Emerson Micro Motion 1600 - Options for Discrete Output Fault Action; Fault indication with a Discrete Output

Discrete Output Fault Action controls the behavior of a Discrete Output if the transmitter detects a fault
condition.
Important
• The fault action is implemented only if Alert Severity is set to Failure. If Alert Severity is set to any other
option, the fault action is not implemented.
• 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.
NOTICE
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

Upscale • Fault: Discrete Output is ON (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 by
its assignment
Downscale • Fault: Discrete Output is OFF (0 V)
• No fault: Discrete Output is controlled by
its assignment
• Fault: Discrete Output is ON (site-specific
voltage)
• No fault: Discrete Output is controlled by
its assignment
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.
