Position Indication - Vexve Hydrox HCU Remote Installation, Operation And Maintenance Instructions

5.2.7. Position indication

In a similar manner to valve control, position indication is addressed in the same way via different UI's.
Figure 6 shows a generic view that will be available to the user for both local and remote (WebApp) visu-
alization.

Table 6. Valve indicators
Valve indication can be observed mainly from elements 1 and 2. These elements show the percentage
of valve opening as well as visually represent an approximation of the current position of the valve. The
open/closed indicators in element 3 light up when the valve reaches its end position. The other elements
show other relevant values of the valve during operation. These values are addressed in more detail in
other sections of this document. Digital signals are used to stop the opening/closing cycle. The analogue
position signal (4-20mA) is used for indicating the continuous position of the valve.
