Fault indication with the Discrete Output
To indicate faults via the 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.
6.5 Configure the Discrete Input
The Discrete Input is used to initiate one or more transmitter actions from a remote input
device. Your transmitter may have zero or one Discrete Input, depending on the
configuration of Channel C.
The Discrete Input parameters include:
• Discrete Input Action
• Discrete Input Polarity
Important
Whenever you change a Discrete Input parameter, verify all other Discrete Input parameters before
returning the flowmeter to service. In some situations, the transmitter automatically loads a set of
stored values, and these values may not be appropriate for your application.
6.5.1 Configure Discrete Input Action

Overview
Discrete Input Action controls the action or actions that the transmitter will perform when
the Discrete Input transitions from OFF to ON.
Important
Before assigning actions to an enhanced event or Discrete Input, check the status of the event or the
remote input device. If it is ON, all assigned actions will be performed when the new configuration is
implemented. If this is not acceptable, wait until an appropriate time to assign actions to the event
or Discrete Input.
Procedure
1. Select an action.
2. Select the Discrete Input that will perform the selected action.
3. Repeat until you have assigned all the actions to be performed by the Discrete Input.
