Before operating, maintaining or servicing any Ransburg electrostatic coating system, read and understand all of the technical and safety literature for your
Ransburg products. This manual contains information
that is important for you to know and understand. This
information relates to USER SAFETY and PREVENTING
EQUIPMENT PROBLEMS. To help you recognize this
information, we use the following symbols. Please
pay particular attention to these sections.
A WARNING! states information to alert you to a situation that might cause serious injury if instructions
are not followed.
A CAUTION! states information that tells how to
prevent damage to equipment or how to avoid a
situation that might cause minor injury.
A NOTE is information relevant to the procedure in
progress.
While this manual lists standard specications and
service procedures, some minor deviations may be
found between this literature and your equipment.
Dierences in local codes and plant requirements,
material delivery requirements, etc., make such
variations inevitable. Compare this manual with
your system installation drawings and appropriate
Ransburg equipment manuals to reconcile such
dierences.

HAZARD
Tells what the hazard is.
Fire Hazard
Improper or inadequate operation and maintenance procedures
will cause a re hazard.
Protection against inadvertent
arcing that is capable of causing
re or explosion is lost if any safety
interlocks are disabled during
operation. Frequent power supply
shutdown indicates a problem in
the system requiring correction.
SAFEGUARDS
Tells how to avoid the hazard.
Fire extinguishing equipment must be present in the
spray area and tested periodically.
Spray areas must be kept clean to prevent the accumulation of combustible residues.
Smoking must never be allowed in the spray area.
The high voltage supplied to the atomizer must
be turned o prior to cleaning, ushing or maintenance.
When using solvents for cleaning:
Those used for equipment ushing should have ash
points equal to or higher than those of the coating
material.
Those used for general cleaning must have ash
points above 100oF (37.8oC).
Spray booth ventilation must be kept at the rates
required by NFPA-33, OSHA, and local codes. In
addition, ventilation must be maintained during
cleaning operations using ammable or combustible
solvents.
Electrostatic arcing must be prevented.
Test only in areas free of combustible material.
Testing may require high voltage to be on, but only
as instructed.
Non-factory replacement parts or unauthorized
equipment modications may cause re or injury.
If used, the key switch bypass is intended for use only
during setup operations. Production should never
be done with safety interlocks disabled.
Never use equipment intended for use in waterborne installations to spray solvent based materials.
The paint process and equipment should be set up
and operated in accordance with NFPA-33, NEC,
and OSHA requirements.

HAZARD
Tells what the hazard is.
Improper operation or mainte nance may create a hazard.
Personnel must be properly trained

High voltage equipment is utilized.
Arcing in areas of flammable or
combustible materials may occur.
Personnel are exposed to high
voltage during operation and maintenance.
Protection against inadver tent
arcing that may cause a re or explosion is lost if safety circuits are
disabled during operation.
Frequent power supply shut-down
indicates a problem in the system
which requires correction.
An electrical arc can ignite coating materials and cause a fire or
explosion.
SAFEGUARDS
Tells how to avoid the hazard.
Personnel must be given training in accordance with
the requirements of NFPA-33.
Instructions and safety precautions must be read
and understood prior to using this equipment.
Comply with appropriate local, state, and national
codes governing ventilation, re protection, operation maintenance, and housekeeping. Reference
OSHA, NFPA-33, and your insurance company
requirements.
The power supply, optional remote control
cabinet, and all other electrical equipment must
be located outside Class I or II, Division 1 and 2
hazardous areas. Refer to NFPA-33.
Turn the power supply OFF before working on the
equipment.
Test only in areas free of ammable or combustible material.
Testing may require high voltage to be on, but
only as instructed.
Production should never be done with the safety
circuits disabled.
Before turning the high voltage on, make sure no
objects are within the sparking distance.
Explosion Hazard /
Incompatible
Materials
3
Halogenated hydrocarbon solvents for example: methylene
chloride and 1,1,1,-Trichloroethane are not chemically compatible with the aluminum that
might be used in many system
components. The chemical reaction caused by these solvents
reacting with aluminum can
become violent and lead to an
equipment explosion.
Aluminum is widely used in other spray application
equipment - such as material pumps, regulators,
triggering valves, etc. Halogenated hydrocarbon
solvents must never be used with aluminum equipment during spraying, ushing, or cleaning. Read
the label or data sheet for the material you intend
to spray. If in doubt as to whether or not a coating
or cleaning material is compatible, contact your
material supplier. Any other type of solvent may
be used with aluminum equipment.

INTRODUCTION
DESCRIPTIONS
The MCV 2 Collet Series Modular Color Changer is a
material valve stack used to control material ow to
an applicator or other material supply equipment.
The stack assembly is made up of several sub-assembled stacks which are then connected together.
The assemblies are available in both Metric and
English tube sizes.
A description of stacks are as follows:
• Bell Wash Module - This may be attached
to the main stack.
• Stand-Alone Bell Wash Module - These may
be mounted separately away from the stack
assembly. An external outlet port is included
to provide a connection to an applicator or
other such device.
• Two and Four Color Block Modules. Both available in 3 styles: Circulating, Daisy Chain, and Dead Head.
• Inline DR-2 Regulator with performance
matching the industry standard
Ransburg DR-1 Regulator.
• Flow Meter Module for use with bottom
ported uid ow meters.
The 78949-00 microvalve was designed to trigger
up to 2-million cycles. The uid and air sections are
separated by a weep port to prevent contamination
between air and uid.

> The color changer MUST be properly grounded. Proper grounding (as described below)
will prevent static charge buildup and possible
discharge from the color changer.
Grounding of the Color Changer
For safety, the color changer MUST be grounded.
Using a 12-gauge wire, ground the output plate
of the color changer to a true earth ground. Using
an ohmmeter, check for ground, testing the earth
ground to the outlet. The resistance should be 10
ohms or less.

PROCEDURES
Determine Location for Color Changer
The color changer should be located as close as
possible to the spray device in order to save paint
and solvent with a color changer. If possible, use an
enclosure to protect the color changer from airborne
paints and solvents.
Calculate Footprint of Color Changer
(See Figure 3)
To calculate the footprint of the color changer add:
• The dimension of the end plate
• The dimension of the purge assembly
• The dimension(s) of the module(s) used to
create the desired number of color valves
• The dimension of the output assembly
