SAFETY
Please read this manual carefully before un- packing, installing or operating the device.
Although the operation of the SulfiLogger
™
sensor is straightforward, it is mandatory to be familiar with the content of this manual. Failure to do so may result in serious injury to operators or other persons, or damage to equipment. Do not use or install the Sul- fiLogger
™
sensor and auxiliary equipment
in any other way than specified in this man- ual. Special attention must be paid to all danger and caution statements. Do not use the SulfiLogger
™
sensor outside the speci-
fied electrical, mechanical and thermal pa-
rameters as specified in the data sheet. Dur- ing the installation, please wear personal protective equipment (PPE) according to the safety regulation of the installation site. Hazard statement nomenclature

DANGER Indicates a potentially or imminently hazardous situation which, if not avoided, could result in death or seri- ous injury.
!
CAUTION Indicates a potentially hazardous situ- ation that may result in minor or mod- erate injury.

IMPORTANT NOTE Information that requires special em- phasis.
Hazardous areas - SulfiLogger™ sensor EX version •
Pay close attention to other EX equip- ment used in conjunction with the Sul- fiLogger™ sensor.
•
Observe the specifications in the certifi- cate as well as national and local regula- tions.
•
Ensure that all personnel are suitably qualified.
•
Always use approved EX barriers for in- stallation.
Chemical and gas handling safety

DANGER Handling hazardous gases such as hy- drogen sulfide or chemical samples containing dissolved sulfides can be dangerous. Users of this product are advised to familiarize themselves with safety procedures, use of personal pro- tective equipment (PPE) and the cor- rect use of gases and/or chemicals, and to carefully read all relevant Safety Data Sheets.
Installation and calibration of the SulfiLog- ger
™
sensor may include the risk of con-
tact with hazardous gases or liquids. Hydro- gen sulfide is a highly toxic gas and special precautions are needed to avoid the risk of injury or death. Furthermore, the installa- tion of the SulfiLogger
™
sensor in applica-
tions such as sewer networks or other facil- ities containing raw wastewater includes a risk of contact with a range of other chem- ical and biological threats, and any opera- tor performing installation or service on the SulfiLogger
™
sensor in such environments
should therefore be trained in the environ- mental safety and need of PPE for the given application. This manual does not cover any such training. The use of the SulfiLogger
™
sensor for specific applications may involve risks that are not mentioned here.
OVERVIEW
The SulfiLogger
™
sensor is available in dif-
ferent configurations in an ATEX certified
version (X1 sensors) and a non-ATEX certi-
fied version (S1 sensors). If your product is an ATEX certified product, it is crucial that you carefully follow the instructions re- lating to ATEX specific installation require- ments. EU - ATEX certification
The SulfiLogger™ X1 sensor has the follow-
ing marking:

Connection
The SulfiLogger
™
sensor has two connec-
tors: A 4-20 mA power connector (5-pin
M12 male) and an RS-232 connector (5-pin M12 female). We recommend using M12 plugs in stainless steel (EN 1.4404 / 316L).
These cables can be provided by Unisense.
Please note that products powered by a battery box may require special attention. Please refer to the latest User Manual. Port parameters Please note that the colors listed here only apply for cables supplied by Unisense. The SulfiLogger
™
is designed for 4-20 mA loop-
power. However, this connector can also be used only for DC supply. Power / 4-20 mA

Grounding
The SulfiLogger
™
sensor should always be
grounded. However, national, regional or local regulation may apply. For use in
ATEX-regulated areas, see EN/IEC 60079-
14. Unisense recommends that the SulfiLog-
ger
™
sensor is always grounded using the
M6 thread at the back of the device for a secure grounding connection.

DANGER Using a SulfiLogger
™
sensor from the
X1-series without grounding will void
the ATEX certificate.
