
DOF.4035: the output will be activated if at least an anomaly linked to switches is active.
In addition, the controller makes available the anomalies statuses for the AND/OR logics by
means of the following internal statuses:

ST.008 - "Pre-alarm cumulative"

ST.010 - "Deactivations cumulative"

ST.011 - "Interlocks cumulative"

ST.012 - "Unacknowledged warnings cumulative"

ST.014 - "Unacknowledged deactivations cumulative"

ST.015 - "Unacknowledged interlocks cumulative"

Every digital input of the controller can be used to activate anomalies. These anomalies are
divided into two kinds:
•
Specifics . They are configured with functions DIF.4201 and following. The controller
knows the way these anomalies have to be managed and has already error symbols
(not configurable) related to each anomaly.
•
Generic. They are configured with functions from DIF.4001 to DIF.4064. For
these
anomalies, the controller will show the generic symbol:
Also, using the suitable functions, the controller can be taught on how to manage the
anomaly.
The specific anomalies will be described in the following paragraphs: in the description we will
always refer to the parameters related to the digital input
T.16 of the controller (P.2001 and
P.2002). In doc [1] there is a table showing the parameters to be used for each digital input.
What stated above is true also for generic anomalies. They will not be described in the
following paragraphs, because they will be infinite repetitions of the same description for each
input. They are described here instead, mentioning the parameters for input
T.16 of the
controller.
The controller assigns the numeric codes from 701 to 742 to the generic anomalies related to
the digital inputs (docs [1] contain a table showing the code per each input). Using the
parameter which configures the function (P.2001), it is possible to select the type of anomaly
(warning, deactivation or block) and also to define the conditions in which the anomaly has to
be managed.
ATTENTION!: by se
tting the delay to “0”, the acquisition of the anomaly is
disabled .
In the following list the functions for the configuration of digital inputs used to manage the
generic anomalies are listed. They are grouped four by four: the four functions for each group
define the type of anomaly (see documents e [1] for the list of functions).

DIF.4001 , DIF.4003 , DIF.4004 . The board will activate this anomaly if the digital
input is uninterruptedly active for the configured (P.2002) time span.

DIF.4011 , DIF.4013 , DIF.4014 . The anomaly can be activated only if the engine has
been started by controller, and if it is in motion from, at least, the time span configured
in P.0216
(“engine protection masking time”). The board will activate this anomaly if
the digital input is uninterruptedly active for the configured (P.2002) time span.
