Revision 1.0 Apr 12, 2021
SECTION 1: Introduction and General Information
1-1 Equipment Description
1-1.1 Purpose
The PBS-4100+ Portable Balancing System (see Figure 1-1) is used to perform trim balance and
vibration diagnostics on all types of gas turbine engines and rotating machinery. It has been
designed as a rugged, portable instrument for use on the flight line, in engine test cells, in
power plants and on the factory floor.
A key reason for using the PBS-4100+ system is to reduce the amount of time required to
perform vibration analysis and trim balancing of gas turbine engines and rotating machinery.
This in turn improves engine/machinery quality, saves engine running time, fuel, labor, and
improves overall equipment availability rates.
When combined with MTI’s WinPBS software, the PBS-4100+ saves time by incorporating
features such as automatic data collection, stored engine parameters, and a Balancing Wizard
that guides users through the balancing process. Balancing can be done using stored influence
coefficients for "one-shot" balancing that automatically calculates specific balance solutions,
complete with manufacturers’ part numbers for balance weights and specific instructions about
balance weight mounting locations.
Another advantage of the complete PBS-4100+ package is that it gives the user a set of “tools”
to perform vibration diagnostics. These tools can be used to determine whether trim balancing
is appropriate and to identify potential engine mechanical problems.
1-1.2 Basic Functional Description
The PBS-4100+, when combined with the MTI WinPBS software, is a complete engine vibration
analysis and balancing system. It has been designed for use on the flight line and in engine
test cells, and the system contains a number of features to make the task of engine vibration
testing as fast and easy as possible. With the PBS-4100+ system users are able to:
Perform vibration surveys of engine accelerations and decelerations. During
each run, vibration data from all channels are acquired and displayed.
Monitor overall and synchronous components. During all engine runs,
users can easily monitor total vibration levels, and important vibration
components to aid in diagnosing vibration-related problems.
Acquire vibration signal spectrum data. Using this data, users can pinpoint
the sources of vibrations within the engine for a fast and accurate diagnosis.
Trim balance engines. The WinPBS software’s
Balancing Wizard
guides
users through the process of balancing engines using trial weight or stored
influence coefficient methods.

Store valuable engine data. All of the data that the PBS-4100+ system takes
can be stored for printing and review in the future. All stored data can be easily
sorted, displayed and printed.
To start testing an engine, the operator must first select the specific engine type from a list
displayed on the computer screen of the PBS-4100+ laptop running the WinPBS software, or by
selecting the specific engine file on the DAU’s touchscreen display. The operator's selection
directs the PBS-4100+ system to take engine specific data from the "parameters file" to control
how the PBS-4100+ takes engine data and displays it for the user. The parameter files and the
PBS-4100+ software are stored on the hard disk of the PBS-4100+ system computer.
After the engine has been selected, and the monitoring software has started, the PBS-4100+
continually collects speed and vibration data from the engine under test. This data can be
displayed in graphical or tabular form. When vibration levels demand balancing, the PBS-
4100+’s companion WinPBS software’s
Balancing Wizard
guides the collection of engine
data, and calculates a balance solution. Balancing solutions are graphically displayed to show
the specific balance plane holes in which weights should be installed to reduce engine
vibrations. Balance solutions also include the size and part number of weights to be installed.
A record of each balance run is automatically stored and can be printed to provide a historical
record when desired.

Revision 1.0 Apr 12, 2021
The PBS-4100+ has been designed to operate using either aircraft power or a ground power
source. Input power control circuits feature an autosensing/autoswitching function, which
avoids the risk of equipment damage due to improper power selection. Input power can be
either 115 or 230 VAC (+/- 10%) and 50, 60, or 400 Hz (+/- 10%).
The PBS-4100+ uses input data signals that are generated by one or more vibration pickups
mounted on the engine. Some engines have built-in vibration pickups, whereas other engines
require the installation of temporary pickups for ground test. The PBS-4100+ also requires an
engine speed signal for balancing tasks done through the WinPBS software. This can come from
a built-in speed pickup (when present) or from a ground test tachometer.
Specially designed cable sets are used to connect the PBS-4100+ to the appropriate vibration
and speed pickups on a particular engine type. Examples of ways in which the cable set are
designed to connect to pickups include:
Engines mounted on aircraft
Connect direct to pickups mounted on the engine
Connect to pickups via engine wiring
Connect to pickups via aircraft vibration monitoring (AVM) system
Engines mounted in a test cell
Connect directly to pickups mounted on the engine
Connect to pickups via test cell wiring
These specially designed cable sets are available for almost all commercial engine/aircraft
combinations. Contact your MTI representative for details concerning your specific needs and
applications.
1-1.3 Hardware Description
The PBS-4100+ system is comprised of a Data Acquisition Unit (DAU) and a portable computer
with the
PBS for Windows
(WinPBS) software installed. The computer is typically a “laptop
style portable computer, although other configurations are available.
Major components of the PBS-4100+ are illustrated in Figure 1-1 and listed Table 1-1. Further
description of the major components is provided in paragraphs 1-1.3.1 through 1-1.3.8.

Revision 1.0 Apr 12, 2021
For each PBS-4100+ system, the computer and the DAU are a matched set. Although a specific
individual computer may work with more than one DAU, and vice versa, MTI does not represent
that this will generally be true. Problems are especially likely to occur if a computer is
substituted for a computer of a different brand and if incompatible software versions exist on
the DAU and the computer. Each computer and its associated DAU are assembled, inspected
and calibrated as a single system at the factory.
Accessory items such as signal conditioners, adapters, cables, etc., are available to assist in
interfacing with the engine under test. Accessory items are described in paragraph 1-1.4.
Some variations in equipment supplied may occur due to the use of alternate vendor items.
1-1.3.1 Portable Computer
Illustrated in Figure 1-1, item 1, the computer is a commercial off-the-shelf laptop unit
(variations are possible, depending on customer requirements). Specifications vary depending
upon options selected by the customer, but the typical computer configuration is described as
follows:
CPU: Modern Intel Core Processor
RAM: 4 Gigabytes minimum
Disks: SSD 128 Gigabytes minimum
CD-R/W Drive
Ports: 10/100/1000 Ethernet LAN
Wireless LAN (802.11a/b/g/n)
USB Ports
Operating System: Windows 10 Professional (64-bit English)
Each system also includes an AC power adapter, plus a nylon carrying case is included with
each portable computer for protection and carrying convenience.
1-1.3.2 Data Acquisition Unit
Illustrated in Figure 1-1, item 6, the DAU contains the electronic circuitry that receives and
processes signals generated by the engine speed transducers and vibration pickups. After
converting these signals, the DAU transmits the resulting data to the portable computer. The
standard DAU provides two tachometer input channels and four vibration channels. The PBS-
4100+ DAU also features a full color touch panel that displays current engine speeds, and can
also be used to display vibration data, system settings and system diagnostic procedures.
AC power is supplied to the DAU via a built-in power cord (Figure 1-1 item 5). Inside the DAU,
the AC power is distributed to the internal DC power supply. The internal power supply satisfies
the DC power requirements of the DAU, plus the 12 volt DC power required for accessories such
as external charge amplifiers.
A cushioned nylon carrying case is included with each DAU. These cases have been designed
to provide easy means of carrying the DAU and to protect it during shipment. However, prior to
operation, the DAU must be removed from the carrying case to ensure that adequate cooling is
provided for the internal circuitry of the DAU.

1-1.4 Data Acquisition Accessories
The items shown in Figure 1-2 and Figure 1-3 illustrate some of the system accessories that are
available to complement your PBS-4100+. These items are briefly described in paragraph 1-
1.4.1 and 1-1.4.2. For additional information about the full line of PBS accessories, contact MTI
Instruments, Inc.
1-1.4.1 Charge Amplifier
Illustrated in Figure 1-2, the charge amplifier converts charge-mode signals from engine
accelerometers to voltage-mode signals. Depicted is a 2-channel unit, which can convert the
signals from two accelerometers simultaneously. Four (4) channel units are also available in a
similar style product. Conversion of accelerometer signals to voltage-mode provides greater
immunity to noise and allows signals to be reliably transmitted over greater distances. The
charge amplifier is normally installed at the engine. It is not needed if another charge amplifier
is already present (as part of test cell equipment) or where velocity probes are used instead of
accelerometers.
Figure 1-2: 41CA Two Channel Charge Amplifier
1-1.4.2 Interface Cables
The PBS-4100+ cabling system has been carefully designed to minimize our customers
investment in cables yet provide them with maximum flexibility. More than 100 different cables
have been designed to accommodate most commercial and military aircraft/engine
configurations. Figure 1-3 illustrates three very common and essential cables; two different
engine interface cables, and a PBS jumper cable.
An engine interface cable (EIC), with appropriate jumpers at each end, carries signals from the
engine directly to the PBS-4100+. It contains four pairs of twisted-pair conductors, with
shielding on each pair. One of these pairs is normally reserved to provide 12V DC power to
