•
For some faults only: If
Fault Timeout
is set to a non-zero value, the transmitter will not implement the
fault action until the timeout has elapsed.
CAUTION
Do not use
Discrete Output Source
as a fault indicator. If you do, you may not be able to distinguish a fault
condition from a normal operating condition. If you want to use the Discrete Output as a fault indicator,
see
Fault indication with a Discrete Output
.
Procedure
Set
Discrete Output Fault Action
as desired.
Default: None
Options for Discrete Output Fault Action

•
Fault: Discrete Output is ON (24 VDC or
site-specific voltage)
•
No fault: Discrete Output is controlled
by its assignment
•
Fault: Discrete Output is OFF (0 V

No fault: Discrete Output is controlled

Downscale

None (default)
Discrete Output is controlled by its assignment
Fault indication with a Discrete Output
To indicate faults via a Discrete Output, set
Discrete Output Source
to Fault. Then, if a fault occurs, the
Discrete Output is always ON and the setting of
Discrete Output Fault Action
is ignored.
