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.

3. Installation
3.1. Installation Check List
Check Instrument’s specification must conform to the National Electrical
Code, all state and local codes, and all plant codes and standards
for electrical equipment.
On-site requirements
Installation Mount the instrument in vertical position.
Electrical Wiring Do not switch on the Instrument until all electrical connections are
If ordered:

100– 240 VAC ( 10%), 50/60 Hz ( 5%) or 24 VDC (±10%),
isolated power outlet with ground connection and 30 VA.
Sample line with min. 10 l/h and 0.15 – 2 bar.
Waste line with atmospheric drain.
Display should be at eye-level.
Mount the filter, filter vessel, and constant head cover. Connect the
sample and waste line. See Connecting Sample and Waste, p. 19
made.
Connect all external devices like limit switches, current loops and
pumps.
Connect power cord.
See Electrical Connections, p. 26.
See Install the Option pH, p. 22.
Insert the suction lances.
Close the occlusion frames of the peristaltic pump
Turn on the sample flow and wait until the flow cell is completely
filled
Switch on power.
Start <Fill system> see 4.4., 38
Program all parameters for external devices (interface, recorders,
etc.). Program all parameters for instrument operation (limits,
alarms, measuring interval).
If ordered: Calibrate pH sensor. See Standard pH, p. 53

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.
