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 the equipment is not impaired, do not use or
install this equipment in any manner other than that specified in this manual.
The probe is tested for the zone in which there is a risk of explosion. Equipment group II,
category 2, only for use up to ATEX zones 1 and 21.
The probe (especially the type plate) must not be cleaned with or come into contact with acetone
or p-Xylene, or any liquids containing these solvents.
The free end of the feed hose must be connected either outside of the zone at risk of explosion or
within equipment approved for the equipment category in question.

General information
2.1.2 Warning labels
Read all labels and tags attached to the instrument. Failure to do so may result in personal
injury or damage to the instrument.
This symbol may have been attached to the device, and in such cases it references the instruction manual for
operating and/or safety information.
This symbol may have been attached to a housing or barrier in the product and warns that there is a risk of
electric shock and/or danger of death by electrocution.
Electrical equipment marked with this symbol may not be disposed of in European domestic or public disposal
systems after August 12, 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
manufacturer for disposal at no charge to the user.
Note: Instructions on the correct disposal of all (marked and unmarked) electrical products supplied or
manufactured by Hach-Lange may be obtained from your local Hach-Lange sales office.
2.2 Areas of application
Figure 2 Overview
1 Basin sensor 2 Installation sensor (TriClamp)
The TSS EX1 sc sensor is an extremely accurate turbidity and solid sensor made from
stainless steel for color-independent measurement of highly concentrated sludges.
This sensor was specially developed for use in ATEX zones up to 1 and 21 maximum
(equipment group II, category 2) and is available in a basin version or an installation
version (TriClamp).
2.3 Measuring principle
2.3.1 Turbidity according to DIN standards
Turbidity is measured in accordance with DIN standard EN 27027 (ISO 7027) and is
calibrated by the manufacturer. Measurement is exceptionally simple and accurate.
2.3.2 Measurement of solids according to plant-specific curves
Software-based optimization routines enable extremely precise simulation of
medium-specific calibration curves with few calibration points. Usually, a single calibration
point is sufficient.
8
Up to three calibration points can be defined for a strongly fluctuating medium. The
combined multiple-beam alternating light technique records solids in the medium with
even greater accuracy.
2.4 Handling
Switch off the sc controller before connection or disconnection of the probe and sc controller.
Protect the probe from impacts and never rest the probe on the measurement head.
Never operate the probe within powerful magnetic fields! (EN50021 6.4)

2.6 Function check
After unpacking and checking for any transport damage, perform a function check for all
components outside the ATEX zone.
1. Connect the sensor to the sc controller (refer to 3.3, page 12).
2. Switch on the power supply to the sc controller.
3. If no warning or error messages are displayed, the function check is complete.
The display is activated and the sensor enters measurement mode.
Note: The measurement value that is shown in air is not relevant.
