21.6 Noise and the OmniCure SERIES 2000
Using the SERIES 2000 in a Noisy Environment
What is Noise?
"Electrical noise" is a term used to describe unwanted electronic emissions. Noise
is actually comprised of RFI (Radio Frequency Interference) EMI (Electro Magnetic
Interference) and other similar sources of energy. Electronic equipment may
behave in a non-standard manner (exhibit erratic operation) with the presence of
high Levels of noise. They will continue to behave erratically as long as the noise is
present, unless protected with noise suppressors.
21.6.1
What are Sources of Noise?
Sources of noise are any electronic equipment which utilize or generate a high
frequency AC current and voltage. Specifically, equipment such as metal halide arc
lamps, mercury short arc lamps, xenon arc lamps, switch mode POWER supplies,
pulsed lasers, x-ray equipment, welding equipment and RFI generators are a few
classic examples of large noise producing equipment.
21.6.2
Determining the Noise Level in Your Environment
If the S2000, along with other pieces of equipment, operate abnormally, in an
intermittent or continuous manner, it is quite possible that large Levels of noise are
present. It is recommended that prior to installing the S2000, the user examine any
equipment nearby. If any of the equipment falls into the category of equipment
listed above it is further advised that the user examine the ratings and description
labels on each piece of equipment. Any equipment that does not have a label
indicating that it meets Industry Canada, FCC, or IEC- EMC requirements is a
possible noise source. If any equipment is deemed a noise source, or even
suspected to be a noise source, then additional noise protection should be
incorporated during the installation of the S2000.
