Thank you for choosing a NIVELCO instrument.
We are sure that you will be satisfied throughout its use!
1. INTRODUCTION
Application
NIVOTRACK MI−, MX−, MY−5 series working on the
magnetostrictive principle are suitable for high accuracy level measurement
of storage tanks. Due to their high temperature and pressure rating these
units can also be used for level gauging of technological tanks. The 2-wire
magnetostrictive level transmitters are an ideal solution for high accuracy
measurement of clean fluids.
Operating principle
The magnetostrictive transmitter is using the special feature of the
magnetostrictive wire spanned in the rigid probe. A magnetic field excited in the
magnetostrictive wire develops an acoustic wave in the wire. From the
interference point with the magnetic disc placed in the float the wave travels
back to the electronics with defined velocity. Measurement is based on the time
of flight of the acoustic wave since it is proportional with the distance of the float
from the electronics.
The above distance constitutes the basis for all output signals of the
NIVOTRACK! With the help of further mechanical data level can be calculated.

If the float removed, when reinstalling it, make sure that the "UP" marking is on the top of the float. Ensures that the float is mounted back in the correct position and that the
fastening nut is securely fixed in the position before dismantling. If a float larger than 2" is used, it is recommended to order a pre-mounted flange.
ATTENTION! If the fastening nut is not secured properly, the float may slide off the measuring tube when the tank is empty, causing the instrument to be unable to
measure!

4. INTEGRATION INTO THE TECHNOLOGICAL PROCESS (INSTALLATION, WIRING)
When choosing the installation place please ensure proper space for later calibrations, verification or maintenance service.
Waving, vortex or vibration effects have negative influence on the measurement accuracy. To avoid these effects, the mounting placement should be
as far as possible from the sources of these disturbing effects for instance from openings of filling or emptying. These effects can be attenuated in
applications with rigid tube probes by the use of stilling pipe along the whole probe. Please consult with a NIVELCO distributor!
To ensure consistent and durable operation the measurement medium should be free of suspended solid materials, which could stick between the
float and the probe.
The unit should be protected against direct heat radiation.
Prior to the installation the mounting dimensions of the unit and the tank as well as the calculations should be checked carefully.
Prior to the installation a preliminary operation check is suggested.
If necessary to change the default factory settings the programming should be performed in accordance to the description in the 5th chapter.
The units are offering a wide variety of process connections according to the available order codes. The tank opening should be fit for the selected
level transmitter by means of the insertion hole is bigger than the float diameter. If this is not possible the float has to be removed from the probe and
when the unit is mounted into the tank the float can be mounted from inside of the vessel. The “UP” marking on the float ensures that the float is
mounted back in the correct position. See the drawing! Prior to finishing the mounting the spacer needed to assemble back between the float and the
counterweight.
ATTENTION!
In order to avoid damaging the probe, do not put it to torsion when installing or removing the unit. Therefore, special care has to be
taken when the process connection is being screwed into or out of the flange. The best is to hold the rigid part of the probe with a
suitable tool as long as the process connection is tightened to its place. Sliding sleeve must not be loosened during operation.

mia505en2102p  13 / 16
4.1. WIRING
This transmitter is designed to operate on 12.5…36 V DC power only.
The measured voltage on the terminals of the unit should be at least 12.5 V. Using transmitter with HART®a terminal resistance
with a minimum value of 250 Ωshould be applied.
CAUTION! the enclosure of the transmitter should be grounded. Grounding resistance should be R 1 Ω. Shielding of the
interconnecting cable should be grounded at the control room side. To avoid disturbing noises the interconnecting cable must not
be led near to high voltage cables. Especially critical are inductive couplings of AC harmonics against which the protection of
shielding is not effective.
5. PROGRAMMING
LED display:
continuously lit: normal operation
off, 1 brief flash: no echo
off, 2 short flashes: excitation signal generation error
off, 3 short flashes: current generator fault, current output does not match device set program
lit, 1 short-term non-lighting: saturation
Parameters can set using a HART®modem, EView2, or PACTware™ program or MultiCONT process controller.
Parameters are entered as 4 place value decimal numbers for the parameters where it's indicated. Indication of each place value ’ d c b a ’, unused place
values in the description: (-). The instrument ignores unused place values.
P0: - c b -: Measuring unit, Dimension of the measuring unit
Parameter: P0:c, Measuring unit
Description: This should be configured as the first step of the programming. Here you can choose the default unit system:
•c = 0: EU – European unit system
•c = 1: US – Anglo-Saxon unit system
Default measuring unit system: c = 0: EU
Parameter: P0: b, Dimension of the measuring unit
Description: The dimension of the unit can be specified in this menu:
•EU European unit system: b = 0: m; b = 1: cm; b = 2: mm
•US Anglo-Saxon unit system: b = 0: ft; b = 1: inch
Default measuring unit: b = 2: mm
ATTENTION! If the unit system or measuring unit is changed, after a warning message the device resets all the parameters.

mia505en2102p  14 / 16
P1: - - - a: Primary value (PV) source
Parameter: P1: a
This mode determines the primary value and the displayed value. It also determines the value which will be proportional to the output current.
•• a=0: DISTANCE
•• a=1: LEVEL
Default value: a=0 (DISTANCE)
P4: Zero-point offset
Description: This Parameter is used for zero-point offset. In level measurement mode the zero level is meant at the lowest position of the float. Due to the
construction of the device, it cannot able to measure the level through the whole height of the tank, because it may not reach the bottom of the tank. In
this Parameter the distance between the lowest position of the float and the bottom of the tank can be entered.
The offset value will be a negative value (the value of the Parameter is always the distance between the lowest position of the float and the zero-point
offset of the measurement) this negative number should be entered into the Parameter if the measurement range needs to be decreased virtually. The
absolute value of this number shall be less than the active measurement range. Wrong configuration of the zero-point offset can result negative level
display. The current output can go below 4 mA, but saturates at 3.9 mA.
If there is no need to use Zero-point offset, enter zero in the parameter.
Default value: 0.
P8: Fixed output current
Description: Parameter for setting the fixed output current, but this only appears on the output when parameter P12: b is set to MANUAL.
Values between 3.8 and 20.5 can be entered. The output current will be set to the entered value and analogue transmission will be suspended. This error
indication overrides all other error indication.
Default value: 4 mA
P10: Output current value 4 mA
Description: Measured value assigned to 4 mA. The transmitted value is in accordance to the primary value (PV) (P01:a).
Assignment can be done that the change in measured value and the change in the output value are the same (normal), or opposite directional (inverse
operation). For example: 1 m level is 4 mA, 10 m level is 20 mA, or 1 m level is 20 mA and 10 m level is 4 mA.
Default value: 0 mm

mia505en2102p  15 / 16
P11: Output current value 20 mA
Description: Measured value assigned to 20 mA. The transmitted value is in accordance to the primary value (PV) (P01:a).
Assignment can be done that the change in measured value and the change in the output value are the same (normal), or opposite directional (inverse
operation). For example: 1 m level is 4 mA, 10 m level is 20 mA, or 1 m level is 20 mA and 10 m level is 4 mA.
Default value: Maximum measurement range accordance to the nominal length of the device (mm).
P12: - - b a: Output current mode, Error mode
Parameter: P12: b, Output current mode
Description: Current transmitter mode [AUTO, MANUAL]
•b = 0: AUTO, output current value is calculated from the measured value.
•b = 1: MANUAL, The Output current is the fixed current set-in parameter P8. In this case, the output current error setting is not valid either!
Default value: AUTO
Parameter: P12: a, Error mode
Description: “Error indication” by the current output
•a = 0: HOLD, Error indication has no effect on the output current. In this case, it holds the last valid measurement result at the output.
•a = 1: 3.8 mA, Error indication: the output current gets 3.8 mA.
•a = 2: 22 mA, Error indication: the output current gets 22 mA.
Attention! This error indication is active unless the failure is fixed, or until the failure terminates.
Default value: HOLD
P19: HART polling address
Description: HART polling address of the device (0…15).
The polling address can be set between 0 and 15. For a single instrument the polling address is 0 and the output is 4…20 mA (analogue output).
If multiple units are used in HART Multidrop mode (max. 15 pcs.) the polling addresses should differ from 0 (1…15), in this case the output current will be
fixed at 4 mA.
Default value: 0
P20: Damping time
Description: Damping time is used to damp the unwanted fluctuations of the output and display. If the measured value changes rapidly the new value will
settle with 1% accuracy after this set time. (damping according to an exponential function).
Adjustable values: 0…99 sec.
Default value: 0 sec
