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.

Mounting
PressureBox must be mounted on a firm non-vibrating surface by use of screws through the holes in the
mounting base on each side of the PressureBox.
Please also pay attention to the paragraph with safety precautions and preconditions for mounting and

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.
