2.2 Use in accordance with the requirements
The i-Series Intelligent Sensor is a highly developed ultrasonic level measure-
ment system which provides non-contacting level measurement for a wide varie-
ty of applications in both liquids and solids. Its unique design gives unrivalled
performance in echo discrimination and accuracy in a loop powered device.
The device is exclusively intended to be used for purposes as described above.
Modifying or using the devices for other purposes without the written consent of
the manufacturer will not be considered as use in accordance with the require-
ments.
Damages resulting from this are left at user’s risk.
The device is designed for a lifetime of approx. 10 years. After that period an
inspection in addition with a general overhaul shall be made.
Ex-Protection
The Ex-version of the sensor is designed to be used in areas with explosive at-
mospheres (zone 1 or zone 0).
The transmitter always has to be installed outside of Ex-zones!
Approval (option)
Sensor: II 2 G Ex mb IIC T4 GB
II 2 D Ex mb IIIC T130°C Db
II 1 G Ex ia IIC T4 Ga
II 1 D Ex ia IIIC T103°C Da
The approval is only valid in connection with the respective indication on the
transmitter or the sensor nameplate.
For installation and initial start-up the conformity certificates and test certifi-
cates of the respective authorities must be followed.

3 General Notes on Safety and Danger
3.1 Danger Notes
3.1.1 General Danger Signs
Cautions
are framed and labelled with a warning triangle.
Notes
are framed and labelled with a “hand“.
Danger by electric voltage
is framed and labelled with the Symbol on the left.
Warnings
are framed and labelled with a “STOP“-sign.
For connection, initial start-up and operation of the NivuMaster Ultrasonic-
Sensors the following information and higher legal regulations (e.g. in Germany
VDE), such as Ex-regulations as well as safety requirements and regulations in
order to avoid accidents, must be observed.
All operations, which go beyond steps to install, to connect or to program the
device, must be carried out by NIVUS staff only due to reasons of safety and
guarantee.
3.1.2 Special Danger Notes
Please note that due to the operation in the waste water field, transmitter, sen-
sors and cables may be loaded with dangerous disease germs. Respective
precautionary measures must be taken to avoid damage to one’s health.

3.2 Device Identification
The instructions in this manual are valid only for the type of device indicated on
the title page.
The type ID label is wrapped around the sensor and contains the following
specifications:
- Name and phone number of manufacturer
- CE label
- Type and serial number
- Year of manufacture
- Ex-label (on Ex-version devices only) as mentioned in chapter 2.2.
It is important for enquiries and replacement part orders to specify article num-
ber as well as serial number of the respective transmitter or sensor. This en-
sures correct and quick processing.

3.3 Installation of Spare Parts and Parts subject to wear and tear
We herewith particularly emphasize that replacement parts or accessories,
which are not supplied by us, are not certified by us, too. Hence, the installation
and/or the use of such products may possibly be detrimental to the device’s abil-
ity to work.
Damages caused by using non-original parts and non-original accessories are
left at user’s risk.
3.3.1 List of Spare Parts
1. sensor complete
2. counter nut
3. holder bracket
3.4 Turn-off procedure
For maintenance, cleaning and repairs (authorised staff personnel only) the
device shall be disconnected from mains and shall be prevented from being
turned on again unintentionally.
3.5 User’s Responsibilities
In the EEA (European Economic Area) national implementation of the frame-
work directive 89/391/EEC and corresponding individual directives, in particular
the directive 89/655/EEC concerning the minimum safety and health require-
ments for the use of work equipment by workers at work, as amended, are to be
observed and adhered to.
In Germany the Industrial Safety Ordinance must be observed.
The customer must (where necessary) obtain any local operating permits re-
quired and observe the provisions contained therein.
In addition to this, he must observe local laws and regulations on
- personnel safety (regulations on safety at work)
- safety of work materials and tools (safety equipment and maintenance)
- disposal of products (laws on wastes)
- disposal of materials (laws on wastes)
- cleaning (cleansing agents and disposal)
- environmental protection
Connections:
Before operating the device the user has to ensure, that the local regulations
(e.g. for operation in channels) on installation and initial start-up are taken into
account, if this is both carried out by the user.

4 Functional Principle
4.1 General
Easy calibration and maintenance free “fit and forget” performance mean that
you can install the i-Series Intelligent Sensor Level Monitoring System rapidly
and with confidence, with calibration being achieved either by the use of a HART
programmer/calibrator or via a PC utilising the NIVUS interface and software.
The i-Series Intelligent Sensor operates on the principle of timing the echo re-
ceived from a measured pulse of sound transmitted in air and utilises “state of
the art” echo extraction technology.
4.2 Sensor Versions
i-Series Intelligent Sensor comes in four models:

All model types are available for use in hazardous area installations with either
Ex mb (zone 1) or Ex ia (zone 0) ATEX certification.
The i-Series Intelligent Sensor has a 4 to 20 mA output which can be pro-
grammed to give an output proportional to level, space, distance or volume, de-
pendant on the measurement mode selected and provides a ‘fault condition’
alarm of either 3.8 mA or 22 mA.

6 Installation
6.1 Power Supply Requirements
For electric installation the local regulations in the respective countries
(e.g. VDE 0100 in Germany) must be referred to.
The i-Series Intelligent Sensor operates from a DC supply of 10 to 28V and will
typically draw less than 22mA.
All electronic products are susceptible to electrostatic shock, so follow proper
grounding procedures during installation.
The compact one-piece construction of the i-Series Intelligent Sensor can be
mounted easily using either the 1″BSP/NPT rear mounting thread or the integral
1.5" or 2" BSP/ NPT, front thread, dependent on model.
When choosing a location to mount the i-Series Intelligent Sensor, bear in mind
the following:
- The ultrasonic signal path should be free of falling material and obstructions
such as pipes, beams etc.
- The i-3 should be mounted at least 12.5 cm (0.41 feet) above the maximum
level of the material and be perpendicular to the surface. While the i-6 and
10 should be mounted at least 30cm (0.98 feet) above the maximum level of
the material and be perpendicular to the surface. And the i-15 should be
mounted at least 50cm (1.64 feet) above the maximum level of the material
and again should be perpendicular to the surface
- The ambient temperature is between -40 ºC and 80 ºC.
- There should be no high voltage cables or electrical inverter wiring in close
proximity to the Sensor cabling.
Before feeding the rated voltage the sensor installation must be correctly com-
pleted. The installation should be carried out by qualified personnel only. Further
statutory standards, regulations and technical rulings have to be taken into ac-
count.
The sensor protection rating is IP68.
Please check if the power supply of the i-Series Intelligent Sensor must be inte-
grated into the facility’s emergency shutdown conception.

6.3 Installation and Connection of i-Series Sensors
6.3.1 General
The sensors mounting place has to be selected according to certain criteria.
Please strictly avoid:
- heat emitting objects (max. ambient temperature: +80 °C (176 °F))
- objects with strong electromagnetic fields (e.g. frequency converters, electric
motors with high power consumption or similar)
- corrosive chemicals or gas
- mechanical shocks
- vibrations
- radioactive radiation
- installation close to footpaths or travel ways
Removing or loosening cable glands results in leakage and causes a failure in
the measurement / the sensor.
No
sensor parts are allowed to be removed on principle!
To avoid disturbances from electrical interferences, the sensor cable must not
be laid close to (or parallel to) engine (motor) lines or main power lines.
