Safety Considerations
General
Safety
MVR vision metrology systems are designed for safety and proper ergonomics during
normal use. Exercise caution when lifting, handling or moving the system to avoid
personal injury and to maintain equipment calibration and measurement performance.
Disconnect all power sources prior to moving or working on the equipment. Consult
Starrett if you have any question regarding transporting, using or maintaining this
system.
Electrical
Safety
MVR vision metrology systems do not contain hazardous AC line voltages, as these
are contained on the input side
of the system’s two AC adapters, which are UL listed.
The supplied voltages are 24 Vdc to the metrology unit and 19.5 Vdc to the all-in-one
PC. Even at these low voltages, there is the potential of electrical equipment damage
caused by accidental short circuits. For maximum electrical safety and minimal risk to
the equipment, follow the guidelines below:
Ensure that the power receptacles for the AC adapters are properly grounded 3-
prong polarized 120V AC types for use in North America or appropriate safety-rated
receptacles for use outside of North America.
Do not operate the system with the housing open except for service by a factory trained
technician.
Keep liquids away from the system, and do not operate the equipment in excessively
humid conditions, as water can cause short circuits.
Keep metal filings away from the system, as such debris can cause short circuits.
Do not operate the equipment around volatile or flammable solvents, as local electrical
heating could cause ignition.
Disconnect power, or do not plug in the power cord, if hazardous conditions exist such
as a damaged or frayed power cord, a damaged or improperly grounded power recep-
tacle, equipment exposure to liquid spills or excessive moisture, or impact damage.
Have the system inspected by authorized personnel before operating.
Mechanical
Safety
MVR systems are heavy. To avoid possible back injury, use multiple persons to lift.
Bend your knees, not your back.
There are moving components and potential pinch points, so do not place hands and
mechanical items near pinch points. The risk of injury from these pinch points is
minimal, since all motion is slow and manual, not motorized.
3.8
Equipment On/Off Control
MVR systems have two On/Off switches: one on the back right of the metrology unit right above
the electrical connections, and one in the upper left of the all-in-one PC. Turn the system off when
not in use.
Before removing power, first close all computer files and applications, then shut
down the computer using the Windows
“Shut down” button. Otherwise computer
files could be corrupted by the sudden loss of power.
3.9
Fuses
There are no fuses in the system.
