SAFETY PRECAUTIONS
Ransburg
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. Differences 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 differences.
W A R N I N G
!
The user MUST read and be familiar with
the Safety Section in this manual and the
Ransburg safety literature therein identied.
This manual MUST be read and thor-
oughly understood by ALL personnel who
operate, clean or maintain this equipment!
Special care should be taken to ensure that
the WARNINGS and safety requirements for
operating and servicing the equipment are
followed. The user should be aware of and
adhere to ALL local building and re codes
and ordinances as well as NFPA-33 SAFE-
TY STANDARD, prior to installing, operating, and/or servicing this equipment.
W A R N I N G
!
The hazards shown on the following
page may occur during the normal use of
this equipment. Please read the hazard
chart beginning on page 3.
Careful study and continued use of this manual
will provide a better understanding of the equip-
ment and process, resulting in more efcient
operation, longer trouble-free service and faster,
easier troubleshooting. If you do not have the
manuals and safety literature for your Ransburg
system, contact your local Ransburg representative or Ransburg.

N O T E
The high voltage is interlocked elec-
trically with the uid trigger switches.
When a uid switch is triggered on, the
HV will automatically be turned off.
W A R N I N G
!
Wear the proper safety protection such as
eye and ear protection.
NEVER wear loose clothing while work-
ing around the applicator.
NEVER run the applicator with anyone
near the bell. Serious injury COULD OCCUR
if the bell is contacted while it is rotating.
NEVER stop the rotation of the bell by
hand. Use the manual air brake supplied on
the test stand panel.
NOTES
Ensure ALL items in the test area are
grounded. Ensure there are NO open con-
tainers of ammable materials in the test
area.

AREA
Tells where hazards
may occur.
Spray Area
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 off 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 100°F (37.8°C).
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 maintenance may create a hazard.
Personnel must be properly
trained in the use of this equipment.
High voltage equipment is utilized. Arcing in areas of ammable or combustible materials may occur. Personnel are
exposed to high voltage during
operation and maintenance.
Protection against inadvertent
arcing that may cause a re
or explosion is lost if safety
circuits are disabled during
operation.
Frequent power supply shutdown indicates a problem in
the system which requires
correction.
An electrical arc can ignite
coating materials and cause
a re 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.

GENERAL INFORMATION
The Ransburg Applicator Performance Test
Stand was developed to assist in determining the
applicator’s level of performance in an off-line condition. Ensuring the applicator functions properly
after any maintenance has been performed to it
off-line reduces the costs associated with verifying
performance during production. With line speeds
critical to the through-put of a facility, every uptime
minute counts to underwrite protability. This
Test Stand device helps to ensure the applicator
performs correctly when it is put into service.
This Test Stand will verify performance of single
uid applicators, bearing air, shaping air, brake air,
turbine drive air, and ber optic functionality. As
well, it checks kV and µA electrical performance
of the applicator.
The Test Stand was developed with the user and
the safety of the user in mind. The user must
become familiar with the overall function and
operation of the unit.
