Required Transmitter Configuration
4.7Configuring the discrete input
Note: Configure the transmitter channels for the required input/output types before configuring the discrete input. See Section 4.3.
CAUTION
Changing the channel configuration without verifying I/O configuration can produce process error.
When the configuration of a channel is changed, the channel’s behavior will be controlled by the configuration that is stored for the new channel type, which may or may not be appropriate for the process. To avoid causing process error:
•Configure the channels before configuring the discrete output (see Section 4.3).
•When changing the discrete output configuration, be sure that all control loops affected by this output are under manual control.
•Before returning the loop to automatic control, ensure that the discrete output is correctly configured for your process.
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 following actions may be assigned to the discrete input:
•Begin fill
•End fill
•Pause fill
•Resume fill
•Reset fill total
•Reset mass total
•Reset volume total
•Reset all totals
Note: If the filling and dosing application is active, the Reset All Totals function includes resetting the fill total.
To configure the discrete input, see the menu flowchart in Figure
4.8Establishing a meter verification baseline
Note: This procedure applies only if your transmitter is connected to an enhanced core processor and you have ordered the meter verification option. In addition, ProLink II v2.5 or later is required.
Meter verification is a method of establishing that the flowmeter is performing within factory specifications. See Chapter 10 for more information about meter verification.
Micro Motion recommends performing meter verification several times over a range of process conditions after the transmitter’s required configuration procedures have been completed. This will establish a baseline for how widely the verification measurement varies under normal circumstances. The range of process conditions should include expected temperature, pressure, density, and flow rate variations.
