> Pneumatic input to the turbine air inlet must
be controlled to prevent the turbine from ex-
ceeding the maximum rated speed of 70,000
rpm. (See "Specifications" in the
"Introduction" section.)
> High voltage must never be turned on while
cleaning solvent is being sprayed either
through the applicator supply or the cup wash
line. High voltage and both solvent triggers
must be interlocked (direct charge only).
2. It should not be possible for the coating
material to be sprayed unless the turbine is
spinning.
3. Two Interconnected bearing air ports are
provided, one for supply air and the other
to be used as a return signal for measuring
bearing air pressure at the atomizer. If
bearing air falls below 80 psi (551.6 kPa)
at the atomizer, the turbine air should be
automatically interlocked to shut off. This
interlock is provided by the Serial Atomizer
Module. (See current "Serial Atomizer"
manual.)
4. High voltage must be interlocked with the
solvent valve pilot signal to prevent solvent
flow while high voltage is energized (direct
charge only).
5. Turbine air and brake air must be inter-
locked to prevent both from being used
simultaneously. This interlock is provided
by the Serial Atomizer Module. (See cur-
rent "Serial Atomizer"manual.)
6. Any other interlocks required by local national
code or international code.
> Bell cup must be rotating at least 30,000 rpm
when fluid is triggered. Turning on fluid with-
out the bell cup spinning may flood the turbine
and cause damage to components.
