Explosions could result in death or serious injury:
Installation of this transmitter in an explosive environment must be in accordance
with the appropriate local, national, and international standards, codes, and
practices. Please review the approvals section of the CSI 9420 reference manual for
any restrictions associated with a safe installation.
• Before connecting a Field Communicator in an explosive atmosphere, ensure the
instruments are installed in accordance with intrinsically safe or non-incendive
field wiring practices.
Process leaks may cause harm or result in death.
• Install and tighten process connectors before applying pressure.
Electrical shock can result in death or serious injury.
• Avoid contact with the leads and terminals. High voltage that may be present on
leads can cause electrical shock.
NOTICE
The CSI 9420 and all other wireless devices should be installed only after the 1420
Wireless Gateway has been installed and is functioning properly. Wireless devices
should also be powered up in order of proximity from the 1420 Wireless Gateway,
beginning with the closest. This will result in a simpler and faster network installation.
NOTICE
Shipping considerations for wireless products (Lithium Batteries):
The unit was shipped to you without the power module installed. Please remove the power
module pack from the unit prior to shipping.
Primary lithium batteries are regulated in transportation by the U. S. Department of
Transportation, and are also covered by IATA (International Air Transport Association),
ICAO (International Civil Aviation Organization), and ARD (European Ground
Transportation of Dangerous Goods). It is the responsibility of the shipper to ensure
compliance with these or any other local requirements. Please consult current regulations
and requirements before shipping.
The power module pack with the wireless unit 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 pack integrity are maintained. Care
should be taken to prevent thermal, electrical or mechanical damage.
Contacts should be protected to prevent premature discharge.
Power module hazards remain when cells are discharged.
Batteries should be stored in a clean and dry area. For maximum power
module life, storage temperature should not exceed 30 °C.

CONSIDERATIONS
General
Electrical vibration sensors such as accelerometers produce low-level signals
proportional to their sensed vibration. With simple HART configuration, the
CSI 9420 converts the low-level sensor signal to a wireless-enabled signal.
Commissioning
The transmitter can be commissioned before or after installation. It may be
useful to commission it on the bench, before installation, to ensure proper
operation and to become familiar with its functionality. When applicable, make
sure the instruments are installed in accordance with intrinsically safe or
non-incendive field wiring practices. The device will be powered whenever the
power module is installed. To avoid depleting the power module, make sure it
is removed when the device is not in use.
Mechanical
Location
When choosing an installation location and position, take into account the
need for 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, as the pipes or framework may adversely affect
the performance of the antenna.

NOTE:
Prior to sensor connection, it is normal to see alerts related to bias failure.
These alerts will go away once the sensor(s) is installed correctly.
CONNECTION TO THE
WIRED HART
INTERFACE
Unless you purchased your CSI 9420 pre-configured from the factory, it is
necessary to connect to the wired HART interface to define the credentials
required for the device to communicate on your wireless network. If desired,
other device configuration such as sensor type(s) and alert thresholds may
also be defined at this time. The wired HART connection is located on the
bottom of the terminal block in the rear chamber of the device. It is a two-wire,
polarity-independent connection, and it is indicated by “COMM” on the
terminal block label (Figure 2-1).
NOTE:
The power module must be installed to enable the wired HART interface.
NOTE:
The wired HART interface is intended only for configuration. Dynamic
variable, i.e., measured vibration parameters, are not updated when
communicating on the wired interface.
NOTE:
The CSI 9420 does not communicate simultaneously on both the wired and
wireless HART interfaces. As a result, wireless connectivity is lost when you
connect to the wired HART interface for configuration, and configuration
changes are not reflected in a wireless host until connection has been
re-established. To avoid loss of synchronization, it is recommended that hosts
relying on the wireless link be disconnected 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 your 375, you will have to exit AMS
Device Manager and then re-open it after the wireless connection has been
restored in order to see the changes.

CSI 9420
Begin by removing the power module-side housing cover. This will expose the
terminal block and HART communication terminals. Connect the power
module to supply power for configuration. This process is illustrated in Figure
2-2.
Figure 2-2. 375 Field
Communicator Connections
For configuration, the CSI 9420 will receive any HART communications from
a handheld Field Communicator, AMS Device Manager, or other
HART-enabled host. When using a Field Communicator, any configuration
changes must be sent to the transmitter by using the Send key (F2). AMS
Device Manager configuration changes are implemented when the Apply
button is clicked.
NOTE:
The CSI 9420 enters “HART Listen” mode for communication on the wired
interface. When doing so, “HART Listen” is displayed on the optional LCD, if
installed. A finite amount of time is required to enter this mode and the device
is unable to do so during its boot sequence or while performing its real-time
vibration measurement. For this reason, it may be necessary to “retry” the
initial wired HART handshaking sequence. If repeated attempts to establish
wired communication fail, you can force the device into HART Listen made by
removing the front cover and pressing the “CONFIG” button once. Pressing
the CONFIG button a second time causes the device to exit HART Listen
mode. Once the device has entered HART Listen mode, it will remain in this
mode until the CONFIG button is pushed, power is cycled, or no activity is
seen on the wired interface for three (3) minutes.
The basic steps for configuring the CSI 9420 are as follows:

CSI 9420
DEVICE NETWORK
CONFIGURATION
In order to communicate with the 1420 Wireless Gateway, and ultimately the
Information System, the transmitter must be configured to communicate with
the wireless network. This step is the wireless equivalent of connecting wires
from a transmitter to the information system.
Using a Field Communicator or AMS Device Manager, enter the Network ID
and Join Key so that they match the Network ID and Join Key of the gateway
and other devices in the network. If the Network ID and Join Key are not
identical, the transmitter will not communicate with the network. The Network
ID and Join Key may be obtained from the 1420 Wireless Gateway on the
Setup>Network>Settings page on the web server.
The final device network configuration piece is the Update Rate. This by
default is 30 minutes. This may be changed at commissioning, or at any time
via AMS Device Manager or the 1420 Wireless Gateway’s web server. The
Update Rate should be between 60 seconds and 1 hour for the 2.4 GHz CSI
9420. For the 900 MHz CSI 9420, the Update Rate is 60 seconds and around
18 hours.
When device configuration is completed, exit HART listen mode and replace
the power module cover. Tighten the cover to the proper tension for safety
approvals.
To access the Network Settings using a 375 Field Communicator, enter the
following Fast Key Sequence: 1, 1, 7.
DEVICE
CONFIGURATION
OPTIONS
The CSI 9420 has a number of configuration options that affect how the
device operates. These settings control such things as how often the
measuremnt results are reported, how these results are reported, the number
and type of sensor(s) installed, and how and when alerts are generated. The
default configuration and process variable mappings is shown in Table 2-1.
The possible sensor configurations are shown in Table 2-2.

NOTE
The word “sensor” refers to both an accelerometer and an accelerometer with
embedded temperature. The word “accelerometer” refers to a sensor that
measures only acceleration.
Each of the CSI 9420 signal inputs uses accelerometers to make vibration
measurements. Alternately, an accelerometer with embedded temperature
may be used.
Sensor Sensitivity
Each sensor was characterized at the factory to determine the precise
sensitivity of the sensor. This information is included with the sensor in the
form of a certificate, and may be cross-referenced with the serial number as
shown in Figure 2-5 on page 2-10.

ALARM LEVELS
Fast Keys
1, 1, 5
The CSI 9420 sets HART status bits to indicate when measured values
exceed the configured thresholds. Each measured value has three (3) levels:
Advisory, Maintenance, and Failed that may be set independently. These
thresholds are preconfigured at the factory to reasonable generic values for
single-stage, electric motor-driver equipment trains operating at line
frequency. The default alert levels for vibration are shown in Table 2-4.

information on how to set the thresholds refer to Appendix C: Velocity,
PeakVue®, and Temperature, or consult with a vibration specialist.

Reference Manual
MHM-97408, Rev. 2
June 2008
CSI 9420
If all else fails, one “rule of thumb” for vibration is to examine the current level
at which the equipment is operating. Then, assuming the equipment is in
good working order, set the Advisory level at 2x the current value (or at a
minimum of 0.05 in/sec. 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/sec., set the
Advisory threshold at 0.2 in/sec., the Maintenance threshold at 0.4 in/sec.
and the Failed threshold at 0.8 in/sec. While Emerson does not condone this
type of vibration program, it can provide a starting point when no other
information is available.
The default alert thresholds for temperature correspond closely to a generic
open drip-proof (ODP) motor with class F insulation and a service factor of
1.15, operating at an ambient temperature at or below 40 °C and at an
altitude at or below 1000 meters. These values are also reasonable
thresholds to use when there is no knowledge of the process, the type of
machinery, or the operating environment. Refer to Appendix C: Velocity,
PeakVue®, and Temperature for more information. The default temperature
levels are shown in Table 2-5.

NOTE:
When any measured process parameter (Velocity, PeakVue, or Temperature)
exceds the configured Advise, Maintenance, or Failed threshold, this causes
an “Advisory” indications on a screen that is viewed from AMS Device
Manager (or other graphical host). This indicator itself does not set a status

CSI 9420
MOUNTING
Introduction
To reduce power consumption and increase power module life, the CSI 9420
uses a special low-power sensor. This sensor is available with or without
embedded temperature. Refer to Appendix A: Specifications and Reference
Data for a complete list of available sensor options.
Please contact your local sales representative for detailed ordering
information.
To maintain mechanical isolation of the sensor a Remote Mount configuration
is required. For Remote Mount, the sensor is mounted separately from the
CSI 9420 housing, then connected to the CSI 9420. Although not required for
all installations, it is common to run the cable from the sensor to the housing
through conduit.
Operating Limits
Each of the CSI 9420 signal inputs uses accelerometers to make vibration
measurements. Alternately, an accelerometer with embedded temperature
may be used.
NOTE
The word “sensor” refers to both an accelerometer and an accelerometer with
embedded temperature. The word “accelerometer” refers to a sensor that
measures only acceleration.
The operational ranges for the sensors are shown in Table 3-1.

N/A
The accelerometers require a DC bias. The CSI 9420 device provides the
necessary bias and measures it to verify correct sensor operation. The
nominal bias voltage is 2.5 volts. If the bias voltage is outside of the 2 - 3 volt
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.
GENERAL SENSOR
HANDLING
INSTRUCTIONS
Each sensor requires a standard 1/4” - 28 mounting location. Detailed
mounting instructions are provided in subsequent sections of this manual.
Do not drop, hammer, or impact sensor housing before, during, or after installation.
Do not exceed specified torque when tightening a stud-mounted sensor. Over-tightening a
sensor will damage the sensing element and void the manufacturer’s warranty.

Reference Manual
MHM-97408, Rev. 2
June 2008
CSI 9420
Although the integral cable has built-in strain relief, do not use excessive force
when pulling cable. No more than 5-lbs. of force should be exerted directly on
the senor connection during installation. It is recommended that the cable be
secured to the machine near the point of sensor installation if possible.
Do not exert more than 5-lbs. 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 junction box, 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 causing
strain at the sensor/cable connection.
SENSORS
Preferred Method of
Mounting Sensors
Drill and Tap (Stud Mount)
The preferred method of mounting sensors to a machine is the drill and tap
(stud mount) method. Drill and tap mounting is preferred because it provides
increased reliability, improved frequency response, and increased signal
sensitivity.
This method of mounting to a machine is:
1.
Drill into the machinery.
2.
Tap the hole
3.
Insert the mounting stud.
4.
Directly mount the sensor to the surface of the machine.
Epoxy Mounting
If the machinery cannot have a hole drilled into it, the epoxy mounting method
is acceptable, though it is less reliable and the sensor performance is
degraded at high frequencies. The epoxy mounting method is:
1.
Glue a mounting pad to the machinery.
2.
Insert the mounting stud.
3.
Attach the sensor to the pad.
Tools and Supplies
Below is a list of required tools and parts necessary to install the sensors.

Prepare the spot face and end milling tool by setting the drill bit depth
to a minimum of 0.325 inches (325 mils).
2.
Using the wire brush and plant-approved cleaner, clean and degrease
the surface area.
3.
Keeping the spot face and end milling tool perpendicular to the
machine surface, drill into mounting location until face has a minimum
finish of 63 micro inches (.063 mils). This will require the spot facing
tool to remove approximately 0.04 inches (40 mils) from the face. The
surface should be smooth to the touch with no noticeable
irregularities. The process is illustrated in Figure 3-2.
NOTE
If the spot face is not uniform on all sides, this is an indication that the spot
face tool was not perpendicular to the mounting surface (Figure 3-3) and the
resulting surface will not allow the sensor to be mounted properly.

NOTE:
To maximize power module life, it is recommended that you disable the LCD
when not in use. The LCD consumes very little power. Displaying information
on the LCD and leaving it active for a sufficient amount of time for a human
being to read it, however, requires the CSI 9420 to remain “awake” almost
twice as long. Depending on the update rate, disabling the LCD can increase
the life of the power module by as much as 40 percent.
If your CSI 9420 was purchased without the optional LCD, and you wish to
add this later, an upgrade kit is available. Contact your Emerson sales
representative for more information.
Ground the Transmitter
The transmitter will operate 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.

The electronics enclosure should be grounded in accordance with local and
national installation codes. This can be accomplished via the base
connection, via the internal case grounding terminal, or via the external
grounding terminal.

Instructions and procedures in this section may require special precautions to
ensure the safety of the personnel performing the operations. Information that
potentially raises safety issues is indicated by a warning symbol ( ). Please
refer to the following safety messages before performing an operation
preceded by this symbol.
Warnings
Failure to follow these installation guidelines could result in death or
serious injury.
•
Make sure only qualified personnel perform the installation.
Explosions could result in death or serious injury.
•
Before connecting a 375 Field Communicator in an explosive atmosphere, make
sure the instruments are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
•

appropriate hazardous locations certifications.
Electrical shock could cause death or serious injury.
•
Use extreme caution when making contact with the leads and terminals.
NOTE
The CSI 9420 and all other wireless devices should be installed only after the
1420 Wireless Gateway has been installed and is functioning properly.
Wireless devices should also be powered up in order of proximity from the
1420 Wireless Gateway, beginning with the closest device to the 1420. This
will result in a simpler and faster network installation.
VERIFY OPERATION
www.mhm.assetweb.com
Operation can be verified in three locations, at the device via the Local
Display, using the 375 Field Communicator, or at the Gateway via the 1420

POWER MODULE
REPLACEMENT
Expected power module life is four (4) years at reference conditions.(1)
When power module replacement is required, remove the power module
cover and remove the power module pack. Replace the pack (part number
MHM-89002 or Rosemount P/N 00753-9220-XXXX) and replace the cover.
Tighten to specification and verify operation.
Handling Considerations
The power module pack with the wireless unit contains 2 “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 are
maintained. Care should be taken to prevent thermal, electrical or mechanical
damage. Contacts should be protected to prevent premature discharge.
Use caution when handling the power module pack. The power module pack
may be damaged if dropped from heights in excess of 20 feet.
Power module hazards remain when cells are discharged.
Environmental Considerations
As with any battery, local environmental rules and regulations should be
consulted for proper management of spent batteries. If no specific
requirements exist, recycling through a qualified recycler is encouraged.
Consult the materials safety data sheet for power module specific information.
Shipping Considerations
The unit is shipped to you without the power module installed. Unless
specifically instructed to do otherwise, remove the power module pack from
the unit prior to shipping.
Primary lithium batteries are regulated in transportation by the U.S.
Department of Transportation, and are also covered by International Air
Transport Association (IATA), International Civil Aviation Organization (ICAO),
and European Ground Transportation of Dangerous Goods (ARD). It is the
responsibility of the shipper to ensure compliance with these or any other
local requirements. Please consult current regulations and requirements
before shipping.

NOTES:
1.
Measurement accuracy is the absolute accuracy of the measurement
relative to a known, calibrated excitation.
2.
Typical measurement accuracy represents the expected performance
operating under steady-state conditions (constant temperature at 20
°C with no external interference) for a mid-band excitation (nominally
1 g at 100 Hz). This variation includes the frequency response of the
electronics and the sensor.
3.
Worst case measurement accuracy represents the worst-case
performance over the entire temperature range, across all
frequencies and amplitudes, and in the presence of high-intensity
transient EMI.
Frequency response variability:
RMS velocity:
• +/- 0.4 dB from 5 Hz to 1000 Hz
• +/- 2.0 dB from 2 Hz to 1000 Hz.
PeakVue:
•
+/- 0.4 dB from 2500 Hz to 20 kHz
•
+/- 1.0 dB from 1 kHz to 25 kHz.
Temperature:
•
+/- 4° C.
Sensor variability:
• Temperature coefficient: 0.1% per °F; 0.18% per °C (+/1.4 dB)
• EMI/transient susceptibility (2.4 GHz only): +/- 1.4 dB
under worst-case interference(per EN 61326).

OVERALL VELOCITY
The Overall Velocity measurement provides a summation of the
low-frequency vibration energy, which is indicative of fault conditions such as
imbalance, misalignment, looseness, and late-stage bearing problems.
The CSI 9420 uses (low-frequency) Overall Velocity in conjunction with
(high-frequency) PeakVueTM to provide a holistic solution across frequency
while optimizing the usage of the limited power and bandwidth available in a
wireless device. The majority of developing fault conditions will be manifested
with a monotonic increase in one or both of these key parameters.
The difference in the vibration waveform and the associated measurement for
Overall Vibration versus PeakVue is depicted conceptually in the illustrations
below. Overall Vibration provides an indication of the total low-frequency
energy in the waveform. PeakVue, on the other hand, provides an indication
of the maximum excursion in the waveform, which is how indications of many
developing bearing faults are first manifested.
Figure C-1. Overall Vibration
(left) and PeakVue (right) charts.
While PeakVue is extremely useful for providing an early indication of
impact-related faults in rolling-element bearings, there are many more general
applications where a low-frequency measurement is more appropriate.
Furthermore, virtually all vibration analysts are very familiar with the Overall
Velocity measurement and use it as part of their existing vibration programs.
As a result, 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 ubiquitous
throughout the industry and should be easy to correlate with the results from
handheld instruments.

There are, however, a number of different methods for measuring and reporting
Overall Velocity, so it is important to ensure that the measurement conditions
are similar when trying to duplicate the value reported by the CSI 9420 with that
of 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 depicted graphically in the figure below.
Figure C-2. General Fault levels
Depending on the type of machine being monitored, the values shown in this
graph should be multiplied by the service factors given in the following table:

It is important to note that the Overall Velocity thresholds in the graph are for
root-mean-square (RMS) velocity in units of inches per second. Particularly in
digital acquisition systems, it is customary to make the measurement and do the
calculation with RMS quantities. While it is accepted practice in the industry to
convert between RMS and peak values using the well-known 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.
The default levels in the CSI 9420 for ADVISE, MAINT, and FAILED alerts are
0.14 in/sec RMS, 0.35 in/sec RMS and 1.0 in/sec RMS, respectively.

PEAKVUE
CSI 9420
PeakVue is a patented technique that is extremely useful for isolating
high-frequency 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 depicted conceptually in the illustrations
below. Overall Vibration provides an indication of the total low-frequency
energy in the waveform. PeakVue, on the other hand, provides an indication
of the maximum excursion in the waveform, which is how indications of many
developing bearing faults are first manifested.
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.
Based on years of experience with this technology, Emerson Process
Management has developed for PeakVue alarm levels, which are illustrated in
the graph below.

levels diagram.

Again, keep in mind that these are generic limits.They are provided as a
starting point and these values (for a 3600 RPM machine) are used as the
default alert thresholds by the vibration transmitter.
Utilizing the embedded PeakVue technology, the CSI 9420 identified
developing problems at a couple of test sites during early field trials. In both
cases, the problem was not visible with conventional low-frequency analysis.
Example data from one of the sites is provided below. Notice in this example
that the velocity measurement is indicating less than 0.1 inches/second. The
PeakVue trend, however, indicates high-frequency vibration that is regularly in
excess of 6 g’s.
The user at this location removed the defective bearing, and the photographs
below clearly show the developing problem that was the source of the
impacting. After replacing the bearing, the PeakVue vibration is significantly
reduced, indicating that the problem has been resolved. This is clearly shown
in the data following the photographs.

TEMPERATURE
CSI 9420
The levels at which to set temperature alerts depend on a variety of factors
including the specific process, the operating environment, and the
characteristics of the equipment being monitored. This discussion provides
some generic guidelines, given some knowledge of the variables involved, for
setting the thresholds for your specific CSI 9420 installation. Keep in mind,
though, that the generic methodologies described here are no substitute for
first-hand knowledge of your plant. If, for example, you know that you have
problems when a temperature exceeds a particular value, then set your
thresholds accordingly rather than following these generic guidelines.

Reference Manual
MHM-97408, Rev. 2

CSI 9420
In general, the best way to detect a developing fault related to temperature is
to look for an increase in the temperature, relative to ambient, over time. This
implies that, for reliable alerting, the thresholds should change as ambient
temperature changes. In practice, this can be difficult to do because it
requires the operator constantly to monitor the ambient temperature and
adjust the alert levels accordingly. It is customary, therefore, to pick an
"average" ambient temperature (that is generally seasonal for outdoor
installations) and choose fixed thresholds based on this average. Be advised,
however, that there are issues with this methodology (i.e., it does not work
well) in areas with large variations in ambient temperature.
Thresholds may also be selected based on some absolute temperature limit.
In practice, this is much easier to maintain but it is not as effective at detecting
early failures as relative monitoring.
"Relative" Temperature
Monitoring
The recommended generic guidelines for setting the thresholds based on the
relative change are:
•
TAdvise = 10 °C increase
•
TMaintenance = 15 °C increase
•
TFailed = 20 °C increase
For example, assume ambient temperature is 25 °C. When operating at
steady-state, you have determined that the normal temperature at this point
on your equipment is 55 °C. So, your "baseline" relative difference is 30 °C.
Using the above guidelines, you should choose the Advise, Maintenance, and
Failed levels for a difference of 40 °C, 45 °C, and 50 °C, respectfully.
Assuming the ambient temperature is constant at 25 °C, this means the
thresholds become 65 °C, 70 °C, and 75 °C for Advise, Maintenance, and
Failed, respectively. Then, as the ambient temperature changes, the
thresholds should be changed accordingly (e.g., a 5 °C increase in ambient
temperature raises the alert thresholds by 5 °C).
Absolute Temperature
Monitoring
For monitoring a driven component (e.g., a pump or a fan), there are no
generic rules for determining the default levels without some a priori
knowledge of the steady-state baseline (good) value. In general, the Advisory
level should be set about 10 °C to 20 °C above this baseline, with the
Maintenance level about 10 °C above Advisory and the Failed level about
10 °C above Maintenance.
There are equations that define the suggested generic thresholds for
monitoring motor (driver) temperature. These are based on characteristics of
the motor as well as knowledge of the ambient temperature.
The first step is to determine the estimated winding temperature, which is
dependent on the following variables:
•
Insulation type
•
Motor type
•
Ambient temperature
•
Altitude
The estimated winding temperature, TW, is the rise temperature, Trise, for the
appropriate type of motor adjusted for high ambient temperature (Ta) effects.

Use the following relationships to determine Trise.
•
Trise = 65 °C + serv_fact_temp; for class A insulation
•
Trise = 85 °C + serv_fact_temp; for class B insulation
•
Trise = 110 °C + serv_fact_temp; for class F insulation
•
Trise = 130 °C + serv_fact_temp; for class H insulation
•
Trise = 150 °C + serv_fact_temp; for class N insulation
serv_fact_temp =
•
5 for service factor of 1.15 or greater
•
-5 for either open or TEFC motors, and service factor of 1.0
•
0 for either totally enclosed non-ventilated (TENV) motors or motors
with encapsulated windings, and service factor of 1.0
If elevation > 3300 ft (1000m) then,
Trise = Trise [1-((altitude (units of ft) - 3300)/33,000)]
If Ta is less than or equal to 40 °C (or unknown), then
Tw = Trise + 40 °C
If Ta > 40 °C, then
Tw = Trise + 40 °C - (Ta - 40 °C)
Again, if Ta is unavailable assume Ta is less than 40 °C.
Next, calculate the generic alert thresholds based on the estimated winding
temperature, TW.
Tf_fault = Fault level alarm temperature (°C) of the motor skin (frame)
Tf_maintenance = Maintenance level alarm temperature (°C) of the motor skin
Tf_advisory = Advisory level alarm temperature (°C) of the motor skin

For open drip proof (ODP) motors:
Tf_fault = 35.5366*Ln(Tw) - 91.1571
