Transmitter Configuration and Use: Series 1000 and 2000 Transmitters 67

6.7.1 Flow switch
Flow switch refers to the flow rate moving past a user-configured setpoint, in either direction. For
example, if the setpoint is 100 lb/min, a flow switch occurs if the flow rate changes from 101 lb/min
to 99 lb/min, or from 99 lb/min to 101 lb/min.
The flow switch has a 5% hysteresis. For example, if the setpoint is 100 lb/min, the flow switch will
be triggered when the flow rate falls below 100 lb/min, but not turned off until a 5% (5 lb/min) change
occurs (i.e., the flow rate rises to 105 lb/min).
If a discrete output is assigned to flow switch, the flow switch setpoint must be configured.
Note: If your transmitter is configured with two discrete outputs, it is possible to configure both DO1
and DO2 for flow switch, but it is not useful because you cannot configure independent setpoints.
6.8 Configuring the discrete input
The discrete input is used to initiate a transmitter action from a remote input device.
If your transmitter has been configured for a discrete input, the actions listed in
Table 6-16 may be assigned to the discrete input.
Note: Configure the transmitter for the required input/output types before
configuring the discrete input. See Section 6.3.
To configure the discrete input, see the menu flowcharts in Figure 6-14.
