Topics covered in this chapter:

•Documentation conventions

•Technical support

•Safety

•Class 3B (IIIb) laser safety information

•Standard equipment

•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.

To view toll free numbers for specific countries, visit

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.

User Guide August 2018

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

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.
