Fill level sensor
Selecting
Fill level sensor
uses the input to connect a floating contact that monitors the fill level of a
condensation pan. Selecting
Fill level sensor
,
Via physical device input
on the
Application
parameters
page takes 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.
Note
If several inputs are set to this option and the controller runs an evaluation, all inputs are inter-
nally linked by an OR operation. This means that as long as one of the contacts is open, the con-
troller responds as if all of the inputs are open. Once all contacts signal no fill level alarm, the
controller evaluates this as no alarm.
Note
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.

Dependent Parameter
Fill level reached when
Options:
Contact open
Contact closed
This parameter defines how the input reacts if the fill level is evaluated as reached or not reached.
You can also define whether the fill level sensor is a normally closed or normally open contact.
•
Contact open
: The fill level is considered reached if the contact is open.
•
Contact closed
: The fill level is considered reached if the contact is closed.

Dependent Parameter
Send status value
Options:
After a change
On change and cyclically
•
After a change
: Sends the value only after a change.
•
On change and cyclically
: Sends the value after a change, and cyclically. Enables the depen-
dent parameter
Send input status cyclically
.
