified section, and automatic start time-specified section) Addition of functions using options The following additional functions become available through mounting options.

15 1 Overview 1.5 Mode The CSD-709 supports the following measurement and operating modes. Measurement mode Function mode C function mode P function mode CAL selection mode CCAL mode CADJ mode VCAL mode VADJ mode Check mode COMP setting mode Measurement mode: You can display the value currently measured. Measurement mode is further divided into two modes: Track mode and Peak mode. In Track mode, the value, which is input from the measuring unit and changes with the elapse of time, is displayed in the load window. In Peak mode, the maximum and minimum measurements are detected and held. Function mode: You can set the functions prefixed with [F-], including the function related to the number of AD sampling times and the measurement of the digital filter, the function related to comparisons (e.g., operation of the comparator), and the function related to the operation of the key lock and hold target, and check these settings. C function mode: You can set the functions prefixed with [CF-], including the selection of calibration number, decimal point display position, and current calibration data, and check these settings. P function mode: You can set the peak hold related functions prefixed with [PF-], including determination of the detecting section and execution of detection, and check these settings. CAL selection mode: You can select CCAL mode used for calibration, CADJ mode used for fine adjustment of calibration results, and VCAL mode and VADJ mode used for calibration and adjustment of optional current output and voltage output cards. Check mode: You can check CSD-709's ROM version, mounted options, external control operations, and the like. COMP setting mode: You can set comparison values and check comparator settings. 13

16 1 Overview The mode in which multiple detection operations, such as peak detection, maximum detection, and inflection point detection, are combined to obtain the results from the load changing with the elapse of time is called [multimode] and distinguished from operations based on a single detecting sequence ([single mode]). 14

17 1 Overview 1.6 Basic key operation To toggle between Measurement mode and any other mode, use the key. To move to any of COMP setting modes from the Function mode, press the or key to change the display, then press the key.

22 2 Installation and Wiring 2.2 Wiring WARNING Turn off power before connecting or disconnecting cables. The CSD-709 is not equipped with a power switch. When you conduct work with the CSD-709 turned on, electric shock or equipment damage may result. Before turning on power, check to confirm that the power supply voltage indicated on the CSD-709 and in the specifications agrees with the voltage actually supplied. Using an unconfirmed power supply may result in electric shock or equipment damage. CAUTION The connector board on the rear panel of the CSD-709 is a resin component. Do not drop it or subject it to strong impact. Always use shielded cables, except for power cables. Separate cables from noise sources, including power cables of peripheral devices and control I/O. In the conduit, arrange cables only for the CSD-709. Avoid joint use with other lines in the conduit. Ground the CSD-709 based on Type D single grounding using a protective ground connector. Also, do not use the grounding line of the CSD-709 to ground the power supply system. 20

23 2 Installation and Wiring Plugging in the strain-gage-based transducer connector The strain-gage-based transducer connector is used to connect signal cables of the strain-gage-based transducer, such as load cell or pressure sensor, to the CSD-709. Also, this connector is used to connect monitor output signal cables. Shown below are terminal locations on the strain-gage-based transducer connector. Terminal symbol Terminal Color code of signal cable A Strain-gage-based transducer connector (+EXC) Red B Strain-gage-based transducer connector (-SIG) Blue C Strain-gage-based transducer connector (-EXC) White D Strain-gage-based transducer connector (+SIG) Green E Strain-gage-based transducer connector (shield) Yellow + Monitor output (+) - Monitor output (-) For example, one load cell is connected to the CSD-709 as shown below. 21

24 2 Installation and Wiring Similar to the connection with one load cell, one load cell and one junction box (B-304) are connected to the equipment as shown below. Junction box This time, connect signal cables as shown below in the extended junction box. To load cell Red Blue White Green Yellow (shield) Conforming crimp terminal: or 2-4 Terminal pitch: 9.5 mm Red Blue White Green Yellow (shield) To CSD-709 CAUTION The signal cable colors shown above are our standard color codes. Each transducer manufacturer employs unique signal colors for strain-gage-based instruction manual and inspection result record of the strain-gage-based transducer to be used before transducers such as the load cell. For this reason, check the connecting signal cables to the CSD-709. When you intend to use a tensionn type or compression and tension type load cell and define the direction of tensionn as a positive direction, swap the signal cables of +SIG and -SIG beforee connection. Arrange the CAB-502 cable between junction box and CSD-709 so that the length of the cable will not exceed 30 m. If the length exceeds 30 m, the input voltage to the CSD-70warranted measurement accuracy. will drop due to cable resistance, creating a risk of deviations from 22

25 2 Installation and Wiring With respect to the excitation voltage to the strain-gage-based, you can select a voltage level from 2.5 VDC, 5 VDC, and 10 VDC. The selected excitation voltage determines the number of parallelly connectable strain-gage-based transducers as shown below. Excitation voltage Number of parallelly connectable transducers 2.5 VDC 8 5 VDC 4 10 VDC 2 For excitation voltage setting procedures, see Section 2.3, "Setting the excitation voltage". Described below are procedures used to plug in signal cables to the strain-gage-based transducer connector of the CSD Remove the sheath at the end of each signal cable by 6 mm to 7 mm. 2. Insert the signal cable into the hole of the strain-gage-based transducer connector (A) and tighten the screw at the top face of the connector. CAUTION In case of stranded cable, lightly twist core wires so that they will not be separated. If core wires are twisted excessively, the cable may be easily disengaged from the connector. 3. Mount the strain-gage-based transducer connector to the CSD-709 and tighten the two screws (A) at the ends of the connector. A A 23

26 2 Installation and Wiring Plugging in the monitor outpu Voltages proportional to the inputs from the strain-gage-based of monitor output. The monitor output can be used transducer, such as the load cell or pressure sensor, can be picked up in the form when you want to observe or record waveforms with a recorder. The monitor output will take any of the values shown below depending on the excitation voltage input to the strain-gage-based transducer. (Note that the monitor output is a voltage per 1 mv/v of input signal.) Excitation voltage Monitor output 2.5 VDC Approx. 0.5 V 5 VDC Approx. 1 V 10 VDC Approx. 2 V CAUTION The monitor output voltage is picked up beforee the input signal from the strain-gage-based transducer is AD-converted. Therefore, the monitor output does not link with the displayed value processed with the digital filter. When you need a voltage or current output that links with the displayed value, use the optional voltage output card or current output card. For excitation voltage setting procedures, see Section 2.3, "Setting the excitation voltage". Plug in monitor outpu signal cables to the [+ +] and [-] terminals of the strain-gage-based transducer connector using the same procedures designed for the signal cables of the strain-gage-based transducer.

28 2 Installation and Wiring Connection of external control input The external control input circuit is classified into two types: no-voltage contact input type ( standard) and voltage input type (option). The no-voltage contact input type circuit inputs signals by short-circuiting/opening the path between the input and COM1 terminals. To conduct short-circuiting in this type, use contacts (e.g., relay and switch) and contactless outputs (e.g., open collector output). Shown below is the equivalent circuit of the no-voltage contact input type circuit. Inside of CSD V IN 1 ~ K COM1 CAUTION When signals are input based on the open collector output, use the sink type (minus common) for the connection. The no-voltage contact input type external control input circuit features internal power supply voltage of 12 VDC and short-circuit current of about 5 ma. For the voltage input type circuit, see Attachment L, "External Control Voltage Input Type Circuit (CSD )". 26

31 2 Installation and Wiring 2.3 Setting the excitation voltage [CF-07] With respect to the excitation voltage to the strain-gage-based transducer, you can select a voltage level of 2.5 VDC, 5 VDC, or 10 VDC. The excitation voltage should be set by using the C function CF-07. Shown below are the procedures for setting excitation voltage. POINT Changing the excitation voltage affects all calibration results stored to calibration numbers 0 to 3. For this reason, reexecute the calibration for numbers 0 to 3, respectively. When you enter Check mode, you can verify the excitation voltage currently set. For more information about Check mode, see Section 7.5, "Verification with Check mode". For more information about calibration procedures, see Section 3, "Calibration". 1. Press once to display. 2. Press once to change the display to. 3. Press. The C function mode is activated, and the display changes to a two-digit numerical value prefixed with [CF-]. 4. Using and, change the numerical value to and press. The following numerical value showing the currently set excitation voltage appears. Numerical value Excitation voltage 0 10 VDC 1 5 VDC VDC Default 10 VDC For setting procedures with and, see Section 1.6, "Basic key operation". 5. Using, set the excitation voltage and press. Whenever is pressed, the excitation voltage is cyclically changed from 0 to 2 in ascending order. 6. Press twice to return to Measurement mode. 29

32 3 Calibration 3 Calibration 3.1 Overview In either of the following cases, always calibrate the CSD-709 before use. Otherwise, you may obtain incorrect measurement resultss or the equipment may malfunction and cause damage to peripheral devices. Use the CSD-709 for the first time. Replace the strain-gage-based transducer or equipment. When incorrect measurement results are obtained, recalibrate the CSD-709. If you continue using the equipment without recalibration, it may malfunction and cause damage to peripheral devices. POINT WARNING When we have calibrated the CSD-709 in combination with a measuring unit (such as a strain-gage-based transducer), recalibration is not necessary. The CSD-709 can be calibrated in the following two ways. Calibration based on actual load Calibration based on input of numerical value In the calibration based on actual load, use a weight to adjust the load so that the input to the CSD-709 from the measuring unit will be correctly displayed on the CSD-709. If the CSD-709 is not calibrated: Load and decimal point display position are not displayed correctly. After the CSD-709 is calibrated: Correct load is displayed and the decimal point is placed in the correct position as set. 30

33 3 Calibration In the calibration based on input of numerical value, do not use a weight. Instead, manually enter the value to be input from the measuring unit to the CSD-709 through the front panel to adjust the value displayed on the equipment. In these two different types of calibrations, you should use the following procedures. Procedures common to actual load based calibration and numerical value input based calibration Changing the calibration number Setting of decimal point display position Setting of unit weight Setting of measuring weight Setting of weight mass Actual load based calibration Zero calibration based on actual load Numerical value input based calibration Entry of zero point Span calibration based on weight Entry of span Registration In these two types of calibrations, the actual load based calibration covers [zero calibration based on actual load] and [span calibration based on weight] and the numerical value input based calibration covers [entry of zero point] and [entry of span]. Which method you select is determined based on these factors: calibration conditions and whether the weight can be prepared. 31

34 3 Calibration Zero calibration based on actual load / Entry of zero point Normal zero calibration method is [zero calibration based on actual load]. Register the zero point with a tare or equivalent weight placed on the measuring unit. Zero calibration based on entry of zero point should be executed as long as all conditions listed below are met. The CSD-709 being used is replaced with another CSD-709. The zero calibration data (mv/v value) of the former CSD-709 is known. It is not possible to establish a no-load condition (initial condition including tare) for the measuring unit. Span calibration based on weight / Entry of span When it is possible to prepare a weight of at least two-thirds the measuring weight, execute [span calibration based on weight]. When there is no weight, execute [entry of span]. POINT When the span is input, the calibration accuracy is about 1/ If the accuracy of higher than 1/1 000 is required, execute [span calibration based on weight]. Whichever method you select, actual load based calibration or numerical value input based calibration, you can fine-tune the results to get more accurate values. 32

35 3 Calibration 3.2 Changing the calibration number [CF-18] The CSD-709 can store calibration results to four calibration numbers (0 to 3), respectively, and allows you to use the desired number by selecting it.

69 5 Settings Related to Detection Detection of a peak in the entire section To detect a peak with the entire section defined as the desired detecting section, set the following values to P functions PF-01 and PF-02, respectively. P function PF-01 (Detecting operation) PF-02 (Detecting section) Setting 00 (Peak) 0 (Entire section) Under these settings, the peak is determined as shown below according to the change in load. When the detection operation initiated through PEAK/TRACK input is generated by, for example, pressing, point A is determined as a peak. When the load changes thereafter and exceeds the value of point A, the peak changes according to the track, and, when the load reaches point B, the peak will be the value of point B. Similarly, when the load exceeds the value of point B, the peak changes according to the track. When the RESET input is generated by, for example, pressing, the process enters into the reset section and the displayed load becomes [0]. When the process leaves the reset section, it reenters the detecting section and the value of point D will be the peak until the PEAK/TRACK input is ended by, for example, pressing. 67

P function PF-01 (Detecting operation) PF-02 (Detecting section) Setting 01 (Bottom) 1 (Specified section) Under these settings, the bottom is determined as shown below according to the change in load. When the detection operation initiated through of PEAK/TRACK input is generated by, for example, pressing, point A is determined as a bottom. When the load changes thereafter and falls below the value of point A, the bottom changes according to the track, and, when the process enters into the hold section by, for example, pressing, the bottom will be the value of point B. When the process returns to the detecting section from the hold section, the value of point C is determined as a bottom. When the RESET input is generated by, for example, pressing in the detecting section, the process enters the reset section and the displayed load becomes [0]. When the RESET input is ended, the process reenters the detecting section, and, when the PEAK/TRACK input is generated by, for example, pressing, the process enters the hold section. When the RESET input is generated in the hold section, the detection process ends. 68

71 5 Settings Related to Detection Detection of a maximum in the time-specified section To detect a maximum with the time-specified section defined as the desired detecting section, set the following values to P functions PF-01, PF-02, PF-11, and PF-40, respectively.

When the detecting operation is initiated through input of PEAK/TRACK by, for example, pressing, the section within the detecting time already set is defined as the detecting section. When a maximum (point A) is detected in the detecting section, the subsequent section will be the hold section. When the RESET input is generated by, for example, pressing in the detecting section, the process enters the reset section and the displayed load becomes [0]. When the RESET input is ended, the process reenters the detecting section. When the RESET input is generated in the hold section, the detection process ends. 69

When the track exceeds the automatic start level, the detection operation is initiated and the section within the detecting time already set is defined as the detecting section. When an inflection point (point A) is detected in the detecting section, the subsequent section will be the hold section. When the RESET input is generated by, for example, pressing in the detecting section, the process enters the reset section and the displayed load becomes [0]. When the RESET input is ended, the process reenters the detecting section. When the RESET input is generated in the hold section, the detection process ends. 70

76 5 Settings Related to Detection Example of measurement in multimode This section shows a setting example where the following four detecting conditions are assigned to Areas 1 to 4 to execute operations in multimode. Detection of a peak in the entire section Detection of a bottom in the specified section Detection of a maximum in the time-specified section Detection of an inflection point in the automatic start time-specified section First, set the respective detection conditions while setting the detection condition numbers as described below. Set [0] to PF-09 and establish the conditions necessary to detect a peak in the entire section. Set [1] to PF-09 and establish the conditions necessary to detect a bottom in the specified section. Set [2] to PF-09 and establish the conditions necessary to detect a maximum in the time-specified section. Set [3] to PF-09 and establish the conditions necessary to detect an inflection point in the automatic start time-specified section. Upon completion of these settings, set the following values to PF-03, PF-90, PF-91, PF-92, and PF-93, respectively. P function PF-03 (Change to multimode) PF-90 (Area 1) PF-91 (Area 2) PF-92 (Area 3) PF-93 (Area 4) Setting 1 (Multimode) 0 (Detecting condition number) 1 (Detecting condition number) 2 (Detecting condition number) 3 (Detecting condition number) When you give the PEAK/TRACK input by, for example, pressing connected to the detection condition set to Area 1 after the establishment of settings, the detection is initiated. This time, operations triggered by the search conditions set to these areas are the same as those executed individually by means of the respective detection conditions.

77 5 Settings Related to Detection 5.3 Detection result judgment and waveform comparison The detection result judgment feature allows you to check that the peak in the detecting section is in a range from the upper limit set to P functionn P-51 to the lower limit set to P-52. Also, the waveform comparison feature allows you to check thatt the total value (track) from the start to end of measurement is in a range from the upper limit set to P-51 to the lower limit set to P-52 at the end of the detecting section or the completion of multimode. CAUTION The comparison of waveforms can only be executed on the CSD equipped with an optional memory card Detection result judgment [P-50], [P-51], [P-52] The detection result judgment feature can be used in the following sections. Entire section Specified section Time-specified section Automatic start time-specified section To execute the detection result judgment, set [1] (Detection result judgment) to P function P-50 and the upper and lower limits of judgment to P-51 and P-52, respectively. The result of the detection result judgment is obtained in the form of external control output by setting any of the following numerical values to F-70 to F-75. Numerical value Function 07 Shows the result of the detection result judgment is acceptable. 08 Shows the result of the detection result judgment is not acceptable. 09 Shows whether the result of the detection result judgment exceeds the upper limit. For settings related to the external control output, see Section 8.2, "External control output signal". When the detection is actually initiated, external control outputs to which [07] to [09] are set are turned offf between the start and end of the detecting section. When the detection is completed, results are output from those external control outputs to which [07] to [09] are set. In the following example, the result does not deviate from both the upper and lower limits and thus only the external control output to which [07] is set will be turned on after the detection. 75

78 5 Settings Related to Detection In the following example, the result exceeds the upper limit and thus external control outputs to which [08] and [09] are set will be turned on after the detection. In the following example, the result deviates from the lower limit and thus the external control output to which [08] is set will be turned on after the detection. As shown above, the detection result judgment allows you to judge that the peak is in the range determined by the upper and lower limits of the detecting section. Described below are setting procedures of the detection result judgment. 76

80 5 Settings Related to Detection The waveform comparison feature can be used in the following sections. Time-specified section Automatic start time-specified section To execute the waveform comparison, set [2] (Waveform comparison) to P function P-50 and the upper and lower limits of judgment to P-51 and P-52, respectively. The result of the waveform comparison is obtained in the form of external control output by setting any of the following numerical values to any function between F-70 and F-75. Numerical value Function 07 Shows the result of the detection result judgment is acceptable. 08 Shows the result of the detection result judgment is not acceptable. 09 Shows whether the result of the detection result judgment exceeds the upper limit. For the setting relative to the external control output, see Section 8.2, "External control output signal". The maximum for the data used in the waveform comparison is Therefore, the longest time that can be used in the comparison is determined by the AD sampling frequency set to C function CF-02, as shown below. Setting of CF-02 Setting details 0 (40 times/s) 100 s 1 (400 times/s) 10 s 2 (4 000 times/s) 1 s Default 0 (Disable) For this reason, when the detecting time of the time-specified section or automatic start time-specified section exceeds the maximum time, the data will be updated whenever the longest time has elapsed. When detection is actually initiated, external control outputs characterized by [07] to [09] that are set to any functions between F-70 and F-75 are turned off from the start to the end of the detecting section. When the detection is completed, results are output from those external control outputs to which [07] to [09] are set. In the following example, the result does not deviate from both the upper and lower limits and thus only the external control outputs to which [07] is set will be turned on after the detection. 78

81 5 Settings Related to Detection In the following example, the result exceeds the upper limit and thus external control outputs to which [08] and [09] are set will be turned on after the detection.

83 6 Settings Related to Comparison 6 Settings Related to Comparison 6.1 Overview The CSD-709 is equipped with a comparator that compares the track or peak to three preset values to turn on the open collector output when the track or peak deviates from this setting. You can set values used in the comparator in three stages: S0, S1, and S2. In addition, settings with respect to the comparator can be stored using four brand codes connected to four calibration numbers, 0 to 3. In the comparison with the comparator, use F function F-55 to set the F key function to the COMP setting mode and press to enter comparison values to S0 to S2, respectively. Select the track or peak as the target to be compared to S0 to S2 and set the operating conditions. For example, when you select the peak as the target to be compared to S1 and provide a setting such that the open collector output will be turned on when the displayed load becomes equal to or greater than S1, the open collector output is configured as shown below: Displayed load: Low S1 setting Displayed load: High S1 judgment display S1 open collector output ON OFF In the comparison with the comparator, you can set the delay based on the data width and duration. This delay suppresses the influence of noise to ensure an accurate comparison process. For example, [1] (Turn on the open collector output when the comparison target is equal to or greater than the comparison value) has been set, you can delay actual turn-on timing using the data width and duration. This operation is called [ON delay] By setting the ON delay appropriately, you can configure different open collector outputs, as shown below. Display Hysteresis data width S1 setting Hysteresis duration Time S1 open collector output when data width and duration are not set S1 open collector output when data width and duration are set ON OFF ON OFF 81

84 6 Settings Related to Comparison Similarly, if [2] (Turn on the open collector output when the comparison target is equal to or lower than the comparison value) has been set, you can delay the actual turn-on timing using the ON delay feature.

138 A Specifications of CSD-709 A.6 Function Analog filter A low-pass filter that utilizes resistors and capacitors to attenuate those frequency components higher than the set frequency. This filter is enabled only when the analog peak hold is used. Digital Filter A filter that stabilizes the fluctuation during the moving-average process with the CPU. Digital low-pass filter A low-pass filter used in the operation by the CPU. This filter attenuates those frequency components higher than the set frequency. (Bessel characteristic secondary low-pass filter) Simplified calibration Holding down,, and respectively for at least two seconds allows you to enter the desired parameter setting screen or calibration screen. Communication calibration You can execute the calibration based on communications through the interface (optional RS-232C, RS-422/485, or CC-Link) without key operation. CHECK value An additional load equivalent to the set value. Using this value, for example, in the pre-work check, allows you to confirm the original calibration status is maintained. Hold target change You can combine [Display], [Comparison output], [Current output (option)], [Voltage output (option)], [BCD output (option)], [CC-Link (option)], and [Serial interface (option)] to define the resulting combination as the hold target. Analog output target change You can select [Track] or [Peak] as the analog output target. Brand code change You can make the CSD-709 memorize up to four different types of calibration data or comparator settings, then select the desired item using functions or external control inputs (SEL.1 and SEL.2). Peak mode selection You can select the peak detection mode from 36 modes configured through a combination of nine hold modes (peak hold, bottom hold, peak-bottom hold, peak-to-peak hold, maximum hold, minimum hold, maximum-minimum difference hold, average hold, and four inflection point holds) and four section modes (entire section, specified section, time-specified section, and automatic start time-specified section). Digital peak hold You can acquire the peak load through high-speed sampling of up to times/s. Analog peak hold You can acquire the peak load more speedily independent of the sampling rate. However, the analog circuit equipped with capacitors is used to execute the peak hold, and thus there are some restrictions (e.g., the current load cannot be determined. Monitor output This function outputs approximately 2 V per 1 mv/v (when bridge power supply is 10 VDC.) before A/D conversion of the input signal from strain gage type transducer. Monitor mode This mode converts the load currently applied to the sensor into a value expressed in mv/v and displays the result. It is effective in finding the cause when the displayed load is abnormal or unstable. Waveform comparison After an additional memory (option) is mounted, you can judge the integrity of the measurements using upper and lower limits determined with the specialized application and comparison waveforms. Measurement result log After an additional memory (option) is mounted, you can record comparison judgment results as well as time stamps. 136
