Dependent Parameter
Temperature input monitoring
This parameter is only visible if the
Device function
parameter has been parameterized with the
Controller
option.
Options:
Deactivated
On physical device input a
On physical device input b
On physical device input c
On physical device input d
On group object
The reception of a temperature value can be monitored using this parameter. Unlike the other
group objects to be monitored, here it is also possible to monitor a physical device input instead of
a group object. This is possible because the correct function of the temperature input is imperative
for the correct function of the device.
•
Deactivated
: The monitoring of the temperature input is deactivated.
•
On physical device input a/b/c/d
: The temperature sensor connected to the input selected is
monitored. If the input does not deliver a valid temperature value for more than a minute, the
fault value parameterized is used.
The
Control value on input fault
dependent parameter is displayed.
Note
For the monitoring to work, the related input must also be parameterized as a temperature sensor
and a temperature sensor must be connected to it. This setting is specified in the parameter win-
dow for the related input.
So that the temperature sensor connected also has an effect on the controller, the sensor must
also be assigned to the controller in the
Application parameters
parameter window in the
Temperature input
parameter by selecting the corresponding options (
Via physical device input
or
Via
physical device input and group object
).
Monitoring of one of the physical inputs is not allowed if
Temperature input - Via group object
has
been selected in the controller. This will result in the monitoring time being exceeded, because
the device inputs are monitored using very short times.
•
On group object
: The
External temperature 1
and
External temperature 2
(only if activated)
group objects are monitored. As soon as a new value is received in one of the two group ob-
jects, the monitoring time for the related group object starts again.
The dependent parameters
Time interval for cyclical monitoring
and
Control value after
exceeding monitoring time
as well as the
Fault: actual temperature
(master)
group object are
enabled.
Note
It is necessary that a value is received in both group objects within the monitoring time to prevent
the triggering of the cyclical monitoring.
