via the wall outlet connected to the IRP2+)
Identify the EMI source by turning potential
sources on and off (or fully up and fully down)
and watching for any change in the IR Test LED
on your IRP2+. Once you have identified the
source of interference:
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) Shield the sensor with a metal J-Box.
3) Connect the Sensor’s GND terminal to true
earth ground (if this isn’t feasible use the IRP2+
GND terminal).
4) Place a ferrite ring around the cable creating
the interference. Ferrite rings can be purchased
from an electronic supply store.
