the exact differences between the three models, see Section 2.3
“System Specifications”.

2.2.1 Vibrex 2000 System Overview

The Vibrex 2000 unit is a hand-held, battery-powered vibration
analyzer. It is a vibration analysis and balancing tool that rapidly
and accurately acquires and analyzes aircraft vibration data. It
uses that data to calculate balance solutions and to analyze
aircraft vibration levels across a broad frequency range.

The Vibrex 2000 system provides accurate helicopter vibration
readings for chart calculations on main and tail rotors, shafts, and
blowers. As a spectrum analyzer, they provide the operator with
an overview of rotor and drive-train vibration. The Vibrex unit
uses cables and transducers (for example, the Honeywell Model
7310 Velocimeter, magnetic pickups, and photocells) from
previous generations of our equipment, further reducing the cost
of ownership.

2.2.1.1

System Operations

The Vibrex 2000, Vibrex 2000 Plus and Enhanced Vibrex 2000
Plus systems allow the user to do the following operations:

Propeller Balance Operations - Easy-to-understand menus let
the user initiate up to four different balancing jobs at one time.
The instrument can automatically correct for the propeller
response to weight changes, and the user can save this correction
for future balancing operations.

A “first round hit” solution means lower vibration solutions,

even on the first move. Two channels allow the user to measure
the propeller and rear of the engine during balancing. All
measurements, solutions, sensitivities, and annotation are saved

13841 Rev A

in memory and can be reviewed on the instrument, printed out on
the optional portable thermal printer, or downloaded to a
personal computer (PC) through a standard RS-232 serial cable.

Rotor Track-and-balance Operations - The track-and-balance
menus are designed to simplify taking multiple measurements
without having to change the setup. The user can acquire and
save balance readings, in inches per second (IPS) and clock
angles.

The user can also track up to seven helicopter blades, using the
Honeywell Model 135M-12 Strobex Tracker.

Spectrum Analysis - Vibration peaks listed by frequency or
order are available up to 24,000 RPM (600,000 for V2K+). The
lists are based on 400-line fast Fourier transform (FFT)
calculations. As with all measurements, the lists can be saved,
reviewed, printed, or transferred to a PC.

The user can save the complete spectrum and view it with a
standard spreadsheet or with one of Honeywell's ground-based
software packages. Up to twelve orders and associated half­orders can be listed.

2.2.1.2

System Benefits

The Vibrex 2000 systems offer the user the following benefits:

 Reduced aircraft operating costs and down time
 Reduced propeller and rotor vibration that translates into

increased reliability, increased mean time before failure
(MTBF) for avionics, as well as mechanical and
aerodynamic structures

 Better ride comfort for pilots and passengers

13841 Rev A

 Federal Aviation Association (FAA)-approved propeller

balance, when used with Honeywell’s The Smooth Propeller
manual publication

 Balance jobs that are stored in memory and can be archived

on a PC

 A 32-bit microprocessor for rapid-balance computations and

FFT calculations

 Use of common rechargeable or disposable D-cell batteries
 Honeywell's worldwide customer support

2.2.1.3

Self-Test Feature

Each time the Vibrex 2000, Vibrex 2000 Plus or the Enhanced
Vibrex 2000 Plus unit is powered up, it checks its memory and
characterizes its analog filters to compensate for aging
components, temperature drifts, and so on. The unit then reports
the total amount of time the batteries have been used since
installation.

Press the unit’s STATUS key to display checked battery and
sensor voltages, along with the date, time, and firmware version.
Using this key, you may print the fault log for easy
troubleshooting. See Section 6.4.1 “Fault Logs” for details.

Self-Test Modes - The power-up self test has the following

modes:
Comprehensive Test - Performed if the unit has been turned off

for more than 2 hours and takes approximately 20 seconds, that

is, the unit’s full built- in test (BIT). Such timing allows this test

to be done sufficiently to ensure that all the unit’s functions are

tested at reasonable intervals.
Abbreviated Test - Takes only a few seconds. The unit does this

test if it has been in use during the last 2 hours. The
comprehensive test (or BIT) is unnecessary each time the unit is

13841 Rev A

powered up, so the unit only does an abbreviated test for short­term power-down/power-up cycles.

2.2.2 Vibrex 2000 Plus

Enhancements

The Vibrex 2000 Plus model represents a significant
performance increase over the Vibrex 2000 (Part Number 13590­2 and earlier). In addition to all existing Vibrex 2000 benefits
features, and capabilities, the Vibrex 2000 Plus system offers the
following extended capabilities.

 An increase in maximum spectrum frequency from 24,000

RPM to 600,000 RPM (10 kHz)

 A graphic spectrum viewing mode
 An extended balance frequency range from 120 RPM to

30,000 RPM

 Support for running up to four propeller balance jobs in

parallel operation (can suspend one then jump out and start
another)

 Four times the memory, allowing more data to be saved (1

Mb)

 The ability to store balance jobs, adjustments, sensitivities,

spectra, and balance measurements in the instrument’s

memory and archive them on a PC

 Storage of firmware in the instrument’s Flash memory,

facilitating software upgrades and enhancements; there is no
longer any need to open the instrument for this purpose

2.2.3 Enhanced Vibrex 2000 Plus

Enhancements

Using the same hardware package as the Vibrex 2000 Plus, the
Enhanced Vibrex 2000 Plus model improves some of the Vibrex
2000 Plus software features as well as adding a completely new
capability to track and balance specific helicopter (version

4.xx+) and fixed-wing aircraft (version 5.xx+) models. These
features are summarized below.

 Adds the ability to save and recall Propeller Balance

configurations. Auto-corrected and user-entered balance
coefficients can be renamed and saved for later use.

 The FasTrak optical blade tracker is now supported in

addition to the Strobex. The EV2K+ provides the ability
to use preset helicopter FasTrak setups as well as modify
and create new FasTrak configurations.

 Adds an extensive new Helicopter Balance capability

(version 4.xx+). A complete set of balance charts for 28
helicopter models and variants are included. These
function as simple “single-plane” balance charts and can
be selected for various components, flight regimes,
change types and measurements. These balance charts
are the same as provided in the advanced VXP balancer.
They can be modified and stored as new configurations.

 Adds an extensive new Fixed Wing Balance capability

(version 5.xx+) similar to the EV2K+ Helicopter

3.2.1 Display

The Vibrex 2000 and Vibrex 2000 Plus use an LCD screen on
the front panel, for visual output. This screen subdivides into
eight lines of text.

CAUTION: In extreme temperatures, the display may turn
black (too hot), or blank (too cold). In hot climates, covering
the display from direct sunlight is generally sufficient to
prevent the screen from becoming unreadable. In cold weather
climates, it is advisable to keep the Vibrex unit in a warm
enough place (near or above freezing if possible) to ensure its
continued use.

3.2.1.1

Adjusting Screen Contrast

With the Vibrex unit powered up, use the raised buttons on the
arrowheads to the right of the display to adjust screen contrast
for easy viewing.

The display’s contrast changes with changes in temperature. As

the unit warms, the screen stabilizes at a darker setting than
viewed when powered up initially. Small corrections, using the
arrowhead buttons, restore the screen to a comfortable viewing
contrast. The user may use the contrast keys at any time.

3.2.1.2

Screen Operations

The Vibrex unit’s display has the following operational

characteristics:

13841 Rev A

 Plain brackets ([ ]) display to indicate choices for alpha or

numeric (alpha-numeric) entries. The user may edit the
information between the brackets.

 Generally, a cursor blinks inside the brackets, indicating the

space is ready for the appropriate type of data entry.

 Angle brackets (< >) indicate that the user has

preprogrammed choices. Press the adjacent context key to
cycle through the available choices.

 Up (^) or down (v) arrows on the left margin indicate there is

more information that can be displayed, than the eight lines
shown. Press the context key next to the arrowhead to see

3.3 Printing Data

The Vibrex 2000 and Vibrex 2000 Plus allow the user to print
hard-copy readouts of collected data or status information. The
systems print through an RS-232 serial port on the connector
subpanel. Because of the large selection of serial printers, it is
impossible to address every setup for every printer. For details,
refer to any appropriate PC and/or printer manual that pertains to
the user’s computer system.

3.3.1 Direct Serial Printing

To connect the Vibrex unit to a Seiko Model DPU-414 printer,
connect the nine-pin DBA female cable that terminates against a
9- to 25-pin male adapter. Use an adapter that has the No. 5 pin
of the 9-pin connector switched to the No. 7 pin of the 25-pin
connector.

This switching can occur on the adapter or in the 9- to 9-pin
cable or in the 9- to 25-pin connector. This type of setup works
for most other serial printers as well.

3.3.3 Reading FFT Data

One of the types of data available to print in the Vibrex 2000 or
Vibrex 2000 Plus spectral data file is called raw FFT. Fast
Fourier transform (FFT) is a method used to record vibration
spectra digitally. An FFT consists of individual bins (also called

13841 Rev A

44

Chapter 3 – Getting Started

Honeywell Confidential: Use or disclosure of information on this page is subject to the restrictions on the title page.

lines). Each bin contains a percentage of the RPM range. The
user may determine the actual RPM range contained in each bin
by dividing the spectrum range (in RPM) by the number of bins.

The Vibrex unit uses a 400-bin FFT setup. If the frequency range
selected is 0 to 24,000 RPM, each bin consists of 60 RPM worth
of vibration energy. As the RPM range goes down, the bins hold
fewer RPM, so the RPM accuracy is generally improved for the
spectrum. When the user prints raw FFT data, both the header
information containing the annotation, channels numbers, RPM
range, day/date code, and so on are recorded with the vibration
energy in each bin.

The number in each line of the FFT as printed in the Terminal or
Hyperterminal program is equal to the inches per second (IPS)
divided by 1000. For example, if the range selected was 24,000
RPM, the 9th bin (9th numerical entry after the 0, would
correspond to 540 RPM in the spectra and the 200th bin (line)
would correspond to 12,000 RPM.

The value in storing the vibration measurements as FFT data lies
in its PC versatility. The user can create plots and graphs of the
data, using the Honeywell V2K Plot Software program. For
details on how to use this program to plot FFT data, see the V2K
Plot Software User Guide.

3.3.4 Using the PRINT Key

Only data that has been stored to history and the operating Status
screen may be printed. The two methods of finding desired
information to be printed are

 Global printing from the PRINT key
 Printing with the REVIEW and PRINT keys

This section explains these printing modes.

4.4.1 Velocimeters

In general, the user may use guidelines given in The Smooth
Propeller to determine correct Velocimeter placement with the
Vibrex 2000 or Vibrex 2000 Plus system. In addition, the user
may use the following general guidelines for making sure the
Velocimeters are in the correct locations:

 Mount the balance Velocimeter as near to the plane of

rotation of the propeller as practically possible.

 The check Velocimeter is mounted at the rear of the engine.

A rear Velocimeter is mounted when the mass of the crank
shaft and propeller extend across some longitudinal distance,
such as are found in most direct-drive reciprocating engines.

 It is not necessary to mount a check Velocimeter on geared

engines or radial engines. The purpose of the check
Velocimeter is to ensure the imbalance comes from
differences in the mass of the propeller and not the crank
shaft. Failure to monitor the rear of the engine and
attempting to balance may deteriorate the apparent vibration
rather than decrease it, even though the level at the front of
the engine goes down.

 Normally, for a direct-drive engine, the front and rear of the

engine provide measurements of similar amounts of
imbalance, but at opposite clock angles (if both Velocimeters
point the same direction). As the front of the engine becomes
displaced upward by the imbalance the rear of the engine
shows a downward displacement, and so on.

 When an imbalance happens solely because of propeller

mass differences, as the front inches-per-second (IPS)
vibration level goes down, the rear IPS also becomes
reduced to acceptable levels.

 If the balance IPS level goes down and the rear IPS remains

the same or is reduced, the effect of balancing is still correct
for the engine. If the balance IPS level goes down but the

13841 Rev A

73

Chapter 4 - Installation

Honeywell Confidential: Use or disclosure of information on this page is subject to the restrictions on the title page.

rear IPS increases, the propeller does not need to be
balanced. The cause of the imbalance is probably the crank
shaft or an asymmetric aerodynamic loading on the
propeller.

 The user can check for an symmetric loading on the

propeller by dynamically tracking the propeller with the
Strobex. If the user can discount the propeller as a source of
any vibration, the only way to correct the problem is to
examine the crank shaft.

 There are several commonly used locations on flat opposed

engines.

 Because of differences in cowling, baffling, and accessory

sections, make sure that the transducer is mounted in such a
way that the engine can get enough air for cooling during its
run-up.

Velocimeter Brackets - Generally the brackets supplied in the

application kits are adequate for general use.

4.4.2 Photocell System

The operational end of the Vibrex 2000 or Vibrex 2000 Plus
photocell system is the Banner photocell probe (from now on
called the photocell). This unit is self-contained and uses a
visible red light (650 nm) from a light-emitting diode (LED)
triggered by a retro-reflective target. This light reflection sends a
one-per-revolution pulse to the Vibrex unit for frequency-and­balance phase measurement.

Photocell Range - The effective range of the photocell is 3 in.

to approximately 7 ft. For the best results, place the photocell
approximately 2 ft from its companion retro-reflective target.

13841 Rev A

74

Chapter 4 – Installation

Honeywell Confidential: Use or disclosure of information on this page is subject to the restrictions on the title page.

Getting Started - The photocell receives power from the

Vibrex unit. Turn on the Vibrex unit and press the following
keys (in this sequence):

PROPELLER BALANCE, START, START

These key strokes activate the photocell system. Make sure to
activate the system before placing the retro-reflective target on
the rotating object.

4.4.2.1

Retro-Reflective Target

Keep the following important characteristics of target reflection
in mind, when using the photocell:

 Honeywell recommends using the retro-reflective target

supplied in the kit, with the photocell. This retro-reflective
target is unique because it reflects light back to its
illuminating source. On close examination, the target
consists of thousands of small glass beads or prisms held on
an adhesive backing held in place on the rotating component
with adhesive.

 The Honeywell targets are only retro-reflective if the glass

beads are left exposed. Coating the glass beads with any
clear sealer destroys the retro-reflective quality of the target.

 The user can use corner-cube retro-reflective tape. The user

can identify this type of tape by a chain-link pattern on the
surface, and a glossy surface finish.

 The use of reflective tapes is not recommended. Reflective

tapes have very narrow return angles and must be mounted
in such a way that allows the background reflection to
adversely affect the gain of the photocell.

 Other retro-reflective tapes are similarly not recommended

unless they are the same material as the Honeywell retro­reflective targets.

13841 Rev A

75

Chapter 4 - Installation

Honeywell Confidential: Use or disclosure of information on this page is subject to the restrictions on the title page.

 The glass bead density (which determines the percent of

retro- reflectiveness) of garden variety retro-reflective tapes
(such as that found on highway cones or survival jackets) is
less than 50 percent of our target in most cases. In most
cases these tapes are inadequate as retro-reflective targets for
the photocell.

The correct size of the retro-reflective target depends on the
distance between the photocell and the reflective target, as well
as the speed of the retro-reflective target as it passes through the
photocell beam.

The orientation of the photocell can also vary, depending on the
size of the target. A single strip of the Honeywell retro-reflective
target, aligned so it dwells in the photocell beam for the longest
period of time, is usually adequate. For details, see the the
information in Section 4.4.2.4 Photocell Placement.

4.4.2.2

General Photocell Use

The photocell triggers, that is it sends the timing pulse to the
balancer, as the target leaves the photocell beam. This being the
case, if the user wants to do really accurate alignment of the
target in the beam between adjustments, simply pull the target
through the photocell beam until the alignment light on the back
side of the photocell just goes out, then stop.

Using an erasable marker, make two marks next to each other,
one on the spinner and one on the cowl. It doesn't matter where.
One can then always align these marks and know the photocell
beam is aligned with the target on every adjustment. Over the
long haul, this accuracy will save quite a bit of time, and
eliminate errors in target placement.

Not Used

Most of the targets are rectangular. Most of the installations for
the photocell result in a beam that hits the propeller in an arc. It

is possible that the beam might “cut” the target at something less

than its length. This is truer of placements close to the center of
rotation than farther away. Keep in mind the pitch of the
propeller can change too, causing loss of signal on the target.

4.4.2.3

Repair of Photocell Wiring.

The photocell is used in the sourcing mode. The wire color codes
are shown in the table below.

4.4.2.4

Photocell Placement

When mounting the photocell system, the user must take care in
positioning the photocell probe. The two lenses of the photocell
probe work best when

 They are tangent to the arc created by the retro-reflective

target (see Section 4.4.2.4 Photocell Placement).

 The retro-reflective target is aligned tangent to the arc

created by the radius where it is attached.

13841 Rev A

Chapter 4 - Installation

Photocell Procedures - Locate a specific placement for the

photocell probe, as follows:

1. Rotate the component to be balanced to a position where a

blade or some easily identifiable part of the rotating
assembly crosses the photocell beam.

2. Place a retro-reflective target on the rotating component

where it can be illuminated by the photocell beam. Make
sure to align the target strip tangentially relative to the
component’s circular motion.

NOTE: The user can locate correct placement of the target
by checking the small LED, pulsating on the back of the
photocell probe. This LED is the alignment indicator. As
the LED pulses faster (at a higher rate), it indicates better
alignment. However, if the pulse rate is too fast to observe,
the user must reduce the size of the target.

3. Mount the photocell probe in an optimum position, using the

photocell bracket (see the example diagram below).

In most cases, the user can collocate the probe with the
Velocimeter, but for some installations, the user may
need to mount the probe by itself, using the single
mounting screw provision.

NOTE: The user may need to experiment with several
mounting techniques and/or positions to find the
optimum positioning.

Incident Light - Unwanted light that reflects into the photocell

probe could result in incorrect measurements. This type of light

is called incident light, that is, light hitting the assembly when
the target is not in line with the beam. For example, light
reflected from a shiny surface that enters the photocell probe is
incident light.

For the best results, mount the photocell probe so any incident

light is reflected away from the photocell’s beam (see the

diagram below). This position is especially necessary when the
target attaches to bright metal or glossy surfaces.

The illustration below shows an example of correct photocell
positioning for optimum retro-reflection.

4.4.2.5

Target Positioning

Rotate the component to be balanced to a position where a blade
or some easily identifiable part of the rotating assembly crosses
the photocell beam. Place a single retro-reflective target strip
aligned tangentially on the rotating component, where the target
is illuminated by the photocell’s beam.

Target Diagram - For details on this operation, see below.

Check the small LED pulsating on the back of the photocell to
verify correct placement. A faster pulse rate of the alignment
indicator means better alignment. However, if the pulse rate is
too fast to observe, the user may need to reduce the length of the
retro-reflective target strip.

To calculate the best dwell time and length for the retro­reflective target in the photocell beam, see the graph that shows
minimum target length, under “Appendix A: Photocell Taping”.

4.4.3 Magnetic Pickup

If the user needs instructions on magnetic pickup installation,
refer to the aircraft maintenance manual for the subject aircraft.
Refer to the appropriate Honeywell Model 177M-6A Vibrex
checklist for magnetic pickup installation, if other documentation
is inadequate. The installation for the Vibrex 2000 and Vibrex
2000 Plus is the same.

Chapter 4 - Installation

Honeywell Confidential: Use or disclosure of information on this page is subject to the restrictions on the title page.

NOTE: Generally, for helicopter main rotor
installations, the user may install a magnetic pickup
assembly to provide the Vibrex unit with a necessary
azimuth signal. This signal provides a baseline for
taking vibration measurements, in the same way as the
photocell system does for propeller balance operations.
Note that the Vibrex unit uses only a single interrupter.

If the user does not have an applicable Vibrex unit checklist and
require one, contact Customer Support and order it (see Section

1.2 “Product Support”).

Photocell Mounting - The photocell’s distance from (gap

between) the target (interrupter) is anywhere from 7 in. to 7 ft.
What they do not say is the size target required to use it at 7 ft. In
most aviation applications the target tape would have to be so
big you couldn't find anywhere to put it, and it would throw the
item out of balance a good amount.

Photocell Tape Width - Try to stay in a range of between 5

in. to 18 in. Also, since the photocell requires the target to be in
the beam for a specific time period, try to stay at a small radius.
A target tape placed on the back of the spinner at the 6-in. radius
might be 0.5 in. long (width of tape passing through the beam)
for an RPM of 2400. The same target to provide the same dwell
(length of time) in the beam at the 30-in. station would have to
be approximately 2 in. long.

For details on calculating photocell tape length, see “Appendix
A: Photocell Taping”.

This section gives a brief explanation of several Vibrex 2000 and
Vibrex 2000 Plus installations on selected aircraft and some
general types of aircraft. Use these summaries as guidelines for
the user’s own installation operations.

4.5.1 Lycoming O/IO-320/360

There is a 1/4-20 threaded boss on the forward left-hand side of
the engine crank case, which is ideal for mounting. Often the
Velocimeter can be mounted without removing any cowling. The
photocell can be collocated with the Velocimeter on many
installations.

Alternately, the forward-most backbone case half bolt may be
used to mount the Velocimeter. In both installations, orient the
Velocimeter with its vertical connector pointing up.

4.5.2 Lycoming O/IO-540

Occasionally these engines have a front-mounted propeller
governor that offers good access and is a good place to mount.
The forward-most case half bolt is always an option. On some of
the up-draft installations, there are free threaded bosses near the
starter.

4.5.3 Continental O/IO-470/520/550

Use the forward-most backbone bolt, if it is accessible.
Otherwise, use a forward oil cooler mounting bolt. Use the bolt
closest to the crank shaft. Some engines have a seal plate at the
crank shaft front seal with exposed studs. These seals are close to
the spinner and clearance may be tight, but it is a usable balance
location.

4.5.4 P&W R-985/2800

Mount the Velocimeter in the horizontal position on the crank
shaft thrust plate immediately behind the propeller, using a
slotted Velocimeter bracket (the nut cannot be removed). It is not
necessary to mount a check Velocimeter on radial engines.

4.5.5 Flat Opposed General Rules

Mount the Velocimeter as close to the plane of rotation of the
propeller as possible, 90° to the piston travel. Stay within 6 to 8
in. from the engine center line.

4.5.6 Radial Engine General Rules

Mount the Velocimeter as close to the plane of rotation of the
propeller as possible and 90° to the travel of the master cylinder
(connected to the master rod).

4.5.7 Turbine Engines

TPE-331 - Use a vertical mounting (up or down) on the face of

the reduction gearbox. No survey Velocimeter is necessary.

NOTE: Many TPE-331 applications have

PT-6A - Mount the Velocimeter on the tachometer generator

pad or the over-speed governor pad (whichever is most easily
accessible). Angle the pads slightly in at the top. This action
does not significantly affect the signal from the Velocimeter. The
Velocimeter may point up or down. No survey Velocimeter is
required.
