If present, the display provides the following information
Area 1 - Display of the measured pressure by external sensor or a warning / error code. If the
unit of measure is setted as Kpa and the maximum value of the regulated pressure exceed
9999 Kpa, the value of measured pressure by external sensor is showed on LCD reduced by a
factor 1/10.
Area 2 - Display of the unit of measurement of the regulated pressure
Area 3
–
Indication of "Digital output active"
Area 4 - The target value of the regulated pressure is set via the analog input
Area 5 - The target value of the regulated pressure is set by a command from the UVIX
software supervisor
Area 6 - Indication of which parameter setting is used for regulation
Area 7
–
Set of regulated pressure range.
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).
