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.

Make sure 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.

2.1.1 Use of Hazard Information

DANGER

Indicates a potentially or imminently hazardous situation which, if not avoided, will result in death or serious injury.

CAUTION Indicates a potentially hazardous situation that may result in minor or moderate injury.

Important Note: Information that requires special emphasis.

Note: Information that supplements points in the main text.

2.1.2 Precautionary Labels

Read all labels and tags attached to the instrument. Personal injury or damage to the instrument could occur if not observed

This symbol, if noted on the instrument, references the instruction manual for operation and/or safety information.

This symbol indicates that a risk of electrical shock and/or electrocution exists.

Electrical equipment marked with this symbol may not be disposed of in European public disposal systems after 12 August of 2005. In conformity with European local and national regulations (EU Directive 2002/96/EC), European electrical equipment users must now return old or end-of life equipment to the Producer for disposal at no charge to the user.

Note: For return for recycling, please contact the equipment producer or supplier for instructions on how to return end-of-life equipment, producer-supplied electrical accessories, and all auxiliary items for proper disposal.

ts-line: 0.001–4000 FNU/NTU; 0.001 mg/L–50.0 g/L

High-precision turbidity and solids probe made of stainless steel or plastic for color-independent measurement of fine turbidities and sludges.

hs-line: 0.001–4000 FNU/NTU; 0.001 mg/L–500.0 g/L

High-precision turbidity and solids probe made of stainless steel or plastic for color-independent measurement of highly concentrated sludges.

inline: 0.001–4000 FNU/NTU; 0.001 mg/L–50.0 g/L

High-precision pipe installation probe for turbidity and solids made of stainless steel for color-independent measurement of fine turbidities and sludges.

highline: 0.001–4000 FNU/NTU; 0.001 mg/L–500.0 g/L

High-precision pipe installation probe for turbidity and suspended solids made of stainless steel for color-independent measurement of highly concentrated sludges.

2.3 Measuring Principle

The measuring principle is based on a combined infrared absorption scattered light technique that measures the lowest turbidity values in accordance with DIN EN 27027 just as precisely and continuously as high sludge content. Using this method, the light scattered sideways by the turbidity particles is measured over an angle of 90°.

2.4 Handling

The sensor contains high-quality optical and electronic assemblies. Make sure the sensor is not subjected to any hard mechanical knocks. There are no customer-serviceable items inside the sensor.

3.1.1 Function Check

After unpacking, both components should be checked for any transport damage and a short function check performed prior to installation.

To perform a function check, connect the sensor to the display unit and power the unit. Shortly after the unit is plugged in, the display is activated and the instrument switches to the measurement display. Measured values taken in air is meaningless.

If no messages appear in the lower part of the display, the function check is then complete.
