2. Introduction

Ultrasound Controller

Ultrasound Controller uses ultrasound to make measurements of liquids. It can detect bubbles in

flowing liquid or it can detect presence of liquid behind a container wall or it can measure

continuous liquid level. The Ultrasound Controller has four different modes of operation:

Air Sensor mode: The Air Sensor monitors the presence of gas or particles in flowing liquid. The

Air Sensor is very reliable and easy to use. Two Air Sensors can be connected to one

Ultrasound Controller.

Level Switch mode: The Level Switch is a small sensor which attached to the outside of the

container can sense the presence of liquid inside the container without making hole in the

container. Four Level Switches can be connected to one Ultrasound Controller.

Level Sensor mode: Continuous liquid level is measured with a Level Switch attached under the

container bottom (no hole in the container). High accuracy is achieved with a second Level

Switch measuring liquid sound velocity. Two levels can be measured with one Ultrasound

Controller.

Gel Distance Sensor mode: Continuous gel distance is measured with a Gel Distance Sensor.

This mode is only available in GS72.

Gel Sensor mode: Gel Sensor GF90 installed inside or Level Switches attached outside the

container can sense the presence of gel in the container. Four gel sensors can be

connected to one Ultrasound Controller.

The software version of the Ultrasound Controller is shown briefly on the display when power is

switched on. The software version can also be found in the HELP-menu. Software versions may

differ slightly and therefore it is usually better to use a manual version corresponding to the

software version, even though a later manual version can have less errors.

Installing Ultrasound Controller D72, G72

The Ultrasound Controller should be protected from dust and

water. It is made to be attached to a DIN-rail, to which it

snaps easily and can be removed by pushing up and bending

the top out. Usually it is installed in an electric cabinet. The

connector terminals can be removed by pulling the connector

straight out. Connections for terminal 1-7 and D-sub, see

table. Connections for terminal 8-17 depend on the selected

mode, see table in the corresponding chapter.

The Ultrasound Controller should be installed in accordance

with national regulations. A person with

the required knowledge should

perform the installation.

Installing Ultrasound Controller DP72, GP72

The Ultrasound Controller DP72 and GP72 should be protected

from dust and water. It is made to be attached to a DIN-rail, to

which it snaps easily and can be removed by pushing up and

bending the top out. Usually it is installed in an electric cabinet.

The green connector terminals can be removed by pulling the

connector out. Connections for terminal 1-7 and D-sub, see

table. Connections for terminal 8-17 depend on the selected

mode, see table in the corresponding chapter.

The Ultrasound Controller should be installed in accordance

with national regulations. A person with the required knowledge

should perform the installation.

Installing Ultrasound Controller D128, G128

The Ultrasound Controller D128 and G128 is protected

according to IP65 and can be installed outside a protecting

cabinet. The bottom plate must be removed in order to access

the terminals. Remove dummy covering and insert cable

glands as needed. There are 3 small and 4 big cable glands.

There should be only one cable in each cable gland to achieve

full IP65 protection. The pressure compensation element can

be moved to different place but must not be removed

completely. Make sure the gasket is in place when screwing

the bottom plate. Connections for terminal 1-10, see table.

Connections for terminal 11-20 depend on the selected mode,

see table in the corresponding chapter.

The Ultrasound Controller should be installed in accordance

with national regulations. A person with the required knowledge

should perform the installation.

Keep MENU-button pressed to scroll continuously. Press also BACK-button while pressing

MENU-button to scroll backwards. Menu-text, parameter-names and parameter-values as seen on

the display is here in the manual written in blue italic.

Sensor MODE and the start-screen

When power is applied to the Ultrasound Controller it displays the software version on the LCD-

display, followed by the start-screen. Depending on which mode is set; the corresponding start-

screen will be shown. The Ultrasound Controller can be set to either Air Sensor mode, Level

Switch mode, Level Sensor mode or Gel Sensor mode. When the Ultrasound Controller is

powered on for the first time Set sensor MODE is displayed. Press the MENU-button to scroll to the

desired mode and press the SELECT-button to select it. Sensor mode can be changed again in

ADVANCED SETTINGS. Here is a map of the menu-system:

4. Electric Noise

Ground Connection and Sensor Cable

All sensor cables must be shielded. The unshielded part of the

sensor cable should be maximum 40mm. The sensor cable may not

be extended.

Best connection to ground is achieved by using grounded cable

glands on the sensor cables. Only if the sensor cable is not grounded

via the cable gland, is it recommended to connect terminal 16 on the

D72, DP72, G72, GP72, GS72 or terminal 19 on D128, G128 to

ground, near the transmitter as shown in the picture.

Electric noise, with frequency around 2 MHz, entering the sensor

cable can cause measurement problems and is better to be minimized by using shielded cables

and by not routing the sensor cables along high voltage cables connected to a variable frequency

drive.

Noise from Variable Frequency Drives

Variable frequency drives produces noise which exist mainly in the cable connecting the variable

frequency drive to the motor. It is good if this cable is shielded and not routed along the sensor

cables. The variable frequency drive also produces ground current noise, caused by noise

travelling capacitively to ground inside the motor. To reduce

such ground current, a common mode filter can be used. The

most simple common mode filter is a ferrite clamp, clamped on

the three wires coming out of the variable frequency drive. An

even more efficient filter is a toroid. It consist of a ferrite toroid

with the three wires, connected to the 3-phase output of the

variable frequency drive, threaded through the toroid as shown

in the picture.

The filter in the picture is very good and is made of two ferrite

toroids. The three wires are wound three times through the

toroid. The ground wire do not go through the toroid.

Ferroxcube toroid TN25/15/10-3F3 is suitable for wires up to

2,5mm2and it is shown in the picture. Alternatively, EPCOS

toroid B64290L616X830 can be used. If the wires do not fit, a

larger toroid can be used. Ferroxcube toroid of material 3F3 or

EPCOS toroid of material N30 or Amidon toroid of material 77

are suitable for filtering frequencies around 2MHz.

5. Ex-installation with ex-barriers

Ex-barriers are not shielded so if ex-barriers are

used, Ex-barrier shields must be inserted on

each side of the group of EX-barriers connected

to each Ultrasound Controller (see picture). The

ex-barrier connects the sensor cable shield to

ground which makes it possible for ground

currents to enter. Because of this, minimizing

ground currents is very important especially

when EX-barriers are used.
