4-18 Setting Up and Using Laser Alignment Fixtures

Introduction to Laser Alignment Fixtures Setup

This section takes you through a step-by-step setup of the UltraSpec 8215/

8225 Laser Alignment Fixtures. Before performing alignment, be sure all

pre-alignment checks have been completed.

Caution!

Prior to mounting the laser alignment ﬁxtures on machine shafts, all

switches operating the machines should be “locked out.” Follow safety

precautions for your facility. Normally, only personnel performing the

alignment should be able to “unlock” any startup switch. After an

alignment has been completed, the work area should be inspected to

ensure that all equipment is clear of rotating shafts/couplings, prior to

removal of the lockout protection.

Caution!

The 8215/8225 Laser Alignment Fixtures use a Class II (CDRH)

laser or Class 2 (IEC) laser. This laser complies with 21 CFR

1040.10 and 1040.11 safety requirements with a power output < 1.0

mW (average) and a pulse repetition of 600 pulses/sec. The pulse

duration is <110 microseconds. However, do not expose the human eye

directly to the laser beam! Warnings are located on each sensor head.

Water vapor or dust can interfere with a target “seeing” its laser. The air

between the sensor heads should be visually clear. Take care to ensure that

the air between the sensor heads is not being heated from steam leaks, unin-

sulated piping, etc. Heated air rising within the span between the sensor

heads can refract the laser beams and cause errors in the alignment read-

ings.

Operate the laser ﬁxtures at ambient temperatures. If the ﬁxtures have been

stored at a different temperature than the ambient temperature, allow the

laser ﬁxtures to reach ambient temperature. Ensure that any heat source

that may be present is not creating a large temperature difference between

the laser ﬁxtures and the ambient temperature. Sunlight itself will not cause

a laser reading problem.
