6.7.2 Interaction between Process Variable Fault Action and other
fault actions
The setting of
Process Variable Fault Action
affects the operation of the mA Outputs, Frequency Outputs,
and Discrete Outputs if the corresponding output fault actions are set to None.
Interaction between Process Variable Fault Action and mA Output Fault Action
If
mA Output Fault Action
is set to None, the mA Output signal depends on the setting of
Process Variable
Fault Action
.
If the device detects a fault condition:
1.
Process Variable Fault Action
is evaluated and applied.
2.
mA Output Fault Action
is evaluated.
•
If it is set to None, the output reports the value associated with the setting of
Process Variable
Fault Action
.
•
If it is set to any other option, the output performs the specified fault action.
If you want the mA Output to continue to report process data during fault conditions, you must set both
mA
Output Fault Action
and
Process Variable Fault Action
to None.
Interaction between Process Variable Fault Action and Frequency Output Fault Action
If
Frequency Output Fault Action
is set to None, the Frequency Output signal depends on the setting of
Process Variable Fault Action
.
If the device detects a fault condition:
1.
Process Variable Fault Action
is evaluated and applied.
2.
Frequency Output Fault Action
is evaluated.
•
If it is set to None, the output reports the value associated with the setting of
Process Variable
Fault Action
.
•
If it is set to any other option, the output performs the specified fault action.
If you want the Frequency Output to continue to report process data during fault conditions, you must set
both
Frequency Output Fault Action
and
Process Variable Fault Action
to None.
Interaction between Process Variable Fault Action and Discrete Output Fault Action
If
Discrete Output Fault Action
is set to None and
Discrete Output Source
is set to Flow Rate Switch, the
discrete output state during a fault depends on the setting of
Process Variable Fault Action
.
If the device detects a fault condition:
1.
Process Variable Fault Action
is evaluated and applied.
2.
Discrete Output Fault Action
is evaluated.
•
If it is set to None, and
Discrete Output Source
is set to Flow Rate Switch, the discrete output will
use the value determined by the current setting of
Process Variable Fault Action
to determine if a
flow rate switch has occurred.
