General Description
The Sentry Sample Sequencer 6 reduces the number of required analyzers while maintaining equivalent data accuracy.
Electronically switches up to eight sample streams, one at a time, to a shared analyzer and provides signals to
recorders.
If eight sample streams are not needed for one process, four to eight points may be assigned to one.
Track and hold outputs provide independent outputs for each sample point to remote data acquisition devices
(DCS, recorder, etc.).
Digital outputs provide channel number indication and/or replicate analyzer alarms for remote data.
Measures the analyzer analog output signal and converts the analog signal to digital data.

8 Sentry Equipment Corp
Modes of Operation
The Sample Sequencer 6 has two programmable modes of operation:
Continuous mode is used for analyzers that continuously produce an analytical result.
Batch mode is used for analyzers that take a sample“bite”(or batch), produce an analytical result, and then provide
a contact signal output, typically in 1-20 minutes.
Figure 1 illustrate typical system arrangements for sample stream switching with the Sample Sequencer 6. Customer-
supplied equipment is shown for clarication.

Sentry Sample Sequencer 6 Controller 9
ÂNOTE
See Appendix C on page 37 for interface protocols and wiring for a number of typical analyzers. If using the Sample
Sequencer 6 with a Hach analyzer, see Appendix B on page 33.
Inputs and Outputs
A variety of inputs and outputs are available on the Sample Sequencer 6. The Sample Sequencer 6 is a modular
design utilizing dedicated IO boards. Up to two IO boards can be tted into each enclosure. Up to eight IO boards
can be equipped with one Sample Sequencer 6. This solution would utilize 4 enclosures, one with the CPU and
communication board and 3 IO extender enclosures. In general one IO board corresponds to one four output manifold.
Analog Inputs
Up to two analog inputs are located in the sequencer enclosure for reading 4–20 mA signals from up to two dierent
analyzers.
The sequencer converts 4–20 mA signals into engineering units for display, and outputs the same signals for the
track and hold analog outputs.
Analyzer Alarm Inputs
Alarm inputs are typically used to indicate a loss of sample ow to the analyzer.
Two analyzer alarm inputs are located in the sequencer enclosure.
Alarm inputs cause the digital alarm output for that sequencer to be set.
In Continuous mode:
1. An alarm immediately closes the active sample valve and opens the next sample valve.
2. The next sample valve remains open until one of the following occurs:
a. the alarm clears
b. one minute elapses
c. the timer expires
3. After the sample valve closes, the sequencer opens the next sample valve.
4. The sequencer continues trying to establish ow until the analyzer alarm clears.
In Batch mode:
1. An alarm starts a timeout timer. (The operator can adjust the timeout timer for all samples simultaneously by
setting the sample timer.)
2. If the sequencer does not receive an end-of-batch indication from the analyzer, or if the alarm does not clear
before the timer expires, the sequencer closes the current sample valve and opens the next valve in the
sequence.
3. If the end-of-batch indication is received before the timer expires, the sequencer assumes the alarm is not a loss
of ow and continues with normal operation.

Calibration Hold and End-of-Batch Inputs
A calibration hold input indicates that the analyzer is performing a calibration.
Two calibration hold inputs are located in the sequencer enclosure.
In Continuous mode, when a calibration hold input is received:
– The sequencer waits at the active sample with the valve open.
– Once the calibration hold clears, the sequencer resumes operation, entering the Flush state for the sample that
was active before the calibration hold was received.
In Batch mode, calibration hold inputs do not perform a function.
Two end-of-batch inputs are located in the sequencer enclosure.
Without this input connected, the Sample Sequencer 6 does not advance to the next sample when the sequencer is
in Batch mode.
End-of-batch inputs are not used in Continuous mode.
Valve Outputs
Valve outputs supply 12 or 24 VDC to operate the sample valves.
Up to eight valve outputs are located in the sequencer enclosure.
The eight valves may be divided between two analyzers sequentially.
Track and Hold Outputs
Eight analog outputs (4–20 mA) are provided in the sequencer enclosure.
When a valid reading is taken from the analyzer for a given sample, the Sample Sequencer 6 tracks (updates) the
corresponding signal on the appropriate output.
When the sample is not currently being analyzed, the sequencer holds the corresponding signal on the appropriate
output at its last known value.
Digital Outputs
A total of eight digital outputs are available per IO board:
Four outputs are used to replicate the four analyzer alarm inputs
Four outputs are used for sample point indication.
An LED above the output indicates that the point is currently being sampled and the analyzer reading corresponds
to that sample point.
Ethernet Communications
The Sample Sequencer 6 is capable of connecting to a network for communicating to a PC or dedicate terminal
screen via a webpage.
Modbus communication protocol is available on request. Please contact Sentry for further information.
