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.

AMI Phosphate-II

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

AMI Phosphate-II

Product Description

A-96.250.641 / 290312 9

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.

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:

1 A zero measurement with the sample is performed before the

reagents are added.

2 The 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].

3 The solenoid valve [I] will be activated to close the inlet of the

photometer.

4 The sample remains in the photometer for 7 minutes. During

this time a reaction with the reagents takes place.

5 After the 7 min have elapsed a second measurement is carried

out and the o-phosphate concentration is calculated.

6 If the measurement has been finished, the solenoid valve will be

deactivated to open the inlet of the photometer.

7 The sample flows through the outlet of the photometer where it

will be aerated to generate bubbles.

8 The 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.
