1.3 Considerations

General

Electrical vibration sensors, such as accelerometers, produce low-level signals proportional to their sensed vibration. With simple HART configuration, the transmitter converts the low-level sensor signal to a wireless-enabled signal.

Commissioning

The transmitter can be commissioned before or after installation. You can commission it on the bench before installation to ensure proper operation and to be familiar with its functions.

Make sure the instruments are installed in accordance with applicable field wiring practices.

The CSI 9420 device is powered whenever the power module is installed. To avoid depleting the power module, remove it when the device is not in use.

Installation

Introduction

When choosing an installation location and position, provide ample access to the transmitter. For best performance, the antenna should be vertical, with some space between objects in a parallel metal plane such as a pipe or metal framework. Pipes or framework may adversely affect the performance of the antenna.

Electrical

Smart Power Module

The power module contains two “C” size primary lithium/thionyl chloride batteries. Each power module contains approximately 2.5 grams of lithium, for a total of 5 grams in each pack. Under normal conditions, the power module materials are self-contained and are not reactive as long as the batteries and the power module pack integrity is maintained. Take care to prevent thermal, electrical, or mechanical damage and protect contacts to prevent premature discharge.

CAUTION!

Use caution when handling the power module. The power module may be damaged if dropped from heights in excess of 20 feet.

External DC line power

Certain versions of the CSI 9420 are available for connecting to an external 10-28 VDC power source. This is used in place of the power module.

WARNING!

The CSI 9420 may not carry the same hazardous area ratings when operated with external DC line power.

Sensor Make sensor connections through the cable entry at the side of the

connection head. Provide adequate clearance for cover removal.

MHM-97408, Rev 15 5

Introduction

Environmental

The transmitter operates within specifications for ambient temperatures between –40°F and 185°F (–40°C and 85°C).

Verify that the operating environment of the transmitter is consistent with the appropriate hazardous location certifications.

1.4 Return of materials

You may need to ship the CSI 9420 to an Emerson Product Service Center for return or maintenance. Before shipping, contact Emerson Product Support to obtain a Return Materials Authorization (RMA) number and receive additional instructions.

2 Configuration

Topics covered in this chapter:

• Configuration overview

• Configuration with a Field Communicator

• Configuration with AMS Device Manager

• Configuration with AMS Machinery Manager

2.1 Configuration overview

You can configure the CSI 9420 either prior to installation or after the device is installed at the measurement location. You do not need to physically install or connect to the transmitter to complete the configuration. The transmitter, however, reports an alert until the sensor is connected; this is the expected behavior.

Configuration

Note

The specific user interface for performing the configuration varies depending on the host used.

Procedure

1. Connect to a wired HART interface.

Skip this step if your CSI 9420 is purchased pre-configured from the factory.

2. Set the wireless network credentials (Network ID and Join Key) using wired

connection.

Perform this step for the device to join a wireless network. After the device has joined, you can complete the rest of the steps over a wireless link.

3. (Optional) Name the device (Tag and Device Description).

By default, the tag is VT xxxx, where xxxx is the unique radio ID on the wireless network. The device joins the network and operates correctly even if no changes are made, but it is usually preferable to name the device something meaningful for the specific application.

4. Specify the type of sensor installed (for example: 1 accelerometer, 1

accelerometer with temperature, or 2 accelerometers) and name the sensor.

The factory default configuration is one accelerometer named SENSOR 1. Complete this step for different configurations and name the sensor something meaningful for the specific application.

5. Enter the sensor sensitivity.

For improved accuracy, replace the nominal sensitivity value of 25 mV per g (2.55 mV per m/s2) (default) with the value corresponding to your specific sensor.

MHM-97408, Rev 15 7

Configuration

6. Specify the units (English, metric, or SI) that will be used for each parameter.

By default, units are set to English, unless the device is shipped to Japan.

7. Specify which measurements (velocity, temperature, etc.) correspond to the

process variables PV, SV, TV, and QV.

By default, PV is the Overall Velocity on sensor 1, SV is the PeakVue measurement on sensor 1, TV is the sensor 1 bias voltage, and QV is the supply voltage.

8. Specify alert levels.

Determine the thresholds at which measurement alerts will display and determine the behavior of device alerts.

9. Specify how the parameters will be published (optimized mode or generic

mode).

By default, the device is configured to use generic mode as it provides the most consistent overall performance.

10. Specify how often the parameters are published (update rate).

The default update rate is once every 60 minutes. A faster update rate is not recommended, unless the device is powered by an external power source, as it significantly reduces the power module life.

11. Optimize for power consumption.

Reduce the publish rate and set the LCD mode to Off to minimize power consumption. As an additional step, you can configure the PowerSave mode settings to extend the power module life.

12. Configure trending of parameters.

You can trend parameters in multiple locations such as in a plant historian, in AMS Machinery Manager, and in a DCS control system.

13. If the device configuration will not be managed by a HART DCS (such as DeltaV),

specify whether AMS Machinery Manager can make configuration changes.

By default, the device is set for a DCS to manage the configuration, and changes from AMS Machinery Manager are not permitted. You can, however, allow AMS Machinery Manager to make configuration changes by enabling MHM Access Control from AMS Device Manager or from a Field Communicator.

14. If the device is licensed for the Advanced Diagnostics application (spectral data

retrieval), configure storage of energy bands, spectra, and waveforms in the AMS Machinery Manager database.

With the Advanced Diagnostics application, you can collect data on-demand, automatically at periodic intervals, or on alert. Store on Alert is the recommended operating mode.

8 MHM-97408, Rev 15

2.1.1 Connect to a wired HART interface

Unless the CSI 9420 is purchased pre-configured from the factory, you must connect it to a wired HART interface. This is to define device credentials that allow the device to communicate on your wireless network. You can also define other device configurations such as sensor type and alert thresholds at this time.

Notes

• Use the wired HART interface only for configuration. Dynamic variables (such as measured

vibration parameters) are not updated when communicating on the wired interface.

• The CSI 9420 does not communicate simultaneously on both the wired and wireless HART

interfaces. You will lose wireless connectivity when you connect to the wired HART interface. Configuration changes are not reflected in a wireless host until connection has been reestablished. To avoid loss of synchronization, disconnect hosts relying on the wireless link when communicating with the device on the wired interface.

For example, if you are viewing a configuration screen in AMS Device Manager through a wireless link, and you leave this screen open while making changes with a Field Communicator, you will have to exit AMS Device Manager and then re-open it (or re-scan the device) after the wireless connection has been restored in order to see the changes.

Configuration

Procedure

1. Remove the transmitter back cover.

This exposes the terminal block and HART communication terminals.

Figure 2-1:

CSI 9420 terminal block with two-wire, polarity-independent connection

A. COMM terminals (power module version) B. HART COMM terminals (externally powered version)

2. Connect the power module or supply power using an external power source.

MHM-97408, Rev 15 9

Configuration

Field Communicator and power module connectionFigure 2-2:

3. Configure using a Field Communicator, AMS Device Manager, or any HART-enabled host.

Press Send to send configuration changes to the transmitter.

The CSI 9420 enters “HART Listen” mode for communication on the wired interface. HART Listen is displayed on the optional LCD, if it is installed.

If the device is unable to enter the HART Listen mode during its boot sequence or while performing its real-time vibration measurement, retry the initial wired HART handshaking sequence.

If repeated attempts to establish wired communication fail, you can force the device into a HART Listen mode by removing the transmitter front cover and pressing the CONFIG button once. Once the device enters HART Listen mode, it remains in this mode until you press the CONFIG button, the power cycles, or no activity is seen on the wired interface for three minutes. Pressing the CONFIG button a second time causes the device to exit HART Listen mode.

CAUTION!

The front electronics end cap (the cap covering the LCD) is certified for Class I, Division I in appropriate gas environments (check the nameplate on the device for details).

Exposing the electronics to a production environment can allow particulates, moisture, and other airborne chemicals to enter into the device, which could lead to contamination and potential product performance issues. In all cases, whenever opening the front end cap, be sure to seal it completely afterwards by tightening until the black O-ring is no longer visible. For an illustration on how to properly seal the end cap, see Figure 3-12.

10 MHM-97408, Rev 15

4. When configuration is complete over the wired HART interface, disconnect the transmitter from the communication wires to re-establish wireless communication.

This may take several minutes.

2.1.2 Set the wireless network configuration

This enables the transmitter to communicate with the Smart Wireless Gateway and with other systems. This is the wireless equivalent of connecting wires from a transmitter to a control system input.

Procedure

1. From the Smart Wireless Gateway, click Setup > Network > Settings to obtain the Network ID and Join Key.

2. Using a Field Communicator or AMS Device Manager with a wired modem, enter the Network ID and Join Key so that they match the Network ID and Join Key from the Smart Wireless Gateway.

Note

If the Network ID and Join Key are not identical to the gateway settings, the CSI 9420 will not communicate with the network.

2.1.6 Alert levels

The CSI 9420 sets HART status bits to indicate when measured values exceed the configured thresholds. Each measured value has three levels: Advisory, Maintenance, and Failed that can be set independently. These thresholds are pre-configured at the factory to reasonable generic values for single-stage, electric motor-driven equipment trains operating at 1200–3600 RPM.

The level at which these thresholds should be set depends on the type of equipment being monitored and on your specific process.

One rule of thumb for vibration is to examine the current level at which the equipment is operating. Assuming the equipment is in good working condition, set the Advisory level at 2x the current value (or at a minimum of 0.05 in/s RMS, whichever is greater), set the Maintenance level at 4x the current value, and set the Failed level at 8x the current value. For example, if the current value for Overall Velocity is 0.1 in/s, set the Advisory threshold at 0.2 in/s, the Maintenance threshold at 0.4 in/s and the Failed threshold at 0.8 in/s. While this type of vibration program is not recommended, it can provide a starting point when no other information is available.

A good rule of thumb for establishing the PeakVue alert levels is to use the rule of 10's. This applies for most rolling element bearing equipment with a turning speed between 900 and 4000 CPM. Using this approach, the Advisory alert would be set at 10 g's, the Maintenance alert at 20 g's, and the Failed alert at 40 g's. In general, PeakVue alert levels can then be interpreted as follows:

10 g's Indication of Abnormal Situation

20 g's Serious Abnormal Situation - Maintenance Plan Required

40 g's Critical Abnormal Situation - Implement Maintenance Plan

For more information on PeakVue, see Section 5.2.

The default alert thresholds for temperature correspond closely to a generic open dripproof (ODP) motor with class F insulation and a service factor of 1.15, operating at an ambient temperature of 40°C or below and at an altitude of 1000 meters or below . These values are also reasonable thresholds to use when there is no knowledge of the process, the type of machinery, or the operating environment. For more information, see Chapter 5.

Notes

• The supply voltage measurement is made under load conditions. The supply voltage may

read differently with the CSI 9420 versus other Emerson transmitters or multimeters.

• Prior to sensor connection, it is normal to see alerts related to bias failure. These alerts go

away when the sensor is installed correctly.

• When any measured process parameter (Velocity, PeakVue, or Temperature) exceeds the

configured Advisory, Maintenance, or Failed threshold, this causes an “Advisory” indication that you can view from AMS Device Manager (or in another graphical host). This indicator itself does not set a status bit.

2.1.7 Publishing mode

The CSI 9420 can publish in either of two modes: optimized or generic (default).

Optimized mode uses less power by combining a large amount of information into a single command. In this mode, only the four standard process variables (PV, SV, TV, and QV) are published at the specified update interval and cached in the Smart Wireless Gateway. When values are cached in the gateway, it is not necessary to wake the device for the host system to be able to read the variables. The other variables are still available, but any request to read one of them wakes the device and consumes power.

Generic mode publishes all the process variables the device can produce. This mode requires three publish messages, which requires approximately 5% more power.

If you are only trending measurements mapped to PV, SV, TV, and QV, use optimized mode. If you are trending additional variables, use generic mode.

2.1.8 Update rate

The default update rate is 60 minutes. This is the maximum (fastest) recommended update rate. You can change this at commissioning or at any time through AMS Device Manager, a Field Communicator, or the Smart Wireless gateway web server. You can set the update rate from 1 minute to 1 hour.

Note

If the device uses a power module, and is configured to publish at the fastest allowable update rate (once per minute), the power module is expected to last only about 2-3 months. For faster update rates, if your application allows it, use an external DC power option.

2.1.9 Minimize power consumption

The primary way to minimize power consumption is to reduce the publish rate.

Two other configuration settings that affect power consumption are:

• LCD (Liquid Crystal Display)

• PowerSave mode

LCD

Disable the LCD after installation is complete if it is not required during normal operation. It is neither necessary nor sufficient to physically remove the LCD; it must be disabled through configuration in order to save power. From AMS Device Manager, select the wireless network where the transmitter is connected, right-click the transmitter and select Configure > Manual Setup > General Settings tab > LCD Mode > Off.

Note

Disabling the LCD (not removing it, just disabling it) through configuration provides power savings of about 15–20%.

Configuration

Leave the LCD installed even if it is disabled to provide valuable diagnostic information. To view the LCD, remove the front cover and press the DIAG button. This wakes the device and displays current information. This can be beneficial for taking a quick reading and to aid in troubleshooting.

CAUTION!

The front electronics end cap (the cap covering the LCD) is certified for Class I, Division I in appropriate gas environments (check the nameplate on the device for details).

PowerSave mode

PowerSave mode is available in CSI 9420 devices that are Rev. 3 or later and it enables the device to make measurements less frequently, thereby conserving power. This is ideal when either power module life is more critical than the acquisition rate or when changes in vibration are only expected to occur over extended periods of time.

You can configure the settings for the PowerSave mode in AMS Machinery Manager (MHM Access Control must first be enabled) and in AMS Device Manager. The specific field is referred to as PowerSave Skip Multiplier. It is the number of times the transmitter skips data acquisitions between updates to the gateway.

At any point, the effective acquisition rate for the CSI 9420 is defined as:

Effective Acquisition Rate = (Update Rate) x (PowerSave Skip Multiplier)

MHM-97408, Rev 15 17

Configuration

Valid settings for the PowerSave Skip Multiplier range from 1X to 24X. In order to extend power module life, it should only be combined with a long update rate such as 60 minutes (54 minutes may be optimal for older versions of the CSI 9420). When this value is set to 1X, the CSI 9420 acquires a new reading at the update rate. A PowerSave Skip Multiplier of 2X combined with a 60-minute update rate results in a new acquisition every 120 minutes (every two hours). Similarly, a PowerSave Skip Multiplier of 24X with a 60-minute update rate results in a new acquisition every 1440 minutes (once per day).

2.1.10 Trend parameters

You can trend parameters in multiple locations such as in a plant historian or in AMS Machinery Manager. The method for configuring this functionality is contained in the associated software and the details of all the possibilities are beyond the scope of this manual. This manual only indicates some of the general capabilities and version requirements.

You can trend values in essentially any host that accepts Modbus or OPC inputs. Configure OPC tags and Modbus registers for wireless devices in the Smart Wireless Gateway web interface. Refer to the Smart Wireless Gateway User Manual for additional information. The settings in the gateway and the host must be consistent and entered in both locations (for example, Modbus register definitions).

DeltaV integrates native wireless I/O devices on the control network. Refer to the DeltaV documentation for more information on the required version. You can manage wireless devices as native HART devices, and trend variables accordingly. This type of installation also allows richer alerting and diagnostics because the full HART capabilities are available.

Ovation 3.3 or later also integrates the Smart Wireless Gateway with all the associated benefits of HART.

AMS Machinery Manager 5.4 or later supports HART functionality to read configuration and alert information, as well as the dynamic parameters from the CSI 9420. This allows AMS Machinery Manager to auto-discover all of the devices on the wireless mesh as well as the specific sensor configurations, units settings, and variable mappings for CSI 9420 devices.

Also, with AMS Machinery Manager and CSI 9420 devices (that are licensed for the Advanced Diagnostics application), you can trend Energy Band parameters. For more information, see Section 2.4.1.

DeltaV versions prior to 10.3 and Ovation versions prior to 3.3, though not integrated through HART, accept Modbus values from the wireless devices. DeltaV also accepts OPC values.

2.1.11 Remove the power module

The CSI 9420 device is powered whenever the power module is installed. To avoid depleting the power module, remove it when the device is not in use.

After you have configured the sensors and network, disconnect the communication leads, remove the power module (if the device is not already installed), and replace the transmitter cover. You should insert the power module only when you are ready to commission the device.

2.2 Configuration with a Field Communicator

You can configure the CSI 9420 using a Field Communicator. Follow the connection diagram in Figure 2-2.

A Rev 4 DD is recommended when using a Field Communicator to configure the CSI 9420. The DD for the CSI 9420 is located on the DVD that came with the transmitter. Refer to the Field Communicator User’s Manual for more details on DDs or go to http://

www2.emersonprocess.com/en-us/brands/Field-Communicator/Pages/SysSoftDDs.aspx

for instructions on adding a DD for CSI 9420.

Configuration

The CSI 9420 requires Field Communicator System Software version 3.2 or later.

Figure 2-4 through Figure 2-15 show the Field Communicator configuration menu trees for CSI 9420 using a Rev 4 DD. For ease of operation, you can access some common tasks in several locations of the menu structure.
