BARGRAPH DESCRIPTION

This device includes two 33 LED’s bargraphs indicators.

On the right bargraph, with orange LED’s, it is possible to show:
- the operative set point scaled as configured by “brG.L” [C.I03]

and “brG.H” [C.I04]; the “SP” LED, located on the base of the
bargraph, is lighted.
If the operative set point is out of the range scaled, the first or
the last LED's will flash.

- the power output value; the “%” LED, located on the top of

the bargraph, is lighted.
When the device has two process outputs, the central LED
(which is a two-colored LED) becomes green.
It divides the bargraph into two parts: the MAIN process
output is shown on the upper part while the SECONDARY
process output is shown on the lower part.

On the left bargraph, with green LED’s, it is possible to show:
- the process variable scaled as configured by “brG.L” [C.I03]

and “brG.H” [C.I04]; the “PV” LED, located on the base of the
bargraph, is lighted.

- The deviation error (PV - SP) with resolution configured at “brG.d”

[C.I05]; the “DEV” LED, located on the top of the bargraph, is
lighted.
