The LCD display and the 3 function keys, if present, show the device status (for example
pressure set and / or any warnings or errors) and to configure some parameters. These same
parameters can also be configured using the UVIX supervision software.
When a time-out expires, the display shows the main screen and at the end of another time-
out, settable with the default value of 2 minutes, the LED-backlit LCD display and the backlit
function keys are switched off. To switch them on again, just press any key.
When one or more warnings appear during operation, the display shows the one with the
lowest number and the LED on the regulator turns yellow.
If there is only one warning and the conditions that caused it are subsequently resolved, the
LED turns green and the LCD display continues to indicate the number of the warning.
By pressing any key, the display will return to indicate the value of the regulated pressure.
If, on the other hand, there are several warnings, the display will show the one with the lowest
number. If only the conditions that caused the warning that is displayed on the LCD screen are
resolved, the LED remains yellow and the LCD display continues to indicate the number of the
warning. By pressing any key, the display will switch to indicate the number of the warning
that is still active.
The following parameters are settable via LCD:
•
Unit of measurement: serves to set the unit of measurement of the Regulator (kPa, psi or
bar).
•
PID mode: serves to set the parameters for the PID behavior; choice between Set1 (slow),
Set2 (medium) or Set3 (fast).
•
Input type: serves to set the source of the pressure target between Automatic or Manual.
•
Minimum and maximum values for regulated pressure range
