  • Page 26: Operating Modes

    Sample Sequencer OPERATING MODES: OFF, CYCLE, BATCH If there are no sample points on, or if a BATCH time out has occurred, or calibration has been used, or after eight successive analyzer alarms, the Sample Sequencer goes into the OFF mode. This is the normal preferred standby mode.
  • Page 27 Sample Sequencer Operation minute or more for stream switching. The analyzer analog output signal is ignored during the delay time. The necessary delay depends on the valve manifold design, sample line length from the manifold arrangement, sample velocity, analyzer response time, sample constituents and differences between the amount of constituents for each sample point.

  • Page 29: Batch

    Sample Sequencer BATCH The 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. 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, (as opposed to a continuous analyzer that shows the contemporary trend.) The Hach Series 5000 analyzer operates in this manner.

  • Page 30: Turning Sample Streams On & Off

    Sample Sequencer Timing Considerations for the Batch Mode: Figure 9 illustrates the concept of cycle, delay and dwell times for the batch mode of operation. Figure 9 demonstrates how each sample stream is switched when the analyzer outputs an "end- of-analysis"...

  • Page 31: Advancing Streams

    Sample Sequencer Operation Advancing Streams Sample streams may be advanced to any desired point number. Turn on the desired sample point number by pressing the respective sample point number switch (1-8) and verifying the adjacent point light is on. Then, turn off the intermediate point numbers and press the START/RESET key. The desired sample point number will be on.
  • Page 32 Sample Sequencer Operation defeats the purpose of the Sequencer's analog alarms and may make the Sample Sequencer go into the Off mode erroneously. The analyzer system alarm is annunciated by the Analyzer Alarm light on the Sequencer display (see Figure 6). The light will remain on until the analyzer system alarm stops. This alarm is also annunciated by the commutating normally-open alarm contacts on the optional Signal switching output board and 0-1 VDC Signal output boards.
