Product Description A-96.250.661 / 120418 7 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 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 I2C interface. For further information see Connect the I2C Bus, p. 31.  Internal Set the AMI Sample Sequencer to the mode 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.

AMI Sample Sequencer 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].

Measuring Cycle at Batch Measurement 2.1.1 AMI Silica and AMI Phosphate HL Example with two sample streams: A measuring cycle always starts when the solenoid valve [C] clos- es. NOTICE: • The different squares, black with/without underline and white with/without underline are displayed on the display of the AMI Sample Sequencer, for better understanding they are integrated in the illustrations below. • The meaning of the different squares is explained in chapter 5, Operation. Step 1 The solenoid valve [C] is open.  The 6-way valve [A] is on position 1 and the sample stream 1 flows via constant head [B] through the photometer [D]. No measurement is performed at this time.

AMI Sample Sequencer Product Description 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 . 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).

The sample stream number corresponds with the channel number. The functionality of the inputs depends on the settings of the Mode of the AMI analyzer. Mode Internal If the AMI analyzer is set to Mode Internal, the programmed num- ber of sample streams is sequentially measured. Any sample inlet can be deactivated by closing one or more of the contacts 9 to 14 (6 inputs from PLC) via a PLC. In the example below, the channels highlighted in red will not be measured.

AMI Sample Sequencer Installation Mode External If the AMI analyzer is set to mode external, each sample stream to be measured has to be activated by closing the respective contact. In the example below, the sample stream 3 (CH3) highlighted in green will be measured as soon as the AMI analyzer has finished the previous measurement. NOTICE: • Closing more than one of the inputs will cause an undefined state. • If all inputs are open the AMI analyzer switches to standby mode. Connect the signal inputs according to the connection diagram. Mode Fieldbus The same function as External but using Profibus or Modbus proto- col.

AMI Sample Sequencer Installation 3.9. Communication, Error Handling 3.9.1 Mode The I2C connection allows a communication between the AMI ana- lyzer and the AMI Sample Sequencer. Sample Switch Command The AMI analyzer sends a command to the AMI Sample Sequencer to switch the 6-way valve to the next sample stream. Sample Flow Error in Mode Internal If the Sample Sequencer detects a flow error on a sample stream, it immediately switches to the next sample stream until it finds a sam- ple stream with sample flow. The flow error is indicated on the re- spective sample stream on the AMI analyzer display with a tilde. During this time the AMI analyzer detects sample flow from the con- stant head, therefore no flow alarm is triggered. Sample Flow Error in Mode External If the Sample Sequencer detects a flow error on a sample stream, it is waiting for the command to switch to the next sample stream. A flow alarm is issued via relay contact 7 “ALARM” of the outputs to PLC. 3.9.2 Mode The signal outputs 1 and 2 of the AMI analyzer can be connected to the signal inputs 1 and 2 of the AMI Sample Sequencer. This allows to transfer the measuring values of each measured sample stream to a remote device. There is no communication between the AMI analyzer and the AMI Sample Sequencer! Sample Switch Command The command to switch to the next channel is triggered by the AMI Sample Sequencer according to its programmed cycle time. Sample Flow Error If the Sample Sequencer detects a flow error on a sample stream it remains on this sample stream until the cycle time is over. During this time it displays a flow alarm.

Instrument Setup A-96.250.661 / 120418 45 4. Instrument Setup After the installation according to checklist has been finished, ad- just the sample flow. Without back pressure regulator 1 Open all main sample taps. 2 Open all flow regulating valves at the sample inlets of the AMI Sample Sequencer. 3 Adjust the sample flow of each sample inlet to min. 5 l/h. 4 Check all sample inlets for leakage. 5 If leakage occurs, stop sample flow and repair it. 6 Repeat step 1 to 4. 7 Switch on power. With back pressure regulator The SWAN Back Pressure Regulator is used to stabilize, reduce and control the flow rate of sample for water analyzing systems. If a back pressure regulator is installed adjust the sample flow as fol- lows: 1 Open all main sample taps. 2 Open all flow regulating valves at the sample inlets of the AMI Sample Sequencer. 3 Open the shut off valves on the back pressure regulators. 4 The sample flow of each sample inlet should be min. 5 l/h. 5 Check all sample inlets for leakage. 6 If leakage occurs, stop sample flow and repair it. 7 Repeat step 1 to 5. 8 Switch on power. 4.1.
