Ransburg 9040 Aerobell Control Module 78387-00 - Manual (Page 9)

INTRODUCTION
GENERAL DESCRIPTION
The 9040 Aerobell Control Module provides
pneumatic control functions for Aerobell ® appli-
cators sold as part of the 78394 or 78399 Single
Bell Packages. The Aerobell Control Module is
included as a part of these packages.
The Aerobell Control Module consists of a 78387
Control Unit and a 78395 Remote Manifold as-
sembly (see Figure 1). Together, these two units
provide the following functions:
Fluid Control: A 0 to 60 psi adjustable pilot reg-
ulator provides an output that can be connected
to the fluid regulator of the applicator to control
material delivery. A gage and On/Off valve are
also provided for this output.
Shaping Air Control: A 0 to 60 psi adjustable pilot
regulator in the Control Module provides output to
a 1:1 volume booster on the Remote Manifold. A
toggle valve in the Control Module provides On/
Off control of this air signal. The output of the
volume booster is used to supply shaping air to
the applicator. A second output of the volume
booster is connected back to the Control Module
to supply a gage.
Atomization Air Control: A 0 to 60 psi adjustable
pilot regulator in the Control Module provides
output to a second 1:1 volume booster on the
Remote Manifold. A toggle valve in the Control
Module provides On/Off control of this air signal.
The output of this volume booster is used to supply
atomization air to the applicator. A second output
of the volume booster is connected back to the
Control Module to supply a gage.
Trigger Control: A toggle valve output allows
On/Off control of the applicator fluid trigger valve.
Dump Control: A toggle valve output allows On/
Off control of the applicator fluid dump valve.
Solvent Control: A toggle valve output allows
On/Off control of the applicator solvent valve for
the Aerobell 33 TM . Not used for the standard RPM
Aerobell.
Bearing Air Interlock: A sense valve is provided
that only allows atomization air output if the bearing
air is above 60 psi. This prevents possible turbine
damage from operating the turbine at too low of
a pressure.
Fluid Interlocks: Two valves are used to disable
the solvent and trigger outputs if atomization air
is off, thus ensuring that the turbine is spinning
and atomization air is on, when fluid is supplied
to the applicator. This prevents possible material
backup into the applicator.
High Voltage Interlocks: A solenoid is provided
to prevent solvent or dump activation whenever
the applicators’ High Voltage Power Supply is on.
In addition, an output is provided that ensures the
Power Supply is disabled whenever the solvent
or dump signals are active.
>
The high voltage interlocks must be
connected as described in the installation
section of this manual to prevent possible
operation of the dump or solvent functions
when high voltage is present.
