Pressing the square button again
brings up the next screen which allows
the machine type (motor or pump) to
be selected.
Motor - Electrical machine normally
with sleeve or rolling element bearings
and depending on size, operating
speeds above 120RPM to
15,000RPM.
Pump - Multivane impeller with sepa-
rate or integrated drive (centrifigul,
mixed flow, and/or axial flow) with
sleeve or rolling element bearings.
If a motor is selected the size must
be selected (under or over 300kW) or
if a pump is selected, it must be
specified whether it has an integrated
or external drive unit.
Selecting the machine type and size
allows the ISO alarm levels to be set
accordingly, as does specifying the
type of machine mounting (rigid or
flexible).
As a basic “rule of thumb”, unless a
machine is bolted down to concrete,
it should be considered as being
flexible.
Most motors and pumps are mounted
on some kind of frame or structure
and as such should definitely be
considered as flexibly mounted.
