Section 1 Specifications Microprocessor-controlled turbidity bypass sensor ULTRATURB sc for Components very low to medium turbidities with comprehensive self-diagnostics Measuring technique 90° infrared pulse scattered light technique in accordance with DIN EN ISO 7027 0.0001–1000 FNU (TE/F, NTU, FTU) can be programmed as required Measuring range (0.0001–250 EBC = 2500 ppm SiO2)
Section 2 General information 2.1 Safety information Please read this entire manual before unpacking, setting up or operating this equipment. Pay attention to all danger and caution statements. Failure to do so could result in serious injury to the operator or damage to the equipment. To ensure that the protection provided by this equipment is not impaired, do not use or install this equipment in any manner other than that specified in this manual.
90°. The low acquisition limit for this method makes it possible to even reliably differentiate turbidity particles in distilled water. This technique is defined in DIN EN ISO 7027. ULTRATURB sc sensors are designed in accordance with the requirements in this standard.
General information 2.5 Items supplied • ULTRATURB sc sensor • Connecting cable (length as per order) • User Manual • Factory test certificate • Accessory set LZP816 • Wiper set (for 4 changes) LZV275 (only plus and seawater version) 2.6 Function check After unpacking, all components should be checked for any transport damage and a short function check performed prior to installation.
Section 3 Installation DANGER Installation may only be carried out by qualified experts in accordance with all local safety regulations. 3.1 Assembling Select an appropriate installation location for the instrument to guarantee • safe installation • safe operation • problem-free maintenance Plan how to lay cables and hoses and their path in advance.
Installation 3.1.1 Connectors Important Note: The instrument can be damaged if the connectors and/or the union nuts are attached too tightly. Only hand-tighten the union nuts for the hose mounts. If necessary, hold the connectors with a tool (SW 22). The measuring instrument can be integrated into the measurement and analysis process using tubing (ID 13 mm) or a fixed connection (PVC system component pipework, compatible with 1"...
Installation 3.3 Connecting sensor cable CAUTION Always lay cables and hoses so that they do not pose a tripping risk. 1. Unscrew the protective caps from the controller socket and the cable plug and retain them. 2. Pay attention to the guide in the plug and slide the plug into the socket. 3.
Section 4 Operation 4.1 Operating the sc controller The sensor can be operated with all sc controllers. Prior to using the sensor, familiarise yourself with the principle of operation of your controller. Learn how to navigate in the menus and run appropriate functions. 4.2 Sensor setup When you connect the sensor for the first time, the serial number of the sensor is displayed as the sensor name.

Section 5 Maintenance It has been possible to reduce the scope of the maintenance to be performed by the user to only a few actions. Clearly summarised in a table and described in detail in the following sections, these actions can be quickly and straightforwardly performed by qualified personnel.
Maintenance 9. Remove the screw top and the sealing plug for the measuring chamber and accept OPEN MEAS. CHAMBER. 10. Remove the wiper holder and accept REMOVE WIPER HOLDER (only for plus and for seawater version). 11. Clean the measuring chamber and accept CLN. MEAS CHAMB. 12.
Maintenance 5.4 Replacing desiccant The ULTRATURB sc turbidity sensor is continuously subject to a wet environment. To provide protection against the moisture, there are 2 generously sized desiccant bags close to the optical and electronic components. To maintain this protection, the manufacturer recommends replacement or regeneration every 2 years.
Maintenance 5.5 Monitoring test equipment As part of a quality assurance system for test equipment monitoring, it is necessary to check the instrument calibration; this can be performed using a formazine standard series in accordance with DIN EN ISO 7027. You can either make up the formazine solution yourself as per the instructions that follow 5.5.1 Preparing formazine solution in accordance with DIN EN ISO 7027...

Maintenance The turbidity of this parent solution is 400, stated in Formazine Attenuation Units (FAU) or Formazine Nephelometric Units (FNU). This solution can be stored in a dark place at 25 °C (±3 °C) (77 °F (± 5.4 °F)) for around 4 weeks. Formazine reference solution Dilute the parent solution with the aid of pipettes and measuring flasks to produce reference solutions in the required range.
