ABB i-bus® KNX PARAMETERS
7.4.140 Temperature input monitoring
This parameter is used to define whether the reception of a temperature value is monitored.
Note
For the monitoring of a physical device input to function, a temperature sensor must be connected
and the corresponding input must be set for the connection of a temperature sensor. The following
settings must be made:
• Parameter
Input \ Option Temperature sensor
• Parameter Actual temperature receipt \ all options except Via group object
Option
Deactivated Monitoring is deactivated.
On physical device input x
The reception of a temperature value on the physical device input x (x = a, b, c) is monitored.
The following actions will be performed if no valid temperature is measured at the input for longer
than one minute:
•
Group object Fault Actual temperature (master) is set to "Error"
• Value in the parameter
Control value on input fault
becomes valid
The following dependent parameters are shown:
•
Control value on input fault
The following dependent group objects are displayed:
•
Fault Actual temperature (master)
On group object The following group objects are monitored:
•
External temperature 1
• External temperature 2
The set time interval applies to both group objects. If a value is received on one of the group objects,
only the time interval of the affected group object restarts.
If a value is not received on one of the two group objects, the following actions are carried out:
•
Group object Fault Actual temperature (master) is set to "Error"
• Value in the parameter
Control value after exceeding monitoring time
becomes valid
The following dependent parameters are shown:
•
Time interval for cyclical monitoring
• Control value after exceeding monitoring time
The following dependent group objects are displayed:
•
Fault Actual temperature (master)
