Fill Level Sensor - ABB i-bus KNX Product Manual

®
ABB i-bus KNX
Parameters
7.11.1.2.1 —
Dependent parameter
Dew point reached when
Options:
This parameter defines how the input reacts if the dew point is evaluated as reached or not reached.
You can also define whether the dew point sensor is a normally closed or normally open contact.
•
Contact open: The dew point is considered reached if the contact is open.
•
Contact closed: The dew point is considered reached if the contact is closed.
7.11.1.2.2 —
Dependent parameter
Send status value
Options:
•
After a change: Sends the value only after a change.
•
After a change and cyclically: Sends the value after a change, and cyclically. Enables the dependent
parameter Send input status cyclically.
7.11.1.3

Fill level sensor

Selecting Fill level sensor uses the input to connect a floating contact that monitors the fill level of
a condensation pan. Select the Via physical device input option in the Fill level sensor parameter on the
Application parameters page to take the status of this input into account in room temperature control.
Without this setting, the input value is sent on the bus but not taken into account in the controller.
If several inputs are set to this option and the controller runs an evaluation, all inputs are internally linked
by an OR operation. This means that as long as one of the contacts is open, the controller responds as
if all of the inputs are open. Once all contacts signal no fill level alarm, the controller evaluates this as no
alarm.
Inputs are scanned after a bus voltage recovery, download or ETS reset. Their current status is sent on
the bus when the sending and switching delay is complete.
