Legal
Requirements
The user is responsible for proper system operation.
All precautions must be followed to ensure safe operation
of the instrument.
Spare Parts
and
Disposables
Use only official SWAN spare parts and disposables. If other parts
are used during the normal warranty period, the manufacturer’s
warranty is voided.
Modifications Modifications and instrument upgrades shall only be carried out by
an authorized Service Technician. SWAN will not accept responsi-
bility for any claim resulting from unauthorized modification or alter-
ation.
WARNING
Risk of Electrical Shock
If proper operation is no longer possible, the instrument must be
disconnected from all power lines, and measures must be taken
to prevent inadvertent operation.
To prevent from electrical shock, always make sure that the
ground wire is connected.
Service shall be performed by authorized personnel only.

Safety Instructions
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.
For safe handling of the reagents you must read and under-
stand the instructions in this manual, as well as the Material
Safety Data Sheets (MSDS)

2. Product Description
Application
Range
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 in-
hibitors, 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
Disinfectant
Measurement
Signal
Outputs
Two signal outputs programmable for measured values (freely
scaleable, linear or bilinear) or as continuous control output (control
parameters programmable).
Current loop: 0/420 mA
Maximal burden: 510
Third signal output available as an option. The third signal output
can be operated as a current source or as a current sink (selectable
via switch).

pH Optional pH measurement is possible (pH correction or calibration).
Relay Box The AMI Relay Box is designed for the direct power supply and ac-
tivation of dosing devices which are controlled with an AMI trans-
mitter, e. g. to connect two solenoid valves or one motor valve for
disinfectant addition.

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 re-
agents [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.

have been completed.
Connect all external devices like limit switches, current loops and
pumps.
Connect power cord.
See Electrical Connections, p. 24

3.2. Mounting of Instrument Panel
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
Mounting re-
quirements
The instrument is only intended for indoor installation.
For dimensions see Dimensions, p. 14.
3.3. Connecting Sample and Waste
3.3.1 FEP Tube at Sample Inlet
Use plastic tube (FEP, PA, or PE 6 x 8 mm) to connect the sample
line.
Mounting of
SERTO fitting
Process
calibration
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 mea-
surement.
