CoilVision
With the integrated CoilVision technology the proportional regulator is able to
constantly monitor the operation of the coils inside it and prevent any malfunctions.
Depending on the model chosen, the proportional regulator can have three different levels of
diagnostics:
•
Without diagnosticc: the CoilVision technology isn’t implemented.
•
Basic diagnostics: CoilVision technology is active and will advice the user when the coils are
nearing the end of their life cycle
•
CoilVision diagnostics: CoilVision technology is active and, in addition to advice the user
when the coils are nearing the end of their life cycle, constantly sends information about
their current health status to the UVIX environment.

Digital output
The digital output (OUT signal, pin 8) is a 0-24V digital signal. Through the UVIX configuration
software it is possible to set the logic of this output:
•
Active
–
high level: if the output is activated, its value is brought to a high logic level.
•
Active
–
low level: if the output is activated, its value is brought to a low logic level.
Furthermore, based on the electrical connection made by the user, the following configurations
can be obtained:
•
PNP: in this configuration the output signal refers to GND (pin 2), therefore the PNP digital
input of the control system must be connected between pin 8 (OUT) and pin 2 (GND).
•
NPN: in this configuration the output signal refers to + 24V (pin 1), therefore the NPN digital
input of the control system must be connected between pin 8 (OUT) and pin 1 (+ 24V)
The operating mode of the digital output depends on what code is ordered. There are three
different operating modes:
•
Error: the digital output changes state if the Regulator detects an error.
•
Switch pressure: with this operating mode it is possible to set two fixed pressure thresholds,
a lower one and a higher one. The digital output changes state if the regulated pressure is
outside the range delimited by the two thresholds set. This is a useful way to check whether
the regulated pressure lies within the preset pressure range.
