PROCESSPROCESS
PROCESS
PROCESSPROCESS
This process is a method for electrostatically
applying coatings to objects. A power supply
produces a high voltage charge which is supplied
to the applicator, creating an electrostatic field
between the applicator and the target object. The
target is electrostatically grounded through its
support which may be either stationary or moving.
A regulated fluid system delivers coating material
to the applicator, where it is atomized forming a
spray mist. There, under the influence of the
electrostatic field, the atomized coating becomes
electrostatically charged. The charged particles
are attracted to and deposited on the grounded
target object. The forces between the charged
particles and the target are sufficient to turn
overspray around and deposit it on the back
surface of the target. Therefore, a higher
percentage of the spray is deposited.

There are two single-head models of the EFM
Applicator. Each model differs in the applicator to
axis orientation of the spray head, these models
are:
Two dual-head versions of the EFM Solventborne
Applicator are also available, designated EFMDTM.
The dual-head version is identical to the EFM
applicator with the exception of an additional spray
head mounted to the applicator body. EFMD
Solventborne Applicators are primarily used where
high volume fluid delivery is required. These
applicators supply twice the fluid delivery over
Single-Head EFM Solventborne Applicators. The
EFMD Solventborne Applicator is available in two
different configurations as follows:
Both EFM and EFMD Solventborne Applicators

The EFMTM Solventborne Applicator line consists
of single and dual-headed 100 kV automatic
electrostatic spray applicators. Developed for
use on robots or reciprocators, the EFM
solventborne applicator incorporates a quickdisconnect manifold and swivel tubing connections
to minimize downtime. Internal fluid and air
solenoids and an internal high voltage power supply
provide the user a compact, efficient tool for the
application of electrostatic coatings. Because this
is a grounded fluid system, the EFM solventborne
applicator is highly suitable for applying a wide
range of solvent reduced coatings such as enamels,
lacquers, two-component and other such coatings.

The spray head(s) and valve manifold contain the
fluid, air, and high voltage passages. Although the
quick-disconnect base manifold and robotmounted manifold are fabricated from aluminum,
all fluid passages are contained within stainless
steel and nylon fittings and are compatible with
halogenated hydrocarbon solvents. The robot
manifold incorporates stainless steel swivel fluid
connections. The swivel connections reduce
stress on the fluid lines minimizing breakage. No
aluminum parts are exposed to the fluid path on
either manifold. The high voltage cascade is
entirely encapsulated with a solvent resistant
epoxy.
The high voltage supply for the EFM and EFMD
applicators consists of two major components:
The MicroPakTM Power Supply Control Unit
(LECU5004), and the HP404 Cascade (75933-
00).
The MicroPak power supply control unit provides
a low voltage signal through the robot manifold to
the EFM or EFMD spray applicator. The high
voltage cascade located within the applicator
converts the low voltage DC signal to a high
voltage electrostatic output. See

The distance between the applicator tip and the
article being painted should be between 10 and 14
inches. Excessive distance causes a waste of
coating material and wrap back (paint particles
being deposited on the applicator body or the robot
arm). At close distances the voltage at the tip of
the applicator will be reduced, which decreases
the charging effect of the applicator.

The LECU5004 MicroPak Control Unit provides a
means for the adjustment of the timing interval
between air, fluid, and high voltage. When the
applicator receives a trigger on signal from the
robot PLC, the air solenoid valve actuates. At the
same time the fluid solenoid valve timer is activated.
After the timer times out, the fluid solenoid and the
high voltage timer are activated. This timer delays
the start of the high voltage until after both the air
and fluid are activated.
Timing can be set in nine different timing
sequences, from a minimum of zero to a maximum
of 450 milliseconds. When the electrical signal
from the robot PLC is removed, the timing operates
in reverse. High voltage is shut off, fluid shuts off,
and, finally, the air solenoid valve shuts off. See

Normally the voltage should be set to 90 kV at the
power supply. Some conditions may dictate lower
voltage settings. If Faraday cage areas are
predominant on the item being painted, a lower
voltage setting will aid in coating these areas.
Paints having high metallic flake content will
sometimes align at high voltages. Metallic flakes,
when aligned, become a direct electrical path to
ground and will reduce tip voltage. This problem
can be minimized by making sure that the paint is
being sprayed from the applicator prior to turning
the voltage on. In some cases, a reduction in
applied voltage may be the only way to reduce
alignment.

Instrinsically safe wiring must be separated from
non-intrinsically safe wiring in order to prevent the
transfer of unsafe levels of energy to the hazardous
area. The following are a few recommended
practices:
Safe AreaSafe Area
Safe Area
Safe AreaSafe Area
In the non-hazardous area, intrinsically safe and
non-intrinsically safe wiring must be separated by
one of the following methods:
1. Raceway or conduit
2. Grounded metal or insulated partition between
the intrinsically safe and non-intrinsically safe
wiring

guidelines or recommendations only. For
rules and more detailed practices, refer
to National Electrical Code.
Hazardous AreaHazardous Area
Hazardous Area
Hazardous AreaHazardous Area
In the hazardous area, all intrinsically safe and
non-intrinsically safe wiring must be separated by
the same methods suggested for the safe area.
However, the following requirements must also be
followed:
1. In enclosures containing multiple intrinsically
safe circuits, the terminals for connection must
have a spacing of at least 6mm or a grounded or
insulated partition between the circuits.
2. Devices like limit switches or pressure switches
must not contain a non-intrinsically safe circuit in
addition to an intrinsically safe circuit unless:
3. Airspace of at least 50mm (2 inches) between
intrinsically safe and non-intrinsically safe wiring
and the wires must be tied down to prevent
loosening and shorting together.
The same methods are used for intrinsically safe
and non-intrinsically safe terminals.
RequirementsRequirements
Requirements
RequirementsRequirements
Intrinsically safe wiring must be identified, preferably by color coding of light blue. If light blue is
used on non-intrinsically safe wiring, the intrinsically safe wiring may be marked by other means
such as tagging. This alternate means, however,
must be visible after installation.
a. It is enclosed in a separate compartment, or
b. It is separated by 50mm spacing or contains
a grounded metal or insulated partition.
3. When conduit or raceway is utilized to enclose
intrinsically safe wiring, it must be sealed or vented
so not to transfer the hazardous atmosphere to a
safe area.
Good maintenance is essential to safe and
productive operation. Schedules should be
established by the user, based on the following
general information and observations of the initial
production requirements. The ITW Ransburg
maintenance and safety information should be
made available to each operator.
Normal fire protection measures are necessary,
including proper storage of paints and solvents
and the proper disposal of waste. Ready access
to appropriate fire extinguishing equipment is
required. For details, consult the appropriate
NFPA safety information, your local fire codes,
local painting equipment standards. Reference
OSHA, NFPA-33, and your insurance carrier's
information for additional information.

plug long wire connector (black & red) into fluid
solenoid.
6. Refer to Figure 6b and reinstall shroud [3] and

manifold. Make sure that all o-rings are in place.
The 76494-XXX Robot Manifold Assembly is
mounted to the robot wrist and includes two low
voltage power cables and the fluid/pneumatic tubing
required to operate the EFM applicator. This
manifold assembly utilizes swivel fitting fluid and
dump lines that eliminate hose breakage due to
twisting. The fluid and dump lines can quickly be
removed from the manifold by backing out the
radially mounted spring loaded retaining pins.
This manifold assembly is designed to mount
directly to a GMF P150 robot wrist. When mounting
to an ABB robot is desired, an EMFD-54 adaptor
plate is required. This adaptor plate will move the
face of the manifold plate out 1.250 inches from the
robot wrist. EMFD-54-1 (2.250" thick) and EMFD54-2 (3.250" thick) adaptor plates are also available
if required.

The EMF-430-1, Test Air Cap, is designed for use
with a Test Station or while the applicator is
connected to the robot or reciprocator. The test air
cap is comprised of two air pressure gauges,
pressure gauge stand, special 76131 air cap, and
all required tubing and fittings.
The air cap has two tapped holes for small barbed
tube fittings. The fittings are located so that the
gauges connected to them will measure the actual
cap pressure of the atomization and pattern air.
Using this test cap will assure uniform atomization
and pattern quality, regardless of air supply tube
lengths from one applicator to another.

The EMF-176 is a plastic cylinder that fits over the
air cap retainer. The protector keeps the electrode
and other spray head parts from being damaged
during booth cleaning and at other times when the
spray applicator is not in use.
Provided with each applicator is a tool kit to aid in
the disassembly and assembly of the applicator
during servicing. The contents of the tool kit differs
depending on which applicator is to be serviced.
The following is a breakdown of the two tool kits
offered.
