Quick start

2 Quick start

Topics covered in this chapter:

•Power up the transmitter

•Check meter status

•Make a startup connection to the transmitter

•Zero the meter

2.1Power up the transmitter

The transmitter must be powered up for all configuration and commissioning tasks, or for process measurement.

1.Ensure that all transmitter and sensor covers and seals are closed.

WARNING!

To prevent ignition of flammable or combustible atmospheres, ensure that all covers and seals are tightly closed. For hazardous area installations, applying power while housing covers are removed or loose can cause an explosion.

2.Turn on the electrical power at the power supply.

The transmitter will automatically perform diagnostic routines. During this period, Alert 009 is active. The diagnostic routines should complete in approximately

30 seconds.

Postrequisites

Although the sensor is ready to receive process fluid shortly after power-up, the electronics can take up to 10 minutes to reach thermal equilibrium. Therefore, if this is the initial startup, or if power has been off long enough to allow components to reach ambient temperature, allow the electronics to warm up for approximately 10 minutes before relying on process measurements. During this warm-up period, you may observe minor measurement instability or inaccuracy.

2.2Check meter status

Check the meter for any error conditions that require user action or that affect measurement accuracy.

1.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, Alert A009 is active. This alert should clear automatically when the power-up sequence is complete.

Configuration and Use Manual

Quick start

2.Check the status LED on the transmitter.

Table 2-1: Transmitter status reported by status LED

LED state	Description	Recommendation
Green	No alerts are active.	Continue with configuration or process meas-
		urement.
Yellow	One or more low-severity alerts are active.	A low-severity alert condition does not affect
		measurement accuracy or output behavior.
		You can continue with configuration or proc-
		ess measurement. If you choose, you can iden-
		tify and resolve the alert condition.

		calibration process. The alert will clear when
		the calibration is complete. Check the calibra-
		tion results before continuing.
Red	One or more high-severity alerts are active.	A high-severity alert condition affects meas-
		urement accuracy and output behavior. Re-
		solve the alert condition before continuing.
•	View and acknowledge status alerts (Section 8.3)
•	Status alerts, causes, and recommendations (Section 10.6)

2.3Make 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.

Identify the connection type to use, and follow the instructions for that connection type in the appropriate appendix. Use the default communications parameters shown in the appendix.

Communications tool	Connection type to use	Instructions
ProLink III	Modbus/RS-485	Appendix C
	HART/Bell 202
Field Communicator	HART/Bell 202	Appendix D

Postrequisites

(Optional) Change the communications parameters to site-specific values.

•To change the communications parameters using ProLink III, choose Device Tools >

Configuration > Communications.

8	Micro Motion® Compact Density Meters (CDM)

Quick start

•To change the communications parameters using the Field Communicator, choose

Configure > Manual Setup > HART > Communications.

Important

If you are changing communications parameters for the connection type that you are using, you will lose the connection when you write the parameters to the transmitter. Reconnect using the new parameters.

2.4Zero the meter

Zeroing the meter establishes a baseline for the velocity indicator by analyzing the sensor's output when there is no flow through the sensor tubes.

Note

Do not zero the meter if a high-severity alert is active. Correct the problem, then zero the meter. You may zero the meter if a low-severity alert is active.

In most cases, the default value (0) is adequate for flow indication. Do not zero the meter unless the velocity switch is being triggered incorrectly and you need to apply an offset to the velocity measurement.

•	Zero the meter using the display	(Section 2.4.1)
•	Zero the meter using ProLink III	(Section 2.4.2)
•	Zero the meter using the Field Communicator (Section 2.4.3)

2.4.1Zero the meter using the display

Restriction

You cannot change the Zero Time setting from the display. The current setting of Zero Time will be applied to the zero procedure. The default value is 20 seconds. If you need to change Zero Time, you must make a connection to the transmitter from a communications tool such as ProLink III.

Procedure

1.Prepare the meter:

a.Stop flow through the sensor by shutting the downstream valve, and then the upstream valve if available.

b.Verify that the sensor is blocked in, that flow has stopped, and that the sensor is completely full of process fluid.

c.Verify that the process fluid is not flashing or condensing, and that it does not contain particles that can settle out.

d.Remove or reduce sources of electromechanical noise if appropriate.

2.Start the zero process.

a.Navigate to the Zero menu: OFFLINE MAINT > OFFLINE CALIB > VEL ZERO.

Configuration and Use Manual

Quick start

b.Scroll to CAL VEL/ZERO and activate Select, then select CAL/YES?.

The status LED changes to flashing yellow while the zero is in progress.

3.Read the zero result on the display.

The display reports CAL PASS if the zero was successful, or CAL FAIL if it was not.

Postrequisites

Restore normal flow through the sensor by opening the valves.

Need help? If the zero fails:

•Ensure that there is no flow through the sensor, then retry.

•Remove or reduce sources of electromechanical noise, then retry.

•Set Zero Time to a lower value, then retry.

•If the zero continues to fail, contact Micro Motion.

•If you want to return the meter to operation using a previous zero value, choose OFFLINE MAINT > CAL > RESTORE VEL/ZERO.

2.4.2Zero the meter using ProLink III

1.Prepare the meter:

a.Stop flow through the sensor by shutting the downstream valve, and then the upstream valve if available.

b.Verify that the sensor is blocked in, that flow has stopped, and that the sensor is completely full of process fluid.

c.Verify that the process fluid is not flashing or condensing, and that it does not contain particles that can settle out.

d.Remove or reduce sources of electromechanical noise if appropriate.

4.1Verify the calibration factors

Display	Not available
ProLink III	Device Tools > Calibration Data
Field Communicator	Configure > Manual Setup > Calibration Factors

Overview

The calibration factors are used to adjust measurement for the unique traits of the sensor. Your device was calibrated at the factory. However, you should verify that the calibration factors that are configured in your device match the factory values.

Prerequisites

You will need the factory values for the calibration factors. These are provided in two locations:

•The calibration certificate shipped with your meter

•The label inside the transmitter's end-cap

Important

If the transmitter is not the original component, do not use the values from the transmitter label.

Procedure

1.View the calibration factors that are stored in the device.

2.Compare them to the factory values.

•If the values match, no action is required.

•If the values do not match, contact Micro Motion customer service.

4.1.1Calibration factors

The original calibration factors are obtained from factory calibration, and are unique to each device. They are used to adjust measurements for the specific physical properties of the device.

Contents of the calibration certificate

The calibration certificate contains several sets of factors:

Density calibration	Define the relationship between density and the response
coefficients	of your sensor
Temperature	Adjust density measurement for the effect of temperature
compensation coefficients	on sensor response
Pressure compensation	Adjust density measurement for the effect of pressure on
coefficients	sensor response
Flow compensation	Adjusts density measurement for the effect of flow on
coefficient	sensor response

The calibration certificate also provides the results of the Known Density Verification procedure that was performed at the factory.

For each calibration performed at the factory, the calibration certificate contains the data used to calculate the calibration coefficients.

CDM format and legacy format (A factors and K factors)

The calibration factors are provided on three calibration certificates:

•The first certificate provides the calibration factors in the CDM format, An, in SI units. These are obtained from factory calibration of your device.

•The second certificate provides the calibration factors in the legacy format, Kn, in SI units. These factors represent the current calibration factors converted to the format used by the 7835 and 7845 meters.

•The third certificate provides the calibration factors in the legacy format, Kn, in imperial units. These factors represent the current calibration factors converted to the format used by the 7835 and 7845 meters, and then converted to imperial units.

If you have existing programs that use the K factors, update your programs with the new K values in the appropriate units. In all other situations, use the A-format calibration factors.
