Thank you for choosing NIVELCO.

We are sure that you will be satisfied throughout its use!

1. INTRODUCTION

Application

NIVOTRACK M-30 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 most suitable applications are with
liquids free of solid particles and with low viscosity both in ordinary and
hazardous locations.

Its high precision renders NIVOTRACK suitable for custody transfer
measurement of valuable liquids such as fuels, solvents, alcohol distillates,
etc. Plastic version of the series substantially expands the field of
application by a wide range of aggressive materials.

Operating principle

The magnetostrictive transmitter is using the special feature of the
magnetostrictive wire spanned in the rigid or flexible probe. An electric
excitation signal given to the magnetostictive wire develops a twist in the wire
at the interference point with the magnetic disc placed in the float. The twist
travels back to the electronics in the form of an acoustic wave with defined
velocity. Measurement is based on measuring the flying time 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 and volume (tank content)
can be calculated.

3.4 MAINTENANCE AND REPAIR E

The unit does not require routine maintenance, however the probe may need occasional cleaning to remove surface deposits. Repairs will be performed at
Manufacturer’s premises. Units returned for repair should be cleaned or disinfected by the customer.

BKI 02 ATEX 278X ♦ mba3052a0600p_01 ♦ 13 / 40

4. INSTALLATION

4.1 MOUNTING

• The unit should be located in an area, which allows easy access for service, calibration and monitoring.

• Waving, turbulence and heavy vibration affects accuracy of the measurement. Thus the unit has to be installed far away from devices or places causing

such disturbance for instance from openings for filling or emptying. These affects can be attenuated in applications with rigid tube probes by the use of
stilling pipe along the whole probe. Kindly consult Nivelco distributor!

• To ensure consistent and durable operation the process fluid should be free of suspended solids or materials, which could stick between the float and the
guide tube.

• The unit should be protected against direct heat radiation.

• Design dimensions of the unit and the tank as well as calculations should be checked before mounting.

• Before installation a preliminary operational check is suggested.

• Should manufacturer setting be changed it is to perform as per chapter 5.

• The unit is offered with a wide variety of process connections according to the order codes Tank opening exceeding the float diameter is recommended for

insertion. Should this not be possible the float has to be removed from the (rigid or flexible) guide inserted through the opening and the float must be
reattached from inside of the vessel. The word “UP” etched on the float is to ensure mounting the float in correct position.

• Insertion position of the MEU and MGU types can be adjusted. Free length over the tank however must
not be longer than 200 mm.

• Units with flexible tube of type MK … MN are provided with weight for spanning of
the tube and keeping it in position. Weight and fastening nut are part of the unit.When
lowering down the flexible tube (with the weight at his end) to the bottom of the tank,
special care has to be taken to avoid interlocking or twisting and the coil diameter must
not be smaller than 60 cm. Dropping or twitching may damage the unit. Float or floats
should be placed next to the weight to avoid its hitting against the weight. Proper
spanning can be checked by the analogue signal or on the display. If the float is at the
lowest point I

out

< 4 mA or display should read < 0 mm

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.

4.2 WIRING

This transmitter is designed to operate on 12 … 36 V DC power only.
The maximum loop resistance (including barrier resistance) is depending on the voltage
of the power supply and can be between 0 and 1200 Ohm. Calculation formula can be
seen in the Technical Table under Output Load. Using transmitter with HART a terminal
resistance with a minimum value of 250 Ohm should be applied.
The power supply should be interconnected with the unit with twisted, shielded cable that
can be pulled through the cable conduit. The cable can be connected to the terminal strip
after removing the cover and the display unit.
CAUTION: the enclosure of the transmitter should be grounded.Grounding resistance
should be < 1 Ohm. Shielding of the interconnecting cable should be grounded at the
end of the control room. To avoid disturbing noises the interconnecting cable must not be
led near to high voltage cables. Especially critial are inductive couplings of AC harmonics
against which the protection of shielding is not effective.

4.3 LOOP CURRENT C HECKING

After removing the cover and the display module the actual loop current can be measured with an accuracy of 0,5 % by connecting a voltmeter (in the range of
200 mV) to the points indicated on the drawing above

5. PROGRAMMING

The NIVOTRACK can be programmed by the following two ways:

• Programming without Display Module see 5.1.
Assignment of the levels to the 4 and 20 mA current output, error indication by the analogue signal and damping can be set.

• With the SAP-201 Display Module, see 5.2.
All features of the unit can be set, such as measurement configuration, zero offset, , output assignments, measurement optimisation 32-point linearisation,
dimensions
for 11 tanks with different shape.

Devices with the type number NIVOTRACK MB-3 and MG-3 are already equipped with the SAP-201.

The NIVOTRACK is fully operational without the SAP-201. The SAP-201 is only needed for programming and/or displaying measurement values.

BKI 02 ATEX 278X ♦ mba3052a0600p_01 ♦ 16 / 40

The unit will measure during programming in accordance with the previous parameters. The new, modified parameters will only be effective after
returning to the Measurement Mode

If the transmitter is left in Programming Mode by mistake, it will automatically return to Measurement Mode after 30 minutes and will operate with the parameters
entered during the last completed programming.

FACTORY SETTING (Default)

The

NIVOTRACK will be delivered with the following Factory Default:

⇒ Current output, display and bargraph: LEVEL

⇒ Current output and bargraph proportional to the level

⇒ 4 mA: assigned to the minimum level 0%

⇒ 20 mA: assigned to the maximum level 100%

⇒ Error indication by the current output: hold last value

A couple of millimetres of fluctuation of the basic DIST value (e.g. due to

BKI 02 ATEX 278X ♦ mba3052a0600p_01 ♦ 29 / 40

P04 Zero point distance from the tank bottom (H) (Zero offset of the unit)

This parameter is for arranging zero offset which represents virtual expansion of the measurement range. Obviously measurement will only
be performed in the range, therefore in case of zero offset, displayed value will always be over zero and analogue output over 4 mA.
Should zero offset not be required this parameter will be unchanged. Zero offset will be performed by setting in this parameter the value of
distance between the tank bottom and the low-end position of the float. (See BASIC CONCEPT OF MEASUREMENT WITH NIVOTRACK on
page 3)
Programming of the analogue output in P10 will not be influenced by the zero offset.

FACTORY DEFAULT: 0

P05: Zero point distance from the high-end position of the float (Zero offset within the range)

This parameter is for arranging zero offset within the measurement range. Obviously this represents the reduction of the measurement range.
The value of this parameter will be the distance between the required low (zero point) position and the high-end position of the float.
Analogue output in P10 should be programmed accordingly i.e. if P05≠0 then P05 = P10.

FACTORY DEFAULT: maximum measurement range i.e. distance between the low- and high-end position of the float

P08: Fixed value of the analogue output

This parameter is for setting analogue output for fixed value.
Setting value between 3.8 and 20.5 mA in this parameter this fixed value will appear on the analogue output. This also will overwrite all error
indications and in case of P19 ≠ 0 the value of the output current will be (instead of 4 mA) the value set here.
If the parameter is 0, the current output will be according to the settings in the other parameters.

FACTORY DEFAULT: 0

BKI 02 ATEX 278X ♦ mba3052a0600p_01 ♦ 30 / 40

6.2 CURRENT OUTPUT

P10: Value (of distance, level, volume or flow) assigned to 4 mA current output

P11: Value (of distance, level, volume or flow) assigned to 20 mA current output

Values are interpreted according to P01(a). Please note that in case of programming for (LEV or VOL) % measurement the min and max value
has to be entered in the relevant engineering units of LEV (m, ft) or VOL (m3, ft3).
Assignment can be made so that the proportion between the change of the (measured or calculated) process value and the change of the current
output be either direct or inverse. E.g. level 1 m assigned to 4mA and level 10 m assigned to 20 mA represents direct proportion and level 1 m
assigned to 20 mA and level 10 m assigned to 4 mA represents the inverse proportion.
Remember. if P05≠0 then P05 = P10!

FACTORY DEFAULT: P10 = 0 and P11 = measurement range (m)

P12: - - - a Error indication by the current output

In case of error the NIVOTRACK will provide one of the current outputs below. (For errors and their interpretation see Chapter 7).

a ERROR INDICATION (ACCORDING TO NAMUR)

2 22 mA

FACTORY DEFAULT: 0

P19: HART address (applies for models with HART)

The short address of the unit can be selected for 0 to 15. If one unit is involved the address should be 0 (thus P19=0) and the 4-20mA is
operational. In Multidrop applications (with more than one unit) the address should be other than 0-tól P19≠0, and the output will be fixed to 4mA
provided P08=0.

If the Secret Code is activated, the parameters can only be viewed, this is indicated by the a flashing colon “:” between the parameter address
and the parameter value. In order to program the device locked by a secret code, first enter the Secret Code in P99. The Secret Code is re­activated each time the EchoTREK is returned to Measurement Mode.
To delete the Secret Code, enter the Secret Code in P99. After confirming it with [E] re-enter the parameter P99 and enter 0000.
[dcba (Secret Code) ] → [E] → [E] → [0000] → [E] ⇒ Secret Code deleted
