Menu navigation
4 keys are used for navigating the menus and submenus and
for changing parameters and confirming choices.
Their function depends on the context and on how long they
are pressed.
The LEDs above the keys not only give confirmation
that each key has been pressed (by flashing), but
also show which keys can be used in each situa-
tion.
The navigation functions assigned to the keys are:
At first power-on, scrolls the fast configuration
menu; otherwise, the user configuration menu
(Alarm limits, etc.).
Each time you press the key, the value of the
displayed parameter is confirmed and you go to the
next menu item.
Keep the key pressed for more than 2 seconds to
enter the Programming/Configuration menu.
Each time you press the key, you return to the pre-
R
vious menu item or to the higher menu level, as ap-
propriate.

Displays
The indicators have 2 or 3 displays, depending on the model.
The Main menu shows:
•
PV display: value of process variable.
•
SV display: value of parameter (Alarm 1 limit).
•
F Display (models 1250 L only): value of control output
(if parameter dS.F = OUT.PW).
On models 1250 L, the percentage value of the control
output is also shown graphically on a bargraph.
According to the situation (programming, alarm, etc.), the
indicator displays can show other information, such as the
name of the parameter, description of the parameter, diagno-
stics messages and alarm messages.
Attention! The displays show only the parameters
and menus for a defined configuration.
3.1.2.1.
Display characters
The displays reproduce the various characters by combining
7 or 14 segments.
The following tables show the shape of the various cha-
racters.
