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.
