Turbimax CUS52D Basic safety instructions
Endress+Hauser 5
2 Basic safety instructions
2.1 Requirements for personnel
• Installation, commissioning, operation and maintenance of the measuring system may
be carried out only by specially trained technical personnel.
• The technical personnel must be authorized by the plant operator to carry out the
specified activities.
• The electrical connection may be performed only by an electrical technician.
• The technical personnel must have read and understood these Operating Instructions
and must follow the instructions contained therein.
• Faults at the measuring point may only be rectified by authorized and specially trained
personnel.
Repairs not described in the Operating Instructions provided must be carried out only
directly at the manufacturer's site or by the service organization.
2.2 Designated use
CUS52D is a sensor for measuring turbidity and low solids content in drinking water and
process water applications.
The sensor is particularly suited for use in the following applications:
• Final turbidity measurement in outlet of waterworks
• Turbidity measurement in inlet of waterworks
• Turbidity measurement at all process stages
• Turbidity measurement for filter monitoring and filter backwashing
• Turbidity measurement in drinking water networks
• Turbidity measurement in media with high salinity (plastic sensor only)
Use of the device for any purpose other than that described, poses a threat to the safety of
people and of the entire measuring system and is therefore not permitted.
The manufacturer is not liable for damage caused by improper or non-designated use.
2.3 Workplace safety
As the user, you are responsible for complying with the following safety conditions:
• Installation guidelines
• Local standards and regulations
Electromagnetic compatibility
• The product has been tested for electromagnetic compatibility in accordance with the
applicable international standards for industrial applications.
• The electromagnetic compatibility indicated applies only to a product that has been
connected in accordance with these Operating Instructions.

2.4 Operational safety
Before commissioning the entire measuring point:
1. Verify that all connections are correct.
2. Ensure that electrical cables and hose connections are undamaged.
3. Do not operate damaged products, and protect them against unintentional operation.
4. Label damaged products as defective.
During operation:
‣If faults cannot be rectified:
products must be taken out of service and protected against unintentional operation.
2.5 Product safety
2.5.1 State-of-the-art technology
The product is designed to meet state-of-the-art safety requirements, has been tested, and
left the factory in a condition in which it is safe to operate. The relevant regulations and
international standards have been observed.

Turbimax CUS52D Product description
Endress+Hauser 7
3 Product description
3.1 Product design
The sensor with the 40 mm (1.57 in) diameter can be operated directly and completely in
the process without the need for further sampling (in-situ).
The sensor includes all necessary modules:
• Power supply
• Light sources
• Detectors
Detectors record the measuring signals, digitize them and process them into a measured
value.
• Sensor microcontroller
This is responsible for controlling internal processes and transmitting data.
All data - including the calibration data - are stored in the sensor. The sensor can be
precalibrated and used at a measuring point, calibrated externally, or used for several
measuring points with different calibrations.

3.1.1 Measuring principle
The sensor works using the 90° light scattering principle in accordance with ISO 7027 and
meets all the requirements of this standard (no divergence and a maximum convergence
of 1.5°). The ISO 7027 standard is obligatory for turbidity measurements in the drinking
water sector.
