Page 16 Quick start Wait approximately 10 seconds for the power-up sequence to complete. Immediately after power-up, the transmitter runs through diagnostic routines and checks for error conditions. During the power-up sequence, Alarm A is active.

This alarm should clear automatically when the power-up sequence is complete. Check the status LED on the transmitter.

Page Make A Startup Connection To The Transmitter Quick start Make a startup connection to the transmitter For all configuration tools except the display, you must have an active connection to the transmitter to configure the transmitter. Follow this procedure to make your first connection to the transmitter. Identify the connection type to use, and follow the instructions for that connection type in the appropriate appendix. In the sample tag, this value is shown as 4.

See Section Verify the zero Verifying the zero helps you determine if the stored zero value is appropriate to your installation, or if a field zero can improve measurement accuracy. The zero verification procedure analyzes the Live Zero value under conditions of zero flow, and compares it to the Zero Stability range for the sensor. Confirm that the sensor is completely blocked in, that flow has stopped, and that the sensor is completely full of process fluid. Verify that the process fluid is not flashing or condensing, and that it does not contain particles that can settle out.

It does not prevent normal operational use. You can always disable write-protection, perform any required configuration changes, then re-enable write-protection. Page 32 Configure process measurement If the measurement unit you want to use is not available, you can define a special measurement unit. Options for Mass Flow Measurement Unit The transmitter provides a standard set of measurement units for Mass Flow Measurement Unit, plus one user-defined special measurement unit.

Page Configure Flow Damping Configure process measurement a. Set Mass Total Label to oz. The value you enter is automatically rounded down to the nearest valid value. The default value for Mass Flow Cutoff is 0. The recommended setting is 0.

Page Configure Volume Flow Measurement For Liquid Applications Configure process measurement The frequency output will report the actual flow rate, and the actual flow rate will be used in all internal processing.

Set Volume Total Label to pints. Page 46 Configure process measurement Note Although you cannot define a special measurement unit using the display, you can use the display to select an existing special measurement unit, and to view process data using the special measurement unit.

Base Gas Standard Volume Unit is the existing gas standard volume unit that the special unit will be based on. Page 52 Configure process measurement Effect of Flow Direction on frequency outputs Flow Direction affects how the transmitter reports flow values via the frequency outputs.

The frequency outputs are affected by Flow Direction only if Frequency Output Process Variable is set to a flow variable.

Table Effect of the Flow Direction parameter and actual flow direction on frequency outputs The range is 0. The default value for Slug Duration is 0. Page 57 Configure process measurement Overview Damping is used to smooth out small, rapid fluctuations in process measurement. Damping Value specifies the time period in seconds over which the transmitter will spread changes in the reported process variable.

Density Damping controls the rate of change in the density process variable. Added Damping controls the rate of change reported via the mA output. Page Configure Pressure Compensation Configure process measurement Overview Damping is used to smooth out small, rapid fluctuations in process measurement. Page 61 Configure process measurement Prerequisites You will need the flow factor, density factor, and calibration pressure values for your sensor.

If the data is unavailable, use 20 PSI. Choose an unused polling slot. Page 63 Configure process measurement The flow factor is the percent change in the flow rate per PSI. When entering the value, reverse the sign. Example: If the flow factor is 0.

Enter Density Factor for your sensor. Page Configure Pressure Compensation Using The Field Communicator Configure process measurement If you want to use digital communications, click Apply, then perform the necessary host programming and communications setup to write temperature data to the transmitter at appropriate intervals.

Postrequisites If you are using an external pressure value, verify the setup by checking the External Pressure value displayed in the Inputs area of the main window. Set Pressure Unit to the desired unit.

Set Compensation Pressure to the desired value. Polling for pressure a. You can set Display Precision independently for each variable. Setting Display Precision does not affect the actual value of the process variable.

Procedure Select a process variable. The default setting is Enabled. You cannot reset inventories from the display. You must reset totalizers individually. Page Configure Security For The Display Menus Configure device options and preferences Option Description Enabled default Operators can use a single display command to acknowledge all alarms at once.

Disabled Operators cannot acknowledge all alarms at once, they must be ac- knowledged individually. Page Configure Response Time Parameters Configure device options and preferences To require a password for access to the maintenance section of the off-line menu and the Smart Meter Verification menu, enable or disable Off-Line Password. Option Description Enabled Operator is prompted for the off-line password at entry to the Smart Meter Verification menu if applicable or entry to the maintenance section of the off-line menu.

Page Configure Update Rate Configure device options and preferences 5. Use basic events instead. Page Configure Alarm Handling Configure device options and preferences Overview Calculation Speed is used to apply a different algorithm to the calculation of process variables from the raw process data. Page Configure Status Alarm Severity Configure device options and preferences Overview Fault Timeout controls the delay before fault actions are performed.

For all other alarms, fault actions are performed as soon as the alarm is detected. Page 81 Configure device options and preferences Micro Motion recommends using the default settings for Status Alarm Severity unless you have a specific requirement to change them. Procedure Select a status alarm.

For the selected status alarm, set Status Alarm Severity as desired. Option Description Fault Informational A Sensor Simulation Active Applies only to flowmeters with the enhanced core processor. Can be set to either Informational or Ignore, but cannot be set to Fault. Page Configure Message Configure device options and preferences Procedure Enter a description for the transmitter. You can use up to 16 characters for the description. Page Configure The Ma Output Integrate the meter with the control system Postrequisites For each channel that you configured, perform or verify the corresponding input or output configuration.

Page 95 Integrate the meter with the control system Note Added Damping is not applied if the mA output is fixed for example, during loop testing or if the mA output is reporting a fault. Added Damping is applied while sensor simulation is active. Procedure Set Added Damping to the desired value. The exact time period is calculated by the transmitter according to internal algorithms which are not configurable. Page 99 Integrate the meter with the control system Overview Frequency Output Scaling Method defines the relationship between output pulse and flow units.

Set Frequency Output Scaling Method as required by your frequency receiving device. The default value is milliseconds. The default value is Hz. The range is 10 to Hz. Page Configure Discrete Output Source Integrate the meter with the control system Important Whenever you change a discrete output parameter, verify all other discrete output 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. Set Flow Switch Variable to the flow variable that you want to use to control the flow switch. Set Flow Switch Setpoint to the value at which the flow switch will be triggered after Hysteresis is applied.

Page Integrate the meter with the control system Overview Discrete Output Fault Action controls the behavior of the discrete output if the transmitter encounters an internal fault condition. Note For some faults only: If Last Measured Value Timeout is set to a non-zero value, the transmitter will not implement the fault action until the timeout has elapsed. The setting of Discrete Output Fault Action is ignored.

Configure events An event occurs when the real-time value of a user-specified process variable moves past a user-defined setpoint. Optional Configure a discrete output to switch states in response to the event status. Optional Specify the action or actions that the transmitter will perform when the event occurs. Page Configure Digital Communications Integrate the meter with the control system Configure digital communications The digital communications parameters control how the transmitter will communicate using digital communications.

Options Description Enabled The primary mA output reports process data as configured. Disabled The primary mA output is fixed at 4 mA and does not report process data. Page Integrate the meter with the control system Restriction The TV is automatically set to match the PV and cannot be configured independently. Code Byte order 1—2 3—4 3—4 1—2 2—1 4—3 4—3 2—1 Table Page Integrate the meter with the control system Overview Digital Communications Fault Action specifies the values that will be reported via digital communications if the transmitter encounters an internal fault condition.

The default setting is None. If you do not, the output will not report actual process data, and this may result in measurement errors or unintended consequences for your process.

Procedure Figure Configuration and Use Manual From this list, you can acknowlege individual alerts or choose to acknowledge all alerts at once. Page Start And Stop Totalizers And Inventories Transmitter operation Overview Totalizers keep track of the total amount of mass or volume measured by the transmitter since the last totalizer reset.

Inventories keep track of the total amount of mass or volume measured by the transmitter since the last inventory reset. You can use the inventories to keep a running total of mass or volume across multiple totalizer resets.

Page Transmitter operation 1. Important Because all totalizers are started or stopped together, it does not matter which total you use. Page Reset Inventories Transmitter operation 3. Select again to confirm. Scroll to EXIT. Scroll until the volume totalizer value appears. Page Transmitter operation Overview When you reset an inventory, the transmitter sets its value to 0. It does not matter whether the inventory is started or stopped.

If the inventory is started, it continues to track process measurement. When you reset a single inventory, the values of other inventories are not reset. Totalizer values are not reset. Table for the minimum version of the transmitter, enhanced core processor, and communication tool needed to support Smart Meter Verification.

Page Run Smart Meter Verification Measurement support Smart Meter Verification has an output mode called Continuous Measurement that allows the transmitter to keep measuring while the test is in progress. If you choose to run the test in Last Measured Value or Fault modes instead, the transmitter outputs will be held constant for the two minute duration of the test.
