1. System Description

The 2201 Monitoring System is a machinery monitoring system designed by

Bently Nevada to operate in an Allen-Bradley 1771 rack and interface to an Allen-
Bradley PLC either directly (in local chassis) or indirectly through a remote I/O
adapter (in remote chassis). This figure shows a diagram of the system with only

a Four Channel Monitor installed.

2201 Monitoring System Operation Manual
Notice:
If your system contains 2201/06 Low Speed Monitors, installation and
operation will differ from the procedures in this manual. Refer to
manual 131699-01 for information about the 2201/06 monitors.

The system is regarded as an intelligent I/O module by the PLC and uses +5 volt
power provided by an Allen Bradley Supply. The communication interface
between the PLC and the system is controlled by the PLC and is done by means of
block transfers of data (read and write) and single data transfers (read only). Each
system consists of a System Monitor, from one to six monitor modules, and a
backplane. A Four Channel Monitor is a universal element that has four general
purpose monitoring channels. Each channel can be configured via the PLC to
monitor thrust, radial vibration, velocity, and acceleration, and can provide two
levels of alarm. (The function of individual channels in a Four Channel Monitor
depends on which option you choose. See Section 1.1). This figure summarizes
some of the features of the System Monitor and the Four Channel Monitor.

Software called TestVU is available to help you troubleshoot your system. The
software runs on an IBM PC or compatible machine and displays current values,
alarm setpoints, system and channel configurations, and various other data. If
faults develop in the 2201 Monitoring System, TestVU details the nature of the
fault. TestVU also lets you store data on a disk or print it as a text file. Although
TestVU provides detailed information about the system operation, it does not play
any role in the actual monitoring and the 2201 system could operate without it.
Configuration Software is also available to help you configure the 2201 system.
This software runs on an IBM compatible PC and lets you display current channel
data and configure the system.
Both these programs are included with the 2201 software, part number 2201/04.

1.3 Features and Functions of the 2201 Monitoring

System
The 2201 Monitoring System can have up to 24 channels of monitoring by
installing up to six monitor modules and connecting the appropriate
displacement (proximity) and/or seismic (velocity, Velomitor and Accelerometer)
transducers to their inputs.
The 2201 System Monitor also provides for two Keyphasor transducers. These
inputs are used by the 2201/06 Low Speed Monitors.

Notice:
2201/06-01 Low Speed Monitors provide other types of monitoring. Refer
to 2201 Monitoring System with 2201/06-01 Low Speed Monitors manual,
part number 131699-01 for information.

1-4
 Setting Programmable Options

1.3.1 Types of Monitoring

The system can monitor thrust, radial vibration, velocity and acceleration. When
2201/06 Low Speed Monitors are used, other types of monitoring are available.
THRUST is the average position, or change in position, of a rotor in the axial
direction with respect to some fixed reference. Normal thrust direction can be
towards or away from the probe face.
RADIAL VIBRATION is the dynamic motion of the shaft in a direction perpendicular
to the shaft centerline.
VELOCITY is measured by a mechanically activated velocity transducer or a
Velomitor and is used to evaluate the response of the machine housing and other
structures.
ACCELERATION is measured with piezoelectric Accelerometers and is typically
used to evaluate the high frequency response of the machine casing or bearing
housing.

1.3.2 Signal Conditioning

You can condition the signals in the 2201 Monitoring System by setting high and
low pass filters, integration and signal detection for RMS or peak.
FILTERS are available on channels 3 and 4 of 2201/03-02 monitors and all
channels of 2201/03-03 monitors except when the channel is configured for
thrust position monitoring. The filters can be low pass, high pass, or band pass to
filter a specific frequency band of a signal. All filter characteristics are four pole
Butterworth except on channels one and two of the 2201/03-03 monitor. These
channels have two pole Butterworth filter characteristics. The corner frequency
of these filters can be selected from a wide choice of available frequencies and
are programmed using the PLC block transfer write.
INTEGRATOR circuits electronically integrate the signals from seismic transducers
and convert acceleration signals to velocity or velocity signals to displacement.
Attempting to integrate signals from displacement transducers causes a
configuration error.
RMS SIGNAL LEVEL is a measure of the energy contained in the transducer signal.
Unlike a peak to peak measurement, RMS measurement can mask low energy
signal transients that may indicate the condition of a machine. RMS detection is
only used to measure velocity or acceleration.
PEAK SIGNAL LEVEL is a measure of the absolute value of the peak of the signal
measured from the average signal level.
PEAK TO PEAK SIGNAL LEVEL is the difference between the most positive and
negative values of a signal.

1-5
2201 Monitoring System Operation Manual
GAP VOLTAGE is the value of the negative dc output signal of a proximity probe
that is proportional to the distance between the face of the probe tip and the
observed surface.Alarms and Alarm Setpoints
ALARM SETPOINTS in the 2201 system are set by block transfer writes from the
PLC. Thrust channels have four alarms - two for under alarms and two for over
alarms. Other channels have two alarms - Alert and Danger.
ALARM TIME DELAY is the minimum time a signal must continuously exceed an
alarm setpoint before the alarm is set.

1.3.3 Buffered Outputs

BUFFERED OUTPUTS of all transducer input signals are available at the front panel
co-axial connectors. These connectors may be used to connect external
diagnostic equipment. With displacement transducers, the buffered signal
always goes directly to the connector. With seismic transducers, the buffered
signal can either go directly to the connector (direct) or through the integrator
and/or filter circuits and then to the connector (conditioned). Some restrictions
apply to conditioned buffered signals. (See Section 4.2.6).
KEYPHASORS, the System Monitor accepts up to two Keyphasor transducer inputs
for use with 2201/06-01 Low Speed Monitors. These signals are buffered and
available at two co-axial connectors on the front of the System Monitor to
connect to external diagnostic equipment.

1.3.4 OK Circuitry
CHANNEL OK indicates that the channel has passed all monitor, system, and
channel self-tests and that it is correctly configured. OK also indicates that the
transducer input signal is within the upper and lower OK voltage limits.
TIMED OK/CHANNEL DEFEAT prevents faults in transducer wiring and certain
types of transducer faults from causing spurious alarms. When Timed
OK/Channel Defeat is enabled, the transducer must be OK for 30 seconds
following a not OK condition before monitoring is resumed. This option will defeat
alarms when the channel is not OK.

1.3.5 Self-Tests
Four Channel Monitors have three levels of self-test; Power-up, Cyclic, and Self-
Test with Calibration.
• Power-up self-test is performed automatically upon power-up and detects
hardware problems in the 2201 system.
• Cyclic self-test is performed continuously during monitor operation. If the
test finds an error it will disable one channel, the Four Channel Monitor, the
System Monitor, or the entire 2201 system depending on the severity of
the error.

1-6
 Setting Programmable Options
Self-Test with Calibration is performed when a full block transfer write is
used to configure the 2201 system. This self-test detects incorrect
configuration and hardware problems. The test also calibrates the system
and can take up to two minutes to complete depending on the number
and type of Four Channel Monitors in the system. If no configuration is
received within 60 seconds of power-up, the 2201 system will load an
internal default configuration. This will cause a Self-Test with Calibration.
(See Section 4 for a description of the system default configuration).

Notice:
When using the 2201 System with the PLC chassis configured for half-
slot addressing, the slot to the left of the 2201 System Monitor must not
contain any other modules which use High Density Discrete Data
(including power supplies). Discrete Data from the 2201 System Monitor
may be invalid if this requirement is not met.

2.3 Four Channel Monitor Programming

A 2201/03-02 monitor has a Two Channel Seismic plug-in board that lets you
connect two seismic transducers to channels 3 and 4 for integration and RMS
conversion, and filter signals from two seismic or radial vibration transducers. A
2201/03-03 monitor has a Four Channel Seismic board that lets you connect four
seismic transducers and filter the signal from four seismic or radial vibration
transducer inputs.
Each seismic board has several user-programmable options which can be set
without disassembling the monitor. Change the options by removing and
installing jumpers on the bottom edge of the seismic printed circuit board.

3. Installing the System

Application Alert
Remove power from the 1771 I/O chassis before installing or removing
any part of the 2201 Monitoring System. Failure to remove power from
the chassis will damage equipment or degrade performance.

Application Alert
Using more than two High Frequency Accelerometers with a Four
Channel Monitor may cause the monitor to fail because of excessive
transducer supply requirements. Connect no more than two
Accelerometers to a single Four Channel Monitor.

Use this approach to install a 2201 Monitoring System in an Allen-Bradley 1771

Rack:
• Check the power supply requirements.
• Check that other modules in the rack are compatible with the 2201
system.
• Install the 2201 Monitoring System backplane.
• Install the System Monitor and the Four-Channel Monitors.
• Ground the system.
• Connect the inputs from transducers.

Notice:
If you are also using 2201/06 Low Speed Monitors, refer to manual
131699-01 for details of power supply requirements, wiring, and
installation for this type of monitor.

3-1
2201 Monitoring System Operation Manual
3.1 Checking the Power Supply Requirements
Before you install the 2201 Monitoring System, be sure that the Allen-Bradley
chassis has sufficient power for the monitoring system and other modules in the
chassis. To calculate the chassis power supply requirement, use the following
table to work out the monitoring system power requirement and add it to the
total power requirement of the other modules installed in the chassis.

3.2 Checking that Other Modules in the Rack are

Compatible with the 2201 System
Take the following precautions to ensure that the 2201 system will operate
properly with other modules in the Allen-Bradley 1771 rack:
• When using PLC 2-slot addressing, the 2201 Monitoring System must
begin in the left hand slot (slot 0) of any group in the rack.
• When using PLC half-slot addressing, there must be no high density
modules in the slot to the left of the 2201 System Monitor.
• Since the inputs to the 2201 Monitoring System are low voltage analog
signals, locate the system away from ac modules or high voltage dc
modules wherever possible to minimize the effects of radiated electrical
noise.

3-2
 Installing the System
• Connect the 2201 Monitoring System to a single earth point. Read the
important earthing guidelines at the end of this section very carefully
before attempting to operate the system.

3.3 Installing the 2201 Monitoring System Backplane

The 2201 Monitoring System has its own backplane that mounts inside the PLC
chassis in front of the PLC backplane. The System Monitor and all the Four
Channel Monitors connect to both of these backplanes. The monitoring system
uses the monitoring system backplane to communicate data between the
System Monitor and the Four Channel Monitors.
The monitoring system backplane is mounted on one or more backplane
retention plates. Mount these plates between two adjacent PLC backplane
connectors by using one of the following procedures. The procedure to use
depends on the connector used on your PLC backplane. If one procedure does
not work, use the other one.

3.3.1 Mounting a Backplane on a Type 1 PLC

1. Place the retention plate over the PLC
connectors as shown.

3-3
2201 Monitoring System Operation Manual

2. Lower the left side of the plate and

insert the fingers under the PLC
connectors.

3-4
 Installing the System
3. Twist the other side so the plate
lies flat on the PLC backplane
surface and the right hand
edges are inserted under the
adjacent PLC connectors.

The plate stays loosely in place

until the monitoring backplane
is installed and its screws are
tightened to the plate.

3-5
2201 Monitoring System Operation Manual
3.3.2 Mounting a Backplane on a Type 2 PLC
1. Place the plate over the PLC
connectors so that the threaded
inserts of the plate face you, the
fingers are on the left hand side,
and the notch is resting on the
PLC lower connector.
2. Lower the top end of the plate
and push it under the PLC upper
connectors.
3. Slide the bottom end of the plate
under the PLC lower connectors
until the notch touches the lower
connector on the PLC.

3-6
 Installing the System

3.3.3 Attaching the 2201 Backplane to the Retention Plates

The 2201 backplane is firmly retained on the retention plates when the screws
are tightened to the plates. The 2201 system backplane comes in 2, 3, 4, 5, 6, and
7 position versions. The System Monitor occupies the left position and the Four
Channel Monitors occupy the other positions. You need to install one retention
plate for each Four Channel Monitor in your monitoring backplane. This figure
shows the retention plates and backplane for a four position 2201 Monitoring

System.

3-7
2201 Monitoring System Operation Manual

3.4 Installing the System Monitor and the Four Channel

Monitors
The system will not operate without a System Monitor. The System Monitor has a
full-length connector and can only be plugged into the left-most position of the
monitoring system backplane. Make sure the System Monitor is correctly located
in the card guides and that it is securely inserted into the backplane connectors.
Monitor modules (Four Channel Monitors and Low Speed Monitors) have half-
length connectors and can be located in any position in the monitoring system
backplane except the left-most position which is reserved for the System Monitor.
Make sure the monitor is correctly located in the card guides and that it is
securely inserted into the backplane connector.
Once all the modules have been correctly installed in the rack, lower the latch bar
to secure them in place.

This section shows how to connect transducers to the 2201 System Monitor and
Four Channel Monitors with or without zener barriers and lists some important
guidelines for grounding the system.

3.5.1 Wiring Vibration Transducers

Each Four Channel Monitor comes with a wiring connector for connecting four
transducers (displacement and/or seismic) to the monitor. The two figures on
page 3-8 show the connections for three different transducers with and without
zener safety barriers. Notice that on both these figures the fourth channel is not
used.

3.5.2 Wiring Keyphasor Transducers

Two Keyphasor transducers can also be connected to the System Monitor. The
two figures on page 3-9 show how to connect Keyphasor transducers to the
System Monitor with and without safety zener barriers.

3.5.3 Important Earthing Guidelines

Warning

3-8
 Installing the System

Failure to follow these earthing guidelines could result in the 2201

system to float without reference. This may cause high voltage to be
present which can cause shock, burns, or death.

Since the 2201 Monitoring System is not earthed internally, it must be terminated
to an external earth ground. The System Monitor, all monitor modules, and all
field wiring shields must be individually connected to a single earth point. The
cable used to connect the System Monitor and all monitor modules to the earth
point must be a wide, flat, braided wire or a stranded cable with a large cross
sectional area. The single earth point could be an Allen-Bradley chassis, safety
zener barrier earth rail, or other suitable point such as a cabinet earthing point.

3.6 Notes on Wiring and Installation

1. Wiring recommendations:
Solid or stranded cables, with braid or foil shield and insulating sheath
should be used. Cross sectional area and number of wires in the cable
depend on transducer type used:

Type of Channel Recommended Wiring

No. Wires AWG mm2

Acceleration and 3 14 to 18 0.8 to 2

vibration.

Thrust. 3 18 to 22 0.32 to 0.8

Velocity. 2 18 to 22 0.32 to 0.8

2. Shields are joined as shown, terminating at safety zener barrier ground.
Shields should be insulated.
3. Use MTL safety barrier .
4. Safety zener barriers are mounted on the barrier rail. The barrier rail is the
system ground and is used to terminate the potential equalization bus.
The total earth loop impedance must not exceed 1 Ω.
5. Maximum total cable length between the monitor and the transducer
must not exceed 1000 feet (305 meters).
6. The interface module case must be electrically isolated from earth ground.
The electrical isolation must be 500 Vac minimum. Bently Nevada
isolation kit, part number 19094-01, may be used to satisfy the isolation
requirement.
7. Unless 3300 Proximitors are used, the Proximitor case must be electrically
isolated from earth ground. The electrical isolation must be 500 Vac
minimum. Isolation kit, part number 19094-01, may be used to satisfy the
isolation requirement.
8. Safety zener barriers located in division 2 or zone 2 hazardous areas must
be installed in NEMA 4 or IP 54, or otherwise approved protective housing.

 Configuring the System

4. Configuring the System

Before the 2201 Monitoring System can operate properly, the components of the
system need to be defined and certain options need to be set by using a process
called configuration. This section shows how to configure the 2201 system by
describing the two methods for configuring the system and then listing all the
parameters to be configured. Both methods of configuration involve writing a
PLC ladder logic program to control the sending of the Block Transfer Writes to
the 2201 System Monitor.

Notice:
This manual is used for Four Channel Monitors only. If your system
contains Low Speed Monitors, use 2201 Monitoring System with
2201/06-01 Low Speed Monitors manual, part number 131699-01, as a
reference for your ladder logic program and configuration data.

4.1 Methods for Configuring the System

We recommend that you use Bently Nevada Configuration Software (part number
2201/04-01 or -02) to build the data table for the 2201 system. If you use this
software, use the information in this section of the manual as a reference and
configure the system in English rather than binary terms. This software is
provided with the System Monitor or may be ordered separately.
The second method for configuring the 2201 Monitoring System is using the PLC
software to prepare up to 29 16-bit words of digital data for each Four Channel
Monitor. The System Monitor uses this data to set options. If you use this method,
use the information in this section to determine the function of the bits in these
data tables.
Following system configuration, it is recommended that TestVU Software is used
to make a record of the current configuration. TestVU Software will prepare both
printed reports and disk files recording the system configuration.

Application Alert
If your system contains both Four Channel Monitors and Low Speed
Monitors, the BTW’s for the Four Channel Monitors are still formatted as
described in this section. For information regarding BTW length and
format of Low Speed Monitors please refer to manual 131699-01.

4.1.1 Default Configuration

If the 2201 system does not receive a configuration within one minute after
power-up, the System Monitor will load a default configuration. This configuration
can help troubleshoot and test the system. A full Block Transfer Write will clear
the default configuration. The default configuration is as follows:

4.1.2 Using the PLC Software to Configure Block Transfer Writes

BLOCK TRANSFER WRITES configure the 2201 system using a series of block
transfers of data from the PLC to the System Monitor. These blocks of data are
known as Block Transfer Writes (BTW). One BTW is required for each of the Four
Channel Monitors in a system. Six BTW’s are needed to configure a full 24
channel, 6 monitor system. Each BTW consists of a maximum of twenty-nine

4-2
 Configuring the System
words of data. Each word is sixteen bits long. You can configure a monitor by
transferring a short block transfer write or a full block of data.

SHORT BLOCK TRANSFER WRITES are between one and nine words long. These
nine words are Word 0 through Word 8. After a short BTW the monitor will not
perform a self-test. Use the short BTW to change monitor setpoints and thrust
channel zero voltages without causing the system to perform a self-test and
calibration which can take up to two minutes to complete.
FULL BLOCK TRANSFER WRITES are a full block of data that contains all twenty-
nine words of data. Use a full BTW to initiate a monitor self-test and calibrate the
system.
The full BTW data format is described in Appendix A.

4.1.3 Using the Configuration Software and a PC

The configuration software runs on an IBM PC or compatible machine connected
to the PLC as a programming terminal. The configuration software manual
describes how to install and run the configuration software.

4.2 List of Configuration Parameters

Configuration parameters define the components of the 2201 system and set
certain options that govern how the system will operate. The parameters that
follow are listed by the BTW word where the bit(s) for the parameter are located.
The full BTW data format is described in Appendix A. Some of these parameters
have valid values which change according to the transducer type in use.
Appendix F contains tables which show the valid values of these parameters.

Notice:
1. All alarms have a hysteresis of 0.5 % of current full-scale range.
2. Words one through four specify the Alert and Danger setpoints for
the channel. For channels configured for thrust monitoring, these
words specify the over direction Alert and Danger setpoints.

4.2.3 Voltage of Probe at Zero Thrust Position (Zero Voltage)

THRUST PROBE ZERO GAP is the gap of the thrust probe when the monitored
surface is in the zero position. Thrust values are given as a deviation from this
zero position. When installing the probe in the machine, set the rotor at its zero
position and then gap the probe as specified in table 4.2.

Application Alert
Failure to set thrust zero voltage within the limits specified in table 4.2
could result in loss of machine protection. Verify alarm functions if you
use values outside table 4.2.

Application Alert
All bits in the Block Transfer Writes which are not used should be set to
zero. Failure to set unused bits to zero could result in loss of monitoring.

CHANNEL ZERO VOLTAGE only applies to channels configured for thrust

monitoring. Channels configured for other monitor types will ignore the zero
voltage words. When the average input voltage of the transducer for the channel
is equal to the zero voltage, the monitor channel will indicate zero thrust position.
The zero voltage code consists of a 12-bit binary code ranging from 0 to 4095
that corresponds to a zero voltage ranging from 0.0 to -24.0 Vdc.

Calculate the zero voltage using the following equation:

Zero voltage code = Integer((Zero Voltage / -24.0) * 4095)
Example of calculating zero voltage code:
Zero voltage = -9.20 Vdc.
Zero voltage code = Integer((-9.20 / -24.0) * 4095) = 1570
Zero voltage code = binary 0110 0010 0010
Zero voltage code = hex 622

All bits in the Block Transfer Writes which are not used should be set to

EXTERNAL BARRIER adjusts the OK limits to compensate for the barriers

attenuation of the signal. To enable this option set the bit to one. The scale factor
must also be adjusted to compensate for this attenuation. See notice below in
TRANSDUCER SCALE FACTOR section.
TURN CHANNEL OFF disables the channel when this bit is set to one. A disabled
channel will respond as follows:

4-10
 Configuring the System
• The monitor OK LED will remain on if the other enabled channels in the
monitor are OK. If all channels in the monitor are turned off, the monitor
OK LED will remain on unless any channel fails self-test.
• All channel data values will be zero.
• Self-test failures will be reported.
• Channel OK, Alert and Danger alarms will be inactive.
PEAK TO PEAK LOW FREQUENCY RESPONSE controls the low frequency response
of the channel when configured for radial vibration monitoring. Setting this bit to
one extends the low frequency response to 60 cpm from the normal 240 cpm.
This slows the peak to peak charge and discharge times used in the system
micro-controller program causing the monitor to respond more slowly to
changing vibration levels.
TRANSDUCER SCALE FACTOR is binary coded in English engineering units (mV/mil).
The scale factor may be programmed to be up to ±20 % of the nominal value for
the selected transducer type to compensate for system variances. Scale factors
outside these limits will produce configuration errors.

Notice:
Using external barriers reduces the nominal scale factor of the channel
by 4 % for Proximitors and Accelerometers, 7.5 % for 47633 Velocity
Seismoprobes and 16.6 % for 9200 and CEC4-126 Velocity
Seismoprobes. Decreasing the nominal, programmed scale factor will
compensate for this reduction.

Set the scale factor code to the required value in English engineering units as
shown in Table 4.3.
Scale factors are dependent on the transducer type selected. Appendix F gives
the range of acceptable scale factors for each transducer type.

Application Alert
Failure to enable Timed OK/Channel Defeat could result in false alarms
caused by faulty transducer wiring.

Application Alert
On reciprocating machines monitored with velocity or Velomitor®
sensors a sudden mechanical impact can over-range the sensor output.
If the monitor is configured with Timed OK/Channel Defeat enabled and
the over-range signal exceeds the OK limits the monitor may not
annunciate an alarm. This may result in a missed alarm and temporary
loss of machine protection. On Reciprocating Machines monitored with
velocity or Velomitor® sensors disable Timed OK/Channel Defeat.

Notice:
1. The high pass filter must be enabled when a channel is configured

2. Integration is not permitted with 2201/03-03 monitors.

LOW PASS FILTER ENABLE is used with 2201/03-02 and 2201/03-03 monitors to enable
the low pass filter option. Filtering is available on channels 3 and 4 of the 2201/03-02
monitor and on all four channels of the 2201/03-03 monitor. The low pass filter must be
enabled when the monitor is used with velocity, Velomitor and Filtered Proximitor
transducer types. Filtering is not permitted on channels configured for thrust monitoring.
Set the Low Pass Filter Enable bit to one to enable low pass filtering.
LOW PASS FILTER FREQUENCY is determined by the 8-bit Low Pass Frequency code and
the Low Pass Frequency Range bit. The low pass corner frequency must be at least four
times the value of the high pass filter corner frequency. The following table describes the
limitations of the low pass filter frequency value for various transducer types.

Where f is the low pass corner frequency.

Application Alert
Due to physical limitations of the operational amplifiers in the filters,
there are constraints on the actual range of the digital input, N, which
can be used. At low values of N, the offsets in the filter circuit become
large enough to reduce the available signal range below the required
levels. This means that for both high and low pass filters the minimum
value of N is 3 (decimal). Failure to set N to a valid value could result in
loss of monitoring.

Examples of calculating the Low Pass Frequency code:

1. Low pass frequency = 1000 Hz
Low Pass Frequency Range bit = 1
Low Pass Frequency code (Integer) = 1000 / 86.287 = 12
2. Low Pass Frequency = 200 Hz

 Operating the System

5. Operating the System

When the system is powered up, it performs a power-up self-test to determine
what elements are present in the system and if they are in good working order.
On successful completion of the self-test, the system waits for a valid
configuration to be loaded. When the system receives a valid configuration, it
carries out a further self-test and calibration. This can take up to two minutes,
depending on the number and type of Four Channel Monitors installed.
Monitoring will not start until the self-test and calibration are successfully
completed.

5.1 Status Indicators on the System Monitor

The System Monitor has two green status indicators that display the operating
condition of the monitor.

On — Indicates that the System Monitor

has passed the internal self-test.
On — Indicates that the System Monitor and the PLC
are communicating correctly.

OFF — Indicates that the communication has failed

for one second.

Flashing — Indicates that block transfer is slower

than one second.

5.2 Status Indicators on the Four Channel Monitors

The Four Channel Monitors have two green status LED’s that indicate the
operating condition of the monitor. If any of the LED’s fail to come on or go off
during operation, a fault is indicated. The table on the following page shows the
condition and corrective action required.

5-1
2201 Monitoring System Operation Manual

 System Status

6. System Status
The 2201 system uses Block Transfer Reads (BTR) and Discrete I/O Data Transfer
to send data to the PLC. The system uses BTR’s to communicate detailed system
information and the faster Discrete Data Transfer to communicate common OK
and alarm bits.
This section describes the content of the words in the BTR that communicates
with 2201/03-XX Four Channel Monitors only. Appendix A of this manual lists the
full content and data format of the block transfer read for a system containing
2201/03-XX Four Channel Monitors.
The BTR’s used to communicate with a system containing 2201/06-01 Low Speed
Monitors are described in 2201 Monitoring System with 2201/06-01 Low Speed
Monitors manual, part number 131699-01.

6.1 Block Transfer Reads

Block Transfer Reads are used by the 2201 system to communicate all system
information to the PLC. This information includes current values, alarm status, OK
status, and error codes.
A BTR is a block of data that varies in length depending on the number and type
of monitors in the 2201 system. This table describes the BTR’s for typical 2201
systems.

* The BTR data will be formatted as per appendix A of the 2201

Monitoring System with 2201/06-01 Low Speed Monitors manual, part
number 131699-01.

For example a system containing 6 Four Channel Monitors uses a BTR that is 56
words long, and a system with only one Four Channel Monitor uses 11 words. A
system containing both Four Channel Monitors and Low Speed Monitors uses 2
BTR’s, BTR1 is 64 words long, BTR2 is 63 words long. Each word of data is 16 bits
long.

Notice:
If your system contains 2201/06-01 Low Speed Monitors you need to
refer to 2201 Monitoring System with 2201/06-01 Low Speed Monitors
manual, part number 131699-01 for information about the format of the
data in the BTR’s.

Application Alert
Failure to set the correct BTR length for the type of system you are using
could result in loss of monitoring. Use only a BTR length of 11 to 56, 63
or 64 words depending on the monitor types in your system.

SELF-TEST IN PROGRESS indicates that the monitor is performing self-test and

calibration. Self-test is performed following a full block transfer write. A self-test
clears all Alert & Danger alarms and causes all channels to go not OK regardless
of their status before self-test. A self-test is in progress when this bit is one.
SPI COMMUNICATIONS FAILURE indicates that serial communications within the
System Monitor has failed. This failure also causes all channels to go not OK. If
this error occurs, replace the System Monitor. SPI Communications failure has
occurred if this bit is set to one.

A/D ERROR indicates that the System Monitor Analog to Digital Converter has
failed. This error causes all channels to go not OK. If this error occurs, replace the
System Monitor. An analog to digital converter error has occurred if this bit is set
to one.

6-3
2201 Monitoring System Operation Manual
SYSTEM COMMUNICATIONS TIME-OUT FAILURE indicates that errors have
occurred in the Block Transfer Read. These errors could indicate that the PLC has
not sent a BTR within the last second or that hardware errors exist within the
System Monitor. This error will normally be caused by a slow or missing BTR from
the PLC and will normally be corrected with the PLC program. This error could be
ignored if slow transfer of data is not a serious system problem. If the PLC is
operating normally and the error persists, replace the System Monitor. System
Communications Time-Out failure has occurred when this bit is one.

RAM TEST FAILURE indicates a failure of the RAM read-write test. This failure
causes all channels to go not OK. Replace the System Monitor. A RAM test failure
has occurred if this bit is set to one.

ROM TEST FAILURE indicates a failure of the ROM check sum test. This failure
causes all channels to go not OK. Replace the System Monitor. The ROM test
failure has occurred if this bit is set to one.

PLC MISSED DATA FROM 2201 SYSTEM indicates that the PLC did not retrieve the
last BTR data before the System Monitor updated the BTR data. The System
Monitor will update the BTR data every 50 milliseconds. This error will normally be
caused by a slow or missing BTR from the PLC and will normally be corrected with
the PLC program. This error may not be a serious problem because the 2201
system will communicate alarm and OK status to the PLC by using discrete data
transfers (See Section 7). It is very unlikely that this error could be caused by
defective hardware. The PLC has missed data from the 2201 system when this bit
is one.

POWER-UP/SEND NEW CONFIGURATION indicates a request for a full system

configuration. This bit will be set to one at power-up prior to initial system
configuration. This bit will also be set to one if the current configuration data has
been corrupted. A full BTW will clear this bit (See Section 4) if no errors occur
during the block transfer. If a verifiable full BTW does not clear this bit, replace
the System Monitor. Power-up/send new configuration request is active when
this bit is one.

Any of the voltage node errors described on the previous page will cause all
channels of the Four Channel Monitor to go not OK, except for those with a '*' in
front of the voltage node. Those with a '**' in front of the voltage node will cause
2 or 4 channels to go not OK depending on the type of the Four Channel Monitor;
channels 3 & 4 of a 2201/03-02, and all channels of a 2201/03-03 are affected.

SERIAL PERIPHERAL INTERFACE (SPI) ERROR indicates that the communications

between the Four Channel Monitor and System Monitor have failed. If the SPI
communications bit for the System Monitor is zero (BTR Data Word 0, bit 9), verify
that the Four Channel Monitor has a piggyback board installed. If the Monitor has
a piggyback board then replace the Four Channel Monitor. If this bit is one,
inspect the backplane and System Monitor before replacing the Four Channel
Monitor. SPI errors have occurred if the bit is one. This error causes all channels
of the Four Channel Monitor to go not OK.

6.5 Channel Current Value, OK, Danger and Alert

CURRENT VALUE represents the magnitude of the measured parameter for the
channel as a percent of full-scale range. The value is specified as a seven bit
code ranging from 0 to 103 that represents a full-scale value ranging from 0 to
103 % of the current full-scale range. For example, a current value of 50 % of full-
scale range is equal to a Current Value code of integer 50 and is represented by
the binary code 0110010.

GAP VOLTAGE is represented by a 12-bit code ranging from 0 to 2400 that

corresponds to a gap voltage of 0.00 to -24.00 Vdc. Use this equation to calculate
the channel gap voltage:

Gap voltage = -(Gap Voltage code / 100), measured in Vdc.

7. System Discrete Alarm Data

The 2201 Monitoring System uses Discrete Data Transfer to quickly communicate
OK and alarm status to the PLC. The discrete data consists of up to two words in
the PLC Input Image Table, the location of the words in the Image Table also
depends on the physical position of the System Monitor in the rack. The number
of bits used in the Image Table depends on the PLC addressing mode.

PLC Addressing Mode Number of bits in the Image

Table
Bits Words
Single slot or half slot 27 2
Two slot 4 1

Notice:
The location of the word(s) containing the Discrete Data Transfer bits
will vary in the Input Image Table depending on the type of PLC
addressing mode selected and the position of the System Monitor in the
chassis. For further information, consult your Allen-Bradley PLC5
documentation.

These discrete data bits correspond to the 2201 Monitoring System OK and alarm

8. System Verification
Before you put your 2201 Monitoring system online, use the procedures in this
section to verify that all channels in the system are operating properly. To verify a
channel, first use Section 8.1 to test the OK Limits and then use one of the
calibration procedures (Sections 8.2 through 8.5) to calibrate the channel. Use the
following table to determine which calibration procedure to use:

Channel Type Calibration Procedure

Thrust Position Proximity Transducer. 8.3 8-4

Velocity and Velomitor Transducer. 8.4 8-6

Acceleration Transducer. 8.5 8-10

Application Alert
Tests will exceed alarm setpoint levels, causing alarms to activate.

Notice:
2201/06-01 Low Speed Monitors provide other types of monitoring. If
your system contains 2201/06 Low Speed Monitors, system verification
tests may differ from the procedures in this manual. Refer to manual
131699-01 for information about the 2201/06 monitors.

8.1 Test OK Limits

1. Disconnect the transducer wiring from the signal input terminals of all four
channels 1 to 4 on the front of the 2201/03-XX monitor.

8-1
2201 Monitoring System Operation Manual

2. Connect the power supply to SIG and COM of the channel 1 terminals, noting
the polarity, as shown in the diagram on the following page.

Notice:
Make sure all jumpers on 2201/03-02 and -03 Four Channel Monitors are
set correctly and a valid configuration is downloaded.

3. On the remaining three channels, connect resistors of the values shown in the
following table, between PWR and SIG of the signal input terminals.

4. Apply a dc voltage within the range specified by the transducer OK limits in

Appendix E for the type of vibration transducer being used. Check that the
Monitor OK LED comes on. If the Timed OK/Channel Defeat option is selected,
there will be a delay of 30 seconds.

5. Slowly increase the input voltage until the Monitor OK LED goes off. Verify that
the voltage corresponds to the upper transducer OK limit for the transducer type.
Decrease the voltage slightly and wait until the Monitor OK LED comes back on.
Slowly decrease the voltage until the Monitor OK LED goes out. Verify that the
voltage corresponds to the lower transducer OK limit.

8-3
2201 Monitoring System Operation Manual
6. Return the dc voltage to a mid-value between the transducer OK limits and
wait for the Monitor OK LED to come on.

7. Repeat this procedure for all channels on all

2201/03-XX Four Channel Monitors installed in the
rack. Remember to check the correct transducer
OK limits for the type of transducer system
installed, and to connect OK resistors to the other
three channels to make the monitor go OK.

8. Re-connect the transducer wiring of all probes

to the signal input terminals of the Four Channel
Monitors.

8.2 Channel Calibration for

Vibration and Filtered Vibration Proximity Transducer
Options
1. Disconnect the transducer wiring from the signal input terminals of the
channel being calibrated from the front of the 2201/03-XX monitor.

2. Connect the power supply and function generator to the SIG and COM
terminals of the channel being calibrated as shown in the following diagram.

8-4
 System Verification
3. Adjust the dc power supply to a mid-value between the transducer OK limits as
specified in Appendix E. Set the function generator output to a 1 kHz sine wave
and adjust the amplitude so that the channel reads full-scale. For filtered
vibration proximity transducers, choose a frequency within the band-pass region
of the filter configuration. Use table 8.1 to verify that the simulated ac vibration
amplitude corresponds to the Current Value reading in the block transfer read.

Notice:
When you use filtered vibration proximity probes, be sure that the
function generator signal frequency is within the band-pass region of
the filter configuration.

Example: For a 7200 5mm transducer without barriers and configured for 5 mils
full-scale range, table 8.1 shows a conversion factor of 1 mil = 200 mV pp.
Therefore the full-scale peak to peak input voltage amplitude will be 5 × 200 mV
pp = 1 V pp.

3. Set the zero voltage in the block transfer write for channel A to -8.00 Vdc and
initiate a self-test.

Application Alert
This procedure may require you to alter your monitor configuration.
Remember to return configuration back to normal after completing test.

4. After the self-test has completed, set the power supply to -8.00 Vdc and verify
that the monitor display reads 0 mils (0 mm).

5. Set the power supply voltage so that the channel reads positive full-scale.
Refer to table 8.2 to calculate the correct dc input and verify that it corresponds
to the power supply reading.

 System Verification

Notice:
If the normal direction is toward the probe, then the full-scale value is
the zero voltage minus the full-scale voltage. If the normal direction is
away from the probe, then the full-scale value is the zero voltage plus
the full-scale voltage.

Example: For a 3300 8mm transducer without barriers and configured for 40-0-
40 mils full-scale range, table 8.2 shows a conversion factor of 1 mil = 200 mV.
Therefore the full-scale dc input voltage change will be 40 × 200 mV = 8.00 Vdc. If
the normal direction is toward the probe with a zero voltage of -8.00 Vdc, then the
full-scale value will be: -8.00 Vdc- (-8.00 Vdc) = 0.00 Vdc. If the normal direction is
away from the probe with a zero voltage of -8.00 Vdc, then the full-scale value will
be: -8.00 Vdc + (-8.00 Vdc) = -16.00 Vdc.

6. Set the power supply voltage so that the channel reads negative full-scale and
verify that the calculated value corresponds to the new power supply reading.

7. Repeat this procedure for all channels configured to use thrust proximity

2. Connect the function generator, capacitor, and resistor to the PWR, SIG and
COM terminals of the channel to be calibrated as shown in the following diagram.

3. Set the function generator output to a 100 Hz sine wave with 0 Vdc offset and
adjust the amplitude so that the channel reads full-scale. Use table 8.3 to verify
that the simulated ac velocity amplitude signal corresponds to the Current Value
reading in the block transfer read.

 System Verification

3. Adjust the dc power supply to a mid-value between the transducer OK limits as

specified in Appendix E. Set the function generator output to a 100 Hz sine wave
and adjust the amplitude so that the channel reads full-scale. Use table 8.5 to
verify that the simulated ac acceleration amplitude signal corresponds to the
Current Value reading in the block transfer read.

Notice:
When you use acceleration transducer systems, check that the function
generator signal frequency is within the band-pass region of the filter
configuration. Section 4 shows how to change the filter corner

Application Alert
This procedure may require you to alter your filter configuration.
Remember to return configuration back to normal after completing the
test.

Example: For an acceleration transducer (25 mV/g Interface Module) without

barriers and configured for 2 g full-scale range, table 8.5 shows a conversion
factor of 1 g pk = 50 mV pp. Therefore the full-scale peak to peak input voltage
amplitude will be 100 mV pp. Note: A multimeter will read an ac voltage as an
rms voltage, Vrms, where: Vrms = (0.707/2) × (V pp), for a sine wave input. Hence,
if a full-scale signal of 100 mV pp is applied, the multimeter will read: Vrms =
