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.

Overview
Discrete Input Action controls the action or actions that the transmitter will perform when the
discrete input transitions from OFF to ON.
CAUTION!
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.
