1 Safety instructions
1.1 Designated use
The Turbimax W CUS65 sensor is used for optical turbidity and solids content measurement. Due
to various sensor heads the sensor is suitable for use from low to high concentration ranges.
• Wastewater clarification / sludge treatment
• Boiler feedwater monitoring
• Condensate monitoring
•Servicewatermonitoring
Any other use than the one described here compromises the safety of persons and the entire
measuring system and is, therefore, not permitted.
The manufacturer is not liable for damage caused by improper or non-designated use.
1.2 Installation, commissioning and operation
Please note the following items:
• Installation, commissioning, operation and maintenance of the measuring system must only be
carried out by trained technical personnel.
The technical personnel must be authorized for the specified activities by the system operator.
• Electrical connection must only be carried out by a certified electrician.
• Technical personnel must have read and understood these Operating Instructions and must
adhere to them.
• Before commissioning the entire measuring point, check all the connections for
correctness. Ensure that electrical cables and hose connections are not damaged.
• Do not operate damaged products and secure them against unintentional
commissioning. Mark the damaged product as being defective.
• Measuring point faults may only be rectified by authorized and specially trained
personnel.
• If faults can not be rectified, the products must be taken out of service and secured against
unintentional commissioning.
• Repairs not described in these Operating Instructions may only be carried out at the
manufacturer’s or by the service organization.
1.3 Operational safety
The sensor has been designed and tested according to the state of the art and left the factory in
perfect functioning order.
Relevant regulations and European standards have been met.
As the user, you are responsible for complying with the following safety conditions:
• Installation instructions
• Local prevailing standards and regulations.

3.1 Incoming acceptance, transport, storage
• Make sure the packaging is undamaged!
Inform the supplier about damage to the packaging. Keep the damaged packaging until the matter
has been settled.
• Make sure the contents are undamaged!
Inform the supplier about damage to the delivery contents. Keep the damaged products until the
matter has been settled.
• Check that the scope of delivery is complete and agrees with your order and the shipping
documents.
• The packaging material used to store or to transport the product must provide shock protection
and humidity protection. The original packaging offers the best protection. Also, keep to the
approved ambient conditions (see "Technical data").
• If you have any questions, please contact your supplier or your sales center responsible.

3.2.2 Wall distance
Installing the sensor in pipework or very close to the wall can cause backscatter which results in a
higher sensor signal.
The effective wall or bottom distance can be optimized by aligning the flat sensor side.
!Note!
The following generally applies: The lower the turbidity to be measured, the darker the vessel walls
should be and the greater the wall distance should also be.
3.2.3 Pipe installation
The following figure illustrates various installation positions in pipes and indicates whether they are
permitted or not.

Fig. 3: Orientation and installation positions (with retractable assembly CUA451)
• The pipeline diameter must be at least 100 mm (4") if reflective materials (e.g. stainless steel) are
used.
• Install the sensor in places with uniform flow conditions.
• The best installation location is in the ascending pipe (it. 1). Installation is also possible in the
horizontal pipe (it. 5).
• Do not install the sensor in places where air may collect or foam bubbles form (it. 3) or where
suspended particles may settle (it. 2).
• Avoid installation in the down pipe (it. 4).
• Pay attention to the correct installation angle α(s. below).

3.2.4 Immersion operation
!Note!
• Observe the required mounting clearance for the installation mode selected. Installing the sensor
in pipes or close to a wall can lead to backscattering resulting in signal increase, mainly with
measurements in low turbidity ranges (<100 FNU).
• Make sure the sensor is completey immersed at changing water levels.

3.3 Installation instructions
3.3.1 Measuring system
A complete measuring system comprises:
• Turbidity transmitter CUM740
• Turbidity sensor Turbimax W CUS65
• Immersion pipe CYY105 or
• Retractable assembly Cleanfit CUA451
• Extension cable (optional)
• Junction box (optional)
3.3.2 Notes on installation
Proceed as follows for complete installation of a measuring point:
1. Install the retractable (if used) into the process.
2. Connect the water to the rinsing nozzles (if using assembly with cleaning).
3. Install and connect the turbidity sensor.
4. Install the immersion assembly (if used) into the process.
"Caution!
• Please follow national grounding regulations when using metal assemblies and installation
devices.
• The sensor must be installed in an immersion assembly for immersion operation. Do not use the
sensor suspended freely from the cable.
• Screw the sensor into the assembly in such a way that the cable does not become twisted.
• Avoid large traction (e.g. by tugging) on the cable.
!Note!
• Select a mounting location which can be easily accessed for later calibrations.
• When installing without an assembly, the sensor optics must be immersed at least 4 cm (1.5")
into the medium.
• Please pay special attention to the installation instructions in the Operating Instructions of the
assembly used.
