Ransburg MMA-570 Direct_Ind Charge Atomizer A13366 - Manual (Page 10)

GENERAL DESCRIPTION
MMA-570 Direct and Indirect Charge
The MMA-570 can be configured for direct charging
of solvent borne paints. By simply removing the
high voltage ring and adjusting the high voltage
cable input position, the MMA-570 can be used
with a wide range of solvent borne paints.
The MMA-570 can also be configured as an in-
direct (external) charging electrostatic applicator
for use with grounded waterborne fluid systems.
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
secured to the turbine manifold assembly with a
turbine retaining ring.
Turbine Manifold Assembly
The assembly is secured to the mounting manifold
assembly with a quick disconnect ring which allows
for easy installation and inspection.
Mounting Manifold Assembly
The air and fluid ports are compactly oriented for
use in robotic or machine mount applications. A
wrist adapter is available for adapting to virtually
any robot mounting configuration.
Power Supply and Controls
The High Voltage Cascade (74793-XX) is located
outside the MMA-570 and is controlled by the Mi-
croPak control unit. The low voltage output of the
MicroPak is multiplied by the cascade to the high
voltage level required. The high voltage output of
the MicroPak is multiplied by the cascade to the
high voltage level required. The high voltage is
supplied to the atomizer by a High Voltage Cable
(A10560-XX). A low voltage cable interconnects
the cascade and the MicroPak control. The Mi-
croPak format is designed to fit in a conventional
19-inch or 10-inch rack and requires a 24 power
input at a maximum 3 amps.
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
internal safety circuits will shut down the system
on over-current and cable faults.
With additional control modules, all of the functions
of the MMA-570 and MicroPak can be controlled
by a programmable controller. A Serial Atomizer
Module pneumatically controls the speed of the
rotary atomizer with dynamic feedback through a
fiber optic transmitter located on the applicator. A
Serial Digital Module pneumatically controls the
paint, solvent, and dump valves located on the
atomizer. An I/O module provides communication
between these modules and the PLC.
The previously stated modules are mounted in
one 19-inch rack and interconnected through a
common mother board.
