•
Pressure sensor maximum pressure: displays the maximum value in the external pressure
sensor range. Value expressed in the unit of measure setted in the UVIX
menù “Unit of
measure preference”
.
The maximum pressure value regulated directly by the PRE series regulator is 150 PSI, a limit
determined by its internal components. To regulate higher pressure values, an external pressure
amplification system must be provided.

External sensor configuration - examples
-
External sensor with measured pressure range 0-100 PSI, output signal 0,5-4,5V:
o
Pressure sensor minimum pressure = 0 PSI
o
Pressure sensor maximum pressure = 100 PSI
o
External sensor interface = Voltage
o
Minimum external sensor output = 0,5
o
Maximum external sensor output = 4,5
-
External sensor with measured pressure range 0-10 bar, output signal 4-20mA:
o
Pressure sensor minimum pressure = 0 bar
o
Pressure sensor maximum pressure = 10 bar
o
External sensor interface = Current
o
Minimum external sensor output = 4
o
Maximum external sensor output = 20
-
External sensor with measured pressure range 0-300 bar, output signal 0-10V:
o
Pressure sensor minimum pressure = 0 PSI
o
Pressure sensor maximum pressure = 300 bar
o
External sensor interface = Voltage
o
Minimum external sensor output = 0
o
Maximum external sensor output = 10

Use
•
Ensure that the pressure in the compressed air supply system and all other operating conditions
remain within the admissible values.
•
Use with liquids or gas is not permitted according to the intended use
•
The LED bar on the regulator provides information regarding the status of the product, please
refer to the table below.

STATUS
DESCRIPTION
LED OFF
LED is OFF.
LED ON
LED is fixed ON.
BLINKING
LED is blinking according to a specific sequence associated to the different diagnostic
state: @XX [ms/Hz] per YY [s]
▪
XX is the ON/OFF time duration of a blink.
▪
YY is the repetition time of blinking sequence.
Example 1
: 1 blink @100 ms every 2 s
