6-20 Rosco Maximizer 3B Asphalt Distributor
Operation
Electro Motive Radiation
Interference
High Electro Motive Radiation (EMR) produced by
citizen band radios and other sources can interfere
with the function of the Plus One Controller. EMR
causes stray voltages to be induced in the signals to
and from the computer. As a result, the machine could
unespectedly speed up and/or the application rate
could suddenly change.
If EMR is present, the machine should
be tested at a remote site to insure that there are no
abrupt movements or extreme levels of application.
Possible solutions for problems caused by EMR include:
1. Remove the source of the radiation.
2. Move the source of the radiation away from the
computer area.
3. Shield the computer and/or the wiring (particularly
the power lead going to the computer) in metal
enclosures.
