Electromagnetic Interference

EMI (ELECTROMAGNETIC INTERFERENCE)

Identify the source of the interference. The most common sources of electromagnetic interference
are listed in the Installation Considerations section on page 5. To eliminate EMI try the following
methods:

1. Move the sensor or the sensor cable away from the EMI source or move the source of the
EMI away from the sensor or the cable.
2. Connect the Sensor’s GND terminal to true earth ground (if this isn’t feasible use the main
system unit’s GND terminal).There are many methods for reducing interference. Which
solution is best for you depends on your situation. If you require further assistance call Niles
Technical Support at 305-238-4373 or 1-800-289-4434 (M-F 8:00 AM - 7:00PM ET).  You
can also email Niles Technical Support at [email protected].
