•
By using a command from the communication ports. To send the command you need
to write in sequence (within 5 seconds):
o
HOLDING REGISTER 101: enter the password configured with the parameter
P.0004.
o
HOLDING REGISTER 102: enter the 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 when the operator presses the ACK button.
•
If set to a value between 1 and 998, the horn will be activated when a new anomaly
arises and will be deactivated when pressing the ACK button, or after P.0491 seconds
from activation.
Silencing the horn is not the same as acknowledging the anomaly: in fact, it continues to flash
on page S.02 ANOMALIES.
The operator
can “acknowledge” the anomaly in three ways:
•
By pressing the ACK/ENTER button.
•
Using a digital input configured with the feature DIF.2002 -
“Command for alarm
acknowledgment”. When the input becomes active, the controller executes an
acknowledge of all anomalies.
•
By using a command from the communication ports. To send the command you need
to write in sequence (within 5 seconds):
o
HOLDING REGISTER 101: enter the password configured with the parameter
P.0004.
o
HOLDING REGISTER
102: enter the value “52”.
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.
When the controller performs an anomaly acknowledgement, it also activates for one
second the outputs configured with the function DOF.3154 -
“Acknowledge of the
anomal
ies”.
This helps in using the acknowledge command of the controller for
acknowledging alarms on external devices.
The operator can “reset” the anomaly in four ways:
•
By putting the controller in OFF/RESET mode.
•
By pressing the buttons SHIFT + ACK/ENTER.
•
By using a command from the communication ports. To send the command you need
to write in sequence (within 5 seconds):
o
HOLDING REGISTER 101: enter the password configured with the parameter
P.0004.
