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.

Outputs
The AMI Codes-II TC is a complete monitoring system for the automatic, continuous measurement and dosing control of chlorine
based on the DPD colorimetric method APHA 4500 Cl-G and on
EN ISO 7393-2.
It can be used for measuring disinfectants in:
Pools and sanitary water
Cooling water
Waste water effluent
It is also applicable for water containing additives like corrosion inhibitors, cyanuric acid and antiscaleants.
Determines total chlorine (tc1 and tc2) and calculates dichloramine.
Necessary reagents:
Oxycon on-line DPD
Oxycon on-line Buffer
Oxycon on-line KI
Disinfectant Measuring range Accuracy
Total chlorine
(Standard Mode)
Total chlorine
(Extended Mode)
Two operating modes are available depending on the desired measuring range. Default mode “Standard” for concentrations up to 5
ppm. Select “Extended” for measurements up to 10 ppm which will
lead to higher reagent consumption.
Two signal outputs programmable for measured values (freely
scaleable, linear or bilinear) or as continuous control output (control
parameters programmable).
Current loop: 0/4– 20 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).

tion of total chlorine 2, the sample flow is stopped by the solenoid
valve [G]. After the time has elapsed, total chlorine 2 is measured
and the solenoid valve [G] opens again.
After the measurement the sample flows through the outlet of the
photometer where it will be aerated through air inlet [I] to generate
bubbles. Then the sample flows through the bubble detector [K]
into the photometer drain [N].

Product Description
Time
interval of a
measurement
The measuring interval can be set between 3 and 60 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 flowing sample. 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 [L]
and [M] is pumped into the mixing chamber.
A short time after, when the mixture is in the photometer, the solenoid valve [G] is energized and the sample flow through the potometer is stopped. Immediately after that, the total chlorine 1 is
measured. After 120 sec. the total chlorine 2 is measured. After the
measurement is finished, the solenoid valve [G] is de-energized
and sample flows through the photometer until the next measurement starts.

requirements
3.3. Connecting Sample and Waste
Make 3 manual measurements. Use a high quality photometer,
e.g. Chematest from Swan. Calculate the average value and compare this value with the measuring value of the AMI Monitor. 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 instrument 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.
For dimensions see Dimensions, p. 16.

CAUTION
Risk of damage of the relays in the AMI Transmitter due to
heavy inductive load.
Heavy inductive or directly controlled loads (solenoid valves,
dosing pumps) may destroy the relay contacts.

able as an option or suitable external power relays.

Actuators Actuators, like motor valves, are using both relays: One relay con-

If ordered:
Calibration of

Process DIS Let the instrument run for 1 h.
The instrument should be operating for 1h before performing a pH
calibration.
Use CHEMATEST (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. 51
for details.

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.

do this, proceed as follows:
1 Switch off the analyzer according to Stop of Operation for Main-
tenance, p. 45.
2 Remove the protection cap and all pump tubes as described in
Dismount pump tubes, p. 60.
3 Unscrew the 4 screws of the peristaltic pump housing and re-
move the cover.
4 Disconnect the motor connector [A].
A Motor connector
5 Feed the cable into the housing through one of the PG7 cable
glands.
6 Connect the cable to the terminal block of the peristaltic pump
according to Connection Diagram, p. 28
7 Reassemble in reverse order.

Troubleshooting
7.5. Replacing Fuses
WARNING
External Voltage.
External supplied devices connected to relay 1 or 2 or to the
alarm relay can cause electrical shocks.
Make sure that the devices connected to the following con-
tacts are disconnected from the power before resuming installation.
– relay 1
– relay 2
– alarm relay
When a fuse has blown, find out the cause and fix it before
replacing it with a new one.
Use tweezers or needle-nosed pliers to remove the defective fuse.
Use original fuses provided by SWAN only.

As control out-
Signal outputs can be used for driving control units. We distinguish
different kinds of controls:
put
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.
Ziegler-Nichols method for the optimization of a PID controller:
Parameters: Setpoint, P-Band, Reset time, Derivative time
