2. Product Description
2.1. Description of the System
Application The AMI SAC254 is a complete monitoring system for the continu-
ous measurement of UV absorption at 254 nm for organic carbon
trending in potable water and waste water effluent.
It includes an optional turbidity correction according to DIN EN
38404-3.
Signal
Outputs
Two signal outputs programmable for measured values (freely scal-
able, linear, bilinear, log) 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).
Relays 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
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 in-
strument faults.
Input One input for potential-free contact to freeze the measuring value or
to interrupt control in automated installations (hold function or re-
mote-off).
Communica-
tion interface
(optional)
third signal output
a Profibus or Modbus connection
a HART connection
a USB Interface
Safety
Features
No data loss after power failure. All data is saved in non-volatile
memory. Overvoltage protection of in- and outputs.
Galvanic separation of measuring inputs and signal outputs.

Measuring
Principle
The AMI SAC254 is equipped with a two-wavelength photometer
with one optical channel. The light beam [F] irradiates the cuvette [E]
through the quartz window [I] from bottom to top.
The sample enters the cuvette [E] and the pressure tube [D] from the
bottom. The water level in the cuvette is calculated from the pressure
difference inside and outside the pressure tube [D].
During a filling cycle, the transmitted light intensity is continuously
measured as a function of the filling height. From the evaluation of
this logged curve results the Spectral Absorption Coefficient SAC.
When the cuvette is completely filled, it is emptied automatically
through a siphon tube.
Fouling
compensation
Due to measuring at multiple water levels, the measurement does
not depend on the initial intensity I0 of the light source. Instead, only
the change of absorption in relation to the changing water level is
taken into account. This makes the instrument insensitive to fouling
and aging of optical components.

operation
If the optional flow controller is installed, the sample enters at sample
inlet [F], flows through the inlet strainer [G], the pressure reducing
valve [E] and the capillary tube [D]. Otherwise, the sample enters di-
rectly at sample inlet [K].
From there, the sample flows into the
siphon tube [P],
pressure tube [C] and
cuvette [B].
The water level in the cuvette is calculated from the pressure differ-
ence inside and outside the pressure tube.
The measurement of UV absorption takes place while the cuvette is
being filled. During this time, the change of absorption in relation to
the raising water level is measured. Shortly before the upper end of
the cuvette is reached, the instrument is automatically emptied
through the siphon tube and a new filling cycle begins.
The instrument is emptied via the magnetic valve [I] when
there is no sample flow,
during calibration, verification or grab sample measurement,
when selecting the <Empty system> menu item.
Grab sample Grab sample functionality for manual measurement, verification and
calibration.
See Grab Sample, p. 37.
Calibration Correlation of the UV absorbance to organic carbon related parame-
ters (DOC, TOC, BOD, etc.) via one-point or two-point calibration or
manual configuration of the correlation parameters.
If necessary, a calibration of the absorbance measurement is also
possible, e.g. to adjust the values measured by the AMI SAC254 rel-
ative to a reference instrument.
See Calibration, p. 41.
Verification Certified standard solution available for instrument verification.
See Verification, p. 45.
Flow
controller
Optional accessory to protect the instrument from occasional parti-
cles and to adjust the flow rate. The option consists of inlet strainer
[G], pressure reducing valve [E] and capillary tube [D].
Cleaning
Module-II
Optional module for automatic chemical cleaning.

3.2. Mounting of Instrument Panel
The first part of this chapter describes the preparing and placing of
the system for use.
The instrument must only be installed by trained personnel.
Exactly align the instrument in vertical and horizontal position.
For ease of operation mount it so that the display is at eye
level.
For the installation a kit containing the following installation ma-
terial is available:
– 6 Screws 6x60 mm
– 6 Dowels
– 6 Washers 6.4/12 mm
Mounting re-
quirements
The instrument is only intended for indoor installation.
The location has to be free from vibrations and shocks.

3.5. Electrical Connections
WARNING
Risk of electrical shock.
Do not perform any work on electrical components if the transmit-
ter is switched on. Failure to follow safety instructions could result
in serious injury or death.
Always turn off power before manipulating electric parts.
Grounding requirements: Only operate the instrument from an
power outlet which has a ground connection.
Make sure the power specification of the instrument corre-
sponds to the power on site.
