only:only:
Whenever removing high voltage cables from

equipment, ground the contact end of the cable
by holding the cable such that the contact
touches earth ground for several seconds. Do
not touch the contact until it has been grounded.
This will reduce the possibility of residual charge
causing electrical shock.

The High Voltage Multiplier assembly contains
energy storage components that can cause seri­ous shock injury, and therefore is not field repair­able. Warranty will be voided if the High Voltage
Multiplier seal is broken. If the High Voltage Mul­tiplier is defective contact your authorized ITW
Ransburg representative for exchange or repair.

The High Voltage Multiplier and high voltage
cable contain significant capacitance that will
store charge. Allow approximately 10 seconds
for this charge to bleed off before removing the
high voltage cable from the power supply or
spraygun.

GENERAL DESCRIPTIONGENERAL DESCRIPTION

The ITW Ransburg REA ProcessThe ITW Ransburg REA Process

The ITW Ransburg REA Process

The ITW Ransburg REA ProcessThe ITW Ransburg REA Process

The REA Process is an air atomized method for
applying coatings to objects electrostatically. The
REA system applies a high voltage DC charge to
the applicator nozzle electrode, creating an elec­trostatic field between the atomizer and the target
object. The target is electrically grounded through
its support which may be either stationary or
moving.

A regulated pressure fluid system delivers coating
material to the atomizer. At the atomizer, air is
applied which atomizes the coating material form­ing a spray mist which, under the influence of the
electrostatic field, becomes electrically charged.
The charged particles are attracted to and depos­ited on the target object. The forces between the
charged particles and the grounded target are
sufficient to turn most normal overspray around
and deposit it on the side and back surfaces of the
target. Therefore, a high percentage of the spray
is deposited on the target.

Control UnitControl Unit

Control Unit

Control UnitControl Unit

The MGS 2001 is a multi-gun control unit which
may supply low voltage for up to 20 guns. The
circuitry is designed to lock out all other guns if one
gun is actuated with voltage.

The MGS 2001 unit converts standard AC line
voltage to a high frequency, low voltage signal
ranging from 0 to 10 Vrms. This signal is supplied
to the REA/REM spray gun where it is converted
to DC high voltage. The voltage/current charac­teristic is designed to optimize the charging pro­cess under varying load conditions and to limit the
operating current to a safe maximum value. In
addition to supplying low voltage output to the
spray gun, the MGS 2001 unit also provides
controls for AC power ON/OFF, high voltage
adjustment, a high voltage meter, a current meter,
a HIGH VOLTAGE indicator light, and a POWER

ON indicator light. Additionally, interlock connec­tions for a conveyor, exhaust fan and high voltage
control are provided with all MGS units.

The MGS 2001 also includes an Independent Gun
Control (IGC) board. This board allows the volt­age to each gun to be adjusted independently of
the other guns, if desired.

The MGS 2000C offers the same features as the
MGS 2001. Additionally, the MGS 2000C is
supplied with High Voltage Modules (one for each
gun) that convert the low voltage output of the
MGS control unit to high voltage. This allows the
MGS system to be used with non-cascade (classic)
guns.

Another difference between the MGS 2001 and
MGS 2000C is the use of reed switches in the
transformer, and air flow switches in the latter, to
trigger the high voltage. This results in a larger box
for the MGS 2000C, as the flow switches are
mounted inside the MGS enclosure, compared to
the MGS 2001 where the reed switches are located
in the gun.

> When highly conductive, solvent based

paints are used it is also recommended that the
high voltage control be series interlocked with
the atomization air. This prevents the possibil­ity of a charged stream of fluid creating an arc,
and subsequent fire, as it approaches the floor
(or some other grounded object). Consult your
authorized ITW Ransburg representative for
information on interlocking the high voltage
with the atomization air.

> Always double check that the control unit

is unplugged from its AC outlet before working
with any internal wiring.

3. Using a small blade screw driver, remove
the factory installed test jumper from 1TB-L1
to 1TB-L2 on the door-mounted control unit.

4. Route exhaust fan and conveyor interlock
(supplied by user) wiring through the external
wiring hole on the bottom of the MGS unit
and connect to 1TB-L1 and 1TB-L2 as
shown in Figure 3.

1. Connect supply air to the IN port of the air flow
switch located on the lower right side of the
MGS cabinet.

2. Connect the OUT port of the air flow switch to
the manifold which feeds air to the individual
sprayguns. In multiple MGS applications, the
sprayguns for each MGS must be fed from an
air manifold supplied from the OUT port of that
MGS's air flow switch.
