Sample Sequencer Operation Membrane Switch Keys Sample Point Numbers (1-8): The eight sample point number switches turn a sample point on or off. When the point is on, the adjacent LED will light and the sample point will be analyzed sequentially. DISPLAY: Pressing this key causes the function as indicated by the function lights to advance to the next one down and back to the top.
Sample Sequencer Operation To Program: • Press the DISPLAY key to select desired function. To select desired POINT number for the low and high alarms press the NEXT key. • Press PROGRAM. The programming arrows light up and the current programmed value is displayed. • Starting at the right digit, pressing the key immediately above the up arrow (DISPLAY) causes the digit to increment. Press repeatedly until the desired digit is displayed.
Sample Sequencer Operation Display Functions: Functions shown in Figure 6 may be displayed on the Sample Sequencer. Pressing the DISPLAY key toggles through the below functions. The light adjacent to the display function lights to indicate the function is displayed. The NEXT key toggles through successive function point numbers (1-8) for ANALOG mA, LOW ALARM and HIGH ALARM.
Sample Sequencer Operation PROGRAM key on the Sample Sequencer. The programming procedure is similar to that described for programming the alarms. See the manual section on communications for more information about the network communications. SENTRY Equipment Corp • P. O.

Sample Sequencer Operation OPERATING MODES: OFF, CYCLE, BATCH OFF 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. Even when the unit is "OFF", it is still able to: Program Calibrate Communicate A local or remote START/RESET starts the Sequencer again.
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.
Sample Sequencer Operation FIGURE 8 - Cycle Mode Timing Diagram SENTRY Equipment Corp • P. O. Box 127 • Oconomowoc, WI 53066 • 262/567-7256 • FAX: 262/567-4523 Web: www.sentry-equip.com • e-mail: sales@sentry-equip.
Sample Sequencer BATCH Operation 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.
Sample Sequencer Operation 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 "endof-analysis" signal to the Sample Sequencer. If the Sample Sequencer doesn't receive an end-ofanalysis before the cycle time expires, the Sequencer goes into the off mode and the analyzer alarm light on the front display goes on.
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. Turn on previous sample points which are desirable.
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.
Sample Sequencer Operation Sample Nametag Figure 10 shows the sample nametag which may be removed from the rear of the display assembly by removing the front display bezel and four screws. The bezel may be snapped off by lightly prying with a flat screw driver on one of the corners. The nametag slips into the pocket on rear of the display. One may type the desired sample names slightly above the respective lines and insert the nametag back into the display. Sample number one is on the top line.
