Ransburg RMA-560 Single_Dual Purge Direct A13364 - Manual (Page 10)

GENERAL DESCRIPTION
Bell Cup Assembly
Bell cups are made of high strength Titanium, Alu-
minum or High Wear Coated Aluminum. Serrated
cups are available in 30mm, 55mm and 65 mm.
Non-serrated are available in 55mm and 65mm.
See ordering matrix for exact size and material
combination availability.
Air Bearing Turbine Assembly
The air bearing turbine assembly with bell cup
is mounted to the air manifold assembly with a
turbine retaining ring.
Air Manifold Assembly
The atomizer extension is angled at 60˚ for robot
applications. The fluid feed tube and fiber optic
turbine speed emitter are threaded into the front of
the manifold. The turbine, fluid, and air manifolds
are separated from the bell plate assembly by five
support rods. Nested between the manifolds and
the bell plate is the high voltage cascade.
Bell Plate Assembly
The bell plate assembly is designed to be at
ground potential when mounted to the robot plate
component within the tubing bundle assembly.
The air and fluid ports are compactly oriented for
use in robotic applications. The air supplies are
ported through the five support rods directly to
the air manifold assembly. On the exterior side of
the bell plate, the ports are provided with O-ring
seals so that the atomizer can be quickly mated
and secured to the robot plate.

Robot Plate
The robot plate is a component of the tubing bundle
assembly and intended to be permanently mounted
to the robot. A wrist adapter is also available, which
matches the robot’s mounting configuration. The
incoming air lines, fluid lines, low voltage cable,
and fiber optic cable are connected to the fittings
provided at the robot plate. The bell plate of the
atomizer assembly is secured to the robot plate
with a threaded retaining ring.
Valve Manifold
This manifold can be configured for either single or
dual purge application. The dual purge can allow
two colors to be loaded at one time.
Break-Away Feature (Optional)
The RMA-560 is available with or without a break-
away feature. By replacing the five (5) stainless
steel screws with five (5) special designed plastic
screws (77524-00). This feature minimizes the
damage to the atomizer or robot, if a collision
occurs, the five (5) plastic break-away screws fail
and the atomizer will break free. This will leave the
break-away ring and the mounting ring attached
to the robot. (The applicator will fall to the booth
grate or floor).
Power Supply and Controls
The high voltage cascade is located inside the
applicator and is controlled by the MicroPak con-
trol unit. The low voltage output of the MicroPak
is multiplied by the internal cascade to the high
voltage level required. This eliminates the need
for a high voltage cable. A low voltage cable inter-
connects the cascade and MicroPak control. The
MicroPak format is designed to fit in a conventional
19-inch or 10-inch rack and requires a 24V power
input at a maximum 3 amps. The MicroPak and
the internal cascade will produce voltages up to
100,000 VDC.
The MicroPak is designed to electronically limit
current to provide safe operation in a spray booth.
The voltage and current draw of the atomizer are
continuously displayed on the MicroPak control
panel. Voltage and over-current limits are ad-
justable on the front of the MicroPak. MicroPak
