Dependent Parameter
Dew point status input
This parameter is not visible if the
Device function
parameter has been parameterized with the
Ac-
tuator device
option.
This parameter is not visible if the
Basic-stage cooling
parameter is deactivated.
Options:
Deactivated
Via physical device input
Via group object
This parameter is used to inform the integrated controller whether it is to include the dew point
alarm (Alarm/No alarm) in the control.
•
Deactivated
: If
Deactivated
has been selected, the dew point alarm is not taken into account by
the controller.
•
Via physical device input
: If this option is selected, the controller checks which of the physical
device inputs has been parameterized for a dew point sensor. The status of the dew point sen-
sor connected to this input is included in the control.
The message: Configure in 'Inputs' parameter window appears.
Note
Only device inputs that have been parameterized as a dew point sensor are detected as such.
If no input has been parameterized as a dew point sensor, the function is considered deactivated.
If several inputs have been parameterized as a dew point sensor, there is a logical OR link be-
tween these inputs. As soon as one of the contacts signals the status "Dew point reached", the
controller evaluates the status as "Dew point alarm". Conversely, if none of the inputs signals the
status "Dew point reached", the controller evaluates the status as "No dew point alarm".
•
Via group object
: The dew point alarm is received via a group object. The dependent
Dew point
alarm
group object appears. In addition, the dependent
Dew point reached when
parameter is
enabled.
