through a digital input (DIF.2706). To send the command, it is necessary to write in
sequence (within 5 seconds):
▪
HOLDING REGISTER 101: write the password configured with the parameter
P.0004.
▪
HOLDING REGI
STER 102: write value “52”. This command also silences the
horn, if active.
When the anomaly has been acknowledged, it stops flashing on page S.02 ANOMALIES.
Once acknowledged, if it is only a warning, it is automatically cancelled, if the cause that
triggered it is no longer present.
Instead, if the cause disappears before the anomaly is acknowledged, the same will remain
on the display.
10.3
An anomaly can be cancelled only when the cause that activated it is no more present.
The controller automatically resets all the acknowledged warnings when their cause is no
longer active.
On the contrary, to cancel discharges and shut-downs, it is necessary to follow one of the
below procedures:

By putting the controller in OFF/RESET mode.

Using a modbus command via USB. The commands can be protected by a password
(P.0004) which has to be sent before any command, and can be deactivated through
a digital input (DIF.2706). To send the command, it is necessary to write in sequence
(within 5 seconds):
▪
HOLDING REGISTER 101: write the password configured with the parameter
P.0004.
▪ HOLDING REGISTER 102: write value “53”.

Using a digital input configured with the feature DIF.2001 -
“Alarms reset command”.
When the input becomes active, the controller executes a reset of all anomalies.
10.4
All anomalies are being recorded (each with its own code) in the events log.
There are some features available for configuring the digital outputs related to anomalies:

DOF.3151
(“reset of anomalies”). The board activates this output for one second when the
internal sequence for the cancellation of anomalies is carried out. With this procedure, it
is also possible to reset externally managed anomalies.

DOF.3152 (
“external horn”). This output is activated and deactivated along with the
internal hooter. It can be used to control a more powerful hooter and/or a lamp.

DOF.4001 -
(“Warnings”). The output is “active” if there is at least one pre-alarm.

DOF.4003: the output will be activated if at least a deactivation is active.

DOF.4004: the output will be activated if at least a shut-down is active.

DOF.4005: the output will be activated if at least a block or a deactivation are active.

DOF.4031: the output will be activated if at least an anomaly linked to the generator is
active.

DOF.4032: the output will be activated if at least an anomaly linked to the engine is active.

DOF.4034: the output will be activated if at least an anomaly linked to the fuel is active.
