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 clarication.

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 dierent
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.
10 Sentry Equipment Corp
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.
Sentry Sample Sequencer 6 Controller 11
For more information on these features, refer to Appendix D on page 39.
Optional Manifold Switching Valve
The Sample Sequencer 6 may be used to control most manifold valve arrangements; however, the Sentry Manifold
Switching Valve is a convenient optional accessory for obtaining representative samples.
The patented Sentry Manifold Switching Valve
incorporates block and bleed design
provides continuously owing samples
eliminates areas where cross contamination can occur
available in either four or eight sample line models
Contact Sentry Equipment for more information about this optional sampling valve.

Electrical Connections
Electrical Shock Hazard – All input and output wiring should be installed in such a manner that access to bare copper is
prohibited during normal operation.
IcoTek KEL-DPZ 24/26 and KEL-ER 24/10 multi-membrane cable entry plates are provided on the bottom and right
side of the enclosure for up to 26 cables with 5 - 10.2mm cable diameter.
On the left side of the enclosure, cable entries are provided for the ethernet connection.
Figure 9 (board view) and Figure 10 (schematic view) show the power connections on the board.
Power Connection
The Sample Sequencer 6 uses a universal power supply that accepts an input voltage range of 85-305 VAC and
frequency of 47-440 Hz. A power supply lead of 12-24 AWG (4-0.25 mm2) copper wire is recommended.
Connect the sample sequencer to an electrical outlet or outlet strip with surge suppression and ltering. Using this
method, the plug serves as the disconnect device.
A 12-24 AWG, 60°C, VW-1, 600V, type SJT cord is recommended for non-detachable connections.
For permanent connections, use a exible SOW cable or better. Sizing must be in accordance to the CEC.
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.
The mains and output terminal are rated within the following condition:
Mains terminals rated up to 300V, 17.5A, 12-30 AWG, PA insulating material, Inammability class V0, Type: Plug, 8
position, and screw connection.
Output terminals rated up to 300V, 17.5A, 12-30 AWG, PA insulating material, Inammability class V0, Type: Plug, 8

United States ANSI/UL 817 ANSI/UL 498
Canada CSA C22.2 No. 21 or C22.2 No. 49 CSA C22.2 No. 21 and C22.2 No. 42
European Community IEC 60227 or 60245 Appropriate IEC standard
If desired, the Sample Sequencer 6 may also be hard wired to instrument-quality power using appropriate certied
ttings, 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(|) OFF(O) markings as
specied by local codes.
For xed wiring methods, the ground conductor shall have insulation with a continuous outer nish that is either
green, or green with one or more yellow stripes.
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 qualied personal in accordance with local codes and procedures.
Grounding and EMC Considerations
Power
To properly ground the Sample Sequencer 6:
• Use an insulated ground conductor that has a green or green with one or more yellow stripes and is the same size
as the mains conductor, and land the conductor on the“EGND”terminal on the power board.
I/O Cables
To maintain SGS and CE ratings for EMC:
All I/O cables must be shielded and grounded.
The shield (drain) wire for the analyzer inputs must be tied to an isolated ground located near the opposite cable
end (analyzer) from the sequencer, and not connected to the sequencer.
Sequencer Board Connections
Make sure all leads are lugged prior to wiring to the terminal blocks.This avoids the potential for miswiring and placing
transients on the analyzer(s) and sequencer. Be sure to ground the shield in the analyzer as detailed in“Grounding and EMC
Considerations”on page 16.
Sentry Sample Sequencer 6 Controller 17
Connections from the Analyzer(s)
Referencing Figure 10, analyzer connections include:
4–20mA output signals
analyzer alarm (typically a loss of ow or system failure alarm)
end-of-batch signal for batch analyzers
calibration signal for continuous analyzers
Use a 22 AWG multiple twisted pair shielded cable similar to Belden 9512 for each analyzer connected. This allows the
signals to be connected from each analyzer to the sequencer with one cable (seeFigure 9).
Analog Outputs from the Sequencer (Track and Hold)
Analog outputs (Track and Hold, 4–20 mA) are created for each sample being sequenced through the analyzer(s).
Outputs provide individual sample line data acquisition for local or remote indication.
Connections may be used with a recorder or in situations where analog I/O at the receiving device is limited.
Use a 22 AWG 4 pair twisted pair shielded cable similar to Belden 9514 for wiring to each removable terminal block.
Maximum load is 400 ohms. (See“Specications”on page 6 for additional details.)
Digital Outputs from the Sequencer
The Sample Sequencer 6 has 16 sinking digital outputs to provide point indication for sample being analyzed:
eight (8) per I/O board
four (4) replicated analyzer alarms
four (4) point indication
Use a 22 AWG multi-conductor shielded cable similar to Belden 9423 for wiring to each removable terminal block.
Valve Output Connections
The valve outputs of the Sample Sequencer 6 output 12 or 24VDC, and are 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.
Use an 18 AWG multi-conductor shielded cable similar to Belden 9409 for wiring to each solenoid valve used. Typical
valve connections are shown in Figure 10.
