2. Product Description
Application
Range
The AMI Sample Sequencer is a complete system for the automat-
ic, continuous multiplexing of up to six sample streams to one pro-
cess analyzer. The AMI Sample Sequencer can be connected to
an:
AMI Phosphate HL
AMI Silica
AMI Silitrace
AMI Sodium A
AMI Sodium P
Operating
Modes
The AMI Sample Sequencer provides the following two operating
modes

AMI
Set the AMI Sample Sequencer to the mode <AMI> if it is con-
nected to an AMI Phosphate HL, AMI Silica or AMI Silitrace. In
this operating mode the AMI Sample Sequencer works as
slave, either of the analyzer or of an external PLC. Communi-
cation between the instruments takes place via I
2
C interface.
For further information see
Connect the I2C Bus, p. 31 .
 Internal
Set the AMI Sample Sequencer to the mode <Internal> if it is
connected to an AMI Sodium A or AMI Sodium P. In this oper-
ating mode the AMI Sample Sequencer works as master. It
switches the sample streams according to the programmed
cycle time. There is no communication between the instru-
ments, only measuring values are transferred via signal out-
puts 1 and 2 of the analyzer to the signal inputs 1 and 2 of the
AMI Sample Sequencer. For further information see
Sample Sequencer Inputs, p. 37 .
Signal
Outputs
6 current outputs to transfer the measuring values of the AMI trans-
mitter to a PLC device.
Relay 6 signal outputs for indication of the 6-way valve position.
1 signal output for flow alarm.
Inputs 6 signal inputs to override programmed measuring sequences, by
activating or deactivating an input. The functionality depends on the
settings of the instruments.

Product Description
Safety
Features
No data loss after power failure. All data is saved in non-volatile
memory. Over voltage protection of in- and outputs. Galvanic sepa-
ration of measuring inputs and signal outputs.
Fluidics The sample enters the flow cell blocks [C, D, E] via the sample in-
lets [I]. Each sample inlet is equipped with a flow regulating valve
[G]. The sample flows through the active sample line via 6-way
valve [A] and flow meter [F] to the instrument. Excessive sample
(e.g. inactive sample lines) flows via overflow [H] to the atmospher-
ic drain [J].

Example with two sample streams:
A measuring cycle always starts when the solenoid valve [C] clos-
es.

2.2. Measuring Cycle at Continuous Measurement
2.2.1 AMI Sodium A and AMI Sodium P
A new measuring cycle always starts when the 6-way valve [A] is
switched to the next programmed sample stream.
NOTICE: The following parameters are only available if the AMI
Sample Sequencer is set to the mode <Internal>.
Cycle time The time of switch over between the sample streams is defined as
-cycle time-. The cycle time includes the “Flush Time” and the mea-
suring time of the active sample line.
The measuring time can not be set, but can be calculated as fol-
lows:
Measuring time = “Cycle Time” - “Flush Time” + “Valid After”
The -cycle time- can be set individually for each sample line in 5
min steps from 5 min to 600 min. A sample line is deactivated if the
cycle time is set to 0 min.
Flush Time The parameter -Flush Time- defines how long the measuring cell of
the AMI Sodium A or an AMI Sodium P is flushed with the active
sample before the measurement starts. (see 5.1 Sequence, p. 60)
Valid After The parameter -Valid After- defines the remaining measuring time
of the sample stream x after the 6-way valve has switched to the
next sample stream (see 5.1 Sequence, p. 60).
