4.1 General

Easy calibration and maintenance free “fit and forget” performance mean that
you can install the i-Series Intelligent Sensor Level Monitoring S ystem rapidl y
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 re­ceived 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:

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 vo ltage cab les or electrical inverter wiring in close
proximity to the Sensor cabling.

Before feeding the rated voltage the sensor installation must be correctly com­pleted. The installation should be carried out by qualified personnel only. Further
statutory standards, regulations and technical rulings have to be taken into ac­count.
The sensor protection rating is IP68.
Please check if the power supply of the i-Series Intelligent Sensor must be inte­grated 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.

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.

6.3.4 Cable

The i-Series Intelligent Sensor comes with a fitted integral cable; if this cable is
extended then the total capacitance must not exceed the limits for the voltage
applied.

Important Information
In the case of the Ex mb version the cable is fitted with an over current protec-

6.3.5 Typical wiring for a Non-Hazardous location

tion device in the form of a fuse, please note that under no circumstances
should this fuse be removed. The fuse must be fitted in the non-hazardous
area.

The HART modem and PC or HART programmer are used to set up the opera­tion parameters for the i-Sensor. The output can either be as a 4-20 mA current
giving level or distance or as a digital signal via a HART master.
The i-Sensors cable is a twisted pair with overall cable screen. The twisted pair
are red and black, connect the red to +V and the black to -V. The screen should
go to signal ground.

Loop Resistance
For two wire operation the maximum cable resistance allowable can be calculat­ed from the graph below. For example if an i-Series Intelligent Sensor was sup­plied from 24 V, the maximum total cable resistance is 600 ohms, for a typical
77 ohm /km cable this would mean a maximum cable length of 600/77 = 7.8 km,
remember this total cable resistance, so this figure has to be divided by 2 to give

3.9 km max distance.

will appear, select the appropriate communications port and then close the win­dow.

7.5 Parameter Defaults

7.5.1 Factory Defaults

When first installing the i-Series Intelligent Sensor, or subsequently moving or
using the unit on a new application, before proceeding to program the unit for
its intended application it is recommended that you ensure that all parameters
are at their default values by completing a Factory Defaults P930, as de­scribed in Chapter 5 Parameter Guide

Once you are satisfied with the installation, and the i-Series Intelligent Sensor is
reading what you would expect in terms of distance from the face of the Sensor
to the material level, then you can proceed with any programming, required for
the intended application. It is sensible to program all of the required parameters
at the same time. The system will be then set-up.

8 Getting Results with Your i-Series Intelligent Sensor

This chapter explains how to undertake the various functions of your i-Series In­telligent Sensor. Where specific parameters are used, consult Parameter Guide
in Chapter 9.

8.1 Setting up Your Application

8.1.1 Empty Distance

Empty Distance (P105) is the distance from the face of the Sensor to the materi­al at the bottom of the vessel.

8.1.2 Span

Span (P106) is the distance from the empty level (0 % full) to span (100 % full).

8.1.3 Near and Far Blanking

Near blanking (P107) is the distance from the face of the Sensor that the i­Series Intelligent Sensor will not record a level nearer than. A typical reason to
increase this from the default value would be if you wish to ignore close in ob­structions.
Far blanking (P108) is the distance (as a percentage of empty level) beyond the
empty level that the i-Series Intelligent Sensor will read, the default is plus 20%
of empty level. If you wish to monitor further than the empty level, then increase
this figure, so that the empty level plus the far blanking figure (as % of empty
level) is greater than the surface being measured, within the capability of the
Sensor being used.

8.2 Using the 4-20 mA Output

The mA output can be used to monitor remotely what the i-Series Intelligent
Sensor is measuring, so it can be displayed remotely, integrate d into a PLC, or
used to generate a record using a chart recorder or similar.
By default, the i-Series Intelligent Sensor will provide a 4-20 mA output that is
proportional to level and can be overwritten as follows.

By default, the 4-20 mA will represent the operational span of the i-Series model
in use, with empty (0 % full) = 4 mA and full (100 % of the operational span) = 20
mA, but you may wish to only represent a section of the operational span. For
example, the application may have an operational span of 6 metres, but you
may only wish to represent empty level to 5 metres. If so, change P834 (Low
Value) to 0, and P835 (High Value) to 5.0.
If the device connected to the mA output is out of calibration, and cannot be cal­ibrated, then the low and high current levels can be trimmed by altering P838
(Low Trim) and P839 (High Trim). To do this, simply enter the value that ensures
that 4 mA or 20 mA respectively are shown on the remote device. You can use
the left/right menu keys to alter the value until the correct reading is shown on
the remote device, rather than typing in a value.

8.3 Setting Security Passcodes

A passcode is used to protect parameter entries and will be required when ac­cessing parameters with certain PC Software’s.
You can set a new passcode to prevent anyone changing any of your settings
within your i-Series Intelligent Sensor. The default passcode is 1997, but this
may be changed as follows.

Additional Information
The passcode is also used for remote access using certain PC Software’s, so

8.3.1 Changing the Passcode

if this is being used, be sure to ensure any additional equipment using this
feature is changed accordingly.

You can set the passcode to any number from 0000 to 9999. To do this, select
P922 which is the passcode parameter which can be changed as required.

8.4 Resetting Factory Defaults

If you need to restore parameters to their original factory settings, then access
parameter P930, which is the factory defaults parameter, change the value to 1
and ENTER, all parameters, with the exception of the mA trims, will be restored
to the factory settings (including the DATEM trace) and on completion.

8.5 Checking the Information Specific to your i-Series Intelligent Sensor

There are some parameters dedicated to each individual i-Series Intelligent
Sensor, such as the software revision and the unit’s s e r ial num ber .

8.5.1 Checking the Software Revision and Serial Number

If you need to identify the serial number of the unit or the current level of soft­ware in your i-Series Intelligent Sensor, the following parameters can be used.
Select parameter P926 to view the identity of the current software revision or
P928 for the serial number of the unit.

(P105) and 100% of span (P106).

These parameters are used to create a profile of the vessel when P600 = 11
(universal linear) or P600 = 12 (universal curved). You should enter breakpoints
in pairs, a reading for level and its corresponding volume. The more pairs you
enter, the more accurate the profile will be. In the case of universal linear, then
enter the level/volume at each of the points where the vessel changes shape. In
the case of the universal curved, enter values around each arc tangent, as well
as at the top and bottom.
You must enter at least two pairs, and you can enter up to 16 pairs.

Universal Linear (P600 = 11)

This volume calculation creates a linear approximation of the level/volume rela­tionship, and works best if the vessel has sharp angles between each section.

You should enter a level/volume breakpoint for each place where the vessel
changes direction, and numerous where the section is slightly curved (mostly
linear, but has got a small arc). You can enter any number of pairs between 2
and 16.

Universal Curved (P600 = 12)

This volume calculation creates a curved approximation of the level/volume rela­tionship, and works best if the vessel is non-linear, and there are no sharp an­gles.

You should enter 2 level/volume breakpoints at the minimum and maximum lev­els, and several for each place where the vessel has got an arc. You can enter
any number of pairs between 2 and 16.

P696 Reset Breakpoints

This parameter allows the resetting, to the default value, of all previously set
breakpoints (P610-673), without having to access them individually. When it is
necessary to reset or amend particular breakpoints this can be achieved by di­rectly accessing the desired parameter (P610-673) and changing as required.

P697 Number of Breakpoints Set

This parameter allows you to review the number of breakpoints that have been
set, without the need to access each individual one in turn, this is a “Read Only “
parameter and no values can be entered.

3 = Low

Will fail to the low value (empty)

9.4 mA Output

P834 mA Low Level

P835 mA High Level

P838 mA Low Trim

This parameter sets, in Measurement Units (P104), the value of ‘level’, ‘distance’
or ‘space’, depending on the selected Mode of Operation (P100), at which 4 mA
will occur.

This parameter sets, in Measurement Units (P104), the value of ‘level’, ‘distance’
or ‘space’, depending on the selected Mode of Operation (P100), at which 20
mA output will occur.

If the device you are connected to is not calibrated, and not showing the low val­ue, then you can trim it using this parameter. You can either type in the offset di­rectly, or use the arrow keys to move the output up and down until you get the
expected result on the device that is connected.

P839 mA High Trim

If the device you are connected to is not calibrated, and not showing the high
value, then you can trim it using this parameter. You can either type in the offset
directly, or use the arrow keys to move the output up and down until you get the
expected result on the device that is connected.

P808 Fail-safe Mode

By default, if a fail-safe condition occurs, then the display, relays and the mA
output are held at their last known values until a valid r ead ing is obtai ne d.
If required, then you can change this so that the unit goes to high (100% of
span), or low (empty) as follows:

P809 Fail-safe Time

In the event of a fail-safe condition occurring the fail safe timer determines the
time before fail-safe mode is activated. Default = 2.00 mins
If the timer activates, the unit goes into fail-safe, as determined by P808, (Dis­play and P840 (mA Output). When this happens, you will see the message
“LOE!” on the display.
When a valid measurement is obtained then the display, relays and mA output
will be restored and the timer is reset.

P851 Measurement Offset

The value of this parameter is added to the measured distance, in Measurement
Units (P104).
This Offset will be added to the level, as derived from the Sensor, and will affect
everything including the reading on the display, the relay setpoints and the mA
output.

P852 Temperature Source

Default = 1

This parameter determines the source of the temperature measurement. By de­fault it is set to internal Sensor (P852 = 1), which will automatically detect the
temperature from the Sensor. If for any reason, no temperature input is received,
then the Fixed Temp value is used, as set by P854.

The temperature source can be specifically set as follows:

i-Series Sensors

P854 Fixed Temperature

This parameter sets the temperature, in degrees centigrade to be used if

P852 Temperature Source = 3 (Default = 20 °C)

P860 Sound Velocity

This option allows for the velocity of sound to be changed accordin g to the
atmosphere the Sensor is operating in. By default the velocity is set for

342.72 m/sec which is the speed of sound travelling in air at a temperature of
20°C.
The table below gives details of the velocity of sound in various gaseous atmos­pheres In all cases the velocity indicated is that in a 100% gaseous atmosphere
at 0°C. In atmospheres less than 100 % it may be necessary to check the level
indicated at near empty and near full and compare with the actual level, several
times, then adjust the Sound Velocity accordingly to obtain an accurately dis­played reading.

9.6.1 Damping

P870 Fill Damping

The sound velocity in air increases or decreases at a uniform rate of
60 cm/sec. per °C, however in atmospheres other than air it will change at a dif­ferent rate.
This option allows the rate of change in cm/sec. per °C to be set according to the
atmosphere and temperature present. The level indicated, should be compared
with the actual level, several times, then Vapour Temperature Compensation ad­justed accordingly, to obtain an accurately displayed reading.
Default = 60 cm/sec. per °C

Damping is used to damp the display, to enable it to keep up with the process
but ignore minor surface fluctuations.

P871 Empty Damping

9.6.2 Filters

P881 Fixed Distance

P884 Peak Percentage

This parameter determines the maximum rate at which the unit will respond to
an increase in level. It should be set slightly higher than the maximum vessel fill
rate. Default = 10.000 metres/minute (32.81 feet/minute)

This parameter determines the maximum rate at which the unit will respond to a
decrease in level. It should be set slightly higher than the maximum vessel emp­ty rate. Default = 10.000 metres/minute (32.81 feet/minute)

This parameter determines the width of gate to be used in tracking an echo and
under normal circumstances will not require changing, but it can be increased in
the cases where the surface is moving extremely fast (in excess of 10 m/min) to
ensure smooth processing of the changing level.

When P102 = 2 (Solids), this parameter can be used to determine the point at
which the measurement is taken, within the established gate of the selected
echo, in order to compensate for any error that maybe caused by “angles of re­pose” presented by the way the material settles. Please consult NIVUS GmbH,
for further information and assistance on changing the value of this parameter.

12 Maintenance and Cleaning

During standard use the NivuMaster sensor does not get in contact with the
measurement medium and therefore is virtually maintenance-free. If the sensor
face however should get dirty due to medium contact (immersion) or ambient
conditions (dust) clean the sensor face carefully with a damp cloth.
Never use aggressive cleansing agents (such as thinner). For heavy pollution
NIVUS recommends the use of surface-active agents. The use of abrasive
cleansing agents is not allowed.

If you wish to clean or dismantle the sensor please disconnect the unit from
mains before.

No hard objects such as wire brushes, rods, scrapers or similar shall be used to
clean the sensor. Using a high pressure cleaner may lead to sensor damage
and measurement failures and thus is not allowe d.

In various countries it may be necessary to carry out regular maintenance with
comparative measurements in particular applications to comply with official regu­lations. If desired, NIVUS is going to carry out all required verifications, h ydrau lic
and technical assessment, calibration, troubleshooting and repairs if an accord­ing maintenance agreement has been contracted. These services will be carried
out according to DIN 19559 incl. the agreed proof of the remaining residual er­ror, as well as according to rules in the respective countries.

i-Series Sensors

13 Emergency

In case of emergency

- press the emergency-off button of the main system or

- set the slide switch on the unit to OFF.

14 Dismantling/Disposal

The device shall be disposed according to the local regulations for electronic
products.
