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

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.

settings for these alerts are shown in Table 2-6.

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.

16 MHM-97408, Rev 15

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).

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.

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.

18 MHM-97408, Rev 15

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.

SpectraFigure 2-33:

The Fmax settings define the default frequency range of the thumbnail spectra for Velocity
and PeakVue. If you enable the Average Velocity option in AMS Machinery Manager, you
can configure the high-resolution Velocity Analytical spectrum to return 400 or 800 lines
of resolution, with averaging. If the Average Velocity option is not enabled in AMS
Machinery Manager, the spectrum is calculated at 1600 lines of resolution, with no
averaging.

When vibration data is acquired, a PeakVue waveform is sampled for 3.2 seconds. If you
set the PeakVue True Fmax to 1000 Hz, the first 1.6 seconds of the PeakVue waveform is
used for the analytical spectrum. If you set the Fmax to 500 Hz, the entire 3.2 second
PeakVue waveform is used to calculate the analytical spectrum. Regardless of what you
choose in Fmax, the overall PeakVue trend parameter is calculated over the entire 3.2
second waveform.

2.4 Configuration with AMS Machinery Manager

AMS Machinery Manager can change the data acquisition settings for CSI 9420 devices. If
the device is not commissioned in a HART DCS host (DeltaV or Ovation), you can allow
AMS Machinery Manager to configure settings to provide easier access. You need to
configure MHM Access Control in AMS Device Manager or in a Field Communicator to
allow AMS Machinery Manager to make configuration changes to the CSI 9420.

If the device is commissioned in a HART DCS host, manage the configuration completely
within the DCS. The DCS will generate an alert if you change the configuration externally.
For more details on how to change the configuration from AMS Machinery Manager, refer
to the Data Import topics in AMS Machinery Manager Help.

For device configurations managed by the DCS, you can still set independent alerts in AMS
Machinery Manager to allow you to get a notification without going to the DCS operator
(for example, you can set an alert at a lower threshold within AMS Machinery Manager).

If the primary HART host is AMS Device Manager, you can manage all alert configurations
and device update rates from AMS Machinery Manager. The independent alert levels are
still possible (for example: a different alert level in AMS Machinery Manager than in AMS
Device Manager). In this scenario, you have direct access to both settings. The HART alerts
are stored in the device and appear in AMS Device Manager and Alert Monitor. AMS
Machinery Manager alerts only appear when you are using the AMS Machinery Manager
software. This type of configuration is also acceptable if the DCS or PCS host is using
Modbus or OPC and not HART.

CAUTION!

If the CSI 9420 devices are commissioned and installed on a HART DCS or PCS that is managing
and archiving device configuration information, AMS Machinery Manager should NOT be used
to change the configuration. This will cause an alert in the DCS due to the mismatch. The
configuration may even be overwritten by the DCS, which can cause confusion.

2.4.1 Advanced Diagnostics application

The Advanced Diagnostics application is a licensed feature available in CSI 9420 devices.
Contact your Emerson Sales Representative or Product Support for additional details.

When this feature is enabled, you can view a compressed thumbnail spectrum from a
HART host, such as DeltaV or AMS Device Manager. The primary application however, is for
integration with AMS Machinery Manager.

This feature allows you to retrieve compressed thumbnail spectra, high-resolution spectra,
and analytical waveforms from the CSI 9420 and archive them in the AMS Machinery
Manager database. This energy band provides additional insight, over and above the
trended scalar values. This information provides a better indication of whether or not there
is a real problem and, if so, how severe the problem is. By using the energy band, you can
determine whether or not the vibration energy is periodic and at what frequency it is
occurring.

58 MHM-97408, Rev 15

Configuration

Other configurable parameters for the energy band include:

• Effective Fmax for the thumbnail spectrum — For the velocity thumbnail

spectrum, AMS Machinery Manager uses 100% as the default Fmax.

• True Fmax for PeakVue — This allows the monitoring of a slower machine with

PeakVue. Choosing 1000 Hz Fmax uses about 1.6 seconds of data to produce a 1000
Hz analytical spectrum. Choosing 500 Hz Fmax uses about 3.2 seconds of data to
produce a 500 Hz analytical spectrum. The 1000 Hz Fmax is better for 1800–3600
RPM machines. The 500 Hz Fmax is better for slower machines.

Note

True Fmax for PeakVue can only be configured in AMS Machinery Manager (MHM Access
Control must first be enabled).

• Averaging for the high-resolution velocity spectrum — Averaging the velocity

spectrum reduces the effect of transients in the data. If you use averaging, the
frequency resolution of the high-resolution spectrum is 1.25 Hz/bin (800 lines) or 3
Hz/bin (400 lines). If you do not use averaging, the frequency resolution is 0.625 Hz/
bin. The Fmax for all high-resolution spectra is 1000 Hz. 400-line averaging is
enabled by default.

Data acquisitions can be on-demand, alert-based, or time-based. You can configure data
acquisition settings in the AMS Machinery Manager Data Import program.

An on-demand spectrum (usually a thumbnail) provides a quick look at the vibration
energy in the frequency domain. If you need more frequency resolution, you can obtain a
high-resolution spectrum or a waveform. You can store data in AMS Machinery Manager
database if the point is mapped.

You can configure time-based data acquisitions once; it happens automatically thereafter.
You can define the type of data to collect (compressed spectrum, high-resolution
spectrum, or waveform) and how often to collect and store data in the AMS Machinery
Manager database. AMS Machinery Manager automatically stores all time-based data
retrieved for future viewing and analysis.

With Alert-based data acquisitions, overall vibration and PeakVue measurements are
processed to determine the alert state of the equipment being monitored. Then you can
select at what alert level to trigger retrieval of the spectrum or waveform associated with
that sensor. Alert-based data acquisition typically results in a longer life for your Smart
Power Module.

Notes

• It is not necessary to transmit both waveform and spectrum from the CSI 9420. The spectrum

is about half as much data to transmit as a waveform. If you need the waveform, the spectrum
does not have to be transmitted because the software calculates the spectrum from the
stored waveform.

• When using a power module, use care when configuring time-based retrieval of energy band.

Transmitting high-resolution spectrum or waveforms consumes more energy and reduces the
life of the power module.

MHM-97408, Rev 15 59

Configuration

When using a power module, the maximum recommended time-based acquisition rates
are:

• Thumbnail spectrum — Once per day

• High-resolution spectrum — Once every two weeks

• Waveform — Once per month

On-demand data collection is not expected to have a significant impact on power module
life. If you are using a power module, keep in mind that even on-demand acquisitions can
have an adverse effect on the power module life if you request data, especially high­resolution data, too frequently.

For more information on these data acquisitions, refer to the Data Import topics in AMS
Machinery Manager Help.

2.4.2 CSI 9420 Data Collection: Overview

Data collection on the CSI 9420 includes taking an acquisition and storing it in memory
where it is available to be transmitted. AMS Machinery Manager obtains data from a CSI
9420 through the Data Import Server communication to the gateway device. You can view
or change data collection settings through AMS Machinery Manager, in the Data Import
program. You can set up policies and fine-tune your data collection based on time or
alerts.

62 MHM-97408, Rev 15

Configuration

To make changes to a CSI 9420, AMS Device Manager settings must allow AMS Machinery
Manager to make changes.

Note

In some cases, if the gateway device is connected to a HART host such as DeltaV, any changes made
using the AMS Machinery Manager software will be rejected. In such cases, contact your DeltaV
administrator or an instrument technician who is authorized to make the required configuration
changes.

Alert-based data collection (Enable Store on Alert)

When you chose an alert-based data collection, overall vibration and PeakVue
measurements are processed to determine the alert state of the equipment being
monitored. Then you can select at what alert level to trigger retrieval of the spectrum or
waveform associated with that sensor. Alert-based data collection typically results in a
longer life for your Smart Power Module.

Time-based data collection (Disable Store on Alert)

When you choose time-based data collection, you can store waveforms, high-resolution
spectra, and thumbnail spectra are requested on a timer. The same information is
collected periodically without regard to the device's alert status. Time-based data
collection typically shortens the life of your Smart Power Module.

CSI 9420 Publishing Policy

The Data Import program provides an easy credit-based system to control how often data
is collected and transmitted from each of your CSI 9420 transmitters. You can collect on­demand acquisitions without impacting the CSI 9420 Publishing Policy.

On-demand acquisitions

When you collect on-demand acquisitions you do not impact the CSI 9420 Publishing
Policy. Time-based or Alert-based acquisition requests will continue according to the
acquisition parameters for that device. All acquisitions, however, impact the life of your
Smart Power Module.

2.4.3 CSI 9420 publishing policy

The CSI 9420 publishing policy is a credit-based system to control automated data
requests and publishing rates. It helps you easily limit data traffic and data collection on
your CSI 9420 transmitters. For CSI 9420 transmitters with a Smart Power Module, a
publishing policy also helps extend the life of the power module by limiting the data
collection and publishing. The publishing policy does not prevent on-demand readings.
You can collect an on-demand reading from the CSI 9420 at any time.

The publishing policy may help if you have many transmitters and have some of the
following concerns:

• You want to conserve the life of your Smart Power Module.

• You may have a control environment.

• You want to limit how often you request data.

MHM-97408, Rev 15 63

Configuration

• You want to limit how often you collect and store data.

Consider the following example in which a CSI 9420 is configured for a 60 minute update
rate and to request the PeakVue spectrum whenever the PeakVue value exceeds 10 g's. If
the measurement stays above 10 g's for an extended period of time, AMS Machinery
Manager, without a publishing policy, would request a new spectrum with every
measurement or once every hour. Each subsequent spectrum adds relatively little value in
terms of diagnostic capability, but continues to consume power, which needlessly
shortens the life of the power module. It also consumes unnecessary bandwidth, which
might jeopardize the system's ability to retrieve pertinent diagnostic data from other
devices. The default CSI 9420 publishing policy would restrict duplicate transmissions from
this particular transmitter for two weeks. If the PeakVue level were still above 10 g at that
time, then the publishing policy would permit the transmitter to send through an
additional spectrum. This pattern would continue every 2 weeks until the issue is resolved.

How a publishing policy works

The publishing policy is based on gateway credits, device credits, and a polling interval.
Credits are consumed by automated data collection based on the acquisition type. On­demand acquisitions do not consume credits. The credits are applied and used per polling
interval. If the polling interval is too short, a device may send data too often, clog the
network bandwidth, and run down the power module. Therefore, you should set the
polling interval to the longest time period that is practical.

Device credit consumption by acquisition typeTable 2-9:

Acquisition Credit

Spectrum (time-based or alert-based) 1

Waveform (time-based or alert-based) 2

Spectrum or Waveform (on-demand) 0

You can determine if a device has consumed all of its credits by viewing the CSI 9420
device status. In Data Import, expand the Device Hierarchy to a CSI 9420, right-click the
CSI 9420, and select Get Status. A status message at the bottom of the screen displays the
date and time when the device will be eligible to collect data automatically.

Data storage and retrieval order with alert-based data collection

Combining a publishing policy with alert-based automated data collection provides more
control over data collection, while ensuring you have the latest data when the conditions
worsen. If more than one transmitter sends alerts at the same time, the requests are
handled on a first come, first served basis. Newer transmitters (units with software rev 6.0
or higher) will retain the alert data in a protected memory buffer until it is retrieved by AMS
Machinery Manager. For older transmitters (units with software below rev 6.0), AMS
Machinery Manager will retrieve whatever data is contained in the transmitter's memory at
the time the request is processed. Also, with a newer transmitter, if the condition gets
worse while the data is waiting to be retrieved, the transmitter will update its stored data
with the latest measurement due to the higher alert level.

64 MHM-97408, Rev 15

Configuration

How to apply a publishing policy

You can apply a publishing policy globally to a Data Import Server or individually to each
gateway device.

• Apply a publishing policy to a Data Import Server to affect each gateway monitored

by that server.

• Apply a publishing policy to one gateway device to affect only the CSI 9420

transmitters connected to that gateway device.

2.4.4 Maximum network size and publishing policy settings

The maximum network size for use with Emerson's Smart Wireless Gateway is defined in

Table 2-10.

Maximum network sizeTable 2-10:

Number of wireless devices Update rate (in seconds)

12 1

25 2

50 4

100 8+

You can have up to 100 CSI 9420 devices on a single gateway, as the HART variables (i.e.
scalar values) never have an update rate faster than 60 seconds. The update rate is
typically once every 60 minutes.

The maximum network size decreases as you add different types of wireless devices to
your network and when you collect high-resolution data. For example, if 5 temperature
transmitters are broadcasting at a 1 second update rate, you will be able to add fewer CSI
9420 devices on this gateway than if the network contained only CSI 9420 devices. When
you collect high-resolution data from a CSI 9420, such as vibration spectra and waveforms,
the network can accommodate fewer wireless devices.

AMS Machinery Manager controls spectrum and waveform collection. The software
features a publishing policy that limits the amount of data broadcast from a single device
or over a single gateway. Figure 2-40 shows the menu to configure the publishing policy in
the (Modbus) Data Import program. Table 2-11 shows the recommended (default)
publishing policy settings. The default settings allow only 4 devices to send a full set of
diagnostic data in a 24-hour period and no device will send data more often than every two
weeks. This ensures that diagnostic data does not compete with process data, and that no
single device dominates the available bandwidth.

9420 Publishing Policy menu with default values shown in Table 2-11.

If a gateway is dedicated to vibration monitoring and will not be routing any process data,
then you can customize the publishing policy to allow more diagnostic data to be
collected. Follow these steps:

1. Use the settings in Table 2-12 and Table 2-13 to achieve the maximum network size

as indicated.

2. Set up efficient data collection as follows:

• Use/create a well-formed network which conforms to best practices as described

in the WirelessHART System Engineering Guide.

• Collect an averaged spectrum for overall vibration (recommended). Do not

collect the waveform used to calculate the overall vibration value in the device
itself. Starting in AMS Machinery Manager v5.61, the spectrum can be 400 lines
instead of 800 lines, which further increases the availability of bandwidth. If you
require the waveform from overall vibration, you can collect it on demand.

• For PeakVue, collect the waveform; the spectrum is always collected with the

waveform. You need the waveform in order to use Auto-correlation to look for
periodicity in the waveform. Auto-correlation helps you distinguish between
impacting that is the result of under-lubrication or pump cavitation versus actual
bearing damage.

MHM-97408, Rev 15 67

Configuration

2.4.5 Waveform or spectrum time

The amount of time required to get a waveform or spectrum varies significantly depending
on the network size, network topology, and other installed applications competing for
wireless bandwidth. Demand-based acquisitions use a special high-bandwidth mechanism
that can transfer a 4096-point waveform in less than 5 minutes in optimum conditions,
although it can take as much as 1 hour in fully loaded networks. Time-based acquisitions
run at a lower bandwidth and typically take at least 30 minutes to acquire the same
waveform.

Refer to the Data Import topics in AMS Machinery Manager Help for more details.

Energy Band trends

The transmitted thumbnail spectra, regardless of effective Fmax, also include Energy Band
parameters which cover the entire frequency range. The Energy Bands for a 1000 Hz
spectrum are:

• 0 Hz – 65 Hz

• 65 Hz – 300 Hz

• 300 Hz – 1000 Hz

The Energy Band parameters can only be trended in AMS Machinery Manager, and they are
trended in the same way as the other scalar parameters. The device does not publish these
values—requesting these wakes the device just like any other special data request.

Trend values are a good way to view on-demand data from your CSI 9420 powered by a
Smart Power Module because these trend values come from the Smart Wireless Gateway's
cache. Viewing on-demand trends does not cause the CSI 9420 to collect or transmit data
as on-demand spectra and waveforms do.

The maximum (fastest) recommended storage rate for the Energy Band parameters is
every 8 hours.

Refer to the Data Import topics in AMS Machinery Manager Help for more information.

Topics covered in this chapter:

• Power the CSI 9420

• Sensors

• Liquid Crystal Display (LCD)

• Ground the transmitter

3.1 Power the CSI 9420

Prerequisites

Install the Smart Wireless Gateway and ensure it is functioning properly before installing
the CSI 9420 and all other wireless devices.

Procedure

Setup

1. Remove the transmitter back cover to access the power connections.

2. Provide power to the transmitter:

• For the battery-powered version, plug in the power module.

• For the externally powered version, connect a 10–28 VDC (24 V nominal) power

supply to the bottom two screw terminals on the right.

Note

When selecting the power supply, note that each CSI 9420 has a peak current draw of 40 mA
when awake and powering sensors.

3. Pull the wiring through the threaded conduit entry.

Ensure that the grommet fits the wire properly and does not leak.

Note

The wire must snugly fit in the grommet feed-through in the cable gland to prevent ingress of
water and other contaminants. If using one of the grommets for the standard low-power
accelerometers, use a cable with a diameter between 0.125 to 0.250 in. (3.175 - 6.35 mm) to
maintain a good seal. If a good seal is not possible with the wire selected, use an alternative
grommet that provides a good seal.

Additional recommendations for power wiring:

• Install a Ferrite EMI filter inline with the wire to block electrical noise (included with

package). Refer to Section 6.1.3 for more information.

• Use 22 gauge or larger wiring (keep current requirements in mind when connecting

multiple transmitters inline).

MHM-97408, Rev 15 69

Setup

Tip

Power up wireless devices in order of proximity to the Smart Wireless Gateway, beginning with the
closest device to the gateway. This results in a simpler and faster network installation.

3.2 Sensors

Each of the CSI 9420 signal inputs uses accelerometers to make vibration measurements.
The term "sensor" applies to both an accelerometer and an accelerometer with embedded
temperature. The CSI 9420 uses special low-power sensors to reduce power consumption
and increase power module life. The sensor is available with or without embedded
temperature.

3.2.1 Sensor operating limits

Sensor operational rangesTable 3-1:

Channel DC bias range DC input range AC input range

Accelerometer 1 2–3 VDC 0–5 VDC 0.5–4.5 V (+/-80 g's peak)

Accelerometer 2 2–3 VDC 0–5 VDC 0.5–4.5 V (+/-80 g's peak)

Temperature 1 N/A -40°C to 125°C N/A

The accelerometers require a DC bias. The CSI 9420 provides the necessary bias and
measures it to verify correct sensor operation. The nominal bias voltage is 2.5 V. If the bias
voltage is outside of the 2–3 V range, the device generates a failed alert for the associated
sensor. The DC input range represents the operational DC range of the signal input. The AC
input range represents the operational AC range of the signal input.

3.2.2 Sensor handling

Note

Each sensor requires a standard 1/4–28-inch mounting location.

CAUTION!

Do not drop, hammer, or impact the sensor housing before, during, or after installation.

CAUTION!

Do not exceed the specified torque when tightening a stud-mounted sensor. Over-tightening a
sensor will damage the sensing element and void the manufacturer’s warranty.

70 MHM-97408, Rev 15

Setup

CAUTION!

Although the integral cable has a built-in strain relief, do not use excessive force when pulling
the cable. Do not exert more than 5-lb of force directly on the sensor connection during
installation. If possible, secure the cable to the machine near the point of sensor installation.

CAUTION!

Do not exert more than 5-lb pull force directly on sensor/cable connection during wire pulls.

For sensors that have been mounted before pulling the cable through the conduit or
raceway to the CSI 9420, leave the cable bundled and secured to the machine. Permanent
signal degradation takes place when cables are damaged. Do not step on, kink, twist, or
pinch cables. Also take note of the placement of the cable bundle. Do not place bundles in
a manner that may cause strain at the sensor/cable connection.

WARNING!

If the sensor is installed in a high-voltage environment and a fault condition or installation
error occurs, the sensor leads and transmitter terminals could carry lethal voltages. Use
extreme caution when making contact with the leads and terminals.

For high-voltage environments, attach the sensor leads first before connecting to a power
source.

Tip

Use crimp-on ferrules or lugs to improve long-term reliability of sensor wiring.

3.2.3 Sensor mounting/attachment tools and supplies

Mounting tools

• Drill

• Spot face or end mill tool

The spot face tool attaches to a standard electric drill and provides a machined surface that
is at least 1.1 times greater than the diameter of the sensor. The spot face tool also drills a
pilot hole that can then be tapped for a stud mounted sensor.

You can purchase the spot face tool from Emerson (MHM P/N 88101), or you can
substitute a spot face tool with similar characteristics as required. Contact your local sales
representative for assistance.

Description: 3/8" drive inch-lb torque wrench. You can substitute with any torque
wrench with a range of 40 to 70 inch-lb and less than 5 inch-lb increments.

• 1/4-28" taps and tap handle

• 9/16" open-end wrench

• 1/8" hex Allen key

• Wire brush

• Plant-approved cleaner/degreaser

• Plant-approved semi-permanent thread locker (e.g. Loctite)

For epoxy mount, you also need the following:

• 2-part epoxy (e.g. Loctite Depend [Emerson P/N A92106] or comparable)

• A212 Mounting Pads

A212 mounting padFigure 3-2:

• (Optional) Grinder – to create a sufficiently flat mounting surface

72 MHM-97408, Rev 15

3.2.4 Prepare the sensor mount

Stud mount (preferred)

Stud mount provides increased reliability, improved frequency response, and increased
signal sensitivity.

Prerequisites

The mounting location must provide a flat surface of at least 0.5 in. (12.7 mm) in diameter
and a case thickness exceeding 0.4 in. (10.2 mm). If this is not possible, use the epoxy
mount method instead

Procedure

1. Prepare the spot face or end mill tool by setting the drill bit depth to a minimum of

0.325 in. (8.255 mm).

2. Using a wire brush and plant-approved cleaner, clean and degrease the surface area.

3. Keeping the spot face and end mill tool perpendicular to the machine surface, drill
into the mounting location until the surface is smooth to the touch with no
noticeable irregularities. This may require the spot face tool to remove as much as

0.04 in. (1.016 mm) or more from the surface.

Setup

Note

If the spot face is not uniform on all sides, it indicates that the spot face tool is not
perpendicular to the mounting surface, and the resulting surface will not allow the sensor to
be mounted properly. See Section A.7 for illustrations of the correct milling process.

4. Using 1/4-28 in. tap set, tap a pilot hole to a minimum depth of 0.25 in. (6.35 mm).

See Section A.7 for an illustration of tapping a pilot hole.

Epoxy mount (alternative)

If it is not practical to drill into the machine casing, then the epoxy mount method is
acceptable.

Procedure

1. If the equipment surface has a radius of curvature that is less than 4 in. (100 mm),
grind a flat surface approximately 0.5 in. (12.7 mm) in diameter.

2. Using a wire brush and plant-approved cleaner, clean and degrease the surface area.

3. Using a 2-part epoxy (such as Emerson P/N A92106), spray the activator onto the
mounting surface. Place a light coat of epoxy on the surface of the mounting pad
and hold firmly against the machine spot face surface for 1 minute.

Note

If the adhesive does not set within 1 minute, it indicates that too much epoxy is applied or
that the mounting surface is not prepared properly. Repeat steps 2–3.

Setup

3.2.5 Attach the sensors

Figure 3-3 shows a typical accelerometer, mounting stud, and mounting pad used with the

CSI 9420. The mounting pad is only necessary when doing an epoxy mount.

Prerequisites

Whenever possible, mount sensors to the machine while pulling cables. If you have to
mount the sensor at another time, secure the bundled cable to the machine and protect it
from damage.

Procedure

1. Using a plant-approved cleaner/degreaser, remove any lubricating fluid used during
the tapping process and if necessary, clean the mounting stud threads.

2. Rub a small amount of semi-permanent thread locker onto the mounting location.

74 MHM-97408, Rev 15

Apply thread locker onto mounting locationFigure 3-4:

3. Using a 1/8 in. Allen key (English mounting stud) or a 4 mm Hex Allen key (metric
mounting stud), loosely screw the mounting stud into the mounting location.

Setup

The mounting location is the machine surface when using stud mount and the
mounting pad when using epoxy mount.

4. Using a torque wrench with 1/8 in. hex bit, torque to 7–8 ft-lb (9.5–10.8 N-m) to
tighten the mounting stud.

Tighten the mounting studFigure 3-5:

MHM-97408, Rev 15 75

Setup

For stud mount: If the mounting stud is still not seated against the spot face after
you apply the correct torque force, it indicates that the tap hole is not deep enough.
Remove the mounting and tap a deeper hole.

5. Apply a thin coat of semi-permanent thread locker to the threads on the sensor
housing.

6. Place the sensor onto the mounting stud and hold it to create the least amount of
cable strain and cable exposure. While holding the sensor, hand-tighten the 9/16 in.
captive nut and use a torque wrench with 9/16 in. open end to finish tightening to
2–5 ft-lb (2.7–6.8 N-m).

Hand-tighten the captive nutFigure 3-6:

If the mounting stud does not disengage from the sensor, use a flathead screwdriver
to hold the stud and turn the hex nut counter-clockwise with a wrench.

3.2.6 Secure the sensor cables

WARNING!

All wiring should be installed by a trained and qualified electrician. Wiring must conform to all
applicable local codes and regulations. Follow local codes and regulations regarding wire type,
wire size, color codes, insulation voltage ratings, and any other standards.

Using an appropriately sized cable clamp, secure the sensor cable to the machine
approximately 4–5 in. (100–125 mm) from the mounting location. Do not curl into a
bending radius of less than 2.8 in. (71 mm).

Securing a cable with temporary cable anchorFigure 3-7:

Setup

If the pulling of cables is not currently scheduled, secure the bundled sensor cables so that
no strain is placed on the integral sensor/cable connectors. Do not let the bundled cable
hang from the sensors. Do not place cables on plant floors, maintenance access areas,
and/or footholds that may cause damage to the cables.

Important

Moving one LCD around to multiple devices, on an “as need” basis, is NOT recommended.
This can cause reliability problems over time. The connector pins on the LCD are not designed
for repeated connect/disconnect.

3.3.2 Enable the LCD

When you enable the LCD, the CSI 9420 displays information about its network state and
its measurements. This is helpful for configuration, installation, and commissioning. The
LCD provides a visual indication on the status of the device and shows its current
measurements.

Transmitters ordered with the LCD are shipped with the display installed but with the LCD
disabled/turned off. You need to enable the LCD using a Field Communicator or using AMS
Device Manager.

Enable the LCD using a 375 or 475 Field Communicator

1. Use the lead set to connect the Field Communicator to the CSI 9420 terminal block.

2. Turn on the Field Communicator.

3. Select Configure > Manual Setup > General Settings > LCD Mode > Periodic Display.

Options available for LCD configuration include:

• Not installed – Use this setting if the LCD is not installed.

MHM-97408, Rev 15 83

Setup

• Periodic Display – Use this setting to show only relevant data. This setting does not

extend the wake cycle.

• Troubleshooting Display – Use this setting when troubleshooting the transmitter.

• Off – Use this setting to disable the LCD.

Enable the LCD using AMS Device Manager

1. Launch AMS Device Manager and locate the network where the CSI 9420 is
connected.

2. Right-click the CSI 9420 device and select Configure > Manual Setup.

3. Click the General Settings tab and from the LCD Mode drop-down menu, select Periodic
Display.

Options available for LCD configuration include:

• Not installed – Use this setting if the LCD is not installed.

• Periodic Display – Use this setting to show only relevant data. This setting does not

extend the wake cycle.

• Off – Use this setting to disable the LCD.

Note

When operating the CSI 9420 with the Smart Power Module, disable the LCD in the transmitter
configuration after installation to maximize power module life. While the LCD module itself
consumes very little power, having it activated will alter the operating cycle of the transmitter in
such a way that can impact the power module life by up to 15–20%.

3.3.3 Turn on the LCD

1. Remove the LCD cover.

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 may allow particulates, moisture,
and other airborne chemicals to enter into the device, which could lead to
contamination and potential product performance issues.

2. Press the DIAG button to turn the LCD on.

This displays the Tag name, Device ID, Network ID, Network Join Status, and Device
Status screens.

3. Attach the LCD cover.

84 MHM-97408, Rev 15

Use a strapping wrench to tighten the cover until it will no longer turn and the black
O-ring is no longer visible. Refer to Figure 3-12 for an illustration on how to properly
seal the end cap.

3.4 Ground the transmitter

The transmitter operates with the housing, either floating or grounded. However, the
extra noise in floating systems affects many types of readout devices. If the signal appears
noisy or erratic, grounding the transmitter at a single point may solve the problem.

You can reduce electrostatic current in the leads induced by electromagnetic interference
by shielding. Shielding carries the current to the ground and away from the leads and
electronics. If the transmitter end of the shield is adequately grounded to the transmitter
and the transmitter is properly grounded to the earth ground, very minimal current enters
the transmitter.

If the ends of the shield are left ungrounded, a voltage is created between the shield and
the transmitter housing, and between the shield and earth at the element end. The
transmitter may not be able to compensate for this voltage, causing it to lose
communication and/or generate an alarm. Instead of the shield carrying the current away
from the transmitter, the current flows through the sensor leads and into the transmitter
circuitry where it interferes with circuit operation.

Setup

Each accelerometer contains a drain wire that is connected to the sensor shield. This wire
should be connected to the internal grounding screw attached to the housing near the
terminal block.

Ground the transmitter in accordance with local, national, and international installation
codes. You can ground the transmitter through the process connection, the internal case
grounding terminal, or the external grounding terminal.

Field Communicator

You can verify the status of the CSI 9420 and configure it using a Field Communicator.
Table Table 4-2 shows the fast key sequences you can use to configure and connect the CSI
9420 to a network. See the Section 2.2 and Section 2.2.1 for more information on the Field
Communicator menu trees.

Note

HART Wireless transmitter communication requires a CSI 9420 Device Descriptor file (DD). The DD is
included on the DVD that came with the device. 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

Note

The CSI 9420 does not publish any data to the gateway while a Field Communicator or HART modem
is attached to it. After removing the leads from the Field Communicator/HART modem, the CSI 9420
senses that this connection has been removed and resumes publishing data to the gateway;
however, this process can take several minutes. Pressing the "CONFIG" button on the local operator
interface (when the CSI 9420 is not already engaged in performing another task) forces the CSI 9420
to switch operating modes.

Smart Wireless Gateway

From the Smart Wireless Gateway web server, navigate to the Explorer page. This page
shows if the device has joined the network and if it is communicating properly.

88 MHM-97408, Rev 15

Operation and maintenance

The Explorer page displays the transmitter tag name, PV, SV, TV, QV, time of last update,
and update rate (burst rate). A green status indicator means that the device is working
properly. A red indicator means there is a problem with either the device or its
communication path.

Note

It is normal for the CSI 9420 to have a red “X” on the screen until the sensor is installed.

Smart Wireless GatewayFigure 4-1:

Click on a tag name to display more information about the device.

If the CSI 9420 is configured with the Network ID and Join Key, and sufficient time for
network polling has passed, the transmitter will then be connected to the network.

The most common cause of incorrect operation is that the Network ID or Join Key are not
set correctly in the device. The Network ID and Join Key in the device must match those
found on the Smart Wireless Gateway. From the Smart Wireless Gateway, click Setup >
Network > Settings to display the Network ID and Join Key. Make sure the setting for "Show

Operation and maintenance

4.2 Power module maintenance

The Smart Power Module contains two “C” size primary lithium/thionyl chloride cells. Each
cell contains approximately 2.5 grams of lithium, for a total of 5 grams in each pack.

Actual power module life can vary dramatically based on operating parameters—including
whether high-resolution data such as vibration waveforms and/or spectra are being
retrieved from the device.

Handling

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 are maintained. Take
care to prevent thermal, electrical, or mechanical damage. Protect the contacts to prevent
premature discharge.

CAUTION!

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

WARNING!

Power module hazards remain even when cells are discharged.

Environmental considerations

As with any battery, consult local, national, and international environmental rules and
regulations for proper management of spent batteries. If no specific requirements exist,
you are encouraged to recycle through a qualified recycler. Consult the materials safety
data sheet for power module-specific information.

Replacement

When the power module needs to be replaced, remove the power module cover and the
power module pack. Replace the pack (P/N MHM-89002, Rosemount P/N 00753- 9220­XXXX, or Rosemount Model # 701PBKKF) and replace the cover. Tighten to specifications
and verify the operation.

Shipping

The unit is shipped without the power module installed. Unless you are specifically
instructed to do otherwise, always remove the power module pack from the unit prior to
shipping.

The U.S. Department of Transportation, International Air Transport Association (IATA),
International Civil Aviation Organization (ICAO), and European Ground Transportation of
Dangerous Goods (ADR) regulate the transportation of primary lithium batteries

The shipper is responsible for complying with these or any other local requirements.
Consult current regulations and requirements before shipping.

Velocity, PeakVue, and temperature

5 Velocity, PeakVue, and temperature

Topics covered in this chapter:

• Overall Velocity

• PeakVue

• Temperature

5.1 Overall Velocity

The Overall Velocity measurement provides a summation of the low-frequency vibration
energy, which indicates fault conditions such as imbalance, misalignment, looseness, and
late-stage bearing problems.

The CSI 9420 uses (lower-frequency) Overall Velocity in conjunction with (higher­frequency) PeakVue to provide a holistic solution across all frequencies while optimizing
the usage of the limited power and bandwidth available in a wireless device. The majority
of developing fault conditions manifest in one or both of these key parameters.

The difference between the standard vibration waveform and the associated PeakVue
waveform is shown in Figure 5-1 and Figure 5-2. Overall Vibration indicates energy from
shaft rotation, expressed in units of RMS velocity per the ISO 10816 standard. PeakVue, on
the other hand, filters out the rotational energy to focus on impacting. Impacting is
expressed in units of Peak acceleration. This indicates key mechanical problems such as
rolling element bearing faults, gear defects, and under-lubrication.

Velocity, PeakVue, and temperature

While PeakVue is very useful for providing an early indication of impact-related faults in
rolling-element bearings, there are many general applications where a lower-frequency
measurement is more appropriate. Also, virtually all vibration analysts are very familiar
with the Overall Velocity measurement and use it as part of their existing vibration
programs. While it may not be possible to obtain a measurement result comparable to the
PeakVue value reported by the CSI 9420 with a non-CSI handheld vibration analyzer, the
Overall Velocity measurement is common throughout the industry and should be easy to
correlate with results from handheld instruments.

There are, however, a number of different methods for measuring and reporting Overall
Velocity, so ensure that the measurement conditions are similar when trying to duplicate
the value reported by the CSI 9420 with a handheld. The CSI 9420 uses ISO 10816, which
defines a measurement bandwidth of 2 Hz to 1 kHz. The ISO 10816 general fault levels at
various turning speeds are shown in Figure 5-3.

General fault levelsFigure 5-3:

Depending on the type of machine being monitored, the values shown in this graph should
be multiplied by the service factors given in Table 5-1.

Figure 5-3 shows the Overall Velocity thresholds for root-mean-square (RMS) velocity in

units of inches per second. Particularly, in digital acquisition systems, it is customary to
measure and calculate with RMS quantities. While it is accepted practice in the industry to
convert between RMS and peak values using the 1.4142 conversion factor, it is not
technically correct to do so except for a pure sinusoidal waveform. For this reason, the CSI
9420 measures, calculates, and reports Overall Velocity in RMS, and it is necessary to
multiply by 1.4142 to get the corresponding peak levels if this is the preferred format.

5.2 PeakVue

PeakVue™ is a patented Emerson technology that is very useful for isolating high­frequency phenomena associated with developing faults, especially in rolling-element
bearings.

The premise for PeakVue is that the high-frequency components are not readily detected
with more conventional measurements such as Overall Velocity, low-frequency energy
(LFE), or digital overall. This is because the low-frequency measurements either average
the energy or provide an energy summation over a relatively large frequency band, and the
relative amount of energy that is typically contributed by the high-frequency components
is quite small. As a result, even large "spikes" are difficult to detect with classic techniques.

The difference in the vibration waveform and the associated measurement for overall
vibration versus PeakVue is shown in Figure 5-5 and Figure 5-6. The overall vibration is well
below the established advisory and maintenance alert levels indicating that the machine is
running well. In contrast, the PeakVue graph shows that the values have increased from
zero, and that they are already crossing the advisory alert level and approaching the
maintenance alert level. This early warning about impending defects is key to maintaining
good machine health.

The PeakVue algorithm isolates the peak energy of interest to provide early indications of
developing bearing faults such as inner and outer race defects, ball defects, and lubrication
problems. Any type of "impacting" fault, where metal is contacting metal, is readily visible
with PeakVue long before there is any significant increase in Overall Vibration. PeakVue is
especially useful for monitoring rolling-element bearings.
