Installation
When installed in a potentially explosive atmosphere, reference should be made to IP4001/SI.
Prior to installation, it is advisable to check the switching function for proper adjustment on a sample
quantity of material (see
“Adjustments” on page 6
). The unit may not work with mediums that are within
the specified density range, but have very large granules or have too little friction.
Handle the device with great care, especially the sensing probe. Any impact on
the sensing probe may ruin its resonance system. A protective shield should be
installed (see inset, right) if the probe is exposed to falling material or an
excessive mechanical load.
