1.3. Restrictions for use
The sample must not contain any particles, which may block the
flow cell. Sufficient sample flow is coercive for the correct function
of the instrument.
If the sample contains only little disinfectant concentrations, or
there is the danger of biological growth, we recommend to use the
optional Cleaning module from Swan.
WARNING
Health hazard
Some reagents are etching and can cause severe burns or eye
damage.

Disinfectant
Measurement
The AMI Codes-II analyzer is a complete monitoring system for the
automatic, continuous measurement and dosing control of chlorine
and other disinfectants based on the DPD colorimetric method
AWWA 4500 Cl-G and on EN ISO 7393-2.
It can be used for measuring disinfectants in:
Potable water
Swimming pools
Cooling water
Effluent
Seawater
It is also applicable for water containing additives like corrosion inhibitors, cyanuric acids and antiscalants.
For the determination of free chlorine, chlorine dioxide, bromine
and iodine the reagents:
Oxycon on-line DPD
Oxycon on-line Buffer
are needed.
The measurement of monochloramine or ozone requires an addi-
tional reagent:
Oxycon on-line KI; which is added to Oxycon on-line Buffer

Product Description
Fluidics The sample flows through the sample inlet [F] and the filter vessel
[G] into the constant head [A]. Adjust the flow regulating valve [D]
so that always a small part of the sample flows through the overflow
tube [B] into the drain [H]. A part of the sample flows through the
photometer inlet [C] into the mixing chamber [E], where the reagents [J] and [K] are added by the peristaltic pump [O] and mixed
with the sample. The mixed sample flows through the photometer
[N] and disinfectant is measured. If KI and Buffer are mixed in the
reagent canister [K] monochloramine is measured.
After the measurement the sample flows through the outlet of the
photometer where it will be aerated through air inlet [P] to generate
bubbles. Then the sample flows through the bubble detector [M]
into the photometer drain [I].

Time
interval of a
measurement
The measuring interval can be set between 1 and 12 minutes. The
time sequence of a measurement with a measuring interval of
5 min is shown in the diagram below.
The blue bar represents the sample which flows continuously
through the photometer. A short time before the measurement
starts, a zero point measurement is performed. Then the peristaltic
pump starts and a small portion of the reagents [J] and [K] is
pumped into the mixing chamber. Shortly after, if the mixture is in
the photometer, the sample is measured.

3.3. Connecting Sample and Waste
Make 3 manual measurements. Use a high quality photometer,
e.g. Chematest from Swan. Calculate average value and compare
this value to the value indicated by the AMI. If necessary, correct
the value. The zero point is done automatically before each measurement.
The first part of this chapter describes the preparing and placing of
the system for use.
The instrument must only be installed by trained personnel.
Mount the instrument in vertical position.
For ease of operation mount it so that the display is at eye
level.
For the installation a kit containing the following installation
material is available:
– 6 Screws 6x60 mm
–6 Dowels
– 6 Washers 6.4/12 mm
The instrument is only intended for indoor installation.

CAUTION
Risk of damage of the relays in the AMI Transmitter due to

after refilling the reagent canisters,
before a system shut-down to flush the system with deminer-
alized water until no more reagent is left in the system.
Navigate to menu< Maintenance /
Service/ Fill system>.
Press [Enter].

etc.)
Program all parameters for instrument operation (disinfectant, lim-

See Standard pH, p. 52.
2 Perform process calibration.
See Process Calibration of DIS, p. 50
If ordered:
Calibration of
pH sensor
Process DIS Let the instrument run for 1 h.
The instrument should be operating for 1h before performing a pH
calibration.
Program the two buffers you want to use for calibration (Installation/
Sensors/Standards). Calibrate the pH sensor with two buffers, e.g.
pH 7.00 and pH 9.00. See chapter Calibration, p. 50 for details.
Use CHEMATEST 25 (or equivalent photometer) to determine the
sample disinfectant concentration. Take the sample directly from
the flow cell. Determine the sample disinfectant value by 3 manual
DPD measurements. Calculate the average value. Compare this
value to the value, indicated by the AMI.
Keep in mind the accuracy of your manual measurement. Only correct the instrument if the difference is significant.
Perform process DIS if necessary. See chapter Calibration, p. 50
for details.

Basically follow the dialog in menu 3.2.1
<Maintenance>\<Service>\<Verification>.
NOTICE: Start any time, if a measuring cycle is in progress wait
for next prompt.
1 Stop sample flow by closing regulating valve. Wait for next
prompt: Constant head will be drained and an automatic zero
will be defined.
2 Open cuvette of the photometer and insert the verification filter.
[Enter] to continue.
3 Align the triangle shape either to the front– or backside and ad-
just for minimal absorbance (see AMI Display).
4 Press [Enter] to save the verification measurement. The verifi-
cation is successful if the difference is within the limits. [Enter] to
continue.

6.10. Tube Replacement
6.10.1 Replace the Pump Tubes
The pump tube [D] of the peristaltic pump is exposed to a minimal
wear.
It is therefore recommended to exchange the pump tube annually.
CAUTION
Pollution of reagents possible.
If the occlusion frames are opened during operation, already
mixed reagents will flow back into the reagent canisters and pollute the reagents.
Never open the occlusion frames if the instrument is in opera-
tion.
Proceed according to Stop of Operation for Maintenance, p.
43 before opening the occlusion frames.

Program List and Explanations
As control
output
Signal outputs can be used for driving control units. We distinguish
different kinds of controls:
P-controller: The controller action is proportional to the devia-
tion 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.

5.2.1.43.13 Setpoint: 0–600 B/s
5.2.1.43.23 P-Band: 0 –200 B/s
Reset time: The reset time is the time till the step response of a
single I-controller will reach the same value as it will be suddenly
reached by a P-controller.
Range: 0–9’000 sec
Derivative time: The derivative time is the time till the ramp
response of a single P-controller will reach the same value as it will
be suddenly reached by a D-controller.
Range: 0–9’000 sec
Control timeout: If a controller action (dosing intensity) is constantly
over 90% during a defined period of time and the process value
does not come closer to the setpoint, the dosing process will be
stopped for safety reasons.
Range: 0–720 min
