2.4 SI040 - CESVA Sensor Manager Software
CESVA Sensor Manager is the software to verify and set the TA120 noise
sensor. In order to communicate with the sensor, two software applications
should be installed:
1. Install the drivers package with the CESVA USB Drivers software,
version 1.01 or later.
2. Install the CESVA Sensor Manager software.
If you already have an older version of CESVA Sensor Manager or CESVA USB
Driver installed in your computer, first uninstall the old version before installing
the new one.
NOTE: Download the latest versions of CESVA Sensor Manager and CESVA
USB Drivers from (www.cesva.com), you will find these softwares
in the support section of the TA120 sensor. This will ensure you are installing
the latest versions.

Chapter 3 Installing the TA120 sensor 9
3.1 Steps
1. Preferably, mount the sensor vertically using its support and flanges. The
TA120 support also allows the sensor to be mounted horizontally.

10 Chapter 3 Installing the TA120 sensor
2. Unscrew the 4 screws [2] of the front of the sensor box and remove the box
cover.
3. Set TA120 communication for data transmission (see Chapter 4).
4. Feed the TA120 sensor (see Chapter 5).
5. Place the switch POWER [12] in the ON position. Check that the LED [6] has
been turned ON (red). If it is not lit, there is a problem in the power supply: check
the external power and that the switch POWER [12] is in the ON position.
6. Wait 5 minutes and check that the LED SERVER [7] is lit (green). If it is not lit,
there is a problem with the data server or router configuration, AP (Access Point)
or Internet access: MAC address, DHCP enabled, etc. In that case, consult your
installer or router provider or AP.
For TA120 sensor with current loop analog output configuration of 4-20 mA, the
SERVER LED [7] will always be turned off.
If the SERVER LED [7] is lit, the sensor is working properly. Close the sensor
box by the 4 screws [2] of the front cover.

Chapter 3 Installing the TA120 sensor 11
3.2 Cable gland inputs
In the bottom part of the TA120 there are two cable gland inputs [4 and 5] to
introduce the necessary cables for power thesensor andfor communication thereof
if necessary (depending on configuration).
The gland connector has the following elements:
[Cap] [Seal] [Sealing nut]
- Cap to close the cable gland input which will not be use.
- Seal Consisting of two concentric rubber rings to seal the cable introduced by
the cable gland input.
- Sealing nut to close the cable gland input.
Follow these steps to enter the power and / or communication cables in the
corresponding input cable glands:
1) If there is a cap, remove it and then unscrew the sealing nut.
2) Pass the power / communication cable by the corresponding input cable gland.
If the thickness of the cable does not allow to insert the cable, push the Seal
part with a thin and elongated tool by pushing from the inside of the TA120
central body [3].
NOTE: In case that only one of the two inputs cable gland is used, place the
supplied cap on the unused input to maintain IP65 sensor protection.

12 Chapter 3 Installing the TA120 sensor
Once the Seal is out, separate the two concentric rubber rings and insert just
the external rubber ring from the outside of the TA120 central body [3].
→→
3) Insert the cable first trough the sealing nut and then through the input
gland.The cable should not have the connector due the connection between
the cable and its connector will be done after the cable is entered through the
input cable gland.
4) Finally place the respective connectorto the
cable already introduced by the input cable
gland, and plug in the connector on the main
body of sensor TA120.

Chapter 4 TA120 communication for data transmission 13
Depending on the configuration of the acquired model, there are several options
for data transmission:
4.1 Ethernet
To make an Ethernet communication insert the LAN cable without RJ45 connector
through the bottom input cable gland [4], then crimp the cable. See chapter 3.2 for
more information about insert the cable through the appropriate cable gland input.

14 Chapter 4 TA120 communication for data transmission
Connect the LAN cable between the RJ45 [9] connector and the corresponding
router or AP (Access Point). Take care to put the cable in a "U" shape under the
TA120 sensor for, in case of rain, avoid possible water dripping into the box.
Use CESVA Sensor Manager software - SI040 if you need configure the server
where TA120 sensor data will be sent and / or if you want to set a static IP address.
For this, consult the manual or software help.
4.2 Wi-Fi* (WF120 Optional module)
Through the USB output [8] and the SI040–CESVA Sensor Manager software you
should seek the wireless network to connect the TA120 sensor. For this, consult
the manual or software help.
4.3 Modem 3G/GPRS* (MR123 Optional module)
Through the USB [8] CESVA Sensor connection and SI040-software Mananger,
configure the parameters of the internal 3G/GPRS modem of the TA120. For this,
consult the manual or software help.
NOTE: only recommends the use of SIM cards with a flat rate
contract. Other types of cards, for example prepaid, can give problems.
NOTE: recommends the use of SIM cards from telephone
companies that have their own infrastructures near the measurement area of
the TA120 sensor.

Chapter 4 TA120 communication for data transmission 15
4.4 Current Loop 4-20mA* (CL120 Optional module)
Analog output via 4-20mA current loop. Insert the communication cable through
the bottom gland input [4], then connect the cable to the 4-20 mA current loop
connector [10]. See chapter 3.2 for more information about insert the cable through
the appropriate gland input.

16 Chapter 4 TA120 communication for data transmission
4.4.1 Description of a 4-20mA current loop circuit
A typical 4-20mA current-loop circuit is made up by next elements: a sensor
(TA120); a power supply for the loop; and a receiver (to read the information).
These elements are connected in a closed, series circuit, loop.
The sensor output transmits the proportional 4-20mA dc-current that circulates
within the closed series-loop. The 4 mA represents the sensor’s lowest level output,
and 20 mA representing the sensor’s highest level output.
The receiver, normally a data acquisition system, converts the 4-20mA current back
into a voltage which can be further processed and/or displayed.
Current loops are ideal for data transmission because of their inherent insensitivity
to electrical noise. In a 4-20 mA current loop, all the current flows through all
components.

Chapter 5 TA120 sensor power 17
Depending on the purchased model configuration, there are several options to
power the TA120 sensor:
5.1 Mains
Connect the power cable to the mains (make sure it meets the specifications
described in section 8.9). Take care to put the cable in a "U" shape under the
sensor, in case of rain, this will avoid possible water dripping into the box. Refer to
Section 3.2 for more information about insert the cable through the appropriate
gland input.
Connect the power cable to the A.C. INPUT [16] of the TA120 sensor.
The power cable must always respect the following cable connections:
•Brown wire Phase ➔L
•Yellow and green wire Ground ➔
•Blue wire Neutral ➔N
➔
In the same TA120 sensor cover [18] the equivalence of each of the three input
connectors of the AC INPUT are indicated.
