1.1 How to use this component operating manual
Structure of the
IQ SENSOR NET operating
manual
Fig. 1-1 Structure of the IQ SENSOR NET operating manual
The IQ SENSOR NET operating manual has a modular structure like the
IQ SENSOR NET itself. It consists of a system operating manual and the
operating manuals of all the components used.
Please file this component operating manual in the ring binder of the
system operating manual.

1.2 Field of application
The CarboVis 700/5 IQ Set is an online measuring system for in-situ
determination of carbon sum parameters in waste water treatment
plants. The range of application comprises control, feedback control
and monitoring. The CarboVis 700/5 IQ Set can be used in the inlet or
outlet.
Compressed-air
cleaning The CarboVis 700/5 IQ Set is equipped with a compressed-air
operated cleaning system for the sensor. It works effectively and
without side-effects. The cleaning system is maintenance free and
wear free.
1.3 Measuring principle of the UV/VIS sensor
The UV/VIS sensor operates according to the measuring principle of
UV/VIS spectrometry.
Any substance contained in a measuring solution weakens a light
beam that penetrates the measuring solution. The weakening
(absorbance) of the light beam is measured for different wavelengths.
The wavelength dependent distribution produces the absorbance
spectrum.
The wavelength range where an absorbance occurs characterizes the
substance. The amount of the substance determines the extent of the
absorbance.
The influence of typical interference matrix variants occurring at
municipal waste water treatment plants can be eliminated by including
the entire absorbance spectrum.
With this measuring principle, measuring does not take place
continuously but at intervals.

1.4 Structure of the UV/VIS sensor
A UV/VIS sensor contains a light source (1), a measuring gap (3) to
enable the contact of light with the measuring solution, and a detector
(5) to measure the alleviated light beam.
Thesenderoftheopticalsystem(2)directsa lightbeam,themeasuring
beam (6), through the measuring solution and a second light beam, the
reference beam (8), over a distance without measuring solution. The
test sample is between both measurement windows (3) in the
measuring gap.
The receiver of the optical system (4) directs the measuring beam and
reference beam to the detector. In the detector, the light is received by
fixed photo diodes.

a sensor in the IQ SENSOR NET.
The technical specifications according to chapter 8 TECHNICAL DATA
mustbeobserved.Only operationaccordingto the instructions givenin
this operating manual is considered to be authorized.
Any other use is considered to be unauthorized. Unauthorized use
invalidates any claims with regard to the guarantee.
Caution
Only operate the sensor together with the MIQ/VIS connection
module.
2.2 General safety instructions
The sensor left the factory in a safe and secure technical condition.
Function and
operational safety The failure-free function and operational safety of the sensor is only guaranteed if the generally applicable safety measures and the special
safety instructions in this operating manual are followed during its use.
The failure-free function and operational safety of the sensor is only
guaranteed under the environmental conditions that are specified in
chapter 8 TECHNICAL DATA.
The specified temperature (see chapter 8 TECHNICAL DATA) must be
