display.
The display is made up from a graphical matrix
with 132 x 64 pixel in order to signal the type of
functi oning, displaying set parameters and any
alarms that have intervened.
All default se� ngs and any modifi cati ons are
memorised in the board.
With the installati on of the PGD1 remote panel,
all of the functi ons and se� ngs available on the
machine can be replicated at a distance.
A� er a power cut, the unit can re-start automati -
cally keeping the original se� ngs.
The user interface is represented by a graphic dis-
play with six keys for navigati on.
The displays are organised via a menu hierarchy,
which can be acti vated by pressing the navigati on
keys. The default for displaying these menus is
represented by the main menu.
Navigati on between the various parameters takes
place using the arrow keys positi oned on the right
side of the panel. These keys are also used to
modify the parameters selected.
