Prompts the page S.02 on the multifunction display. This page shows the fault numeric
code and the symbol related to the anomaly.
The numeric code flashes to indicate
that the anomaly hasn't been recognized by the operator yet.
It activates the flashing of the “ALARM” indicator light, if the anomaly belongs to the
pre-alarm category, or it turns it on if the anomaly belongs to the category of
discharges, deactivations or interlocks.
If the anomaly is not a warning, the controller disconnects the generator from the load
and stops the engine (with or without the cooling cycle).
Three operations can be carried out on an anomaly:
Silence
the horn.
Acknowledge
anomaly: means informing the controller that the operator
has taken note of it.
Reset
: this tells the controller to act as if the anomaly was never active.
10.1
The operator can silence the horn:
By pressing any button on controller panel.
This operation also acknowledges the
anomaly, which stops flashing on the display.
.
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 REG
ISTER 102: write value “51”.
Parameter P.0491 (Horn duration) influences the management of the controller's horn.
If set to zero, the horn will be never activated.
If set to 999, the horn will be activated when a new anomaly arises, and will be
deactivated with the above mentioned procedure.
If the hooter is set on a value between 1 and 998, it will be activated when a new
anomaly arises and deactivated through the described procedure above, or when the
configured time span has elapsed.
Silencing the horn is not the same as acknowledging the anomaly: in fact, it continues to flash
on page S.02.
10.2
The operator can “acknowledge” the anomaly (sequence ISA2C) in two ways:
By pressing any button on controller panel.
If you press any button with siren on,
it also stops even the siren
.
By using a command from the serial port. The commands can be protected by a
password (P.0004) which has to be sent before any command, and can be deactivated
