Thank you for choosing a NIVELCO instrument.
We are sure that you will be satisfied throughout its use.
1. INTRODUCTION
The EchoTREK SBD/STD-300 series compact ultrasonic transmitters from NIVELCO are designed to measure the level of most free flowing solids (powders
and granules). Level measurement technology based on the non-contacting ultrasonic principle is especially suited for applications where, for any reason,
no physical contact can be established to the surface of the material to be measured and/or moving parts are to be avoided to eliminate mechanical wear-
out.
A total beam angle of 5° at –3 dB is a feature of all NIVELCO’s ultrasonic sensors designed for the level measurement of free flowing solids. This uniquely
narrow beam angle ensures reliable measurement in narrow silos with uneven side walls or sometimes even in the presence of dusting. Furthermore, as a
result of the narrow beam angle – the emitted ultrasonic signals have an outstanding focusing – a sufficient signal penetration through dust is ensured.
PRINCIPLE OF OPERATION
The ultrasonic level metering technology is based on the principle of
measuring the time required for the ultrasound pulses to make a round trip
from the sensor to the level to be measured and back. The sensor emits an
ultrasonic pulse train and receives the echoes reflected. The intelligent
electronic device processes the received signal by selecting the echo
reflected by the surface and calculates from the time of flight the distance
between the sensor and the surface which constitutes the basis of all output
signals of the EchoTREK.

Minimum measuring distance (Xm): (also known as the “Dead Band”) is a feature common to all ultrasonic level meters. This is a short range in front of the
sensor within which the ultrasonic device can not measure. The immeasurable range (close-end blocking) should be increased by programming in order to
avoid any measurement error caused by improper mounting or placement of the level transmitter.
Maximum measuring distance (XM): The longest range under ideal condition within which the device can measure. No measurement is possible beyond this
distance.

3. INSTALLATION
PLACEMENT
To find the ideal position for the location of the EchoTREK level transmitter various
considerations should be made.
The transmitter should not be installed in the centre of the tank/silo when the tank roof is dome
shaped or conical. The ideal position for the EchoTREK is on the r = (0.3 … 0.5) R (in case of
cylindrical tank). Avoid that the 5° conical beam angle of the transmitter contact the tank/silo
wall. This case the transmitter is mounted too close to the wall, therefore it should be tilted (See
section “Aiming”).
To avoid overheating the instrument should be protected against direct sunshine.

GRAVITY FILLING
The device should be
mounted as far as possible
from the filling stream.
PNEUMATIC FILLING
Select a location where the speed of the
in-flowing material is the smallest.
Ex type units are not allowed to be
installed in the dust path of the
pneumatic filling!
Suggested location (view from above)
40 m 3,8 m
50 m 4,7 m
MOUNTING (see illustration of mounting options on the next page)
The EchoTREK consists of a sensor that is attached to the aiming arm (a pipe with a ball-joint housing incorporating a ball joint) that is attached to the housing
of the electronics. It is recommended to mount the transmitter on the roof of the tank/silo using a flange (See drawing). The Ball-joint housing has a screw-hole
diameter of 125 mm for fixing it. For easy installation we recommend to use our special flange with a split insertion, available with four sizes of
DN125/150/200/300 (to be ordered separately). Removing the split insertion, the flange is to be put around the aiming arm and the ball-joint housing is to be
fixed to the split flange. It is essential to use the washers and the bolts (4 pcs each) delivered with the split flange. The ball-joint will be pressed to the housing
by a spring allowing adjustment/aiming. The 4 pcs of M12 bolts have to only be tightened after completing the adjustment/aiming. The maximum torque for
tightening the bolts is 3.5 Nm.

10 / 48 ♦BKI16ATEX0020X ♦sbd31j0a0600p_03
Mounting EchoTREK versions S-33J-and S-34J-
1. Check the split flange for matching the bore-holes with that of the counter-flange on the silo
2. Remove the split insertion from the flange and put the flange around the aiming arm between the sensor and the Alu-base.
Slide the split insertion back to its place and screw the ball-joint housing to the flange with the 4 pcs M 12 bolts to such an extent that will allow free
movement of the aiming arm through and tilting by the ball joint for the aiming process.
3. Place the sealing below the flange (if necessary)
4. Pass the sensor through the opening cut on the roof and fasten the flange to its place.
5. Fasten the EchoTREK (with the split flange) to the counter-flange or to the roof of the silo/tank. Perform the aiming (See section “Aiming” below).
6. For fixing the position of the aiming arm tighten the 4 pcs M 12 bolts of the ball-joint housing (max. 3.5 Nm).
Mounting EchoTREK SD-31-versions, with silo/tank roof opening of ∅300 mm – 340 mm.
The procedure is the same as above but the required flange diameter is DN300.
Mounting EchoTREK SD-31-version with silo/tank roof opening less than ∅300 mm and the silo space is accessible from inside:
1. Check the split flange for matching the bore-holes with that of the bolt places or counter-flange on the silo
2. Place the sealing below the flange (if necessary)
3. Push the unit out of the silo (upwards) (See on the next page)
4. When the Alu-base with the ball-joint is above the counter-flange the special flange has to be placed around the aiming arm (See on the next page)
5. Put the split flange on the counter-flange and lower the ball-joint housing on it
6. Slide the insertion to its place (Seeon the next page)
7. Screw in the 4 pcs of M12 bolts (See on the next page) to such an extent that will allow free aiming
8. Fasten the EchoTREK (with the split flange) to the counter-flange or to the roof of the silo/tank.
9. After completing aiming, tighten the 4 pcs 12M bolts (max. 3.5 Nm).
If the entire tilting range of the aiming arm is required, the thickness of the roof can not exceed as specified on the drawing next page. The EchoTREK can also
be mounted on existing (manhole) covers, access lids or for instance on a steel structure lowered into a larger (for example: 0.5 x 0.5 m) opening on the roof.
This solution is to be used when the roof thickness is greater than 350 … 380 mm.
The apparatus nor any part of it is not suitable as a fire resistant barrier for the Zone 20 area.
The housing cover of the Ex type units can be only removed after screw in the hex socket set screw providing protection against unauthorized
(tool-free) opening of the cover. The instrument is allowed to be operated in hazardous environment only in case the cover is locked properly by the
described protective screw.

5. PUTTING INTO OPERATION, ADJUSTING, PROGRAMMING
5.1. PUTTING INTO OPERATION,USAGE
After switching on the correctly wired unit the transducer begins to click audibly. In about 20 … 50 s the ECHO LED goes on and a signal between 4 – 20 mA
appears on the current output. The factory default settings are suitable for checking the operation of the unit or solving most simple level metering tasks. For
using the advanced features of the EchoTREK it is required to modify the programming to customize it for the required measurement task. To get familiar with
the programmable features of the level transmitter and be able to solve challenging level measurement tasks it is strongly recommended reading carefully the
following chapters of this user's and programming manual.
FACTORY DEFAULT PARAMETERS
All the transducers get the same factory default parameters that can also be reset later if needed. Some of the most important parameters default values of the
EchoTREK SD-3 series can be found below:
⇒ Measurement mode: level measurement (LEV). The plug-in SAP-100 display shows level value.
⇒ Zero level is assigned to the maximum measuring distance (XM).
⇒ The output current and the bargraph of the SAP-100 module is assigned to the measured level value.
⇒ 4 mA and 0% is assigned to zero level (maximum measuring distance).
⇒ 20 mA and 100% is assigned to maximum level (minimum measuring distance).
⇒ Current output in case of error: holding the last measurement value.
⇒ Damping time: 300 s.
⇒ Relay is de-energized in case of „NO Echo”.
All the other measurement values are set to fit the values suitable for standard tasks. The functions used in special cases are switched off by default.
AIMING OF THE ECHOTREK FOR SOLIDS
To reduce week signal reflection from the material surface caused by an angle of repose building due to the filling and/or emptying process, it is recommended
to tilt the sensor by the aiming arm of the transmitter. The optimal tilting position can be adjusted during operation and recommended to be checked at multiple
levels during the filling / emptying process. In most cases, the sensor should be aimed towards the middle of the tank/silo bottom by aiming at the silo outlet.
In applications where repose is not present or with tall and narrow silos (diameter/height ≥ 5) aiming is not
critical: the sensor should face straight downwards. Aiming should also be tested also with full silo, since
due to the great angle of repose the echo might be weak despite of the fact that level is near to the sensor.
In such cases a reasonable compromise of aiming should be achieved that provide acceptable echo in
every state of the filling. Aiming is also aided by the informational parameters P70 – P75. Aiming procedure
is recommended to perform together with the full parameter access programming.

5.2. SPECIAL CONDITIONS FOR SAFE USE
 The equipment is not allowed to be installed in the dust path of the pneumatic filling!
 The apparatus nor any part of it is not suitable as a fire resistant barrier for the Zone 20 area.
 The instrument should be grounded by all its grounding screws to the EP system in order to avoid
electrostatic charges and due to the Class I. electronic protection classification.
 The diameter of the used cable should meet the specified dimensions of the cable gland.
 The device must be operated only with using properly sealed Ex ta certified protective cable glands.
 The current output should be connected to a galvanic isolator.
 The windows of the EchoTREK SBD-3-Ex devices are susceptible to electrostatic charges,
therefore cleaning is allowed only with a wet rag.
5.3. PROGRAMMING
The factory default settings can be changed by the user. The programming can be performed with using SAP-100 type plug-in programming module which is also a
field display. The EchoTREK SB-3 types include the SAP-100 programming module. After removing the windowed housing cover the programming buttons
can be accessed. The SAP-100 module is able to program any EchoTREK level transmitters for solids. The EchoTREK is able to operate without the SAP-100
module and it can be removed during operation. Remote programming via HART communication protocol or RS485 interface is the same as described except the
measurement simulation.
!
The instrument may be damaged by
electrostatic discharge (ESD) via its terminal
(SAP-100 and TEST), thus apply the
precautions commonly used to avoid
electrostatic discharge e.g. by touching a
properly grounded point before removing the
cover of the enclosure. A possible
electrostatic discharge can cause damage for
the instrument.

• the modified value is either out of the range, or
• the entered code is not valid for this parameter

5.3.2. Current output scaling
This programming mode is the simple and fast way to modify the scaling of the current output. For changing all parameters other than those assigned to 4 and
20 mA use either the QUICKSET (5.3.2) or the Full Parameter Access (5.3.3). Measuring is going on during programming in accordance with the old parameter
set. New parameter set will be valid after returning to measurement from programming mode! The instructions for this programming can also be found below the
screw cover on the front panel of the EchoTREK.
KEYS OPERATION
ENTER
E
+ UP (press for 3 seconds) Enter into or exit from the current output scaling programming mode
UP / DOWN / NEXT Set value (increase/decrease the blinking digit or scroll up/down) / Move left with the blinking digit
UP + DOWN "GET LEVEL" - display actual level value measured by the EchoTREK
ENTER
E
Save actual value on the screen and move to the next screen
NEXT + UP Quit current output scaling programming mode without saving the modifications (CANCEL)
NEXT + DOWN Display Factory Default of the relevant screen (DEFAULT)
In this programming mode, the display will indicate PROG and the following screens:
SCREENS ACTIONS
4 : xxxx
xxxx – level value assigned to 4 mA current output
Manual: set the level value manually (by using UP / DOWN / NEXT keys) and save it (by ENTER
E
) counted from the
maximum measuring distance (H) which is to be assigned to 4 mA output current
Automatic*:use the “GET LEVEL” function (UP + DOWN ) when the medium inside the tank is at the level what is desired
to be assigned to 4 mA value (“GET LEVEL” functions only works if ECHO LED is lit) and save the displayed value as the above
described
Default value: 0 m (empty tank)
20 : xxxx
xxxx – level value assigned to 20 mA current output
Manual: set the level value manually (by using UP / DOWN / NEXT keys) and save it (by ENTER
E
) counted from the
maximum measuring distance (H) which is to be assigned to 20 mA output current
Automatic*:use the “GET LEVEL” function (UP + DOWN ) when the medium inside the tank is at the level what is desired
to be assigned to 20 mA value (“GET LEVEL” functions only works if ECHO LED is lit) and save the displayed value as the above
described
Default value: Measurement range = XM– Xm(max. measuring distance – max. measuring distance (dead band))
*For the Automatic function the EchoTREK should be set to (LEV) level measurement mode and the ECHO LED should lit.

5.3.3. QUICKSET
RECOMMENDED AS A SIMPLE AND FAST WAY TO START UP ECHOTREK
QUICKSET programming is aided by 8 screens to set the 8 basic parameters of the device if the required application is not a challenging one. The instructions of
this programming mode are also to be found, below the screw cover, on the front panel of the EchoTREK.
KEYS OPERATION
ENTER
E
+ UP (press for 3 seconds) Enter into or exit from the quickset programming mode
UP / DOWN / NEXT Set value (increase/decrease the blinking digit or scroll up/down) / Move left with the blinking digit
UP + DOWN "GET LEVEL" - display actual level value measured by the EchoTREK
ENTER
E
Save actual value on the screen and move to the next screen
NEXT + UP Quit current output scaling programming mode without saving the modifications (CANCEL)
NEXT + DOWN Display Factory Default of the relevant screen (DEFAULT)
In this programming mode, the display will indicate PROG and the following screens:
SCREENS SETTINGS
AP : xxyy
APplication
xx= select “EU” (European) for metric or “US” for US engineering units (Use UP / DOWN keys)
yy= indicating “Li” for liquids or “So” for solids level measurement (can not be changed)
Default value: “EU” metric (European), “So” for solids level measurement
H : xxxx
H = xxxx – maximum distance to be measured – Distance between transducer face and tank/silo bottom
Manual: set the tank height value manually (by using UP / DOWN / NEXT keys) and save it (by ENTER
E
)
Automatic*:use the “GET LEVEL” function (UP + DOWN ) when the tank is empty to obtain the actual measured
distance between the sensor face and the tank bottom (“GET LEVEL” function works only if ECHO LED is lit) and save the
displayed value as the above described
Default value: maximum measuring distance XM, see Technical Data Table
