Ransburg Evolver 303 Solvent Applicator A11976-XXX - Manual (Page 21)

APPLICATOR AND
MANIFOLD ASSEMBLY
(See Figures 4, 5, and 6)
The tubing, hose, and low voltage cable come
bundled from the factory. Pull the bundle through
the robot spacer plate and robot wrist carefully
to prevent any cuts on the cable or hoses. Use
the six (6) socket head cap screws (76566-24C)
included with the rear manifold tubing assembly
to attach the rear manifold assembly (A12000 or
A11061) to the robot spacer plate (see Table 1).
Connect each signal line as required per "Signal
Identification Tables (English and Metric) Tubing
Bundles" in the "Installation" section.
Rear Plate Assembly
The rear 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 interior air
supplies are ported through the five (5) support
rods and also directly tubed to the upper manifold
assembly. On the exterior side of the rear plate,
the ports are provided with o-ring seals so that
the applicator 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 on the back of the robot plate. The rear
plate of the applicator assembly is secured to the
robot plate with a threaded retaining ring.
Break-Away Feature (Optional)
The Evolver 303 can be converted to have a break-
away feature, by replacing the five (5) stainless
steel screws with five (5) special designed plastic
screws (77524-00). This feature is meant to re-
duce the damage to the applicator, robot, etc. If
a collision occurs, the five (5) plastic break-away
screws fail and the applicator will break free. This
will leave the break-away ring and the mounting
ring attached to the robot.
Power Supply and Controls
The high voltage cascade located inside the Evolv-
er 303 is controlled by the MicroPak control unit.
The low voltage ouput of the MicroPak is multiplied
by the internal cascade to the high voltage level
required. This eliminates the need for a high volt-
age cable. A low voltage cable interconnects the
cascade and the MicroPak control. The MicroPak
Eurocard format is designed to fit in a conventional
19-inch or 1- inch rack and requires a 24V power
input at a maximum 3 amps. The MicroPak and
the internal cascade will produce voltages up to
100,000VDC.
The MicroPak is designed to electronically limit
current to provide safe operation in a spray booth.
The voltage and current draw of the applicator are
continuously displayed on the MicroPak control
panel. Voltage and over-current limits are ad-
just-able 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 Evolver 303 and MicroPak can be controlled
by a programmable controller. A Serial Digital
Module pneumatically controls the paint and
dump valves located on the applicator. An I/O
module provides communication between these
modules and the PLC.
The above modules are mounted in one 19-inch
rack and interconnected through a common
mother board.
