whereas, as regards the VITAL FAULTS, you can only leave the
diagnostic sub-menu, if the device allows you to do that, by
entering the “settings change” menu.
2) Inhibited device
The condition of “inhibited device” is displayed as follows:
[FAULT <!>]
[..............P ]
This condition can only be reset by entering the "settings
change“ menu (it is however necessary to confirm when you
are prompted to SAVE CHANGES, although no setting has
been changed).
Warning: even simply view the set parameters from the
“settings change” menu, since upon leaving this condition, the
device will not be inhibited any longer.
If, beside inhibiting the device, you have also deconfigured it,
the return to operation causes a fault K message to be
displayed until the unit is configured anew (see paragraph
4.14).
6.2 MAIN SETTING CHANGE MENU
By pressing the key
anywhere in the display menus
for at least 2s, the main settings change menu is entered.
Thence, several sub-menus can be entered (tree- structure).
When the settings change function is enabled, the green LED
(RUN) lights up blinking.
If the settings change menu is already acceded through a PC
or a network, any local change is inhibited, and the following
message will be displayed:
[SETTINGS CHANGE]
[NOT AVAILABLE ]
The access priority to the changing function among PC, net-
work and keyboard is time-dependent.
During the settings change operations, the device continues
working with the old settings.
All the displays can be made permanent.

By pressing the
key anywhere in the changing
menus for at least 2 seconds, you go back to the main display
menu, but you are first prompted to confirm or discard the
changes made:
[NEW
SET.CONFIRM?]
[< NO YES >]
By pressing
ï
all the changes made are discarded, whereas
by pressing
ð
the changes made are confirmed.
The green LED (RUN) stops blinking and becomes perma-
nent.
If upon confirming the changes, a fault is detected, the settings
are not accepted as long as the fault event persists. This state
is signalled for 3s by the following message:
[SETTINGS
CHANGE]
[DELAYED ]
once the event is over, you are prompted to confirm the
changes made again.
If the transfer is interrupted is due to a digital input being
enabled which cannot be disabled at the moment and you
need to change the settings, the device must be inhibited; after
that, you can start changing the settings (see paragraphs 4.14
and 6.1.13).
Note: the “change settings” function can even be implemented
when the device is “forced” to use the SPARE SETTINGS. In
such a case, the system only interrupts the selection of
SETTINGS IN USE: MAIN until the external forcing signal
disappears. If a setting is changed when the system is “forced”
from the outside, the following message is displayed:
[SPARE SETTINGS]
[FROM EXT.CONTROL]
All the following examples take their start from the main
settings change menu.
