PressureBox has 3 different areas of usage
1. Only showing the measured value
2. As external transducer in installations
3. As regulator with build-in transducer
PressureBox is available in 4 major pressure areas which can be scaled
0-7000Pa - can be scaled to 0-5000Pa, 0-3000Pa or 0-2000Pa
0-2500Pa - can be scaled to 0-1500Pa, 0-500Pa or 0-250Pa
0-500Pa - can be scaled to 0-250Pa, 0-125Pa or 0-50Pa
0-50Pa - cannot be scaled
Each of the major pressure area models are also available in the variants
1 or 2 build-in pressure transduceres
With or without display
More PressureBox models have the possibility for connecting 2 temperature sensors of type NTC or
PT1000
For all models signal output can be chosen to be ModBus or 0-10V / 4-20mA.
Please also refer to model overview on page 5.

Setting Pressure Area in PressureBox without Display
To use PressureBox as a pressure transducer in installations using 0-10V or 4-20mA signal it is possible
to set most models of PressureBox to 1 of 4 different pressure areas. Please refer to table of
PressureBox models to select the right model to the required pressure area.
Below instruction shows how to change the pressure area.
Turn screws and remove lid from PressureBox. Now you
have access to the push buttons and the connection
clamps.
Connect supply voltage.
Hold button 1 down until the green LED is constantly lit.
Let go of button 1.
Push button 1 the number of times required for the
desired pressure area. E.g. for PressureBox E 500; 1
time for 0-50Pa, twice for 0-125Pa, 3 times for 0-250Pa
and 4 time for getting back to factory setting 0-500Pa.
When no buttons have been pushed for 25 sec. the
PressureBox saves the selected pressure area and is
ready to be used as pressure transducer, where pressure
is read as 0-10V or 4-20mA signal through the analogue
output.
The green LED flashes the number of times you have
pushed button 1 and thereby indicate the setting. 3
flashes followed by pause, then again 3 flashes indicates
a setting of 0-250Pa.
If you want to read the pressure though ModBus you must also set the Pressure Area using ModBus
Protocol.
Please see the paragraph on setting up PressureBox using ModBus Protocol.

Further Settings of PressureBox Without Display
If PressureBox without display is to be used in installations where K-factor, setpoints to PID-regulator
etc. are to be used, it must be set using the ModBus protocol.
Please refer to the tables starting at page 12 with ModBus Protocol settings for PressureBox.
Setting PressureBox With Display
To use PressureBox as a pressure transducer in installations using 0-10V or 4-20mA signal it is possible
to set most models of PressureBox to 1 of 4 different pressure areas. See table of PressureBox models
for the different models possible pressure areas.
Below instruction shows how to change the pressure area.
Turn screws and remove lid from PressureBox. Now you
have access to the push buttons and the connection
clamps.
Connect supply voltage.
Hold down button 1 for approx. 15 sec. until display
changes to show 'SCALEMAX' and the current pressure
scale setting is shown.
Let go of button 1
Push button 1, with each push the scale value changes
in display. Stop when required scale is shown.
Page 10 of 17
When the required scale value is shown in display, push
button 2 to save the setting.
PressureBox is now ready to be used as pressure
transducer, where pressure can be read as 0-10V or 4-
20mA signal through the analogue output.

Setting up PressureBox with Display Using the Menu Setting
To get to the PressureBox with display setting menu
push button 2 is held down for 3 sec. until 01.SET1
shows in display. Then let go of button 2.
Now push button 2 making first digit flash. Now the first
digit can be changed to value between 0-9 by pushing
button 1. Value of digit changes by 1 for each push.
When required number for the first digit is reached,
press button 2 to go to next digit, which starts to flash.
Repeat this procedure until all digits have the required
value. When pushing button 2 after last digit is set, then
setpoint value 1 is set.
To set up another menu item just push button 1 to go
through the menu items. When getting to the required
item repeat procedure of pushing button 2 first and then
button 1 until required value is shown. Save by pushing
button 2 at the end.
E.g. Menu item 23.ALTID (ALarm TIme Delay). When
menu item is shown in display, push button 2 to set the
value.
Then push button 1 until required value is displayed.
When required value is displayed, push button 2 to save
value. You may now go through the menu items by
pushing button 1.
Menu item 26.EXIT: by pushing button 2 all settings are
saved and PressureBox will work as set up and returns
to displaying current data points.
If no buttons are pushed for 25sec. PressureBox saves
the entered settings, leave the setting menu and turn off
background light.
For PressureBox with display you can activate the PID Regulator and alarm function and alter various
data / setpoints using the push buttons under the lid. The Menu settings and values are shown in the
display and can be altered by pushing button 1 and 2 in turns as described below..
An overview of the menu items, their usage, possible settings and factory settings are to be found on
next page.

Functionality
PressureBox can be used as a very simple transducer, which only measure pressure and display it in
either display or ModBus. It can also be used as an external sensor which sends the measured
pressure to an external controller through 0-10V, 4-20mA output or ModBus. Finally PressureBox can
function as a controller with build-in transducer. The required functionality is chosen either in menu item
03:MODE or ModBus address 4x0002. Refer to below table for description of chosen parameter
according to function.
Page 12 of 17
Value
Description
OFF=Pa
Current pressure is displayed in Pa in display or ModBus.
OFF=l/s
Current value for liter air per second is displayed in display or ModBus. To get
the correct value the K-factor value of the used pipes must be entered in
menu item 04.K VAL or ModBus address 4x0003 and 4x0004.
OFF=m3h
Current value for m3 air per hour is displayed in display or ModBus. To get
the correct value the K-factor value of the used pipes must be entered in
menu item 04.K VAL or ModBus address 4x0003 and 4x0004.
NONE=Pa
Current pressure is displayed in Pa in display or ModBus. And is sent as
regulation signal 0-10V, 4-20mA or via Modbus to external controller. 0-10V or
4-20mA is chosen on juper 4. See jumper setting.
NONE=l/s
As OFF=l/s. Besides regulation signal is sent as 0-10V, 4-20mA or via
Modbus to external controller. 0-10V or 4-20mA is chosen on jumper 4. See
jumper setting..
NONE=m3h
As OFF=l/s. Besides regulation signal is sent as 0-10V, 4-20mA or via
Modbus to external controller. 0-10V or 4-20mA is chosen on jumper 4. See
jumper setting..
PID=Pa
PressureBox functions as controller based on pressure measured in Pascal.
PID=l/s
PressureBox functions as controller based on measured liter air per second.
To regulate properly the K-factor value of the used pipes must be entered in
menu item 04.K VAL or ModBus address 4x0003 and 4x0004.
PID=m3h
PressureBox functions as controller based on measured m3 air per hour. To
regulate properly the K-factor value of the used pipes must be entered in
menu item 04.K VAL or ModBus address 4x0003 and 4x0004.
PressureBox is also equipped with a build-in Alarm function, where minimum and maximum values for
alarm can be entered. As the alarm function sets a data point to 1 at alarm, the Pressure is, when
connected to our gateway-solution, able to send alarmmessages on e.g. a mobile phone.
