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.

Revision 1.0 – Apr 12, 2021

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
