1.2. General Safety Regulations
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 war-
ranty is voided.
Modifications Modifications and instrument upgrades shall only be carried out by
an authorized Service Technician. SWAN will not accept responsibili-
ty for any claim resulting from unauthorized modification or alter-
ation.
WARNING
Electrical Shock Hazard
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.
Whenever electronic service is required, disconnect instrument
power and power of devices connected to.

– relay 2,
– alarm relay
WARNING
For safe instrument installation and operation you must read and
understand the instructions in this manual.
WARNING
Only SWAN trained and authorized personnel shall perform the
tasks described in this document.

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 CC is a complete monitoring system for the auto-
matic, 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 inhib-
itors, cyanuric acid and antiscaleants.
Determines free available chlorine, total chlorine and calculates
monochloramine, dichloramine and combined chlorine.
Necessary reagents:
Oxycon on-line DPD
Oxycon on-line Buffer
Oxycon on-line KI
Disinfectant
Measurement
Signal
Outputs
Two signal outputs programmable for measured values (freely scale-
able, linear or bilinear) or as continuous control output (control pa-
rameters programmable).
Current loop: 0/4–20 mA
Maximal burden: 510 Ω
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).
Relay Two potential-free contacts programmable as limit switches for mea-
suring values, controllers or timer for system cleaning with automatic
hold function. Both contacts can be used as normally open or nor-
mally closed.
Maximum load: 1 A/250 VAC

Fluidics The sample flows through the sample inlet [R] and the inlet filter [H]
into the constant head [A]. Adjust the flow regulating valve [F] so that
always a small part of the sample flows through the overflow tube [B]
into the constant head drain [Q].
Free available
chlorine
A part of the sample flows through the photometer inlet [C] into the
mixing chamber [E], where the reagents [M] and [N] are added by the
peristaltic pump [D] and mixed with the sample. The mixed sample
flows through the photometer [K] where the free available chlorine is
measured.

Total chlorine 1 After the measurement of free available chlorine is finished the sole-
noid valve [G] is energized for a short time and reagent [O] is added
to determine total chlorine 1.
Total chlorine 2 To ensure the necessary reaction time of 2 min. for the determination
of total chlorine 2, the sample flow is stopped by the solenoid valve
[J]. After the time has elapsed, total chlorine is measured and sole-
noid valve [J] 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 [L] into
the photometer drain [P].

General Two different types of measurements are distinguished:
Free available chlorine (fac) measurement
Overall measurement including free available chlorine (fac), to-
tal chlorine 1 (tc1) and total chlorine 2 (tc2).
The Interval fac and the Interval tc2 can be set individually:
Interval fac between 0 and 12 min.
Interval tc2 between 0 and 60 min (overall measurement).
Note: If the fac interval is set to zero, it is nevertheless measured
in the overall measurement.
The default setting for fac measurement interval is 5 min and for
overall measurement interval 20 min.
Time
sequence of an
overall
measurement
The blue bar represents the sample flow through the photometer. At
the beginning the solenoid valve [J] is de-energized and the sample
flows 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 “Oxycon on-line
DPD” and “OXYCON ON-LINE Buffer” is pumped into the mixing
chamber. During this time, the solenoid valve [G] is de-energized
and the “Oxycon On-line KI” circulates between the peristaltic pump
and the valve block.
A short time after, if the mixture is in the photometer, the free avail-
able chlorine (fac) of the sample is measured.
After about 25 sec the peristaltic pump starts again. Now the sole-
noid valve [G] is energized and a small portion of the reagents “Oxy-
con on-line DPD”, “OXYCON ON-LINE Buffer” and “Oxycon On-line
KI” is pumped into the mixing chamber.
A short time after, the solenoid valve [J] is energized and the sample
flow through the potometer is stopped. Immediately after that, the tc
1 is measured.
The “calculated monochloramine” (cmc) is calculated and displayed.
After about 120 sec the tc 2 is measured and then the “calculated di-
chloramine” (cdc) and the “calculated combined chlorine” (ccc) are
calculated and displayed. After the measurement is finished, the so-
lenoid valve [J] is de-energized and sample flows through the pho-
tometer and a flush time of 2 minutes follows.

The programmed measuring intervals of tc2 [F] and fac [G] may
overlap each other.
The tc2 measurement has priority and therefore always takes place
in the programed measuring interval [F]. The fac measurement is
filled in the gaps [H] of the overall measurement and may be shifted
(orange arrow) in respect to programmed interval. If 2 fac measure-
ments are programmed during a overall measurement one of them is
cancelled (red arrow).
