Warranty
The ACES Systems’ Viper Model 4040 Analyzer is warranted to be free of defects in
material and workmanship for a period of 60 months (5 years) following the purchase date.
Warranty does not cover the analyzer unless it is properly used, stored, and maintained in
accordance with the provisions of this manual. Accessories are warranted for a period of 12
months (1 year). The original manufacturer may cover individual accessories not
manufactured or assembled by TEC for longer periods.
The required annual calibration must be complied with to validate the terms of this
warranty. Warranty replacement and / or repair will not be honored on any unit which is
overdue an annual calibration at the time of the warranty claim. If your calibration is overdue
and no warranty claim is being made, you need only have your overdue calibration completed
to re-validate your warranty. Warranty is limited to supplying Purchaser with replacement or
repair of any unit or accessory item which, in TEC's opinion, is defective. All repaired or
replacement parts will be warranted only for the unexpired period of the basic warranty. All
warranty work will be on a return-to-the-factory basis. Shipping cost to the factory will be
borne by the Purchaser. Warranty shall not apply to any product that, in the judgment of TEC,
has been subjected to misuse or neglect, or has been repaired or altered outside the TEC
factory in any way, which may have impaired its safety, operation, or efficiency, or to any
product that has been subjected to accidental damage.
Warranty does not cover any cost incurred by Purchaser as the result of the purchase of TEC
products. Nor does Warranty cover cost incurred by Purchaser for labor charges for
replacement of parts, adjustments, or repairs or any other work performed by the Purchaser or
his agents on, or connected with, TEC-supplied products. Warranty is expressly in lieu of any
and all other warranties or representations, expressed or implied, and of any obligations or
liabilities of TEC to the Purchaser arising from the use of said products, and no agreement or
understanding varying or extending the same will be binding upon TEC unless in writing,
signed by an authorized representative of TEC. TEC reserves the right to make changes in
design or additions to, or improvements in, products at any time without imposing any
liability on itself to install the same in any product manufactured or supplied prior thereto.
Viper 4040 UserManual
3 - Preface
CalibrationandCertification
Your ACES Systems equipment is calibrated and certified per NIST standards, effective the
date of shipment. TEC requires the unit to be calibrated by TEC or a TEC authorized service
facility on an annual basis to insure accuracy and currency of installed electronic
components. In addition, the vibration sensors, pressure and temperature transducers (if
applicable) should also be calibrated on an annual basis or when dropped, damaged or suspect
of improper operation. The analyzer will be identified as calibrated by a sticker stating the
date of calibration and next due date of calibration. A certificate of calibration will be
provided to you to verify compliance to inspectors. A permanent record of your calibration is
maintained by TEC. You may obtain a copy of your calibration by contacting ACES
Systems. A calibration reminder letter will be sent to you approximately 30 days prior to the
expiration of your calibration. For information about calibration services please visit:
http://www.acessystems.com/returnprocess.htm and/or
http://www.acessystems.com/servicecenters.htm.
NOTE
The annual calibration is required in order to comply with the terms of the
5-year warranty. See “Warranty” in this section for details.

or provides raw data for use with polar charts, performs vibration surveys, TFE731
Performance runs, (in conjunction with the ACES 1752B JEDA) and transient analysis.
Engine, airframe, propeller, or rotor-specific setups can be loaded and stored into the analyzer
by the user, then recalled to automatically configure the analyzer for the task at hand. These
“Setups” store influence coefficients for balancing functions, which the analyzer updates with
each balance job to minimize the number of required runs for balancing fans, propellers,
rotors, or shafts.
The analyzer is capable of true, four-channel simultaneous data acquisition and provides full
graphic-spectrum capabilities including on screen display of limits and component
identification taken from an installed fault frequency database.
The Viper 4040 allows you to print spectra and balance jobs directly to a serial printer, and
with the use of a serial-to-parallel converter, to a parallel printer for inclusion in aircraft
records or as file copies. (See chapter 21 of this manual for details on printing.) The analyzer
also has a USB port if your PC is so equipped. Survey spectra and balance reports can be
transferred directly to a personal computer for storage, trending, or manipulation for
inspection or troubleshooting purposes via the companion software ACES AvTrend.
Overall, the analyzer is designed as a lightweight, portable unit with accuracy and ease of use
as primary design goals.
The subsequent chapters of this manual explain the functions and features of the analyzer,
supporting information, and troubleshooting. The remainder of this chapter presents tips on
effectively using the manual.
1-2 – Introduction 1
1.1-Notes,Cautions,andWarnings
Throughout this manual you will encounter “notes, cautions, and warnings.” They will be in
BOLD capital print centered above a short paragraph. The information in the paragraph is
defined as follows for each of the three categories.
NOTE
Information considered essential to emphasize for clarity or to ensure the related
procedure is correctly accomplished.
CAUTION
Information that if not heeded, may result in the damage or faulty operation
of equipment.
WARNING
Information that if not heeded, may result in damage or destruction of equipment
and/or injury to personnel.
1.2-Conventions
The following are writing conventions used throughout the manual to describe certain
concepts.
1. This manual indicates keys/keystrokes in square brackets. For example: [ENTER],
[CLR], [5], [F1].
2. The term “select,” as used in this manual, means to highlight the item on the current
menu by using the arrow keys, then pressing the [ENTER] key.
3. The term “Setup,” as used in this manual, means the complete set of information entered
into the analyzer or created with AvTrend and electronically stored in the analyzer’s
memory or in the AvTrend software files for the purpose of completing a balance,
vibration analysis, or track function. This stored information may then be downloaded
from AvTrend to the analyzer, or if stored in the analyzer already, recalled from a
“Setup” menu presented for the various functions to rapidly configure the analyzer based
on the information contained in the Setup.
4. The term “Job,” as used in this manual, means the stored Setup information plus the
collected balance, vibration, track, and/or spectral data, and recorded corrective action
taken (if applicable) to correct an undesirable condition. In other words, it is a record of
the analyzer configuration, acquired data, computed data, and user entered data used in
the course of completing the maintenance task.

5. The “Banner” is the uppermost portion of the screen display, which defines its
relationship to the currently-running analyzer function. The “Highlight Bar” is the
darkened bar (controlled by the use of the arrow keys, [⇓] and [⇑]) used to identify and
select the current menu item. (See figure below.) These screens and their selection
options are referred to as “banner screen menus” throughout the text of this manual. The
example screen below, for instance, is the “Main Menu” banner screen.
6. The term “field” as used in this manual refers to an area that requires input. Fields appear
on various screens as areas delineated by boxes with either pointed ends (< >) or square
ends ([ ]). Data is entered into the field in one of two ways, either by using the keypad to
type data or by using the [⇒] key to “toggle” or move among the selections that are
preset for the field.
7. The term “Tracker,” as used in this manual refers to the ACES Systems’ Model 540, the
Model 540-2 Optical Tracker, or the Model 550 TraXTM.

2.1. Keypad
The analyzer keypad consists of 31 function keys. (See Chapter 3, “Using the Viper 4040
Analyzer” for keypad operation.)
2.1.1. Located at the top left of the analyzer keypad, the [ON/OFF] key, when pressed once
and released, turns the analyzer power on or off. The analyzer incorporates a power
conservation function. If no activity (keystroke) occurs within ten minutes following
the on keystroke, the analyzer will automatically shut off. If activity does occur
within ten minutes, the analyzer remains on for thirty minutes with no activity before
automatically shutting off. As long as a keystroke is detected at least once every
thirty minutes thereafter, the analyzer remains powered until the [ON/OFF] key is
pressed to turn power off, or the battery’s charge expires.
2.1.2. The [MAIN MENU] key is used as a means to quickly return to the main menu (the
first menu that appears when the analyzer is powered on) without the necessity of
multiple steps. When pressed momentarily then released, this key produces the same
action as turning the analyzer power off, then back on. The key may be used to
escape screens where [BACKUP] will consume too much time for the user. Pressing
the [MAIN MENU] key causes all in-progress functions to cease and incomplete
balance or survey data to be lost in whole or in part. Holding the [MAIN MENU] key
down for more than two seconds will turn the analyzer off.
2.1.3. The [BACKUP] key allows the user to back up one step in the current running
procedure to make corrections or immediate changes. The [BACKUP] key is also
used to escape an active screen where no other options for exit are available.

2.1.4. Five function keys ([F1], [F2], [F3], [F4], and [F5]) are located directly below the
analyzer’s screen. Five small rectangular boxes on the screen directly above the keys
define their use as it corresponds to each screen. The purpose of each key may
change from screen to screen. If any of the screen boxes are blank, the box’s
corresponding key has no function in that screen.
2.1.5. Two contrast keys are located to the left and right of the main body of keys above the
[BACKUP] and [ENTER] keys. The left or decrease key is used to lower the screen
contrast and the right key (shown above) which is visually opposite, to increase the
screen contrast. These keys are fully functional for all phases of operation when the
analyzer is powered. Each key press will produce an incremental increase or decrease
in the screen contrast.
2.1.6. The [PRINT] key is inoperative at this time.
2.1.7. The [BACKLIGHT] key, when pressed once, turns the LCD backlight on or off.

2.1.8. The [ENTER] key is pressed to accept data or a menu selection and set that selection
into motion. The key is used in survey and balance procedures to proceed to the next
step.
2.1.9. Pressing the [HELP] key allows you to access guidance and/or examples of
information that can be entered into the current field.
2.1.10.The ten alphanumeric keys (0 through 9 / A through ?) are used to input
alphanumeric values into the analyzer. A single press followed by a one-second delay
returns the numeric value (first character) of the key. Two rapid presses followed by
a one second delay returns the second character (first of the three alpha characters) of
the key. Three or four rapid presses followed by a one-second delay, returns the third
or fourth (second or third alpha) characters of the key, respectively. For example, if
you want to type the letter “N” which is the third character on its corresponding key,
press the key three times rapidly, and then stop for one second. The letter “N” should
appear on the screen.
2.1.11.The [CLR] key is used to clear input in the current field.
2.1.12.The four arrow keys ([UP], [DOWN], [LEFT], and [RIGHT) are used to select, move
between fields and positions within a field, or highlight menu items on screen. They
are also used in various functions to "toggle" between choices, to increase or decrease
screen values and graphic display sizes, and to change the field value or cursor
position.

2.1.13.The symbols key ([. @%&]) has multiple functions. The “.” is used for placement of
a decimal in fractional numbers such as 98.6. The other characters on this key are
used as they would be in normal text such as “54 grams @ 230 degrees” or “3%
error,” or “Left & Right propellers.” To type any of the symbols on this key, follow
the same procedure described in the preceding paragraphs that are used for the
alphanumeric keys.
2.1.14.The [SPACE] key is used to enter a separating space in a text line. When entering
numeric values the plus (+) and minus (-) portions of the key are used to change a
positive number to a negative value or a negative number to a positive value.
2.2. -Screen
The full graphics Liquid Crystal Display (LCD) screen is how the analyzer communicates
with the user. In computer terminology, the screen is the “graphical user interface.” The
screen displays messages, menus, selection lists, graphic illustrations, and survey plots. The
display is 2.9 inches high by 3.85 inches wide. It is an adjustable-contrast, backlit LCD with a
320 x 240 dot-matrix display. Although the screen displays various font sizes dependent on
the current function, a typical screen such as the main menu it is capable of displaying 40
columns and 20 lines of text at one time. The backlight is turned on automatically when the
analyzer is powered up and can be turned off and on using the backlight key. Screen contrast
is controlled by pressing one of the two contrast keys to the left and right sides of the main
body of keys.
NOTE
If the analyzer is exposed to extremes in temperature, either heat or cold, the LCD may
darken or lighten to a point that it cannot be clearly read. If this occurs, adjust the
contrast to compensate for the change. If this fails to return the LCD to a viewable
state, remove the unit to an ambient room temperature of 65 – 85 degrees F. The LCD
should return to its previous state in approximately 30 minutes.
