2.1 Product description
Sensopress LCD is a measuring and high-tech electronic level controller that can be used in sandy
drinkable waters, in liquid food products or if availing oneself with an adequate plant design, it can
also be used in filthy waters or corrosive liquids.
The measurement is committed by a very perceptible pressure sensor. Its signal once transformed
and elaborated by a microcontroller is converted in “height of water column” measured in water cm.
Note: all the visualized values are in mBar. The correct value in water cm is obtained by augmenting
the pressure in mBar of 2 % (1.973 % a 4°C).
Sensopress LCD can be produced in two versions: with a single output or with 4 outputs in the
multichannel version.
Sensopress LCD is a device which allows to start a relay ( 4 relays in the multichannel version) in
function of differential threshold levels set-up in the data storage by the user.
2.2 Advantages and Benefits
Thanks to its LCD display in which they are visualised all the information concerning the device
and to the three function keys with which it is possible to interact so that to change the parameters,
Sensopress LCD can be easily used.
Sensopress LCD in the multichannel version, by using just a sensor, allows to supervise the start of
4 relays in function of 4 different differential threshold set-up by the user.
2.3 Operating Conditions
• Room-temperature: between +5°C and +40°C
• Maximum relative Humidity: 50% to +40°C (no condensation)
• Sensopress LCD must be installed in locations protected from bad weather and frost.
• The Sensopress LCD sensor can be used in waters free of chemically aggressive substances
(ph 5÷9)
• Sensopress LCD sensor cannot be used with abrasive liquids, solid fibrous substances,
flammable explosive or aggressive liquids.

3 INSTALLATION
3.1 Electrical Connection
Below the diagrams of the electric connection for the two versions, the one with 1 output and other
with 4 outputs.
• Avoid places where it can be possible the formation of condensation.
• Avoid places where the temperature can decrease under (0°C).
The device is provided with a terminal to which is possible to connect the Sensopress LCD supply
wires and also the connecting sensor’s wires and those of the relay’s output.
ATTENTION:
All the inner parts of the device are on electricity grid. In case of a contact can bring to death.
All installation and maintenance work must be performed by qualified personnel with proper
tools!
The staff must use appropriate safety devices. In case of failure, disconnect or turn off the power
supply.
Safety devices :
− Ground protection
− Use an automatic residual-current device

4 OPERATION AND USE
With Sensopress LCD, is possible the managing of a differential threshold for the liquid control (4
differential threshold with the multi-channel version).
After having accomplished accurately the electric installation is possible to proceed with the starting of
the device.
Sensopress LCD has a liquid crystal display in which is possible to visualize all the informations
concerning the device. It has also three buttons with which is possible to interact and change the
parameters. With these is possible to determine the intervention points in which to start or to turn off a
control relay (4 in the multi-channel version), of any other power device (pump, engine), or warning
device (lights, alarm, etc) which have compatible features with those of the device’s relay (relays in the
multi-channel version) of the device (look at next table).

In the single output version the relay turns on in function of the set differential threshold levels. The
relay turns on when the liquid reaches the high threshold and it turns off when the liquid while
decreasing reaches the low threshold.
In the multichannel version we have 4 relays available which can manage 4 different and indipendent
differential thresholds. The relays turn on when the liquid reaches the threshold level set up for that
channel and they turn off when the liquid decreases to the set up low threshold level, always related to
that channel.
There is the possibility to disable the relays of the channel one does not want to use. The relay of the
disabled channel does not commute, regardless of the threshold levels.

4.2 Visualization Menu
4.2.1 Auto Mode
Just after the initial frame the device shows the frame corresponding to the AUTO Mode.
The auto mode shows, how it is indicated in Figure 4, the following parameters:
• The chosen channel (in the single output version is only CH:1)
• The relay’s state corresponding to the chosen channel is specified on the display (on: |; off:
o). In Figure 4 the relay is on.
• The measure in centimetres of the liquid’s level. (274 cm in Figure 4).
• The low intervention’s threshold referred to the chosen channel and specified on the display.
In Figure 4, the low threshold for channel 1 is 99 cm .
• The high intervention threshold referred to the chosen channel and indicated on the display.
In Figure 4 the high threshold for channel 1 is 301 cm.
Figure 4
In the AUTO mode the function buttons Yes/+, No/- are not turned on
By pushing the Menu button it is possible to watch the current mode and the request of transfer to
other modes, how is specified in the example of Figure 5.
