23.6 Noise and the OmniCure S2000 PRO/ELITE
Using the S2000 PRO/ELITE 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.
23.6.1
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.
23.6.2
Determining the Noise Level in Your Environment
If the S2000 PRO/ELITE, 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
PRO/ELITE, 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
PRO/ELITE.
