13 4 GENERAL DESCRIPTION The Sentry Sample Sequencer is a microprocessor-based instrument capable of electronically switching up to eight sample streams one at a time to an analyzer and of providing signals to recorders. If a total of eight sample streams are not needed for one process, the remaining points may be assigned to additional analyzers, up to four in total. A Sentry manifold sampling valve specially designed to obtain optimum representative samples is available for sample stream switching with the Sample Sequencer. The Sample Sequencer reduces the number of required analyzers while maintaining equivalent data accuracy. Reliable sample analysis comparison is obtained by using a Sample Sequencer with one dedicated analyzer. In addition, significant operating cost savings are obtained by not having to install, maintain, and service multiple analyzers. The Sample Sequencer is capable of operating in the continuous mode for continuous analyzers or in the batch mode for batch analyzers. In addition, the Sample Sequencer is capable of measuring the analyzer analog output signal and converting the analog signal to digital data to be sent out using MODBUS TCP/IP or Embedded web using the Ethernet communication port. Using the MODBUS capability, one can connect to a PC or system network via the Ethernet cable to one or more Sequencers for remote monitoring, control, and data acquisition. Track and Hold outputs are available to provide independent outputs for each sample point. Digital outputs are also available to provide channel number indication as well as replicating analyzer alarms. Figures 1-3 illustrate a typical system arrangement for sample stream switching with the Sample Sequencer. Customer-supplied equipment is shown for clarification. 4.1 Modes of Operation The Sample Sequencer has two programmable modes of operation: BATCH Used for analyzers that take a sample "bite" (or batch), produce an analytical result, and then provide a contact signal output, in typically 1-20 minutes CONTINUOUS Used for analyzers that continuously produce an analytical result. NOTE If using the Sample Sequencer with a Hach analyzer, see Appendix B. SPD

17 4.2 Inputs and Outputs A variety of inputs and outputs are available on the Sample Sequencer Analog Inputs: Four analog inputs are located on the Sample Sequencer board for reading a 4 20 ma signal from up to four different analyzers. The Sample Sequencer converts this signal into Engineering Units for display and outputs the same signal for the Track and Hold analog outputs Analyzer Alarm Inputs: Four analyzer alarm inputs are located on the Sample Sequencer board. These inputs are typically used to indicate a loss of sample flow to the analyzer. An analyzer alarm will cause the analyzer description to flash on the operation screen. An analyzer alarm will also cause the digital alarm output for that sequencer to be set. When the Sample Sequencer is used in the Continuous mode, an analyzer alarm will immediately close the active sample valve and open the next sample valve. That sample valve will remain open until the analyzer alarm clears, one minute elapses, or if the sum of the sample and flush times is less than one minute when the timer expires. After one minute, the Sample Sequencer will open the next sample valve. The Sample Sequencer will continue trying to establish flow every minute until the analyzer alarm clears. When the Sample Sequencer is used in the Batch mode, an analyzer alarm will not immediately close the active sample valve. Instead, when the analyzer alarm is received, the Sample Sequencer will start a timeout timer. If the Sample Sequencer does not receive an End of Batch indication from the analyzer or the alarm does not clear before that timeout timer, the Sample Sequencer will close the current sample valve and open the next valve in the sequence. If the End of Batch indication is received before the timeout timer, the Sample Sequencer assumes the alarm is not a loss of flow and continues with normal operation. The operator can adjust the timeout timer by setting each sample s Sample Timer Calibration Hold Inputs: Four calibration hold inputs are located on the Sample Sequencer board. These inputs are used to indicate that the analyzer is performing a calibration. The calibration hold inputs do not perform a function when the Sample Sequencer is in the Batch mode. In the Continuous mode, the Sample Sequencer will wait at the active sample with the valve open when a calibration indication is received. Once the calibration indication clears, the Sample Sequencer will resume operation entering the Flush state for the sample that was active before the calibration hold indication was received End of Batch Inputs: Four End of Batch inputs are located on the Sample Sequencer board. These inputs are used to indicate when a batch type analyzer is finished taking a measurement. Without this input connected, the Sample Sequencer will never advance to the next sample when the Sample Sequencer is in the Batch mode. The End of Batch inputs are not used in the Continuous mode. SPD

18 4.2.5 Valve Outputs: Eight valve outputs are located on the Sample Sequencer board. These outputs supply 12 VDC to operate the sample valves. The eight valves may be divided between four analyzers in any combination Track and Hold Outputs: Eight analog outputs are provided on the Sample Sequencer board. These outputs are 4-20 ma outputs. When a valid reading is taken from the analyzer for a given sample, the Sample Sequencer updates ( Tracks ) the corresponding signal on the appropriate output. When the sample is not currently being analyzed, the Sample Sequencer Holds the corresponding signal on the appropriate output at its last known value Digital Outputs: A total of twelve digital outputs are available on the Sample Sequencer board. Four of these outputs are used to replicate the four-analyzer alarm inputs while the remaining eight are used for sample point indication. An on output indicates the point is currently being sampled and the analyzer reading corresponds to that sample point Ethernet Communications: The Sample Sequencer is capable of connecting to a network for communicating to a PC or control system via MODBUS TCP/IP. In addition, the sequencer provides the option to view settings via embedded web. For more information on these features, refer to Appendix D. 4.3 Optional Manifold Sampling Valve Although the Sample Sequencer may be used to control most manifold valve arrangements, the Sentry Manifold Sample Valve offers a convenient optional accessory to obtain a representative sample. The patented design incorporates block and bleed design and provides continuously flowing samples with no areas for cross contamination to occur. The valve is available in either four or eight sample line models. Contact Sentry for more information about this special sampling valve. 12 SPD

Selecting a widget will take you to its corresponding screen. Selecting the cancel button in the lower left corner will return you to the previous screen. Selecting the arrow button in the lower right corner will take you to additional widgets Flush Times Use this widget to update Flush Times. In Continuous mode, Flush Time is the amount of time the analyzer is flushed out before the analyzer reading is considered valid. The valve for the sample point is open during both the Sample Time and the Flush Time. In Batch mode, Flush Time is not used. Figure 10: Flush Times Screen To change Flush Time for a sample, touch the time that you would like to change. The Enter Time Screen will be shown. Enter the time desired using this screen; when finished, touch the enter button to update the value in the Flush Times Screen, or press the escape button to return to the Flush Times Screen without entering the value. Time values are limited to 59 minutes and 59 seconds. Once you have updated all the Flush Times, press the save button to save all times on the screen, or touch the escape button to leave the screen without saving the updated values. 18 SPD

25 5.2.6 Sample Times Use this widget to update Sample Times. Sample Time is the amount of time the analyzer is allowed to analyze the sample while the reading is considered valid. The Track and Hold value and Point Identification are active during the Sample Time. The valve for this sample point is open during both the Sample Time and the Flush Time. In Batch mode, Sample Time serves as a timeout timer that operates only when the analyzer is in alarm. While in alarm, if an End-of-Batch signal is not received before Sample Time times out, the Sample Sequencer will close the current sample point and proceed with the next sample point. Since the Analyzer Alarm input may serve to indicate more than a loss of sample flow, Sample Time should be set to give the analyzer sufficient time to attempt to complete an analysis and output an End-of-Batch indication. Figure 11: Sample Times Screen To change a Sample Time for a sample, touch the time that you would like to change. The Enter Time Screen will appear. Enter the time desired using this screen; when finished, touch the enter button to enter the value in the Sample Times Screen, or press the escape button to return to the Sample Times screen without entering the value. Time values are limited to 59 minutes and 59 seconds.

26 5.2.7 Bypass Sample streams may be temporarily skipped in the sequence by placing the sample point number in Bypass. If the Sample Sequencer is currently on a sample point that has been placed in Bypass, the Sample Sequencer will immediately skip to the next point in the sequence. Occasionally, it is necessary to hold an analysis on one sample point. To accomplish this, simply place all the undesired sample points in Bypass. Sample points are placed in either Sample or Bypass by using the Bypass Screen. Figure 12: Bypass Screen Touch the indicator for the sample line to be switched. This will toggle the sample line between Sample and Bypass. When a point that is placed in Bypass is next to be sequenced, the point will be skipped and the next point that is in Sample will be sequenced. Press the save button to save the changes made on this screen. To return to the previous screen without saving, press the escape button Mode The Sample Sequencer is capable of operating in two different modes, depending on the type of analyzer being used. Continuous mode is for continuous output analyzers such as sodium, conductivity, ph, O 2, some colorimetric, and many other analyzers. Batch mode is for analyzers that take a "bite" or batch of sample and then spend some time analyzing it before outputting a new fixed analog signal. These typically include silica, phosphate, and other analyzers. (Consult specific analyzer documentation to determine the type of analyzer.) The mode is changed from the Mode Screen. 20 SPD

41 5.3 Operating Modes Continuous Mode This mode is for continuous output analyzers such as sodium, conductivity, ph, O 2, some colorimetric, and many others. Timing Considerations for the Continuous Mode Figure 36 illustrates the timing diagram for the continuous mode. The following considerations should be made when determining the timing for your system. Analyzer Alarm: An analyzer alarm will immediately close the active sample valve and open the next sample valve. That sample valve will remain open until the analyzer alarm clears or one minute elapses. After one minute, the Sample Sequencer will open the next sample valve. The Sample Sequencer will continue trying to establish flow every minute until the analyzer alarm clears. Calibration Hold: A calibration hold signal will cause the Sample Sequencer to wait at the active sample with the valve open. Once the calibration indication clears, the Sample Sequencer will resume operation entering the Flush state for the sample that was active before the calibration hold indication was received. Flush Time: After switching to a successive stream, there will be a settling time for the analyzer to stabilize to the new sample. The analyzer analog output signal is ignored during this time. The necessary Flush time depends on the valve manifold design, sample line length from the manifold arrangement, sample velocity and analyzer response time. Sample Time: Sample Time is the time period during which a valid analyzer signal is read. Analog outputs are updated and point identification relay contacts are closed during this time. The necessary Sample time should be set long enough to recognize stable readings and to provide recording devices time to capture the data. SPD

42 Figure 36: Continuous Mode Timing Diagram 36 SPD

43 5.3.2 Batch Mode This mode is for analyzers that take a "bite" or batch of sample and then spend some time analyzing it before outputting a new fixed analog signal. Typical types are reagent additive, chromatographs, etc. When these analyzers have completed an analysis there is just one output value until the analyzer's next cycle is completed. An "End-of-Batch" contact closure signal must be provided at the conclusion of a batch by the batch type analyzers. The Hach Series 5000 analyzer operates in this manner. See Appendix B for instructions about connecting a Hach 5000 analyzer to the Sample Sequencer. Timing Considerations for the Batch Mode Figure 37 illustrates the timing diagram for the batch mode, showing how each sample stream is switched when the analyzer outputs an end-of-batch signal to the Sample Sequencer. If the Sample Sequencer does not receive an end-of-batch signal, the Sample Sequencer will never advance to the next sample. Upon receiving an end-of-batch signal from the analyzer, the Sample Sequencer reads the analyzer value, updates the Track and Hold output, and closes the point identification relay. Note: The updated Track and Hold output and point identification relay are for the previous sample point. The open valve number will never match the closed relay point identification in the batch mode. The following considerations should be made when determining the timing for your batch mode system: End-of-Batch: The Sample Sequencer receives this signal when the analysis is completed and the analyzer is ready to begin a new analysis. Analyzer Alarm: The Sample Sequencer receives this signal when the analyzer is in alarm, such as a loss of sample flow condition. Once the analyzer alarm signal is received the Sample Sequencer will start the Sample timer, and replicate the analyzer alarm for use by external recorders and control systems. Sample Time: The Sample time in the batch mode is a timeout timer that operates only when the analyzer is in alarm. While in alarm, if an End-of-Batch signal is not received before the Sample time times out, the Sample Sequencer will close the current sample point and proceed with the next sample point. Since the Analyzer Alarm input may serve to indicate more than a loss of sample flow, the Sample time should be set to give the analyzer sufficient time to attempt to complete an analysis and output an End-of-Batch indication.

These outputs provide 12 VDC to control solenoid valves. Sentry offers a manifold sample valve for use with the Sample Sequencer. With additional hardware, other solenoid valve operating voltages may be used. 38 SPD

50 6.3.1 Power Connection The Sample Sequencer contains a universal power supply. The power supply is capable of accepting an input voltage range of VAC and frequency of 50 or 60 Hz. The Sample Sequencer will automatically operate with power supplied in this range. A power supply lead of 16 AWG (1.3 mm 2 ) copper wire is recommended. It is recommended the Sample Sequencer be connected to an electrical outlet or outlet strip with surge suppression and filtering. A suitable external over-current protection device such as a fuse (Class CC, 2A, Time delay) or circuit breaker (C trip curve, 2 A) is recommended for both the hot (L) and neutral (N) leads. Using this method, the plug will serve as the disconnect device. A 16 AWG, 60 o C, VW-1, 600V, type SJT cord is recommended for non-detachable connections. For permanent connections the use of a flexible S0W cable or better must be used. Sizing must be in accordance to the CEC. The mains and output terminal are rated within the following condition: Mains terminals rated up to 300V, 10A, AWG, PA insulating material, Inflammability class V0, Type: Plug, 3 position, and screw connection. Output terminals rated up to 300V, 8A, 14-30AWG, PA insulating material, Inflammability class V0, Type: Plug, 6 or 8 position, and screw connection. For permanently connected installations: - A switch or circuit breaker shall be included in the building installation. - It shall be in close proximity to the equipment and within easy reach of the OPERATOR. - It shall be marked as the disconnecting device for the equipment. The cord and plug shall comply with the following standards: Table 2: Power Cord Requirements Location Cord Plug United States ANSI/UL 817 ANSI/UL 498 Canada CSA C22.2 No. 21 or CSA C22.2 No. 21 and C22.2 No. 42 C22.2 No. 49 European Community IEC or Appropriate IEC standard If desired, the Sample Sequencer may also be hard wired to instrument-quality power using appropriate certified conduit, fittings, and wiring. A suitable external over-current protection device, such as a fuse (Class CC, 2A, Time delay) or circuit breaker (C trip curve, 2 A), and disconnect device is recommended. The over-current protection and disconnect devices shall be installed on both the hot (L) and neutral (N) leads. The disconnect device shall be located near the equipment and marked with appropriate ON(1) OFF(O) markings as specified by local codes. For fixed wiring methods, the ground conductor shall have green with a yellow stripe as the insulation. During connection of the power wire the grounding lead must be suitably routed and long enough so that it is the last conductor to take the strain. Installation should be performed by qualified personal in accordance with local codes and procedures. Figure 44 shows the power connections on the board. 44 SPD

51 Figure 44: Grounding I/O Cable Grounding and EMC Considerations To maintain CSA and CE ratings for EMC, all I/O cables must be shielded and grounded according to Figure 44. In addition, I/O cables must use ferrites to reduce EMI. To properly ground the Sequencer, a ring terminal ground lug should be connected to your ground wire and secured to the enclosure ground stud, which is marked with a ground symbol and located next to the customer power connection. For an insulated ground conductor, use a green or green with yellow stripe conductor which is the same size as the mains conductor. SPD

52 6.4 Sequencer Board Connections The Sample Sequencer provides digital outputs to indicate the current active channel. These connections may be used with a recorder or in situations where analog I/O at the receiving device is limited. In addition to these point identification contacts, replicated analyzer alarms are also located on the board. Figure 45 shows typical connections. Figure 45: Sequencer board connections Valve Output Connections The valve outputs of the Sample Sequencer output 12 VDC, intended for use with the Sentry Manifold Sample Valve. Other manifold valves may be used; however additional hardware such as interposing relays may be required.
