•Documentation conventions
•Technical support
•Safety
•Class 3B (IIIb) laser safety information

•Emerson 430 SpeedVue side view with labels
•Emerson 430 SpeedVue bottom view
•Connect the Emerson 430 SpeedVue to the analyzer
•Cleaning the Emerson 430 SpeedVue
The Emerson 430 SpeedVue is a high-performance speed sensor designed to
detect the turning speed of rotating equipment. Use the Emerson 430
SpeedVue either handheld (i.e., attached to the AMS 2140) or magnetically
mounted. The Emerson 430 SpeedVue is typically powered by the analyzer
and uses a short signal/power cable to keep the package convenient and neat
during operation.
The Emerson 430 SpeedVue uses laser light to detect rotational speed
without reflective tape. Using reflective tape may enhance the return signal,
but in ideal cases, the Emerson 430 SpeedVue does not require any tape or
paint marks and may function up to approximately 30 feet away from the
equipment.
The Emerson 430 SpeedVue may also be used to detect belts and pulleys and
display the result in feet per minute, if desired.
Automatically detect the speed
When used with supported vibration analyzers, the Emerson 430 SpeedVue
automatically detects, displays, and records the rotational speed without
leaving the route. The speed value displays below the plot.
Manually detect the speed
Locate the turning speed by simply marking the appropriate peak on a
spectrum plot after the data is collected. Use a cursor to mark the peak, and
the value displays below the plot.

1.1 Documentation conventions
The following conventions are used throughout:
Note
A note paragraph contains special comments or instructions.
CAUTION!
A caution paragraph alerts you to actions that can have a major impact on
the equipment or stored data.
WARNING!
A warning paragraph alerts you to actions that can have extremely serious
consequences for equipment and/or personnel.
1.2 Technical support
The Emerson 430 is not user serviceable. Please contact the manufacturer for
any service or technical support.

1.3 Safety
Emerson 430 SpeedVue Sensor may not be compatible with the AMS 2140
labeled ATEX/IECEx Zone 2. The Emerson 430 is not permitted in hazardous
areas; and it may not function with the ATEX-certified AMS 2140 even in a
safe area.
WARNING!
Do not use the Emerson 430 SpeedVue in a hazardous location.
WARNING!
For proper use of the Emerson 430 SpeedVue with your analyzer, refer to the
analyzer’s approved installation drawing.

WARNING!
•Laser radiation. Avoid direct eye contact. Avoid exposure to beam.
•Avoid exposure. Laser radiation is emitted from the aperture.
•Using controls, making adjustments, or performing procedures other
than specified herein may result in hazardous radiation exposure.
1.4 Class 3B (IIIb) laser safety information
What is a Class 3B Laser?
Class 3B lasers are hazardous for eye exposure. They can heat skin and
materials, but are not considered a burn hazard. For visible-light lasers, Class
3B lasers’ output power is between 5 and 499 milliwatts.
Note
The Emerson 430’s output power is <5mW. The IEC identifies the laser as
class 3B due to the duration of time the laser can be exposed during
operation.
Safe Use Guidelines
A Class 3B laser can cause eye injury. The more powerful the laser, the
greater the chance of injury.
Use of laser protective eyewear is suggested or recommended.
A Class 3B laser can be a distraction, and are a glare or flash blindness hazard
for users and coworkers.
Always be aware of the beam location. Keep it away from eyes and heads.
Watch out for reflected beams from glass and shiny surfaces.
ONLY ALLOW USE BY TRAINED/RESPONSIBLE PERSONS.
Class 3B Laser eye injury hazards
Class 3B visible-light lasers are hazardous for eye exposure. They can cause
burns to the retina. A person cannot turn away or blink fast enough to
prevent retinal eye injury from a nearby Class 3B laser.
At the low end, around 5 to 50 milliwatts, a Class 3B laser poses a moderate
risk of eye injury. It is unlikely that a handheld beam aimed from more than a
few dozen feet away would cause injury—laser light could not stay on one
spot on the retina long enough for heat to build up to injurious levels.
However, the risk is increased if the beam is held steady or if the laser is
relatively close to the eye.
August 2018 User Guide

As the laser power increases, the risk of eye injury also increases. At the high
end, around 250 to 500 milliwatts, even a brief exposure could cause retinal
damage.
Avoid all eye exposure to beams from Class 3B lasers. This includes
unintentional or accidental exposures. Be careful to keep the beam away
from eyes and faces.
Also, remember that reflections off mirrors, glass, and shiny surfaces can be
just as hazardous as the direct beam. Avoid reflected Class 3B beams the
same way you would avoid the direct beam.
The Nominal Ocular Hazard Distance (NOHD) for a lower-powered 50 mW
Class 3B visible-beam laser with a tight beam (0.5 milliradian divergence) is
330ft (100 m).
If you are closer than the NOHD distance to the laser, there is a possibility of
retinal damage if the direct or reflected beam enters the eye. The closer you
are to the laser and the longer the beam is in the eye, the greater the chance
of injury.
Class 3B Laser skin injury hazards
A Class 3B laser is not normally considered a skin or materials burn hazard.
However, if the laser “dot” is kept motionless on skin at close range, heat can
be felt. The more powerful the Class 3B laser, the sooner the heat will build
up.
Do not deliberately attempt to burn skin. This can be very painful, can take
a long time to heal, and can leave a permanent scar.
Class 3B Laser protective eyewear
Laser glasses or goggles are suggested for lower-powered Class 3B lasers,
and are recommended for higher-powered Class 3Bs. They should be
selected to protect against the laser’s power and wavelength.
The eyewear should not block out all of the laser’s light. This is because it is
necessary to see where the laser “dot” is in order to safely work with the
laser. Because the eyewear is blocking some or perhaps all of the laser’s light
(for example, a hazardous reflection) you should still use caution even when
using the laser protective eyewear.
As you use the laser, any other persons in the area should also have the same
type of laser protective eyewear as you.
DO NOT USE SUNGLASSES FOR LASER PROTECTION.
User Guide August 2018
8
Sunglasses are NOT laser protective eyewear. They are not rated to ensure
light-attenuating protection. Most sunglasses will not block enough laser
light to significantly reduce hazardous exposures.
Markings
The Emerson 430 has a laser radiation label that warns users to avoid
exposure to the laser beam.
