To prevent injuries and product damage, observe the following:
▶Install the product according to the regulations applicable in the respective country.
▶Make sure only trained technicians carry out installation and maintenance work.
▶Secure the product or system to prevent unintentional activation.
▶Do not subject the product to mechanical stress.
▶The SAC254 Sensor is made from stainless steel. Sensors made from stainless steel must be cleaned
immediately after coming into contact with salt water or other corrosive substances (e.g acids, alkalis,
chlorine-based connections).
▶The material resistance must be checked after every use.
▶The sensor has seals made from NBR (nitrile butadiene rubber). Sealing rings made from other materials
may be used upon individual request. Before operation, ensure that the measured medium does not
damage the seals.
▶Do not cut, damage or change the cord. Make sure there are no heavy objects on the cable and that the
cable is not folded. Make sure that the cable is not anywhere near hot surfaces.
▶If the sensor cable is damaged, then it must be replaced with an original part by the Bürkert Customer
Service.
▶Do not place unsuitable items in the optical path as long as the measurement process is running, as this
can cause damage to the sensor or incorrect measurement results.
▶Stop operation of the sensor in the event of excessive heat development (i.e. if it is hot to the touch).
Switch off the sensor immediately and unplug the power cord from the power supply. Please contact
your dealer or the Bürkert Customer Service.
▶After an interruption in the power supply, make sure that the process is restarted in a controlled manner.
▶Never try to disassemble or modify the product or a part of the product if such a procedure is not expli-
citly described in this manual.
▶Products from Bürkert meet the highest safety standards. Inspections, modifications and repairs to the
product, which involve the replacement of the connecting cable, must be carried out by Bürkert or by a
workshop /qualified experts authorized by Bürkert. Defective, improper repairs can lead to accidents

The colour of the product status indicator gives the following pieces of information:
▪Whether product diagnostics are active or not. Diagnostics are active on the product and cannot be de-
activated.
▪If product diagnostics are active, then the product status indicator shows whether diagnostics events
have been generated or not. If several diagnostics events have been generated, then the product status
indicator shows the diagnostics event with the highest priority. Refer to table [}15]
If the product status indicator flashes, then the product is selected in a man-machine interface such as the
Bürkert Communicator software.

3.4 Memory Card
A micro SD card (available as an optional accessory) can be used as a memory card to store product-spe-
cific values and user settings and transfer them to another product. Refer to chapter Install the micro SD
card [}31] and Transfer data to or from another product [}32].
CAUTION!
The micro SD card used is a special industrial version that offers additional durability and temperature res-
istance.
▶Do not use a standard micro SD card for the product. Only purchase the micro SD card for the product
from your Bürkert sales department.
Function of the micro SD card limited to data exchange
The micro SD card is not suitable for back-ups. If the micro SD card of the product is re-inserted at
a later stage, then the data last saved are not restored. The function of the micro SD card is limited
to data exchange.
3.5 Operating principle
The ME63 Sensor Interface represents the central control unit for MS08 and MS09.
The ME63 Sensor Interface is an additional interface for büS devices. The ME63 Sensor Interface ex-
changes data with the SAC254 Sensor on Ethernet communication.
Measurement principle
For optimal use of the sensor, it is essential to understand the measuring principle and measurement setup
which the sensor is based on. The following is an overview of the measurement principle, the optical ar-
rangement and the subsequent calculation.

Type MS08
Product description

3 Optical path 4 Mirror
5 Lenses 6 Light sources
The SAC254 Sensor essentially consists of four parts (See figure above):
▪a defined light source that consists of two LEDs of different wavelengths
– wavelength LED 1: 254nm
– wavelength LED 2: 530nm (for turbidity correction)
▪a lens system
▪the optical path through the medium
▪a detector with ambient light suppression
Both LEDs are connected one after the other in a special profile. The light emitted by the LEDs passes
through the medium on the way to the detector and is partially weakened by the medium. The detector
picks up the remaining light and thus determines its intensity I. The weakening of the light when passing
through the measurement medium is compared to the weakening caused by ultra-pure water. The meas-
urement in ultra-pure water provides the so-called basic intensity I0. Using equation 1 and equation 2, the
SAC254 Sensor determines the transmission T and the absorbance A of both of the above-mentioned
wavelengths.
T = I

where:

Icurrent light intensity
I0basic light intensity in ultra-pure water
Aabsorption in AUs (AU = absorbance unit)
The light intensity of LEDs often varies with the temperature. Therefore, a temperature correction factor is
determined for each wavelength of the SAC254 Sensor and is used to calculate the measurement value.
Spectral Absorption Coefficient SAC
The SAC254 Sensor outputs the SAC of the wavelength of LED 1 at 254 nm (SAC254). Scattering of light on
particles in a solution is seen as turbidity by the observer. The SAC254 Sensor uses the absorbance of 530
nm (A530) for the turbidity correction of the absorption measurement of the wavelength emitted by LED 1
(A254). The SAC254 is calculated using the equation 3 In this equation, d is the optical path length in milli-
metres [mm]. Available path length for SAC254 Sensor: 50 mm.
