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 which is available as an op-
tion for the AMI Phosphate-II.
WARNING
For safe instrument installation and operation you must read
and understand the instructions in this manual, as well as the
Material Safety Data Sheets (MSDS)
Oxycon On-line Phosphate 1
Oxycon On-line Phosphate 2
ATTENTION
Never loosen pump tubes when flow is on. Otherwise you pol-
lute the reagents.

Product Description
2. Product Description
Application This manual describes the functions of the analyzers:
AMI Phosphate-II
AMI Phosphate-II B
Both analyzers are complete monitoring systems for the automatic
continuous measurement of ortho-Phosphate. ortho-Phosphate
can be found in many applications like corrosion protection in sani-
tary systems and boilers or as additive to detergents. On-line mea-
surement is used in quality control of drinking water, waste water
plants and thermal power plants.
Measuring
principle
The measurement is based on the molybdenum blue colorimetric
method according to APHA 4500-P E. and on EN ISO 6878. When
the reaction product of o-phosphate with ammonium-molybdate is
reduced with ascorbic acid, the intensely colored molybdenum blue
is formed. The color intensity is proportional to the o-phosphate
concentration of the sample and is measured photometrically at
815 nm.
Programmable
Measuring
Intervals
The duration of a measuring interval can be set to:
10 min (not available if “2 Channels” is selected)
15 min
20 min
30 min
Independent of the programmed measuring interval, the measure-
ment time of a sample takes 7 minutes.
Signal
Outputs
Two signal outputs programmable for measured values (freely scal-
able, linear or bilinear) or as continuous control output (control pa-
rameters programmable).
Current loop: 0/4–20 mA
Maximal burden: 510 
Third signal output with the same specifications as option.
(Only possible if no communication interface is used.)
Relay Two potential-free contact programmable as limit switches for mea-
suring values, controllers or timer for system cleaning with auto-
matic hold function.
Maximum load: 1 A/250 VAC

Alarm Relay One potential free contact.
Alternatively:
Open during normal operation, closed on error and loss of
power.
Closed during normal operation, open on error and loss of
power.
Summary alarm indication for programmable alarm values
and instrument faults.
Input One potential-free contact to freeze the measuring value or to inter-
rupt control in automated installations (hold function or remote-off).
The potential-free contact is located:
at the AMI Phosphate-II in the AMI Transmitter
at the AMI Phosphate-II B in the peristaltic pump
Safety
Features
No data loss after power failure. All data is saved in non-volatile
memory. Over voltage protection of in- and outputs.Galvanic sepa-
ration of measuring inputs and signal outputs.The analyzer is facto-
ry tested and ready for installation and operation.
Communica-
tion Interface
(optional)
RS232 for logger download with HyperTerminal or RS485 with
Fieldbus protocol Modbus or Profibus DP. Webserver connection
via Modbus.
2nd Sample
Stream
AMI Phosphate-II B
As an option an inlet for two sample streams with a sample switch-
ing valve can be installed onto the panel of the AMI Phosphate-II B
Cleaning
Module
AMI Phosphate-II
As an option a cleaning module is available which can be connect-
ed to the AMI Phosphate-II.
WARNING
The drain of the photometer outlet contains Hexammonium
heptamolybdate 4-hydrate.
At no means recirculate it into the water system.

10 A-96.250.641 / 290312
AMI Phosphate-II
Product Description
On-line
operation
The sample flows through the sample inlet [K] and the filter vessel
[J] into the constant head [A]. Adjust the flow regulating valve so
that always a small part of the sample flows through the overflow
tube [B] into the drain [R]. This adjustment ensures a sufficient
sample flow through the measuring chamber of the photometer [M].
If no measurement takes place, the sample flows through the outlet
of the photometer where it will be aerated through air inlet [H] to
generate bubbles. Then the sample flows through the bubble coun-
ter [P] into the waste [Q].
If a measuring cycle starts:
1A zero measurement with the sample is performed before the
reagents are added.
2The peristaltic pump [C] pumps the reagents [N] and [O] into the
mixing chamber [G] where they are mixed together with the
sample and then flowing through the photometer [M].
3The solenoid valve [I] will be activated to close the inlet of the
photometer.
4The sample remains in the photometer for 7 minutes. During
this time a reaction with the reagents takes place.
5After the 7 min have elapsed a second measurement is carried
out and the o-phosphate concentration is calculated.
6If the measurement has been finished, the solenoid valve will be
deactivated to open the inlet of the photometer.
7The sample flows through the outlet of the photometer where it
will be aerated to generate bubbles.
8The sample flows through the bubble detector [P] and into the
waste [Q].
Calibration Close the flow regulating valve to drain the constant head. Prepare
a standard solution with deionized water and fill it into the constant
head. A normal measuring cycle is then initialized, the measured
value is used to calculate the photometer's slope. For details see
Calibration, S. 44.
