AMI Silica
Product Description
2. Product Description
Application The AMI Silica is a complete monitoring system for the automatic,
Range continuous measurement of the silica content in water of power
plants or demineralizer plants.
Silica The determination of silica is done by the photometric analysis of
Measurement molybdate blue at 820 nm.
Silica and ortho-phosphates react at low pH with ammonium mo-
lybdate to the yellow colored molybdosilic acid respectively molyb-
dophosphoric acid. The molybdophosphoric acid is destroyed with
oxalic acid before the molybdosilic acid is reduced with iron-(II)-am-
monium-sulfate to the heteropoly-blue complex.
The required reagents are added in four steps to the sample in the
photometer, where they allow a precise measurement of the silica
content in the sample after the chemical reactions has been fin-
ished.
Grab Sample The measuring mode grab sample allows the measurement of
samples from remote locations.
Second Sam- If required the AMI Silica can be equipped with the optional second
ple Stream sample stream module.
Sample Se- If measurement of more than two sample streams is required, the
quencer AMI Silica can be connected to a Sample Sequencer which allows
to measure up to six sample streams.
Signal Two signal outputs programmable for measured values (freely scal-
Outputs able, linear or bilinear) or as continuous control output (control pa-
rameters programmable).
Current loop: 0/4–20 mA
Maximal burden: 510
Third signal output with the same specifications as option.
(Only possible if no communication interface is used.)
Relay Two potential-free contacts programmable as limit switches for
measuring values, controllers or timer for system cleaning with au-
tomatic hold function.
Maximum load: 1 A / 250 VAC

AMI Silica
Product Description
Fluidics The sample flows into the constant head [A] via the sample inlet [B]
and the flow regulating valve [C]. Adjust the flow regulating valve so
that always a small part of the sample flows through the overflow
tube [E] into the waste [V]. This adjustment ensures a sufficient
sample flow through the measuring chamber [L] of the photometer
[H].
If no measurement takes place, the sample flows through the pho-
tometer outlet [G] where it will be aerated through air inlet [F] to
generate bubbles. Then the sample flows through the bubble coun-
ter [P] into the waste [V].
If a measurement cycle starts, the solenoid valve [D] is activated
and the sample inlet [M] to the photometer is closed. The 6-way
valve is automatically rotated to position 1 and a precisely defined
quantity reagent of the container [Q] is pumped into the measuring
chamber by the peristaltic pump [J]. Immediately after that the
6-way valve is rotated in position 2 and the reagent 2 from contain-
er [R] is pumped into the photometer and mixed with the reagent 1
and the sample by the magnetic stirrer [N]. This procedure is re-
peated with the 6-way valve in position 3 and reagent 3 and 6-way
valve in position 4 and reagent 4.
After the measurement has been finished, the solenoid valve opens
and the measuring chamber is flushed.
The position 6 of the 6-way valve is not used.

SEQUENCER
Mode External In the mode External, the AMI Silica works as a slave. It is con-
trolled by the Sample Sequencer. The Sample Sequencer in turn is
controlled via an external PLC.
For example, if sample stream 1 of the Sample Sequencer is ac-
tive, the AMI Silica measures the probe of the sample stream 1 until
the sample stream of the Sample Sequencer changes to the next
programmed channel. The current measurement is completed be-
fore the channel is switched.
Mode Fieldbus The AMI Silica is controlled via fieldbus.

3.1 Calibration
3.1.5 Performs a calibration using the standard solution. Follow the in-
struction on the screen. See Calibration, p. 42
3.2 Service
3.2.1 Verification: Performs a verification using the verification kit.
Follow the instruction on the screen. See Verification, p. 41.

netic valve 1/2 with the up/down keys. Then press <Enter> to
change the setting or value. After confirming the setting with the
Enter key, the value is simulated by the relay/signal output.

4.1 Grab Sample
4.1.5 Starts a grab sample measurement. Follow the instruction on the
screen. See Grab Sample Measurement, p. 37
4.2 Sensors
4.2.1 Filter Time Constant: Used to damp noisy signals. The higher the
filter time constant, the slower the system reacts to changes of the
measured value.
Range: 5–300 Sec
4.2.2 Hold after Cal: Delay permitting the instrument to stabilize again
after calibration. During calibration, verification or grab sample plus
hold-time, the signal outputs are frozen (held on last valid value),
alarm values, limits are not active.
Range: 0–6‘000 Sec

5 Installation
5.1 Sensors
5.1.1 Ref. Verification: Set absorbance value of verification kit according
to label.
Range: 0.200–0.600
5.1.2 Standard: Set the value in ppb of the standard you use for calibra-
tion.
Range: 50 ppb–5 ppm
5.1.3 Channels: Choose between 1 channel or 2 channel measurement.
If a Sample Sequencer is connected, up to 6 channels can be cho-
sen.
If 2 channels are selected, the transmitter switches automatically
between the channels after each measurement.
5.1.4 Channel Selection: This menu is only visible if <Channels> is set to
2, or if a Sample Sequencer is connected to the AMI Silica. The fol-
lowing 3 operating modes can be set:
Internal
External
Fieldbus
Mode Internal: In this mode, the AMI Silica sequentially measures
each single sample stream of the Sample Sequencer or switches
automatically between channel 1 and 2 if a second stream option is
installed (see also Mode Internal, p. 23).
Mode External: In this mode, the AMI Silica is controlled by the
Sample Sequencer or by the second sample stream option if in-
stalled (see also Mode External, p. 23).
Mode Fieldbus: The AMI Silica is controlled via fieldbus.

Program List and Explanations
As control out- Signal outputs can be used for driving control units. We distinguish
put different kinds of controls:
P-controller: The controller action is proportional to the devi-
ation from the setpoint. The controller is characterized by
the P-Band. In the steady-state, the setpoint will never be
reached. The deviation is called steady-state error.
Parameters: setpoint, P-Band
PI-controller: The combination of a P-controller with an
I-controller will minimize the steady-state error. If the reset
time is set to zero, the I-controller is switched off.
Parameters: setpoint, P-Band, reset time.
PD-controller: The combination of a P-controller with a
D-controller will minimize the response time to a fast change
of the process value. If the derivative time is set to zero, the
D-controller is switched off.
Parameters: setpoint, P-Band, derivative time.
PID-controller: The combination of a P-, an I - and a D-con-
troller allows a proper control of the process.
Parameters: setpoint, P-Band, reset time, derivative time.
